This paper examines the small world hypothesis. The first part of the paper presents empirical evidence on the evolution of a particular world: the world of journal publishing economists during the period 1970-2000. We find that in the 1970's the world of economics was a collection of islands,...

What insights can be gained from bringing the theory of the firm to the global economy? I discuss several new features of the world economy that can be explained by incorporating the theory of the firm into the theory of international trade. Among the new features I discuss are the move to...

We study how a preferential trade agreement (PTA) affects international sourcing decisions, aggregate productivity and welfare under incomplete contracting and endogenous matching. Contract incompleteness implies underinvestment. That inefficiency is mitigated by a PTA, because the agreement...

We study the holdup problem in repeated transactions between a seller and a buyer such that the seller makes relation-specific investments in each period. We show that where, under spot transaction, formal contracts have no value because of the cooperative nature of investment, writing a simple...

Can formal contracts help resolving the holdup problem? We address this important question by studying the holdup problem in repeated transactions between a seller and a buyer in which the seller can make relation-specific investments in each period. In contrast to previous findings, we...

When managers have objectives beyond maximizing monetary profits, inefficiencies may arise. An increase in competition may then force managers to improve the productivity of the firm in order to ensure survival. While this hypothesis has received ample theoretical attention, empirical evidence...

This paper develops a novel theory of capital mis-allocation within firms that stems from managers’ empire building and informational frictions within the organization. Introducing an internal capital market into a two-factor model of multi-segment firms, we show that international competition...

We study the welfare impact of rules of origin in free trade agreements where final-good producers source customized inputs from suppliers within the trading bloc. We employ a property-rights framework that features hold-up problems in suppliers' decisions to invest, and where underinvestment is...

Seminal theories of the firm posit that firm ownership is allocated to minimize contractual inefficiencies. Yet, it remains unclear how much the optimal ownership choice affects firm performance in practice. This paper provides a first quantification of the gains from optimal ownership within...

Over the last decades, the internationalization of the value chain has allowed firms to exploit cross-country differences in environmental and labor regulation (and enforcement) in ways that have led to a large number of NGO campaigns and consumer boycotts criticizing ‘unethical’ practices....
