University bookstores have a complex multi-product, multi-supplier supply chain with complex channel relationships such as product substitution, random yields, reverse logistics and returns, and risk sharing contracts. Supply chain efficiency is important to the bookstore due to low overall profit margin. The used book buyback activity is an example of reverse logistics with random yield with s...

Sweden has adopted ambitious energy savings objectives for buildings, but at the current rate of energy efficiency investments the objectives are unlikely to be reached. In this article we report the early findings of how real estate owners reason and act in energy efficiency investment decisions. Based on the results from interviews with the real estate companies, the companies have been divid...

This paper investigates cost and profit efficiency of German hospitals. More specifically, it deals with the question how hospital efficiency varies with ownership, patient structure, and other exogenous factors, which are neither inputs nor outputs of the production process. We conduct a Stochastic Frontier Analysis (SFA) on a multifaceted administrative German dataset combined with the balanc...

This paper analyzes Pareto optimal non-linear taxation of profits and labor income in a private information economy with endogenous firm formation. Individuals differ in both their skill and their cost of setting up a firm, and choose between becoming workers and entrepreneurs. I show that a tax system in which entrepreneurial profits and labor income must be subject to the same non-linear tax ...

This study examines the cost and profit efficiency of banking sectors in twelve transition economies of Central and Eastern Europe (CEE) over the period 1993-2000, using the stochastic frontier approach (SFA) and the distribution free approach (DFA). The managerial inefficiencies in CEE banking markets were found to be significant, with average cost efficiency level for 12 countries of 72 and 7...
