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...

Four different programming models dealing with the agricultural sectors in Canada, The Netherlands, Sweden and Denmark are analysed. The purpose is to construct a knowledge base for the development of a new sector model for Danish agriculture. This analysis has created a valuable set of...

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...

This paper analyses how systematic stabilisation policy by monetary authorities may change individual price adjustment decision. The model is a stochastic dynamic menu cost model that results in (S,s)-price rules where the price is fixed inside a band. The resulting price rigidity causes output...

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...

CRAM is an aggregate holding based sector model of Danish agriculture. The model is developed at Unit of Economics (now dissolved) at KVL. The purpose of CRAM is to analyse how Danish agriculture reacts to various socio-political measures. CRAM describes Danish agriculture for every year over a...

In a recent paper Rasmussen (Rasmussen 2003) derived criteria for optimal production under uncertainty based on the state-contingent approach developed by Chambers and Quiggin (2000). While the criteria in the 2003-paper were derived for the one variable input case, and for different types of...
