The influence of spouses on household decision making under risk: an experiment in rural China

We study household decision making in a high-stakes experiment with a random sample of households in rural China. Spouses have to choose between risky lotteries, first separately and then jointly. We find that spouses’ individual risk preferences are more similar the richer the household and the higher the wife’s relative income contribution. A couple’s joint decision is typically very similar to the husband’s preferences, but women who contribute relatively more to the household income, women in high-income households, and women with communist party membership have a stronger influence on the joint decision.     

Identifying ecological sustainability assessment factors for ecotourism and trophy hunting operations on private rangeland in Namibia

This paper reports on long-term research conducted in Lombok, Indonesia into the social and socio-economic outcomes of tourism development within a heterogeneous community of migrant settlers and native residents. It explores the outcomes of international development agency work in the area. It explains how while most of the case study's tourism attractions are part of the indigenous heritage of the wetu telu Sasak, they derive few economic benefits from that heritage. Local women in particular struggle to access the new development opportunities that tourism offers. Benefits tend to flow to incoming migrant groups and to men. The prevailing conditions of culture, education, ethnicity, gender, politics, history, location, mobility, socio-economy, tourism skills and knowledge constitute key barriers. Further constraints, often overlooked, result from an “institutional culture” within aid projects that promotes business ahead of social development.     

Management Research and Religion: A Citation Analysis

Research on management with regard to religion became a growing field of interest in the last decades. Nevertheless, the impact of religion on actor’s economic behavior is also an old research topic, as the writings of Max Weber (The protestant ethic and the spirit of capitalism, Allen and Unwin, London, 1930) underline. The purpose of this contribution is to highlight the developments of this topic and to guide scholars to identify possible gaps. The structuring and investigation on this topic will help us to advance and better understand past research, while leading to some further reflections. We conduct a citation analysis of 215 articles and 7,968 cited references to examine the citation structure and make out the most-influential publications that have shaped research most so far. On the basis of the analysis it is to be assumed that three research streams affect progress: Best practices regarding performance issues, religion at work as well as religion, and personal ethics. Finally, the publications that each topic-clusters contains are reflected and discussed to achieve a structural overview of the state of the art of research.     

An empirical analysis of multivariate copula models

Since the pioneering work of Embrechts and co-authors in 1999, copula models have enjoyed steadily increasing popularity in finance. Whereas copulas are well studied in the bivariate case, the higher-dimensional case still offers several open issues and it is far from clear how to construct copulas which sufficiently capture the characteristics of financial returns. For this reason, elliptical copulas (i.e. Gaussian and Student-t copula) still dominate both empirical and practical applications. On the other hand, several attractive construction schemes have appeared in the recent literature promising flexible but still manageable dependence models. The aim of this work is to empirically investigate whether these models are really capable of outperforming its benchmark, i.e. the Student-t copula and, in addition, to compare the fit of these different copula classes among themselves.     

Static hedges for reverse barrier options with robustness against skew risk: an empirical analysis

We conduct an empirical evaluation of a static super-replicating hedge of barrier options. The hedge is robust to uncertainty about the future skew. Using almost seven years of current data on the DAX, we evaluate the performance of the hedge and compare it with those of both a dynamic and a static replicating hedge. The main result is that the robustness of the static super-replicating portfolio is also empirically confirmed in practice such that the hedge sets an upper bound for the price of skew risk for barrier options.     

Structural factors associated with primary fiscal balances in developing countries

The study explores the conditions under which a government in a developing country is likely to run a balanced or surplus budget. We contend that primary fiscal deficits are likely to persist where the economy is too saving constrained to raise private sector investment. To conduct the investigation, a logit model is applied to a sample of developing countries to see whether the saving constraints are associated with the fiscal stance of governments. Accordingly, income level, growth, external current account balance and foreign direct investment are used as indicators of the saving constraint. With the exception of economic growth, positive developments in these variables turned out to be significant to the likelihood of the government adopting a surplus budget.     

Efficiency of hospitals in Germany: a DEA-bootstrap approach

Various attempts to assess the performance of German hospitals have generated a wide range of estimates regarding their efficiency. These attempts were based on different, often rather small data sets consisting of heterogeneous hospitals; the techniques applied range from simple benchmarking approaches to studies which employ Data Envelopment Analysis (DEA). Some studies report ‘dramatic differences in efficiency’ and propose savings potentials of 50%; others find an average efficiency in excess of 95% and characterize almost 75% of their observations as fully efficient. This study presents results for two datasets representative of two segments of the German hospital system. These segments comprise all hospitals that have one internal medicine and one surgery department; the hospitals are located in the old federal states of Germany. None of the hospitals provides tertiary care. DEA can be applied because all hospitals offer a comparable quality and range of services. The results were estimated with a DEA-bootstrapping procedure and suggest an average bias–corrected efficiency of around 80%.     

Comprehensive Support for Creativity-Intensive Processes

Creativity is an important precondition of innovation. However, the management of creativity-intensive processes (CIPs) is beyond the scope of standard methodologies for business process standardization and automation because of the contradictory properties of CIPs, which require both process structure and creative freedom. We develop an explanatory design theory based on theoretical constructs from BPM theory, creativity research, and collaboration engineering, with the core component of an integrated IS architecture that facilitates the design of systems providing comprehensive support for CIPs. Automated control of structured processes and support of idea development in groups increase process efficiency and creative performance. Evaluation of a sub-portion of an expository instantiation (CreativeFlow) of the architecture in a laboratory experiment suggests that working with CreativeFlow leads to ideas that are more specific, while working without the tool generates ideas that are more feasible. Further, idea evaluation support of CreativeFlow must be improved in order to increase ideas’ feasibility and relevance. The validity of our theory is derived from a deductive development approach. We indicate limitations and further research.     

PowerPlay: Exploring decision making behaviors in energy efficiency markets

Computer models are widely used to analyze decisions about energy efficiency improvements in the residential and commercial sectors. Few models exist that can actually be run interactively by decision makers to play out alternative future scenarios. None are available that interactively capture the dynamics, subtleties and complexities of interdependent decisions by utilities, households and firms in an ever-changing technological and economic environment.This paper presents the features and experiences of PowerPlay, a computer-facilitated game which fills that gap and does more: it is a game to be played by at least a dozen player groups who interact with each other, make deals (or break them), plan for the future and revise decisions. The computer model functions like a game board to trace actions and offer choices. The observed behaviors can be analyzed to advance understanding of investment strategies and consumer choices; to generate experimentally-based data on energy efficiency changes; and to provide the basis for analyses that can substantiate or complement historical, time-series driven specifications of energy models.
