Tech clusters like Silicon Valley play a central role for modern innovation, business competitiveness, and economic performance. This paper reviews what constitutes a tech cluster, how they function internally, and the degree to which policy makers can purposefully foster them. We describe the...

The explosion of multinational activities in recent decades is rapidly transforming the global landscape of industrial production. But are the emerging clusters of multinational production the rule or the exception? What drives the offshore agglomeration of multinational firms in comparison to...

This paper explores the role of knowledge flows and productivity growth by linking direct survey data on knowledge flows to firm-level data on TFP growth. Our data measure the information flows often considered important, especially by policy-makers, such as from within the firm and from...

We document the evolution of the newly created market for frequency response within the UK electricity system over a six-year period. Firms competed in price while facing considerable initial uncertainty about market demand and rival behavior. We show that over time prices stabilized, converging...

This paper provides a general and unified framework to study the role of production networks in international GDP comovement. We first derive an additive decomposition of bilateral GDP comovement into components capturing shock transmission and shock correlation. We quantify this decomposition...

The international production and distribution networks consist of vertical production chains and distribution networks extended across a number of countries. This paper claims that the international production and distribution networks in East Asia present distinctive characters in their...

In recent decades, growth of overall world trade has been driven in large part by the rapid growth of trade in intermediate inputs. Much of this input trade involves multinational firms locating input processing in their foreign affiliates, thereby creating global vertical production networks....

The location of US multinational foreign R&D has shifted significantly to include emerging markets in addition to traditional Western R&D hubs, resulting in two challenges for multinationals: (1) how to transfer knowledge across geographic distances, and (2) how to facilitate learning when local...

This paper develops a dynamic model of cross-border M&A activity. We show that foreign firms will be relatively more attracted to targets in the domestic country that had high productivity levels several years prior to acquisition, but then suffered a negative productivity shock (i.e., cherries...

This paper empirically examines the effects of financial crises on the organization of production of multinational enterprises. We construct a panel of European multinational networks from 2003 through 2015. We use as a financial shock the increase in risk premia between August 2007 and July...
