Structural Change in Labor Supply and Cross-Country Differences in Hours Worked

This paper studies how structural change in labor supply along the development spectrum shapes cross-country differences in hours worked. We emphasize two main forces: sectoralreallocation from self-employment to wage work, and declining fixed costs of wage work. We show that these forces are crucial for understanding how the extensive margin (the employment rate) and intensive margin (hours per worker) of aggregate hours worked vary with income per capita. To do so we build and estimate a quantitative model of labor supply featuring a traditional self-employment sector and a modern ...

State Capacity and Public Goods: Institutional Change, Human Capital, and Growth in Early Modern Germany

What are the origins and consequences of the state as a provider of public goods? We study legal reforms that established mass public education and increased state capacity in German cities during the 1500s. These fundamental changes in public goods provision occurred where ideological competition during the Protestant Reformation interacted with popular politics at the local level. We document that cities that formalized public goods provision in the 1500s began differentially producing and attracting upper tail human capital and grew to be significantly larger in the long-run. We study ...

Structural Change in Sub-Saharan Africa: An Open Economy Perspective

We study the evolution of manufacturing value added shares in 11 sub-Saharan African (SSA) countries through the lens of an open economy model of structural change. Our analysis leverages recent developments in input-output tables in SSA countries. Our model allows for income effects via non-homothetic preferences, substitution and relative price effects, as well as comparative advantage and specialization effects. We calibrate our model to include each SSA country with nine other major economies for each year between 2000 and 2018. We also do a similar set of calibrations for 11 developing ...

Modernization and Discrete Measures of Democracy

We reassess the empirical evidence for a positive relationship between income and democracy, commonly known as the ?modernization hypothesis,? using discrete democracy measures. While discrete measures have been advocated in the literature, they pose estimation problems under fixed effects due to incidental parameter issues. We use two methods to address these issues, the bias-correction method of Fernandez-Val, which directly computes the marginal effects, and the parameterized Wooldridge method. Estimation under the Fernandez-Val method consistently indicates a statistically and ...

Capital Accumulation and Dynamic Gains from Trade

We compute welfare gains from trade in a dynamic, multicountry model with capital accumulation. We examine transition paths for 93 countries following a permanent, uniform, unanticipated trade liberalization. Both the relative price of investment and the investment rate respond to changes in trade frictions. Relative to a static model, the dynamic welfare gains in a model with balanced trade are three times as large. The gains including transition are 60 percent of those computed by comparing only steady states. Trade imbalances have negligible effects on the cross-country distribution of ...

Trade Risk and Food Security

We study the role of international trade risk for food security, the patterns of production and trade across sectors, and its implications for policy. We document that food import dependence across countries is associated with higher food insecurity, particularly in low-income countries. We provide causal evidence on the role of trade risk for food security by exploiting the exogeneity of the Ukraine-Russia war as a major trade disruption limiting access to imports of critical food products. Using micro-level data from Ethiopia, we empirically show that districts relatively more exposed to ...

The Labor Market Consequences of Appropriate Technology

Developing countries rely on technology created by developed countries. This paper demonstrates that such reliance increases wage inequality but leads to greater production in developing countries. I study a Brazilian innovation program that taxed the leasing of international technology to subsidize national innovation. I show that the program led firms to replace technology licensed from developed countries with in-house innovations, which led to a decline in both employment and the share of high-skilled workers. Using a model of directed technological change and technology transfer, I find ...

Institutions Do Not Rule: Reassessing the Driving Forces of Economic Development

The pursuit to uncover the driving forces behind cross-country income gaps has divided economists into two major camps: One emphasizes institutions, while the other stresses non-institutional forces such as geography. Each school of thought has its own theoretical foundation and empirical support, but they share an implicit hypothesis?the forces driving economic development remain the same regardless of a country?s stage of development. Such hypothesis implies a theory that the process of development in human history is a continuous improvement in income levels, driven by the same forces, and ...

Natural Resources and Global Misallocation

We explore the efficiency in the allocation of physical capital and human capital across countries. The observed marginal products can differ across countries because of differences in technology (i.e. production functions) and in distortions (i.e. differences in use of factors) across countries. To identify differences in technology, we use new data and propose a simple method to estimate output shares of natural resources, and thus adjust the estimated marginal products of physical and human capital. With a sample of 79 countries from 1970 to 2005, we find that the world has decidedly moved ...

Human Capital and Development Accounting: New Evidence from Wage Gains at Migration

We use new data on the pre- and post-migration wages of U.S. immigrants to measure the importance of human capital for development accounting. Wages increase at migration, but by less than half of the gap in GDP per worker. This finding implies that human capital accounts for a large share of cross-country income differences. Wage gains decline with education, consistent with imperfect substitution between skill types. We bound the human capital share in development accounting to between one-half and two-thirds; additional assumptions lead to an estimate of 60 percent. We also provide results ...
