Titre / title «  Do common standards promote competition ? A market experiment  »
Co-authored with Paolo Crosetto - INRA UMR 1215, GAEL, Université de Grenoble
Abstract/Résumé We run a market experiment where firms can choose not only their price but also whether to adopt a common standard. Common stan­ dard offers are favored by a portion of the consumers. We vary the proportion and strength of preferences for the common standard of this portion of consumers, and find divergent effects in treatments with full information about competitors and in those with no infor­ mation. In treatments with full information, early phases with strong competition and frequent adoption of a common standard are fol­ lowed by later phases with frequent collusion. Firms appear to un­ derstand the benefit of not adopting the common standard and are able to collude in doing so. In treatments with no information how­ ever, firms are led to adopt the common standard more often as the portion of savvy consumers increases, which leads to an improvement in welfare for ail consumers.

Titre / title «  The Comparative Effects of Independence on Trade  »
Co-authored with Emmanuelle Lavallée - Université Paris-Dauphine
Abstract/Résumé Empirical evidence suggests that belonging to an empire favours trade by lowering transaction costs and establishing preferential trade agreements. Does the end of an empire invert this effect, and if so, through which channels ? This paper uses an original dataset to explore the impact of independence on former colonies’ bilateral trade over the 1948-2007 period. We show large differences across empires. Whereas independence reduces trade (imports and exports) of former French colonies with their former coloniser and with other colonies of the same empire, we do not fi-nd any comparable effect for former British colonies. We attribute this -nding to the particularly protectionist trade policy implemented by France during the colonial era and we are able to rule out alternative explanations related to transaction costs. We also -nd that after independence, all former colonies trade more with third countries and we relate this result to the geographical diversi-cation of trade.

Titre / title «  Environmental taxation, health and the life-cycle  »
Co-authored with Nathalie Mathieu-Bolh - University of Vermont (USA)
Abstract/Résumé We build a model that takes into consideration the evolution of health over the life cycle and its consequences on individual optimal choices. In this framework, the effects of environmental taxation are not limited to the traditional negative crowding-out and positive productivity effects. We show that environmental taxation generates new general equilibrium effects ignored by previous contributions. Indeed, as the environmental tax improves the health profile over the life-cycle, it influences saving, labor supply, and retirement. We also show that whether those general equilibrium effects are positive or negative for the economy crucially depends on the degree of substitutability between young and old labor. Our numerical examples suggest that ignoring those new effects may result in large overstatement of the negative effect of an increase in environmental taxation on output, and understatement of the positive effect on welfare.

Titre / title «  Differential Taxation and Occupational Choice  »
Co-authored with Renato Gomes and Alessandro Pavan
Abstract/Résumé We study nonlinear income taxation in a Roy model in which agents’ productivity is sectorspecific. Our main result shows that when di↵erential taxation is possible (that is, when income taxes can be sector-specific), the celebrated Diamond-Mirrlees theorem (according to which the second-best displays production efficiency) fails : total output can be increased by reassigning the agents to teh two sectors, while keeping their labor supply constant. By sacrifying production efficiency, a benevolent government maximizing either a Rawlsian or a Concave Utilitarian welfare objective obtains a first-order reduction in the incentive costs of redistribution. The same result obtains when the government is constrained to a uniform income tax schedule, as long as sales taxes can be made sector-specific. In this latter case, our result also implies failure of the celebrated Atkinson-Stiglitz theorem (according to which, when preferences over consumption and leisure are separable, as they are in our economy, the second-best can be implemented with zero sales taxes).

Titre / title «  Credit and Bubbles  »
Résumé/Abstract This paper is based on a production economy, where the capital of firms is composed of equity and debt. Firms face stochastic investment opportunities, and their debts are secured by the market price of the equity of the firms. We show in this paper how credit constraints and investment opportunities generate different prices of firms. One pricing corresponds to the case where the Tobin’s Q is one, and the market value correponds to the book value. In the other case, the Tobin’s Q is larger, and the market value is larger. This allows firms with low amounts of capital to relax credit constraints. We show that price of firms may be bubbly, though this situation is rare. Finally, we test the effect of interest rate shocks on the value of firms, especially on their ability to generate crashes on market prices.

