This paper examines the extent to which the process of globalization can explain the observed widening in the cross--country distribution of output--per--worker. In particular examine whether the opening up of trade in a Hecksher--Ohlin type model of trade can explain the observed changes. On...

This paper is motivated by a set of cross-country observations on labor productivity growth among industrial countries over the period 1960-1997. In particular, we show that over this period, the speed of convergence among industrialized countries has decreased substantially while the negative...

This papers examines changes in the distribution of per-worker-output across countries over the period 1960-98, with a particular focus on identifying the forces behind the hollowing out of the middle of the distribution and the associated emergence of a twin-peaks phenomenon. The main finding...

Gold rushes are periods of economic boom, generally associated with large increases in expenditures aimed at securing claims near new found veins of gold. An interesting aspect of gold rushes is that, from a social point of view, much of the increased activity is wasteful since it contributes...

We enrich workhorse macroeconomic models with a mechanism that proxies strategic uncertainty and that manifests itself as waves of optimism and pessimism about the short-term economic outlook. We interpret this mechanism as variation in confidence and show that it helps account for many salient...

We study the Ramsey policy problem in an economy in which firms face a collateral constraint. Issuing more public debt alleviates this friction by increasing the aggregate quantity of collateral. In so doing, however, the issuance of more debt also raises interest rates, which in turn increases...

We show that international trade in goods is the main determinant of international equity portfolios and offers a compelling -- theoretically and empirically -- resolution of the portfolio home bias puzzle. The model implies that investors can achieve full international risk diversification if...

There is a widespread belief that changes in expectations may be an important independent driver of economic fluctuations. The news view of business cycles offers a formalization of this perspective. In this paper we discuss mechanisms by which changes in agents' information, due to the arrival...

Over the 1980s and 1990s the wage differentials between men and women (with similar observable characteristics) declined significantly. At the same time, the returns to education increased. It has been suggested that these two trends may reflect a common change in the relative price of a skill...

Recessions often happen after periods of rapid accumulation of houses, consumer durables and business capital. This observation has led some economists, most notably Friedrich Hayek, to conclude that recessions mainly reflect periods of needed liquidation resulting from past over-investment....
