A generation ago, the World Development Report 1984 focused on development challenges posed by demographic change, reflecting the world’s concerns about run-away population growth. Global population growth rates had peaked at more than two percent a year in the late 1960s and the incredibly high average fertility rates of that decade – almost six births per woman – provided the momentum to keep population growth rates elevated for several decades (Fig 1). Indeed, the population and development zeitgeist spawned works such as Ehrlich’s 1968 book “Population Bomb,” which painted apocalyptic images of a world struggling to sustain itself under the sheer weight of its people. The policy discussion of the WDR 1984 reflected these concerns, focusing on how to feed the growing populations in the poorest and highest fertility countries, while also presenting a case for policies that would reduce fertility.
Migration and Remittances
Do migrants respond to differences in access to public goods and services in addition to income prospects of potential destinations? This issue is important in developing countries where provision of basic public goods affects not only income prospects but also quality of life. And in these countries, provision of public goods tends to vary widely across areas. In a Tiebout (1956) sorting model, such disparity in the provision of public goods such as roads, electricity, schools, hospitals, etc. should induce people to "vote with their feet" and to migrate to areas with better access to these infrastructures and services.
Equitablog, run by the Washington Center for Equitable Growth, has launched a series of 'Notes and Finger Exercises on Thomas Piketty’s “Capital in the Twenty-First Century”.' Brad DeLong's post, 'There Are Four r’s', details some alleged oversights in Piketty's book. In particular, DeLong focuses on how the real interest rate behaves at different levels of economic activity. He highlights Larry Summers' concern about secular stagnation and the risk that rich folks might retreat from investing in industry. And DeLong pulls out some sexy math.
Matthew Gentzkow has won the John Bates Clark Medal, an honor conferred by the American Economic Association for his contributions to "our understanding of the economic forces driving the creation of media products, the changing nature and role of media in the digital environment, and the effect of media on education and civic engagement..."
For those of you who are not interested in soccer and for our young colleagues who are growing up with Messi and Ronaldo: Johan Cruijff was the best soccer player ever. At least according to his Dutch fans; skeptics can convince themselves here. As a player and coach he has won every conceivable prize for club teams, but he has become even more famous as an analyst. His judgments are so inscrutable for mere earthlings that his utterings are considered without exception as deep philosophical wisdoms. One of his more transparent quotes might give you already an impression: Soccer is simple, but it is difficult to play simple soccer. There must be deep insight also in Italians can't win the game against you, but you can lose the game against the Italians. People have collected over the years many more examples, but I want to discuss one of his more recent observations.