Titre / title «  The role of supply and information in the long tail effect : an experimental study  »
Co-authored with Fabrice Le Lec (Université de Paris 1 et CES)
Co-authored with Marianne Lumeau (University of Paris 13, CEPN and LABEX ICCA)
Résumé/Abstract Recent studies have shown that the development of online markets may generate a long tail for cultural goods (Anderson, 2006) : whereas offline demand is highly concentrated on few popular goods (or superstar products), online demand is less concentrated benefiting to niche products. This paper aims at explaining the origin of the emergence of the long tail effect by disentangling two of its possible origins : the high number of goods available online (or supply effect) and the opportunity to easily find information (or information effect). For this purpose, we use an experimental approach for which subjects have to choose an experience good. We compare six experimental treatments differing with respect to the size of the choice set and the size of the information set. Our experimental results show that subjects tend to choose more niche products in treatments with a small choice set than in treatments with a large choice set. This result seems to indicate a choice overload effect among our subjects. Concerning the information effect, we observe that subjects choose more niche products in treatments with a high level of information than in treatments with a low level of information. Altogether, these results indicate that the long tail effect seems to be mainly explained by the opportunity to easily find information online, rather than the increase of the number of products available.

Titre / title «  Financial Stability and Economic Performance  »
Co-authored with Jérôme Creel, Paul Hubert
Abstract/Résumé This paper aims at establishing the link between economic performance and financial stability in the European Union from 1998 to 2011. We use the standard framework – both in terms of variables and econometric method – of Beck and Levine (2004) to estimate this causal relationship, independently from but controlling for the level of financial depth. We test how different measures of financial instability (an institutional index, microeconomic indicators, and our own statistical index derived from a Principal Component Analysis) affect economic performance (or components of aggregate dynamics like consumption, investment or disposable income) and find that financial instability has a negative effect on economic growth. Our results also suggest that the traditional result that financial depth positively influences economic performance is not confirmed for a subset of advanced economies like European countries.

Titre / title «  Do Environmental Policies Hurt Trade Performance ?  »
Co-authored with Jean-Louis Combes, Somlanare Romuald Kinda
Abstract/Résumé This paper contributes to the controversial literature on the relationship between environmental policies and international trade. It provides new evidence about the effect of a gap in environmental policies between trading partners on trade flow on a sample of developed and developing countries over the 1980-2010 period. The paper innovates on two aspects. First, while previous studies have used partial measures of environmental regulations (input-oriented or output-oriented indicators), an ndex of a country’s environmental policy is computed. This index is calculated as the difference between observed pollution levels and “structural” pollution i.e. pollution predicted by determinants of environmental degradation as identified and modelled in the literature. This index is therefore a measure of “revealed” efforts made by countries aiming at downsizing environmental degradation. Second, the effect of these revealed environmental policies is assessed on bilateral trade flows in a gravity model. A particular attention is paid to similarities in environmental policies. Our results show that a gap in domestic efforts towards environmental protection between trading partners has no effect on exports. Moreover, the results do not appear to be conditional on the level of development of the countries rading or on the characteristics of exported goods (manufactured goods and primary commodities).

Titre / title «  Time–Aggregation Effects on Estimating Asset Pricing Models  »
Co-authored with Nour Meddahi - Toulouse School of Economics
Abstract/Résumé The main goal of the paper is to characterize the impact of temporal aggregation on the estimation of the preference’s parameters of a representative agent in a consumption based asset pricing model (CCAPM).We assume that the true economy is at a high frequency (say monthly), that is we model the endowments and the preference of the representative agent and then we characterize the asset prices at the high frequency. We then assume that the econometrician observes data at a lower frequency (say annual) and he postulates a model for the endowments and the preferences at the high frequency and he uses the data (implied by the high frequency economy) to estimate the parameters of the model at the low frequency. We are then able to characterize the mapping between the preference’s parameters at low frequency with those at high frequency. The mapping is analytical in many examples. The model is misspecified at a low frequency, therefore the estimated parameters will depend on the statistical method and the moments that are matched. We therefore follow the CCAPM literature by focusing on matching the means of the risk free rate and the excess returns.

