The EEC is now a Customs Union

The Customs Union among the member states of the European Economic Community has come into force on July 1, 1968. Its main effect has been the eradication of the ultimate 15 per cent that had remained of the original internal rales of import duty on industrial products between member states and the complete application of the joint tariff of the Community to industrial imports coming from outside the area. Farm produce, which is not subject to import duty but to “Abschöpfungen” (levies) will in future be governed by a unified system of import control. Recently, it has not always been a true community spirit that ruled the fate of the EEC because, in many countries, national selfishness seems to recover ground. This renders more indispensable than ever for the Community a successful completion of the Customs Union, which is thought to be the first big step towards closer political cooperation in Europe.     

Impacts of Hedonic and Utilitarian User Motives on the Innovativeness of User‐Developed Solutions

When individual consumers develop products for their own use, they in part expect to be rewarded by the use value of what they are creating (utilitarian user motives), and in part expect to be rewarded intrinsically by such things as the fun and learning experience derived from creating it (hedonic user motives). This paper shows a first‐of‐type study to understand the relationship between individual consumers' motives to innovate and the novelty and utility of the solutions they develop. The theoretical framework integrates self‐determination theory and goal‐setting theory. The major findings of this study are that utilitarian user motives positively affect the utility of user‐developed innovations. In contrast, hedonic user motives drive solution novelty; the more an innovator is “in it for fun,” the more novel the solution developed. However, hedonic user motives also have an inverted U‐shaped relationship with solution utility. When the dominant motive for developing an innovation is the joy of the creative process rather than use value, the utility of what is developed is negatively affected. These findings are of research interest, and can be of significant practical interest to producers hoping to benefit from user‐developed innovations. For the first time, it has been possible to show that the adjustment of hedonic rewards, for example by means such as gamification, can affect the nature and utility of solutions individuals create.     

Prices vs. quantities: Public finance and the choice of regulatory instruments

Since Montgomery [1972. Markets in licenses and efficient pollution control programs. Journal of Economic Theory 5, 395-418] and Weitzman [1974. Prices vs. quantities. Review of Economic Studies 41, 477-491], it has generally been assumed that, in a full-information setting, tradable quotas and taxes are equivalent regulatory instruments. We demonstrate that, if the government is movitated by public-finance concerns, this equivalence holds only if quotas are short lived. Moreover, the government prefers quotas with the shortest possible lifetime, or, what is equivalent in our setting, taxes.     

An advanced perspective on the predictability in hedge fund returns

This paper advances the research on the predictability in hedge fund returns, using a broad set of risk factors within a variety of different prediction models. Accounting for the fact that returns are non-normally distributed, heteroscedastic and time-varying in their exposure to pervasive economic risk factors, we advocate a non-parametric backward elimination regression approach. The interdependencies between the monthly changes of envisaged risk factors and the subsequent hedge fund returns remain remarkably stable in terms of the observed direction of impact. Thus, taking into account the specific characteristics of this asset class, we find strong evidence of its return predictability.
