Better understanding the state of political systems – particularly in developing countries – via methods used by economists does not appear to be commonplace. However, it is an increasingly popular method that provides results which complement those obtained by political scientists. Benjamin Marx, permanent faculty member, has demonstrated their usefulness in research he has conducted in Kenya and Indonesia.

You study political life in developing countries, but with an economist’s approach. Why this choice? What does economics bring to the analysis of phenomena that are usually tackled by political science?

Benjamin Marx – All the research projects I have conducted with this interdisciplinary approach have convinced me of its added value in the study of political phenomena. Several of my projects are collaborations between economists and political scientists. This is the case of a study I conducted on vote buying in Uganda, and of an article on Islamic law institutions and the 1960 land reform in Indonesia, both of which were conducted with US-based researchers.

In this approach, political science brings its conceptual approach, its knowledge of institutional mechanisms (indispensable for understanding electoral phenomena), and its precise knowledge of local contexts. In my work on Africa I have especially drawn on the work of political scientists such as Joel Barkan and Jeffrey Herbst, who have influenced many scholars in both disciplines.

Meanwhile, economics and econometrics bring their methodological tools as well as great rigor to causal inference, which refers to a researcher’s ability to establish a causal relationship between X and Y variables. This type of approach has recently allowed economists to improve our understanding of political phenomena in developing countries.

For example, two Greek economists – Stelios Michalopoulos and Elias Papaioannou – have established the existence of a structural relationship between pre-colonial political institutions and the different levels of economic development observed in sub-Saharan Africa. Other economist-led research has improved our understanding of phenomena at the crossroads of economics and other social sciences, such as corruption.

There is now a fairly broad consensus among development economists around the importance of institutional phenomena in the emergence of longstanding trends in economic development. My thesis supervisor, Daron Acemoglu, has significantly contributed to this research. To study the political economy of developing countries is to attempt to understand the political and institutional phenomena that hinder the eradication of poverty, the improvement of health and education conditions, good governance, etc. It also sparks imagination about potential solutions.

You recently studied voter turnout in Kenya. How did you proceed and what conclusions did you reach?

B.M. – This was a project conducted in collaboration with the Electoral Commission of Kenya in 2013, aiming to promote citizen participation in a difficult institutional context. The previous presidential election in 2007 had led to an upsurge of interethnic violence in the country, leading Kenya to reform its electoral process and to adopt a new Constitution.

The study focused on the evaluation of simple messages transmitted to citizens by SMS, providing basic but essential information on how the electoral process was functioning in this new framework. For example, some messages contained simple reminders about the practicalities of the voting process, while others sought to succinctly explain the role of a parliamentarian.

Using a randomized evaluation, we were able to show that these messages had increased voter turnout, which is a major challenge in a country where more than 20% of the adult population is illiterate. On the other hand, these messages had another, more unexpected effect: in a survey conducted several months after the election, we observed that citizens who received these messages had a lower level of trust in their electoral institutions.

We explain this result by the fact that the messages increased the salience of the election for voters, while they sent potentially ambiguous signals about the transparency and administrative competence of the Commission. Once confronted with the reality of the election and the difficulties observed on the ground, voters were able to interpret the content of these messages in a different way. Our study therefore highlights the benefits of an information campaign of this type, while showing the importance of the content of the messages: any information about a “sensitive” electoral process can give rise to potentially contradictory interpretations, which will affect citizens’ trust in their democratic institutions in the long term.

You have also studied the relationship of Muslim institutions to society and politics in Indonesia, and have highlighted the importance of land reform in this relationship. How do you explain this?

B.M. – This work was part of a more comprehensive research project on the relations between the Indonesian state and Islamic organizations since 1945. Indonesia has approximately 225 million citizens of Muslim faith, making it the largest Muslim country in the world.

In this case, the purpose of this first study was to study the effects of an agrarian reform that was initiated by the Indonesian government in 1960, and that ended in resounding failure. This work revealed the decisive role of Islamic institutions in the failure of this reform. We showed that an institution of Islamic law called waqf (known in French as biens de mainmorte or habous in North Africa) allowed large landowners to eschew the redistribution of their farmland to the poorest peasants. The waqf is an original legal status based on a donation made in perpetuity for the purpose of financing a work of public or religious utility. For example, a landowner can transfer his land in waqf by stipulating that the land will be used to finance an Islamic school. A property benefiting from waqf status cannot be subject to expropriation and its purpose cannot be changed after the deed of foundation. This institution has historically played an important – and probably negative – role in the economic development of certain regions, particularly in the Ottoman Empire.

