Consistent covariance matrix estimation with spatially dependent panel data
Article Abstract:
A simplified version of the standard nonparametric time series covariance matrix estimator was proposed to account for the cross-sectional or spatial dependence in panel data sets. The conditions under which a simple extension of common nonparametric covariance matrix estimation methods produces standard error estimates that are robust to very general forms of temporal and spatial dependence as the time dimension increases were presented. The relevance of the approach was illustrated using Monte Carlo simulations and several numerical examples.

Duopoly behavior in asymmetric markets: an experimental evaluation
Article Abstract:
A study was conducted to analyze duopolies. The study questions the collusion property difference between asymmetric and symmetric markets and the possible effect of asymmetric markets on equilibrium. Subject pair combinations were examined in a repeated game conditioned by output choices. Results show that asymmetric markets generate less cooperation and lag behind symmetric markets in reaching equilibrium.
