Marginal areas of the world, including tropical highlands, tropical coastal zones, and arid lands, are problematical for development. They are ecologically special areas, often of vital consequence to the stability of more populated regions nearby. Commonly, their peoples are culturally distinct. To develop marginal areas it is suggested that “transformational” development may be appropriate. Transformational development recognizes the importance of equity and of working with existing resource systems already ecologically and culturally appropriate to the area. In marginal areas, a special application of transformational development could include incremental changes in existing systems and their connection to modern international systems so as to benefit the inhabitants of marginal areas and to supply commodities and goods demanded in the rest of the world. By rethinking ideas about resources, an exploratory framework for such transformation is examined. This framework uses the concept of “resource system”, a concept which might play an important part in the application of equitable future global development efforts. 相似文献

Roads, Land Use, and Deforestation: A Spatial Model Applied to Belize 总被引:24,自引:0,他引:24
Rural roads promote economic development, but they also facilitatedeforestation. To explore this tradeoff, this article developsa spatially explicit model of land use and estimates probabilitiesof alternative land uses as a function of land characteristicsand distance to market using a multinomial logit specificationof this model. Controls are incorporated for the endogeneityof road placement. The model is applied to data for southern Belize, an area experiencingrapid expansion of both subsistence and commercial agriculture,using geographic information system (GIS) techniques to selectsample points at 1-kilometer intervals. Market access, landquality, and tenure status affect the probability of agriculturalland use synergistically, having differential effects on thelikelihood of commercial versus semisubsistence farming. Theresults suggest that road building in areas with agriculturallypoor soils and low population densities may be a "lose-lose"proposition, causing habitat fragmentation and providing loweconomic returns. 相似文献

过去20年中,各国央行在抑制通胀方面几乎全面告捷,这使得许多政策制定者以为,他们几乎彻底解决了高通胀问题。正如很多定量分析和调查数据所显示的那样,市场参与者们已经认可了这个故事。但是,中央银行真的已经消灭通胀了吗? 相似文献

This study examines the relation between audit personnel salaries and office-level audit quality. We measure audit personnel salaries at the associate, senior, and manager ranks for Big 4 audit offices from 2004 to 2013, using unique individual-auditor-level data obtained from the U.S. Department of Labor. We find that offices that pay lower salaries have a higher percentage of clients that experience restatements. In related analyses, we also find lower levels of audit quality when audit employees are paid less, relative to other lines of service in accounting firms. Finally, we document positive and significant associations between salary and fees, suggesting that audit offices pass some of the cost of higher labor onto their clients. Overall, our findings provide important initial evidence on the role of audit salary and its relation to audit quality and audit fees. 相似文献

This article provides a guide to economic information on Australian resource projects. Three sources are described in some detail and their differences, strengths and weaknesses are discussed. As the data are under‐researched, some examples of how they can be used in economic analysis are mentioned. 相似文献

The removal of trade barriers has encouraged the entry of new competitors into formerly protected markets. This situation creates pressure on many small and medium enterprises (SMEs) in emerging economies such as Tanzania. Using a survey method and cross-sectional research design, the research examines three dimensions of entrepreneurial orientation (EO), namely: pro-activeness, risk-taking and competitive aggressiveness. Understanding their relationships and variance may help to improve our ability to explain SME performance. The findings contribute to how SME performance in emerging economies can be enhanced to enable SMEs to face challenges posed by competitor influx in the context of an open market economy. The findings indicate a strong relationship between EO dimensions and performance, with risk-taking and competitive aggressiveness moderating the effect of pro-activeness. The proposed model could predict 72% of the variance explained in SME performance. 相似文献

Identifying the value orientations of subjects participating in market or non-market decisions by having them participate in a ring game may be helpful in understanding the behaviour of these subjects. This experiment presents the results of changes in the centre and the radius of a value orientations ring in an attempt to discover if the measured value orientations exhibit income or displacement effects. Neither significant income effects nor displacement effects are identified. An external validity check with a voluntary contribution game provides evidence that value orientations from rings centred around the origin of the decision-space explain significant portions of voluntary contributions while value orientations from displaced rings do not. 相似文献

The relationship between unethical peer behavior and observers?? unethical behavior traditionally has been examined from a social learning perspective. We employ two additional theoretical lenses, social identity theory and social comparison theory, each of which offers additional insight into this relationship. Data from 600 undergraduate business students in two universities provide support for all the three perspectives, suggesting that unethical behavior is influenced by social learning, social identity, and social comparison processes. Implications for managers and future research are discussed. 相似文献

The contextual nature of the predictive power of statistically-based quarterly earnings models 总被引:2,自引:2,他引:0
We present new empirical evidence on the contextual nature of the predictive power of five statistically-based quarterly earnings
expectation models evaluated on a holdout period spanning the twelve quarters from 2000–2002. In marked contrast to extant
time-series work, the random walk with drift (RWD) model provides significantly more accurate pooled, one-step-ahead quarterly
earnings predictions for a sample of high-technology firms (n = 202). In similar predictive comparisons, the Griffin-Watts (GW) ARIMA model provides significantly more accurate quarterly
earnings predictions for a sample of regulated firms (n = 218). Finally, the RWD and GW ARIMA models jointly dominate the other expectation models (i.e., seasonal random walk with
drift, the Brown-Rozeff (BR) and Foster (F) ARIMA models) for a default sample of firms (n = 796). We provide supplementary analyses that document the: (1) increased frequency of the number of loss quarters experienced
by our sample firms in the holdout period (2000–2002) vis-à-vis the identification period (1990–1999); (2) reduced levels
of earnings persistence for our sample firms relative to earnings persistence factors computed by Baginski et al. (2003) during earlier time periods (1970s–1980s); (3) relative impact on the predictive ability of the five expectation models
conditioned upon the extent of analyst coverage of sample firms (i.e., no coverage, moderate coverage, and extensive coverage);
and (4) sensitivity of predictive performance across subsets of regulated firms with the BR ARIMA model providing the most
accurate predictions for utilities (n = 87) while the RWD model is superior for financial institutions (n = 131).

This article develops and empirically implements an arbitrage-free,dynamic term structure model with "priced" factor and regime-shiftrisks. The risk factors are assumed to follow a discrete-timeGaussian process, and regime shifts are governed by a discrete-timeMarkov process with state-dependent transition probabilities.This model gives closed-form solutions for zero-coupon bondprices, an analytic representation of the likelihood functionfor bond yields, and a natural decomposition of expected excessreturns to components corresponding to regime-shift and factorrisks. Using monthly data on U.S. Treasury zero-coupon bondyields, we show a critical role of priced, state-dependent regime-shiftrisks in capturing the time variations in expected excess returns,and document notable differences in the behaviors of the factorrisk component of the expected returns across high and low volatilityregimes. Additionally, the state dependence of the regime-switchingprobabilities is shown to capture an interesting asymmetry inthe cyclical behavior of interest rates. The shapes of the termstructure of volatility of bond yield changes are also verydifferent across regimes, with the well-known hump being largelya low-volatility regime phenomenon. 相似文献
