The Great Observatories Origins Deep Survey (GOODS) is designed to gather the best and deepest multiwavelength data for studying the formation and evolution of galaxies and active galactic nuclei, the distribution of dark and luminous matter at high redshift, the cosmological parameters from distant supernovae, and the extragalactic background light. The program uses the most powerful space– an...

Peer-to-Peer (P2P) networks have emerged as a popular alternative to traditional client-server architectures for the distribution of information goods. While there is a great deal of research on these networks in the computer science literature, until recently there has been little academic research considering the salient economic characteristics of these networks. In this paper, we outline so...

This paper proposes a symmetry-breaking model of trade with a (large but) finite number of (ex-ante) identical countries and a continuum of tradeable goods, which differ in their dependence on local differentiated producer services. Productivity differences across countries arise endogenously through free entry to the local service sector in each country. In any stable equilibrium, the countrie...

This paper extends the club model of religion to better account for observed patterns of extremism. We adapt existing models to a multi-agent framework and analyze the distribution of agents and clubs. We find that extremism is more successful when religious groups are able to produce close substitutes for standard goods and that increased access to publicly provided goods can reduce the extrem...

How do presidents win legislative support under conditions of extreme multipartism? Comparative presidential research has offered two parallel answers, one relying on distributive politics and the other claiming that legislative success is a function of coalition formation. The authors merge these insights in an integrated approach to executive-legislative relations while also considering dynam...

If property rights to consumption goods are insecure, the incentives to trade in a barter economy are reshaped. In a pure exchange economy, we examine the case where two contestable consumption goods are vital to two agents and initial endowments follow a binary distribution. In line with the existing literature, we examine in a two–stage game how the equilibrium security of claims to property ...

We study the interaction between product quality, prices and demand in a dynamic model of asymmetric information. Sellers choose between producing high quality goods which gives low profits today but increases probability of future survival in the market and low quality ones which gives higher returns today but lowers future survival. However, demand depends on expected quality. Multiple steady...

The logistics problems in business environments deal with assignation from a number of sources to a number of destinations. Each source offers amounts of goods, while each destination demands quantities of these goods. The object is to find the cheapest transporting schedule that satisfies the demand without violating supply restraints. In this paper we propose to use Fuzzy Sets to represents t...
