Article
Canada exhibits no correlation between income and victimization, rich neighborhoods are less exposed to property crime, rich households are more victimized than their neighbors, and rich households and neighborhoods invest more in protection. We provide a theory consistent with these facts. Criminals within city choose a neighborhood and pay a sear...

In this article we propose a theoretical model to better comprehend the effect of gun laws on violence. We assume that a violent encounter between a criminal and a victim is costly to both, and we uncover two types of equilibria: a pure strategy violent equilibrium and a mixed strategy equilibrium where the criminal is deterred with strictly positi...
Article
This paper looks at situations in which public and private protection are complementary, that is, when private protection must be coordinated with public protection to be effective. For example, home alarms deter theft by being connected to a local police station: if the police do not respond to a home alarm, the home alarm on its own is virtually...
Article
Young Europeans experience high unemployment rates, job instability, and late emancipation. Meanwhile, they do not support reforms weakening protection on long‐term contracts. In this paper, we suggest a possible rationale for such reform distaste. When the rental market is strongly regulated, landlords screen applicants with regard to their abilit...

Human prosociality toward nonkin is ubiquitous and almost unique in the animal kingdom. It remains poorly understood, although a proliferation of theories has arisen to explain it. We present evidence from survey data and laboratory treatment of experimental subjects that is consistent with a set of theories based on group-level selection of cultur...
Article
This note evaluates the scrambled questions penalty using multiple choice tests taken by first-year undergraduate students who follow a microeconomics introductory course. We provide new evidence that students perform worse at scrambled questionnaires than at logically ordered ones. We improve on previous studies by explicitly modeling students ind...
Article
In this paper, a lobby group or union may influence public policy because it is able, via a costly signal such as a boycott or a strike, to negatively impact the image of decision makers. The competence of a government is measured by its ability to do a lot with only a little money. Voters receive, through observing the level of public output, only...
Article
A vast and often confusing economics literature relates competition to investment in innovation. Following Joseph Schumpeter, one view is that monopoly and large scale promote investment in research and development by allowing a firm to capture a larger fraction of its benefits and by providing a more stable platform for a firm to invest in R&D. Ot...
Article
Although there is mounting empirical evidence that the mere presence of borders contribute to reduce trade significantly, there is no firm view on what are the reasons underlying this phenomenon. This paper investigates the role played by asymmetries in judicial systems in driving the “border effect”. First, we provide evidence that differences in...
Article
Full-text available
We examine how the interaction between education and corruption affects institutional reform and economic development. While corruption reduces average income and education, education increases not only output and hence potential corruption rents, but also produces more informed electorates that better monitor government actions. We find that econo...
Article
Full-text available
This paper documents a strong positive relationship between individual reported trust levels (obtained from the US General Social Survey) and the competitiveness of the sector in which an individual works (obtained from the US census of firms). This correlation is robust to the inclusion of all of the previously studied determinants of individual t...
Article
Following the approach suggested by Favero and Rovelli (2002), I estimate a three-equations system for different sub-samples for Canada. The results indicate that the preferences of the monetary authority have changed between the different regimes. In particular, the parameter associated to the implicit target of inflation has been reduced signific...
Article
We re-examine the efficiency of observable and unobservable crime protection decisions with new results and insights. Observable protection is unambiguously associated with a negative externality. At the individual level, it reduces the crime effort, but its unit payoff remains unchanged. Conversely, unobservable protection reduces the unit payoff...
Article
Full-text available
In the present paper, we analyze an original channel of interaction between politicians and lobbies i.e. the nuisance power of a lobby. Some lobbies are influencing public policies just because they are able to impact negatively the image of a politician. More particularly, we develop a setting in which unions may transmit some information to the v...
Article
This paper introduces a new approach to successive oligopolies. We draw on market games a la ShapleyShubik to examine how successive oligopolies operate between downstream and upstream markets when the input price is determined by the action of all firms, downstream and upstream both. This approach differs from the classical one as it allows us to...
