Medical decisions involve physicians and patients, entail information asymmetry, and frequently occur in dynamic contexts.We develop a dynamic Bayesian persuasion model of discharge decisions that incorporates these features.This model enables us to identify three sources of moral hazard: patients' financial incentive and physicians' altruistic and financial incentives.We leverage the unique reimbursement structure of a public health insurance in China to structurally estimate the model and quantify the impacts of the three sources on treatment and welfare outcomes.We find significant effects of all three sources of moral hazard, and the effect of each source depends nonlinearly on the other two.In particular, we are the first to quantify the impact of moral hazard driven by physicians' altruism, and find that the impact is amplified by preference inconsistency between physicians and patients in patients' expense-health tradeoff.

How to adequately select like-minded individuals and at the same time make merit-based appointments is the core of the modern civil servant selection system, which is also regarded as the key to balancing political stability and socioeconomic development. Based on a large-scale survey spanning the entire process of a civil servant selection in China, this paper attempts to provide a new perspective for re-examining this selection system. It finds that: first, those who passed have higher motivation for public service than those who failed, recognize the government's functional roles and actions more, and are less willing to take risks, challenge authority, and speak out against social injustice. Second, these differences in attitudes are attributable to the self-selection effect, i.e., individuals with the corresponding traits are more likely to be selected. Part of the difference, moreover, comes from the sting of failure, i.e., the motivation of the "losers" under competitive selection to work for the public good will be dampened and they may question the functions and behavior of the government. The paper argues that the selection may well identify qualified applicants while produce and reinforce the cognitive rift between the government and the public.
