This paper studies the macroeconomic effect and underlying firm-level transmission channels of a reduction in business entry costs. We provide novel evidence on the response of firms' entry, exit, and employment decisions. To do so, we use as a natural experiment a reform in Portugal that reduced entry time and costs. Using the staggered implementation of the policy across the Portuguese municipalities, we find that the reform increased local entry and employment by, respectively, 25% and 4.8% per year in its first four years of implementation. Moreover, around 60% of the increase in employment came from incumbent firms expanding their size, with most of the rise occurring among the most productive firms. Standard models of firm dynamics, which assume a constant elasticity of substitution, are inconsistent with the expansionary and heterogeneous response across incumbent firms. We show that in a model with heterogeneous firms and variable markups the most productive firms face a lower demand elasticity and expand their employment in response to increased entry.

Among the most revolutionary and productive areas of economic research over the last two decades, modern business cycle theory is finally made accessible to students and professionals in this rigorous, unified, introductory volume. This theory starts with the view that growth and fluctuations are not distinct phenomena to be studied separately--and that business cycles result from shocks (such as the availability of new technologies), which regularly affect most economies. The unifying theme of this book is the use of the neoclassical growth framework to study the economic fluctuations associated with the business cycle. Presenting recent advances in dynamic economic theory and computational methods--with emphasis on the construction of equilibrium paths for simple artificial economies--leading experts orient readers in the quantitative study of aggregate fluctuations and apply its concepts to key issues in macroeconomics and business cycle theory. This volume covers such issues as the aggregate labor market, the role of the household sector, the role of money, the behavior of asset markets, non-Walrasian economies, monopolistically competitive economies, international business cycles, and the design of economic policies. The contributors are David Backus, V. V. Chari, Lawrence Christiano, Thomas F. Cooley, Jean-Pierre Danthine, John Donaldson, Jeremy Greenwood, Gary D. Hansen, Patrick Kehoe, Finn Kydland, Edward C. Prescott, Richard Rogerson, Julio Rotemberg, Geert Rouwenhorst, José-Víctor Ríos-Rull, Michael Woodford, and Randall Wright.

New goods are at the heart of economic progress. The eleven essays in this volume include historical treatments of new goods and their diffusion; practical exercises in measurement addressed to recent and ongoing innovations; and real-world methods of devising quantitative adjustments for quality change. The lead article in Part I contains a striking analysis of the history of light over two millenia. Other essays in Part I develop new price indexes for automobiles back to 1906; trace the role of the air conditioner in the development of the American south; and treat the germ theory of disease as an economic innovation. In Part II essays measure the economic impact of more recent innovations, including anti-ulcer drugs, new breakfast cereals, and computers. Part III explores methods and defects in the treatment of quality change in the official price data of the United States, Canada, and Japan. This pathbreaking volume will interest anyone who studies economic growth, productivity, and the American standard of living.
