CERGE-EI Interviews Professor Dirk Engelmann

During Professor Engelmann’s visit to CERGE-EI, he sat down to speak with two PhD students for a brief interview. They discussed the direction of experimental economics, tips for getting a paper published, and the inspiration for research. Have a look at their interesting discussion:

On your CV we saw that you originally did a Masters in mathematics. Why did you decide to switch to economics?

I wanted to do something with somewhat more direct meaning towards life. Math was nice, but quite empty in some ways. Originally I planned to do my PhD in psychology. But I realized that the economists were a bit more open to introducing psychological ideas into experiments than psychologists were open to, for example, game theoretical modeling. If you do research with both psychology and economics, it seems easier to do it within economics, at least if you want to do it a bit more formally.

How do you get inspiration for your research?

There are three ways. One, I see some kind of theoretical or empirical paper, and I think ‘that’s worth testing’. Two, I see other experiments where I don’t quite trust results, and I want to do robustness checks. As for the third thing: I like to talk to people who don’t do experiments, because they often have questions that they’d like to test experimentally. If you talk to people who don’t do experiments, you are usually exposed to unusual questions, and you have to think about relatively innovative experiment designs.

Can you tell us what you think are the economic topics today which provide for ‘low hanging fruits’?

I think it’s hard to find ‘low hanging fruits’, because there are so many people doing experiments now. It is very attractive to start doing experiments, because it is a bit more entertaining than theoretical or empirical stuff. You can avoid some of the problems there. And you can be sure to get some kind of results. So I think that everything that looks like low hanging fruit is being constantly picked by these armies of experimentalists. Of course there are always some obvious questions that are not explored.

Understanding Development in Africa: An Interview with Dr. Nathan Fiala

Earlier this month, Dr. Nathan Fiala came to CERGE-EI to lecture about his research in Africa. The lecture was titled “Employment Generation in Rural Africa: Mid-term Results from an Experimental Evaluation of the Youth Opportunities Program in Northern Uganda.” Dr. Fiala sat down with CERGE-EI for a brief interview where he discussed his current research, the morals of sustainable development, and the expedience of experimental methods. Have a look!:


What research are you currently working on?

Right now I am doing randomized control trials. This is a big, new, exciting field.  In the last ten years it has become a special interest to a lot of developmental economists. I am conducting experiments in Africa, mostly in Uganda, but also India, and hopefully a few coming up in Kenya.

One that I’m working on right now is a ‘Cash Grant’ program, geared toward young men and women who are unemployed or underemployed in Uganda. The government has transferred money to them in order to help them set up businesses and gain some kind of employment and income generation.

There is a lot of unemployment and underemployment in Uganda, and very little formal sector employment. So for a lot of young people there, setting up their own business is basically the only option that they have. But there is doubt whether these types of ‘Cash Grant’ programs have any real impact, whether they provide any kind of meaningful help for individuals.

In order to explore this, we randomized who received the cash grant and who did not receive the cash grant. We did that because we wanted to try to compare those that received the cash grant with some kind of comparison group. It has to be a very well thought out comparison group, and randomization gives you the opportunity to basically ensure that with a large enough sample size. The people who receive the program versus those who do not receive it still have the same characteristics.  They’re about the same age on average, the same ratio of gender, the same education levels, etc. But most importantly they have the same level of excitement and interest in starting their own businesses.

Is there anything unique about doing research in Uganda?

Well one of the unique things about this is that it’s a program being conducted in a post-conflict area. It’s in Northern Uganda, which just finished a 20-year civil war. The government is interested in how to decrease the likelihood of civil unrest, violence, and proclivity to anti-social behavior. They hope these cash grant programs will cause citizens to become more productive citizens and less likely to engage in negative social behavior.
