Available in PDF, EPUB and Kindle. Book excerpt: Abstract: This paper proposes that idiosyncratic firm-level fluctuations can explain an important part of aggregate shocks, and provide a microfoundation for aggregate productivity shocks. Existing research has focused on using aggregate shocks to explain business cycles, arguing that individual firm shocks average out in aggregate. I show that this argument breaks down if the distribution of firm sizes is fat-tailed, as documented empirically. The idiosyncratic movements of the largest 100 firms in the US appear to explain about one third of variations in output and the Solow residual. This "granular" hypothesis suggests new directions for macroeconomic research, in particular that macroeconomic questions can be clarified by looking at the behavior of large firms. This paper's ideas and analytical results may also be useful to think about the fluctuations of other economic aggregates, such as exports or the trade balance

This book was released on 2017-11-07 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper investigates the microeconomic origins of aggregate economic fluctuations in Europe. It examines the relevance of idiosyncratic shocks at the top 100 large firms (the granular shocks) in explaining aggregate macroeconomic fluctuations. The paper also assesses the strength of spillovers from large firms onto SMEs. Using firm-level data covering over 14 million firms and eight european countries (Austria, Belgium, Finland, France, Germany, Italy, Portugal and Spain), we find that: (i) 40 percent of the variance in GDP in the sample can be explained by idiosyncratic shocks at large firms; (ii) positive granular shocks at large firms spill over to domestic SMEs’ output, especially if SMEs’ balance sheets are healthy and if SMEs belong to the services and manufacturing sectors.

Available in PDF, EPUB and Kindle. Book excerpt: We study the aggregate implications of sectoral shocks in a multi-sector New Keynesian model featuring sectoral heterogeneity in price stickiness, sector size, and input-output linkages. We calibrate a 341 sector version of the model to the United States. Both theoretically and empirically, sectoral heterogeneity in price rigidity (i) generates sizable GDP volatility from sectoral shocks, (ii) amplifies both the "granular" and the "network" effects, (iii) alters the identity and relative contributions of the most important sectors for aggregate fluctuations, (iv) can change the sign of fluctuations, (v) invalidates the Hulten Theorem, and (vi) generates a frictional origin of aggregate fluctuations.

This book was released on 2021-12-10 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper provides the first assessment of the contribution of idiosyncratic shocks to aggregate fluctuations in an emerging market using confidential data on the universe of Chilean firms. We find that idiosyncratic shocks account for more than 40 percent of the volatility of aggregate sales. Although quite large, this contribution is smaller than documented in previous studies based on advanced economies, despite a higher degree of market concentration in Chile.We show that this finding is explained by larger firms being less volatile and by weaker propagation effects across Chilean firms.

Download or read book ASEAN 5 Further Harnessing the Benefits of Regional Integration Amid Fragmentation Risks written by Nuri Baek and published by International Monetary Fund. This book was released on 2023-09-15 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ASEAN-5 region, which comprises Indonesia, Malaysia, the Philippines, Singapore, and Thailand, has benefited substantially from its integration to the world economy, particularly through trade. Rising risks of geoeconomic fragmentation could reverse some gains reaped from globalization over the past decades. In this context, advancing regional integration among ASEAN-5 members has the potential to enhance the region’s resilience against external headwinds. This paper shows that despite sizeable progress, particularly in regional trade integration, there is room to advance financial integration, which also lags trade integration in ASEAN-5. Empirical findings from the paper illustrate that a higher degree of regional financial integration could generate sizeable output gains for the region. Using firm-level data, the paper highlights that digitalization, an area where the region is thriving, can support regional integration by helping firms better integrate into global value chains, with the benefits being stronger for small and medium sized enterprises. The results also suggest that digitalization can help firms move up the value chain through the production of more sophisticated products, often coined as higher export sophistication.

Download or read book Rethinking Macroeconomics with Endogenous Market Structure written by Marco Mazzoli and published by Cambridge University Press. This book was released on 2019-12-19 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: The birth and death of firms is one of the main features of the business cycle. Yet mainstream DGSE macroeconomic models mostly ignore this phenomenon, thereby excluding any potential impact of economic policy on the probability of the birth and death of firms. Those DGSE models that do allow for this phenomenon do so at the cost of drastic simplifications, which effectively rule out causal links between the strategic interaction of industrial firms and the macroeconomy. This innovative new book develops a bottom-up, agent-based framework that shows how strategic interactions at the level of oligopolistic firms, and even at the level of individuals, affect entire industrial sectors and the equilibrium of the macroeconomy. It will appeal to academic researchers and graduate students working in computational economics, agent-based modelling and econophysics, as well as mainstream economists interested in learning more about alternatives to DGSE models in macroeconomics.