Under pressure from Islamic organizations, the Indonesian government of the time had accepted the fact that land with waqf status could not be subject to the redistribution law. This legal element greatly contributed to the failure of land reform. Indeed, landowners massively transferred their land to waqf status to escape redistribution. We were able to show that these transfers led to a strengthening of local Islamic institutions, especially in the educational sphere. A large number of Islamic boarding schools (known in Indonesia as pesantren) are financed by waqfs, and many of these institutions play an important role in local political life. We argue that land transfers to waqf status in the 1960s had a lasting effect on support for political Islam. Today, Islamist parties (which remain a minority nationwide) are doing best electorally in the regions that should have been most affected by land redistribution. These regions are also adopting more local laws based on Islamic law (Sharia). Land reform has thus enduringly shaped the trajectory of political Islam in Indonesia, due to the mediating role played by the waqf.

We are currently working on a second study that focuses more specifically on the role of Islamic schools. This article shows how Islamic schools have adapted to the growth of public education since the 1970s. We also study the ideological consequences of the competition between public and Islamic schools.

You have also studied corruption phenomena related to obtaining housing in slums and the issue of slums in general. What have you learned about this topic?

B.M. -My colleagues and I learned a lot over the course of this project. I’ll give you two examples.

First, the fact that slums in developing countries are not areas of lawlessness, as they are often described. Slums have a complex system of informal regulations and a real housing market. In Kibera, Nairobi’s largest slum and one of the largest slums in Africa, 92% of residents pay a monthly rent. This market is dominated by extremely powerful local political actors who have the power to intercede on behalf of landlords or tenants in conflicts over land use.

Second, our work has shown that the fundamental question raised by slums is the question of social mobility. Is life in the slums a springboard to a better life, integrated into the metropolis, with access to public services and better jobs? Or, conversely, are slums “poverty traps”, with residents remaining prisoners of their precarious living conditions from one generation to the next?

Paradoxically, most economists have a very optimistic view of slums: since living standards are generally much higher in urban areas, many people think that slums are a springboard for rural-urban migrants, who get closer to the opportunities offered by the city. In reality, our level of knowledge about these mechanisms is relatively limited. Few longitudinal studies have been carried out to understand whether there is real mobility from the slums to the middle classes and the formal sector. In our study of Kibera, we show that half of the residents live in the slum for more than eight years, and a large number of families have been there for several generations. This may lead to a less optimistic perspective on the phenomenon. To answer these questions, we will need to continue to follow the families who responded to our survey in 2012-13, in order to better understand whether the social mobility of residents of slums such as Kibera is a myth or a reality.

Can your research findings give rise to exchanges with politicians and/or citizens in the studied fields, particularly to consider solutions?

B.M. – Of course! All this research is meant to help governments, civil society, and citizens to better understand how to improve the governance and transparency of their institutions, how to promote political participation, and so on. Several of the aforementioned studies were carried out in consultation with local actors. For example, the study conducted in Uganda aimed to assess the impact of an information campaign on vote buying conducted by 13 civil society organizations in Uganda. This coalition of NGOs had contacted us in 2015 to create a randomized evaluation of their operations. The study in Kenya was also a collaboration with the government, as I mentioned earlier.

Finally, I have been working for several months on the implementation of a project on decentralization with the government of Indonesia and the World Bank. The purpose of this study is to help 75,000 Indonesian villages better spend the funds they receive from the central government (which have been sharply growing since 2014) by improving governance in the villages. It also aims to train municipalities on issues of public administration and local democracy. This project will allow us to apply what we have learned from other recent studies on decentralization in Indonesia and other emerging countries. These countries are often ahead of us in terms of evaluation policies: in Indonesia, but also in India, South Africa, and Brazil (until recently) there is a real interest in collaborations between governments and researchers to evaluate and better understand the effects of a program or public policy.
