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.     

The high cost of accurate knowledge

Many business thinkers believe it's the role of senior managers to scan the external environment to monitor contingencies and constraints, and to use that precise knowledge to modify the company's strategy and design. As these thinkers see it, managers need accurate and abundant information to carry out that role. According to that logic, it makes sense to invest heavily in systems for collecting and organizing competitive information. Another school of pundits contends that, since today's complex information often isn't precise anyway, it's not worth going overboard with such investments. In other words, it's not the accuracy and abundance of information that should matter most to top executives--rather, it's how that information is interpreted. After all, the role of senior managers isn't just to make decisions; it's to set direction and motivate others in the face of ambiguities and conflicting demands. Top executives must interpret information and communicate those interpretations--they must manage meaning more than they must manage information. So which of these competing views is the right one? Research conducted by academics Sutcliffe and Weber found that how accurate senior executives are about their competitive environments is indeed less important for strategy and corresponding organizational changes than the way in which they interpret information about their environments. Investments in shaping those interpretations, therefore, may create a more durable competitive advantage than investments in obtaining and organizing more information. And what kinds of interpretations are most closely linked with high performance? Their research suggests that high performers respond positively to opportunities, yet they aren't overconfident in their abilities to take advantage of those opportunities.     

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.     

Property taxes and dynamic efficiency: A correction

According to Kim and Lee (1997), property taxes as opposed to capital gain taxes and taxes on rent endanger dynamic efficiency. The present paper shows that the choice of the tax base is immaterial. What counts is whether the taxes eliminate the after-tax rent. Empirical evidence suggests that this is not the case.     

The impact of stricter criteria for disability insurance on labor force participation

This paper studies the effect of a large-scale policy change in the Austrian disability insurance program, which tightened eligibility criteria for men above a certain age. Using administrative data on the universe of Austrian private-sector employees, the results of difference-in-difference regressions suggest a substantial and statistically significant decline in disability enrollment of 6 to 7.4 percentage points and an increase in employment of 1.6 to 3.4 percentage points. The policy change had important spillover effects into the unemployment and sickness insurance program. Specifically, the share of individuals receiving unemployment benefits increased by 3.5 to 3.9 percentage points, and the share receiving sickness insurance benefits, by roughly 0.7 percentage points.     

Sequential communication with ex post participation constraints

This paper examines an informed principal-agent game with ex post participation constraints for the agent. It shows that the players do not lose by communicating in turn among themselves rather than simultaneously if and only if the principal communicates first. It then considers every Bayesian incentive compatible allocation rules that assign non-negative payoffs for one player in a bilateral asymmetric information framework. It provides necessary and sufficient conditions for sequential communication to be as efficient as simultaneous communication in implementing these allocation rules when the player with unbounded payoffs moves first.
