Incentives to Cooperate in Network Formation

Lugo, Haydée - Society for Computational Economics - SCE - 2005

We propose a mechanism based on taxes and subsidies that enhances high cooperation in evolutionary networks. The interactions among agents are based on a Prisoners' Dilemma game in which each agent plays the same strategy with its local neighbors, collects an aggregate payoff and imitates the...

Co-evolution of bounded rational agents in adaptive social networks

Lugo, H.; Dalmagro; F. Jiménez J. - Society for Computational Economics - SCE - 2005

Models based on agents has been widely used to study the paradigmatic emergence of cooperation in social systems. In the Spatial Prisoners' Dilemma game introduced by Martin Nowak and Robert May, the agents are greedy and imitate indiscriminately the action of the wealthiest neighbor. Other...

Should the Private Sector Provide Public Capital?

Chatterjee, Santanu - Society for Computational Economics - SCE - 2006

The choice between private and government provision of a productive public good like infrastructure (public capital) is examined in the context of an endogenously growing open economy. The accumulation of public capital need not require government provision, in contrast to the standard...

Quasi Monte Carlo methods for macroeconometric simulation

Li, Jenny X.; Winker, Peter - Society for Computational Economics - SCE - 2001

We continue our research into the Quasi Monte Carlo simulation method and its application in macroeconometrics. Prior research indicated Quasi Monte Carlo simulation to be superior to traditional Monte Carlo methods. Now we address additional important issues including the robustness of the...

Simulated Specification Tests for Panel Multinomial Probit Models: Some Finite Sample Evidence

Wang, Jiahui - Society for Computational Economics - SCE - 2001

. In this paper we propose some simulated Wald and LM tests for testing panel MNP model specification. Unlike LR (or …, but not both. Thus Wald and LM tests are less computationally demanding for simulation-based estimation of panel MNP … specifications, and the test statistics are free of simulation noise. We will focus on four different aspects of a panel MNP model …

Volatility and realized quadratic variation of differenced returns

Hoeg, Esben - Society for Computational Economics - SCE - 2005

This paper analyzes some asymptotic results for a new estimator of integrated volatility in a continuous-time diffusion process of high frequency data (used in asset pricing finance). The estimator, which is computationally efficient, is based on the quadratic variation of the second order...

Testing for Asymmetric Dynamic Oligopoly Models

Siebert, Ralph; Zulehner, Christine - Society for Computational Economics - SCE - 2001

In this paper, we specify a theoretical dynamic oligopoly model with regard to asymmetric firms. We then estimate a structural dynamic model of demand and pricing relations for the semiconductor industry. Using quarterly firm-level output and cost data as well as industry prices from 1974 to...

The Network-Enabled Optimization System (NEOS) - a means of solving optimization problems over the Internet.

Jerrell, Max E.; Campione, Wendy A. - Society for Computational Economics - SCE - 2001

Many optimization methods are available at the present time. The software that implements a particular method may not be available to all users or the software may require a compiler not readily available to all users. The software may require extensive modifications before it can run on a...
