Incentives to Reduce Crop Trait Durability

To reduce the competition from farmers who self-produce seed, an inbred line seed producer can switch to nondurable hybrid seed. In a two-period framework, we first investigate the impact of crop durability on self-production, pricing and switching decisions. Second, we study how the introduction of a fee paid by self-producing farmers affects those decisions. We find that the monopolist may produce technologically dominated hybrid seed in order to extract more surplus from farmers. Further, the introduction of a self-production fee improves efficiency.     

Internationalization of Blue-Chip versus Mid-Cap Stock Indices: an Empirical Analysis for France,Germany, and the UK

The paper analyzes the question whether blue-chip stock indices provide a larger degree of internationalization than mid-cap stock indices. Specific focus lies on internationalization of indices in France, Germany, and the UK. Additionally, we analyze whether the degree of internationalization differs between industries. The dataset covers the CAC40, the DAX30 and the 30 largest firms in the FTSE100 as blue-chip indices and the CAC Next 20 and CAC Mid 60, the MDAX and TecDAX, and the remaining 70 companies in the FTSE100 as mid-cap indices. The comparison of blue-chip and mid-cap indices is based on three indicators of internationalization: percentages of employees based outside the firms’ home country, percentages of foreign sales, and percentages of foreign corporate tax payments. Blue-chip and mid-cap indices exhibit high levels of internationalization. Internationalization is stronger in German and UK blue-chip indices than in these countries’ mid-cap indices, whereas internationalization in French mid-cap and blue-chip indices is similar. Blue-chip and mid-cap firms in the energy/materials/utilities and industrials sectors exhibit similar levels of internationalization, whereas blue-chip firms in the consumer and health sectors exhibit higher levels than corresponding mid-cap firms. The research question and results are of particular importance for retail and institutional investors, because investing in indices typically represents a low cost alternative to individual stock picking. The question whether stock index characteristics, such as market capitalization and industry, influence the degree of international diversification within the index is largely unanswered in the literature. The paper addresses this question.     

On the public provision of the performing arts

In this paper, we present a model in which the performing arts are modelled as congestible public goods. In accordance with empirical evidence, the production of seat capacity is assumed to be subject to fixed costs. We estimate the parameters of the model's demand and cost functions using German data. Using these estimates in a subsequent social choice analysis, we show that the current situation in the German performing arts sector is best described by a directorship that under the influence of a selfish theater lobby maximizes only the welfare of the spectators. Such an equilibrium, characterized by too low ticket prices and too large capacity, is most likely to establish if citizens have a very positive ex ante notion of the performing arts.     

Mutual Fund Growth in Standard and Specialist Market Segments

This paper is concerned with differences in the performance-flow relationship (PFR) between standard and specialist market segments of the mutual fund industry. We expect differences in this relationship because investor characteristics might vary across different segments. Our results show that the PFR is more convex in standard segments than in specialist segments. Furthermore, investors in standard segments are less risk-averse and invest more in high-load funds than investors in specialist segments. Our findings are consistent with investors in standard segments being less sophisticated than investors in specialist segments and relying more heavily on the advice of financial brokers, which is compensated for by load fees.
