October 2017Vertical Integration, Supplier Behavior, and Quality Upgrading among Exporters
with Christopher Hansman, Gianmarco León, Matthieu Teachout: w23949
We study the relationship between firms’ output quality and their choice of organizational structure. To do so, we use data on each step of the production and transaction chain that makes up Peruvian fishmeal manufacturing. We first show that quality upgrading is an important motive for vertically integrating. Firms integrate suppliers when the quality premium—the relative price of high quality output—rises for exogenous reasons, but not when average or low quality prices rise. The greater a firm’s scope for shifting low to high quality production, the greater its integration response. We then show that integration changes suppliers’ production behavior. A given supplier’s actions are less geared towards increasing quantity and more geared towards maintaining input quality after the suppli...
July 2017The Arrival of Fast Internet and Employment in Africa
with Jonas Poulsen: w23582
To show how fast Internet affects employment in Africa, we exploit the gradual arrival of submarine Internet cables on the coast and maps of the terrestrial cable network. Robust difference-in-differences estimates from three datasets covering 12 countries show large positive effects on employment rates—also for less educated worker groups—with little or no job displacement across space. The sample-wide impact is driven by increased employment in higher-skill occupations, but less educated workers’ employment gain less so. Firm level data available for some countries indicate that increased firm entry, productivity, and exporting contribute to higher net job-creation. Average incomes rise.
April 2017Individuals and Organizations as Sources of State Effectiveness, and Consequences for Policy
with Michael Carlos Best, David Szakonyi: w23350
How much of the variation in state effectiveness is due to the individuals and organizations responsible for implementing policy? We investigate this question and its implications for policy design in the context of public procurement, using a text-based product classification method to measure bureaucratic output. We show that effective procurers lower bid preparation/submission costs, and that 60% of within-product purchase-price variation across 16 million purchases in Russia in 2011-2015 is due to the bureaucrats and organizations administering procurement processes. This has dramatic policy consequences. To illustrate these, we study a ubiquitous procurement policy: bid preferences for favored firms (here domestic manufacturers). The policy decreases overall entry and increases prices...
