We reassess the well-known "narrow-but-deep" versus "broad-but-shallow" trade-off in international environmental agreements (IEAs), taking into account the principal-agent relationship induced by the hierarchical structure of international policy. To this end, we expand the modest coalition...

This article describes the development of international trade blocs world wide from the 1950s till 2010. We updated the data on international trade flows and introduced a new trade bloc variable based on the intramax hierarchical clustering technique, which defines trade blocs on actual trade...

This paper sets up a model of trade, in which two countries with differing levels of technology specialize on the production of subsets of the global value chain. In the open economy equilibrium, the technologically backward country exports intermediates in exchange for imports of a homogeneous...

After more than one decade of sustained economic growth, accompanied by falling poverty and inequality, Brazil has been hit by an economic recession starting in 2014. This paper investigates the consequences of this labor market shock for the victory of far-right Jair Bolsonaro in the 2018...

What factors lead underrepresented groups to gain more political representation? I digitize a novel source of data that contains records of Hispanics elected to public office from the local to the federal level from 1984 to 1994 and exploit variation in legal status arising from the 1986...

Our research advances the hypothesis and empirically establishes that a higher incidence of solar eclipses is associated with higher social complexity and complex thinking in premodern societies. We construct a novel dataset of solar eclipses' incidence at the ethnic-group level, bringing...

Drawing on panel data from six elections between 1998 and 2017 in Germany, we estimate the causal effect of immigration – described by Germany’s interior minister as the "mother of all political problems" – on electoral support for the far right and the far left. Our identification...

The role of electoral incentives vs. selection is ideally analyzed in a setting where the same legislators are selected to decide on policies under different electoral rules and where voter preferences on policies can be precisely measured. This is the first paper to look at such a situation....

Cluster policy is recognized as one of the pivotal elements of state-of-art innovation policy. State support for clusters helps to take into account regional peculiarities and engage the most innovative local actors into the process of innovation policy drafting and implementation. Cluster...

How does competition affect the entry and selection of politicians? I use data on U.S. Congressional primary and general elections for the years 1998-2014 to study this question. I measure quality using previous legislative experience and the novel "identity match" quantifying how well...
