Reputation, social identity and social conflict

Smith, John - 2007

matched to play a reduced form bargaining game. We show that this struggle for resources drives a conflict through the … consequences. We show that rational players can contribute to the conflict by aggressively discriminating and that this behavior is … relates to the social conflict literature, which examines the relationship between macro level factors such as unemployment …

Aid and sanctions

Kletzer, Kenneth - 2005

Foreign aid donors and recipient governments often have conflicting objectives. Foreign donors may attempt to influence the policies of recipient governments by offering aid or threatening to suspend aid to sovereign states. This paper considers the credibility of such inducements and the...

Partial identification of discrete counterfactual distributions with sequential update of information

Boes, Stefan - 2009

The credibility of standard instrumental variables assumptions is often under dispute. This paper imposes weak monotonicity in order to gain information on counterfactual outcomes, but avoids independence or exclusion restrictions. The outcome process is assumed to be sequentially ordered,...

Simulating WTP values from random-coefficient models

Rischatsch, Maurus - 2009

Discrete Choice Experiments (DCEs) designed to estimate willingness-to-pay (WTP) values are very popular in health economics. With increased computation power and advanced simulation techniques, random-coefficient models have gained an increasing importance in applied work as they allow for...

Robust estimation of zero-inflated count models

Staub, Kevin E.; Winkelmann, Rainer - 2009

Applications of zero-inflated count data models have proliferated in empirical economic research. There is a downside to this development, as zero-inflated Poisson or zero-inflated Negative Binomial Maximum Likelihood estimators are not robust to misspecification. In contrast, simple Poisson...

Nonparametric analysis of treatment effects in ordered response models

Boes, Stefan - 2007

This paper deals with the identification of treatment effects when the outcome variable is ordered. If outcomes are measured ordinally, previously developed methods to investigate the impact of an endogenous binary regressor on average outcomes cannot be applied as the expectation of an ordered...

Bounds on counterfactual distributions under semi-monotonicity constraints

Boes, Stefan - 2009

This paper explores semi-monotonicity constraints in the distribution of potential outcomes, first, conditional on an instrument, and second, in terms of the response function. The imposed assumptions are strictly weaker than traditional instrumental variables assumptions and can be gainfully...

Count data models with unobserved heterogeneity: An empirical likelihood approach

Boes, Stefan - 2007

As previously argued, the correlation between included and omitted regressors generally causes inconsistency of standard estimators for count data models. Using a specific residual function and suitable instruments, a consistent generalized method of moments estimator can be obtained under...

Simple tests for exogeneity of a binary explanatory variable in count data regression models

Staub, Kevin E. - 2009

This article investigates power and size of some tests for exogeneity of a binary explanatory variable in count models by conducting extensive Monte Carlo simulations. The tests under consideration are Hausman contrast tests as well as univariate Wald tests, including a new test of notably easy...
