In this paper, we study the crime reducing potential of education, presenting causal statistical estimates based upon a law that changed the compulsory school leaving age in England and Wales. We frame the analysis in a regression-discontinuity setting and uncover significant decreases in...

Using a Threshold Vector Autoregression framework identified via sign restrictions, we answer three questions: First, are fiscal policy shocks regime-dependent? Second, which variables are governing the regime? Third, what are the effects of fiscal policies on the main macroeconomic variables in...

We prove that every multi-player Borel game with bounded and lower-semi-continuous payoffs admits a subgame-perfect epsilon-equilibrium in pure strategies. This result complements Example 3 in Solan and Vieille (2003), which shows that a subgame-perfect epsilon-equilibrium in pure strategies...

This paper investigates the effectiveness of an employment program exclusively run by and in a private sector firm, in order to find out whether a private program without cream-skimming can be beneficial to (a) the individual private firm and (b) society at large by outperforming public...

We study a spatial model of party formation in which the set of agendas is the unit circle. We characterize the sets of pure-strategy Nash equilibria under the plurality and proportional rules. In both rules, multiple configurations of parties are possible in Nash equilibrium. We refine our...

This paper introduces a new generation of Early Warning Systems (EWS) which takes into account dynamics within a system composed by binary variables. We elaborate on Kauppi and Saikonnen (2008), which allows to consider several dynamic specifications and to use an exact maximum likelihood...

In this paper we formalize the notion of lexicographic belief hierarchies in standard partitional models (Aumann, 1976). We introduce the notion of epistemic equivalence between two belief space, and show that the state space representation of lexicographic belief hierarchies is equivalent to...

In this paper we consider an ILP-based approach to tackle the problem of determining a treewidth of the graph. We give an overview of existing attempts and develop further LP-based techniques for the problem. We present two different ILP formulations for the treewidth. To obtain the first one we...

We investigate the relations between different types of perfect equilibrium, introduced by Simon and Stinchcombe (1995) for games with compact action spaces and continuous payoffs. Simon and Stinchcombe distinguish two approaches to perfect equilibrium in this context, the classical "trembling...

This paper addresses two-dimensional trajectory optimization problems, where the mover''s speed monotonically decreases/increases in one of the space''s coordinates. For instance, it is well-known that the absolute value of the helicopter speed decreases in altitude because air pressure drops....
