The existing literature on investment and reinsurance is limited to the study of continuous-time problems, while discrete-time problems are always ignored by researchers. In this study, we first discuss a multi-period investment and reinsurance optimization problem under the classical...

This paper analyses the efficiency of English and Welsh Young Offender Institutions (YOIs) during the period 2007-08 to 2010-11 accounting for the fact that prisons can both promote good behaviour but also generate undesirable outcomes. With these problems in mind, a new non-parametric program...

For global warming mitigation by carbon emission reduction through rate-based carbon emission trading scheme (RETS), feasible policies require discreet and accurate understanding to the scheme mechanisms and impacts. This paper develops RETS models that integrate cost-effective decision-making...

In this paper, we discuss the relationship between multi-attribute utility theory and data envelopment analysis (DEA) models without explicit inputs (DEA-WEI), including dual models and some theoretical analysis of DEA-WEI models. We then propose generic DEA-WEI models with quadratic utility...

We present evidence on productivity improvement experienced by the research institutes of the Chinese Academy of Sciences (CAS) after its implementation of the Knowledge Innovation Program (KIP). Using a balanced panel of data on R&D inputs and outputs of 59 research institutes in CAS, we...

Traditional DEA models and nonlinear (diversification) DEA models are often used in performance evaluation of portfolios. However, the diversification models are usually very complicated to compute except the very basic models. And the classic DEA models still need to be further justified and...
