Book Description
This paper uses a database covering the universe of French firms for the period 1990--2007 to provide a forensic account of the role of individual firms in generating aggregate fluctuations. We set up a simple multi-sector model of heterogeneous firms selling to multiple markets to motivate a theoretically-founded decomposition of firms' annual sales growth rate into different components. We find that the firm-specific component contributes substantially to aggregate sales volatility, mattering about as much as the components capturing shocks that are common across firms within a sector or country. We then decompose the firm-specific component to provide evidence on two mechanisms that generate aggregate fluctuations from microeconomic shocks highlighted in the recent literature: (i) when the firm size distribution is fat-tailed, idiosyncratic shocks to large firms directly contribute to aggregate fluctuations; and (ii) aggregate fluctuations can arise from idiosyncratic shocks due to input-output linkages across the economy. Firm linkages are approximately three times as important as the direct effect of firm shocks in driving aggregate fluctuations.

Firms, Destinations, and Aggregate Fulctuations
Entry, Exit, Firm Dynamics, and Aggregate Fluctuations
Author: Gian Luca Clementi
Publisher:
ISBN:
Category : Economics
Languages : en
Pages :
Book Description
Do firm entry and exit play a major role in shaping aggregate dynamics? Our answer is yes. Entry and exit propagate the effects of aggregate shocks. In turn, this results in greater persistence and unconditional variation of aggregate time-series. These are features of the equilibrium allocation in Hopenhayn (1992)'s model of equilibrium industry dynamics, amended to allow for investment in physical capital and aggregate fluctuations. In the aftermath of a positive productivity shock, the number of entrants increases. The new firms are smaller and less productive than the incumbents, as in the data. As the common productivity component reverts to its unconditional mean, the new entrants that survive become more productive over time, keeping aggregate efficiency higher than in a scenario without entry or exit.

Idiosyncratic Shocks and Aggregate Fluctuations in an Emerging Market
Author: Mr. Francesco Grigoli

Pages : 20
Book Description
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.

Heterogeneous Firms and the Micro Origins of Aggregate Fluctuations
Firm-specific Shocks and Aggregate Fluctuations

Category : Business cycles
Languages : en
Pages : 15
Book Description
"In order to understand what drives aggregate fluctuations, many macroeconomic models point to aggregate shocks and discount the contribution of firm-specific shocks. Recent research from other developed countries, however, has found that aggregate fluctuations are in part driven by idiosyncratic shocks to large firms. Using data on Canadian firms, this paper examines the contribution of large firms to industry-level fluctuations in gross output, investment and employment in the manufacturing sector. The data suggest that shocks to large firms can explain as much as 46% and 37% of the fluctuations in gross output and investment, respectively, but do not contribute to fluctuations in employment"--Abstract.

Firm Dynamics and the Origins of Aggregate Fluctuations
Aggregate Fluctuations and the Cross-sectional Dynamics of Firm Growth
The Granular Origins of Macroeconomic Fluctuations in Europe
Author: Mr.Christian H Ebeke
Publisher: International Monetary Fund
ISBN: 1484326997
Category : Business & Economics
Languages : en
Pages : 33
Book Description
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.