Titre / title «  The Political Economy of Renewable Energies  »
Co-authored with Fabio Padovano - CREM, Université Rennes 1 - Condorcet Center for Political Economy - DIPES, Università Roma Tre
Abstract/Résumé This paper empirically analyzes the determinants of renewable energy (RE) deployment, in the sample of the EU countries that are bound to increase their share of RE in gross final energy consumption by 2020. While we consider a comprehensive set of determinants of the adoption of RE, including economic variables, energy and environmental factors, the focus is on political economy drivers, namely, the quality and ideology of government and on the institutional framework where energy policy decisions are implemented. The panel data analysis shows that economic growth has a positive impact on RE deployment, agricultural sector lobbying a negative one, whereas standard measures of government quality show a positive effect. Finally, left-wing parties promote the deployment of RE more than right wing ones, but this effect is reduced when the governing coalition is highly concentrated. Different specifications and estimation techniques are adopted to check the robustness of the results and the dynamic properties of the estimated relationships.

Titre / title «  Mass consumption and bounded learning by doing : Some demand-side implications of income distribution for growth  »
Co-authored with Fernando Jaramillo - Universidad del Rosario, Bogotá - Colombia
Abstract/Résumé Stylized facts relevant to the analysis of economic growth traditionally focus on the supply-side of the economy. Little reference is made to mass consumption which has accompanied both industrial revolutions, and which today is a key feature of economic development in large emerging countries. This paper provides an endogenous growth model where supply (structural change) and demand (middle class consumption) interact to bring out a multi-industry flying-wild-geese development pattern where each industry may learn from its own experience and/or from others. An industry learning curve is assumed to evolve over time with cumulative industry output which in turn depends on the income distribution. To that end, we relax the assumption of homothetic preferences that neutralizes demand in the long-run. We discuss the implications of income distribution on an industry learning curve in a set up where a society of mass consumption may arise as a consequence of horizontal demand complementarities and technological spillovers across industries. Eventually, the survival function of the income distribution determines each industry learning curve. Only a non-degenerate, i.e. neither perfectly equal nor completely unequal, distribution of income will yield long-run growth. There is an inverted-U relationship between inequality and growth. The rate of growth ultimately depending on the size of the middle class which creates the conditions for mass consumption, scale economies and learning by doing as sources of sustained growth.

Titre / title «  Does bank ownership affect lending behavior ? Evidence from the Euro area  »
Abstract/Résumé We analyze the differences in lending policies across banks characterized by different types of ownership, using micro-level data on Euro area banks during the period 1999-2011 to detect possible variations in bank lending supply responses to changes in monetary policy. Our results identify a general difference between stakeholder and shareholder banks : following a monetary policy contraction, stakeholder banks decrease their loan supply to a lesser extent than shareholder banks. A detailed analysis of the effect among stakeholder banks reveals that cooperative banks continued to smooth the impact of tighter monetary policy on their lending during the crisis period (2008-2011), whereas savings banks did not. Stakeholder banks’ propensity to smooth their lending cycles suggests that their presence in the economy has the potential to reduce credit supply volatility.

Titre / title «  Certifiable Pre-Play Communication : Full Disclosure  »
Co-authored with Frédéric Koessler, Eduardo Perez-Richet
Abstract/Résumé This article asks when communication with certifiable information leads to complete information revelation. We consider Bayesian games augmented by a pre-play communication phase in which announcements are made publicly. We first characterize the augmented games in which there exists a fully revealing sequential equilibrium with extremal beliefs (i.e., any deviation is attributed to a single type of the deviator). Next, we define a class of games for which existence of a fully revealing equilibrium is equivalent to a richness property of the evidence structure. This characterization enables us to provide different sets of sufficient conditions for full information disclosure that encompass and extend all known results in the literature, and are easily applicable. We use these conditions to obtain new insights in games with strategic complementarities, voting with deliberation, and persuasion games with multidimensional types.

