Problematische Umsetzung der Gesundheitsreform

Zusammenfassung   Als ein wesentliches Element der Gesundheitsreform wird am 1. Januar 2009 ein Gesundheitsfonds zur Finanzierung der Gesetzlichen Krankenversicherung eingeführt. Derzeit werden wichtige Weichen für die Gesundheitsreform gestellt. Wie ist es zu der Entscheidung für einen Gesundheitsfonds gekommen? Welche Probleme k?nnen durch die Gesundheitsreform gel?st werden und welche werden neu geschaffen? Wird der Wettbewerb im Krankenversicherungssystem gest?rkt? Welche Anreiz- und Budget- Wirkungen hat die Honorarreform? In welche Richtung zeigen die Strukturwandlungen im Sozialversicherungssystem? Die Autoren unseres Zeitgespr?chs: Prof. Dr. Wolfram F.

Institutional Investors' Preferences for REIT Stocks

This article investigates the determinants of real estate investment trusts (REIT) portfolio investment and institutional REIT ownership using multivariate Tobit regressions. We contend that many institutional investors take larger positions in more liquid assets like REIT stocks, as compared with private real estate equities, because of liquidity considerations. Consistent with this contention, we find that liquidity constraints are significantly related to REIT portfolio investment by institutional investors. We also find that institutional investors have different preferences for REIT stocks than do other investors; they generally prefer larger, more liquid REIT stocks.     

Family and sex-specific U.S. immigration from Europe, 1870–1910: A panel data study of rates and composition

This paper develops and estimates models of family and sex-specific emigration, as well as the sex composition of this emigration, from 12 European source countries to the U.S. for the period 1870–1910. The models are based on the distinction between economic migrants (males, single females, and some married females) and tied or trailing migrants (females) and are estimated with panel data, including data that relate to the occupational/industrial structure of male and female economic activity in source countries. Hausman-Taylor instrumental variable estimates suggest that although both males and females responded to labor-market signals, males were more responsive than females to per capita GDP differences. Moreover, compared to the rest of Europe, Ireland, and Scandinavia were the sources of many young, single male, and female migrants, who responded strongly to gaps in economic opportunities. In fact, much of the European response to such gaps appears to be due to migrants from Ireland and Scandinavia. Females tended to originate in English-speaking countries and countries that were agriculturally oriented. Service and manufacturing jobs in source countries discouraged the migration of females relative to males. Males tended to follow recent migrants more than females, but females responded more to long-term influences as measured by stocks of migrants from their source countries who had previously settled in the U.S. Countries with high birth rates had relatively fewer female emigrants, whereas those with high rates of natural increase 20 years earlier experienced relatively more male emigration. Intact families, other family members (including family-strategy male migrants and trailing female migrants), and single males and females responded strongly to economic incentives, but the singles were most responsive followed by family-strategy males.     

Risk Arbitrage in Takeovers

This article studies the role of risk arbitrageurs in takeoversand the source of their advantage. We show how the presenceof arbitrageurs affects the value of the target shares, sincearbitrageurs are more likely to tender. Therefore an arbitrageurhas the informational advantage of knowing he bought shares.In equilibrium, the number of arbitrageurs buying shares andthe price they pay are determined endogenously. We also presentseveral empirical implications, including the relationship amongtrading volume, takeover premium, liquidity of the shares, andthe number of risk arbitrageurs investing in one particulardeal.     

Managerial Ownership, Information Content of Earnings, and Discretionary Accruals in a Non–US Setting

This study employs Danish data to examine the empirical relationship between the proportion of managerial ownership and two characteristics of accounting earnings: the information content of earnings and the magnitude of discretionary accruals. In previous research concerning American firms, Warfield et al. (1995) document a positive relationship between managerial ownership and the information content of earnings, and a negative relationship between managerial ownership and discretionary accruals. We question the generality of the Warfield et al. result, as the ownership structure found in most other countries, including Denmark, deviates from the US ownership configuration. In fact, Danish data indicate that the information content of earnings is inversely related to managerial ownership.
