This article discusses models in data envelopment analysis (DEA) relaxing the standard convexity assumptions. The basic model treats mutually incomparable pairs of sets to be generated by a procedure proposed earlier. Each pair consists of a consumption set and a production set of feasible...

We discuss the design of interactive, internet based benchmarking using parametric (statistical) as well as non-parametric (DEA) models. The user receives benchmarks and improvement potentials. The user is also given the possibility to search different efficiency frontiers and hereby to explore...

A major challenge to legislators, insurance providers and municipalities will be how to manage the reimbursement of health-care on partially open markets under increasing fiscal pressure and an aging population. Although efficiency theoretically can be obtained by private solutions using...

Effective economic regulation demands clear objectives, sound economic reasoning and a careful analysis of the inevitable trade-offs between conflicting societal interests. The key problems are linked to the information asymmetry between the regulator and the regulated firms. Although the market...

In this paper, we suggest that inefficiency may be an indirect, on-the-job compensation to agents in an organization. We show how to use actual production data to reveal the trade-offs between different inefficiencies (slacks). Moreover, we discuss how to use this to improve productivity...

Using Data Envelopment Analysis (DEA), we provide a framework to analyze the potential gains from quota trading. We compare the industry profit and structure before and after a free trade reallocation of production quotas. The effects of tradable production quotas depend on several technological...

We discuss how to measure allocative efficiency without presuming technical efficiency. This is relevant when it is easier to introduce reallocations than improvements of technical efficiency. We compare the approach to the traditional one of assuming technical efficiency before measuring...

This paper analyzes the design of the Danish milk quota exchange. We focus on the restriction that each producer can only submit a single bid (a quantity and a price limit). We argue that this restriction creates inefficiencies for two reasons. First, a single bid cannot express a buyer's...

We characterize optimal investment and compensation strategies in a model of an investment opportunity with managerial incentive problems, caused by asymmetric information over investment costs and the manager's desire to consume slack, and flexibility over the timing of its acceptance. The...

The purpose of this paper is to study the effects of introducing information systems into a model featuring managerial incentive problems and investment opportunities that are mutually exclusive over time. In a principal-agent model in which a manager (agent) has superior information about...
