The recent fall of labor's share of GDP in numerous countries is well-documented, but its causes are poorly understood. We sketch a “superstar firm” model where industries are increasingly characterized by “winner take most” competition, leading a small number of highly profitable (and...

We investigate the link between hospital performance and managerial education by collecting a large database of management practices and skills in hospitals across nine countries. We find that hospitals that are closer to universities offering both medical education and business education have...

In many growth models, economic growth arises from people creating ideas, and the long-run growth rate is the product of two terms: the effective number of researchers and their research productivity. We present a wide range of evidence from various industries, products, and firms showing that...

The fall of labor's share of GDP in the United States and many other countries in recent decades is well documented but its causes remain uncertain. Existing empirical assessments of trends in labor's share typically have relied on industry or macro data, obscuring heterogeneity among firms. In...

We examine the impact of Chinese import competition on patenting, IT, R&D and TFP using a panel of up to half a million firms over 1996-2007 across twelve European countries. We correct for endogeneity using the removal of product-specific quotas following China's entry into the World Trade...

We simultaneously assess the contributions to productivity of three sources of research and development spillovers: geographic, technology and product-market proximity. To do this, we construct a new measure of geographic proximity that is based on the distribution of a firm's inventor locations...

We present a heterogeneous-firm model in which management ability increases both production efficiency and product quality. Combining six micro-datasets on management practices, production and trade in Chinese and American firms, we find broad support for the model's predictions. First, better...

We develop an incomplete-contracts model to jointly study firm boundaries and the al-location of decision rights within them. Integration has an option value: it gives firm owners authority to delegate or centralize decision rights, depending on who can best solve problems that may arise in the...

The British New Deal for Young People began in January 1998. After 6 months of unemployment, 18-24 year olds are mandated to enter a `Gateway' period where they are given extensive job search assistance. If they are unable to obtain an unsubsidised job, then they can enter one of four New Deal...

OECD labor markets have become more "polarized" with employment in the middle of the skill distribution falling relative to the top and (in recent years) also the bottom of the skill distribution. We test the hypothesis of Autor, Levy, and Murnane (2003) that this is partly due to information...
