In evolutionary games the fitness of individuals is not constant but depends on the relative abundance of the various strategies in the population. Here we study general games among n strategies in populations of large but finite size. We explore stochastic evolutionary dynamics under weak selection, but for any mutation rate. We analyze the frequency dependent Moran process in well-mixed popul...

This paper describes LaoGEM (Lao General Equilibrium Model), a 20 sector, 400 household general equilibrium model of the Lao economy, constructed specifically for the analysis of the effect of road improvement on rural poverty incidence in Laos. Unless otherwise stated, the database of the model refers to the year 2002. These features are relatively standard for comparative static general equil...

The ability to recognize a shape is linked to figure-ground (FG) organization. Cell preferences appear to be correlated across contrast-polarity reversals and mirror reversals of polygon displays, but not so much across FG reversals. Here we present a network structure which explains both shape-coding by simulated IT cells and suppression of responses to FG reversed stimuli. In our model FG seg...

Environmental law plays a key role in shaping policy for sustainability of social-ecological systems. In particular, the types of legal instruments, institutions, and the response of law to the inherent variability in social-ecological systems are critical. Sustainability likely must occur via the institutions we have in place, combined with alterations in policy and regulation within the conte...

This paper examines voting equilibria in a citizen-candidate model with multiple constituencies. Voters in the constituencies elect representatives into a legislative assembly to make a policy choice. Representatives both make policy proposals and vote on each others’ proposals. The model thus formalizes the distinction between advocated policy and enacted policy in representation problems. Und...

The authors' personal-relational equilibrium model suggests that people come to seek equilibrium in their dedication to personal and relational concerns in that these 2 important needs cannot always be gratified simultaneously. The authors proposed that the experience of personal-relational disequilibrium motivates attempts to restore equilibrium and that achieving equilibrium promotes life sat...

We propose a theory of party competition (two parties, single-issue) where citizens acquire party membership by contributing money to a party, and where a member’s influence on the policy taken by her party is proportional to her campaign contribution. The polity consists of informed and uninformed voters: only informed voters join parties, and the party campaign chest, the sum of its received ...

We scrutinize the uniqueness issue of the equilibrium behavior of strategic customers making inter-temporal purchase decisions. We present that multiple equilibria can exist even in the simple setting where two identical customers compete for one unit of item. We prove the existence of a unique equilibrium when their valuations follow uniform distribution.

In this note we prove an existence theorem regarding friendly equilibrium points in extensive games with complete information. The friendly equilibrium points is a refinement of equilibrium points. *) Director del Instituto de Matemática Aplicada. Universidad Nacional de San Luis, CONICET, Ejército de los Andes 950.
