《Food Policy》2020
Although optimal monetary policy stabilizes food inflation theoretically, empirical studies remain limited not only in the context of volumes and the estimation approaches, but are focused on selected advanced and emerging countries to the neglect of Africa where poverty and dominance of food in the consumption basket are more pronounced. We provide empirical evidence in the context of South Africa using quantile regressions. Rising food prices are destabilized even further by restrictive monetary policy; a finding that has ramifications for inflation targeting, especially given that a quarter of the country’s population is food poor. 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

An issue in the pricing of contingent claims is whether to account for consumption risk. This is relevant for contingent claims on stock indices, such as the FTSE 100 share price index, as investor’s desire for smooth consumption is often used to explain risk premiums on stock market portfolios, but is not used to explain risk premiums on contingent claims themselves. This paper addresses this fundamental question by allowing for consumption in an economy to be correlated with returns. Daily data on the FTSE 100 share price index are used to compare three option pricing models: the Black–Scholes option pricing model, a GARCH (1, 1) model priced under a risk-neutral framework, and a GARCH (1, 1) model priced under systematic consumption risk. The findings are that accounting for systematic consumption risk only provides improved accuracy for in-the-money call options. When the correlation between consumption and returns increases, the model that accounts for consumption risk will produce lower call option prices than observed prices for in-the-money call options. These results combined imply that the potential consumption-related premium in the market for contingent claims is constant in the case of FTSE 100 index options. 相似文献

Household surveys are playing an increasingly important role in the measurement of poverty and well-being around the world. The Living Standards Measurement Study, which was begun in the World Bank under the guidance of Graham Pyatt in 1979, has played an important role in this movement. Its surveys are widely used within the Bank to measure consumption-based poverty, and survey data are now the exclusive basis for the global poverty counts. This paper discusses a number of unresolved issues in using consumption-based surveys for measuring well-being, including the choice of a money-metric versus welfare-ratio approach, the collection of suitable price information, the effects of measurement error on estimation, and methods for correcting per capita consumption for the demographic structure of the household. 相似文献

Extant work on costs of financial instability focuses on fiscal costs and declines in aggregate GDP following banking crises. We estimate effects of banking and currency crises on consumption in 19 OECD countries, showing consumption plays an important role in the adjustment following a crisis, and effects are not captured solely by the impact of crises on standard consumption determinants, income and wealth. Additional effects, attributable to factors such as time-varying confidence, uncertainty and credit rationing, are aggravated by high and rising leverage, despite financial liberalisation easing liquidity constraints. High leverage implies that banking crises taking place now could have greater incidence than in the past. 相似文献

This paper synthesizes recent research and new empirical findings to build a more comprehensive understanding of developments in China’s dairy sector. China’s tremendous rise in dairy demand has been driven by several mutually reinforcing factors: including rapid income growth, promotion by the government and dairy industry, changes in urban lifestyles, and the development of new, more sophisticated marketing channels. Domestic milk output has grown to satisfy rising demand largely by increasing the dairy herd. Substantial increases in productivity have been achieved through technology adoption, but there is evidence that the torrid growth has created inefficiencies because adaptations to marketing rules, infrastructure, and institutions have not kept pace with the changing environment. These results suggest there is ample room for future growth in both domestic milk production and dairy demand, but multinational firms and imported products will likely play and increasing role as China’s dairy market continues to develop. 相似文献

Forests produce benefits over and above the revenue yielded from timber and other wood based products. Most important among these may be the recreational benefits for visitors, which have been examined in several studies. Total benefits for residents are perhaps more accurately captured in property values since, ceteris paribus, the price of a house reflects willingness to pay to live near an environmental amenity such as a forest to gain access to it, and also the amenity (non-use) value of the forest in so far as it creates a pleasant landscape. However, the total non-priced value of forestry is not the sum of HPM and ITCM benefit estimates. Recreational benefits will typically be less, and will be subsumed in the HPM estimates, since the hedonic price is partly induced by the value of recreational access. 相似文献

This paper examines the case of a good, polluting in consumption, whose pollutive content is restricted by a government with strong environmental policies. When foreign producers are unable to comply with the restrictive environmental standard of such a country, to which they wish to export, they often allege that those standards constitute illegal barriers to free trade. An example of such a good is gasoline, excessively pollutive formulations of which are prohibited from importation into the United States by the 1970 Clean Air Act. Rather than banning them, such imports should be taxed, along with the domestically produced substitute good, according to their respective pollutant contents. This would foster economic efficiency and should be more acceptable to foreign producers than the outright prohibition mandated by the Clean Air Act. The results of this paper reaffirm the argument in a previous article in this journal (Socio-Economic Planning Sciences 29 (1995) 187), though the countries’ roles in the two papers are reversed, that free trade and Pigouvian environmental policies increase international welfare. 相似文献

Hedonic models and air pollution: Twenty-five years and counting 总被引:2,自引:1,他引:2
This paper reports a meta analysis of how effectively hedonic property models have detected the influence of air pollution on housing prices. Probit estimates are reported describing how data, model specification, and local property market conditions in cities represented in thirty-seven studies influence the ability of hedonic models to uncover negative, statistically significant relationships between housing prices and air pollution measures.Partial support for this research was provided by the Russell Sage Foundation. Thanks are due David Cordray, Heidi Hartman, and Larry Hedges of the Foundation's Meta-Analysis Panel for constructive comments, to Ray Palmquist for suggestions and assistance in assembling the results from his studies, to Rick Freeman and Tom Tietenberg and two anonymous referees for comments on the research, and to Barbara Scott for constructive editing of earlier drafts of this paper. 相似文献

消费文化、认知偏差与消费行为偏差 总被引:11,自引:1,他引:11
本文放松了理性经济人假设,在行为经济学双曲线贴现模型框架下,以"自我控制"认知偏差及相应的模型参数设定对东西方消费文化差异进行了技术表达,进而阐明了消费过度(欧美国家)和消费不足(东亚国家)这两类消费行为偏差的形成机制。本文采用全球48个国家和地区1978—2007年的面板数据,以儒家虚拟变量和性生活指数作为消费文化的替代变量检验了文化与消费的关系。结果表明,在解释东西方消费率差异时,预防性储蓄等传统理论的解释力远低于不可观测的国家个体效应。儒家虚拟变量和性生活指数能分别解释国家个体效应的28%和58%。这表明消费文化等不随时间改变的个体因素比传统变量更能解释各国居民的消费差异。实践层面上,双曲线贴现模型中锁定技术能有效纠正"自我控制"认知偏差,从而消解儒家文化对消费的深度抑制,可为扩大内需政策创新提供思路启发和技术支撑。 相似文献
