Gibrat's law test on Brazilian commercial banks

In recent years, Brazil has been one of the countries with the biggest changes in the banking sector. The process of deregulation that began in 2002 has entailed the increase of the presence of foreign banking and the increase of competition, among other aspects. In this context, the objective of this study consists in contrasting Gibrat's Law in the Brazilian commercial banking during the period of 2002–2013 with the objective of contributing with evidence for the construction of a growth model for banking that will guide the financial policy of the country. For this, the quartile regression methodology is utilized, since we consider that it analyzes the relation between growth and the size of the entities more thoroughly than the empirical contrasts given by previous empirical evidence. The results obtained indicate that there is a non-linear relation in an inverted U form between growth and size in the Brazilian commercial banking. These results allow us to affirm that the relative dispersion of the sizes of the financial entities will tend to decrease in time and with this, the concentration of the sector.     

Fractional integration and cointegration in US financial time series data

This paper examines several US monthly financial time series using fractional integration and cointegration techniques. The univariate analysis based on fractional integration aims to determine whether the series are I(1) (in which case markets might be efficient) or alternatively I(d) with \(d < 1\) , which implies mean reversion. The multivariate framework exploiting recent developments in fractional cointegration allows to investigate in greater depth the relationships between financial series. We show that there might exist many (fractionally) cointegrated bivariate relationships among the variables examined, for some of which only standard cointegration tests had previously been carried out.     

Pension Fund Herding and the Influence of Management Style

In this article, we study the herding phenomenon in Spanish equity pension funds with European investment locations from 2002 to 2012, considering whether the development of different investment strategies by the managers results in herding. In addition, we analyze the performance-herding relationship, observing whether pension fund performance decreases or increases when pension funds herd. Using the herding measure of Lakonishok et al. [1992], we do not find strong imitation behavior, although herding in the market and book-to-market styles are higher. Those pension funds that do not herd or that follow distinctive strategies do not present significant differences in performance with respect to herding funds.     

Cross-country income mobility comparisons under panel attrition: the relevance of weighting schemes

This article aims to present an assessment of the effects of panel attrition on income mobility comparisons for some EU countries by using the European Community Household Panel (ECHP). There are different possibilities of correcting the attrition problem by means of alternative longitudinal weighting schemes. The sensitivity of mobility estimates to these attrition correction procedures is tested in this article. Our results show that ECHP attrition is characterized by a certain degree of selectivity but only affecting some variables and countries. Different probability models corroborate the existence of a certain nonrandom attrition. The model chosen to construct the longitudinal weights to correct attrition offers up rather different results than those obtained when Eurostat's longitudinal weights are used. Although attrition does not seem to have a great effect on aggregated mobility indicators, it does have a decisive effect on decomposition exercises. Our tests reveal certain sensitivity of income mobility measures to the weighting system used.     

Calendar effects in Latin American stock markets

One of the most well-documented empirical regularities in international finance is the presence of calendar effects in historical stock returns. The literature focuses mainly on developed countries, and in general, emerging markets have not received much attention on this issue. We aim to bridge this gap by documenting the existence of significant and robust calendar effects for the main stock markets in Latin America. Upon performing an extreme bounds analysis that adjusts our estimations for model uncertainty, we find a significantly negative Monday effect, generally compensated by a significantly positive Friday effect. These effects are robust to model specification and are stable through time. Even though not as widespread, we also find evidence for a robust turn-of-the-month effect.     

El concepto de poder en la administración

The objective of this work is to explore the concept of power in Administration. What we are interested in studying is the domination exerted from a dominant position in the organization formally established. In this paper we argue that what defines power is the legality, and what defines authority is legitimacy. In the first place we will have a brief discussion of the distinction between legality and legitimacy, in order to distinguish the concept of power from authority. Then, we analyze the concept of power, distinguishing the power that gives the dominant device from the power established in intersubjective relationships, which are defined as relationships of power. Finally, we perform a conceptual approach of the power in Administration and some criticism inherent to this form of domination.     

Does the technological sourcing decision matter? Evidence from Spanish panel data

This paper extends previous analysis of the choice between internal and external R&D to consider the effect of this decision on productivity. Existing empirical research confirms that there is a positive relationship between technological assets and firm performance. However, few works have attempted to identify whether the technological sourcing decision taken by the firm affects productivity. The main finding of this paper is that the technological strategy developed by the firm does affect productivity. This issue is particularly novel as it incorporates the technological sourcing decision taken by the firm. The results we obtain indicate that the technological sourcing decision affects the relationship between technological capital and productivity. Thus, our findings suggest that the decision between internal and external R&D matters.     

More equal but not so fair: an analysis of Brazilian income distribution from 1995 to 2009

This study measures unfair inequality in Brazil between 1995 and 2009. To achieve that, we used the statistical tool developed by Almås et al. (J Public Econ 95:488–499, 2011) and the concept of “responsibility-sensitive” fairness proposed by Bossert (Math Soc Sci 29:1–17, 1995), Konow (J Econ Behav Organ 31(1):13–35, 1996) and Cappelen and Tungodden (Fairness and the proportionality principle, Discussion paper SAM 31/2007. Norwegian School of Economics and Business Administration, 2007). The results indicate that the fairness level in Brazil remained unchanged throughout the analyzed period.
