This paper introduces bias-corrected estimators for nonlinear panel data models with both time invariant and time …/selection bias. We then estimate the primary equation by fixed effects including an appropriately constructed control function from … both steps might employ nonlinear fixed effects procedures it is necessary to bias adjust the estimates due to the …

We characterize the bias of propensity score based estimators of common average treatment effect parameters in the case …

Turf wars commonly occur in environments where competition undermines collaboration. We develop a game theoretic model … joint production but introduces competition for the reward. We find that collaboration has a non-monotonic relationship with …
