Intertemporal Equity and Hartwick's Rule in an Exhaustible Resource Model*

In a standard exhaustible resource model, it is known that if, along a competitive path, investment in the augmentable capital good equals the rents on the exhaustible resource (known as Hartwick's rule), then the path is equitable in the sense that the consumption level is constant over time. In this paper, we show the converse of this result: if a competitive path is equitable, then it must satisfy Hartwick's rule.

修辞情景背后的动机说——以尼克松访华系列演说为例

演讲与修辞的渊源关系并未促进修辞视角下的外交演讲研究。就尼克松访华系列演说为例,学术界对其进行的修辞分析有所欠缺。分析尼克松访华演说所面临的修辞形势及其应对策略的同时,重点考察尼克松总统的受众意识。尼克松访华系列演说运用了娴熟的语言手段最大范围地争取了受众的认同、缓解了敌意,进而促使了受众接受访华举措。     

马克思主义中国化的个体主体及其实践本质

个体主体是推进马克思主义中国化的重要主体力量,现代市民社会的个性化要求实现了对马克思主义中国化个体主体的实践形塑;“个体解读——个体内化——个体应用”内在地构成了马克思主义中国化的微观运行机制．马克思主义中国化个体主体的概念内涵彰显的是个体主体的本质存在,而其概念外延彰显的则是个体主体的多重本质表现样态。     

企业竞争战略范式演化与新发展

自20世纪末以来,全球化、知识化与信息化的浪潮极大地改变着全球经济环境,在这种背景下,经典企业竞争战略范式吸收新的竞争要素从而获得新发展;与此同时,基于快速反应能力和复杂性科学的新的竞争范式得以形成和确立。本文着眼于范式层面对竞争战略发展过程进行分析,意在揭示它们之间存在的联系和差异,概括企业竞争战略理论发展与变迁的历史逻辑。     

Pure Altruism,Consumer Behavior and Choice Modeling*

An important assumption underlying non‐market valuation is that it is not the environment but the human preference that is valued. This paper attempts to test whether individual consumer behavior is influenced by a purely altruistic motive, examining the attitude of hikers towards the hypothetical removal of the Muju ski resort from the Mount Togyu National Park in South Korea. Data were collected from samples of hikers and skiers who visited the national park. The respondents were forced to consider trade‐offs between the recovery of the lost environmental assets in the Muju ski resort area, skiers’ additional travel time, and willingness‐to‐pay amounts for the hypothetical environmental improvement. It was found that hikers did not take into account skiers’ disutility represented by additional travel time.     

Technical Inefficiency and Production Risk in Rice Farming: Evidence from Central Luzon Philippines*

There have been many previous studies of technical inefficiency in rice production in the Philippines, but none has focused simultaneously on production risk and technical inefficiency at the farm level. Rice production is inherently risky because of the heterogeneous production environment. In this study, we analyze technical inefficiency in a rainfed lowland rice environment in Central Luzon using a stochastic frontier production function with a heteroskedastic error structure. An 8‐year panel dataset collected from 46 rainfed rice farmers was used to estimate flexible functional specifications. Over the whole period, the average technical efficiency was found to be 79 percent. Results indicate that there is a high degree of variability in technical efficiency estimates, which can be attributed to the instability of farming conditions in the rainfed lowland environment. Mean output was signifificantly influenced by area planted to rice, labor and the amount of fertilizer used. Consequently, these inputs were found to be risk‐increasing, whereas herbicide was found to be a risk‐reducing input.     

Surface Coal Mining and Human Health: Evidence from West Virginia

This article presents the first panel-data evidence of a human health externality from the air pollution generated by surface coal mining. In West Virginia, a standard deviation increase in a county's exposure to surface coal mining is associated with 9.85 more asthma hospitalizations per 100,000 residents in a given quarter. Interpreted causally, this suggests over $11 million in hospitalization costs over the 6-year study period. The study builds on earlier cross-sectional research by controlling for unobserved county-level heterogeneity, and by defining more accurate measures of exposure. Both methods are shown to reduce the bias associated with earlier estimates of coal mining's effect on health. Young and elderly women demonstrate the largest sensitivities to surface mining. Falsification tests reveal that neither hernias nor bone fractures demonstrate any relationship with surface mining activity.     

China's macroeconomic stability – an empirical study based on survey data

A complete financial stability analysis should include investigation on macroeconomic stability since macroeconomic development and potential imbalance can increase the financial instability and trigger a financial crisis. Survey data of rating on China's macroeconomic stability is analyzed by estimating an ordered logit model with random effect. Among the candidate macroeconomic indicators, we found that inflation is the key variable that determines China's macroeconomic stability, followed by the change in budget balance and GDP growth gap.
