Sexual Orientation and Labor Force Participation: Findings from Chile and Uruguay

This is the first study that examines the association between sexual orientation and labor force participation in Chile and Uruguay. Using information on heads of households and their partners from recent census data, it applies a simple econometric methodology to measure the relationship of sexual orientation and labor participation, juxtaposing individuals who are part of straight and same-sex couples, while determining any difference in this association according to gender. The study finds that partnered gay men are up to 5.0 percentage points less likely to participate in the workforce compared to married straight men. In addition, lesbians are up to 32.7 percentage points more likely to participate in the labor force compared to married straight women. Trends between the two countries are similar, but the likelihood of participating in the labor force differs significantly. Conservatism in the cultural context and legal frameworks of each country arises as a possible explanation.     

SAVING AND INVESTMENT: PARADIGMS, PUZZLES, POLICIES

The 1990s have seen a renewed interest in issues of capitalaccumulation and growth. New paradigms for saving, investment,and growth have been advanced to address theoretical and empiricalpuzzles and to guide the design of better policies. This paperprovides a policy-oriented review of recent theoretical andempirical work on the determinants of saving and investmentand on their links to growth. It takes stock of new findingsas well as still unresolved questions and gives particular attentionto empirical regularities and to the policy issues relevantto developing countries.      

Mismatches in the Spanish Labor Market: Education vs. Competence Match

The accuracy of the match between a workers talents, skills, and capabilities and those required by his or her job has seldom been addressed in the empirical literature. However, a number of analyses on the match between workers education levels and those required by jobs have been published over the last 10 years. Obviously, the level of formal education completed by workers is more easily observed than their levels of human capital competences. Indeed, the latter would be rather difficult to observe. Nonetheless, this approximation is not straightforward, since formal education is only a mean for the acquisition of some human capital competences. We cross-examine the education match and the competence match between the supply and the demand of labor in Spain with data from 1998. Our results suggest that both types of matches do differ in their incidence, determinants, and wage consequences.     

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.     

Provider involvement in business service definition: A typology

This paper proposes a typology for provider roles in defining business services. The starting point of the study is the underlying rationale of much of the service purchasing literature that buyers have or can easily access the necessary know-how to procure business services. If this does not hold, the implication is that buying firms would shy away from buying complex services. An alternative perspective recognizes that purchasing business services requires its own set of sourcing capabilities, which may be lacking. Buying firms may have limited know-how in terms of defining and articulating their requirements or not be fully aware of them in the first place. However, the buyer's lack of sourcing capabilities need not be an injunction to internalize the service. In these circumstances, service providers step in, help buying firms specify their requirements and play a key role in defining what is procured and how. We build on this interactive view of service definition to undertake a comparative case analysis of four business service contracting situations arrayed along two dimensions — buyer perceived uncertainty and provider's buyer-specific experience. We conclude that service providers play different roles in each case. These are classified as translating, re-engineering, developing, and fine-tuning roles.     

Semiparametric estimation of the fractional differencing parameter in the UK industrial production index

The order of integration of the industrial production index in the UK is investigated by means of semiparametric techniques in the time and in the frequency domain. Several methods like the RS statistic, along with others proposed by Robinson in a number of articles are applied to various differenced transformations of the log of the series. These methods perform poorly when using the time domain approaches, however, when using the frequency domain, the results are fairly conclusive. Evidence is found of a unit root at the zero frequency in the logged series whether or not the series is monthly seasonally differenced first.     

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.     

Time series analysis of monthly beef cattle prices with nonlinear autoregressive models

This paper analyses the dynamics underlying a time series of the monthly average beef cattle price received by producers in the State of São Paulo (Brazil). The time series under study records monthly prices since 1954. An exploratory analysis suggested that after a period of intense government intervention in the cattle and beef markets, the underlying dynamics seem to be settling to a pattern similar to the one observed prior to that period. In order to try to verify if the underlying dynamics after the interventionist phase are similar to those in former times, a forecasting procedure has been used based on nonlinear autoregressive models. This tye of models were used after the BDS test showed significant results which can be interpreted as nonlinearities in the data. The results discussed in the paper seem to suggest that after a period of intense interventions that lasted over two decades, the current underlying dynamics are close (from a forecasting point of view) to those observed more than thirty years ago.     

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.
