What is the impact of campaign spending on votes? Does it vary across election types, political parties or electoral settings?

News production requires investment, and competitors’ ability to appropriate a story may reduce a media’s incentives to provide original content.

This paper investigates the long-term impact of historical missionary activity on HIV in sub-Saharan Africa. On the one hand, missionaries were the first to invest in modern medicine in the region. On the other hand, Christianity influenced sexual beliefs and behaviors that affect the risk of contagion. We build a new geocoded dataset locating Prot...

In this work, we evaluate the performance of recent text embeddings for the automatic detection of events in a stream of tweets. We model this task as a dynamic clustering problem.Our experiments are conducted on a publicly available corpus of tweets in English and on a similar dataset in French annotated by our team. We show that recent techniques...

This paper investigates the impact of increased media competition on the quantity and quality of news provided and, ultimately, on political participation. I build a new county-level panel dataset of local newspaper presence, newspapers' number of journalists, costs and revenues and political turnout in France, from 1944 to 2014. I estimate the eff...

This article examines the impact of trade liberalization on government revenues. Using a new dataset on tax revenues for 130 countries between 1792 and 2006, we identify ninety-nine episodes of trade liberalization defined as a large fall in trade tax revenues not accompanied by a decrease in trade. Seven took place before World War One, seven in t...

This article investigates the long-term consequences of the printing press in the nineteenth century sub-Saharan Africa on social capital nowadays. Protestant missionaries were the first to import the printing press and to allow the indigenous population to use it. We build a new geocoded dataset locating Protestant missions in 1903. This dataset i...

We build an endogenous growth model to analyze the relationships between taxation, corruption, and economic growth. Entrepreneurs lie at the center of the model and face disincentive effects from taxation but acquire positive benefits from public infrastructure. Political corruption governs the efficiency with which tax revenues are translated into...

This article questions the relevance of the different measures of policy performance that are currently used by international organizations to allocate Official Development Assistance (ODA). It evaluates more especially the pertinence of the World Bank’s Country Policy and Institutional Assessment (CPIA) and of the various alternatives that have be...

This paper studies the effect of firm and country reputation on exports when buyers cannot observe quality prior to purchase. Firm-level demand is determined by expected quality, which is driven by the dynamics of consumer learning through experience and the country of origin's reputation for quality. We show that asymmetric information can result...

This paper puts the recent evolution of tax revenues in developing countries in historical perspective. Using a novel dataset on total and trade tax revenues we compare the fiscal cost of trade liberalization in developing countries and in today's rich countries at earlier stages of development. We find that trade liberalization episodes led to lar...

Information is costly to produce but cheap to reproduce. Who are the main providers of original news in the online world, and are they rewarded for this? What are the benefits of breaking out a story, and how does information propagate? This paper addresses these issues by exploiting a unique dataset including all online content produced by general...

The focus of this chapter is on the economics of sub-Saharan African media. Using the history of sub-Saharan African newspapers as well as historical evidence from Europe and the United States, I study the emergence of market-oriented journalism and of an independent and informative press in sub-Saharan Africa. I document the extent to which sub-Sa...

In sub-Saharan Africa, Protestant missionaries were the first both to import the printing press tech...

Trade taxes are an important source of revenue for developing countries. These revenues have fallen over the past decades as these countries liberalized trade. Many developing countries simultaneously experienced a decrease in their total tax revenues, suggesting trade liberalization may have come at a fiscal cost. Using a novel panel dataset of ta...
