The paper investigates determinants of investments in state capacity and institutional change in contemporary Ukraine. After formulating a simple sequential two-stage model of investments in state capacity, the paper estimates autoregressive distributed lag and vector autoregressive models to...

While the Russian invasion of Ukraine has created a new momentum for EU defence integration, the political feasibility of such integration remains disputed, as it may entail both additional financial costs and a loss of sovereignty. Furthermore, design of defence integration is inherently...

This paper analyses the statistical distribution of war size. We find strong support for a Pareto-type distribution (power law) using data from different sources (COW and UCDP) and periods. A power law describesaccurately the size distribution of all wars, but also the distribution of the sample...

We investigate the role of networks of military alliances in preventing or encouraging wars between groups of countries. A country is vulnerable to attack if there is some fully-allied group of countries that can defeat that country and its (remaining) allies based on a function of their...

We report robust evidence of adverse cross-border externalities from terrorism on trade for over 160 countries from 1976 to 2014. Terrorism in one country spills over to reduce trade in neighboring nations. These externalities arise from higher trade costs due to trade delays and macroeconomic...

This paper aims to explain the rise and fall of communism by exploring the interplay between economic incentives and social preferences in different economic systems. We introduce inequality-averse and inefficiency-averse agents responding to economic incentives and transmitting their ideology...

We develop a continuous time dynamic game to provide with a benchmark theory of Arab Spring-type events. We consider a resource-dependent economy with two interacting groups, the elite vs. the citizens, and two political regimes, dictatorship vs. a freer regime. Transition to the freer regime...

Natural resources are generally associated to negative effects on the political environment of a country. This paper explores the impact that oil revenues have on the establishment of a given political system. Based on previous literature, a political economy perspective is employed. A simple...
