International supply chains require the coordination of numerous activities across multiple countries and firms. This paper develops a theoretical model of supply chains in which the measure of tasks completed within a firm is determined by parameters that define transaction costs and the cost...

Almost all of the literature about the growth of income inequality and the relationship between skilled and unskilled wages approaches the issue from the production side of general equilibrium (skill-biased technical change, international trade). Here, we add a role for income-dependent demand...

This paper examines demand systems where the demand for a good depends only on its own price, consumer income, and a single aggregator synthesizing information on all other prices. This generalizes directly-separable preferences where the Lagrange multiplier provides such an aggregator. As...

Primary commodities are used as inputs into all production processes, yet they account for approximately 16 percent of world trade. Despite their share in trade, we show that the aggregate gains from trade are largely understated if we ignore key features of commodities: low price elasticities...

This paper investigates the role of income-driven differences in consumption patterns in explaining and projecting energy demand and CO₂ emissions. We develop and estimate a general-equilibrium model with non-homothetic preferences across a large set of countries and sectors, and trace embodied...

A growing literature has documented the role of rm heterogeneity within sectors in accounting for nominal income inequality. This paper explores the implications for household price indices across the income distribution. Using detailed matched US home and store scanner microdata, we present...

International trade theory is a general-equilibrium discipline, yet most of the standard portfolio of research focuses on the production side of general equilibrium. In addition, we do not have a good understanding of the relationship between characteristics of goods in production and...

Advanced market economies are characterized by a continuous process of creative destruction. Market forces and technological developments play a major role in shaping this process, but institutional and policy settings also influence firms' decision to enter, to expand if successful and to exit...

We propose two distinct approaches to the measurement of industry upstreamness (or average distance from final use) and show that they yield an equivalent measure. Furthermore, we provide two additional interpretations of this measure, one of them related to the concept of forward linkages in...
