2018-1 "Réduction du ratio de dette publique : quels instruments pour quels effets ?" Benjamin Egron Show Download working paper (on EconPapers) Abstract In the wake of the economic crisis in 2007-2008, european sovereign debt showed a large increase. As a consequence, the possibility of starting a stabilization or a reduction of public debt ratio has become a critical issue for the coming years to restore fiscal sustainability and to ensure compliance with the european treaties. Against this background, the identification of the most appropriate policies to reduce public debt ratio represents a major economic issue, especially in times of low economic growth. The purpose of this article is to assess the ability of different fiscal policies instruments to reduce public debt ratio. From a methodological point of view, we estimate, based on French data, a non-linear model (Threshold VAR) including the main determinants of public debt ratio : public spending, tax revenues, GDP and price index. The threshold VAR model allows us to distinguish economic expansion from economic recession and therefore to take into account the variability of the multipliers over time. We couple the TVAR model with the public debt accounting equation in order to "transfer" the effect of a shock from a endogeneous variable to public debt ratio. We then show that a cut in public spending can result in an increase in the public debt ratio in the short term, moreover this effect is significantly higher in recession times. Inversely, an increase in tax revenues lead to a decrease in the public debt ratio, in the short term, whatever the considered regime.

2018-2 "Global Financial interconnectedness: A non-linear assessment of the uncertainty channel" Bertrand Candelon, Laurent Ferrara, Marc Joëts Show Download working paper (on EconPapers) Abstract The role of uncertainty in the global economy is now widely recognized by policy-makers but its effects on the international financial system are less understood. In this paper we assess the impact of uncertainty on the interconnectedness within the international system of equity prices. In this respect, we extend the measure of connectedness put forward by Diebold and Yilmaz (2009) by allowing for non-linear effects through the estimation of a non-linear Threshold VAR model whose regimes depend on the level on uncertainty. Results clearly show that high uncertainty tends to generate more connectedness among equity indexes of a set of advanced and emerging countries. From an economic policy point of view, this result suggests that in the presence of high uncertainty, an adverse financial shock in a specific country is likely to propagate more widely and more strongly to the whole financial system. This result advocates for a close real-time monitoring of uncertainty measures.

2018-3 "Upward Price Pressure in Two-Sided Markets: Incorporating Feedback Effects" Andreea Cosnita-Langlais, Bjørn Olav Johansen, Lars Sorgard Show Download working paper (on EconPapers) Abstract In two-sided markets it is important to consider feedback effects following a merger, i.e. how a price change on one side of the market affects the price change on the other side of the market. Affeldt et al. (2013) introduced the Upward Pricing Pressure (UPP) for two-sided markets, and we extend their approach to take into account such feedback effects. We then discuss the implications of our results for the assessment of two-sided mergers.

2018-4 "Impact du financement par fonds de pension sur la performance des entreprises du CAC 40." Pierre Durand Show Download working paper (on EconPapers) Abstract As pension saving managers, pension funds are able to finance long term investment, R&D and innovation while assuring their role as traditional institutional investors (activism, outsourcing of internal management bias...). As such pension funds can play a crucial role in the French investment dynamic which is mostly characterized by the use of credit. However, among the studies on the influence of institutional investors, few are those specifically interested in pension funds, and none focuses on the French case. This article aims to fill this gap in the literature by studying the impact of pension fund investments of CAC 40 firms' performance. Our results, over the period 2004-2016, highlight a negative influence of pension funds' participation. We explain those findings by the weakness of pension funds' participation and their foreign origin.

2018-5 "Monetary Policy and Asset Price Bubbles" Christophe Blot, Paul Hubert, Fabien Labondance Show Download working paper (on EconPapers) Abstract This paper assesses the linear and non-linear dynamic effects of monetary policy on asset price bubbles. We use a Principal Component Analysis to estimate new bubble indicators for the stock and housing markets in the United States based on structural, econometric and statistical approaches. We find that the effects of monetary policy are asymmetric so the responses to restrictive and expansionary shocks must be differentiated. Restrictive monetary policy is not able to deflate asset price bubbles contrary to the “leaning against the wind” policy recommendations. Expansionary interest rate policies would inflate stock price bubbles whereas expansionary balance-sheet measures would not.

