A semiparametric maximum likelihood estimator

Article Abstract:

A model estimator, which extends the maximum likelihood (ML) model by Robinson and Ichimura and Lee, consistently estimates semiparametric estimator models. This extended model attains semiparametric efficiency bound for models with sets of conditional densities that satisfy an index restriction in the presence of some variable transformation. The model uses the kernel method, which assumes the true conditional density to satisfy the index restriction, and sample averages of probabilities to attain consistency.

Subject evaluation in social experiments

Article Abstract:

There is a significant disagreement between subjects' and investigators' preferences in social experiments. Subjects evaluate experiments based on self-interest motives while investigators rely on altruism. In experimental or clinical cases of health care evaluation, the main concern is on the welfare of the subjects. This motivation induces subjects to consider aspects of treatments and the benefits of the health care program on them.

Information acquisition in auctions

Article Abstract:

This paper studies the incentives of information acquisition in the auction setting. The concept of risk-sensitivity is introduced, and it is demonstrated how this variable directly influences informational-value.
