During patent litigation, pay‐for‐delay (P4D) deals involve a payment from a patent holder of a branded drug to a generic drug manufacturer to delay entry and withdraw the patent challenge. In return for staying out of the market, the generic firm receives a payment, and/or an authorized licensed entry at a later date, but before the patent expiration. We examine why such deals are stable when there are multiple potential entrants. We combine the first‐mover advantage for the first generic with the ability of the branded manufacturer to launch an authorized generic (AG) to show when P4D deals are an equilibrium outcome. We further show that limiting a branded firm's ability to launch an AG before entry by a successful challenger will deter such deals. However, removing exclusivity period for the first generic challenger will not.  相似文献

In this progress report, we first indicate the origins and early development of the Marshallian macroeconomic model (MMM) and briefly review some of our past empirical forecasting experiments with the model. Then we present recently developed one-sector, two-sector and n-sector models of an economy that can be employed to explain past experience, predict future outcomes and analyze policy problems. The results of simulation experiments with various versions of the model are provided to illustrate some of its dynamic properties that include “chaotic” features. Last, we present comments on planned future work with the model.  相似文献

A bstract Previous theoretical and empirical research on economic sociology leaves much to be desired in terms of consistently defining the agenda and objectives of the discipline As a result, economic sociology often appears to lack a clearly defined mission and purpose This is epitomized by various failures to establish adequate epistemological relations of the proper realm of economic sociology with those of economics and sociology, and especially with the domain of rational choice theory This failure is compounded by a misplaced distinction between the subject matter of economic sociology and that of sociological economics, or socioeconomics And some recent works in the discipline (including the ambitious Handbook of Economic Sociology ) have not helped to remedy this situation In this paper, we try to address this situation by suggesting some reformulations of the subject matter of economic sociology in relation to those of related disciplines In addition, we attempt to redefine the field of the sociology of the market which is seen as the focal specialty of economic sociology  相似文献

The simulation problem is one of the most commonly used formats in computer-assisted instruction (CAI). In medical education, a patient simulation problem is known as a patient management problem (PMP). A number of computerized PMP systems are currently available. However, to date, there is no record of PMP systems having been developed using artificial intelligence. This is noteworthy since artificial intelligence techniques could help in the generation of more effective and intelligent instructional systems.

This paper analyzes and evaluates existing instructional simulation software in clinical medicine in terms of effective educational design attributes. Components of effective PMP systems thus identified are incorporated into a computerized instructional system which uses artificial intelligence techniques for teaching problem-solving and diagnostic skills to undergraduate medical students.  相似文献

Intention and Stochastic Outcomes: An Experimental study   总被引:1,自引:0,他引:1  
Do people care about intentions – even when good intentions do not produce good results? In our experiments we find that rates of punishment and reward react strongly to intentions (the wage a firm decides to pay) and more modestly to distributional outcomes (the higher or lower wage actually received including the stochastic component). For example, workers who end up receiving medium wages respond much more positively when this resulted from the firm offering a high wage but bad luck lowered the worker's pay than when this resulted from the firm offering a low wage and good luck raised the pay.  相似文献

Law and finance: why does legal origin matter?   总被引:2,自引:0,他引:2  
This paper assesses empirically two theories of why legal origin influences financial development. The political channel stresses that legal traditions differ in the priority they give to the rights of individual investors vis-à-vis the state and this has repercussions for financial development. The adaptability channel holds that legal traditions differ in their ability to adjust to changing commercial circumstances and legal systems that adapt quickly will foster financial development more effectively. We use historical comparisons and cross-country regressions to assess the validity of these two channels. We find that legal origin matters for financial development because legal traditions differ in their ability to adapt efficiently to evolving economic conditions.

Abstract. This paper estimates the impact of interest rate shocks on regional output in Germany over the period from 1970 to 2000. We use a vector autoregression (VAR) model to obtain impulse responses, which reveal differences in the output responses to monetary policy shocks across ten German provinces. Next, we investigate whether these differences can be related to structural features of the regional economies, such as industry mix, firm size, bank size and openness. An additional analysis of the volatility of real GDP growth for the period 1992–2000 includes the Eastern provinces. We also present evidence on the interrelationship between firm size and industry, and compare our measure of firm size with those used in previous studies. We conclude that the differential regional effects of monetary policy are related to industrial composition, but not to firm size or bank size.  相似文献