Co-authored with Juan Carluccio - Banque de France and Surrey University
Co-authored with Denis Fougère - CNRS, CREST, LIEPP (Sciences Po, Paris), CEPR, IZA and Banque de France
Abstract/Résumé Using French firm-level data on wages, wage bargaining and trade, we study how international trade impacts domestic wages and wage bargaining at the firm level. Using instrumental variables techniques we find that, at the intensive margin, increases in both imports and exports tend to increase wages. The effect of both activities is heterogeneous across workers : exports have a larger effect on wages of blue collar workers whereas the impact of imports is larger for managers. We also explore the role of wage bargaining. We find that increases in the intensive margin of trade lead to a significantly higher probability that a firm-level wage agreement is signed. Furthermore, in firms where a wage agreement is signed, the wage export premium tends to be larger, especially for blue collar workers, whereas the wage import premium is smaller.

Titre / title «  Inflation-Targeting and Foreign Exchange Interventions in Emerging Economies  »
Abstract/Résumé Are emerging economies implementing inflation targeting (IT) with a perfectly flexible exchange-rate arrangement, as developed economies do, or have these countries developed their own IT framework ? This paper offers a new method for assessing exchange-rate policies that combines the use of “indicator countries”, providing an empirical definition of exchange-rate flexibility or rigidity, and clustering through Gaussian mixture estimates in order to identify countries’ de facto regimes. By applying this method to 19 inflationtargeting emerging economies, I find that the probability of those countries having a perfectly flexible arrangement as developed economies do is 52%, while the probability of having a managed float system, obtained through foreign exchange market intervention, is 28%, and that of having a rigid exchange-rate system (similar to those of pegged currencies) is 20%. The results also provide evidence of two different monetary regimes under inflation targeting : flexible IT when the monetary authorities handle only one tool, the interest rate, prevailing in ten economies, and hybrid IT when the monetary authorities add foreign exchange interventions to their toolbox, prevailing in the remaining nine economies.

Titre / title «  On the efficiency of whistleblowing-based audit schemes : An experimental approach  »
Co-authored with Mickael Beaud - LAMETA, Université de Montpellier
Co-authored with Dimitri Dubois - LAMETA, Université de Montpellier
Abstract/Résumé In the extensive literature on tax evasion, considerable efforts have been devoted to the analysis of deterrent policies to fight tax evasion. So far, however, little attention has been paid to tax informants. In this respect, an important question is that of the efficiency of audits targeted using information from whistleblowers. In the present paper, we present a between-subject lab experiment designed to explore the behavior of individuals facing a whistleblowing-based audit scheme and to assert its relative efficiency compared to a standard random audit scheme.The results show that significantly less tax evasion is obtained under the whistleblowing-based audit scheme, because evaders are more efficiently targeted by audits. At the individual level, our main findings can be summarized as follow : (i) two main profiles of taxpayers dominate, (ii) a positive correlation between evasion and whistleblowing, and (iii) players in most cases denounce those who declare less than themselves.

Titre / title of paper «  Beliefs and Ambiguity Attitudes for Natural Sources of Uncertainty  »
Co-authored with Mohammed Abdellaoui - HEC Paris
Co-authored with Han Bleichrodt - Erasmus School of Economics
Co-authored with Emmanuel Kemel - HEC Paris
Abstract/Résumé In many decisions probabilities are unknown and beliefs must be measured. This paper shows how beliefs can be measured. Our method has two advantages over existing methods for measuring beliefs. First, it permits to measure continuous distributions of beliefs and not just beliefs for single events. Second, it is valid under many models of decision under uncertainty, and allows for risk aversion, deviations from expected utility, and ambiguity aversion. For ambiguity models, our method measures not only beliefs but also attitudes towards ambiguity (the confidence decision makers have in their beliefs). We applied our method in an experiment using two natural sources of uncertainty, temperature in Rotterdam and in New York City. As expected, beliefs differed between these two sources of uncertainty and they were well-calibrated. Subjects deviated from expected utility. Twenty percent of our subjects behaved according to expected utility with a utility function that depended on the source of uncertainty. For the remaining 80% of our subjects utility was the same for the two sources of uncertainty, but the weighting of events differed.

