We present a model that explains how a cluster moves through a life cycle and why this movement differs from the industry life cycle. The model is based on three key processes: the changing heterogeneity in the cluster describes the movement of the cluster through the life cycle; the geographical absorptive capacity enables clustered companies to take advantage of a larger diversity of knowledg...

This paper investigates interactions between exporting and productivity at the firm level, using a panel of firms in the UK chemical industry. This is both highly technology intensive and the UK’s largest exporting sector. We find exporters are more productive than non-exporters, but are also on average smaller. This superior productivity performance among exporters appears to be caused by both...

Increased competition for viewers’ time is threatening the viability of publicservice broadcasters (PSBs) around the world. Changing regulations regarding advertising minutes might increase revenues, but little is known about the structure of advertising demand. To address this problem, we collect a unique dataset on monthly impacts (quantities) and prices of UK television channels between 2002...

We explore two main questions. First, can two markets for a company’s shares coexist and, if so, what determines the distribution of trading volume across them? For firms cross-listed in the U.S. we find that in most cases U.S. trading is a significant fraction of total volume, and tends to be larger for companies based in countries that are geographically close, with low financial development ...

Yearly sales of “fair trade” products exceeds $2.3 billion worldwide. Consumers who are altruistic and rational will choose these product-donation bundles when the bundle is cheaper than its elements. Assume a supplier’s investment reduces retailers’ costs (or improves quality), but this investment is non-verifiable, hence sub-optimal even with infinitely-repeated interaction. A retailer paying...

This paper analyzes the evolution of firm size distribution in the U.S. manufacturing industries over 35 years from 1963 to 1997. Firm size distribution undergoes systematic changes, the magnitude and the direction of which depend on whether an industry experiences a phase of growth, shakeout, stability, or decline. The observed patterns have implications for the theories of industry dynamics a...

The financial crisis renewed interest in the relation between pay-for-performance compensation and risk taking incentives. We examine whether paying top executives with options induces them to take more risk. To identify the causal effect of options, we exploit two distinct sources of variation in option compensation that arise from institutional features of multi-year grant cycles. We find tha...

We develop a simple theoretical model of a long term buyer-supplier relationship with non-contractible buyer specific R&D investment, and derive predictions on the effects of trust and competition on suppliers’ investment and buyers’ procurement strategies. We address these issues empirically using unique survey data on individual buyer-supplier relationships in the German automotive industry. ...
