Business support policies designed to raise productivity and employment are common worldwide, but rigorous micro-econometric evaluation of their causal effects is rare. We exploit multiple changes in the area-specific eligibility criteria for a major program to support manufacturing jobs...

Nishimura et al. (2005) analyze the entry/exit behavior of Japanese firms during the 1990s and find that relatively efficient firms exited while relatively inefficient firms survived during the banking-crisis period of 1996-97. They conclude that the natural selection mechanism (NSM) apparently...

Set-asides and subsidies are used extensively in government procurement and natural resource sales. We analyze these policies in an empirical model of U.S. Forest Service timber auctions. The model fits the data well both within the sample of unrestricted sales where we estimate the model, and...

Recent research has suggested that the reduction of entry regulation can promote firm entry and job creation, but little is known about the quality of firms and jobs created through these reforms. To shed light on this question, we employ data from Portugal, a country which implemented one of...

This paper reviews recent academic work on the spatial concentration of entrepreneurship and innovation in the United States. We discuss rationales for the agglomeration of these activities and the economic consequences of clusters. We identify and discuss policies that are being pursued in the...

We use a new database, the National Establishment Time Series (NETS), to revisit the debate about the role of small businesses in job creation. Birch (e.g., 1987) argued that small firms are the most important source of job creation in the U.S. economy, but Davis et al. (1996a) argued that this...

The paper examines whether there is a significant relationship between economic growth and the degree of urban concentration, as measured by primacy, or the share of the largest metro area in national urban population. Is there reason to believe many countries have excessive primacy and how...

How much economic value did the diffusion of broadband create? We provide benchmark estimates for 1999 to 2006. We observe $39 billion of total revenue in Internet access in 2006, with broadband accounting for $28 billion of this total. Depending on the estimate, households generated $20 to $22...

This paper presents a new data set on the diffusion of about 115 technologies in over 150 countries over the last 200 years. We use this comprehensive data set to uncover general patterns of technology diffusion. Our main 5 findings are as follows: (i) Once the intensive margin is measured,...

Average income per capita in the countries of the OECD was more than 20 times larger in 2000 than that of the poorest countries of sub-Sahara Africa and elsewhere, and many of the latter are not only falling behind the world leaders, but have even regressed in recent years. At the same time,...