Titre / title of paper «  Dynamics of Social Norms in the City  »
Abstract/Résumé We study how in a city either opposite social norms remain or a particular code of behavior spreads and ultimately prevails. We develop a multicommunity model with overlapping generations. When young, an individual chooses the level of educational e§ort. The crucial feature is that her decision is ináuenced by peers living in the area who favor either a social norm valuing education or a social norm discrediting education. When an adult, an individual who cares about her o§springís expected income chooses the familyís location. Endogenous location leads to di§erent patterns of social norms in the city. We identify two types of urban equilibrium : a culturally-balanced city where social norms are distributed evenly among urban areas and the rate of education is the same in each urban area and a culturally-divided city where urban areas oppose on their prevailing social norm and exhibit di§erent rates of education. We then study the dynamics of social norms. We show that there are multiple long-run patterns of social norms. A particular steady state is achieved depending on the initial distribution of social norms support in the population. Finally, we show that the public policies promoting social integration can lead in the long run to a population unanimously discrediting education and getting less education than letting the culturally-divided city arise.

Titre / title of paper «  Measuring competitive imbalance in team sports : toward an axiomatic approach  »
Co-authored with Nicolas Lepape - CREM, Université de Caen Basse-Normandie
Abstract/Résumé Il existe une analogie évidente entre la mesure de l’Imbalance Competitive dans les ligues de sport professionnels et la mesure des inégalités de revenus (ou de salaires), mais, jusqu’à présent, très peu de travaux font référence à une liste de propriétés désirables que devrait respecter tout indice d’Imbalance. Dans cet article, nous proposons des propriétés spécifiques qui, en supplément du socle de propriétés usuelles (Anonymat, Normalisation, Principe des Transferts), permettent de restreindre la classe des indices pertinents pour l’économie du sport. Les propriétés principales sont élaborées sur la base de déplacements de blocs d’équipes en parfait équilibre compétitif au sein de distributions parfaitement hiérarchisées. En matière d’Imbalance–Attractivité, dans une ligue fermée, nous suggérons que l’inégalité est d’autant plus faible que la compétition est féroce entre des équipes de haut de tableau (en comparaison avec une ligue où la compétition serait féroce entre des équipes de bas de tableau). Nous proposons également un postulat propre aux ligues avec Promotion & Relégation. Nous soulevons enfin la question de la transposition de ces axiomes aux raffinements des mesures de concentration en économie industrielle.

Titre / title of paper «  Urban Costs and the Spatial Structures of Cities : A Laboratory Experiment  »
Co-authored with Michel Bliemer, Laurent Denant-Boèmont, David Hensher, Corinne Mulley
Abstract/Résumé This paper presents a laboratory experiment to investigate how urban costs might determine the internal structure of urban areas (monocentric or polycentric) by influencing location choices of firms and households. The experimental design is in part guided by the theoretical model of Cavailhes et al. (2007) that shows how the trade-off between communication costs faced by firms in order to access essential facilities located in the CBD, and commuting costs borne by workers, determine the degree of cities’polycentricism by influencing the distribution of the workplaces within it. In the experiment, groups of 16 subjects participated in a two-step auction game, where firms and workers first negotiated to find a job contract and second where workers bid for land in order to find a home. The game is repeated for four rounds and different experimental treatments are implemented, each defining a given scenario for communication costs and commuting costs. The chosen benchmark is a polycentric city treatment, where no communication cost exists for firms, giving them no incentive to locate in the CBD. In two other treatments, the communication cost is positive. In the Monocentric City treatment, commuting cost for workers is low, giving a clear incentive for firms to locate in the CBD, as workers do not suffer from potential high commuting costs, giving an outcome where all firms should locate in the CBD. In the Hierarchical City treatment, the commuting cost is very high for workers, giving workers a strong incentive to live close to their workplace and accepting lower wages as a result. Experimental results are in line with theoretical predictions : firms tend to locate in the CBD under the monocentric treatment, whereas more distant locations are accepted leading to a hierarchical outcome as workers propose lower wages for not working in the CBD so as to escape high commuting costs.

