Price Sensitivity of Demand for Prescription Drugs: Exploiting a Regression Kink Design

This paper investigates price sensitivity of demand for prescription drugs using drug purchase records for at 20% random sample of the Danish population. We identify price responsiveness by exploiting exogenous variation in prices caused by kinked reimbursement schemes and implement a regression kink design. Thus, within a unifying framework we uncover price sensitivity for different subpopulations and types of drugs. The results suggest low average price responsiveness with corresponding price elasticities ranging from -0.08 to -0.25, implying that demand is inelastic. Individuals with lower education and income are, however, more responsive to the price. Also, essential drugs that prevent deterioration in health and prolong life have lower associated average price sensitivity.Prescription drugs; price; reimbursement schemes; regression kink design

The Family Gap in Wages: What Wombmates Reveal

We shed new light on the effects of having children on hourly wages by exploiting access to data on the entire population of employed same-sex twins in Denmark. Our second contribution is the use of administrative data on absenteeism; the amount of hours off due to holidays and sickness. Our results suggest that childbearing reduces female hourly wages but the principal explanation is in fact mothers' higher levels of absence. We find a positive wage premium for fathers.fertility, wages, twins

Is Labour Market Training a Curse for the Unemployed? Evidence from a Social Experiment

In this paper, we investigate the impact of classroom training programmes on individual unemployment rates in Denmark. In 1994 a social experiment was conducted, where unemployed applicants for labour market training were randomised into treatment and control groups. We formulate and estimate experimental impact estimators of the effect of treatment on the treated. The experimental data is polluted by the presence of no-shows and crossovers, which implies that traditional experimental estimators are biased. Therefore we formulate and estimate an endogenous variables model (using the randomisation indicator as a perfect exclusion restriction) and implement various matching estimators. We find – surprisingly – that classroom training significantly increases individual unemployment rates. We discuss some possible reasons for this surprising finding and some related policy issues

ræsonnementer i folkeskolens matematikundervisning – karakterisering, initiering, identificering og vurdering af ræsonnementskompetencen

Med introduktionen af kompetencetænkning i Fælles Mål 2009 fik folkeskolens matematiklærereen ny udfordring i forhold til planlægning, gennemførelse og evaluering af undervisning. Påbaggrund af et udviklingsarbejde beskrives det hvordan udformningen af elevaktiviteter, herunderisær oplægget, har betydning for initiering og udvikling af ræsonnementskompetence og lærerensmulighed for at kunne evaluere kompetencens udvikling. (a) I oplægget skal det tydeliggøres at måleter at gennemføre eksplicitte ræsonnementer, (b) aktiviteten skal være udfordrende i den forstand atden yder faglig modstand, og (c) der kan eventuelt aftales “spilleregler” der forpligter eleverne på atargumentere. Artiklen rummer endvidere en almen diskussion af kompetencebegrebet samt overvejelserom evaluering heraf