2018-6 "Market Efficiency and Optimal Hedging Strategy for the US Ethanol Market" Emmanuel Hache, Anthony Paris Show Download working paper (on EconPapers) Abstract The aim of this paper is to study the ethanol price dynamics in the US market and find the optimal hedging strategy. To this end, we first attempt to identify the long-term relationship between ethanol spot prices and the prices of futures contracts on the Chicago Board of Trade (CBOT). Then, we model the short-term dynamics between these two prices using a Markov-switching vector error correction model (Ms-VECM). Finally, accounting for the variance dynamics using a Gjr-MGarch error structure, we compute a time-varying hedge ratio and determine the optimal hedging strategy in the US ethanol market.

2018-7 "Contribution de l’immigration à la demande des biens et services finaux en France" Ndeye Penda Sokhna Show Download working paper (on EconPapers) Abstract An argument often put forward when mentioning the positive effects of immigration for the host country is that the entry of immigrants would have positive effects on demand and therefore on growth. This paper aims to measure the contribution of immigrants to the demand for final goods and services in France (over a relatively long period 1979-2011). We conduct an accounting analysis using three main sources of data : family budget surveys from 1979 to 2011, population censuses data and national accounts data. We find that at any age, an immigrant consumes on average less than a native. However, the share of immigrants’ demand in total demand is between 7.3% and 8.3%, which is proportional to their size in the French population. We show that the age structure of the immigrant population (over-represented in the working age group where consumption is at its maximum level) allows for compensation. A disaggregation of total consumption by item shows that immigrants have some specific characteristics : they lead to an increasing in the demand in some expense items such as food, clothing, housing and communication. The analysis of the evolution of consumption shows that between 4.5% and 16% of this change is explained by the immigrant population. However, these changes are more often explained by an increase in the population than by an increase in individual consumption, and this for our two subpopulations.

2018-8 "Is there a market value for energy performance in a local private housing market? An efficiency analysis approach" Catherine Baumont, Frédéric Lantz, Déborah Leboullenger Show Download working paper (on EconPapers) Abstract This paper aims to find evidence of a “green value” in a local housing market using notarial data on a small urban area in France. We use frontier functions, an original approach that departs from customary hedonistic regressions, to model housing market prices as a production set bordered by an efficiency frontier estimated by Data Envelopment Analysis (DEA). The paper tests if difference in prices (i.e. the distance from the frontier) can be explained by energy performance measured as a normalized categorical ascending kWh/m²/year grade (or Energy Performance Certificate -EPC). We show that there is significative evidence for energy performance's market value. The “Green Property Value” is estimated to range between 1% and 3% of the price for medium-high performance buildings. Our findings are robust to the specifications of the first (frontier estimation) and the second stage (residual analysis). We then propose a cost-benefit analysis to evaluate the return on retrofit investment a household would get from higher market value. We find that housing green property value accounts for a part, between 4.6% in houses and 6.6% in collective dwellings, of the real terms investment in energy retrofit. We interpret our findings with regard to spatial dependencies that affect the market and the heterogeneity between the private and the public social housing stocks.

2018-9 "Regional Integration: Do intra-African trade and migration improve income in Africa?" Blaise Gnimassoun Show Download working paper (on EconPapers) Abstract Regional integration in Africa is a subject of great interest, but its impact on income has not been studied sufficiently. Using cross-sectional and panel estimations, this paper examines the impact of African integration on real per capita income in Africa. To do this, we consider intra-African trade and migration flows as quantitative measures reflecting the intensity of regional integration. In order to address the endogeneity concerns, we use a gravity-based IV strategy. Our results show that, from a long-term perspective, African integration has not been strong enough to generate a positive, significant and robust impact on real per capita income in Africa. However it appears to be significantly income-enhancing in the short term but only through inter-country migration. These results are robust to a wide range of specifications. Further analysis shows that economic diversification, financial development and the quality of transport and telecommunication infrastructure significantly affect the impact of intra-African trade on per capita income. Their improvement would make intra-African trade income-improving. Our policy recommendations have been formulated in this direction. Classification-JEL E64, F14, F22, F15, O55.

