This paper is a partial exploration of mechanisms through which global factors influence the tradeoffs that U.S. monetary policy faces. It considers three main channels. The first is the determination of domestic inflation in a context where international prices and global competition play a...

We develop a framework for studying trade in vertically and horizontally differentiated products. In our model, consumers with heterogeneous incomes and tastes purchase a homogeneous good as well as making a discrete choice of quality and variety of a differentiated product. The distribution of...

This paper develops a new framework for examining the distributional consequences of trade liberalization that is consistent with increasing inequality in every country, growth in residual wage inequality, rising unemployment, and reallocation within and between industries. While the opening of...

Most analyses of the macroeconomic adjustment required to correct global imbalances ignore net exports of new varieties of goods and services and do not account for firms' entry in the product market. In this paper we revisit the macroeconomics of trade adjustment in the context of the classic...

This paper explains three key stylized facts observed in industrialized countries: 1) portfolio holdings are biased towards local equity; 2) international portfolios are long in foreign currency assets and short in domestic currency; 3) the depreciation of a country's exchange rate is associated...

This paper develops a theory of financial crisis based on the demand side of the economy. We analyze the impact of financial and trade globalizations on asset prices, investment and the possibility of self-fulfilling financial crashes. In a two-country model, we show that financial and trade...

We define and study transparency, credibility, and reputation in a model where the central bank's characteristics are unobservable to the private sector and are inferred from the policy outcome. A low-credibility bank optimally conducts a more inflationary policy than a high-credibility bank, in...

We construct a model of growth based on endogenous technological change in a small, open economy. Entrepreneurs develop new intermediate products whenever the present value of potential profits exceeds the cost of R&D. Diversity of intermediates contributes to total factor productivity in the...

Globalization has been blamed for rising inequality in rich and poor countries. Yet the views of many protagonists in this debate are not based on evidence. To help form an evidence-based opinion, I review in this paper the theoretical and empirical literature on the relationship between...
