This paper concerns Floer homology for periodic orbits and for a Lagrangian intersection problem on the cotangent bundle T ∗ M of a compact orientable manifold M. The first result is a new L ∞ estimate for the solutions of the Floer equation, which allows to deal with a larger and more natural class of Hamiltonians. The second and main result is a new construction of the isomorphism between the Floer homology and the singular homology of the free loop space of M, in the periodic case, or of the based loop space of M, in the Lagrangian intersection problem. The idea for the construction of such an isomorphism is to consider a Hamiltonian which is the Legendre transform of a Lagrangian on TM, and to construct an isomorphism between the Floer complex and the Morse complex of the classical Lagrangian action functional on the space of W 1,2 free or based loops on M.

This paper reviews methods for the estimation of dynamic discrete choice structural models and discusses related econometric issues. We consider single agent models, competitive equilibrium models and dynamic games. The methods are illustrated with descriptions of empirical studies which have applied these techniques to problems in different areas of economics. Programming codes for the estimation methods are available in a companion web page.

This paper studies the estimation of dynamic discrete games of incomplete information. Two main econometric issues appear in the estimation of these models: the indeterminacy problem associated with the existence of multiple equilibria and the computational burden in the solution of the game. We propose a class of pseudo maximum likelihood (PML) estimators that deals with these problems, and we study the asymptotic and finite sample properties of several estimators in this class. We first focus on twostep PML estimators, which, although they are attractive for their computational simplicity, have some important limitations: they are seriously biased in small samples; they require consistent nonparametric estimators of players ’ choice probabilities in the first step, which are not always available; and they are asymptotically inefficient. Second, we show that a recursive extension of the twostep PML, which we call nested pseudo likelihood (NPL), addresses those drawbacks at a relatively small additional computational cost. The NPL estimator is particularly useful in applications where consistent nonparametric estimates of choice probabilities either are not available or are very imprecise, e.g., models with permanent unobserved heterogeneity. Finally, we illustrate these methods in Monte Carlo experiments and in an empirical application to a model of firm entry and exit in oligopoly markets using Chilean data from several retail industries.

Differences in income elasticities and trends in real exchange rates
, 1989
"... One might expect that differences in income elasticities in trade and/or differences in growth rates among countries would give rise to strong secular trends in real exchange rates; for example, fastgrowing countries might need steady depreciation to get the world to accept their growing exports.

One might expect that differences in income elasticities in trade and/or differences in growth rates among countries would give rise to strong secular trends in real exchange rates; for example, fastgrowing countries might need steady depreciation to get the world to accept their growing exports. In fact, however, income elasticities are systematically related to growth rates by the "45degree rule", under which fastgrowing countries appear to face high income elasticities of demand for their exports, while having low income elasticities of import demand. The net effect of this relationship between elasticities and growth rates is that secular trends in real exchsngerstes are much smaller than one might otherwise have expected: relative PPP holds fairly well. This paper documents the existence of a "45degree rule", and suggests an explanation in terms of increasing returns and product differentiation.

We use the HyperKähler quotient of flat space to obtain some monopole moduli space metrics in explicit form. Using this new description, we discuss their topology, completeness and isometries. We construct the moduli space metrics in the limit when some monopoles become massless, which corresponds to nonmaximal symmetry breaking of the gauge group. We also introduce a new family of HyperKähler metrics which, depending on the “mass parameter ” being positive or negative, give rise to either the asymptotic metric on the moduli space of many SU(2) monopoles, or to previously unknown metrics. These new metrics are complete if one carries out the quotient of a nonzero level set of the moment map, but develop singularities when the zeroset is considered. These latter metrics are of relevance to the moduli spaces of vacua of three dimensional gauge theories for higher rank gauge groups. Finally, we make a few comments concerning the existence of closed or bound orbits on some of these manifolds and the integrability of the geodesic flow. 1

Using data on elections to the United States House of Representatives (19461998), this paper exploits a quasiexperiment generated by the electoral system in order to determine if political incumbency provides an electoral advantage – an implicit firstorder prediction of most principalagent theories of politician and voter behavior. Candidates who just barely won an election (barely became the incumbent) are likely to be ex ante comparable in all other ways to candidates who barely lost, and so their differential electoral outcomes in the next election should represent a true incumbency advantage. The regression discontinuity analysis provides striking evidence that incumbency has a significant causal effect of raising the probability of subsequent electoral success –by about 0.40 to 0.45. Simulations – using estimates from a structural model of individual voting behavior – imply that about twothirds of the apparent electoral success of incumbents can be attributed to voters ’ valuation of politicians ’ experience. The quasiexperimental analysis also suggest that heuristic “fixed effects ” and “instrumental variable” modeling approaches would have led to misleading inferences in this context.
