Enumerators play a crucial role in the success of field-based impact evaluations. Despite the central role they play in the research process, enumerators are rarely in the spotlight. We recently interviewed a few Innovations for Poverty Action (IPA) enumerators working with us on a high-frequency market survey in Rwanda in the context of a rural feeder road upgrading project.
This is the ninth in this year's series of posts by PhD students on the job market.
In low-income countries, small firms account for the majority of taxpayers (World Bank 2011). Yet we know little about how they navigate taxation. Existing research in the developing world focuses mostly on middle-income countries (Pomeranz 2015; Best et al. 2015; Brockmeyer and Hernandez 2018), and there is good reason to think that the tax behavior of firms in the world’s poorest countries might look different. On the one hand, higher credit constraints may undermine entrepreneurs’ ability to meet their tax obligations. On the other, limited resources for tax oversight might create gaps in enforcement that allow firms to evade taxes more easily.
The question of how such firms respond to taxes is a consequential one. It matters both for governments’ ability to raise revenues, in places where funds are much-needed, and for the take-home earnings of large populations of poor entrepreneurs.
My job market paper explores how small firms in Rwanda respond to a change in tax incentives. Rwanda provides a useful setting to study small firms’ tax behavior because such firms comprise 99% of all taxpayers. Rwanda is also a representative low-income country, ranking as 18th poorest in the world (IMF 2018). I focus on entrepreneurs that are earning less than USD $4,000 per year.
In Gaile Parkin's novel Baking Cakes in Kigali, two women living in Kigali, Rwanda – Angel and Sophie – argue over the salary paid to a development worker: "Perhaps these big organisations needed to pay big salaries if they wanted to attract the right kind of people; but Sophie had said that they were the wrong kind of people if they would not do the work for less. Ultimately they had concluded that the desire to make the world a better place was not something that belonged in a person's pocket. No, it belonged in a person's heart."
It's not a leap to believe – like Angel and Sophie – that teachers should want to help students learn, health workers who want help people heal, and other workers in service delivery should want to deliver that service. But how do you attract and motivate those passionate public servants? Here is some recent research that sheds light on the topic.
Many important policies are implemented at the national level. Monetary policy, fiscal policy, and many regulations are key examples. Pure time series or before-after analysis of the impacts of changes in these policies on the economy of a country will be contaminated by other changes going on in the economy. Simply trying to difference out global trends will not account for systematic differences in the growth path of the country where the reform took place from the average global growth path. This makes evaluation of the impacts of such policies difficult.
So I come back from vacation to find out that I was part of a randomized experiment in my absence. No, this had nothing to do with the wonders of airline travel in Europe (which don’t add that frisson of excitement through random cancellations like their American brethren), but rather two of our co-bloggers trying to figure out if the blog actually makes people recognize me and Jed more (here are links to parts