Julien, Simone Tonin Show Download working paper (on EconPapers) Abstract We consider a bilateral oligopoly version of the Shapley window model with large traders, represented as atoms, and small traders, represented by an atomless part. For this model, we provide a general existence proof of a Cournot-Nash equilibrium that allows one of the two commodities to be held only by atoms. Then, we show, using a corollary proved by Shitovitz (1973), that a Cournot-Nash allocation is Pareto optimal if and only if it is a Walras allocation.

2018-11 "L'INTEGRATION DE L'UEMOA EST-ELLE PRO-CROISSANCE ?" Blaise Gnimassoun Show Download working paper (on EconPapers) Abstract Economists are divided on the effect of exchange rate regimes on economic growth. In this article we study the particular case of the West African Economic and Monetary Union (WAEMU), which is one of the oldest monetary unions in the world resulting from French colonization. The objective is to study the impact of this integration on the economic growth of the region. To this end, we propose an empirical model of economic growth specific to the zone. We also address the problem of simultaneity bias between integration and growth relying on a gravity-based IV strategy. Our econometric results show that although West African regional integration is one of the most important in Africa, it has not led to significant economic growth in the Union. We propose measures to strengthen community transport infrastructures, which are essential to boost integration and its impact on the growth of We propose a massive investment plan in the community transport infrastructure, which is essential to strengthen integration and its impact on the growth of the area.

2018-12 "Credit risk of foreign bank branches and subsidiaries in Argentina and Uruguay" Michael Brei, Carlos Winograd Show Download working paper (on EconPapers) Abstract The paper presents both theoretical and empirical analysis to explain the differences in credit risks between branches and subsidiaries of foreign banks. Using a model with costly monitoring and asymmetric information (from the perspective of host country regulators and parent banks), we show theoretical evidence that the optimal amount of monitoring increases with the size of foreign affiliates (relative to their parent banks), regardless of whether their legal form is of a branch or subsidiary. In the case of small affiliates, we argue that there is a conflict of interest between parent banks and regulators, the former of which prefer to operate with riskier and ring-fenced subsidiaries, and the latter of which prefer better-monitored and co-insured branches. Using bank-level data on Argentina and Uruguay prior to their financial crises of 2001-02, we find that (i) larger foreign branches have lower ratios of non-performing loans than foreign subsidiaries and smaller branches and (ii) branches headquartered in more developed economies had fewer non-performing loans.

2018-13 "Politique monétaire et stabilité financière" Anne-Marie Rieu-Foucault Show Download working paper (on EconPapers) Abstract Trois positionnements théoriques de la politique monétaire par rapport à la stabilité financière sont proposés : assurer le bon fonctionnement des canaux de transmission, utiliser la stabilité financière pour la stabilité des prix et définir un objectif de stabilité financière pour les politiques monétaires. Le premier positionnement relève de la politique de liquidité, qui est naturellement dévolue aux banques centrales. Les deux autres positionnements relèvent d’une politique de solvabilité car prenant en compte la croissance du crédit, les prix d’actifs et l’évolution du cycle financier. Dans ces deux derniers cas, la politique de solvabilité qui n’est pas naturellement dévolue à la banque centrale ouvre un questionnement sur l’absence d’indépendance entre politique monétaire et stabilité financière. Que la stabilité financière soit analysée du point de vue de la stabilité des prix, des mesures non conventionnelles ou des politiques macroprudentielles, le débat sur l’indépendance des deux politiques reste non tranché. A l’heure actuelle, le choix a été fait de ne pas modifier le mandat des banques centrales. Des conséquences sur la politique budgétaire pourraient autrement en résulter.

