A nonsmooth Newton method with path search and its use in solving $C^{1,1}$ programs and semi-infinite problems
In [S. Bütikofer, Math. Methods Oper. Res., 68 (2008), pp. 235–256] a nonsmooth Newton method globalized with the aid of a path search was developed in an abstract framework. We refine the convergence analysis given there and adapt this algorithm to certain finite dimensional optimization problems with $C^{1,1}$ data. Such problems arise, for example, in semi-infinite programming...

The Impact of Consumer Replacement Decisions and Leapfrogging Behavior on the Timing of New Product Introductions
Firms managing products across multiple generations face the challenge of timing the introduction of new product generations. Early introductions capitalize on the current willingness-to-pay of existing customers, but may also lead to a phenomenon called leapfrogging, i.e. customers skipping a generation. In addition, early introductions cannibalize the existing product in the market...

Price Discounts versus Unit Premiums: Differences in Evaluation Considering Consumers’ Intertemporal Choice
Price discounts or unit premiums? Two alternative approaches to offer and design subscription tarifs. A firm can offer subscriptions of different durations with specific price discounts, the longer a customer subscribes, the lower the price per time unit. Alternatively, a firm can design and differentiate subscriptions of different periods applying the same price per time unit and...

The Impact of Customer-Based Brand Equity on Customer Acquisition and Customer Retention
The topic of marketing accountability is of great interest to marketing researchers and professionals. In this paper, we model the impact of customer-based brand equity on customer acquisition and customer retention which can be used as the basis for calculating customer equity. Using actual purchase data of 39 automobile brands sold in the US between 1999 and 2008 we derive customer...

Customer Lifetime Value Estimation in a Multi-Product Environment
Models about customer lifetime value (CLV) explicitly or implicitly assume a “one-firm oneproduct” environment. We show empirically what problems occur when CLV models are used within a multi-product company. In 99.9% of the cases the summation of the product specific CLVs do not equal the directly estimated CLVs on product portfolio level. When CLVs are used to differentiate between...

However, little research has compared multiple social networks and investigated the link between measures of network structure to commercial success. We make use of network information of online multimedia network platforms and analyze the network strategies of music artists for promoting music. Our...

Bestraft der Arbeitsmarkt eine militärische Weiterausbildung?
Miliz heisst freiwilliges Engagement. Verschiedene Beobachtungen deuten darauf hin, dass dieses zunehmend unter Druck kommt. Erodiert die Freiwilligkeit, oder ist es der Arbeitsmarkt, der solche Engagements nicht mehr zulässt?
Vergleicht man die Einkommensverläufe von jüngeren Milizkadern der Armee mit Nichtkadern, so zeigt sich, dass sich eine militärische Weiterausbildung auf...

The intensity of incentives in firms and markets: Moral hazard with envious agents
While most market transactions are subject to strong incentives, transactions within firms are often not explicitly incentivized. This paper offers an explanation for this observation based on the assumption that agents are envious and suffer utility losses if others receive higher wages. We analyze the impact of envy on optimal incentive contracts in a general moral hazard model and...

Best-response dynamics in a birth-death model of evolution in games
We consider a model of evolution with mutations as in Kandori et al (1993) [Kandori,M., Mailath, G.J., Rob, R., 1993. Learning, mutation, and long run equilibria in
games. Econometrica 61, 29-56], where agents follow best-response decision rules as in Sandholm (1998) [Sandholm, W., 1998. Simple and clever decision rules for a model of evolution. Economics Letters 61, 165-170]....

Equal sharing rules in partnerships
Partnerships are the prevalent organizational form in many industries. Profits are most frequently shared equally among the partners. The purpose of our paper is to provide a rationale for equal sharing rules. We show that with inequity averse partners the equal sharing rule is the unique sharing rule that maximizes the partners' incentives to exert effort. We further show that...
