    Abstract: Recent developments in the German demography will give rise to a shortage in skilled workers in the coming decades. The German economy is in need of thousands of engineers already. A solution to this problem might involve a higher degree of integration of female engineers into the workforce. Data from the microcensus 2006, the official representative statistics of the population and the labour market in Germany, confirm the existence of a hidden reserve of female engineers. Ordered response models and seminonparametric estimation methods are used to show that the labour supply in the engineering sector is mainly determined by age. In addition, the labour supply of female engineers depends on how many children they have, on the age of their youngest child, and on their partners' income. Moreover, women care more about their families, rather than focusing on their career.

    Abstract: TNF-alpha inhibitors represent one of the most important areas of biopharmaceuticals by sales, with three blockbusters accounting for 8 % of total pharmaceutical sale in Norway. With use of a unique natural policy experiment in Norway, this paper examines to what extent the identity of the third-party payer affects doctors choice between the three available drugs. We are able to investigate to what extent the price responsiveness of prescription choices is affected when the identity of the third-party payer changes. The three dominating drugs in this market, Enbrel, Remicade, and Humira, are substitutes, but have had different and varying funding schemes - hospitals and the national insurance plan. We find that treatment choices are price responsive, and that the price response increases when the doctor’s affiliated hospital covers the cost instead of a traditional fee-for-service insurance plan.
    Keywords: Pharmaceuticals; discrete choice model; funding schemes

    Abstract: Rapid economic and demographic change in Ireland over the last decade, with associated increases in car dependence and congestion, has focused policy on encouraging more sustainable forms of travel. In this context, knowledge of current travel patterns and their determinants is crucial. In this paper, we extend earlier Irish research to examine the joint decision of car ownership and mode of transport to work. We employ cross-section micro-data from the 2006 Census of Population to estimate discrete choice models of car ownership and commuting mode choice for four subsamples of the Irish population, based on residential location. Empirical results suggest that travel and supply-side characteristics such as travel time, costs, work location and public transport availability, as well as demographic and socio-economic characteristics such as age and household composition have significant effects on these decisions.

    Abstract: In this paper we aim to look into the attributes of Ghanaians’ willingness-to-pay for green products. This would help us to assess whether Ghanaians show a preference towards environmental goods. The methodology employed to address these issues is an ‘experimentally-adapted’ CV survey which involves laboratory experiment conducted among Ghanaian University students. Notwithstanding the limitations arising from the sample used in our experiment (most notably University students do not represent, economically wise, the entire Ghanaian population), we believe that our investigation provides a first answer to such question as Ghanaians consistently show that they are willing to pay an extra premium for green products.
    Keywords: contingent valuation; experiment; incentive-compatible; Ghana; organic products; willingness to pay.
