This paper studies the macroeconomic effects of an inflow of low-skilled workers into an economy where there is capital accumulation, endogenous labour supply and heterogeneous workers. We find substantial dynamic effects, with adjustments that resemble those triggered by a sudden disruption of...

A number of authors have attempted to test whether the US economy is in a determinate or an indeterminate equilibrium. We argue that to answer this question, one must impose a priori restrictions on lag length that cannot be tested. We provide examples of two economic models. Model 1 displays an...

We study identification in a class of linear rational expectations models. For any given exactly identified model, we provide an algorithm that generates a class of equivalent models that have the same reduced form. We use our algorithm to show that a model proposed by Benhabib and Farmer [1] is...

This paper considers a general class of nonlinear rational-expectations models in which policymakers seek to maximize an objective function that may be household expected utility. We show how to derive a target criterion that is: (i) consistent with the model's structural equations, (ii) strong...

Expectations play a central role in modern macroeconomics. The econometric learning approach, in line with the cognitive consistency principle, models agents as forming expectations by estimating and updating subjective forecasting models in real time. This approach provides a stability test for...

The present paper contributes to the literature on dynamic games with strategic complementarities, in two interrelated ways. First, we identify a class of dynamic complete information games in which intertemporal complementarities and multiple equilibria can be fruitfully analyzed. Second, we...
