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.     

Moral economics

An adequate normative economics – one that is consistent with recent developments in our discipline (and in philosophy and psychology) and that resonates with widely held moral intuitions – will have to address the following challenges. First, utility cannot be both the basis of our predictions of economic behaviour and the evaluation of the outcomes of this behaviour. Second, we need to conceive of individual well-being and other desiderata in ways that are interpersonally comparable and that go beyond efficiency and fairness. Third, the representation of the economy as a ‘morality-free zone’ (requiring that contracts, including employment contracts, are complete) must give way to a recognition of the unaccountable exercise of power by private actors, even in a perfectly competitive equilibrium, and the way that this may violate democratic principles and limit the freedom and compromise the dignity of other actors. Fourth, the commitment to ‘liberal neutrality’ (thereby sidestepping the evaluation of preferences) and the related assumption of ‘unrestricted preferences’ in mechanism design and public policy must be abandoned, making room for a concern about the nature of our preferences and the ways that institutions shape our values.

Monetary,fiscal, and structural drivers of inflation in Ethiopia: new empirical evidence from time series analysis

This study empirically investigates the drivers of inflation in Ethiopia using monthly data over the period July 1998 to September 2020. It explores short-run and long-run effects of domestic and external determinants of inflation—including demand-side, supply-side, and structural factors—using the cointegration and vector error-correction methodology. Four measures of inflation are considered: cereals, food, nonfood, and all-items Consummer Price Index (CPI) inflation. A key contribution to the existing literature is the investigation of the role of the fiscal sector in modeling inflation, a topic that has been neglected in the existing studies on inflation in Ethiopia. The empirical results show that disequilibria in the monetary sector, grains sector, and food markets have long-run effects on inflation. In the short run, inflation is driven by structural factors (notably, cereal output gaps and imported inflation) as well as demand-side factors (notably, money growth and public sector borrowing). The results hold when analysis is limited to the high growth period from 2005 onward, following the end of the International Monetary Fund (IMF) program in the country. The evidence provides valuable insights in the context of ongoing macroeconomic policy reforms in Ethiopia.     

Information sharing offices and economic growth in sub-Saharan Africa

Although credit availability is essential for economic growth, the information asymmetry problem inhibits the credit creation function of financial institutions. Among other means, information-sharing offices (ISOs) have been established, including private credit bureaus and public credit registries to provide information on the financial characteristics of citizens to reduce information asymmetry. From this background, this study used an explanatory research design with a longitudinal (panel) data approach to assess whether the coverage of information by ISOs affects sectorial and overall economic growth among sub-Saharan African (SSA) countries using the system generalized method of moments technique on data from 2005 to 2019. The results highlight that information coverage by ISOs enhances sectorial and overall economic growth by solving the information asymmetry problem. From the findings, governments in SSA countries are encouraged to support public credit registries to effectively perform their mandate while providing incentives to attract investments in private credit bureaus since they contribute to economic growth.

Bailouts and the modeling of bank distress

In this article, we develop a model for predicting distress events among large banks. We show that a bailout possibility induces different behaviors among small and large banks, and the proposed failure prediction model for large banks is thus considerably different from that for small banks. Major bank-level fundamentals show opposite conjecture directions for large versus small banks. The Tier 1 capital ratio, which is under the scrutiny of regulators and investors, has almost no distress prediction power among large banks. However, banks rescued by governments tend to maintain a lower Tier 1 ratio. The cost of funding in large banks is negatively correlated with the probability of failure, reflecting the fact that lenders internalize the too-big-to-fail (TBTF) policy and demand a lower interest rate from TBTF banks.     

Influence of family-centered goals on dividend policy in family firms: A socioemotional wealth approach

Socioemotional wealth (SEW) preservation is likely to be a key determinant for family firms when shaping their dividend policy. This paper analyzes how family-centered goals reflected by SEW can influence dividend policy in private family firms and explores how family involvement in management, generational stage, and firm hazard might moderate these relationships. Results indicate a negative association between SEW preservation and both the likelihood of giving dividends and the amount of dividend paid. This negative relationship is stronger when the CEO is a family member, in early generational stages and when the firm faces greater performance hazard. The amount of dividend paid is also lower when there are family members in other top management positions apart from the CEO. The evidence provided thus suggests that the existing heterogeneity in dividend policy in privately held family firms is strongly driven by differences in SEW priorities.
