Changing rewards in contests: Has the three-point rule brought more offense to soccer?

In the mid-nineties FIFA decided to increase from two to three the number of points assigned to the winning team of a soccer match played under traditional round-robin national leagues. Since a game of soccer can be regarded as a contest, FIFA's measure provides an interesting case-study for analysing how a change in the system of rewards (from a zero to a non-zero sum rule) may affect the contestants' equilibrium behaviour. In this paper we try to assess, both theoretically and empirically, whether FIFA's new point rule has changed soccer towards a more offensive game, in which teams adopt more risky strategies. In particular, we evaluate the “na?ve hypothesis” according to which the measure would induce every team to play always more offensively, and we explore the extent to which the change in teams' behaviour may be affected by quality differentials between teams. Our most important hypothesis is that when the asymmetry between opposing teams is large enough, an increase in the reward for victory induces the weaker team to play more defensively, rather than the opposite. By looking at a subset of matches held in the Portuguese first division league, which approximate the conditions of our model, we find support for this hypothesis.

Assessing Systemic Importance With a Fuzzy Logic Inference System

Three metrics are designed to assess Colombian financial institutions' size, connectedness and non-substitutability as the main drivers of systemic importance: (i) centrality as net borrower in the money market network; (ii) centrality as payments originator in the large-value payment system network; and (iii) asset value of core financial services. An aggregated systemic importance index is calculated based on expert knowledge by using a fuzzy logic inference system. We use principal component analysis to calculate a benchmark index for comparison purposes. Overall similarities between both indexes put forward that expert knowledge aggregation is consistent with that based on a purely quantitative standard approach. Specific non-negligible differences concur with the nonlinear features of an approach whose intention is to replicate human reasoning. Both indexes are complementary and provide a comprehensive relative assessment of each financial institution's systemic importance in the Colombian case, in which the choice of metrics pursues the macroprudential perspective of financial stability.

TESTING THE INDUCED INNOVATION HYPOTHESIS USING COINTEGRATION ANALYSIS

This paper deals with some of the problems involved in testing the hypothesis that factor price movements tend to influence the type of technological innovations which are developed and adopted, known as the Induced Innovation Hypothesis. Previous methods to perform this test are briefly reviewed and their limitations are discussed. A testing procedure which is based on the use of cointegration analysis is proposed and its advantages outlined. Finally, one application of the method is made, providing little support for the Induced Innovation Hypothesis in the case of US Agriculture (1948–83).     

The Influence of Innovative Organizational Culture on Marketing Strategy Formulation and Results

ABSTRACT

This article's objective is to analyze the influence innovative organizational culture has on marketing strategy formulation and results, and how this relationship affects organizational performance. The theoretical basis lies in Menon et al.'s (1999 Menon , A. , Bharadwaj , S. G. , Adidam , P. T. , and Edison , S. W. ( 1999 ). Antecedents and consequences of marketing strategy making: A model and a test . Journal of Marketing , 63 , 18 – 40 .[Crossref], [Web of Science ®] , [Google Scholar]) model. The methodology included a survey with medium to large Brazilian companies in different sectors. The final sample consisted of 153 questionnaires that were valid for analysis. Techniques for statistical analysis including singular and multivariate methods were used, from which the relationships between constructs were established by structural equation modeling. Results show a positive relationship between innovative organizational culture, the marketing strategy process, and organizational performance. However, innovative culture does not have a direct influence on performance.     

Factors affecting success in the professional entry exam for accountants in Brazil

This paper explores factors that have affected the success of candidates in the professional entry exam conducted by Brazil’s Federal Council of Accounting. We analyse results of 18,948 candidates who sat for the exam in 2012, using a logistic regression model and the key indicators used by government to monitor the performance of higher education institutions (HEIs) and the characteristics of candidates. We find that success is related positively to the quality of the HEIs from which candidates graduated and to a measure of student ability that is used widely in Brazil. We find also that males perform better than females and that younger candidates perform better than older candidates. The geographical region of Brazil within which candidates completed the exam was also significant. The insights provided will help public policy-makers in Brazil, and the Brazilian accounting profession, to understand key factors associated with current low pass rates.     

Counterfactual decomposition of changes in wage distributions using quantile regression

We propose a method to decompose the changes in the wage distribution over a period of time in several factors contributing to those changes. The method is based on the estimation of marginal wage distributions consistent with a conditional distribution estimated by quantile regression as well as with any hypothesized distribution for the covariates. Comparing the marginal distributions implied by different distributions for the covariates, one is then able to perform counterfactual exercises. The proposed methodology enables the identification of the sources of the increased wage inequality observed in most countries. Specifically, it decomposes the changes in the wage distribution over a period of time into several factors contributing to those changes, namely by discriminating between changes in the characteristics of the working population and changes in the returns to these characteristics. We apply this methodology to Portuguese data for the period 1986–1995, and find that the observed increase in educational levels contributed decisively towards greater wage inequality.

Structural VAR Estimation with Exogeneity Restrictions

ABSTRACT Exogenous variables arise quite naturally in macroeconomic models of small open economies. In these models overidentification is also a common feature. In the presence of exogeneity restrictions and overidentification the usual two-steps approach to the estimation of structural VAR's is not equivalent to Maximum Likelihood (ML). We propose a simple modification of that usual approach which produces ML estimators.     

CO-INTEGRATION ANALYSIS AND THE DETERMINANTS OF LAND PRICES

This paper outlines the concept of co-integration and its use in econometric modelling. The techniques of co-integration analysis are described, with particular emphasis given to test procedures. Co-integration between two or more variables is taken to imply the existence of a long-run equilibrium relationship between them. Co-integration analysis is applied in a re-examination of recent empirical models of the determination of land prices in England and Wales. The results suggest that recent land price models do not describe longrun relationships between land prices and the explanatory variables selected. Criticisms of the different measurements of returns to land used in studies to date are sustained by the analysis, and a clear role for interest rates in the determination of land prices is indicated.
