A positive and normative evaluation of alternative monetary policy regimes is addressed in a two-country general equilibrium model. The behaviour of the exchange rate, as well as of the other macroeconomic variables, depends crucially on the monetary regime chosen, though not necessarily on...

This Paper presents a two-country dynamic general equilibrium model with imperfect competition and nominal price rigidities in which terms of trade shocks coexist with inefficient supply shocks. We analyse the features of the optimal cooperative solution. While terms of trade shocks should be...

A two-country dynamic general-equilibrium model with imperfect competition and price stickiness is considered. This work shows the conditions under which price stability can implement the flexible-price allocation as a Nash equilibrium. This is possible if and only if both countries maintain a...

This paper provides first and second-order approximation methods for the solution of non-linear dynamic stochastic models in which the exogenous state variables follow conditionally-linear stochastic processes displaying time-varying risk. The first-order approximation is consistent with a...

We present evidence on the effect of social connections between workers and managerson productivity in the workplace. To evaluate whether the existence of social connections isbeneficial to the firm’s overall performance, we explore how the effects of social connectionsvary with the strength...

This paper presents evidence on how farmers’ decisions to adopt a new crop, sunflower,relate to the adoption choices of farmers in their social network of family and friends. Weshow that the relationship is shaped as an inverse-U, suggesting social effects are positivewhen there are few...

We present evidence on whether workers have social preferences by comparing workers’ productivityunder relative incentives, where individual effort imposes a negative externality on others,to their productivity under piece rates, where it does not. We find that the productivity of theaverage...

The ability to cooperate in collective action problems — such as those relating to the useof common property resources or the provision of local public goods — is a key determinant ofeconomic performance. In this paper we discuss two aspects of collective action problemsin developing...
