Unique among developed countries in denying patent protection for pharmaceuticals, Canada modified her laws in 1987 and again in 1993 to meet international standards, thereby permitting her to participate in NAFTA and become a signatory of the TRIPS of the Uruguay Round. Canada's concerns for containing health costs and providing quality health care for all its citizens were important factors in her original position. It was only as a result of international pressure and an alliance between the multinational pharmaceutical firms and the university community in Canada that she offered greater patent protection. The results of these changes had an immediate effect on improving the business environments and significant investments by the multinational pharmaceutical firms have increased substantially since 1987. 相似文献

Trotz weiter gestiegener ?lpreise expandiert die Weltwirtschaft kr?ftig. Davon profitiert auch die deutsche Wirtschaft; sie
befindet sich in einem Aufschwung, zu dem mehr und mehr die Binnennachfrage beitr?gt. Allerdings haben die Zinsen weltweit
merklich angezogen, und angesichts zunehmender inflation?rer Risiken ist eine weitere Straffung der geldpolitischen Zügel
sicher. Wie stark wird die wirtschaftliche Entwicklung dadurch ged?mpft? Wie verkraftet die deutsche Wirtschaft überdies die
deutliche Anhebung der Mehrwertsteuer im n?chsten Jahr?

A natural field experiment is conducted on the determinants of consumer’s willingness to pay for “fair trade” (FT) products. In four treatments, subjects are offered different choices in connection with a coffee purchase, such as buying regular coffee or FT coffee at a premium, regular coffee with or without a premium, or donating directly or not donating. Depending on the treatment, the premium or direct donations are either given to FT or a well-known charity. A large part of the willingness to pay a premium for FT coffee over regular coffee is shown to be not related to the specific attributes of FT coffee but rather caused by the indirect transfer mechanism that FT uses, i.e., selling products at a premium which goes to the cause of FT. 相似文献

Using foreign direct investment as a governance mechanism has a cost side that goes beyond mere production and input costs. The governance costs of foreign operations are often vague and underestimated, and sometimes even ignored by companies entering a foreign market. The effects of these costs have also largely been neglected in former empirical research. This study examines the governance cost effects on foreign subsidiary performance. Using data from a survey of 160 Norwegian multinational companies the study shows that there are significant and negative relationships between bargaining, monitoring, and maladaptation costs and subsidiary performance. Conversely, costs incurred due to bonding activities are positively associated with performance. Overall, this study indicates that governance costs play a significant role in explaining the performance of foreign subsidiaries: close to 40% of the variation in performance can be attributed to such costs. Dealing with such costs is hence of utmost importance for the management of multinational companies. 相似文献

Over the last decade, several authors have questioned thevalidity of the hedonic travel cost model, arguing instead that the random utility model is a superior method forvaluing recreational site attributes. This paper demonstrates that the two methods emanate from a similar utilitytheoretic framework; yet in practice these methods differ in the assumptions made in their application.Constraining the underlying utility functions to be consistent, both models are applied to the valuation ofrecreational site attributes in the Southeastern United States. The way in which each method estimates preferencesfor site attributes is shown to depend critically on the method and the functional form of theunderlying utility function. 相似文献