Titre / title of paper «  The Welfare Effects of Regulating the Number of Market Segments in Linear Demand Markets  »
Abstract/Résumé We consider a model in which the monopolist faces N different markets while the regulator chooses the number k of prices, where k is an integer between 1 and N. The monopolist thus faces a combinatorial optimization problem, the solution of which is called the optimal profit policy. We show that the number of discriminatory prices that maximizes the social welfare is never higher than a threshold k <=> http://crem.univ-rennes1.fr/Documen... ]

Co-authored with Lata Gangadharan - Department of Economics, Monash University
Co-authored with Giancarlo Musto - GATE CNRS University of Lyon
Abstract/Résumé «  In the standard rank-order tournament model, the loser and winner prizes are defined by the principal, and as such they are fixed for the agents. As a consequence, the incentives are based both on the spread between prizes and on the ranking of both individual performances. In contrast, our tournament model designs incentives not only through the ranking and the prize spread, but also through the level of both individual performances : agents should be mindful of what they earn ; being the winner is not enough. At the equilibrium both tournaments result in an efficient allocation of resources. They both elicit the same level of effort and entail the same expected utility. Nevertheless, endogenous prizes give a marginal gain from increasing effort while losing. We use a laboratory experiment to study how both tournament designs influence the motivations of the participants. We use a laboratory experiment to study how both tournament designs influence the motivations of the participants. Participants provide higher effort under a compensation scheme that rewards them with fixed shares of their total production. This positive effect on the provision of effort can be partly explained by the risk structure embodied in the endogenous-prize tournament. Under a standard rank-order tournament, risk aversion - in line with the theory - reduces the provision of effort. Instead, in the endogenous-prize tournament, risk aversion tends to increase the provision of effort.  »

Titre / title of paper «  Evaluating the law of one price using micro panel data  »
Abstract/Résumé «  This paper investigates spatial variations in product prices using an exhaustive micro dataset on fish transactions. The data record all transactions between vessels and wholesalers that occur on local fish markets in France during the year 2007. Spatial disparities in fish prices are sizable, even after fish quality, time, seller and buyer unobserved heterogeneity have been taken into account. The price difference between local fish markets can be explained to some extent by distance, but mostly by a coast effect (analogous to a border effect in the literature on the law of one price) related to separate location on the Atlantic and Mediterranean coasts. In particular, fish and crustacean prices are 34% higher on the Mediterranean coast. The law of one price is verified for almost all species when considering only local fish markets on the Atlantic coast.  »

Co-authored with Meglena Jelava - EconomiX CNRS, Université Paris Ouest La Défense
Abstract/Résumé «  The precautionary principle has emerged as a leading guide to the public decisions concerning environmental risks, when there is irreversibility and un-certainty. In this paper, we adopt a two-period model with irreversibility and agents differentiated by their degree of optimism, to characterize conditions of application of the precautionary principle. We show in particular that it is more often applied if the decision maker has an intermediate optimism index, if the scientific research is more efficient to reduce uncertainty, and if the same decision maker takes the decisions for both periods.  »

Titre / title of paper «  Where to Spend Foreign Aid to Counter Terrorism  »
Abstract/Résumé A simple game-theoretic model brings out conditions for terrorists to perform their attacks in a host country other than at home. This emphasizes the diluted impact of counterterrorism measures implemented in the host-country on the number of attacks taking place there. These measures might attract more imported attacks and mainly impact the number of attacks exported by the domestic terrorists without affecting much the overall level of terrorist activity in the host country. Cross-country and dyadic empirics support this prediction by contrasting the findings regarding the number of attacks per country of origin vs. per host country. They confirm that foreign aid in the source country is effective to counter terrorism, but they raise the issue of its effect on the venue of these terrorist attacks. Military interventions are mostly counter-productive, as they seem to attract terrorists.
