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 ...
The Role of Innovations in Global Trade: The Shipping Container
A simple trade innovation—the use of shipping containers—may have contributed to the rapid expansion of global trade over the past 50 years.

A Theory of Economic Unions: A Comment
Gino Gancia, Giacomo Ponzetto and Jaume Ventura have written an extremely interesting paper on a topic that is very timely for the global economy. In this article, I will first argue that GPV have succeeded in formalizing their hypothesis, and that while providing very suggestive analytical results, additional work can and should be done with the model, especially with regards to relative changes in the relative weights of incumbent countries. Second, I will comment on the potential insights if the rest of the world is modeled more realistically. Third, I will call for extending the baseline ...

Student Loans Under the Risk of Youth Unemployment
While most college graduates eventually find jobs that match their qualifications, the possibility of long spells of unemployment and/or underemployment?combined with ensuing difficulties in repaying student loans?may limit and even dissuade productive investments in human capital. The author explores the optimal design of student loans when young college graduates can be unemployed and reaches three main conclusions. First, the optimal student loan program must incorporate an unemployment compensation mechanism as a key element, even if unemployment probabilities are endogenous and subject ...

Education Policies and Structural Transformation
This article studies the impact of education and fertility in structural transformation and growth. In the model there are three sectors, agriculture, which uses only low-skill labor, manufacturing, that uses high-skill labor only and services, that uses both. Parents choose optimally the number of children and their skill. Educational policy has two dimensions, it may or may not allow child labor and it subsidizes education expenditures. The model is calibrated to South Korea and Brazil, and is able to reproduce some key stylized facts observed between 1960 and 2005 in these economies, such ...

Natural Resources and Global Misallocation
Are production factors allocated efficiently across countries? To differentiate misallocation from factor intensity differences, we provide a new methodology to estimate output shares of natural resources based solely on current rent flows data. With this methodology, we construct a new dataset of estimates for the output shares of natural resources for a large panel of countries. In sharp contrast with Caselli and Feyrer (2007), we find a significant and persistent degree of misallocation of physical capital. We also find a remarkable movement toward efficiency during last 35 years, ...

Shifting Times: The Evolution of the American Workplace
We explore the substantial shifts in the American labor force and workplace over almost 70 years, showing that the identity, education, race and occupations of the average American worker have all been changing. We document big changes in the types of jobs being done by American workers and on the assignment of jobs across workers with different educational levels and other characteristics. Regardless of how much more challenging labor markets become for everyone, the aggregate productivity is higher when the country takes advantage of the talent of all the demographic groups and not just a ...

Student Loans and Repayment: Theory, Evidence and Policy
Rising costs of and returns to college have led to sizeable increases in the demand for student loans in many countries. In the U.S., student loan default rates have also risen for recent cohorts as labor market uncertainty and debt levels have increased. We discuss these trends as well as recent evidence on the extent to which students are able to obtain enough credit for college and the extent to which they are able to repay their student debts after. We then discuss optimal student credit arrangements that balance three important objectives: (i) providing credit for students to access ...