Article
Full-text available
We model the two way interaction between education, corruption and the level of output. Corruption reduces income levels and hence educational attainment. Education in turn affects the incentives for corruption: more education increases output and thus the rents from corruption, but it also increases the probability that the electorate identifies c...
Article
Given the background of changing institutional competencies in the European Union, we analyze the choice of asylum law standards of national and European parliaments, the Council of the European Union and codecision between the Council and the European Parliament. In a two country model we nd that the European arrangements maximize neither the welf...
Article
Full-text available
Recent evidence shows that the 'home bias puzzle' in international trade may be associated with the mere presence of national borders (McCallum (1995)). In this paper we provide a theoretical framework to explain why borders may matter so much for trade. Our argument is that even between perfectly integrated and similar countries the legal system d...
Article
Full-text available
In this paper, we analyze the trade war between two large countries when the trade policy is decided through majority voting. We show how the distributive aspect of trade policy interacts with the strategic aspect. It is shown that the voting equilibrium depends on the distribution of the factor endowment. If median voters in each country own relat...
Article
We present a fiscal competition model with two policy instruments: the level of corporate taxation and the tightness of control of profit shifting by multinational firms (MNF). We show that a country may optimally decide not to monitor the MNF for two reasons. Firstly, this country becomes an attractive location for MNF activity despite a high corp...
Article
Full-text available
Because the patent system is nowadays under criticisms, it is legitimate to question whether patents provide the best incentive mechanism for innovation. Wouldn’t it be preferable to base incentives on a reward system? This is the question addressed in this article, first in a general perspective and then, by considering the specific case of the ph...
Article
This paper addresses capital tax competition among an arbitrary number of countries. Countries are asymmetric not only in their population endowment but also in their capital endowment per inhabitant. National governments tax capital and labor in order to finance a fixed public budget. Asymmetric capital taxation arises at equilibrium leading to a...
Article
With international externalities, different country sizes, imperfect competition, and trade costs, tax competition for mobile firms is efficiency-enhancing with respect to the free market outcome. Under both scenarios, the resulting inefficiencies in international specialization and trade flows vanish when trade costs are low enough. Otherwise, onl...
Article
Full-text available
In this Paper, we develop a two country four region model allowing for a core periphery pattern inside countries. We then examine how both the integration and the agglomeration process inside a given country affects the pattern of specialization and international trade. We also analyse how agglomeration process interact from one country to the othe...
Article
This paper considers social protection, in the form of a minimum wage, in a global market. We show that trade, even without factor mobility, puts downward pressure on the level of the minimum wage determined by majority voting. This is due to the industrial specialization that results from the imposition of different minimum wages. We show that coo...
Article
This contribution investigates fiscal coordination in the framework of two countries asymmetric in respect of their capital-labor endowment. When tax policies are decided by majority voting inside each country, and they are not coordinated at a supranational level, factors of production are inefficiently allocated, at equilibrium. Our main result s...

This study analyzes the effects of right-wing extremism on the well-being of immigrants based on data from the German Socio-Economic Panel (SOEP) for the years 1984 to 2006 merged with state-level information on election outcomes. The results show that the life satisfaction of immigrants is significantly reduced if right-wing extremism in the nativ...
Article
Regions can benefit by offering infrastructure services that are differentiated by quality, thus segmenting the market for industrial location. Regions that compete on infrastructure quality have an incentive to increase the degree of differentiation between them. This places an upper bound on the number of regions successfully able to participate...

This paper addresses the issue of capital tax competition among an arbitrary number of countries. Countries are allowed to be asymmetric not only in their population endowment but also in their capital endowment per inhabitant. National governmentstax capital and labor in order to finance a public good. Asymmetric capital taxation arises at equilib...
Article
We identify cultural goods as goods which are valued differently by consumers at home than by individuals abroad, and which are produced under scale economies. It is shown that restrictions on the trade of cultural goods can raise welfare in both recipient and source countries.

