We consider a two-period model. In the first period, individuals consume two goods: one is sinful and the other is not. The sin good brings pleasure but has a detrimental effect on second period health and individuals tend to underestimate this effect. In the second period, individuals can...

Firms may underinvest in local environmental protection even from the private viewpoint of its owners and employees, but works councils may help mitigate this problem. We show that increases in environmental investments when councils are present could be employee-led, firm-led, or jointly-led....

We investigate the effect of competition on quality in regulated markets (e.g., health care, higher education, public utilities), using a Hotelling framework, in the presence of sluggish demand. We take a differential-game approach, and derive the open-loop solution (providers choose the optimal...

Nationwide health interventions are difficult to evaluate as contemporaneous control groups do not exist and before-after approaches are usually infeasible. We propose an alternative semi-parametric estimator that is based on the assumption that the intervention has no direct effect on the...

This paper explores different empirical strategies to examine the effect of cost sharing for prescription drugs in some dimensions of medication-related quality, namely the probability of inappropriate prescription drug use among United States seniors. Using data from 1996 to 2005, we explore...

We set up a model of GP referral for the Norwegian health care system, where a GP receives capitation payment based on the number of patients in his practice, as well as fee-for-service reimbursements....

After 16 years of exemptions from the ban on indoor smoking in other places of work, Norway became the second country after Ireland to implement a smoke-free regime in pubs and restaurants. This paper evaluates the economic impact on the hospitality sector in a northern region with a cold...

We study Body Mass Index (BMI) changes among immigrants from Iran, Pakistan, Sri Lanka, Turkey, and Vietnam relative to native Norwegians in Oslo. We test a symmetric convergence hypothesis: irrespective of whether an immigrant’s initial BMI is lower or higher than a native Norwegian,...

We study whether the information patients have about physician quality when they choose a physician, influences their probability of switching physicians. We also study whether a physician with unfavorable characteristics, as perceived by patients (ex post), can compensate for patient switching...
