A Multicriteria Selection System Based on Player Performance: Case Study—The Spanish ACB Basketball League

In this paper, we describe an approach to rank sport players based on their efficiency. Although is extremely useful to analyze the performance of team games there is no unanimity on the use of a single index to perform such a ranking. We propose a method to summarize the huge amount of information collected at different aspects of a sport team which is almost daily publicly available. The tool will allow agents involved in a player’s negotiation to show the strengths (and weaknesses) of the player with respect to other players. The approach is based on applying a multicriteria outranking methodology using as alternatives the potential players and as criteria different efficiency indices. A novel automatic parameter tuning approach is detailed that will allow coaches and sports managers to design templates and sports strategies that improve the efficiency of their teams. We report the results performed over the available information on the ACB Basketball League, and we show how it can be easily implemented and interpreted in practice by decision-makers non familiar with the mathematical side of the methodology.     

Does Shariah compliance make interest rate sensitivity of Islamic equities lower? An industry level analysis under different market states

This paper examines the sensitivity of the Dow Jones Islamic market index and its corresponding industry equity indices to changes in the level, slope and curvature of the U.S. term structure of interest rates over the period 1996–2015 using the quantile regression approach. The empirical results reveal that the Islamic stock market has a considerable negative exposure to interest rate risk, although a declining time pattern of interest rate sensitivity is observed. The unexpected changes in the level factor of the U.S. yield curve, closely linked to long-term interest rates, are identified as the most important interest rate factor in explaining the variability of Islamic equity returns. Furthermore, the interest rate exposure tends to be stronger during extreme bearish conditions in the stock market, possibly due to the greater pessimism and risk aversion under these market circumstances. It is also shown that Islamic equities are not different from their mainstream counterparts in terms of interest rate sensitivity, indicating that the Islamic stock market does not provide a cushion against interest rate risk.     

The Spanish monarchy as a contractor state in the eighteenth century: Interaction of political power with the market

Abstract

The concept of the contractor state has been formulated to underline the existence of a necessary relation between state and private markets in the eighteenth century. Although all states acted as contractors in this period, it is necessary to clarify the relationship between the rulers and the market. Significant differences can be observed between parliamentary governments, which were comfortable with this situation, and the absolute monarchies, which constantly tried to interfere. The Spanish monarchy belongs to the second type, as this article tries to prove. This is a study about such a situation’s relevance and consequences with regard to the provision of uniforms for the army in particular, and for Spanish economic growth in general.

The Visible Hand of corporate entrepreneurship in state-owned enterprises: a longitudinal study of the Spanish National Postal Operator

This study explores how the corporate entrepreneurship (CE) of state-owned enterprises (SOEs) evolves under varying conditions of state ownership and control, laws and norms, and competence in the market. For this purpose, we present a longitudinal case study focused on the Spanish postal operator Correos using qualitative archival data and interviews. Our results indicate that the willingness and capacity of an SOE to act entrepreneurially depends critically on its degree of autonomy from the state and on the extent to which its legal and market environments increase its dynamism, complexity, and hostility. We also show that the development of CE in an SOE may lead to improved service quality, operational efficiency, and business specialization; facilitate its market positioning; and foster its sustainability through the exploration and exploitation of strategic alliances that can increase its business scope.

Heterogeneity in property tax capitalization: Evidence from municipalities in Wisconsin

This article provides evidence that higher property taxes usually decrease property value. On average, a 10% increase in property taxes decreases property value by more than 0.34%. To control for school quality and related sorting, we estimate within-school-district property tax impacts. The effective cost of services (driven by appraisal errors or tax code changes), preferences for local services, and the elasticity of supply of housing all play an important role in determining whether property taxes increase or decrease house prices. Locally produced and consumed municipal services such as trash collection are positively capitalized.
