Modelling soccer matches using bivariate discrete distributions with general dependence structure

In this paper copulas are used to generate bivariate discrete distributions. These distributions are fitted to soccer data from the English Premier League. An interesting aspect of these data is that the primary variable of interest, the discrete pair shots-for and shots-against, exhibits negative dependence; thus, in particular, we apply bivariate Poisson-related distributions that allow such dependence. The paper focuses on Archimedian copulas, for which the dependence structure is fully determined by a one-dimensional projection that is invariant under marginal transformations. Diagnostic plots for copula fit based on this projection are adapted to deal with discrete variables. Covariates relating to within-match contributions such as numbers of passes and tackles are introduced to explain variability in shot outcomes. The results of this analysis would appear to support the notion that playing the 'beautiful game' is an effective strategy—more passes and crosses contribute to more effective play and more shots on the goal.     

Managing academic innovation in Taiwan: Towards a ‘scientific-economic’ framework

Since the passage of the Science and Technology Basic Law in 1999, Taiwanese universities have taken a more “scientific-economic” approach to protect and commercialize their research. This research mainly examines innovation activities such as patenting, licensing, and incubated startups in the context of Taiwanese higher education institutions (HEIs). The “scientific-economic” framework used to analyze the strategic aspects influencing these academic innovations includes (1) intellectual property managerial capabilities, (2) the strength of external industrial partnerships, (3) the university entrepreneurial orientation, and (4) government research policy. Four hypotheses were developed. Data were collected via a questionnaire with all 122 HEIs in Taiwan surveyed.The research reveals that the aspects of intellectual property managerial capability, HEI-industry partnerships, and academic entrepreneurial orientation are useful to distinguish the university's innovation performance on patent grants, licensing incomes, and firm incubation. Also, government support on research plays a moderating role in academic innovation. Managerial and policy implications for managing innovation effectively in universities were drawn.     

Keeping Public Institutions Invested in Tobacco

Increasingly through the 1990s, tobacco control advocates questioned the practice of public institutions investing in tobacco company stocks. The questioning was framed in at least three ways. First, is it ethical to fund public expenditures with profits from a product that causes addiction and disease? Second, is it sound social policy to derive public income from a product that increases healthcare costs and reduces worker productivity? Finally, is it sound fiscal policy to invest in an historically profitable industry facing multiplying legal and regulatory challenges? While the tobacco industry preferred to restrict discussion to the fiscal question, and offered an affirmative answer, its position was weakened by depressed stock prices brought on by actions of the industry as much as by tobacco control activism. As part of a campaign to restore its credibility as an investment vehicle with public fund managers, Philip Morris (PM) commissioned a report from the influential investment managers/advisors Wilshire Associates. However, Wilshire had only recently conducted such a study for the Washington State Investment Board (WSIB), assuring the board that the value tobacco stocks added to an investment portfolio – if any – was too small to be measured. Nonetheless, within a year, Wilshire produced a report for PM which appeared to laud the investment value of tobacco and to dismiss tobacco-excluded investment alternatives. This paper examines how Wilshire produced apparently diametrically opposed reports for clients with different interests. It reveals a pattern of potential conflicts of interest among tobacco companies, financial analysis firms, investment authorities, and institutional fund managers. It demonstrates substantial violations of two generally accepted ethical principles of business consulting: veracity and transparency.     

Impacts of Market Reform on Spatial Volatility of Maize Prices in Tanzania

Maize is one of the major staples and cash crops for many Tanzanians. Excessive volatility of maize prices destabilises farm income in maize‐growing regions and is likely to jeopardise nutrition and investment in many poor rural communities. This study investigates whether market reform policies in Tanzania have increased the volatility of maize prices, and identifies regional characteristics that can be attributed to the spatial price volatility. To achieve the objectives, an autoregressive conditional heteroskedasticity in mean (ARCH‐M) model is developed and estimated in this study. Results show that the reforms have increased farm‐gate prices and overall price volatility. Maize prices are lower in surplus and less developed regions than those in deficit and developed regions. Results also show that the developed and maize‐deficit regions, and regions bordering other countries have experienced less volatile prices than less developed, maize‐surplus and non‐bordering regions. Our findings indicate that investments in communication and transportation infrastructures from government and donor countries are likely to increase inter‐regional and international trade, thereby reducing the spatial price volatility in Tanzanian maize prices in the long run.     

Embedding multinational firms in regional business systems: neoliberal and social‐democratic models in Spain

The paper analyses how regional actors have mobilised to attract and retain foreign direct investment in two Spanish regions with different political approaches to the management of economic issues, including industrial relations. These regions are Madrid, the main pole of attraction of foreign direct investment in Spain, and Asturias, with a large tradition of heavy industry and a greater dependence on a small number of large employers. It finds the regions have adapted to international competition in substantially different manners and considers the alternative reasons why this might be the case, highlighting the role of organised labour both in the inward investment regimes themselves, and in shaping the nature of the different compromises they involve.     

An instrumental variable approach to distinguishing perceptions from preferences for beer brands

Recent developments in behavioral economics have prompted interest in identifying how product perceptions and beliefs influence decision making. Using a branded discrete choice experiment for beer, this article uses the control function approach and plausible instruments to correct for the endogeneity problem in a way that is applicable in a wide range of circumstances. Even after correction, we find that perceptions substantially affect consumer choices. In the context of brand equity for beer brands, we find that the perceived taste and brand familiarity are key determinants of choice.     

Retail fairness: Exploring consumer perceptions of fairness towards retailers’ marketing tactics

The concept of fairness has received great attention in consumer behavior research lately. However, the focus of these studies has mainly been the understanding of fairness in terms of pricing rather than exploring the consumers’ perceptions of fairness itself. This study explores the consumers’ perceptions of fairness as an outcome of a retailer’s marketing tactics. Based on 36 in-depth interviews this study submits a conceptualization of retail fairness from the consumers’ point-of-view. The concept of retail fairness constitutes of three dimensions and nine sub-dimensions, expanding our knowledge of the construct. The study posits a crucial link between increased honesty, ethical, and moral behavior and the understanding of retail fairness. Theoretical and managerial implications are discussed.
