The Contingent Effect of TMT International Experience on Firms’ Internationalization Speed

Drawing on upper echelons theory, we argue that there will be an inverted U‐curve‐shaped relationship between the top management team's (TMT's) level of international experience and a firm's internationalization speed. Accounting for the role of executive job demands highlighted in upper echelons theory, we further suggest that competitive pressure, product diversification and geographic scope moderate the relationship between TMT international experience and internationalization speed by increasing the demands of TMT managers’ jobs. Using data on the international expansion of 91 retailers between 2003 and 2012, we find empirical support for the inverted U‐curve‐shaped effect of TMT international experience and the moderating role of competitive pressure. We find no moderating effect of product diversification or geographic scope.     

Bullying and ethnic diversity: investigating their relation in the school setting

This particular study investigated school bullying in relation to ethnic diversity in Cyprus. The research involved 469, 8–14 years old pupils of Cypriot origin and 83 pupils of non-Cypriot origin. Two different questionnaires, one for Cypriot and one for non-Cypriot students, were used and data was analyzed using the SPSS statistical package. The findings showed that ethnic diversity seems to be a factor that can precipitate school bullying and victimization in Cypriot primary and secondary schools, that non-Cypriot students feel more victimized than their Cypriot classmates and that they prefer to share their experiences relating to bullying with someone outside of the school. Additionally, the study revealed that verbal and psychological bullying were the most common kinds of bullying that Cypriot and non-Cypriot students faced, and that both groups limit their knowledge of each other to ‘songs, language, food and games’. The study also showed that the teacher’s role in facing and preventing bullying related to ethno-cultural diversity is critical. Finally, citizenship education and the use of mediation techniques are proposed as a means to foster non- Cypriot students’ social inclusion and, thus, prevent their victimization.     

EMPLOYMENT AND OUTPUT EFFECTS OF GOVERNMENT SPENDING: IS GOVERNMENT SIZE IMPORTANT?

The efects of government spending on employment and output may depend on government size and the persistence of spending. The empirical results suggest that permanent (or persistent) changes in government consumption have a greater impact on output and employment than temporary (or cyclical) changes. This implies a negative wealth effect and reduces the stabilization potency of government spending. The findings also support the hypothesis that the output elasticity of government consumption is positive but declines with increases in government size. Using the estimated equations, I calculate the optimal government size for the representative country as around 20 percent of GDP.     

Estimation of a Semiparametric Recursive Bivariate Probit Model with Nonparametric Mixing

We consider an extension of the recursive bivariate probit model for estimating the effect of a binary variable on a binary outcome in the presence of unobserved confounders, nonlinear covariate effects and overdispersion. Specifically, the model consists of a system of two binary outcomes with a binary endogenous regressor which includes smooth functions of covariates, hence allowing for flexible functional dependence of the responses on the continuous regressors, and arbitrary random intercepts to deal with overdispersion arising from correlated observations on clusters or from the omission of non‐confounding covariates. We fit the model by maximizing a penalized likelihood using an Expectation‐Maximisation algorithm. The issues of automatic multiple smoothing parameter selection and inference are also addressed. The empirical properties of the proposed algorithm are examined in a simulation study. The method is then illustrated using data from a survey on health, aging and wealth.
