We examine the long‐run GDP impacts of changes in total government expenditure and in the shares of different spending categories for a sample of OECD countries since the 1970s, taking account of methods of financing expenditure changes and possible endogenous relationships. We provide more systematic empirical evidence than available hitherto for OECD countries, obtaining strong evidence that reallocating total spending towards infrastructure and education is positive for long‐run output levels. Reallocating spending towards social welfare (and away from all other expenditure categories pro‐rata) may be associated with modest negative effects on output in the long run. 相似文献

This paper shows that the adoption of flexible manufacturing techniques by firms leads to a tougher price regime. However, consumers may not benefit since the tougher regime deters entry. Flexible manufacturing's ability to deter entry is moderated by two factors: non-prohibitive costs of re-anchoring flexible manufacturing processes and the possibility that entrants choose to produce niche products using designated technologies rather than adopt flexible manufacturing. Market preemption that deters entry will be characterized by excessive product variety. Alternatively, flexible manufacturers may prefer to accommodate entry by small-scale, niche firms. Moreover, ownership matters in determining equilibrium product configurations. 相似文献

This paper modifies and interprets Data Envelopment Analysis (DEA) using a linear economic model. This approach is similar to the cone input/output and assurance region approaches to DEA, but it is implemented so that the multipliers are measured in the same units across all linear optimization problems. This approach allows one to interpret alternatives as profit maximizing organizations and the DEA multipliers as prices that are comparable across the alternatives. This is a useful extension of the assurance region concept, but more important, is that our approach enhances communication with decision-makers. The improved communication is illustrated by applying the model to the siting of a long-term health care facility. This application is interesting because the multiplier bounds make practical sense, and because the problem has dimensions that sometimes lead to interpretation problems with the traditional DEA model. For example, the site characteristics do not result from coordinated decisions, some sites exhibit zero values for some variables, and the problem has many variables compared with the number of potential sites. Problems with these dimensions have, at times, been deemed unsuitable for DEA, but they are handled without problem by the linear economic model. 相似文献

The results of two recent national surveys of RNs that were conducted at a time when the nursing shortage in the U.S. was in full force (2002) and 2 years later (2004) were compared. The findings provide a mixed assessment: on the one hand, there is evidence that the shortage has eased since 2002 and that there have been notable improvements in the lives of nurses; on the other hand, the shortage has had a negative impact on hospitals and nurses, and longstanding problems associated with the workplace environment remain. 相似文献

Evolutionary game theory has largely focused on finite games. Dynamic stability is harder to attain in infinite strategy spaces; Bomze [Bomze, I., 1990. Dynamical aspects of evolutionary stability. Monatsh. Math. 110, 189–206] and Oechssler and Riedel [Oechssler, J., Riedel, F., 2001. Evolutionary dynamics on infinite strategy spaces. Econ. Theory 17, 141–162] provide conditions for the stability of rest points under the replicator dynamics. Here, conditions are given for the stability of sets of strategies under this process. 相似文献
