In this paper, we propose second-order sufficient optimality conditions for a very general nonconvex constrained optimization problem, which covers many prominent mathematical programs. Unlike the …
This paper studies the effect of trust on the perceived credibility of earnings news. Using earnings response coefficients, we find that firms located in low-trust regions of the United States expe…
An extensive literature studies the benefits for a firm to be the first to invest in innovative technologies such as information technologies (ITs). However, IT investment often faces the risk of i…
Policy learning using historical observational data are an important problem that has widespread applications. Examples include selecting offers, prices, or advertisements for consumers; choosing b…
Many panel data have the latent subgroup effect on individuals, and it is important to correctly identify these groups since the efficiency of resulting estimators can be improved significantly by …
In recent years, Beijing has implemented urban renewal policies aimed at forcing out rural migrants to restrict the city’s population. One such policy restricts their access to public schools. We…
We propose new sequential simulation–optimization algorithms for general convex optimization via simulation problems with high-dimensional discrete decision space. The performance of each choice …
Platelets are critical blood products. The management of platelet inventory is particularly challenging because of its perishable nature with a short shelf life. Motivated by a platelet inventory m…
We demonstrate a short-time long distance distributed high-temperature sensing by non-local Haar transform (NLH) in optical frequency domain reflectometry (OFDR). By searching similar pixels across…
