The study contains a theoretical analysis on the behavior of a between groups Lorenz Index. The variables affecting this index are utilized to construct between groups indices for white-non-white; rural-urban; above 65 yr old-younger; population groups by state for 1960. The constructed indices were then used as explanatory variables for the state total Lorenz Index. It was found that they explained over 80 per cent of the variance. Adding other socio-economic variables enabled us to explain over 90 per cent of the variance of state Lorenz indices. 相似文献

AbstractOver the past four decades considerable efforts have been taken to mitigate the growing burden of road injury. With increasing urbanisation along with global mobility that demands not only safe but equitable, efficient and clean (reduced carbon footprint) transport, the responses to dealing with the burgeoning road traffic injury in low- and middle-income countries has become increasingly complex. In this paper, we apply unique methods to identify important strategies that could be implemented to reduce road traffic injury in the Asia-Pacific region; a region comprising large middle-income countries (China and India) that are currently in the throes of rapid motorisation. Using a convolutional neural network approach, we clustered countries containing a total of 1632 cities from around the world into groups based on urban characteristics related to road and public transport infrastructure. We then analysed 20 countries (containing 689 cities) from the Asia-Pacific region and assessed the global burden of disease attributed to road traffic injury and these various urban characteristics. This study demonstrates the utility of employing image recognition methods to discover new insights that afford urban and transport planning opportunities to mitigate road traffic injury at a regional and global scale. 相似文献

Questions about universal service continue to evolve as information and communication technology advances, bringing new platforms, services, and business models. Concerns about exclusion remain, particularly in times of transition to new technologies and platforms. While the universal service literature is rich in econometric studies that indicate the drivers of household telephone penetration, without qualitative data directly from those households that experience phonelessness, we cannot understand the causes well enough to design effective policy. This research explores why people are phoneless in the current environment of increased platform and business model choices. Particular focus is placed on understanding the relationship between new technology, platforms and business models and phonelessness. Data is obtained from surveys completed by approximately 100 individuals in Massachusetts who are currently without any voice connection, either landline or mobile, or have been sometime in the past ten years. The survey includes questions about different platforms and communication services in order to learn how they have led to phonelessness. The results of the pilot study show that the vast majority of phoneless households do not choose to be phoneless. The study also shows that the most frequent causes of phonelessness in this population are unemployment and unpredictable bills. Many instances of unpredictable bills leading to phonelessness occur with wireless service or bundled services but are the result of business models for service provision rather than the platforms themselves. Prepaid wireless service is a market-based solution that helps households prevent phonelessness by reducing unpredictability. Universal service policy for voice and broadband can better reduce exclusion with greater attention to business models and practices versus technologies and platforms, and increased emphasis on prepaid service to reduce unpredictability. 相似文献

Conclusions Apart from the commodity mix effect, exports, imports consumption and production respond identically to changes in relative
capital endowment, regardless of whether one refers to physical capital, human capital or total capital. Hence, when allowing
technology and product mix to vary, one cannot distinguish between export goods and import goods in terms of capital intensity.
These conclusions are still in agreement with Hirsch [1977, p. 418] who argues “Poor countries export low capital-intensive
and import high capital-intensive goods, while rich countries import low capital-intensive and export high capital-intensive
goods.” The only response that is significantly different is due to the commodity mix effect. 相似文献

Mankiw and Reis propose the Sticky Information Phillips Curve (SIPC) as an alternative to the standard New Keynesian Phillips Curve to address empirical shortcomings in the latter. A SIPC for South Africa is estimated, and we find estimates of information updating probability between 0.69 and 0.81, somewhat higher than suggested by methods using micro‐evidence. Because the estimation requires data on expectations of current period inflation and output gap conditional on sequences of earlier period information sets, we provide a detailed analysis of the impact on our estimates of alternative proxies available in South Africa. 相似文献

This article is an attempt to evaluate the relative effect of sociological and economic factors on economic performance of occidental and oriental family farm operators in Israel. Unusual circumstances prevail in Israel, where farm operators with modern and traditional backgrounds co-exist within a modern economy. This setting allows us to evaluate the effect of the human factor under conditions of relative independence from the organizational set-up. Economic performance has been found to be closely associated with the level of formal schooling, status of women, degree of literacy and family size. 相似文献

To identify appropriate interventions that support sustainable land use; a farm household modelling approach is applied to analyze micro-economic supply reactions to various policy measures. The modelling framework links agro-technical and economic data, and takes both production and consumption decisions into account, allowing land use and production technology adjustments in accordance with farm household objectives. Different types of farm households are distinguished on the basis of their resource endowments, savings coefficients and time discount rate. Actual and alternative (sustainable) cropping and livestock activities for different weather regimes are defined for southern Mali. The effects on sustainable land use and expected farm household welfare of adopting alternative technologies and modifying prices, transaction costs, access to credit and land taxes are demonstrated. Even with full information on sustainable technologies, strong policy interventions are required to halt soil degradation. Structural policies proved to be more effective than price policies to reduce soil degradation while maintaining positive income effects. When prices are determined endogenously, structural policy loses some effectiveness as an incentive for sustainable land use due to the effect of additional supply on local cereal and meat Prices. 相似文献

A bivariate probit model was employed to jointly and separately estimate banana market participation decisions of buying and selling households in Rwanda and Burundi using household survey data. Selectivity bias was corrected for estimating the transacted volumes using Heckman's procedure. The results showed that transaction cost‐related factors such as geographical location of households, market information sources, and travel time to the nearest urban center influence market participation. Non‐price‐related factors such as security of land tenure, labor availability, off‐farm income, gender of the household head, and years of farming experience had a significant influence on the transacted volumes. Output prices had a significant correlation with sales volume, indicating price incentives increased supply by sellers. Generally, the findings suggest that policies aimed at investments in rural road infrastructure, market information systems, collective marketing, and value addition of banana products may provide a potential avenue for mitigating transaction costs and enhancing market participation and production of marketed surplus by rural households. 相似文献

In previous studies it was shown that the prevailance of a forward market in which a competitive firm can sell and buy unrestricted quantities of its output or of an input in employs in production eliminates the effects of the corresponding price uncertainties on production decisions. In this study we examine the effects on production decisions of narrowing the range of transactions a firm can perform. It turns out that restricting the firm only to hedge either in the output forward market or the input forward market makes the production decisions again sensitive to expected future prices and the attitude of the firm towards risk. 相似文献
