Making Sense of Africa's Infrastructure Endowment: A Benchmarking Approach

The papers objective is to explain factors underlying Africas weak infrastructure endowment and to identify suitable infrastructure goals for the region based on benchmarking against international peers. The authors use a dataset covering the stocks of key infrastructure-including information and communication technology (ICT), power, roads, and water-across 155 developing countries over the period 1960 to 2005. The paper also examines subregional differences within Africa. They make use of regression techniques to control for a comprehensive set of economic, demographic, geographic, and historic conditioning factors, as well as adjusting for potential endogeneities. Results show that Africa lags behind all other regions of the developing world in its infrastructure endowment, except in ICT. By far the largest gaps arise in the power sector, with generating capacity and household access to electricity at half the levels observed in South Asia. While it is often assumed that Africas infrastructure deficit is largely a reflection of its relatively low income levels, the authors find that African countries have much more limited infrastructure than income peers in other parts of the developing world. Countries that face the most challenging environment, with low population density, weak governance, and history of conflict, have the poorest infrastructure endowments. At the outset of the data series, Africa was doing significantly better than other developing regions for road density, generation capacity, and fixed-line telephones, but Africas relative position has deteriorated over time. The most dramatic loss of ground has come in electrical generating capacity, which has stagnated since 1980.

Trade Liberalization and Mortality: Evidence from U.S. Counties

We investigate the impact of a large economic shock on mortality. We find that counties more exposed to a plausibly exogenous trade liberalization exhibit higher rates of suicide and related causes of death, concentrated among whites, especially white males. These trends are consistent with our finding that more-exposed counties experience relative declines in manufacturing employment, a sector in which whites and males are disproportionately employed. We also examine other causes of death that might be related to labor market disruption and find both positive and negative relationships. More-exposed counties, for example, exhibit lower rates of fatal heart attacks.

Evidence for the Effects of Mergers on Market Power and Efficiency

Study of the impact of mergers and acquisitions (M&As) on productivity and market power has been complicated by the difficulty of separating these two effects. We use newly-developed techniques to separately estimate productivity and markups across a wide range of industries using detailed plant-level data. Employing a difference-in-differences framework, we find that M&As are associated with increases in average markups, but find little evidence for effects on plant-level productivity. We also examine whether M&As increase efficiency through reallocation of production to more efficient plants or through reductions in administrative operations, but again find little evidence for these channels, on average. The results are robust to a range of approaches to address the endogeneity of firms’ merger decisions.

Antidumping Duties and Plant-Level Restructuring

This paper examines the effect of antidumping duties on the restructuring activities of protected plants. Using a dataset that contains the full population of U.S. manufacturers, I find that protected plants increase their capital intensities modestly relative to unprotected plants, but only when antidumping duties have been in place for a sufficient duration. I find little effect of antidumping duties on a proxy for the skilled labor intensity of protected plants.
