Much of the debate about the effects of immigration on native workers focuses on possible negative consequences for wages or employment. However, a series of recent papers highlights a big positive effect – having immigrants as cleaners, nannies, and home-care assistants allows high-skilled women to work more.
Given the massive debate in the U.S. about government health insurance, the just released results of a new experiment are justly making headlines. In 2004, the state of Oregon, due to budgetary shortfalls, closed its public health insurance program for low-income people. In early 2008, the state decided it had enough budget to fund 10,000 new spots. Given that it expected demand for these new slots to far exceed supply, the state Government opened up a sign-up window, getting 90,000 people to sign-up for a waitlist, and then used random lottery draws to select people from the waitlist.
Happy 4th of July. Believe it or not, there is a recent paper which aims to estimate the impact of celebrating this holiday. Here’s the abstract: “Do childhood events shape adult political views and behavior? This paper investigates the impact of Fourth of July celebrations in the US during childhood on partisanship and participation later in life.
That’s one blunt message from my new working paper with Marcel Fafchamps, Simon Quinn and Chris Woodruff, which replicates in Ghana a study that Chris and I had previously done in Sri Lanka with Suresh de Mel. In the new experiment, we take almost 800 microenterprises in urban Ghana, and randomly divide them into treatment and control groups.

Studying abroad is becoming increasingly common in many countries – with almost 3 million students educated each year at the tertiary level in a country other than their own. For developing countries in particular, studying abroad offers many of the promises and fears of brain drain (both of which I think are overblown).
Berk (who is on vacation this week) and I have recently been surveying assistant professors, graduate students, and World Bank economists to learn how they find out about new research and the role of blogs in this process. We’ll be sharing results once we have finished this, but to start with, I thought I’d share this chart below on what junior faculty who work on development think are the under-researched topics.
- The big picture
A number of recent field experiments have been conducted within firms and across firms. In another paper in what is shaping up to be an excellent forthcoming Journal of Economic Perspectives symposia on experiments, Oriana Bandiera,Iwan Barankay and Imran Rasul give their take of what we have learned from firm experiments so far, and their ideas on further research directions.
