Standardized Lm Tests For Spatial Error Dependence In Linear Or Panel Regressions, Badi H. Baltagi, Zhenlin Yang
Standardized Lm Tests For Spatial Error Dependence In Linear Or Panel Regressions, Badi H. Baltagi, Zhenlin Yang
Research Collection School Of Economics
The robustness of the LM tests for spatial error dependence of Burridge (1980) for the linear regression model and Anselin (1988) for the panel regression model are examined. While both tests are asymptotic ally robust against distributional misspecification, their finite sample behavior can be sensitive to the spatial layout. To overcome this shortcoming, standardized LM tests are suggested. Monte Carlo results show that the new tests possess good finite sample properties. An important observation made throughout this study is that the LM tests for spatial dependence need to be both mean- and variance-adjusted for good finite sample performance to be …

How Robust Is Undominated Nash Implementation?, Takashi Kunimoto
Research Collection School Of Economics
Palfrey and Srivastava (1991) show that almost any social choice correspondence(SCC) is implemented in undominated Nash equilibrium, a refinement of Nash equilibrium. By requiring solution concepts to have closed graph in the limit of complete information, Chung and Ely (2003) investigate the robustness of undominated Nash implementation. Their robustness test concludes that when preferences are strict (or more generally, hedonic), only monotonic SCCs can be implemented in the closure of the undominated Nash (equilibrium) correspondence. This paper re-examines this robustness test. I show that almost any SCC is implemented in the closure of the undominated Nash correspondence, provided that the …
