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...

We use data from Argentina's household survey to evaluate the hypothesis that informal workers would expect higher wages in the formal sector. Using various definitions of informal employment we find that, on average, formal wages are higher than informal wages. Parametric tests suggest that a...

We construct a vintage capital model of economic growth in which the decision to replace old technologies with new ones is modeled explicitly. Depreciation in this environment is an economic, not a physical concept. We describe the balanced growth paths and the transitional dynamics of this...

We consider a small open economy where domestic residents combine their own income with credit obtained either at home or abroad in order to finance capital investments. These investments are subject to a costly state verification (CSV) problem. In addition, lenders to domestic residents...
