A game-theoretic model of coalition formation among primates

This paper models the coalition formation process among primates as a sequential game. The population consists of individuals having distinct social ranks which is determined by the individual’s resource holding potential. Each member of the population is interested in gaining access to a food resource, either individually or via a coalition. At any given stage of the game, a player can either propose a specific coalition or he can be proposed to in order to join one. Hence, the strategy of a player consists of a sequence of decisions regarding who to propose to for the formation of a coalition and which proposals to accept or reject. We derive the preferences of the players over the various coalition structures under the assumption that the probability of a coalition to obtain the resource is given by a logistic distribution as a function of relative strengths of the players. We show that, given the primates’ strategic behavior, a variety of different coalition structures can emerge in equilibrium.      

Price structure as a marketing variable: An experimental investigation

This study examines the relative impact on preferences of price level and price-structure variables. A pair of four-factor experimental designs were developed to investigate the preferences of students for automobile price structures and recent homebuyers for various price arrangements in buying a house. The findings indicate that, for a majority of the subjects, the structural variables of down payment, interest rate, and monthly payment are more important than price level in determining overall preferences.     

Medium term economic dynamics of the Euro Area

This paper analysis the Euro area’s growth over the last 15–20 years and provides a medium term outlook. We find that in a no policy change scenario, growth will be subdued, essentially reflecting the influence of weak pre-crisis trends, most notably for TFP (especially since the mid-1990’s). This trend will be exacerbated over the coming decade by the ongoing negative fallout from the financial crisis and by the emerging drag on growth emanating from ageing populations. Unlike in standard recessions, the GDP losses relative to a pre-crisis projection appear to be permanent. The picture presented could potentially improve with the implementation of an ambitious programme of structural reforms focussed on boosting employment and productivity. Since the usefulness of such policies is controversial in the current juncture with constrained monetary policy, the paper also looks at the impact of such reforms in a realistically calibrated model and concludes that fears of large permanent deflationary effects from structural reforms are exaggerated.
