The main objective of this report is to describe a decision-support system for dynamic retail pricing and pro-motion planning. Our weekly demand model incorporates price, reference price effects, seasonality, article availability information, features, and discounts. Building on previous research, we quantify demand interdependencies and integrate the resulting profit-lifting effects...

Applying stochastic frontier analysis, we estimate the importance of sports in society as technical efficiency of countries in the production ofnOlympic success since the 1950s. Our measures of success are medal shares and a broader concept including Olympic diplomas. Following Bernard andnBusse (2004), population and GDP are used as inputs. While the impact of GDP is always positive...

This paper presents a model in which final goods producers outsource intermediate input
production. Intermediate inputs are differentiated and their production can be located at home or abroad. The model is used to examine competitive location policy in a (two-country) free trade area (FTA). It is shown that national public infrastructure investment has a positive effect on...

This paper applies the five standard criteria for assessing the performance of an economy to one of its sectors, namely, the provision of health care. They are (1) matching of consumer preferences, (2) technical efficiency, (3) adaptive capacity, (4) dynamic efficiency, and (5) a distribution of income that provides incentives for producers to attain criteria (1) through (4).

The impact of aging on healthcare expenditure (HCE) has been at the center of a prolonged debate. This paper purports to shed light on several issues. First, it presents new evidence on the relative importance of the two components of HCE that have been distinguished by Zweifel, Felder and Meier (1999), viz. the cost of morbidity and the cost of mortality (their "red herring...

Nordic historians have asserted for a long time that in the Nordic countries only few people, if any, perceived increased threats of war prior to the World War II outbreak. This would explain, and possibly excuse, why their governments did not mobilize their armies until it was too late. This paper questions this established notion by deriving new estimates of widely held war threat...

We develop a product market theory that explains why firms provide their workers with skills that are sufficiently general to be potentially useful for competitors. We consider a model where firms first decide whether to invest in industry-specific human capital, then make wage offers for each others’ trained employees and finally engage in imperfect product market competition....

In the literature on optimal indemnity schedules, indemnities are usually restricted to be non-negative. Keeler [1974] and Gollier [1987] show that this constraint might well bind: insured could get higher expected utility if insurance contracts would allow payments from the insured to the insurer at some losses. This paper extends Collier’s findings by allowing for negative...
