The relation between competition and innovation – Why is it such a mess?
No full textUsing a general two-stage framework, this paper gives sufficient conditions for increasing competition to have negative or positive effects on R&D-investment, respectively. Both possibilities arise in plausible situations, even if one uses relatively narrow definitions of increasing competition. The paper also shows that competition is more likely to increase the investments of leaders than those of laggards. When R&D-spillovers are strong, competition is less likely to increase investments. The paper also identifies conditions under which low initial levels of competition make a positive effects of competition on investment more likely. Extending the basic framework, the paper shows that separation of ownership and control, endogenous entry and cumulative investments make positive effects of competition on investment more likely. Imperfect upstream competition weakens the effects of competition on investment.competition, investment, cost reduction
Physician dispensing and the choice between generic and brand-name drugs – Do margins affect choice?
No full textMany politicians blame physician dispensing (PD) to increase health care expenditure and to undermine independence of drug prescription and income leading to a suboptimal medication. Therefore, PD is not allowed in most OECD countries. In Switzerland, PD is allowed in some regions depending on the density of pharmacies. This enables to investigate the difference in prescribing behavior between physician which gain income from prescribing a specific drug and their colleagues which prescribe the drug but do not sell it. Because the considered drugs are bioequivalent we focus on the economic consequence of PD. We analyze the prescribing behavior of Swiss physicians using cross-sectional data between 2005 and 2007 for three important agents. The results support our hypothesis that dispensing physicians have a higher probability of prescribing the drug with the (most likely) higher margin compared to non-dispensing physicians. Further, generic drugs are prescribed more often to patients with higher cost-sharing while patients' cost-sharing is less influential with PD. High-income patients face a much higher probability to receive the brand-name drug due to their lower marginal utility of income. Today's administered reimbursement prices for generics seem to be high enough to gain physicians for prescribing generics because of their high margins.Physician dispensing, prescribing behavior, generics, brand-name drugs
Simulating WTP Values from Random-Coefficient Models
No full textDiscrete Choice Experiments (DCEs) designed to estimate willingness-to-pay (WTP) values are very popular in health economics. With increased computation power and advanced simulation techniques, random-coefficient models have gained an increasing importance in applied work as they allow for taste heterogeneity. This paper discusses the parametrical derivation of WTP values from estimated random-coefficient models and shows how these values can be simulated in cases where they do not have a known distribution.willingness-to-pay, discrete choice, simulation, random-coe±cient models
Lobbying and the Power of Multinational Firms
No full textAre national or multinational firms better lobbyists? This paper analyzes the extent of national environmental regulation when policy is determined in a lobbying game between a government and firm. We compare the resulting regulation levels for national and multinational firms. We identify three countervailing forces, the easier-to-shut-down effect, the easier-to-curb-exports effect and the multiple-plant effect. The interplay of these three forces determines whether national or multinational firms produce more, depending on such parameters as the potential environmental damages, transportation costs and the in uence of the firm. We also show that welfare levels are higher with multinational firms than with national firms when there is no lobbying, but that lobbying can reverse the welfare ordering.Multinational enterprises, regulation, policy formation, lobbying, interest groups, foreign direct investment
Spurious correlation in estimation of the health production function: A note
No full textIn this paper, we address the issue of spurious correlation in the production of health in a systematic way. Spurious correlation entails the risk of linking health status to medical (and nonmedical) inputs when no links exist. This note first presents the bounds testing procedure as a method to detect and avoid spurious correlation. It then applies it to a recent contribution by Lichtenberg (2004), which relates longevity in the United States to pharmaceutical innovation and public health care expenditure. The results of the bounds testing procedure show longevity to be linearly related to these two factors. Therefore, the estimates reported by Lichtenberg (2004) cannot be said to be result of spurious correlation, to the contrary, they very likely reflect an effective relationship, at least for the United States.Health; Life expectancy, Innovation, Pharmaceuticals, Health care expenditure, Cointegration
Is there a U-shaped Relation between Competition and Investment?
No full textWe argue that, in a simple setting, the relation between the intensity of competition and cost-reducing investment is U-shaped. We consider a two-stage game with cost-reducing investments followed by a linear differentiated Cournot duopoly. We first show that, except for firms that are much less efficient than the competitor, investment in the subgame-perfect equilibrium is minimal for intermediate levels of competition, which is inversely parameterized by the extent of product differentiation. An extensive set of laboratory experiments also provides support for the U-shape, both for symmetric firms and for leaders. Also consistent with predictions, the relation is negative for firms that are lagging behind.Investment, intensity of competition, experiment
Between Agora and Shopping Mall
No full textAdvertisements provide consumers with knowledge about private products, whereas political information is required to provide voters with knowledge of public issues. Modern information technologies and globalisation are increasing the exposure of individuals to information. Goods advertising is competing with political information for people's attention. This paper presents a politico-economic equilibrium model in which the tension between private and public agendas can be analysed. It is shown that in an information-rich society, international goods market integration tends to reduce the quality of public policy. Complementing economic integration with political integration can increase the gains from globalisation, though not in all cases.Globalisation, agenda-setting, information-rich societies, scarcity of attention, advertising
Paulo Freire's pedagogy of love
No full textProblem: Throughout his writings, Paulo Freire asserted that education was an act of love, that educators must risk acts of love, and that education should aim at establishing a world where it would be easier to love. But, Freire neither defined love nor explained how education constitutes an act of love. To date, the centrality of love in Freire's thought has been ignored. Defining and interpreting Freire's concept of love constitutes a problem in the philosophy of education. Research Questions: The following interrelated questions will help uncover and clarify this theme in Freire's writings and place love in education in its proper philosophical context. 1) What is Freire’s theory of love as presented in Education as the Practice of Freedom and Pedagogy of the Oppressed? 2) What literature on love can help us understand his theory? and 3) How does his theory of love guide his educational theory? Method: Taking Freire's writings as his effort to create a coherent pedagogy of the oppressed that both requires love and fosters it, a rhetorical analysis of his writings should yield an educational theory that encompasses a theory of love; comparison with recent philosophical ideals regarding love should give pointed definition to Freire's ideals. Significance: This study will provide a new perspective on Freire's work and its place in educational philosophy. It aims at restoring the primacy of love in Freire's pedagogy of the oppressed and achieving an understanding of what love means in Freire's thought and practice.Ed.D.Includes bibliographical references (p. 86-88)Includes abstractGraduate Program in Social and Philosophical Foundationsby Edward Michael Schode