2018-14 "Multivariate Periodic Stochastic Volatility Models: Applications to Algerian dinar exchange rates and oil prices modeling" Nadia Boussaha, Faycal Hamdi, Saïd Souam Show Download working paper (on EconPapers) Abstract The contribution of this paper is twofold. In a first step, we propose the so called Periodic Multivariate Autoregressive Stochastic Volatility (PV ARSV) model, that allows the Granger causality in volatility in order to capture periodicity in stochastic conditional variance. After a thorough discussion, we provide some probabilistic properties of this class of models. We thus propose two methods for the estimation problem, one based on the periodic Kalman filter and the other on the particle filter and smoother with Expectation-Maximization (EM) algorithm. In a second step, we propose an empirical application by modeling oil price and three exchange rates time series. It turns out that our modeling gives very accurate results and has a well volatility forecasting performance. Classification-JEL C32, C53, F31, G17.

2018-15 "The role of exchange rate undervaluations on the inflation-growth nexus" Florian Morvillier Show Download working paper (on EconPapers) Abstract The link between exchange rate undervaluations and growth has been an important source of concern over the past years, but the role of undervaluations on the inflation-growth nexus has not been yet studied. We fill up this gap by showing to what extent undervaluation's level change the effect of inflation on growth. Our analysis is based on a sample of 62 countries over the period 1980-2015. In a first time, we rely on the Bayesian Model Averaging (BMA) methodology to select the relevant growth determinants. Then, using the System Generalized Method of Moments (GMM), we find evidence that higher is the lagged undervaluation, higher is the negative effect of inflation on growth. This result is robust to the exclusion of currency crises episodes. Classification-JEL F41, O47, E31 Mot(s) clé(s) Exchange rate undervaluation, Inflation, Growth, GMM File
2018-16 "THE DIASPORA AND ECONOMIC DEVELOPMENT IN AFRICA" C. John Anyanwu, Blaise Gnimassoun Show Download working paper (on EconPapers) Abstract While the dominant collective belief asserts that brain drain is detrimental to the development of small economies, new studies hold the reverse view. This paper aims at studying the role of the African Diaspora in the economic development of Africa. It analyzes both the overall effect and the specific effect of emigration according to the level of education of emigrants. Then, through a deeper investigation, the paper analyzes the main channels through which the Diaspora influences economic development in Africa. The results show that the African Diaspora contributes positively, significantly and robustly to the improvement of real per capita income in Africa. These findings challenge the dominant collective belief since the higher the educational level of the emigrants, the greater the impact of the Diaspora on the level of economic development. Improvements in human capital, total factor productivity and democracy are effective transmission channels of this impact. Finally, the results show that while high-skilled emigrants have an overall greater impact on economic development and democracy, those with a low level of education contribute more to remittances to Africa. The establishment of an annual African Diaspora Summer School (ADSS) by the AfDB in partnership relevant international and regional stakeholders as a channel for the transfer of knowledge, technology and experience would further strengthen the role of the Diaspora in Africa’s economic development.

2018-17 "Imperfect Governance and Price Stickiness in Emerging Economies" Zouhair Aït Benhamou Show Download working paper (on EconPapers) Abstract Imperfect governance exacerbates macroeconomic fluctuations in emerging economies. We use strategic interactions between public and private goods to link price stickiness and institutional failure. The government as a provider of public goods exhibits agency in its relationship with households, and that yields to welfare losses for the latter. The government also faces a sub-optimal Laffer curve because of its inability to extract taxes. Imperfect governance also has an impact on terms of trade, as it distorts domestic prices in comparison to those of imported goods.

