Produktbegleitende Dienstleistungen bieten produzierenden Unternehmen die Möglichkeit sich von ihren Wettbewerbern, die zumeist ein ähnliches Produktprogramm aufweisen, zu differenzieren. Empirische Erhebungen belegen, dass Unternehmen im Maschinen- und Anlagebau sowie der Elektroindustrie,...

[...]The analysis of competitive markets culminated in the fundamental theorems of welfare economics which elucidated the (restrictive) conditions under which resource allocation by markets would achieve Pareto efficiency. The first fundamental theorem says that all perfectly competitive...

Two rationality arguments are used to justify the link between condi-tional and unconditional preferences in decision theory: dynamic consistencyand consequentialism. Dynamic consistency requires that ex ante contingentchoices are respected by updated preferences. Consequentialism states...

Richer and healthier agents tend to hold riskier portfolios and spend proportionallyless on health expenditures. Potential explanations include health and wealth eects onpreferences, expected longevity or disposable total wealth. Using HRS data, we perform astructural estimation of a dynamic...

The evidence strongly suggests a robust negative relationship between income and fertility, anda positive relationship between income and longevity. This is puzzling for standard dynamicmodels. For instance, altruistic models that use the most standard preferences in macro-timeseparable CRRA...

A theoretical model is advanced that demonstrates that, if teacher and student attendancegenerate a shared good, then teacher and student attendance will be mutually reinforcing.Using data from the Northwest Frontier Province of Pakistan, empirical evidence supportingthat proposition is...

The paper explores utility measures by combining experiments with mathematical derivations in the psychophysics paradigm. The analysis on the ultimatum game experiment reveals evidences for the utility threshold and thus supports Bernoulli's utility logarithmic law. Both experimental results and...

This paper investigates whether preference interactions can explain why risk preferences change over time and across contexts. We conduct an experiment in which subjects accept or reject gambles involving real money gains and losses. We introduce within-subject variation by alternating...

The concept of ecosystems services has become an important model for linking the functioning of ecosystems to human welfare benefits. Understanding this link is critical in decision-making contexts. While there have been several attempts to come up with a classification scheme for ecosystem...

We investigate the relationship between certain subsets of the core for TU market games and competitive payoff vectors of certain markets linked to that game. This can be considered as the case in between the two extreme cases of Shapley and Shubik (1975). They remark already that their result...
