An attempt is made in this paper to formulate a satisfactory duality theory of efficient and optimal programs in intertemporal models with irreversible inveatment. The introduction of the constraint that depreciated capital stock cannot be used for present consumption makes the meaningful choice and interpretation of dual variables a more difficult problem, as is pointed out by means of an example. A new definition of a competitive program is introduced, and this is seen to lead to useful characterizations of efficient and optimal programs. 相似文献

Industrialised nations have responded to the recent impact of new technology either by planning within a corporatist framework, or by reacting to changes determined by 'market forces'. Australia is moving from the second to the first strategy because of a combination of political and legal changes, building upon traditional institutions 相似文献

Because of the growth of new technology based economic development policies at the state level in recent years, this research project provides an assessment of the experiences of users of one such program: the technology research center in microelectronics. A survey of a large number of companies gave us results that should be of interest to decision makers in universities, private industry as well as the public sector. Access to students as future employees was seen as a major reason why companies get involved with universities, more so than research enhancement per se. A univerisity's inability to protect what companies see as confidential research is seen as a major disincentive to further university-industry relationships, while most companies did not see federal or state tax incentives as encouraging collaboration. Among companies who had direct experience with state-funded technology center programs, most reacted positively to their experiences. Such collaboration was seen to stimulate related research within many participating companies, while also leading to improvements in the quality of products and production methods. While the majority of companies thought that states should continue to fund technology development programs, particularly at universities, neither universities nor government were seen as important sources of technical knowledge by many companies. A lack of information about state programs was seen among many companies that responded to the survey. 相似文献

Gender, Time Use, and Public Policy over the Life Cycle 总被引:1,自引:0,他引:1
In this paper we compare gender differences in the allocationof time to market work, domestic work, child care, and leisureover the life cycle. Time-use profiles for these activity categoriesare constructed on survey data for three countries: Australia,the UK, and Germany. We discuss the extent to which gender differencesand life-cycle variation in time use can be explained by publicpolicy, focusing on the tax treatment of the female partnerand on access to high-quality, affordable child care. Profilesof time use, earnings, and taxes are compared over the lifecycle defined on age as well as on phases that represent thekey transitions in the life cycle of a typical household. Ourcontention is that, given the decision to have children, life-cycletime use and consumption decisions of households are determinedby them and by public policy. Before children arrive, the adultmembers of the household have high labour supplies and plentyof leisure. The presence of pre-school children, in combinationwith the tax treatment of the second earner's income and thecost of bought-in child care, dramatically change the patternof time use, leading to large falls in female labour supply.We also highlight the fact that, in the three countries we study,female labour supply exhibits a very high degree of heterogeneityafter the arrival of children, and we show that this has importantimplications for public policy.
