We use a cost of carry model with nonzero transactions costs to motivate estimation of a nonlinear dynamic relationship between the S&P 500 futures and cash indexes. Discontinuous arbitrage suggests that a threshold error correction mechanism may characterize many aspects of the relationship...

In this paper, we use the empirical likelihood method to make inferences for the coefficient difference of a two-sample linear regression model with missing response data. The commonly used empirical likelihood ratio is not concave for this problem, so we append a natural and well-explained...

This paper is concerned with the Online Quota Traveling Salesman Problem. Depending on the symmetry of the metric and the requirement for the salesman to return to the origin, four variants are analyzed. We present optimal deterministic algorithms for each variant defined on a general space, a...

On the basis of stratified sampling, we conduct a survey of 1 313 migrant workers, to analyze various factors influencing migrant workers' consumption level and the difference in consumption structure between two generations of migrant workers, using the multivariate logistic regression and...

This paper presents a newly developed aero-servo-elastic platform for implementing smart rotor control and shows its effectiveness with aerodynamic loads on large-scale offshore wind turbines. The platform was built by improving the FAST/Aerodyn codes with the integration of an external...

type="main" <p>Home equity lending grew rapidly from 2000 to 2008 with balances more than tripling. In this article, we examine the role this phenomenon may have played in increasing aggregate default risk during the mortgage crisis. We also document a relationship between growth in home equity...</p>

Store buildings usually have distinct characteristics of significant depth, high human density and heat-emitting sources, a high simultaneity usage coefficient for the air conditioning system, etc. The aim of this paper is to develop a rational rating method for green stores. By comparing the...

We examine changes in lending behavior in response to the Federal Reserve’s requirement for disclosure of loan pricing information implemented in 2004 for two broad types of lenders, depository and nondepository institutions. We find that although subprime approval rates generally increased...

Among the top 10% most expensive patients, olanzapine and risperidone treatments were associated with comparable cost reductions in inpatient care. The choice of agent was associated with patients’ co-morbid condition and was correlated with cost reduction in inpatient medical/surgical or...
