There has been progress in estimating the demand and cost primitives underlying the static profit and consumer surplus functions derived from simple IO models. This delivers profits and consumer surplus as a function of the distribution of the state variables of the agents active in the market,...

A multi-agent model is proposed for the analysis of self- organization of trade networks. The model takes into account time spent on transactions (`` trade distance). It is shown that the same set of traders may generate trade networks of different structures depending on average trade distance....

It is common practice in econometrics to base a model to be applied to data on pure theory, and yet to replace the variables of the pure theory by aggregates of them. But if one must aggregate, there are many alternative ways of doing so; we present an approach using heuristic optimization for...

Anderson and Moore  presents a procedure for solving linear perfect foresight models and Andersonn[Anderson1993] shows how to apply this technique to non linear models. The technique requires eigenvalue computations for a sparse linear system to deal with the long run dynamics and computations...

Adaptation factors are not properly involved yet in decision making and not measured regularly in economic terms. In the paper we mean under adaptation cost an opportunity cost which one has to bear using a certain inefficient adaptation system compare to the better system. Adaptation cost as a...

Maastricht is only one catchword which emphasizes the fast growing importance of interactions between economic areas. On the other hand synergetics is one catchword which represents the progress in the exploration of complex, nonlinear, dynamic systems. Here, we make use of one evolution in...

In auctions of government treasury securities, each bidder is permitted to enter multiple price-quantity bids. Gordy (1996) finds empirical evidence from Portugal's treasury bill auctions that multiple bidding is used more intensively as the potential for winner's curse increases. That is,...

We propose a tractable simplification of Gold's (1965, 1967) inductive inference model based on neural networks. In this way, we can introduce explicitly institutions in a learning model. In particular, the hidden layer of neural network is shown to perform certain functions-data preprocessing...

We analyze cross-sectional patent data using a finite mixed Poisson regression model with covariates in Poisson rates and mixing probabilities. Maximum likelihood estimation based on the EM and quasi-Newton algorithms, a model selection procedure, residual analysis and goodness-of-fit tests are...

Standard System of national accounting (SNA) was desighed and developed for the purpose of mesurement and comparable presentati- on of economic state and activity of different countries and on different levels. It's recognized that despite great importance of the very existance and wordwide...
