In this paper, we develop a network perspective on the welfare gains from trade in today’s internationally fragmented supply chains. Towards this end, we study a Ricardian trade model featuring trade in final and intermediate products, and introduce a novel comparative statics approach to...

The recent literature on firm-to-firm trade has documented salient empirical regularities of the buyer-seller network. We propose a simplistic re-interpretation of the classical Krugman (1980) model that accounts for surprisingly many of the empirical regularities. This re-interpretation relies...

In this paper, we propose a novel approach to the study of international trade that leads to a measure of country openness that is quite different from the various alternatives proposed by the received literature. In contrast to these, our measure does not use indicators of aggregate trade...

This paper studies structural change in production networks for intermediate inputs (input-output network) and new capital (investment network). For each network, we document a declining fraction of production by goods sectors and a rising fraction of production by services sectors. We develop a...

This paper develops a dynamic programming method when the one-stage deviation principle in the sense of mechanism design literature doesn’t hold. The commonly used dynamic programming method is valid only if the one-stage deviation principle in the sense of mechanism design literature is...

During the last decades, the United States has applied increasingly high trade protection against China. We combine detailed information on US antidumping (AD) duties — the most widely used trade barrier — with US input-output data to study the effects of trade protection along supply...

We examine the incentives and implications of supplier encroachment, when final good produc-tion requires the use of multiple complementary inputs and the entry of a supplier into the final good market gives rise to mutual outsourcing of inputs between the encroaching supplier and the incumbent....
