Why not in your Backyard? On the Location and Size of a Public Facility

In this paper, we tackle the issue of locating a public facility which provides a public good in a closed and populated territory. This facility generates differentiated benefits to neighborhoods depending on their distance from it. In the case of a Nimby facility, the smaller is the distance, the lower is the individual benefit. The opposite is true in the case of an anti-Nimby facility. We first characterize the optimal location which would be chosen by a social planner. Then we introduce a common-agency lobbying game, where agents attempt to influence the location and provision decisions by the government. Some interesting results arise in the case where only a subset of neighborhoods lobby. First, the solution of the lobbying game can replicate the optimal solution. Second, under-provision and over-provision of the public good may be obtained both in the Nimby and the anti-Nimby cases. The provision outcome depends on the presence of either a congestion effect or an agglomeration effect. Third, some non-lobbying neighborhoods may be better off than in the case where all neighborhoods lobby, which raises the possibility of free-riding at the lobbying stage.

National Politics and International Agreements

International agreements about transnational issues are difficult to reach, as the examples of the Copenhagen summit or the never-ending discussions of the future of the European Union make clear. In this paper, we relate this difficulty to the political process and the conflicts of interest attached to an agreement, both within and between national electorates, related to national income distributions. We set up a political economy model of a two-country world economy, where an international agreement on the financing of an international public good has to be negociated by two elected national delegates. We prove that any international agreement involves higher taxes in both countries than in the case of no-agreement. If reachable, an IA may generate losers in either country. If the political process involves a constraint on tax rates, an agreement may or may not be reached. Finally, when an agreement is reached, it may exhibit strategic delegation when the median voters are the Condorcet winners in both countries : this delegation is the outcome of the struggle by electorates to transfer the tax burden to the other country's taxpayers. In brief, the fate of an international agreements depends on national politics and distributive issues in the involved countries.International agreements, bargaining, delegation, voting.

Deposit Insurance without Commitment: Wall St. versus Main St.

This paper studies the provision of deposit insurance without commitment in an economy with heterogenous households. When households are identical, deposit insurance will be provided ex post to reap insurance gains. But the ex post provision of deposit insurance redistributes consumption when households differ in their claims on the banking system as well as in their tax obligations to finance the deposit insurance. Deposit insurance will not be provided ex post if it requires a (socially) undesirable redistribution of consumption which outweighs insurance gains.

Does Inflation Targeting decrease Exchange Rate Pass-through in Emerging Countries ?

In this paper, we empirically examine the effect of inflation targeting on the exchange rate pass-through to prices in emerging countries. We use a panel VAR that allows us to use the larger data set on twenty-seven emerging countries (fifteen inflation targeters and twelve inflation nontargeters). Our evidence suggests that inflation targeting in emerging countries has helped to reduce the pass-through to various price indexes (import prices, producer prices and consumer prices) from a higher level to a new level that is significantly different from zero. The variance decomposition shows that the contribution of exchange rate shocks to prices fluctuations is more important in emerging targeters compared to nontargeters, and the contribution of exchange rate shocks to price fluctuations in emerging targeters declines after adopting inflation targeting.Inflation targeting, exchange rate pass-through, panel VAR.

Is inequality harmful for the environment in a growing economy ?

In this paper we investigate the relationship between inequality and the environment in a growing economy from a political economy perspective. We consider an endogenous growth economy, where growth generates pollution and a deterioration of the environment. Public expenditures may either be devoted to supporting growth or abating pollution. The decision over the public programs is done in a direct democracy, with simple majority rule. We prove that the median voter is decisive and show that inequality is harmful for the environment : the poorer the median voter relative to the average individual, the less she will tax and devote resources to the environment, preferring to support growth.Inequality, growth, environmental policy, political economy.

Designing Stabilization Policy in a Monetary Union

While the European Monetary Union (EMU) is now a reality, debate among economists nonetheless continues about the design and desirability of monetary unions. Since an the essential element of a monetary union is the delegation of monetary power to a single centralized entity, one of the key issues in this debate is whether a monetary union will limit the effectiveness of stabilization policy. If so, monetary union will not necessarily be welfare improving. In this paper, we study a two-country world economy and consider various designs of monetary union. We argue that the success of monetary union depends on: (i) the commitment ability of the single central bank, (ii) the policy flexibility of the national fiscal authorities and the central monetary authority and (iii) the cross country correlation of shocks. If, for example, the central bank moves before the fiscal authorities, then a monetary union will increase welfare as long as fiscal policy is sufficiently responsive to shocks. However, if the fiscal authorities have a restricted set of tools and/or the monetary authority lacks the ability to commit to its policy, then monetary union may not be desirable.

On policy interactions among nations: when do cooperation and commitment matter?

This paper offers a framework to study commitment and cooperation issues in games with multiple policymakers. To reconcile some puzzles in the recent literature on the nature of policy interactions among nations, we prove that games characterized by different commitment and cooperation schemes can admit the same equilibrium outcome if certain spillover effects vanish at the common solution of these games. We provide a detailed discussion of these spillovers, showing that, in general, commitment and cooperation are nontrivial issues. Yet in linear-quadratic models with multiple policymakers, commitment and cooperation schemes are shown to become irrelevant under certain assumptions. The framework is sufficiently general to cover a broad range of results from the recent literature on policy interactions as special cases, both within monetary unions and among fully sovereign nations.International economic relations ; Game theory

Leadership in Public Good Provision: a Timing Game Perspective

We address in this paper the issue of leadership when two governments provide public goods to their constituencies with cross border externalities as both public goods are valued by consumers in both countries. We study a timing game between two different countries: before providing public goods, the two policymakers non-cooperatively decide their preferred sequence of moves. We establish conditions under which a first- or second-mover advantage emerges for each country, highlighting the role of spillovers and the strategic complementarity or substitutability of public goods. As a result we are able to prove that there is no leader when, for both countries, public goods are substitutable. When public goods are complements for both countries, both countries may emerge as the leader in the game. Hence a coordination issue arises. We use the notion of risk-dominance to select the leading government. Lastly, in the mixed case, the government for whom public goods are substitutable becomes the leader.public good;Spillovers;Subgame Perfect Equilibrium;Strategic Complements;Stackelberg;Pareto Dominance;Risk Dominance
