Roma integration in European labor markets 

Nuclei of evidence tell a grim story, but a veil of ignorance impedes policy efforts

Martin Kahanec

The Roma are the largest ethnic minority in Europe—as well as one of the most disadvantaged. A triple vicious circle is at play: Substandard socio-economic outcomes reinforce each other; they fuel negative attitudes and perceptions, leading to ill-chosen policies; and segmentation is perpetuated through (statistical) discrimination. A severe lack of data precludes progress. However, existing bits of evidence point to virtuous ways out.

  • Parental leave and maternal labor supply Updated

    Parental leave increases the family–work balance, but prolonged leave may have negative impacts on mothers’ careers

    Astrid Kunze , June 2022
    Numerous studies have investigated whether the provision and generosity of parental leave affects the employment and career prospects of women. Parental leave systems typically provide either short unpaid leave mandated by the firm, as in the US, or more generous and universal leave mandated by the government, as in Canada and several European countries. Key economic policy questions include whether, at the macro level, female employment rates have increased due to parental leave policies; and, at the micro level, whether the probability of returning to work and career prospects have increased for mothers after childbirth.
  • Is the post-communist transition over?

    Support for economic liberalization reforms is essential, but it grows stronger only where societies experience the effects of reversing these reforms

    An extensive program of economic liberalization reforms, even when it generates positive outcomes, does not automatically generate support for further reforms. Societies respond with strong support only after experiencing the effects of reversing these reforms (i.e. corruption, inequality of opportunity). This point is illustrated through the example of the post-communist transformation in Eastern Europe and Central Asia—arguably a context where the end point of reforms was never clearly defined, and even successful reforms are now associated with a degree of reform suspicion.
  • Should unemployment insurance cover partial unemployment? Updated

    Time-limited benefits may yield significant welfare gains and help underemployed part-time workers move to full-time employment

    Susanne Ek Spector , June 2022
    A considerable share of the labor force consists of underemployed part-time workers: employed workers who, for various reasons, are unable to work as much as they would like to. Offering unemployment benefits to part-time unemployed workers is controversial. On the one hand, such benefits can strengthen incentives to take a part-time job rather than remain fully unemployed, thus raising the probability of obtaining at least some employment. On the other hand, these benefits weaken incentives for part-time workers to look for full-time employment. It is also difficult to distinguish people who work part-time by choice from those who do so involuntarily.
  • Determinants of inequality in transition countries

    Market changes and limited redistribution contributed to high income and wealth inequality growth in Eastern Europe

    High levels of economic inequality may lead to lower economic growth and can have negative social and political impacts. Recent empirical research shows that income and wealth inequalities in Eastern Europe since the fall of socialism increased significantly more than previously suggested. Currently, the average Gini index (a common measure) of inequality in Eastern Europe is about 3 percentage points higher than in the rest of Europe. This rise in inequality was initially driven by privatization, liberalization, and deregulation reforms, and, more recently, has been amplified by technological change and globalization coupled with relatively ungenerous income and wealth redistribution policies.
