A curriculum model for IT infrastructure management in undergraduate business schools

As information technology infrastructure becomes strategic to organizations, the author examines business-school programs that educate future infrastructure analysts. Information systems (IS) 2010 and information technology (IT) 2008 curriculum models are used to survey courses required by telecommunications and IT infrastructure programs in business schools. Of 525 Association to Advance Collegiate Schools of Business–accredited schools, 259 have IS/IT programs and 18 have telecommunications and infrastructure-related programs. IT Infrastructure, Networking-Advanced, and IT Security are the top three infrastructure-related courses. Programs also require courses including IS Project Management; Social and Professional Issues; and IS Strategy, Management and Acquisition. Data collected are used to develop a new curriculum model of IT infrastructure management program that can be offered by business schools.     

Institutional dimensions and conflict resolution strategy in international joint ventures: An empirical examination

This study examines the impact of the host‐country institutional structures on the choice of conflict resolution strategy in the international joint venture (IJV). Using the survey method and relying on multiple regression, we demonstrate that there is a statistically significant relationship between institutional pillars and the choice of conflict resolution strategy in the international joint venture in the context of Ghana. In particular, we demonstrate that legalistic and forcing conflict resolution strategies are influenced by the regulative institutional pillar, while compromising and problem‐solving conflict resolution strategies are impacted by normative and cognitive institutional pillars. The multigrouping analysis results show that the views and the choice of foreign partners on conflict resolution strategy differ from that of the local partners to the IJV. This study fills the gap by empirically testing the conflict resolution strategies of firms in relation to the role of regulative, normative, and cognitive institutional pillars of the host country.     

Sharecropping was sometimes efficient: sharecropping with compensation for improvements in European viticulture†

There is no consensus among specialists in agricultural contracts over whether the long‐term inefficiencies that classical economists attributed to sharecropping actually exist. This article maintains that they do exist and are partly caused by the fact that sharecropping is hardly compatible with the tenant being compensated for improvements, viticulture being the main historical exception. In line with recent contributions to the sharecropping literature, the article contends that the widely held belief among scholars of agricultural contracts that sharecropping was very frequent in Europe's vineyards is incorrect. However, it also provides evidence of an issue whose importance has gone largely unnoticed: prior to the twentieth century, many of the European vineyards worked by sharecroppers had been created by the sharecroppers themselves, through contracts which entitled them to compensation. Those contracts abounded while viticulture depended basically on two inputs, land and labour. When viticulture became a heavy consumer of capital, they were rapidly abandoned, but not in Catalonia, with a paradoxical result: the Catalan rabassa morta contract, which for centuries had made it possible to eliminate both the long‐ and short‐term inefficiencies of sharecropping, ended up becoming an obstacle to overcoming the short‐term inefficiencies. The article discusses why that happened.     

Financial Analysts' Earnings Forecast Dispersion and Intraday Stock Price Variability Around Quarterly Earnings Announcements

This study investigates the relationship between the dispersion of analysts' earnings forecasts and stock price variability around quarterly earnings announcements. Consistent with theoretical predictions, the empirical analysis shows that stock price variability at the time of earnings announcements is positively related to the degree of analysts' predisclosure earnings forecast dispersion. Additionally, firms with high levels of forecast dispersion exhibit significant increases in price variability for longer periods prior to and following earnings announcements than do firms with low levels of forecast dispersion. These results suggest that there is information about the earnings announcement that becomes available to at least a subset of investors prior to the earnings release and that market participants take different amounts of time to process the information conveyed by the earnings announcement.     

Understanding and modifying beliefs about climate change through educational travel

Understanding the factors that shape individuals’ beliefs about climate change is key to the development of effective climate change communication and education strategies. In this study, we test a path model of the social psychological antecedents of beliefs about climate change and evaluate the effectiveness of an educational travel program in changing them. Results show that environmental worldview and affective association with nature are two significant predictors of students’ belief in the occurrence of climate change. Gender was found to influence belief in an anthropogenic causation, while political orientation was a significant predictor of conviction that climate change is occurring. Regression analysis was used to test for changes in climate beliefs before and after participation in an educational travel experience, compared to a control group, using a quasi-experimental design. Results indicate participation strengthened climate change beliefs.     

International Technology Diffusion: Theory and Measurement

We model the invention of new technologies and their diffusion across countries. In our model all countries grow at the same steady-state rate, with each country's productivity ranking determined by how rapidly it adopts ideas. Research effort is determined by how much ideas earn at home and abroad. Patents affect the return to ideas. We relate the decision to patent an invention internationally to the cost of patenting in a country and to the expected value of patent protection in that country. We can thus infer the direction and magnitude of the international diffusion of technology from data on international patenting, productivity, and research. We fit the model to data from the five leading research economies. A rough summary of our findings is that the world lies about two-thirds of the way from an extreme of technological autarky to an extreme of free trade in ideas. Research performed abroad is about two-thirds as potent as domestic research. Together the United States and Japan drive at least two-thirds of the growth in each of the countries in our sample.     

Informational externalities and emergence of consensus

We study a general model of dynamic games with purely informational externalities. We prove that eventually all motives for experimentation disappear, and provide the exact rate at which experimentation decays. We also provide tight conditions under which players eventually reach a consensus. These results imply extensions of many known results in the literature of social learning and getting to agreement.     

CREDIT MARKET IMPERFECTIONS AND THE INCIDENCE OF WORKER-OWNED FIRMS

Under plausible conditions, in a market economy with both democratic and capitalist firms, credit market imperfections imply that the fraction of workers in democratic firms is an increasing function of the share of worker wealth. Our analysis addresses two agency problems that all firms must solve: eliciting effort from a team of workers and choosing the appropriate level of risk, in a situation where neither effort nor risk is contractually specified. The democratic firm enjoys a relative advantage in dealing with the agency problems surrounding labor, while the capitalist firm has a relative advantage in dealing with agency problems involving risk-bearing.