This chapter examines empirical strategies that have been or could be used to evaluate the importance of agglomeration and trade models. This theoretical approach, widely known as “New Economic Geography” (NEG), emphasizes the interaction between transport costs and firm-level scale economies as a source of agglomeration. NEG focuses on forward and...
Article
Regions can benefit by offering infrastructure services that are differentiated. Competition between regions over potential investors is then less direct, allowing them to realize greater benefits from external investors. The two polar cases of full and incomplete information about investors' needs are studied. In both cases, there is regional diff...
Article
We show that immigrant managers are substantially more likely to hire immigrants than are native managers. The finding holds when comparing establishments in the same 5-digit industry and location, when comparing different establishments within the same firm, when analyzing establishments that change management over time, and when accounting for wi...
Article
This paper compares reward systems to intellectual property rights (patents and copyrights). Under a reward system, innovators are paid for innovations directly by the government (possibly on the basis of sales), and innovations pass immediately into the public domain. Thus, reward systems engender incentives to innovate without creating the monopo...

Basic economic theory identi…es a number of e¢ciency gains that derive from international capital mobility. But just as with free trade in goods, there is no guarantee that capital mobility makes everyone better o¤. Consequently, capital mobility may be politically unsustainable even though it enhances e¢ciency. This paper discusses how such a dile...
Article
In this paper, we use recent developments in economic theory as a basis to revisit the 'regional question' within the European Union, although the principles supporting our approach can be applied to other areas experiencing economic integration. Specifically, we would like to bring about the following two ideas: (i) major urban centres - metropoli...

In June 2009 a new financial supervisory framework for the European Union (EU) was endorsed, consisting of a macro- and a micro-prudential pillar. The latter is composed of a Steering Committee, a supranational layer and a network of national supervisory authorities at the bottom, de facto establishing a complex multiple principals-multiple agents...

Article
Full-text available
This paper analyses how the level of social protection is determined when its choice depends on political competition. First, this is done under autarky. Then the analysis is extended to take account of the existence of an international capital market. We show that social protection never increases under international competition and, in several ci...
Article
An example is provided identifying a case of inefficiency arising from the interplay of the voting mechanism and the market mechanism.
Article
This paper analyses the interaction between comparative advantages , social protection, and the political system. Considering entirely symmetrical countries whose production factors are immobile, we suggest that redistributive policies can be 'imported' or 'exported' depending on their impact on trade patterns. This points to the need for coordinat...
Article
In this paper, we analyze the trade war between two large countries when the trade policy is decided through majority voting. We show how the trade war equilibrium depends on the median voter production factor relative endowment. We compare this equilibrium to the one analyzed by Johnson where the trade policy is driven by an utilitarian benevolent...

This paper argues that housing market regulations (HMR) originate a social demand for employment protection legislation (EPL). Imperfections on the rental market and the mortgage market imply that getting a secure job gives a better access to housing. We …rst present micro and macro evidence suggesting that HMR and EPL are positively correlated. Th...
Article
Controlling for country fixed effects, there is a positive and statistically significant relationship between the degree of housing market regulation (HMR) and the strictness of employment protection legislation (EPL) in OECD countries. We provide a model in which HMR increases foreclosure costs in case of mortgage default, while EPL raises the adm...

This paper identifies the optimal two-period price sequence in the attempt for selling a good, with take-it-or-leave-it offers, when the seller faces ambiguity about the buyers' willingness to pay. If the first round fails, the seller updates its beliefs on the state of the market in accordance with Bayes rule and quotes a second and final price. W...

This paper first introduces an approach relying on market games to examine how successive oligopolies do operate between downstream and upstream markets. This approach is then compared with the traditional analysis of oligopolistic interaction in successive markets. The market outcomes resulting from the two approaches are analysed under different...
