Short-term persistence in hybrid mutual fund performance: The role of style-shifting abilities

Our study analyzes the performance of hybrid mutual funds. Based on two extended Carhart models we determine total fund performance by comparing fund returns to investable fund-specific style benchmarks. Using daily returns and a quarterly measurement interval, we present an innovative return-based approach to decompose total performance into in-quarter abnormal performance and style-shifting performance. In addition, we split total style-shifting performance into active and passive components. In this context, we confirm possible benefits of these performance measures by analyzing several simulated investment strategies. Our empirical study covers 520 hybrid mutual funds from 10/1998 to 12/2009 and shows that hybrid mutual funds (i) do not outperform their benchmarks on average, (ii) partially show positive in-quarter abnormal performance and style-shifting abilities, and (iii) exhibit short-term persistence in in-quarter abnormal performance but not in style-shifting abilities.     

Alternatives to conventional crude oil: When, how quickly, and market driven?

We examine the effect of uncertainty concerning remaining supplies of conventional crude oil and its production path on: the date alternative fuels will be needed, the quantity of alternative fuels needed, and how this uncertainty affects firms' willingness to provide alternatives in a timely fashion. Despite large uncertainties about the quantity of oil that remains and its production path, the start date for replacements is likely to fall within a twenty-two year period that is narrower and earlier than previous estimates. The twenty-two year window represents considerable uncertainty about the date of the peak and this uncertainty creates an asymmetry in the strategy that maximizes the welfare of firms relative to total social welfare, which works against the market's ability to generate a smooth transition from oil to alternative fuels. The timeliness of this transition is critical—the production paths generated here suggest that 10 million barrels per day or more of alternative fuels will be needed within a decade of the peak in production of conventional crude oil.     

Broke,Ill, and Obese: Is There an Effect of Household Debt on Health?

We analyze the association between household indebtedness and different health outcomes using data from the German Socio‐Economic Panel from 1999 to 2009. We control for unobserved heterogeneity by applying fixed‐effects methods and furthermore use a subsample of constantly employed individuals plus lagged debt variables to reduce problems of reverse causality. We apply different measures of household indebtedness, such as the percentage shares of household income spent on consumer credit and home loan repayments (which indicate the severity of household indebtedness) and a binary variable of relative overindebtedness (which indicates a precarious debt situation). We find all debt measures to be strongly correlated with health satisfaction, mental health, and obesity. This relationship vanishes for obesity after controlling for unobserved heterogeneity while it stays significant with respect to worse physical and mental health.     

Japanese retailers in Southeast Asia: strong local partners,shopping malls,and aiming for comprehensive internationalization

Japanese retailers have a long and mixed history in Southeast Asia with a period of expansion in the 1980s and 1990s being followed by a long period of decline and stagnation. Recently, some Japanese retailers have renewed their interest in Southeast Asia. Based on an overview of the major retail trends in Southeast Asia and identification of those Japanese retailers that are currently expanding in the region, this article develops propositions about the underlying factors and processes. It argues that the interest in Southeast Asia, while being mostly justified by retailers through reference to the growing middle-class populations in host countries, is as much based on developments in Japan itself, such as the saturation and stagnation of markets and the emergence of exportable, flexible, and comprehensive business models. Japanese retailers are intensifying activities at a time when strong domestic companies with retail interests have established themselves in host countries and therefore partnerships with them seem to fulfill more than the need to comply with investment regulations or deal with complex environments. Shopping malls play a role as locations for specialty stores but are also transplanted from Japan. Companies are making efforts toward more comprehensive internationalization and this involves human resources in headquarters in Japan as well as working together with other Japanese companies, thus satisfying the need for local embeddedness but at the same time maintaining corporate identity and advantages.     

The impact of buyer–seller relationships and reference prices on the effectiveness of the pay what you want pricing mechanism

Pay what you want (PWYW) is a new participative pricing mechanism that delegates the whole price determination to the buyer. Previous research on PWYW suggests that the final prices paid are not only affected by consumer characteristics but also by varying conditions, such as social distance within buyer–seller relationships and the provision of reference prices. Through an online survey and two field experiments, we test varying conditions of PWYW, such as social distance (buyer–seller relationship), provision of external reference price, product value, level of reputation, and duration of an application of PWYW. The results indicate that the provision of an external reference price is advantageous for the seller as the prices paid increase. The seller should also avoid offering products with high product value under PWYW conditions. Furthermore, increasing social distance may decrease the prices paid. Finally, a high level of reputation may be beneficial.     

South Korean social enterprises and their networks: On their organizational linkages at the interstice between the third,public, and corporate sectors

Social enterprise and government interactions have become an increasingly prominent theme in the literature on social entrepreneurship, due in part to the pressures confronting the welfare state and the rise of precarious work. This analysis is motivated by the efforts of the government of South Korea to incubate social enterprises since 2007. The constant scaling of the South Korean government's monitored social enterprise certification scheme had led to the registration of approximately 3440 social enterprises as of May 2021. This study documents the interorganizational network behaviour of these enterprises relative to the public sector, corporate sector, and civil society and the social economy. A cluster analysis approach is utilized to analyse network data obtained from a self-administered survey of 103 government-certified social enterprises operating in South Korea. We find that a sizeable number of government-certified social enterprises have diversified networks, as opposed to public sector-centric networks, although such social enterprises are in the minority. This study references social innovation cluster theory to argue that the aforementioned scheme has attained a partial degree of success in facilitating the emergence of social enterprises with diversified networks.However, the majority remain quasi-governmental implementers of government contracts and, generally, do not engage in networking.
