We study the optimal investment and consumption problem of a CRRA investor when the drift and volatility of the stock are driven by a correlated factor. The myopic and non‐myopic components of the optimal portfolio process are characterised in terms of the market price of traded and non‐traded risk of the minimax martingale measure. We find that the optimal policies depend crucially on the nature of the agent, aggressive versus conservative, and the market incompleteness, improving versus deteriorating investment opportunities. Furthermore, we show that the original problem cannot be decomposed into a pure consumption and a pure terminal wealth problem, unless the market is complete. 相似文献

This paper studies financial intermediation in a general equilibriumoverlapping generations model. Indivisible investment projects combine withinformational imperfections to create a (hidden action) moral hazard problemand introduce a role for third-party monitoring. Agency costs at theintermediary level are also considered. Under some conditions, monitors canbe viewed as banks facing a non-trivial portfolio diversification problem.Equilibria are derived in which a large nationwide bank coexists with anumber of community-regional banks, a structure of strong empiricalrelevance. Policies such as a mandatory reserve requirement are shown tohave substantial effects on the levels of investment in the economy. 相似文献

The study finds that relative to others, firms pursuing the Prospector-like strategy (high innovation) have lower financial results uncertainty, a more long-term orientation for decision making, and more decentralized control. As well, the tightness of budgetary control is found to be negatively correlated with financial results uncertainty. Thus, we are able to reproduce in our study the result that Prospector type firms have tighter budgetary control, which many have found puzzling previously, and point to the relation between strategy and financial results uncertainty as an explanation for the result.Based on a sample of large firms in Singapore, the study also finds the impact of the 1997–1998 Asian crisis is correlated with the intensity with which the Prospector-like strategy was pursued. 相似文献

The status quo for school science and technology is unacceptable. While the former often is required for admission to university engineering,
as well as to science programmes, the latter is deemed most appropriate for less able, concrete thinkers. This situation persists,
despite the fact school science tends to generate large groups of citizens who are relatively scientifically and technologically
illiterate, largely as a result of its preoccupation with identifying and training potential scientists and engineers. This
practice is tyrannical. It must be abandoned forthwith. A realistic alternative is a combined technology and science programme
– perhaps called 'technoscience' education – that would treat science and technology as equals. Such courses may, as well,
be more democratic in the sense that technological problem solving often is more natural to everyday situations that everyone
may find useful, not just future scientists or engineers. A framework for combined technology and science courses is described
and defended here. Originally developed through collaborative action research amongst practising teachers of science, the
approach appears to be feasible, under certain – perhaps ideal – conditions. A number of changes to science and technology
education may be necessary for broader implementation, not the least of which is a general retrenchment in expectations for
pre-determined learning, along with adjustments to teacher education. Nevertheless, the approach is recommended because of
its emphasis on: personalization, inclusion, problematization, explicitness, apprenticeship, authenticity, contextualization
and freedom.

The Private Finance Initiative (PFI) was launched by the United Kingdom Government in 1992 in order to encourage the private sector in the UK to become more involved in public sector development projects. A key theme of the initiative was that the public should receive 'value for money'. This article investigates the accounting issue as to whether or not the private or the public sector should record any property related to PFI projects on balance sheet. It argues that although both HM Treasury and the Accounting Standards Board (ASB) might agree on the accounting principles, the practical impact is that in order for related properties to stay off the public sector's balance sheet, substantial risk needs to be transferred to the private sector. As a consequence of this, the objective of providing value for money to the public may not be achieved. 相似文献

Disentangling the Dividend Information in Splits: A Decomposition Using Conditional Event-Study Methods 总被引:3,自引:0,他引:3
While folklore in finance holds that split valuation effectsare due to dividend increases associated with splits, littleis known about magnitudes of dividend and nondividend componentsof split announcement effects. We find that splits and dividendsare indeed informational substitutes, a notion we characterizemore precisely, but a significant portion of split valuationeffects, 46% according to our estimates, cannot be attributedto dividend information in splits. Our techniques extend theliterature on conditional event-study methods and we illustratetheir practical value in testing hypotheses and analyzing datanot amenable to analysis by standard procedures. 相似文献

The new urbanism argues that land-use planning should be used to create higher-density development and to promote alternatives to the use of personal automobiles for transportation. The concerns of the new urbanist movement are shown to be misplaced, and the goals of the new urbanism are shown to be in conflict with market incentives, making them difficult to implement in any event. A better policy for more efficient land use would be for governments to plan more effectively for their own infrastructure development while allowing the development of privately-owned land to be guided by market forces. 相似文献

Water and Economic Growth 总被引:1,自引:0,他引:1
Edward B. Barbier 《The Economic record》2004,80(248):1-16
Several hydrological studies forecast a global problem of water scarcity. This raises the question as to whether increasing water scarcity may impose constraints on the growth of countries. The influence of water utilisation on economic growth is depicted through a growth model that includes this congestible nonexcludable good as a productive input for private producers. Growth is negatively affected by the government's appropriation of output to supply water but positively influenced by the contribution of increased water use to capital productivity, leading to an inverted-U relationship between economic growth and the rate of water utilisation. Cross-country estimations confirm this relationship and suggest that for most economies current rates of fresh water utilisation are not yet constraining growth. However, for a handful of countries, moderate or extreme water scarcity may adversely affect economic growth. Nevertheless, even for water-scarce countries, there appears to be little evidence that there are severe diminishing returns to allocating more output to provide water, thus resulting in falling income per capita. These results suggest caution over the claims of some hydrological-based studies of a widespread global 'water crisis'. 相似文献

The relationship between the relative risk aversion measure for the utility function for consumption and that for the value function for wealth is a derived relationship whose properties depend on how consumption and wealth are defined and measured. This fact together with information concerning estimates for these two relative risk aversion measures is used to give another perspective on the equity premium puzzle, and to explain why it is that the habit formation utility function is effective in eliminating that puzzle. A time separable utility function that can serve as an alternative to the assumption of habit formation is also presented. 相似文献

This paper develops an international version of the consumption-based capital asset pricing (CCAPM), which we refer to as “catching up with the Americans.” Previous CCAPM research develops the concept of “catching up with the Joneses,” where a representative economic agent exhibits higher marginal utility of consumption as a result of higher past per capita consumption in his own country. Catching up with the Americans, on the other hand, is an international habit-preference hypothesis. It extends the idea of catching up with the Joneses by stating that consumers of non-U.S. countries gain higher marginal utility of consumption as a result of higher past American consumption growth. Contrary to much of the CCAPM literature, we test this version of the model using long bond rates rather than equity returns. However, like most of the previous research on the CCAPM, the catching up with the Americans model fails to explain the relationship between consumption and asset returns. 相似文献
