This paper explores the impact of changes in the composition of government spending on the level of relative prices, interest rates and the current account in a two country, two period Heckacher-Ohlii model. We show that shifting the composition of government spending affects macroeconomic...

I explore whether the world trading system of the twentieth century can be adapted to address the challenges of the twenty-first. I first develop an understanding of how GATT functioned during the twentieth century, and which features of the economic environment were most important in...

The design of a trade agreement should reflect its purpose. Does digital trade change the purpose of a trade agreement? To explore this question, I first describe the definitional and classification issues associated with digital trade, and for modeling purposes I adopt a simple taxonomy of the...

What are the potential benefits from establishing international rules for the conduct of trade policy and how should these rules be designed? These questions are of central importance to the evolution of national trade policies in the post-war era, a period in which an elaborate system of...

This paper proposes a theory of gradual trade liberalization. I consider countries that are limited to self-enforcing arrangements in their trade relations. I argue that enforcement problems associated with the maintenance of low cooperative tariffs are exacerbated by the presence of resources...

This paper derives statements of the Heckscher-Ohlin Theorem which remain valid in the presence of market power. Following Helpman (1 984a), the paper explores restrictions on permissible trade patterns that are implied by the post-trade equilibrium conditions of Heckscher- Ohlin theory....

This paper examines the interaction between union wages and the international pattern of production and trade. If union goods are heterogeneous in labor intensity, the introduction of an active union in the domestic country causes only the least labor-intensive range of union goods to be...

This paper provides a unified framework for interpreting a wide range of interactions models which have appeared in the economics literature. A formalization taken from the statistical mechanics literature is shown to encompass a number of socioeconomic phenomena ranging from out of wedlock...

This paper explores the dynamics of income inequality by studying the evolution of human capital investment and neighborhood choice for a population of families. Parents affect the conditional probability distribution of their children's income through the choice of a neighborhood in which to...

This paper proposes a method of testing whether a time series is a martingale. The procedure develops an asymptotic theory for the shape of the spectral distribution function of the first differences. Under the null hypothesis, this shape should be a diagonal line. several tests are developed...
