The market as a mind is the implicit premise in any discussion on whether the market is rational or not. Still, its implications, in terms of ontology and epistemology, are hardly understood. In particular, this paper defines the market's version of the mind-body problem and labels it as finance's “hard” problem. Its denial by modern finance causes this dominant paradigm to fail in dealing with reality in general and to produce incomplete investment knowledge in particular. Finally, as part of facing up to this problem, this paper offers a glimpse at a practical approach which may enrich investment research. 相似文献

Optimal sequencing of resource extraction is typically studied for nonrenewable resources. We provide conditions for optimal use of multiple sources of a renewable resource and characterize the resulting extraction sequence, resource scarcity values, and (single) efficiency price path for two groundwater aquifers and an abundant alternative resource. Even with one demand, the optimal sequence depends on the differential opportunity costs of the two renewables. A numerical simulation for the South O‘ahu aquifer system, which also allows for different distribution costs, illustrates the case of using the “leakier” aquifer first and then switching to simultaneous use of both resources. The welfare gain from specialization relative to independent management is $4.7 billion. 相似文献

Southern bluefin tuna (Thunnus Maccoyii) is a global resource, which is critically endangered. The Committee for the Conservation of Southern Bluefin Tuna sets commercial quota levels for member nations, including Australia, each year. However, southern bluefin tuna is also a popular “trophy” fish with recreational anglers. The size of the total recreational catch, which is not included in the quota, is unknown but thought to be significant. This paper reports the findings of a study designed to estimate the recreational value of the non‐commercial southern bluefin tuna catch at Portland, in southwest Victoria. The results indicate that the size of the recreational catch at Portland is considerable and therefore significant in terms of the management of the fishery. Furthermore, the non‐market recreational values associated with the fishery are substantial with the on‐site recreational use value (consumer surplus) per person per visit estimated to be between $33 and $132 and the on‐site annual recreational use value of the fishery for one season is estimated to be between $449,533 and $1,325,124. 相似文献

Climate change predictions include forecasts of higher variability in rainfall and river flows leading to greater uncertainty about future availability of water across urban and agricultural sectors. Under conditions of water scarcity, it makes economic sense to facilitate the transfer of water from low‐ to high‐value users. This paper provides insights into the merits of water options contracts as a vehicle for facilitating trade and represents an alternative to the politically contentious permanent sale of water by agriculturalists. In addition, we provide some indicative results from an analysis of the feasibility of options contracts in an inter‐sectoral setting by considering their deployment to remove urban/industrial water restrictions. A case study of the urban community of Wangaratta and upstream agricultural interests has been selected. The objective is to identify the conditions under which option contracts might work and to highlight the important contract design features that need to be considered. 相似文献

The highly disputed effects of agricultural trade liberalisation are mostly simulated with static models. Our main objective in this paper is to evaluate the robustness of the static simulation results to the consistent modelling of dynamic behaviours and to the linked specification of price/return expectations. Focusing on the scenario of a complete trade liberalisation of arable crop markets by developed countries, we find that available static results are quite robust compared to dynamic specifications and to most expectation schemes. Endogenous market fluctuations due to expectation errors may appear following trade liberalisation. These fluctuations are nevertheless limited by the many feedback effects revealed by our general equilibrium framework. 相似文献

We present a model of optimal flow pollution control considering explicitly the dynamics of the corresponding assimilative capacity. We focus first on the degradation of this assimilative capacity triggered by pollution excesses and determine the intertemporal efficient pollution path, taking into account this ecological feedback. Our analysis shows that a minimum level of initial assimilative capacity is necessary to prevent its optimal extinction. We then allow for the restoration of assimilative capacity and characterize the conditions under which this option frees the optimal policy from the dependency on the initial conditions. In both cases our results call for environmental standards based on the shadow price of assimilative capacity that are stricter than the static optimum commonly used in flow pollution control. 相似文献

We use a panel data set of 59 developing countries over the 1972–1994 period to study the deforestation process. Relying on both parametric and semiparametric models, we examine nonlinearities and heterogeneity in the deforestation process. We first study the existence of an Environmental Kuznets Curve (EKC) and then analyze determinants of deforestation. Our data sample provides no evidence of an EKC. We also find that political institution failures may worsen the deforestation process in developing countries. 相似文献

I note an important distinction between the optimal price of environmental quality in a second-best world and the optimal level of environmental quality. Using an analytical general equilibrium model, I show that for reasonable parameter values, an increase in tax distortions (arising from an increase in required tax revenues) leads to a fall in the optimal Pigouvian tax rate even while environmental quality improves. In general, knowledge of the direction of changes in optimal environmental tax rates due to changes in the economy is not sufficient for understanding the impact on environmental quality. 相似文献

This paper identifies opportunities and constraints that low-income women face in accessing livelihoods in the renewable-energy sector in India through qualitative and quantitative research conducted in collaboration with The Energy Resources Institute (TERI) and the Self Employed Women's Association (SEWA) in 2012–13. Whereas previous research has focused on women mostly as end users of solar and biomass technologies, this research attempts also to understand women's potential as entrepreneurs, facilitators, designers, and innovators. Findings reveal that although access to technology and employment in the energy sector is limited by inadequate purchasing power and low social status, there is tremendous potential to create livelihoods for women at all levels of the energy supply chain. Broader findings indicate that women can gain optimal traction from employment in the energy sector only if there are wider socially progressive policies in place, including state intervention to create a robust social welfare infrastructure and accessible, high-quality, public services. 相似文献

ABSTRACTThe redistribution of household work is considered essential for effectively empowering women. This study examines the extent to which fathers’ evaluation of their wealth in relation to their wives’ influences fathers’ willingness to participate in childcare, a domain traditionally gender ascribed to wives. Data were gathered from a mothers’ survey and a fathers’ survey, each with a sample of 200, conducted in a rural and an urban district in Uganda in 2008. The study compares mean scores for perception and practice indices across three wealth categories: “wife is wealthier than husband,” “husband is wealthier than wife,” and “shared or equal wealth.” Data show that fathers are more likely to engage in childcare when husbands and wives share or have equal wealth than when there are wealth differences between spouses. The results suggest that policy should focus on raising women's economic endowment as well as public education that encourages progressive perceptions of gender roles. 相似文献
