Macroeconomic theories take polar views on the importance of choice versus chance. At the micro level, it seems realistic to assume that both dimensions play a role for individual employment outcomes, although it might be difficult to separate these two effects. Nevertheless the choice and...

We bridge mathematical number theory with that of optimal control and show that a generalised Fibonacci sequence enters the control function of finite horizon dynamic optimisation problems with one state and one control variable. In particular, we show that the recursive expression describing...

Research on desistance from crime has paid little attention to parenthood as a “turning point”. In this paper, we use Norwegian register data on a population of men and women who had their first child between 1995 and 2001 (131,167 women and 127,415 men). We provide separate estimates for...

In the absence of effective world-wide cooperation to curb global warming, import tariffs on embodied carbon have been proposed as a potential supplement to unilateral emissions pricing. We consider alternative designs for such tariffs, and analyze their effects on global welfare within a...

In spite of increased labour market participation in recent decades, women in Norway still have high part-time rates and seldom work more than their partners. Given that an aging population implies a projected large labour demand in many Western countries, it is important to explore potential...

We identify the causal effect of lump-sum severance payments on non-employment duration in Norway by exploiting a discontinuity in eligibility at age 50. We find that a severance payment worth 1.2 months' earnings at the median lowers the fraction re-employed after a year by six percentage...

While child welfare services of high quality are very important for many children, measuring quality is not a simple task. This paper presents a method for estimating differences in the quality of local child welfare services. We identify the contributions of municipalities to high school...

We construct linked register data on five Norwegian birth cohorts, covering: criminal charges after age 15; family characteristics and history up to age 15; and (for males) IQ test scores. A longitudinal analysis of the risk of initiation into crime in early adulthood suggests an increased risk for...

Relying on a small natural field experiment with random assignment of treatments, I estimate effects of three core elements of most monitoring and enforcement practices: self-reporting, audit frequency and specific deterrence. I find evidence of evasive reporting of violations in self-audits, as...

This paper shows that tradable emissions permits and an emissions tax affect the firms' technology choice differently under uncertainty. A tax encourages the most flexible technology if and only if stochastic costs and the equilibrium permit price have sufficiently strong positive covariance,...
