The authors propose a new method for estimating the power-law exponents of firm size variables. Their focus is on how to empirically identify a range in which a firm size variable follows a power-law distribution. On the one hand, as is well known a firm size variable follows a power-law distribution only beyond some threshold. On the other hand, in almost all empirical exercises, the right end...

Abstract We construct a tractable neoclassical growth model that generates Pareto’s law of income distribution and Zipf’s law of firm size distribution from idiosyncratic, firm-level productivity shocks. CEOs invest in risk-free assets as well as their own firms’ risky stocks, through which their assets and incomes depend on firm-level shocks. Using the model, we evaluate how changes in tax rat...

We analyze the size dependence and temporal stability of firm bankruptcy risk in the US economy by applying Zipf scaling techniques. We focus on a single risk factor--the debt-to-asset ratio R--in order to study the stability of the Zipf distribution of R over time. We find that the Zipf exponent increases during market crashes, implying that firms go bankrupt with larger values of R. Based on ...

Using firm-level data from India, this paper investigates the distributional effects of deregulation on firm size and profitability. The data suggest that average firm size declines significantly in industries that deregulated entry. Firm entry leads occurs from the left hand tail of the size distribution with more small firms entering the market while the largest incumbent firms get significan...

Recently there has been a renewed interest in the study of firm size distributions and firm growth rate distributions. The stochastic firm growth approach builds on the assumption that firm growth rates are independent identically distributed and size is determined by a first order autoregressive process leaving the size distribution log-normal. This paper analyzes these distributional patterns...

Motivated by theories of the rm, which we classify as \technological" or \organizational", we analyze the determinants of rm size across industries and across countries in a sample of 15 European countries. We nd that, on average, rms facing larger markets are larger. At the industry level, we nd rms in the utility sector are large, perhaps because they enjoy a natural, or o cially sanctioned, ...

a study of the atmospheric particulate size distribution of total suspended particulate matter(tspm) and associated heavy metals concentrations has been carried out for the urban part of sarajevo city,bosnia and herzegovina. urban particles (n=150) were collected using a high volume air sampler equippedwith a 6-stage impactor. apart from fe which has been determined by flame atomic absorption s...

dissolution pressure and nozzle temperature effects on particle size and distribution were investigated for ress (rapid expansion of supercritical solution) process. supercritical co2 was used as solvent and ibuprofen was applied as the model component in all runs. the resulting ibuprofen nano-particles (about 50 nm in optimized runs) were analyzed by sem and laser diffraction particle size ana...