2018-18 "Oil windfalls might not be the problem in oil-producing countries: evidence from the impact of oil shocks on export diversification" Eric W. Djimeu, Luc-Désiré Omgba Show Download working paper (on EconPapers) Abstract This paper examines the factors behind export diversification in oil countries. Specifically, by investigating the impact of oil booms on export diversification through a difference-in-difference framework, this paper finds that the economy’s export structure before oil boom determines whether oil windfalls might affect the diversification process. Thus, an oil boom negatively affects export diversification only if countries initially exhibit low levels of diversification. In countries with a high level of diversification before the boom, an oil boom has no impact on diversification. These results are based on a large sample of 134 countries, and are robust to various sensitivity analyses. They are corroborated with data from the manufacturing sector, which show that oil booms only reduce diversification in countries with a small manufacturing sector prior to the boom. The results suggest that the initial constraints, which hampered the emergence of entrepreneurs’ class prior the boom, are key elements of the failure of a diversification process in resource rich countries.

2018-19 "The quantification of structural reforms: extending the framework to emerging market economies" Balázs Egert Show Download working paper (on EconPapers) Abstract This paper estimates and quantifies the impact of structural reforms on per capita income for a large set of OECD and non-OECD countries. The findings suggest that the quality of institutions matters to a large extent for economic outcomes. More competition-friendly regulations, as measured by the OECDs’ Product Market Regulation (PMR) indicator improve economic outcomes. Lower barriers to foreign trade and investment help MFP. Lower barriers to entry and less pervasive state control of businesses boost the capital stock and the employment rate. No robust link between labour market regulation and MFP and capital deepening could be established. But looser labour market regulation is found to go hand in hand with higher employment rates. The paper shows that countries at different level of economic development face different policy impacts. Furthermore, PMR effects depend on the level of labour market regulations.

2018-20 "Aggregate multi-factor productivity: measurement issues in OECD countries" Balázs Egert Show Download working paper (on EconPapers) Abstract This paper analyses for 34 OECD countries the extent to which the calculation of aggregate multi-factor productivity (MFP) is sensitive to alternative parameterisations. The starting point is the definition of MFP used in previous work in the OECD’s Economics Department (e.g. Johansson et al. 2013). They include alternative MFP measures, with human capital included or excluded, with different measures of Purchasing Power Parity (PPP) exchange rates, using time-varying capital depreciation rates and different measures of capital stock and labour input (headcount against hours worked). The main result of the paper is that whether or not human capital is included in MFP makes a significant difference for the level and dynamics of MFP. At the same time, MFP measures are less sensitive to other parameters of the calculation. Classification-JEL O4 Mot(s) clé(s) multi-factor productivity, measurement, human capital, OECD File
2018-21 "Can Public and Private Sanctions Discipline Politicians? Evidence from the French Parliament" Maxime Le Bihan, Benjamin Monnery Show Download working paper (on EconPapers) Abstract This paper investigates the effects of sanctions on the behavior of deputies in the French National Assembly. In 2009, the Assembly introduced small monetary sanctions to prevent absenteeism in weekly standing committee meetings (held on wednesday mornings). Using a rich monthly panel dataset of parliamentary activity for the full 2007-2012 legislature, we study the reactions of deputies to (i) the mere eligibility to new sanctions, (ii) the actual experience of a salary cut, and (iii) the public exposure of sanctioned deputies in the media. First, our diff-in-diff estimates show very large disciplining effects of the policy in terms of committee attendance, and positive or null effects on other dimensions of parliamentary work. Second, exploiting the timing of exposure to actual sanctions (monthly salary cuts versus staggered media exposure), we find that deputies strongly increase their committee attendance both after the private experience of sanctions and after their public exposure. These results suggest that monetary and reputational incentives can effectively discipline politicians without crowding out intrinsic motivation.

