We propose a natural conjugate prior for the instrumental variables regression model. The prior is a natural conjugate one since the marginal prior and posterior of the structural parameter have the same functional expressions which directly reveal the update from prior to posterior. The Jeffreys prior results from a specific setting of the prior parameters and results in a marginal posterior of the structural parameter that has an identical functional form as the sampling density of the limited information maximum likelihood estimator. We construct informative priors for the Angrist–Krueger [1991. Does compulsory school attendance affect schooling and earnings? Quarterly Journal of Economics 106, 979–1014] data and show that the marginal posterior of the return on education in the US coincides with the marginal posterior from the Southern region when we use the Jeffreys prior. This result occurs since the instruments are the strongest in the Southern region and the posterior using the Jeffreys prior, identical to maximum likelihood, focusses on the strongest available instruments. We construct informative priors for the other regions that make their posteriors of the return on education similar to that of the US and the Southern region. These priors show the amount of prior information needed to obtain comparable results for all regions. 相似文献

Seven computerprograms for non-linear regression or curve fitting problems are compared. The comparison of the programs, running in different computing centra, is restricted to the fit performance. Six model functions are fitted according to the least squares criterion to data series, arising from practical work. The special least squares minimization programs turned out to be better suited for these problems than general optimizing programs. 相似文献

This paper deals with the specification of pollution abatement in dynamic computable general equilibrium (CGE) models and analyses the dynamic feedback mechanisms between economy and abatement in the context of environmental policy. A Ramsey-type economic model is presented, in which bottom-up technical and economic information on abatement techniques is integrated in a top-down dynamic CGE context. The practical suitability of the specification is illustrated by an empirical application for climate change and acidification in the Netherlands. The results show that a mixture of some slowdown of economic growth, a substantial restructuring of the economy and implementation of most technical abatement measures is optimal. 相似文献

Recently, applications of cooperative game theory to economic allocation problems have gained popularity. We investigate a
class of cooperative games that generalizes some economic applications with a similar structure. These are the so-called line-graph
games being cooperative TU-games in which the players are linearly ordered. Examples of situations that can be modeled like
this are sequencing situations and water distribution problems. We define four properties with respect to deleting edges that
each selects a unique component efficient solution on the class of line-graph games. We interpret these solutions and properties
in terms of dividend distributions, and apply them to economic situations.

Although overall linkages are steadily increasing in growth processes, em-pirical data supply strong evidence of large intercountry and intertemporal fluctuations of the domestic-to-overall linkages ratio. This paper tries to explain this phenomenon by modelling a producers' behaviour which appears more realistic than that usually assumed in interindustry or computable general equilibrium models. The main novelty of the results is that the same causes that generate interindustry multipliers can also ‘trap’ domestic linkages into reinforcing (‘virtuous’) or weakening (‘vicious’) circles, depending on whether the price competitiveness of domestic activities is above or below a threshold related to the non-price competitiveness of those activities. These results can help to explain the fluctuations of domestic linkages with respect to overall linkages by spatial and temporal shifts of the threshold between the vicious and the virtuous ‘areas’. Moreover, they emphasize the importance of supply policies-mainly R&D policies—because of their ‘pushing down’ effect on this threshold. 相似文献

Decomposing Redistributive Effects of Taxes and Transfers in Australia: Annual and Lifetime Measures
This paper decomposes the redistributive effect on annual and lifetime inquality of a range of taxes and transfers in Australia, using a dynamic cohort lifetime simulation model. The redistributive effect is decomposed into vertical, horizontal and reranking effects. Horizontal inequities in the tax and transfer system are found to be negligible. The extent of reranking is greater in the lifetime than in the annual context and is affected by the equivalence scales used to adjust household incomes. If no adjustment is made to household incomes, reranking is about nine per cent of the reduction in lifetime inequality. However, if each child is counted as equivalent to one-third of an adult, reranking is found to be less than one per cent. 相似文献

Abstract. Economic theories of managing renewable resources, such as fisheries and forestry, traditionally assume that individual harvesters
are perfectly rational and thus able to compute the harvesting strategy that maximizes their discounted profits. The current
paper presents an alternative approach based on bounded rationality and evolutionary mechanisms. It is assumed that individual
harvesters face a choice between two harvesting strategies. The evolution of the distribution of strategies in the population
is modeled through a replicator dynamics equation. The latter captures the idea that strategies yielding above average profits
are demanded more than strategies yielding below average profits, so that the first type ends up accounting for a larger part
in the population. From a mathematical perspective, the combination of resource and evolutionary processes leads to complex
dynamics. The paper presents the existence and stability conditions for each steady-state of the system and analyzes dynamic
paths to the equilibrium. In addition, effects of changes in prices are analyzed. A main result of the paper is that under
certain conditions both strategies can survive in the long-run.
