In the paper is considered identification of coefficients in equations explaining a continuous variable, say the number of sickness absence days of an individual per year, by cohort, time and age, subject to their definitional identity. Extensions of a linear equation to polynomials, including...

Identification of equations explaining a continuous variable, e.g., the length of sickness absence spells, by age, cohort and time (ACT), subject to their definitional identity is reconsidered. Various extensions of a linear equation to polynomials are explored. If no interactions between the...

Supervisors occupy central roles in production and performance monitoring. We study how heterogeneity in performance evaluations across supervisors affects employee and supervisor careers and firm outcomes using data on the performance system of a Scandinavian service sector firm. We show that...

In this paper we investigate the demand for local public school expenditures in Sweden. By using survey data, a method previously never applied to Swedish data, the paper provides an additional piece of evidence on individual demand for publicly provided local services. Estimating a linear...

A dynamic process underlying firms' discrete financial choices has previously been found, but without controlling for unobserved heterogeneity, this dependence can either be of a true nature or an effect of firm-specific characteristics that we cannot observe. This study extends previous...

A model of occupational choice and human capital investment is developed and tested. The model allows family background to influence occupational choice via access to economic resources, differences in costs of schooling, and ability uncertainty. The model predicts that people are more sensitive...

Using an open-ended contingent valuation survey, we analyze how (i) experience of a power outage due to one of the worst storms ever to hit Sweden and (ii) a cheap talk script affect respondents' WTP to avoid power outages. Experience significantly increases and a cheap talk script decreases the...

The matching method for treatment evaluation does not balance selective unobserved differences between treated and non-treated. We derive a simple correction term if there is an instrument that shifts the treatment probability to zero in specific cases. Policies with eligibility restrictions,...
