Over the last thirty years, the effects of indirect taxation changes have been analysed using comparative static general equilibrium models. We use a new method to analyse current changes in Australia's indirect taxes: dynamic computable general equilibrium modelling. Comparative static methods compare the situation in a given year (usually unspecified) with and without a policy change. The dynamic method shows the effects of a policy change through time. Comparative static methods are usually restricted to estimates of long-run changes in allocative efficiency. The dynamic method provides information not only on efficiency but also on adjustment processes, including variations in employment. With our dynamic method, the effects of policy changes are analysed as deviations from explicit forecasts. We find that these forecasts are important for the policy results. For Australia's current set of indirect tax changes, our main conclusions are (i) the short-run employment effects depend critically on the wage response; (ii) merchandise exporters benefit but tourism is harmed; and (iii) the long-run welfare effectsare likely to be negative, reflecting a decline in the terms of trade and increased compliance costs. 相似文献

This paper reviews Labour's record on the NHS since the 1997 general election. The record shows increased financial investment especially since 2002, coupled with a marked centralisation of strategy and management which is proving counter-productive to further modernisation. 相似文献

This paper shows how economic interdependence affects the indexation decisions of atomistic wage setters in an environment in which monetary authorities do not observe stochastic disturbances before making their policy choices. If stochastic disturbances are common across countries, interdependence has no effect on equilibrium indexation choices in identical countries. However, if disturbances are country specific, numerical simulations show that interdependence is likely to reduce equilibrium indexation choices relative to a small open economy. We also show that indexation choices may be either strategic complements or strategic substitutes, but that strategic complementarity becomes more likely as the degree of interdependence rises. 相似文献

A fundamental result of the principal-agent literature is that pay will be linked to performance when it is difficult for the principal to monitor the agent's actions. However, performance pay can lead to adverse incentives. In these models, high-powered incentives encourage workers to neglect some aspects of their job or to sabotage their coworkers' efforts. This paper offers another explanation for the weak link between pay and performance: worker heterogeneity. When workers are heterogeneous and labor contracts are contests, the Nash equilibrium often pools workers. I show that this implies that the link between pay and performance is weaker than would be the case if firms could observe workers' types before contracting and offer each type their respective optimal contests. 相似文献

Profitability of cow-calf production is determined largely by market prices, calf weaning weights, and cow productive life. While producers individually have no effect on prices, weaning weights and productive life have genetic influences and hence can be altered by selection programs implemented by producers. We investigate the impact of a mutation in the leptin gene (exon 2; single nucleotide polymorphism [SNP] 305) on cow-calf profitability. Prior research shows that this mutation has effects on performance and traits of fed cattle and milk production in dairy cows. Using data from a teaching-research herd, we find that it is also associated with calf weaning weights and cow productive life. A bio-economic stochastic simulation demonstrates that the mutation has statistically positive impacts on profits, suggesting that producers can profitably make use of this information. 相似文献

In a previous article the authors provided an introduction to using the internet as a resource for business ethics. In this sequel they look at newsgroups and chatrooms, and conclude by looking at the websites of Shell and a Shell critic on the controversial ethical aspects of its corporate policy and behaviour.
