Employment to population ratios differ markedly across OECD countries relative to rates in the U.S., especially for persons aged 55-69. Social security features also differ across the OECD, particularly with respect to replacement rates, entitlement ages and earnings tests. I conjecture that...

We study a class of direct revelation mechanisms which implement outcome functions satisfying a monotonicity condition. Monotone implementation is in dominant strategy equilibrium when values are private and in ex post Nash equilibrium when values are interdependent. The original...

We study a two-player dynamic investment model with information externalities and provide necessary and sufficient conditions for a unique switching equilibrium. When the public information is sufficiently high and a social planer therefore expects an investment boom, investments should be...

This article introduces a unified methodology for estimating and testing nonlinear econometric models defined by conditional moment restrictions. These models are very common in econometrics, such as nonlinear rational expectation models. The current approach for inference in these models is the...

Using retail price survey data, I investigate whether international goods' market segmentation implied by dispersion in goods' prices is consistent with market segmentation implied by observed trade flows. A Ricardian trade model, with heterogeneous and asymmetric bilateral trade costs, accounts...

We analyze a stochastic growth model with lags in the operation of new technologies. Stock values are impacted by news on technological innovations and some other external shocks affecting the economy. Episodes of technology adoption may generate long fluctuations in the aggregate value of...

The Axiom of Monotonicity (AM) is a necessary condition for a number of expected utility representations, including those obtained by de Finetti (1930), von Neumann and Morgenstern (1944) and Savage (1954). The paper reports on experiments that directly test AM by eliminating strategic...

In this paper I consider choice correspondences defined on an extended domain: the decisions are assumed to be taken not by individuals, but by committees and, in addition to the budget sets, committee composition is observable and variable. For the case of varying committees choosing over a...

Motivated by the fact that, over the business cycle, labor dynamics in emerging economies differ in nontrivial ways from those observed in developed economies, we assess the relative importance of trend shocks in emerging economies in the business cycle model of Aguiar and Gopinath (2007) when...

We consider the nature of the relationship between the real exchange rate and capital formation. We present a model of a small open economy that produces and consumes two goods, one tradable and one not. Domestic residents can borrow and lend aborad, and costly state verification (CSV) is a...
