Return to Education and the Changing Role of Credentials in the Croatian Labor Market

The countries of Central and Eastern Europe experienced a rapid increase of return to education with the advent of the transition. We look at the dynamics of wage premiums in Croatia and estimate how much the return to education has changed between 1996 and 2004 on the basis of labor force survey data. We also extend the paper in order to address additional features of the wage structure, such as non-linearities in the return to education associated with attainment of credentials. We find that contrary to most transition countries, premiums for education in Croatia began to grow only after the mid 1990s. However, by 2004, they reached the levels of premiums found in other transition countries and advanced market economies, thus creating market incentives for investment in education. We also find that major part of this higher rate of return came through higher return to credentials.

Towards a theorisation of diversity. Configurations of person-related differences in the context of youth welfare practices

ABSTRACT

The article proposes a pathway towards a theorisation of diversity. It is argued that diversity can be understood as referring to the complex outcomes of multifaceted processes in which various schemes of classifications are applied to persons and segments of populations. A growing interest in individuals and their qualities, combined with the development of information technologies, has stimulated a proliferation of person-related categories. Diversity offers an analytical lens for studying the relational qualities of various person-related differences, the interaction between categories of different scale and scope and their situational organisation. Thereby, it goes beyond notions of identity, on the one hand, and intersectionality, on the other. In the second part of the article, the outlined framework is applied to the cases of youth welfare practice in Stuttgart and Frankfurt. The focus of the case analysis is migration-related categories and how they relate to larger configurations of person-related differences in the field of youth welfare practice. It is argued that a diversity perspective, as suggested here, allows us to capture an element of opaqueness and ambiguity concerning migration-related differentiations that has implications for the understanding of ongoing debates about discrimination and racialisation.     

Differences in sexual guilt and desire in East asian and euro-canadian men

Differences in sexual desire between individuals of East Asian and European descent are well-documented, with East Asian individuals reporting lower sexual desire. The mechanisms that underlie this disparity have received little empirical attention. Recent research has found that sex guilt, "a generalized expectancy for self-mediated punishment for violating or for anticipating violating standards of proper sexual conduct" (Mosher & Cross, 1971 , p. 27), mediates the relationship between culture and sexual desire in East Asian and Euro-Canadian women. The goal of this study was to explore this role of sex guilt in men. Male Euro-Canadian (n?=?38) and East Asian (n?=?45) university students completed online questionnaires. The East Asian men reported significantly lower sexual desire and significantly higher sex guilt. Sex guilt was a significant mediator of the relationship between ethnicity and sexual desire, as well as a significant mediator between mainstream acculturation and sexual desire. Among the East Asian men, mainstream acculturation was significantly and negatively correlated with sex guilt such that increasing mainstream acculturation was associated with less sex guilt. The diagnostic and clinical implications of the findings are discussed.     

Immigrant life satisfaction in Europe: the role of social and symbolic boundaries

The cross-national investigation of immigrant subjective well-being remains an understudied field, especially with regard to the link between institutional settings and individual outcomes. We approach this gap by investigating the role of policies regulating immigrant integration for life satisfaction. Immigrants’ status and life chances depend on the inclusiveness of integration policies in forms of rights given to immigrants in the receiving country. These policies differentiate immigrants from natives: exclusionary integration policies understood as social boundaries should result in lower levels of well-being. We also consider an alternative policy type (i.e. multicultural policies) as well as symbolic boundaries (i.e. natives’ attitudes towards immigrants). We distinguish between national citizens, EU citizens and third-country nationals (TCNs). Results based on up to five rounds of data from the European Social Survey indicate that in terms of life satisfaction only TCNs profit from inclusive integration policies. Furthermore, while political multiculturalism does not play a role, we find that EU migrants appear more susceptible to the negative impact of natives’ anti-immigrant attitudes. Policy-making is more important for TCNs, while a migrant-friendly opinion climate is more important for EU migrants. These findings are robust to controlling for unobserved time-constant country heterogeneity via country fixed effects.     

Convergence faible sur des espaces topologiques uniformes et suites aléatoires d'éléments aléatoires

Following some results on weak convergence, theorems are given on the selection of sample elements on uniform spaces. Our results are tied in with a theorem of Fernandez (1971, p. 1740).     

Universal codes as a basis for time series testing

We suggest a new approach to hypothesis testing for ergodic and stationary processes. In contrast to standard methods, the suggested approach gives a possibility to make tests, based on any lossless data compression method even if the distribution law of the codeword lengths is not known. We apply this approach to the following four problems: goodness-of-fit testing (or identity testing), testing for independence, testing of serial independence and homogeneity testing and suggest nonparametric statistical tests for these problems. It is important to note that practically used so-called archivers can be used for suggested testing.     

Modelling stochastic volatility using generalized t distribution

In modelling financial return time series and time-varying volatility, the Gaussian and the Student-t distributions are widely used in stochastic volatility (SV) models. However, other distributions such as the Laplace distribution and generalized error distribution (GED) are also common in SV modelling. Therefore, this paper proposes the use of the generalized t (GT) distribution whose special cases are the Gaussian distribution, Student-t distribution, Laplace distribution and GED. Since the GT distribution is a member of the scale mixture of uniform (SMU) family of distribution, we handle the GT distribution via its SMU representation. We show this SMU form can substantially simplify the Gibbs sampler for Bayesian simulation-based computation and can provide a mean of identifying outliers. In an empirical study, we adopt a GT–SV model to fit the daily return of the exchange rate of Australian dollar to three other currencies and use the exchange rate to US dollar as a covariate. Model implementation relies on Bayesian Markov chain Monte Carlo algorithms using the WinBUGS package.     

Estimation and inference for exponential smooth transition nonlinear volatility models

A family of threshold nonlinear generalised autoregressive conditionally heteroscedastic models is considered, that allows smooth transitions between regimes, capturing size asymmetry via an exponential smooth transition function. A Bayesian approach is taken and an efficient adaptive sampling scheme is employed for inference, including a novel extension to a recently proposed prior for the smoothing parameter that solves a likelihood identification problem. A simulation study illustrates that the sampling scheme performs well, with the chosen prior kept close to uninformative, while successfully ensuring identification of model parameters and accurate inference for the smoothing parameter. An empirical study confirms the potential suitability of the model, highlighting the presence of both mean and volatility (size) asymmetry; while the model is favoured over modern, popular model competitors, including those with sign asymmetry, via the deviance information criterion.
