Wie viel Europa braucht die Energiewende?

It is often argued that Germany’s energy transition (the so-called “Energiewende”) needs to be “Europeanized”, so as to make the transition process more efficient. In particular, the German system of feed-in tariffs for renewables is criticized for being an obstacle to efficient European energy supply. However, we point out that Germany’s approach is no outlier but rather well embedded in the European context of heterogeneous energy policies. Also, full centralization and harmonization of political decisions on the EU-level may not be desirable in many fields of energy policy beyond climate protection if the full economic costs of energy supply are taken into account. In addition, legal and politico-economic constraints need to be considered. Against this background, we identify priorities for fostering the European dimension of the Member States’ energy policies, such as the coordination of grid extensions and capacity markets.     

Tenants, Landlords, and Soil Conservation

It has long been argued that tenants tend to overexploit land, but this conventional wisdom has been derived largely without consideration of landlords' actions. We examine what happens when landlords can invest in durable conservation measures in addition to choosing rental contract terms. When tenants are risk neutral, landlords overinvest in conservation under cash rental contracts but can achieve first best levels of output and protection against land degradation when conservation investment is combined with share rental. When tenants are risk averse, the first best is unattainable. In this case, conservation investment combined with share rental results in output levels below the first best, while equilibrium conservation investment may be greater or less than the first best. These results suggest that contract form and conservation investments are likely made simultaneously, so that econometric studies of conservation practice adoption that treat rental status as exogenous are likely subject to bias.     

Productive and harmful entrepreneurship in a knowledge economy

This paper develops an endogenous growth model with productive entrepreneurial activities and rent-seeking. Our purpose is to link contributions to the entrepreneurial and the endogenous growth literature. We deal with complementarity between productive entrepreneurship and harmful rent-seeking activities leading to potentially multiple equilibra in the economy. The degree of rent-seeking is endogenous in our model and is influenced by the economy’s legal and institutional framework as well as capital market imperfections. Policy which establishes the legal environment and financial institutions dealing with capital market imperfections together decides which of the potentially multiple equilibria is chosen by the economy. This institutional choice implies the solution to a trade-off between high economic growth on the one and a high level of productivity on the other hand.     

Firm size,small business presence and sales of innovative products: A micro-econometric analysis

In our generalized TOBIT analysis we identify a number of variables which have an impact on a firm's innovation output. Among others we find that larger firms generally have a higher probability of selling some innovative products, although this probability increases less than proportionately with firm size. Given that a firm has some sales of innovative products, the share of such products in a firm's total sales tends to be higher in smaller firms. Moreover, a strong small business presence in a sector seems to enhance imitative innovation but has no influence on true innovations, whereas market concentration has no influence on innovation output in whatever definition. We also find evidence of regional knowledge spill-overs. Furthermore, our results are consistent with Schmookler's hypothesis that the growth of demand enhances innovation. The outcomes about the impact of R&D collaboration and technology transfer on innovation remain ambiguous.     

Why is Austria’s Pension System So Much Better Than Germany’s?

The pension systems in both Germany and Austria have undergone substantial reforms, though only one of the countries appears to have had success. Average earners in Austria will receive gross pensions equivalent to 78.1% of their average earnings, whereas in Germany they will receive just 37.5%. The authors argue that Germany has been left with a system that has abandoned the goal of protecting people's standard of living.

Do they shop to stand out or fit in? The luxury fashion purchase intentions of young adults

A three‐study examination of young adults suggests that their motivation for status in terms of their luxury fashion purchase intentions is impacted by a bandwagon effect. In Study 1, qualitative research informs what fashion items represent status to young adults, how they view these items, and how they view others owning these items. In Study 2, survey research establishes the link between the motivation for status (status consumption) and purchase intention/ownership of these fashion items. In Study 3, a national survey of young adults examines what mediates and moderates the motivation for status to lead to luxury fashion purchase intentions. Results from the three studies indicate that status consumption has a positive impact on purchase intention of luxury fashion. This research also finds that cultural variables have an impact (mediate) the relationship between status consumption and purchase intention. Specifically, collectivism, uncertainty avoidance, power distance, and masculinity mediate the relationship between status consumption and purchase intention. Finally, the moderating impact of the bandwagon effect has a significant effect on the relationship between status consumption and fashion purchase intention for the cultural variables of uncertainty avoidance, long‐term orientation, and power distance. Implications for marketers are provided based on the findings.     

Are rival team fans a curse for home team sponsors? The moderating effects of fit,oppositional loyalty,and league sponsoring

Sports sponsorship is big business, and a great deal of research provides evidence as to sponsorship’s efficacy in achieving a large range of communication goals, particularly for brands that are perceived as fitting well with the sport by the most involved fans. A developing body of literature, however, suggests that fan passion for a favorite team or athlete might work against the sponsors of hated rivals. The current research contributes to the rivalry effects topic by examining the impact of sponsor-sport fit, business rivalry, and league sponsoring on “home” team fan attitudes towards the sponsors of their team’s main rival. The study finds that negative rivalry effects are particularly severe when the rival team sponsor has high-perceived fit with the sport and is a direct business rival to a “home” team sponsor, but that league sponsorships largely mitigate these rivalry effects.
