We propose a flexible stochastic framework for modeling the market share dynamics over time in a multiple markets setting, where firms interact within and between markets. Firms undergo stochastic idiosyncratic shocks, which contract their shares, and compete to consolidate their position by...

We develop a theory of endogenous regimes transitions (with a focus on democratic consolidation), which emphasizes the role of political culture and of its interaction with political institutions. Political culture re?flects the extent of individual commitment across citizens to defend democracy...

The study of properties of mean functionals of random probability measures is an important area of research in the theory of Bayesian nonparametric statistics. Many results are known by now for random Dirichlet means but little is known, especially in terms of posterior distributions, for...

An important issue in survival analysis is the investigation and the modeling of hazard rates. Within a Bayesian nonparametric framework, a natural and popular approach is to model hazard rates as kernel mixtures with respect to a completely random measure. In this paper we provide a...

The present paper provides a review of the results concerning distributional properties of means of random probability measures. Our interest in this topic has originated from inferential problems in Bayesian Nonparametrics. Nonetheless, it is worth noting that these random quantities play an...

We investigate how nondemocratic regimes use the military and how this can lead to the emergence of military dictatorships. Nondemocratic regimes need the use of force in order to remain in power, but this creates a political moral hazard problem; a strong military may not simply work as an...

Inefficiencies in the bureaucratic organization of the state are often viewed as important factors in retarding economic development. Why certain societies choose or end up with such inefficient organizations has received very little attention, however. In this paper, we present a simple theory...

This paper develops a model to analyze economic performance under different political regimes. An oligarchic society, where political power is in the hands of major producers, protects their property rights, but also tends to erect significant entry barriers against new entrepreneurs. Democracy,...
