The political and economic impact of country size has been a frequently discussed issue in social science. In accordance with the general hypothesis of Montesquieu, this paper demonstrates that there is a robust negative relationship between the size of country territory and a measure of the...

The article features a temporal approach to modelling the social impact of Western colonialism. We collect a data set for all former colonies and dependencies that are regarded as countries today (143 observations). Our data, as well as existing theory, suggest that the very heterogeneous era of...

At the creation of the European Community in 1957, little attention was paid to environmental concerns. It’s only in 1997, after decades of debate, that the ‘Integration Principle’ became formally engraved in European treaties. This principle, requiring all policies to take environmental...

International investment agreements define commitments on investment protection, but also shed light on how these commitments are to be integrated with other public policy objectives. Investment protection in the context of environmental regulation has been a frequent source of controversy and...

In this paper we examine the claim that natural resources invite civil conflict, and challenge the main stylized facts in this literature. We find that the conventional measure of resource dependence is endogenous with respect to conflict, and that instrumenting for dependence implies that it is...

We use three different measures of fractionalization (with varying potential for members of one fraction to “mendaciously” pass for a member of another) to revisit the correlation between natural resources and the onset of conflict. The combination of ethnic fractionalization and resource...

Since the middle ages, when Europe was still at a Malthusian stage of development, interpersonal violence has been in steady decline, and institutions and norms limiting violence – in particular property rights – have expanded. Here we put forward a Malthusian model of violence where these...

There is controversy about whether geography matters mainly because of its contemporaneous impact on economic outcomes or because of its interaction with historical events. Looking at terrain ruggedness, we are able to estimate the importance of these two channels. Because rugged terrain hinders...

The world is banking on a major increase in food production, if the dietary needs and food preferences of an increasing, and increasingly rich, population are to be met. This requires the further expansion of modern agriculture, but modern agriculture rests on a small number of highly productive...

This paper proposes that ancestral use of irrigation reduces contemporary female labor force participation and female property rights. We test this hypothesis using an exogenous measure of irrigation and data from the Afrobarometer, cross-country data, the European Social Survey, the American...
