Reference Pricing of Pharmaceuticals for Medicare: Evidence from Germany, the Netherlands and New Zealand

This paper describes three prototypical systems of therapeutic reference pricing (RP) for pharmaceuticals -- Germany, the Netherlands, and New Zealand -- and examines their effects on the availability of new drugs, reimbursement levels, manufacturer prices and out-of-pocket surcharges to patients. RP for pharmaceuticals is not simply analogous to a defined contribution approach to subsidizing insurance coverage. Although a major purpose of RP is to stimulate competition, theory suggests that this is unlikely and this is confirmed by the empirical evidence. Other effects of RP differ across countries in predictable ways, reflecting each country's system design and other cost control policies. New Zealand's RP system has reduced reimbursement and limited the availability of new drugs, particularly more expensive drugs. Compared to these three countries, if RP were applied in the US, it would likely have a more negative effect on prices of on-patent products, due to the more competitive US generic market, and a more negative effect on R&D and on the future supply of new drugs, due to the much larger US share of global pharmaceutical sales.

INFORMATION IMPACTS AND DETERMINANTS OF INFORMATION SELECTION: AN EXPERIMENTAL APPROACH

Laboratory experimentation was used to assess the impacts of information disclosure in imperfect markets. A dual oligopoly market structure was designed with contract information disclosed to subjects under three treatments: no, partial, and full disclosure. Regression analysis revealed some increase in selling price with full information disclosure, but no discernable effects on negotiated prices with partial disclosure. Alternative specifications showed large traders earning significantly lower profits, and information on large traders significantly beneficial to both buyers and sellers. Probit analysis of information selection determinants revealed no significant economic content in trader requests for information under partial disclosure.Marketing,

Single Motherhood and (Un)Equal EducationalOpportunities: Evidence for Germany

We examine the effect of single motherhood on children’s secondary school track choice using 12-year-old children drawn from the German Socio-Economic Panel. In line with previous studies for the U.S., the U.K. and Sweden, we find a negative correlation between single motherhood and children’s educational attainment. Looking for alternative explanations for this correlation, we use probit regression models to control for factors related to single motherhood such as higher educational background, lower household income and higher labor supply of the mother. Our evidence suggests that single motherhood reduces school attainment mainly because it is associated with lower resources (household income) available for the child.school choice, educational attainment, binary response model, German Socio-Economic Panel

We find that the four-firm industries form cartels more often than the duopolies because they gain less from a hysteresis effect after cartel disruption

Do Benefit Hikes Damage Job Finding? Evidence from Swedish Unemployment Insurance Reforms

In 2001 and 2002, Sweden introduced several unemployment insurance reforms. A major innovation in the first reform was the introduction of a two-tiered benefit structure for some unemployed individuals. This system involved supplementary compensation during the first 20 weeks of unemployment. The 2002 reform retained the two-tiered benefit structure but involved also substantial benefit hikes for spells exceeding 20 weeks. This paper examines how these reforms affected transitions from unemployment to employment. We take advantage of the fact that the reforms had quasi-experimental features where the “treatments” differed considerably among unemployed individuals. We find that the reforms had strikingly different effects on job finding among men and women. The two reforms in conjunction are estimated to have increased the expected duration of unemployment among men but to have decreased the duration of unemployment among women. The overall effect on the duration of unemployment is not statistically different from zero. However, the reforms reduced job finding among males who remained unemployed for more than 20 weeks.unemployment duration, unemployment benefits