Download or read book Networks written by Sanjeev Goyal and published by MIT Press. This book was released on 2023-04-18 with total page 823 pages. Available in PDF, EPUB and Kindle. Book excerpt: An accessible and comprehensive overview of the economic theory and the realities of networks written by a pioneering economics researcher. Networks are everywhere: the infrastructure that brings water into our homes, the social networks made up of our friends and families, the supply chains connecting cities, people, and goods. These interconnections contain economic trade-offs: for example, should an airline operate direct flights between cities or route all its flights through a hub? Viewing networks through an economics lens, this textbook considers the costs and benefits that govern their formation and functioning. Networks are central to an understanding of the production, consumption, and information that lie at the heart of economic activity. Sanjeev Goyal provides advanced undergraduate and graduate students with an accessible and comprehensive introduction to the economics research on networks of the past twenty-five years. Each chapter introduces a theoretical model illustrated with the help of case studies and formal proofs. After introducing the theoretical concepts, Goyal examines economic networks, including infrastructure, security, market power, and financial networks. He then covers social networks, with chapters on coordinating activity, communication and learning, information networks, epidemics, and impersonal markets. Finally, Goyal locates social and economic networks in a broader context covering networked markets, economic development, trust, and group networks in their relation to markets and the state. First textbook to provide a broad and comprehensive overview of twenty-first-century economic theory of networks Features engaging case studies and accessible exercises Written by a pioneering economics researcher

Download or read book Schumpeter s Venture Money written by Michael Peneder and published by Oxford University Press. This book was released on 2021-02-04 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Distinctively tying history with theory, political economist Joseph A. Schumpeter reached far back in time to understand what drives economic development and determines its course. Historical and empirical research provided a laboratory for learning. At the same time, he reached for a long-term vision through theoretical inspection and utmost abstraction, seeking to distil a phenomenon's essential nature and function. He believed that good theory can indicate where the economy is headed in the future. Schumpeter's attention to history and theory also informed the plan for this book. Part I trails the historical stream of financial innovations and the scholarly struggle to assimilate them in monetary thought, while Part II focuses on Schumpeter's own monetary theory. Its deliberate reconstruction from scattered sources reveals a strikingly original and still modern conception. Drawing from the detailed study of documents at various archives in Austria, Part III then concentrates on the business history of Schumpeter's failed personal endeavours in banking and as a proto-venture capitalist. Finally, Part IV casts light on the legacy of Schumpeter's monetary ideas on contemporary thought. It depicts how monetary theory initially left them behind, yet has more recently set out to return to his ideas on money, financial innovation, and growth. Overall, a surprisingly coherent picture emerges from the study of Schumpeter's neglected monetary theory, his personal history, and his intellectual legacy on the present day.

Download or read book Economics with Heterogeneous Interacting Agents written by Alessandro Caiani and published by Springer. This book was released on 2016-09-21 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a practical guide to Agent Based economic modeling, adopting a “learning by doing” approach to help the reader master the fundamental tools needed to create and analyze Agent Based models. After providing them with a basic “toolkit” for Agent Based modeling, it present and discusses didactic models of real financial and economic systems in detail. While stressing the main features and advantages of the bottom-up perspective inherent to this approach, the book also highlights the logic and practical steps that characterize the model building procedure. A detailed description of the underlying codes, developed using R and C, is also provided. In addition, each didactic model is accompanied by exercises and applications designed to promote active learning on the part of the reader. Following the same approach, the book also presents several complementary tools required for the analysis and validation of the models, such as sensitivity experiments, calibration exercises, economic network and statistical distributions analysis. By the end of the book, the reader will have gained a deeper understanding of the Agent Based methodology and be prepared to use the fundamental techniques required to start developing their own economic models. Accordingly, “Economics with Heterogeneous Interacting Agents” will be of particular interest to graduate and postgraduate students, as well as to academic institutions and lecturers interested in including an overview of the AB approach to economic modeling in their courses.

Download or read book Power Laws in Firm Size and Openness to Trade written by Mr.Andrei A. Levchenko and published by International Monetary Fund. This book was released on 2010-04-01 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Financial Shock Transmission to Heterogeneous Firms The Earnings Based Borrowing Constraint Channel written by Livia Chiţu and published by International Monetary Fund. This book was released on 2023-09-15 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: We study the heterogeneous impact of jointly identified monetary policy and global risk shocks on corporate funding costs. We disentangle these two shocks in a structural Bayesian Vector Autoregression framework and investigate their respective effects on funding costs of heterogeneous firms using micro-data for the US. We tease out mechanisms underlying the effects by contrasting traditional financial frictions arising from asset-based collateral constraints with the recent earnings-based borrowing constraint hypothesis, differentiating firms across leverage and earnings. Our empirical evidence strongly supports the earnings-based borrowing constraint hypothesis. We find that global risk shocks have stronger and more heterogeneous effects on corporate funding costs which depend on firms' position within the earnings distribution.
