It is extraordinarily difficult to determine the extent to which the gender wage gap reflects discriminatory behaviors by employers or differences in productive capacities between men and women. We note that where piece-rate work is performed, wages should in principle reflect productivity...

When analyzing panel data using regression models, it is often reasonable to allow for time-varying covariate effects. We propose a novel approach to modelling timevarying coefficients in panel data regressions, which is based on penalized regression techniques. To illustrate the usefulness of...

This paper investigates misspecified estimation and model selection criteria derived from the "Information Criterion (see Akaike (1973))" for qualitative choice models. Four estimators for the "Information Criterion" are derived for general qualitative choice models. Two of these estimators were...

We use administrative data on Swedish lottery players to estimate the causal impact of wealth on players' own health and their children's health and developmental outcomes. Our estimation sample is large, virtually free of attrition, and allows us to control for the factors such as the number of...

I examine if employment protection affects parental childcare. I find that a softer employment protection has a substantial effect on how parents use and divide paid childcare between them. The identification relies on a reform that made it easier for employers in Sweden to dismiss workers in...

The high and rapidly increasing prevalence of mental illnesses underscores the importance of understanding their causal origins. This paper analyzes one factor at a critical stage of human development: exposure to maternal stress from family ruptures during the fetal period. We find that in...

We study the effect of child care costs on the fertility behavior of Swedish women and find that reductions in child care charges influence fertility decisions, even when costs are initially highly subsidized. Exploiting the exogenous variation in child care costs caused by a Swedish child care...

We analyze the evolution of cultural traits when parents purposefully invest resources in order to socialize their children to the cultural traits that maximize child lifetime utility. We assume that children are not passive in their adoption of traits from peers. Instead they are guided by an...

Using cultural transmission, we develop a model that gives some microfoundation to the impact of residential neighborhood on children's educational attainment and then test it using the UK National Child Development Study. We find that, for high-educated parents, the better the quality of the...