2018-22 "Understanding the long run dynamics of French unemployment and wages" Michel-Pierre Chélini, Georges Prat Show Download working paper (on EconPapers) Abstract A standard specification of the WS-PS model based on wage bargaining between unions and firms makes it possible to understand the main features of long-term dynamics of unemployment and wages in France at the macroeconomic level. This result is conditional on auxiliary hypotheses made on the representations of the degree of rigidity in the labour market (depicted by a stochastic state variable), of the reservation wage (depending on the legal minimum wage), and on the nature of “other factors” pertaining to wages and prices that are not a priori specified in the WS-PS theoretical framework (summarized by the output gap). We find that the observed unemployment adjusts gradually to its equilibrium value, which is composed of three components: a “chronic” component due to the repartition in the added-value (real reservation wage, social contributions, productivity, profit margins of companies), a “cyclical” component depending on the output gap, and a “frictional” component due to the imperfect mobility of labour and technical progress. The observed wage also adjusts gradually to its negotiated value, the latter depending on the reservation wage, the social contributions, the price level, the labor productivity, the profit margins of companies, the unionization rate and on the unemployment rate whose influence is time-varying. Our results suggest that, in the average, the power of firms dominates that of unions during the negotiations, while, as predicted by the theory, change in employment intervenes effectively in the adjustment between wage desired by employees and wage offered by employers to achieve equilibrium.

2018-23 "Term structure of bank flows to emerging countries: what effects of short- vs. long-term regulatory arbitrage are?" Samira Hellou Show Download working paper (on EconPapers) Abstract Considering the literature of economic stability, the need to analyze short-term external bank flows is particularly obvious to prevent the contagion crisis. Moreover, the context of crisis has put prudential regulation at the center of the current debate in this literature. In this paper, we offer a new perspective on the role of regulation as a determinant of banking flows maturity, with a focus on the issue of short-term vs. long-term regulatory arbitrage. Indeed, regulatory arbitrage that favors short-term bank flows is a destabilizing factor of the financing of these countries as they have experienced major crises due to the external financing volatility. We adopt a macroeconomic approach to study the importance of bank regulation adjustments as a determinant of bank flows maturity from 12 developed countries to 37 emerging countries for the period 1990-2014. The results confirm the significant effect of risk-based regulation on the term structure of bank flows to emerging countries, especially to speculative countries. Classification-JEL F32, F34, G28.

2018-24 "The tale of two international phenomena: International migration and global imbalances" Dramane Coulibaly, Blaise Gnimassoun, Valérie Mignon Show Download working paper (on EconPapers) Abstract Following the dynamics of globalization, international migration has increased dramatically since the 1990s. Given that these migrations may obscure the natural demographic structure of nations, they are likely to explain a significant part of global imbalances. This paper tackles this issue by investigating the role played by international migration in the dynamics of global imbalances. To this end, we rely on an overlapping generations model to derive the theoretical relationship between international migration and current account position. Through a series of robust estimates, we empirically investigate this relationship by relying on a panel of 157 developed and developing countries over the period 1990-2014. Our results point to substantial effects of international migration. Specifically, we show that an increase in migration improves national savings and the current account balance in the destination country, while it has opposite impacts in the origin country. These effects are particularly pronounced in developing economies, and attenuated by migrants' remittances.

2018-25 "Term structure of interest rates: modelling the risk premium using a two horizons framework" Georges Prat, Remzi Uctum Show Download working paper (on EconPapers) Abstract This paper proposes a hybrid two-horizon risk premium model with one- and two-period maturity debts, among which the risky asset and the riskless one depend on agents’ investment horizon. A representative investor compares at each horizon the ex-ante premium offered by the market with the value they require to take a risky position, with the aim of choosing between a riskless and a risky strategy. Due to market frictions, the premium offered adjusts gradually to its required value determined by the portfolio choice theory. The required market risk premium is defined as a time-varying weighted average of the required 1- and 2-period horizon premia, where the weights represent the degree of preference of the market for each of the horizons. Our framework is more general than the standard model of the term structure of interest rates where it is assumed that the 1-period rate is the riskless rate at any time and for all agents. Setting one period equal to three months, we use 3-month ahead expected values of the US 3-month Treasury Bill rate provided by Consensus Economics surveys to estimate our 3- and 6-month horizon risk premium model using the Kalman filter methodology. We find that both 3- and 6-month maturity rates represent the riskless and the risky rates with a time-varying market preference for the former rate of about two-thirds. This result strongly rejects the standard model and shows the importance of taking into account the market preference for alternative horizons when describing risky strategies in interest rate term structure modelling.

