For 1990-2019, this study presents two-step GMM estimates of EU members' demands for defense spending based on alternative spatial-weight matrices. In particular, EU spatial connectivity is tied to EU membership status, members' contiguity, contiguity and power projection, inverse distance, and...

Seit Langem wird über mögliche Verbindungen zwischen Klima und gewalttätigen Konflikten gestritten. Untersuchungen nähern sich zunehmend einander an, was die Identifizierung von Temperaturschocks als einen entscheidenden, die Gewalt befördernden Faktor betrifft, jedoch ist es weiterhin eine...

We analyze the effect of income inequality on terrorism for a sample of 113 countries between 1984 and 2012. We provide evidence, robust to various methodological changes (e.g., the use of instrumental-variable approaches), that higher levels of income inequality are associated with more...

In this note we study the distortions in an endogenous growth model developed by Grimaud and Tournemaine (2007), where new pieces of knowledge are produced in a R&D sector and used to reduce pollution emissions. Using this model along with a realistic calibration, we conclude that the economy...

The relationship between climatic shocks, natural disasters, and migration has received increasing attention in recent years and is quite controversial. One view suggests that climate change and its associated natural disasters increase migration. An alternative view suggests that climate change...

In this paper I present a new approach to rural-to-urban migration in developing countries. This approach sheds new light on the role of urban-to-rural remittances in bringing about technological change in the agricultural sector of these countries. At the core of the new approach is a utility...

This paper analyse the way how the sustainable developments components are interacting between them and reflects on a possible trade-off between social, human, economic, technological and environmental progress. In this context, I have computed the Pearson correlation coefficient between the...

Costly delay in negotiations can induce the negotiating parties to be more forthcoming with their information and improve the quality of the collective decision. Imposing a deadline may result in stalling, in which players at some point stop making concessions but switch back to conceding at the...

In the present work, agreement on allocation of payments from multiple issues requires unanimous consent of all parties involved. The agents are assumed to know the aggregate payoffs but do not know their decomposition by issues. This framework applies to many real-world problems, such as the...
