  2. On the positive correlation between education and fertility intentions in Europe: Individual- and country-level evidence

    Testa, Maria Rita
    Increasing shares of European women are making large investments in their human capital. Whether and to what extent these investments are in conflict with reproductive behaviour are issues that have repercussions for fertility levels. Using two Eurobarometer survey data (2006 and 2011) on individuals clustered in the 27 EU countries, I investigate the relationship between women's education and lifetime fertility intentions. Results suggest that a positive association between women's level of education and lifetime fertility intentions exists at both the individual and country levels, as well as in a micro-macro integrated framework. The main explanation for these findings - which...

  3. Prospective Ageing and Economic Growth in Europe

    Crespo Cuaresma, Jesus; Lábaj, Martin; Pruzinský, Patrik
    We assess empirically the role played by prospective ageing measures as a predictor of income growth in Europe. We show that prospective ageing measures which move beyond chronological age and incorporate changes in life expectancy are able to explain better the recent long-run growth experience of European economies. The improvement in explanatory power of prospective ageing indicators as compared to standard measures based on chronological age is particularly relevant for long-run economic growth horizons.

  4. A Two Period Model with Portfolio Choice: Understanding Results from Different Solution Methods

    Rabitsch, Katrin; Stepanchuk, Serhiy
    Using a stylized two period model we obtain portfolio solutions from two solution approaches that belong to the class of local approximation methods - the approach of Judd and Guu (2001, hereafter 'JG') and the approach of Devereux and Sutherland (2010, 2011,hereafter 'DS') - and compare them with the true portfolio solution. We parameterize the model to match mean, standard deviation, skewness and kurtosis of return data on aggregate MSCI stock market indices. The optimal equity holdings in the true solution depend on the size of uncertainty, and the precise form of this relationship is determined by the distributional properties of equity returns....

  5. Strategic signaling or emotional sanctioning? An experimental study of ex post communication in a repeated public goods game

    Zylbersztejn, Adam
    Several experimental studies show that ex post communication mitigates opportunistic behavior in social dilemmas. The source of this effect, especially in a repeated interaction, is nonetheless still obscure. This study provides a novel empirical testbed for two channels by which ex post communication may affect behavior in a repeated public goods game. One is related to strategic signaling. The other involves emotions induced by others' expressed disapproval. The presence of ex post communication strongly fosters pro-social behavior. The data do not support the signaling hypothesis, favouring the emotion-based explanation instead. (author's abstract)

  6. An empirical assessment of Fairtrade: A perspective for low-and middle-income countries?

    Nindl, Elisabeth
    This paper presents the first cross-country empirical evidence on the determinants of participation in Fairtrade and the impact of the export of Fairtrade certified products on agricultural growth in low- and middle-income countries. Using the number of certified producer organizations per country in 2006-2010 as a proxy for Fairtrade exports, estimation results indicate a small but significantly positive effect on the growth rate of per capita value added in agriculture that is largest in upper middle income countries. Given the particularly poverty-reducing effect of agricultural growth, we find empirical evidence that Fairtrade certification is indeed able to deliver its core values, but misses to target the very poor....

  7. International Portfolios: A Comparison of Solution Methods

    Rabitsch, Katrin; Stepanchuk, Serhiy; Tsyrennikov, Viktor
    We compare the performance of the perturbation-based (local) portfolio solution method of Devereux and Sutherland (2010a, 2011) with a global solution method. We find that the local method performs very well when the model is designed to capture stylized macroeconomic facts and countries/agents are symmetric, i.e. when the latter have similar size, face similar risks and trade assets with similar risk properties. It performs less satisfactory when the agents engaged in financial trade are asymmetric. The global solution method performs substantially better when the model is parameterized to match the observed equity premium, a key stylized finance fact. (authors' abstract)

  8. Simplifying Process Model Abstraction: Techniques for Generating Model Names

    Leopold, Henrik; Mendling, Jan; Reijers, Hajo A.; La Rosa, Marcello
    The increased adoption of business process management approaches, tools, and practices has led organizations to accumulate large collections of business process models. These collections can easily include from a hundred to a thousand models, especially in the context of multinational corporations or as a result of organizational mergers and acquisitions. A concrete problem is thus how to maintain these large repositories in such a way that their complexity does not hamper their practical usefulness as a means to describe and communicate business operations. This paper proposes a technique to automatically infer suitable names for business process models and fragments thereof. This technique is useful for model...
