The challenges of linking survey and administrative data

Combining survey and administrative data is growing in popularity, even though data access is still highly restricted

Steffen Künn

Using administrative records data and survey data to enhance each other offers huge potential for scientific and policy-related research. Two recent changes have expanded the potential for creating such linked data: the improved availability of data sources and progress in data-matching technology. These developments are reflected, among other ways, in the growing number of academic papers in labor economics that use linked survey and administrative data. While the number of studies using linked data is still small, the trend is clearly upward. Slowing the growth, however, are concerns about data security and privacy, which impede data access.

  • Defining informality vs mitigating its negative effects

    More important than defining and measuring informality is focusing on reducing its detrimental consequences

    There are more informal workers than formal workers across the globe, and yet there remains confusion as to what makes workers or firms informal and how to measure the extent of it. Informal work and informal economic activities imply large efficiency and welfare losses, in terms of low productivity, low earnings, sub-standard working conditions, and lack of social insurance coverage. Rather than quibbling over definitions and measures of informality, it is crucial for policymakers to address these correlates of informality in order to mitigate the negative efficiency and welfare effects.
  • The labor market in Australia, 2000–2016

    Sustained economic growth led to reduced unemployment and real earnings growth, but prosperity has not been equally shared

    Garry Barrett, July 2018
    Since 1991, the Australian economy has experienced sustained economic growth. Aided by the commodities boom and strong public finances, the Australian economy negotiated the global financial crisis without falling into recession. Over this period there were important structural changes, with increasing labor force participation among the elderly and the continuing convergence of employment and unemployment patterns for men and women. However, some recent negative trends include a rise in unemployment, especially long-term unemployment, a deteriorating youth labor market, and a stagnant gender earnings gap.
  • The labor market in Sweden since the 1990s

    The Swedish economy continues to have high employment and rapidly rising real wages

    Nils Gottfries, July 2018
    The economic crisis in the early 1990s brought about a dramatic increase in unemployment and a similar decrease in labor force participation. Unemployment declined afterwards, but stabilized at around 6–7%—more than twice as high as before the crisis. Today, the unemployment rate is lower than the EU average, though Sweden no longer stands out in this respect. The 2008 financial crisis had small effects on the Swedish labor market. Employment in industry declined sharply and then remained stagnant, but employment in the service sectors has continued to grow steadily.
  • The labor market in Brazil, 2001–2015

    An ongoing crisis threatens Brazil’s recent increased earnings and its decreased inequality and gender and ethnic gaps

    From 2001 to 2015, Brazil experienced a profound reduction in income inequality. The commodities boom and some institutional changes in the early 2000s kick-started the Brazilian labor market, increasing the quantity of formal jobs and earnings, especially for the poorest workers. Significant increases in average schooling and the real minimum wage helped reduce ethnic, gender, and regional earnings gaps, though all remain rather high. However, since 2014 a major fiscal crisis has negatively affected GDP and the labor market, seriously threatening these achievements.
  • Do social interactions in the classroom improve academic attainment?

    Student sorting into classes complicates policies that utilize peer effects to optimize educational outcomes

    Shqiponja Telhaj, June 2018
    The role of social interactions in modifying individual behavior is central to many fields of social science. In education, one essential aspect is that “good” peers can potentially improve students’ academic achievement, career choices, or labor market outcomes later in life. Indeed, evidence suggests that good peers are important in raising student attainment, both in compulsory schooling and university. Interventions that change the ability group composition in ways that improve student educational outcomes without exacerbating inequality therefore offer a promising basis for education policies.
  • How should job displacement wage losses be insured?

    Wage losses upon re-employment can seriously harm long-tenured displaced workers if they are not properly insured

    Donald O. Parsons, June 2018
    Job displacement represents a serious earnings risk to long-tenured workers through lower re-employment wages, and these losses may persist for many years. Moreover, this risk is often poorly insured, although not for a lack of policy interest. To reduce this risk, most countries mandate scheduled wage insurance (severance pay), and it is voluntarily provided in others. Actual-loss wage insurance is uncommon, although perceived difficulties may be overplayed. Both approaches offer the hope of greater consumption smoothing, with actual-loss plans carrying greater promise.
  • Effects of regulating international trade on firms and workers

    The benefits of trade regulation increase when workers are mobile

    Raymond Robertson, June 2018
    Economists have shown that international trade increases economic growth, with trade liberalization and integration having characterized the last 50 years. While trade can increase national welfare, recent estimates from both developed and developing countries show that labor market adjustment costs matter. Regulating trade, defined as adding or removing tariffs and other trade barriers, is not the best way to help lower-income workers who suffer from trade-induced losses. Policies that reduce adjustment costs may increase aggregate welfare more than regulating trade flows does.
  • Do anti-discrimination policies work?

    A mix of policies could be the solution to reducing discrimination in the labor market

    Marie-Anne Valfort, May 2018
    Discrimination is a complex, multi-factor phenomenon. Evidence shows widespread discrimination on various grounds, including ethnic origin, sexual orientation, gender identity, religion or beliefs, disability, being over 55 years old, or being a woman. Combating discrimination requires combining the strengths of a range of anti-discrimination policies while also addressing their weaknesses. In particular, policymakers should thoroughly address prejudice (taste-based discrimination), stereotypes (statistical discrimination), cognitive biases, and attention-based discrimination.
