摘要：Industrial agglomeration policies may limit competition. We develop, validate, and apply a novel approach for measuring competition based on the comovement of markups and market shares among firms in the same location and industry. Then we develop a model of how this reduction in competition affects aggregate income. We apply our approach to the well-known special economic zones (SEZs) of China. We estimate that firms in SEZs exhibit cooperative pricing almost three times as intensively as fir...

摘要：We use sizable lottery prizes in Norwegian administrative panel data to explore how transitory income shocks are spent and saved over time and how households' marginal propensities to consume (MPCs) vary with household characteristics and shock size. We find that spending peaks in the year of winning and gradually reverts to normal within five years. Controlling for all items on households' balance sheets and characteristics such as education and income, it is the amount won, age, and liquid a...

摘要：To quantify trade frictions, we examine -multiproduct exporters. We build a flexible general-equilibrium model and estimate market entry costs using Brazilian firm-product-destination data under rich demand and market access cost shocks. Our estimates show that additional products farther from a firm's core competency come at higher production costs, but there are substantive economies of scope in market access costs. Market access costs differ across destinations, falling more rapidly in scop...

摘要：Firm-level, revenue-based productivity measures are ubiquitous in studies of firm dynamics and aggregate outcomes. One common measure is increasingly interpreted as reflecting distortions since in distortions' absence, equalization of marginal revenue products should yield no dispersion in this measure. Another common but distinct measure is the residual of the -firm-level revenue function, which reflects fundamentals. Using-micro-level US manufacturing data, we find these alternative measures...