2018-26 "The Nonlinear Relationship between Economic growth and Financial Development" Balázs Egert, Fredj Jawadi Show Download working paper (on EconPapers) Abstract This paper studies the relationship between financial development and economic growth in a large sample of developing, emerging and advanced economies and on a separate, longer sample including only OECD countries over the recent period. Estimation results based on nonlinear threshold regression models do not confirm the too-much-finance-is-bad hypothesis, especially if the cross-country variation in the data is accounted for. We cannot indeed identify a tipping point beyond which financial development has a negative relation to economic development. What we see at best is that the positive effect of finance declines at higher levels of finance. Our results also show that banking and market finance are complementary. The positive effect of stock market deepening is larger when banking finance is more pronounced (and the other way around). But the thresholds above which complementarity kicks in are rather low. Finally, our results indicate that finance has a stronger positive effect in more developed countries. At the same time, the positive effect of finance is weaker in countries with lower trade openness. This may suggest that more open economies have access to alternative sources of external financing.

2018-27 "CREDIT RISK AND BANK COMPETITION IN SUB-SAHARAN AFRICA" Michael Brei, Luc Jacolin, Alphonse Noah Show Download working paper (on EconPapers) Abstract This paper investigates the impact of bank competition in Sub-Saharan Africa on bank non-performing loans, a measure of credit risk. Using bank-level data for a sample of 221 banks from 33 countries over the period 2000-15, we find a non-linear or U-shaped relationship between bank competition and credit risk. In other words, increased bank competition has the potential to lower credit risk via efficiency gains (lower credit cost, operational gains). However, the positive effects may be outweighed by adverse effects of excessive competition (lower profit margins, increased risk incentives). We also find that credit risk in Sub-Saharan Africa is not only related to macroeconomic determinants, such as growth, public debt, economic concentration, financial deepening and inclusion, but also to the business and regulatory environment. These results may provide useful insights on how to design and adapt prudential and regulatory frameworks to the specific needs in developing countries.

2018-28 ""Taking Diversity into Account": Real Effects of Accounting Measurement on Asset Allocation" Gaëtan Le Quang Show Download working paper (on EconPapers) Abstract Following a request made by the G20, the IASB begins to work in 2009 on a new accounting standard meant to replace IAS 39: IFRS 9. Among other things, IFRS 9 puts forward a new way of classifying financial instruments that rests on a two-step procedure: a business model assessment and a contractual cash flow characteristics test. We develop a theoretical model that assesses the relevance of this procedure, specifically that of the business model assessment. We show that a mixed accounting regime where financial institutions whose time horizon is short resort to fair value accounting while those whose time horizon is longer resort to historical cost accounting provides a better asset allocation than a pure accounting regime where all FIs resort to the same accounting rule. In other words, business models are worth being taken into consideration when deciding whether an asset should be evaluated at its fair value or at its historical cost, which is in line with the framework presented in IFRS 9.

2018-29 "Media Perception of Fed Chair's Overconfidence and Market Expectations" Hamza Bennani Show Download working paper (on EconPapers) Abstract This paper aims to assess the impact of media perception of Fed chair's overconfidence on market expectations. We first use a media-based proxy to compute a measure of Fed chair's overconfidence for the period 1999M01-2017M07, the overconfidence indicator. The overconfidence indicator provides a measure of the perceived overconfidence of the Fed chair by the media, and thus, by financial market participants. We relate this variable to inflation and unemployment expectations of market participants. Our results show that an overconfident Fed chair is associated with higher inflation expectations and lower unemployment expectations. These findings are robust to (i) the macroeconomic forecasts used to extract the exogenous component of the media-based proxy reflecting Fed chair's overconfidence, (ii) different measures of the media-based proxy used to quantify Fed chair's overconfidence and (iii) different measures of inflation expectations. These findings shed some new light on the impact of central bankers' personality on market expectations, and thus, on the effectiveness of their monetary policy decisions.

