  1. Age-Specific Education Inequality, Education Mobility and Income Growth

    Crespo Cuaresma, Jesus; K.C., Samir; Sauer, Petra
    We construct a new dataset of inequality in educational attainment by age and sex at the global level. The comparison of education inequality measures across age groups allows us to assess the effect of inter-generational education attainment trends on economic growth. Our results indicate that countries which are able to reduce the inequality of educational attainment of young cohorts over time tend to have higher growth rates of income per capita. This effect is additional to that implied by the accumulation of human capital and implies that policies aiming at providing broad-based access to schooling have returns in terms of economic growth...

  2. On the Determinants of Global Bilateral Migration Flows

    Crespo Cuaresma, Jesus; Moser, Mathias; Raggl, Anna
    We present a method aimed at estimating global bilateral migration flows and assessing their determinants. We employ that fact that available net migration figures for a country are (nonlinear) aggregates of migration flows from and to all other countries of the world in order to construct a statistical model that links the determinants of (unobserved) migration ows to total net migration. Using simple specifications based on the gravity model for international migration, we find that migration flows can be explained by standard gravity model variables such as GDP differences, distance or bilateral population. The usefulness of such models is exemplified...

  3. Ageing, productivity and wages in Austria

    Mahlberg, Bernhard; Freund, Inga; Crespo Cuaresma, Jesus; Prskawetz, Alexia
    Current demographic developments in industrialized countries and their consequences for workforce ageing challenge the sustainability of intergenerational transfers and economic growth. A shrinking share of the young workforce will have to support a growing share of elderly, non-working people. Therefore, the productivity of the workforce is central to a sustainable economic future. Using a new matched employeremployee panel dataset for Austrian firms for the period 2002-2005, we study the relationship between the age structure of employees, labour productivity and wages. These data allow us to account, simultaneously, for both socio-demographic characteristics of employees and firm heterogeneity, in order to explain...

  4. Revisiting the Effects of IMF Programs on Poverty and Inequality

    Oberdabernig, Doris Anita
    Investigating how lending programs of the International Monetary Fund (IMF) affect poverty and inequality, we explicitly address model uncertainty. We control for endogenous selection into IMF programs using data on 86 low- and middle income countries for the 1982-2009 period and analyze program effects on various poverty and inequality measures. The results rely on averaging over 90 specifications of treatment effect models and indicate adverse short-run effects of IMF agreements on poverty and inequality for the whole sample, while for a 2000-2009 subsample the results are reversed. There is evidence that significant short-run effects might disappear in the long-run. (author's abstract)

  5. Model trees with topic model preprocessing: an approach for data journalism illustrated with the WikiLeaks Afghanistan war logs

    Rusch, Thomas; Hofmarcher, Paul; Hatzinger, Reinhold; Hornik, Kurt
    The WikiLeaks Afghanistan war logs contain nearly 77,000 reports of incidents in the US-led Afghanistan war, covering the period from January 2004 to December 2009. The recent growth of data on complex social systems and the potential to derive stories from them has shifted the focus of journalistic and scientific attention increasingly toward data-driven journalism and computational social science. In this paper we advocate the usage of modern statistical methods for problems of data journalism and beyond, which may help journalistic and scientific work and lead to additional insight. Using the WikiLeaks Afghanistan war logs for illustration, we present an approach that builds intelligible statistical models for interpretable segments...

  7. Theoretical vs. Empirical Power Indices: Do Preferences Matter?

    Badinger, Harald; Mühlböck, Monika; Nindl, Elisabeth; Reuter, Wolf Heinrich
    This paper considers empirically whether preference-based (empirical) power indices differ significantly from their preference-free (theoretical) counterparts. Drawing on the to date most comprehensive sample of EU Council votes (1993-2011), we use item-response models to estimate the EU27 member states' preferences (ideal points) in a one-dimensional policy space. Their posterior distributions are then used for the calculation of empirical versions of the Banzhaf, the Shapley-Shubik, and other power indices, invoking the concepts of connected coalitions and bloc voting. Our ideal point estimates point to significant differences in member states' preferences, which often translate into significant differences of empirical (versus theoretical) power...
