October 2017Vertical Integration, Supplier Behavior, and Quality Upgrading among Exporters
with Christopher Hansman, Gianmarco León, Matthieu Teachout: w23949
We study the relationship between exporters' organizational structure and output quality. If only input quantity is observable, theory predicts that vertical integration may be necessary to incentivize suppliers to increase input quality. Using data on suppliers' behavior, supplier ownership, supply transactions, and manufacturers' output by quality grade and exports from the Peruvian fishmeal industry, we show the following. After integrating with the plant being supplied and losing access to alternative pay-per-kilo buyers, suppliers take more quality-increasing and less quantity-increasing actions. Integration consequently causally increases output quality, and manufacturers integrate suppliers when facing high relative demand for high quality grades.
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 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, with little job displacement across space. A decrease in workers’ likelihood of holding unskilled jobs is offset by a bigger increase in employment in higher-skill occupations. Less educated workers’ employment rate also rises. Firm level data available for some countries indicate that increased firm entry, productivity, and exporting lead to higher job-creation (and/or -saving). Average incomes and wealth 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...
