Importation of drugs into the US may soon become legal. Since prices of drugs are lower in most other countries than they are in the US, importation would result in a decline in US drug prices. The purpose of this paper is to assess the consequences of importation for new drug development. First, the author presents a simple theoretical model of drug development which suggests that the elasticity of innovation with respect to the expected price of drugs should be at least as great as the elasticity of innovation with respect to expected market size (disease incidence). Then, the cross-sectional relationship between pharmaceutical innovation and market size among a set of diseases (different types of cancer) exhibiting substantial exogenous variation in expected market size is examined. Two different measures of pharmaceutical innovation are analysed: the number of distinct chemotherapy regimens for treating a cancer site and the number of articles published in scientific journals pertaining to drug therapy for that cancer site. Both analyses indicate that the amount of pharmaceutical innovation increases with disease incidence. The elasticity of the number of chemotherapy regimens with respect to the number of cases is 0.53. The elasticity of MEDLINE drug cites with respect to cancer incidence throughout the world is 0.60. In the long run, a 10% decline in drug prices would therefore be likely to cause at least a 5–6% decline in pharmaceutical innovation. Evidence suggests that pharmaceutical industry employment would also decline (by at least 3.5–4%) in response to an exogenous 10% decline in drug prices. 相似文献

Ireland has been the economic success story of the 1990s. Growth in GNP and in employment has far exceeded those seen elsewhere. We ask first whether this is simply a delayed catching-up process. Even if this turns out to be so, the question remains as to what the key differences in policy were between the unsuccessful phase, from 1950 to 1988, and the phenomenally successful phase since then. We present a brief overview of the key differences in terms familiar from conventional growth theory, and go on to look more carefully at the constellation of factors explaining the precise timing of the turnaround in economic fortunes. 相似文献

Conclusion As we have shown, the validity of various definitions of money cannot be ascertained by means of a statistical correlation
with national income. A valid definition can be established by following the essentialist approach—that is, by focusing on
the distinguishing characteristics of an entity. Contrary to mainstream thinking, we have shown that the money supply definition
remains intact, notwithstanding the deregulation of financial markets and the introduction of electronic means of payments. 相似文献

The regulation of parallel trade is a fiercely debated issue in the global trading system. This paper investigates the welfare effects of parallel trade freedom for different levels of trade costs and market size. It is found that parallel trade freedom has a positive effect on global welfare if countries are sufficiently heterogeneous in terms of market size and trade costs are sufficiently low. Contrary to intuition, this result even holds in a situation where parallel trade freedom implies the closure of the smaller market. If, however, countries are virtually homogenous in terms of market size, parallel trade freedom may be detrimental to global welfare for specific levels of trade costs. 相似文献

An assessment of market-based approaches to providing ecosystem services on agricultural lands 总被引:5,自引:0,他引:5
Market-based approaches are increasingly being advocated as tools for achieving the conservation of ecosystem services. We examine the reasons why markets so far appear to have failed to provide an efficient allocation of many ecosystem services, and identify the conditions under which markets deliver efficient resource allocation. We discuss different forms of market-based approaches to ecosystem services and identify the characteristics of services that make them better suited to one or another of these approaches. We find that lack of low-cost measurability and valuation currently precludes efficient allocation of many ecosystem services through market-based approaches. Still, some forms of market-based approaches hold promise for cost-effectively managing some ecosystem services provided by and to agricultural lands. In many cases some form of well-designed government involvement will be required to seek outcomes that protect the public interest. 相似文献

This paper investigates the relationship between federal election outcomes and expected returns and volatilities in the Canadian money, bond, equity and currency markets from 1951 to 2006. There is little evidence that investment opportunities are different in minority versus majority parliaments and only money market returns differ in Conservative versus Liberal governments. The equity market performs better in the late part of the electoral cycle than in the first two years. Furthermore, the Canadian equity investment opportunities are better in Democratic versus Republican administrations and in the late versus early parts of the presidential electoral cycle. The Canadian dollar is also affected by American election outcomes. No apparent variation in risk or expected state of the economy accounts for the differences in returns. 相似文献

In rational, efficiently functioning and complete markets, returnson derivative and underlying securities should be perfectlycontemporaneously correlated. Due to market imperfections, oneof these markets may reflect information faster. The use ofhigh-frequency data and the choice for a small unit time intervalto measure these lead-lag relations comes at the cost of someor many missing observations, causing traditional estimatorsto either under- or overestimate covariances and correlations.We use a new estimator to estimate lead-lag relationships betweenthe cash AEX index, options and futures. We find that futuresreturns lead both options and cash index returns by approximately10 minutes. The relationship between options and the cash marketis not completely unidirectional.

Ethical decision theory may not be sufficiently well developed to furnish reliable guidelines to people involved in complex decision making that involves conflict between ethical considerations and business imperatives such as making a profit. In conditions of ethical uncertainty hindsight bias may occur, and this study reports on an exploration of hindsight bias effects among participants in continuing education in business programmes. Perceptions of business ethics were found to differ among groups within the sample depending on what they thought had been the outcome of the ethical decision concerned. 相似文献
