We present explicit convex programs which characterize the equilibrium for certain additively separable utility functions and CES functions. These include some CES utility functions that do not satisfy weak gross substitutability.

This study presents, motivates, and illustrates the use of a computational laboratory for the investigation of evolutionary trade network formation among strategically interacting buyers, sellers, and dealers. The computational laboratory, referred to as the Trade Network Game Laboratory (TNG...

The future of electronic commerce will be shaped by open, heterogeneous and complex structures, consisting of networked marketplaces. Software agents will interact and negotiate on behalf of their human (or organizational) principals. Principals will be able to implement fraudulent strategies in...

This paper aims to understand some of the mechanisms which dominate the phenomenon of knowledge diffusion in the process that is called ‘interactive learning’. We examine how knowledge spreads in a network in which agents interact by word of mouth. We define a social network structured as a...

Joining the European Union club implies, among many other policy changes, full integration of Romania's economy into EU's customs union. This is expected to have significant implications for domestic farmers and food processors. The paper constructs a single-country Applied General Equilibrium...

The aim of this paper is to develop and apply Neural Network (NN) models in order to forecast regional employment patterns in Germany. NNs are statistical tools based on learning algorithms with a distribution over a large amount of quantitative data. NNs are increasingly deployed in the social...

Optimization algorithms must be among the most common numerical methods used by economists. Yet, there is surprisingly little guidance on choosing the appropriate one. This problem is most notable with regard to conventional versus global optimizers. Typically, a global optimizer is used when a...

The accelerated development in Peer-to-Peer (P2P) and Grid computing has positioned them as promising next generation computing platforms. They enable the creation of Virtual Enterprises (VE) for sharing resources distributed across the world. However, resource management, application...

The paper discusses some of the problems of subsistence agriculture in countries in transition and proposes a methodology for analysis. It demonstrates that approaches which ignore the dualistic agriculture structure cannot provide consistent estimates of the behavioural parameters of the total...

This paper was prepared for the conference ``Public Access to the Internet,'' JFK School of Government, May 26--27 , 1993. We describe some of the technology and costs relevant to pricing access to and usage of the Internet, and discuss the components of an efficient pricing structure. We...
