For Fellow Teachers: Revised Primers on Linear Regression and Causality

If you teach in a policy school or in a political science department, chances are some of your students are not quite conversant in the quantitative methods used in the social sciences.

Many of the students who sign up for my fall seminar on the Microeconomics of International Development Policy or my spring seminar on Law, Economics and Organization, for example, are incredibly bright, but they are not familiar with regression analysis, and so they don’t know how to read a regression table. This makes it difficult to assign empirical papers in World Development for in-class discussion, let alone papers in the Journal of Development Economics.

While I do not have the time to teach basic econometrics to students in those seminars, I have prepared two handouts for them to read in preparation for reading papers containing empirical results, which I thought I should make available to anyone who would rather not spend precious class time teaching the basics of quantitative methods. I have used both these handouts in my development seminar last fall, and my students said that they had learned quite a bit from reading them.

Given that many of us are spending these days revising our syllabus for the fall semester, I have revised my empirical handouts for the new academic year, and I am happy to make them available to whoever wants to use them. If you use them, I simply request that you do not modify them and that you let me know about how I can improve them for next year.

Is Africa Leapfrogging PCs Like It Did Land Lines?

Forget pie-in-the-sky projects like One Laptop Per Child. That is essentially the message of this Forbes post by Tim Worstall:

“It can be true that a developing country should just skip an entire level or stage of economic development. For example, it’s now pretty certain that no African country is ever going to have a land line telephone network as do the industrialised countries. Building a mobile network is so much cheaper than sending wire to every house that that land line network is simply never going to be built.

Food and Politics in the Arab World

“We’re taught that domestic life is not a ‘serious’ political topic, like war and peace, but the fact is that we spend most of our lives doing everyday things: at the dinner table, in the kitchen, washing dishes, grocery shopping, commuting. These things make up the fabric of our lives. Americans are curious about the texture of everyday life in the Middle East because they rarely get to see it. I wanted readers to feel like they were sitting around the dinner table with me and my friends, hearing what average people really say and really think, [where] the dinner table is the best place to find out.