2018-30 "The eﬀects of migration and pollution externality on cognitive skills in Caribbean economies: a Theoretical analysis" Lesly Cassin Show Download working paper (on EconPapers) Abstract Caribbean Small Island Developing States (SIDS) face speciﬁc social, economic and environmental vulnerabilities. This paper provides a simple overlapping generations model with migration and intergenerational transfers in an economy where production generates pollution. This pollution hampers the cognitive skills of the children and thus the eﬃciency of human capital accumulation in the economy. Therefore the model developped in this work introduces kea features of Caribbean SIDS in order to exacerbate the dynamics between demography – i.e. migration and human capital accumulation – and pollution. Results reveal that the usual gain from migration in terms of human capital was no longer possible because of the environmental externality. Indeed, in most of the cases, in presence of the environmental externality, per capita variables (utility, production and capital) are decreased by migration, while the aggregated production can be enhanced thanks to the demographic growth that occurs with migration. Moreover, it has been shown that the conditions to have a proﬁtable environmental tax depend on the pollution intensity of the economy. Finally, the interactions between the emigration rate and the form of intergenerational transfers – i.e. solidarity from the domestic area and/or from the diaspora – have an impact on the scale of the reduction of human capital due to migration. Thus, in this model a gain from an increase in the rate of emigration is still possible but only if migration is already very high.

2018-31 "Les interventions de crise de la FED et de la BCE diffèrent-elles ?" Anne-Marie Rieu-Foucault Show Download working paper (on EconPapers) Abstract In the context of the 2007-2009 financial crisis, central banks innovated in the form of multiple unconventional measures. Due to a different history, different mandates and monetary policy implementations, the first crisis measures, mainly for financial stability, differed between the Fed and the ECB, resulting in a balance sheet size and structure of the assets specific to each. After 2015, the ECB's large-scale asset purchase transactions marked a convergence of the unconventional policies of the two central banks, which resulted in the ECB renouncing the principle of separation between monetary policy and stability financial. In addition, the risk-taker of last resort function of the two central banks has increased, although differences persist in their risk management policies (scope of counterparties and securities eligible).

2018-32 "Male reproductive health, fairness and optimal policies" Johanna Etner, Natacha Raffin, Thomas Seegmuller Show Download working paper (on EconPapers) Abstract Based on epidemiological evidence, we consider an economy where agents differ through their ability to procreate. Households with impaired fertility may incur health expenditures to increase their chances of parenthood. This health heterogeneity generates welfare inequalities that deserve to be ruled out. We explore three different criteria of social evaluation in the long-run: the utilitarian approach, which considers the wellbeing of all households, the ex-ante egalitarian criterion, which considers the expected well-being of the worst-off social group, and the ex-post egalitarian one, which only considers the realized well-being of the worstoff. In an overlapping generations model, we propose a set of economic instruments to decentralize each solution. To correct for the externality and inequalities, both a preventive (a taxation of capital) and a redistributive policy are required.

2018-33 "Dynamic Effects of the Chilean Fiscal Policy" Antonio Lemus Show Download working paper (on EconPapers) Abstract In Chile, the empirical literature studying the dynamic effects of fiscal policy and fiscal multipliers, using linear vector autoregression models, disagrees on the effects of government spending and taxes on output. In this paper, we bring new elements to this debate. We include the nonlinear dimension of vector autoregression models to answer if the state, “tight” or “normal”, of the Chilean economy, affects fiscal policy effectiveness. Last, based on the nonlinear framework we question if monetary policy has an influence on the size of fiscal multipliers. We find that: (i) once using the same quarterly data, the size of fiscal multipliers not only varies depending on the identification strategy and the linear vector autoregression model used but also on the definitions of government spending and taxes considered; (ii) the government spending multiplier from the nonlinear framework differs, being about the unit in the “tight” regime and around -0.5 in the “normal” regime; (iii) government spending and tax multipliers in the nonlinear framework are smaller when monetary policy is taken into account, which influences the effectiveness of fiscal policy.
