Contextual Dynamic Pricing: Algorithms, Optimality, and Local Differential Privacy Constraints

no code implementations4 Jun 2024 Zifeng Zhao, Feiyu Jiang, Yi Yu

In particular, we propose a stochastic gradient descent based ETC algorithm that achieves an optimal regret upper bound of order $d\sqrt{T}/\epsilon$, up to a logarithmic factor, where $\epsilon>0$ is the privacy parameter.

Estimation for conditional moment models based on martingale difference divergence

no code implementations17 Apr 2024 Kunyang Song, Feiyu Jiang, Ke Zhu

To overcome this identification issue, we further provide a two-step estimation procedure for the model with intercept parameters.

A Consistent ICM-based $χ^2$ Specification Test

no code implementations29 Aug 2022 Feiyu Jiang, Emmanuel Selorm Tsyawo

In spite of the omnibus property of Integrated Conditional Moment (ICM) specification tests, they are not commonly used in empirical practice owing to, e. g., the non-pivotality of the test and the high computational cost of available bootstrap schemes especially in large samples.
