A first step when fitting multilevel models to continuous responses is to explore the degree of clustering in the data. Researchers fit variance-component models and then report the proportion of variation in the response that is due to systematic differences between clusters. Equally they report the response correlation between units within a cluster. These statistics are popularly referred to as

Analys av amerikansk utrikespolitik vad gäller såväl isolationism som aktivt deltagande i världspolitiken i ett långt tidsperspektiv men med ett särskilt fokus på utvecklingen från millennieskiftet.

The effect of minimum wages on employment is a matter of debate, and the existing empirical literature contains mixed results. One reason for this is the methodological difficulties involved where changes in minimum wages are endogenous to other important economic changes. To overcome this problem, we examine exogenous changes to local minimum wages in Indonesia between 1989 and 1994. Our natural

When firms meet in multiple markets, they can leverage punishment ability in one market to sustain collusion in another. This is the first paper to test this theory for multiproduct retailers that sell consumer goods online. With data on the universe of consumer goods sold online in Sweden, I estimate that multimarket contact increases prices. To more closely investigate what drives the effect, I em

A negative association between socioeconomic status (SES) and divorce has been established for most Western nations after 1960, yet we know little about this relationship further back in time when divorce was rare. In low divorce contexts, we expect a positive association between SES and divorce because higher social strata are better equipped to overcome barriers to divorce. According to socioeco

Demographic explanations for the rise in household income inequality include increased educational assortative mating (EAM) and changes in the division of paid labour within families. Building on this research, the current study focuses on the connected nature of these two inequality-producing mechanisms, while at the same time bridging the divide with the economic literature on the role of income

This paper investigates the interaction between cultural norms and neighbourhood characteristics. I estimate the effect of cultural gender norms on the gender gap in math, and explore whether this effect is mitigated by municipality gender equality. I use high-quality Swedish administrative data on the results of national standardised math tests. To separate the effect of cultural gender norms fro

Over the past decades, men’s and women’s time use has changed dramatically suggesting a gender revolution across industrialized nations. Women increased their time in paid work and reduced time in unpaid activities. Men increased their time in unpaid work, but not enough to compensate. Thus, women still perform more unpaid work irrespective of context. We investigate developments regarding men’s a
