February 2020A Method to Construct Geographical Crosswalks with an Application to US Counties since 1790
with Fabian Eckert, Andrés Gvirtz, Jack Liang: w26770
Empirical researchers often have to map data provided for a "reporting" spatial unit, say counties in 1900, to a "reference" one, say, counties in 2010. We discuss a general method to create such crosswalks: computing the share of the area of each reporting unit nested in a given reference unit. Using these shares, data can be re-aggregated from the reporting to the reference units. We apply the method to construct a crosswalk for US county-level data since 1790 to present-day counties or commuting zones. We also provide the code to generate other crosswalks given maps of reporting and reference units.
January 2016Lack of Selection and Limits to Delegation: Firm Dynamics in Developing Countries
with Ufuk Akcigit, Harun Alp: w21905
Managerial delegation is essential for firm growth. While firms in poor countries often shun outside managers and instead recruit among family members, the pattern is quite the opposite for firms in rich countries. In this paper, we ask whether these differences in managerial delegation have important aggregate effects. We construct a model of firm growth where entrepreneurs have fixed-time endowments to run their daily operations. As firms grow larger, the need to delegate decision-making authority increases. Firms in poor countries might therefore decide to remain small if delegating managerial tasks is difficult. We calibrate the model to firm-level data from the U.S. and India. We show that the model is quantitatively consistent with the experimental micro evidence on managerial effici...
August 2015The Gains from Input Trade in Firm-Based Models of Importing
with Joaquin Blaum, Claire LeLarge: w21504
Trade in intermediate inputs allows firms to lower their costs of production by using better, cheaper, or novel inputs from abroad. Quantifying the aggregate impact of input trade, however, is challenging. As importing firms differ markedly in how much they buy in foreign markets, results based on aggregate models do not apply. We develop a methodology to quantify the gains from input trade for a class of firm-based models of importing. We derive a sufficiency result: the change in consumer prices induced by input trade is fully determined from the joint distribution of value added and domestic expenditure shares in material spending across firms. We provide a simple formula that can be readily evaluated given the micro-data. In an application to French data, we find that consumer prices o...
