We show that in large finite economies, core allocations can be approximately decentralized as Nash (rather than Walras) equilibrium. We argue that this exercise is an essential complement to asymptotic core equivalence results, because it implies that in some approximate sense individual attempts to manipulate the decentralizing prices cannot be beneficial, which fits precisely the interpretation of asymptotic core convergence, namely the emergence of price taking. 相似文献

The “justice of markets” is intricately connected to the treatment of the poor and the disadvantaged in market economies.
The increased interest of multinational corporations in low-income market segments affords, on one hand, the opportunity for
a more inclusive capitalism, and on the other, the threat of greater exploitation of poor and disadvantaged consumers. This
article traces the contributions of Catholic Social Teaching and its basic principles toward providing insight into what constitutes
“justice” in such “marketing to the impoverished” situations. 相似文献

It has long been recognized that accounting and finance students need multidisciplinary skills and most degree courses reflect this in the curriculum. In addition, the growth of business administration courses, with a high accounting and finance content, and the constant call for relevance and ‘real world’ application, has persuaded many academics that educational progress can be made by employing project-based group work to bring together diverse skills and disciplines. This paper endorses that view, but suggests that careful thought is required to match the aims of the project with the developing skills and experience of the student groups. It explores the role of project clients and student learning and also the level of faculty involvement necessary to fulfil learning objectives. These issues are explored within the context of a project on mergers and acquisitions, which combines strategy, economics, accounting and behavioural considerations and has been employed on full-time MBA courses at one UK university (disguised as ‘Utopia’ in the paper) for more than 20 years. Experience from the project suggests that renovation of old methods is often preferable to major innovations and that the involvement of outside clients needs to be thought through carefully. A semi-live close-bounded version of the project is shown to work better than an open-ended pure consultancy project. 相似文献

We examine the issues of hypothetical bias, demand revelation, and gender differences in a threshold public goods experiment
with heterogeneous induced-values. First, we find no evidence of hypothetical bias in our threshold provision public goods
experiments, despite the fact this is an open-ended type mechanism. Our results support recent experimental findings that
use induced-values to investigate hypothetical bias. Second, we investigate the demand revealing performance of real and hypothetical
payments and find no evidence that real payment performs better than hypothetical payment in our experiments. Third, we examine
whether payments, real and hypothetical, are positively related to induced-values. Our results suggest there is statistical
evidence that payments are positively related to true values. Finally, we examine the effect of gender on real and hypothetical
payments in our experiment. The results show that gender matters for contributions through both real and hypothetical payments,
after controlling for true values as well as socio-economic variables. Results also indicate that females are more likely
to truthfully reveal their value than males through hypothetical payments, but gender is not significant for truthfully revealing
their value through real payments. 相似文献

The economic significance of conditioning information in the presence of costly short‐selling is investigated. Using a compact testing framework, results demonstrate that fixed‐weight stock‐bond portfolios appear inefficient with respect to stock‐bond portfolios with weights determined by extant predictors. However, this result is highly dependent on ex ante knowledge of the predictor set and the ability to short‐sell at low cost. In the absence of such conditions, fixed‐weight stock‐bond portfolios appear efficient with respect to conditioning information. 相似文献

Most existing economic analyses of optimal groundwater management use single-cell aquifer models, which assume that an aquifer responds uniformly and instantly to groundwater pumping. In this paper, we develop an economic model of groundwater management that explicitly incorporates spatial dynamic groundwater flow equations. Calibration of our model to published economic studies of specific aquifers demonstrates that existing studies generally incorrectly estimate the magnitude of the groundwater pumping externality relative to spatially explicit models. In particular, for large aquifers with surface areas of thousands of square miles, the marginal pumping externality predicted by single-cell models may be orders of magnitude less than that predicted by a spatially explicit model, even at large distances from a pumping well. Conversely, for small aquifers with areas of a few hundred square miles or less, single-cell models reasonably approximate the pumping externality. Application of single-cell models to inappropriate settings may result in misleading policy implications due to understatement of the magnitude and spatial nature of the groundwater externality. 相似文献

In 2013, Ethiopia's Agricultural Transformation Agency introduced the Wheat Initiative to increase smallholder productivity. In this article, we measure the impacts of the Wheat Initiative package of technologies, and its marketing assistance component alone, on yields among a promotional group of farmers. The package includes improved techniques, improved inputs, and a guaranteed market for the crop. Relying on crop‐cut measures and farmers’ own assessments, we find that full package led to an average 14% higher yields. Implementation of the Wheat Initiative was successful in making certified seed and fertilizer accessible to farmers and increasing their uptake, though only 61% of the intervention group adopted row planting and few farmers received marketing assistance. The measured yield difference may underestimate the true yield difference associated with the technology because of incomplete adoption of the recommended practices by intervention farmers and adoption of some practices by control farmers. 相似文献

The rapid growth in aquaculture production, globally and in Bangladesh is well documented. Over 2000–2010, per capita production of aquaculture grew 76%, while the consumer price of fish declined 45%. Previous studies have suggested pro‐poor effects of aquaculture based on fish production and consumption patterns. This study attempts to quantify the contribution of aquaculture to income growth and poverty reduction in Bangladesh, using household survey data and a microsimulation approach based on an expanded version of Deaton's concept of net benefit ratio. We estimate that aquaculture's contribution to income growth between 2000 and 2010 was 2.1%, including both price and quantity effects. This income growth was translated into poverty reduction of 1.7 percentage points. Although these estimates seem small, they represent almost 10% of the overall poverty reduction in Bangladesh during the first decade of the 21st century. Put differently, of the 18 million Bengalis who escaped poverty during 2000–2010, about 1.8 million of them managed to do so because of the rapid growth in aquaculture, which contributed to rural income while making fish more accessible to consumers. 相似文献

This article investigates the impact of sectoral production allocation, energy usage patterns and trade openness on pollutant emissions in a panel consisting of high‐, medium‐ and low‐income countries. Extended STIRPAT (Stochastic Impact by Regression on Population, Affluence and Technology) and EKC (Environmental Kuznets Curve) models are conducted to systematically identify these factors driving CO2 emissions in these countries during the period 1980–2010. To this end, the study employs three different heterogeneous, dynamic mean group‐type linear panel models and one nonlinear panel data estimation procedure that allows for cross‐sectional dependence. While affluence, nonrenewable energy consumption and energy intensity variables are found to drive pollutant emissions in linear models, population is also found to be a significant driver in the nonlinear model. Both service sector and agricultural value‐added levels play a significant role in reducing pollution levels, whereas industrialisation increases pollution levels. Although the linear model fails to track any significant impact of trade openness, the nonlinear model finds trade liberalisation to significantly affect emission reduction levels. All of these results suggest that economic development, and especially industrialisation strategies and environmental policies, need to be coordinated to play a greater role in emission reduction due to trade liberalisation. 相似文献
