TLDR

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.read more

Analyses of Aggregate Fluctuation of Firm Network Based on Self-Organized Criticality Model and Control Theory.
TL;DR: The authors examined the difference in the size of avalanches among industries triggered by demand shocks, which can be rephrased by control of the economy or fiscal policy, and by using the production-inventory model and observed data.

A Dynamic Model of Input-Output Networks∗

TL;DR: In this article , the authors developed a dynamic model of input-output networks that incorporates adjustment costs of changing inputs and showed that temporary sectoral shocks have disproportionately significant welfare impact compared to affected sectors' Domar weights.

Production Networks Resilience: Cascading Failures, Power Laws and Optimal Interventions
TL;DR: In this article , the authors study the severity of cascading failures in supply chain networks defined by a node percolation process corresponding to product suppliers failing independently due to systemic shocks.

Emergence of Scaling in Random Networks
TL;DR: A model based on these two ingredients reproduces the observed stationary scale-free distributions, which indicates that the development of large networks is governed by robust self-organizing phenomena that go beyond the particulars of the individual systems.

Time to build and aggregate fluctuations
TL;DR: In this article, a general equilibrium model is developed and fitted to U.S. quarterly data for the post-war period, with the assumption that more than one time period is required for the construction of new productive capital and the non-time-separable utility function that admits greater intertemporal substitution of leisure.

Probability: Theory and Examples
TL;DR: In this paper, a comprehensive introduction to probability theory covering laws of large numbers, central limit theorem, random walks, martingales, Markov chains, ergodic theorems, and Brownian motion is presented.
