Book Description
This paper quantifies the origins of firm size heterogeneity when firms are interconnected in a production network. Using the universe of buyer-supplier relationships in Belgium, the paper develops a set of stylized facts that motivate a model in which firms buy inputs from upstream suppliers and sell to downstream buyers and final demand. Larger firm size can come from high production capability, more or better buyers and suppliers, and/or better matches between buyers and suppliers. Downstream factors explain the vast majority of firm size heterogeneity. Firms with higher production capability have greater market shares among their customers, but also higher input costs and fewer customers. As a result, high production capability firms have lower sales unconditionally and higher sales conditional on their input prices. Counterfactual analysis suggests that the production network accounts for more than half of firm size dispersion. Taken together, our results suggest that multiple firm attributes underpin their success or failure, and that models with only one source of firm heterogeneity fail to capture the majority of firm size dispersion.

Book Description
We estimate a structural model of heterogeneous multiproduct firms to examine the sources of firm heterogeneity emphasized in the recent trade and macro literatures. Using Nielsen barcode data on prices and sales, we estimate elasticities of substitution within and between firms, and use the estimated model to recover unobserved qualities, marginal costs and markups. We find that variation in firm quality and product scope explains at least four fifths of the variation in firm sales. Most firms are well approximated by the monopolistic competition benchmark of constant markups, but the largest firms that account for most of aggregate sales depart substantially from this benchmark. Although the output of multiproduct firms is differentiated, cannibalization is quantitatively important for the largest firms. This imperfect substitutability of products within firms, and the fact that larger firms supply more products than smaller firms, implies that standard productivity measures are not independent of demand system assumptions and probably dramatically understate the relative productivity of the largest firms.

Book Description
An extensive literature documents large and persistent within-industry heterogeneity of firm performance. While some authors explain such evidence in terms of factor misallocation, we provide an alternative framework that is based on the interaction among exogenous and endogenous factors. Exogenous factors, both supply and demand-related, define the opportunity set that is available to firms. Endogenous factors reflect instead firm-specific interpretations of such set, which combined with the available resources and capabilities determine firm's strategic responses that can be markedly heterogeneous. Whenever the diversity of firm conducts is associated with relatively small profit differentials, firm heterogeneity can persist. Evidence based on the evolution of labour productivity and profit dispersion in the Italian manufacturing sector between the 1990s and early 2000s provides support for our interpretative framework.

Book Description
We analyse the impact of relaxing rules of origin (ROOs) in a simple setting with heterogeneous firms that buy intermediate inputs from domestic and foreign sources. In particular, we consider the impact of switching from bilateral to diagonal cumulation when using preferences (instead of paying the MFN tariff) involving the respect of rules of origin. We find that relaxing the restrictiveness of the ROOs leads the least productive exporters to stop exporting. The empirical part confirms these results. We use the most recent techniques developed by Helpman, Melitz and Rubinstein (2007) on highly disaggregated data (HS6 digit) to analyse the effects of the introduction of the Pan-European Cumulation System (PECS). We find that PECS reverses the negative impact of strict ROOs on intermediate trade which turns positive as a consequence of introducing diagonal rules of cumulation (ROCs). -- Intermediate goods ; Rules of origin ; Rules of cumulation ; Firm heterogeneity, Gravity.

Book Description
"Measuring innovation is a challenging task, both for researchers and for national statisticians. This task is timely and valuable given that policy and public interest in innovation has become increasingly intense in this era of digital revolution, yet National GDP Accounts and other economic statistics do not fully account for the wide range of innovative activity that is plainly evident in everyday experience. Indeed, innovation has in many ways changed the structure of an increasingly digitized marketplace, from cloud computing to the gig economy. The papers collected in this volume, Measuring and Accounting for Innovation in the Twenty-First Century, address many different dimensions of this challenge, ranging from how to best to define GDP to the fundamental question of what is an innovation and how to collect data at the level of an individual innovation. Taken together, the volume provides a comprehensive overview of the cutting-edge of this widely varied but thematically-connected research that draws on multiple methodologies and data. The editors and authors consider how measurement frameworks could be expanded to enhance our understanding of innovative activity; new approaches and evidence that could account for innovation's economic impact; innovation's effect across the economy, from production processes to labor markets and financial activities; and what practical adjustments could be made to current measurements that would better capture innovation. The distinctive stance of this volume makes clear that the challenge of measuring innovation and understanding its implications has become increasingly complex as the economy has evolved. The editors and authors show that the limitations of our existing measurement system significantly hinder researchers, analysts, and policymakers. Better measures of innovative activity are necessary to interpret the consequences of innovation in daily life and to inform policies that best promote the attendant benefits, including distribution of income, trademark protections, and more. Now, in an era of fake news and alternative facts, it is more important than ever to push for accuracy in basic economic facts"--

Book Description
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.
