Existing estimates of power laws in firm size typically ignore the impact of international trade. Using a simple theoretical framework, we show that international trade systematically affects the distribution of firm size: the power law exponent among exporting firms should be strictly lower in absolute value than the power law exponent among non-exporting rms. We use a dataset of French firms to demonstrate that this prediction is strongly supported by the data. While estimates of power law exponents have been used to pin down parameters in theoretical and quantitative models, our analysis implies that the existing estimates are systematically lower than the true values. We propose two simple ways of estimating power law parameters that take explicit account of exporting behavior.

Economic and social progress requires a diverse ecosystem of firms that play complementary roles. Making It Big: Why Developing Countries Need More Large Firms constitutes one of the most up-to-date assessments of how large firms are created in low- and middle-income countries and their role in development. It argues that large firms advance a range of development objectives in ways that other firms do not: large firms are more likely to innovate, export, and offer training and are more likely to adopt international standards of quality, among other contributions. Their particularities are closely associated with productivity advantages and translate into improved outcomes not only for their owners but also for their workers and for smaller enterprises in their value chains. The challenge for economic development, however, is that production does not reach economic scale in low- and middle-income countries. Why are large firms scarcer in developing countries? Drawing on a rare set of data from public and private sources, as well as proprietary data from the International Finance Corporation and case studies, this book shows that large firms are often born large—or with the attributes of largeness. In other words, what is distinct about them is often in place from day one of their operations. To fill the “missing top†? of the firm-size distribution with additional large firms, governments should support the creation of such firms by opening markets to greater competition. In low-income countries, this objective can be achieved through simple policy reorientation, such as breaking oligopolies, removing unnecessary restrictions to international trade and investment, and establishing strong rules to prevent the abuse of market power. Governments should also strive to ensure that private actors have the skills, technology, intelligence, infrastructure, and finance they need to create large ventures. Additionally, they should actively work to spread the benefits from production at scale across the largest possible number of market participants. This book seeks to bring frontier thinking and evidence on the role and origins of large firms to a wide range of readers, including academics, development practitioners and policy makers.

John Sutton sets out a unified theory that encompasses two major approaches to studying market, while generating a series of novel predictions as to how markets evolve. Traditionally, the field of industrial organization has relied on two unrelated theories—the cross-section theory and the growth-of-firms theory—to explain cross-industry differences in concentration and within-industry skewness. The two approaches are based on very different mathematical structures and few researchers have attempted to relate them to each other. In this book, John Sutton unifies the two approaches through a theory that rests on three simple principles. The first two, a "survivor principle" that says that firms will not pursue loss-making strategies, and an "arbitrage principle" that says that if a profitable opportunity is available, some firm will take it, suffice to define a set of possible outcomes. The third, the "symmetry principle," says that the strategy used by a new entrant into any submarket depends neither on the entrants identity nor on its history in other submarkets. This allows researchers to bring together the roles of strategic interactions and of independence effects. The result is that the considerations motivating the cross-section tradition and those motivating the growth-of-firms tradition both drop out within a single game-theoretic model. This book follows Sutton's Sunk Costs and Market Structure, published by MIT Press in 1991.

Combining a statistical physics approach and rigorous econometric analysis, this new framework looks at growth and decline in business firms.

Often considered one of the major forces behind economic growth and development, the entrepreneurial firm can accelerate the speed of innovation and dissemination of new technologies, thus increasing a country's competitive edge in the global market. As a result, cultivating a strong culture of entrepreneurial thinking has become a primary goal throughout the world. Surprisingly, there has been little systematic research or comparative analysis to show how the growth of entrepreneurship differs among countries in various stages of development. International Differences in Entrepreneurship fills this void by explaining how a country's institutional differences, cultural considerations, and personal characteristics can affect the role that entrepreneurs play in its economy. Developing an understanding of the origins of entrepreneurs as well as the choices they make and the complexity of their activities across countries and industries are of central importance to this volume. In addition, contributors consider how environmental factors of individual economies, such as market regulation, government subsidies for banks, and support for entrepreneurial culture affect the industry and the impact that entrepreneurs have on growth in developing nations.

Utilizing a unique data set, Zoltan Acs and David Audretsch provide a rich empirical analysis of the increased importance of small firms in generating technological innovations and their growing contribution to the U.S. economy. They identify the contributions made by both small and large firms to the innovative process and the manner in which market structure, and the firm-size distribution in particular, responds to technological change. The authors' analysis relies on traditional theories of industrial organization and tests existing hypotheses, many of them previously untested due to data constraints. Innovation and Small Firms brings together two large data bases recently released by the U. S. Small Business Administration - one directly measuring innovative activity for large and small firms, the other providing a detailed census of economic activity for all manufacturing firms and plants across a broad spectrum of industries. Acs and Audretsch describe and evaluate the data bases in the context of the literature on innovation, market structure, and firm size. They present their findings on the presence of small firms, small-firm entry in manufacturing, small-firm growth and flexible technology, and mobility and firm size. They compare static and dynamic measures of small-firm viability and address the relationships between R&D, innovation, and productivity, and analyze the interaction between technological regimes and the role of government in innovation.
