This paper analyses the effect of integration on growth when countries have different preferences. It describes a two-country two-sector model, with the first sector producing the homogeneous good and the second sector producing a differentiated good, which is divided in a first-class goods...

This paper integrates the analysis of choices on education and on technology adoption to study international economic disparities. Two candidate explanations are considered: di¤erences in distortions that a¤ect the cost of technology adoption and di¤erences in the e¤ectiveness of...

We study a simple model of public opinion formation that posits that interaction between neighbouring agents leads to bandwagons in the dynamics of individual opinions, as well as in that of the aggregate process. We show that in different specifications of the model, there is a tendency for the...

This paper contributes to the empirics of the intertemporal approach to the current account. We use a cointegrated VAR framework to identify permanent and transitory components of country-specific and global shocks. Our approach allows us to empirically investigate the sensitivity to persistence...

A key issue in monetary policy is that on the importance of following systematic behaviours. The paper revisits the classic debate on rules versus discretion focusing on the design of instrument rules in a manner that push discretionary policy choices in the direction of the commitment...

Intertemporal models of the current account generally assume that global shocks do not affect the current account. We use this assumption to identify global and country-specific shocks in a bivariate VAR. We test the quality of the identification using evidence from G7-data. In accordance with...

In intertemporal optimization models of current account dynamics, the budget constraint will induce high degrees of positive comovement in the levels of savings and investment and the two variables are likely to be cointegrated. Error correction will then also influence the correlations of the...

The possibility that a structural equation may not be identified casts doubt on the measures of estimator precision that are normally used. We argue that the observed identifiability test statistic is directly relevant to the precision with which the structural parameters can be estimated, and...

We study a continuous and balanced mechanism that is capable of implementing in Nash equilibrium all the Pareto-efficient individually rational allocations for an economy with public goods. The Government chooses a set of weights directly related to the Lindahl prices corresponding to the...

When marginal utility is convex and there is pure labour income uncertainty, certain results are well-known. Asset return uncertainty is often assumed to have qualitatively similar effects; see e.g. Skinner (1988). We show that this assumption is not correct. Asset return uncertainty gives rise...
