In this paper we propose to estimate the value distribution of independently and identically repeated first-price auctions directly via a semi-nonparametric integrated simulated moments sieve approach. Given a candidate value distribution function in a sieve space, we simulate bids according to...

In this article, the effect of public expenditure on consumers' welfare is considered by estimating the substitutability of public expenditure for private consumption in the context of Aschauer (1985). Aschauer's full information maximum likelihood estimation requires much more assumptions than...

This chapter provides a selective review on feature screening methods for ultra-high dimensional data. The main idea of feature screening is reducing the ultra-high dimensionality of the feature space to a moderate size in a fast and efficient way and meanwhile retaining all the important...
