Foreign capital inflows,domestic savings and the price of political stability in the sudan: Weisskopf revisited

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.     

Factors Affecting Technical Efficiency among Coffee Farmers in Côte d’Ivoire: Evidence from the Centre West Region

This paper presents measures of technical efficiency for a sample of 81 peasant farmers in the low‐income region of Côte d’Ivoire. DEA techniques were used to compute farm‐level technical efficiency (TE) measures. The analysis reveals average levels of technical efficiency equal to 36 per cent and 47 per cent respectively for the CCR ( Charnes et al., 1978 ) and BCC ( Banker et al., 1984 ) models. These results suggest that substantial gains in output and/or decreases in cost can be attained given existing technology. In a second step analysis, two‐limit Tobit regression techniques were used to examine the relationship between TE and various farm/farmer characteristics. From a policy point of view, an important conclusion stemming from the analysis of our sample is that family size, membership to farmer's club or association and the origin of the farmer are the variables found to be most promising for action. The analysis suggests that policymakers should foster the development of the formal farmers’ club or association by building the capacity of the farmers. Our analysis also supports the argument for public sector involvement in the provision of information on labour force management to peasant farmers as a means to improve efficiency levels, and thus household incomes.     

‘When is trade more valuable than aid?’: Revisited

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.     

To Help or Not to Help? The Good Samaritan Effect and the Love of Money on Helping Behavior

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.

On asymptotic properties of an estimate of a functional of a probability density

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.     

Dynamics of Islamic Financing in Malaysia: Causality and Innovation Accounting

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.     

Imputation methods of missing data for estimating the population mean using simple random sampling with known correlation coefficient

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.     

Does training benefits lead to acquisition of livelihood assets and change in social status? Evidence from training of rice farmers

Livelihood assets which are considered and recognised for their life-supporting role contribute significantly and basically to the standard of living of people. These contributions as deemed more meaningful are considered necessary to farmers whenever an opportunity exists to diversify their investment. This study looked at how the benefits from increase in farmers' rice yield contribute to farmers ability to acquire livelihood assets to enhance their standard of living. A sample size of 265 from a population of 880 farmers trained by Japan International Cooperation Agency on sustainable rainfed low-land rice production technology was used. The objective was to establish how proceeds from rice sale influenced the acquisition of livelihood assets by farmers to support their standard of living. Using spearman rho correlation, it was found that a strong positive correlation exists between increase rice output and livelihood assets acquisition. It is recommended that the technology should be disseminated nationwide specially in low-land rice farming areas so that all farmers in the country could benefit.     

Correlation and Volatility Dynamics in International Real Estate Securities Markets

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.

Can the Euro Survive?

One of the fascinating aspects of the European debt crisis has been the resilience of the euro. For much of 2011, the euro was a key reserve currency, oblivious to the chaos ravaging European economies. Now, however, the gravity of the crisis is finally dragging down the euro. As the Euro zone debt crisis enters its third uncertain year, the question about whether the euro can survive rises. This paper argues that the euro can survive given policymakers still have in hand various tools. These tools include creating exit rules, implementing new stabilisation rules and instruments, adopting new fiscal policy, introducing conditional Eurobonds, using inflation differentials and providing more independence to the European Central Bank.
