Book Description
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

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.

Book Description
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.

Book Description
This book is open access under a CC BY-NC 4.0 license. This collected volume represents the final outcome of the COST Action IS1104 “The EU in the new complex geography of economic systems: models, tools and policy evaluation”. Visualizing the EU as a complex and multi-layered network, the book is organized in three parts, each of them dealing with a different level of analysis: At the macro-level, Part I considers the interactions within large economic systems (regions or countries) involving trade, workers migration, and other factor movements. At the meso-level, Part II discusses interactions within specific but wide-ranging markets, with a focus on financial markets and banking systems. Lastly, at the micro-level, Part III explores the decision-making of single firms, especially in the context of location decisions.

Book Description
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.
