This paper reworks Weisskopf's estimates of the effect of foreign capital inflow on domestic savings for a later time period. The Sudan is presented as an example of a public sector dominated economy, dependent on one major export crop and politically unstable. While Weisskopf's savings function had an indication of a negative relationship between public sector savings and official foreign capital inflow, problems of collinearity between the independent variables cast doubt on its utility for analysis of economies dependent on limited primary exports. The negative relationship between public sector savings and official is explained in terms of the expansion of the state's bureaucracy and military. 相似文献

This paper argues that, in the comparison of ‘aid vs trade’ options for developing countries, the estimation of the total impact of aid or trade (‘the indirect effects’) is more important than the evaluation of the direct effects of aid or trade. This argument arises from a critical examination of the prevailing approach to the evaluation of the worth of ‘aid or trade’. Particular references is made to the experience of the Sudan. 相似文献

To Help or Not to Help? The Good Samaritan Effect and the Love of Money on Helping Behavior 总被引:1,自引:0,他引:1

This research tests a model of employee helping behavior (a component of Organizational Citizenship Behavior, OCB) that involves
a direct path (Intrinsic Motives → Helping Behavior, the Good Samaritan Effect) and an indirect path (the Love of Money →
Extrinsic Motives → Helping Behavior). Results for the full sample supported the Good Samaritan Effect. Further, the love
of money was positively related to extrinsic motives that were negatively related with helping behavior. We tested the model
across four cultures (the USA., Taiwan, Poland, and Egypt). The Good Samaritan Effect was significant for all four countries.
For the indirect path, the first part was significant for all countries, except Egypt, whereas the second part was significant
for Poland only. For Poland, the indirect path was significant and positive. The love of money may cause one to help in one culture (Poland) but not to help in others. Results were discussed in the light of ethical decision making.

Abstract Bhattacharyya & Roussas (1969) proposed to estimate the functional Δ = ∫ ?∞/∞ f 2(x)dx by , where is a kernel estimate of the probability density f(x). Schuster (1974) proposed, alternatively, to estimate Δ by , where F n (x) is the sample distribution function, and showed that the two estimates attain the same rate of strong convergence to Δ. In this note, two large sample properties of are presented, first strong convergence of to Δ is established under less assumptions than those of Schuster (1974), and second the asymptotic normality of established. 相似文献

This article addresses the underresearched issues of marketing challenges and business strategies/models for emerging markets. It suggests that firms need to fundamentally rethink their business models and marketing policies for emerging markets. Although strategies focusing on product affordability and availability are necessary, identification of niche market segments and making clear choices about which segments to pursue, with what value propositions will promote great success. Moreover, strategic flexibility, local sourcing, engagement of nontraditional partners, and local entrepreneurship will be important factors for successful pursuit of the emerging markets. 相似文献

This paper considers three ratio estimators of the population mean using known correlation coefficient between the study and auxiliary variables in simple random sample when some sample observations are missing. The suggested estimators are compared with the estimators of Singh and Horn (Metrika 51:267–276, 2000), Singh and Deo (Stat Pap 44:555–579, 2003) and Kadilar and Cingi (Commun Stat Theory Methods 37:2226–2236, 2008). They are compared with other imputation estimators based on the mean or a ratio. It is found that the suggested estimators are approximately unbiased for the population mean. Also, it turns out that the suggested estimators perform well when compared with the other estimators considered in this study. 相似文献

We study international correlation and volatility dynamics of publicly traded real estate securities using monthly returns
from 1984 and 2006. We also examine, for comparison, the correlations among the corresponding stock markets. A multivariate
dynamic conditional correlation model captures the time-varying correlation within the full period. We confirm lower correlations
between all real estate securities market returns than those between the stock market returns themselves. Some significant
variations and structural changes in the correlation structure happened within the sample period. We detect a strong and positive
connection between real estate securities market correlations and their conditional volatilities. We also find the international
correlation structure of real estate securities and the broader stock market are linked to each other. Our results have economic
motivations regarding the potential integration of international real estate securities markets and the possibility of including
information on changing correlations and volatilities to design more optimal portfolios for international real estate securities.

This study presents a detailed typology of Jordanian consumers that identifies the effects of Covid-19 on their personal, social, and purchase and consumption patterns following the pandemic. Based on a qualitative approach using a sample of Jordanian consumers (N = 71), this study identifies three main types of consumers: the rational, suspicious, and cautious. All were distinguished by cognitive, emotional, and behavioral differences: the rational consumers viewed the pandemic as a natural occurrence, were willing to vaccinate, and took the opportunity to improve their lives and consumption behavior; the suspicious consumers viewed the pandemic as a man-made virus and refused to rationalize their behaviors and follow the social-distancing rules or vaccinate; and the cautious consumers were generally somewhere in between, and while they improved some aspects of their consumption, social, and personal lives, other aspects either remained the same or worsened. The findings have implications for managers and governmental bodies. 相似文献
