We use idiosyncratic variation in gender composition across cohorts within Norwegian lower-secondary schools to analyze the impact of female peers on students' grades and choices of STEM subjects. We find that more female peers in lower secondary increases girls' probability of choosing...

We use idiosyncratic variation in gender composition across cohorts within Norwegian lower-secondary schools to analyze the impact of female peers on students’ grades and choices of typical masculine subjects (STEM subjects). We find that girls’ performance in mathematics and science...

In 1989, an early retirement program (AFP) was introduced in Norway, with an eligibility age gradually decreasing from 66 to 62, and now covering about two thirds of the labour force. To assess the impact on the labour force we estimate a multinomial logit model for transitions between labour...

We model the choice of transportation mode in a simplified Hotelling-like city, with a fixed number of total travellers, fixed road capacity and with no trade-off between when to travel and the time spent in a queue. A person that chooses to take her own car will inflict a congestion cost on all...

We analyze optimal wealth management, within a global setting, where accumulation of GHGs caused by extraction of fossil resources affects the probability distribution for hitting a threshold or tipping point, indicating a climate change. We derive an optimal strategy for overall wealth...

In 1988, an early retirement program (AFP) was introduced in Norway for the 66-years-old. Since then, AFP has gradually been extended and by now it covers workers aged 62-66. In this paper we employ a multinominal logit model to study the transition between states in the labour market. The model...
