Tingley, D., & Wang, S. (2010). Belief Updating in Sequential Games of Two-Sided Incomplete Information: An Experimental Study of a Crisis Bargaining Model. Quarterly Journal of Political Science , 5 (3), 243-255.Abstract
We investigate theoretically and experimentally the "crisis bargaining model", a dynamic game of two-sided incomplete information with player types drawn from a commonly known distribution. Within the experiment we elicited beliefs from players about their opponent's type using a quadratic scoring rule. We implement two treatments that vary a fixed terminal node payoff in the game, generating sharp comparative static predictions in both beliefs and strategies. We examine the relationship between beliefs and actions, which is not well understood in the empirical literature. We find that most beliefs and strategies are responsive to our treatments in the way predicted by theory, and that beliefs track departures from theoretical predictions about strategy choice. We highlight evidence for two deviations from Bayesian beliefs: conservative updating and motivated beliefs. We also consider other important roles for beliefs in strategic choice including the extent of rational expectations and best response to beliefs.

Imai, K., Keele, L., & Tingley, D. (2010). A General Approach to Causal Mediation Analysis. Psychological Methods , 15 (4), 309-334.Abstract
Traditionally in the social sciences, causal mediation analysis has been formulated, understood, and implemented within the framework of linear structural equation models. We argue and demonstrate that this is problematic for three reasons; the lack of a general definition of causal mediation effects independent of a particular statistical model, the inability to specify the key identification assumption, and the difficulty of extending the framework to nonlinear models. In this paper, we propose an alternative approach that overcomes these limitations. Our approach is general because it offers the definition, identification, estimation, and sensitivity analysis of causal mediation effects without reference to any specific statistical model. Further, our approach explicitly links these four elements closely together within a single framework. As a result, the proposed framework can accommodate linear and nonlinear relationships, parametric and nonparametric models, continuous and discrete mediators, and various types of outcome variables. The general definition and identification result also allow us to develop sensitivity analysis in the context of commonly used models, which enables applied researchers to formally assess the robustness of their empirical conclusions to violations of the key assumption. We illustrate our approach by applying it to the Job Search Intervention Study (JOBS II). We also offer easy-to-use software that implements all of our proposed methods.
