Computable general equilibrium models are used to study the short-run impact of fluctuating primary commodity prices on the economies of Columbia, Ivory Coast and Kenya. The results indicate that these economies are destabilized by primary commodity price fluctuations unless governments act to hold real domestic absorption constant. To achieve this, however, would require foreign exchange reserves in excess of the level normally available to these governments for the purpose of stabilizing domestic economic activity. 相似文献

Zusammenfassung Ein Test der Effizienz von Warenterminm?rkten. — In Reaktion auf die UNCTAD-Pl?ne zur Stabilisierung von Rohstoffpreisen durch
beh?rdliche Ausgleichslager hat sich die Diskussion um Warenterminm?rkte als alternative, marktkonforme Stabilisierungsinstrumente
erneut entfacht. Eine wesentliche Voraussetzung für den stabilisierenden EinfluΒ der Termingesch?fte auf die Kassapreise von
Rohstoffen ist, daΒ die Terminm?rkte ?effizient? sind, d. h., die Terminmarktpreise s?mtliche jeweilig verfügbare Information
widerspiegeln. In diesem Aufsatz wird die Effizienz der Terminm?rkte für fünf wichtige Rohstoffe (Kupfer, Zinn, Zucker, Kakao
und Kaffee) des UNCTAD-Programms getestet. Dazu werden ARIMAZeitreihenmodelle der Kassapreise gesch?tzt und die Entwicklungen
ex post vorhergesagt. Die so gewonnenen Ex-post-Prognosen sind effiziente Vorhersagen, da die Modelle alle systematischen
Komponenten einer Zeitreihe erfassen, so daΒ der unerkl?rte Rest zufallsverteilt ist. Ein Vergleich zwischen dem mittleren
quadrierten Vorhersageirrtum der Prognosemodelle und dem der Warenterminm?rkte zeigt, daΒ die Terminm?rkte in allen F?llen
künftige Entwicklungen ebensogut oder besser anzeigen als die Modelle. Folglich kann die Hypothese, daΒ die untersuchten M?rkte
im oben beschriebenen Sinn effizient sind, nicht verworfen werden.
Résumé Un test de l’efficacité des marchés á terme des matières premières. — cet article nous faisons un test ?demi-fort? sur l’efficacité de marché pour cinq matières — le cuivre, l’étain, le sucre, le cacao et le café — pour lesquelles la CNUCED a proposé de stabiliser les prix par des schemes des stocks régulateurs. Les résultats indiquent que, pour la période observée, on ne peut pas refuser 1’ hypothèse que les marchés á terme de ces matières premières sont efficaces dans le sens que le marché emploie toutes les informations publiquement disponibles en formant les expectatives sur les prix au comptant futurs. Nous concluons que la stabilisation des prix au comptant de quelques matières premières pourrait être regardée comme alternative favorable vis-á-vis les schemes des stocks régulateurs de la CNUCED.
Resumen El test de la eficiencia de mercados a futuro de productos primarios. — En este articulo se realiza un test de eficiencia de mercado de forma ?semi-fuerte? para cinco productos, espedficamente, cobre estafio, azücar, cacao, y café, cuyos precios UNCTAD ha propuesto estabilizar a través de esquemas de stocks amortiguadores. Los resultados indican que para el periodo estudiado, la hip?tesis de que los mercados a futuro para estos productos son eflcientes en el sentido de que el mercado emplea toda la informacion que se puede obtener püblicamente, informando sobre expectativas de los precios puntuales futuros, no puede ser rechazada. Se concluye entonces, que la estabilización de los precios puntuales para algunos productos primarios a través de mercados a futuro puede ser considerada como una alternativa favorable frente a los esquemas de Stocks amortiguadores de UNCTAD.相似文献

The effects of extrinsic product cues on consumers’ perceptions of quality, sacrifice, and value 总被引:2,自引:0,他引:2
The authors report the results of two experiments designed to test the effects of extrinsic cues—price, brand name, store
name, and country of origin—on consumers’ perceptions of quality, sacrifice, and value. The results of the experiments support
hypothesized linkages between (a) each of the four experimentally manipulated extrinsic cues and perceived quality, (b) price
and perceived sacrifice, (c) perceived quality and perceived value, and (d) perceived sacrifice and perceived value. The results
also indicate that the linkages between the extrinsic cues and perceived value are mediated by perceived quality and sacrifice.

Social media,an emerging platform for relationship building: A study of engagement with nongovernment organizations in India 下载免费PDF全文
Siddharth Tripathi Sanjeev Verma 《International Journal of Nonprofit & Voluntary Sector Marketing》2018,23(1)
The purpose of this study is to explore the major determinants of nongovernment organizations (NGOs) engagement and relationship building on social media in India. Netnography with a metaphoric grounded analysis is used for the data analysis to identify these determinants, and a conceptual framework is proposed to inform the strategic direction of NGOs. The findings suggest that supporters engage with NGOs largely for personal and organizational reasons. Emotions, trust, and information needs emerge as the primary personal drivers for engagement, whereas organizational accountability, performance, brand image, and transparency emerge as organizational drivers. Behavioural intention mediates the relationship between the drivers of engagement and supporter contributions. The study suggests that as the number of supporters on social media platforms is rapidly increasing, NGOs should recognize the importance of the supporter experience while designing their marketing strategies. Given the peculiarity of supporter behaviour in relationship building by NGOs, the inclusion of more supporters may improve the welfare of society. 相似文献

Does corruption affect income inequality and poverty? 总被引:2,自引:0,他引:2
This paper provides evidence that high and rising corruption increases income inequality and poverty. An increase of one
standard deviation in corruption increases the Gini coefficient of income inequality by about 11 points and income growth
of the poor by about 5 percentage points per year. These findings are robust to use of different instruments for corruption
and other sensitivity analyses. The paper discusses several channels through which corruption may affect income inequality
and poverty. An important implication of these findings is that policies that reduce corruption will most likely reduce income
inequality and poverty as well.

Using a panel of 46 emerging market economies from 1997 to 2008, this paper investigates the key determinants of country risk premiums as measured by sovereign bond spreads. Unlike previous studies, the results indicate that both political and fiscal factors matter for credit risk in emerging markets. Lower levels of political risk are associated with tighter spreads, particularly during financial turmoil. Efforts at fiscal consolidation narrow credit spreads, especially in countries with high initial public debt levels. The composition of fiscal policy also matters as higher public investment lowers spreads as long as the fiscal position remains sustainable and the fiscal deficit does not worsen. 相似文献

This paper analyses the average taxpayer's demand for merit goods, namely, education and health, in Mauritius, a small developing island state. To study these development-related goods, a fresh methodology is employed that captures the characteristics of the Mauritian economy. The empirical evidence relates to the post-independence period of more than three decades, 1973 to 1999 and beyond. The respective demand elasticities for each merit good are analysed and evaluated. The findings indicate that, contrary to the conventional theory of demand, beneficiaries tend to demand more of such goods when their prices are increased, and less when they are decreased. The rationale for this behaviour is that people, in general, and taxpayers, in particular, being quality conscious, increase their demand when they are asked to pay more, expecting in return an improvement in the quality of services. However, there is evidence that over these three decades users' preferences have shifted, particularly in the case of education, towards private provision, indicating less reliance on public sector provision, and that during the years of structural adjustments the demand for these services was severely suppressed. 相似文献

In a consumeristic society, brands have become a signal to the identity and personality of the users. Apple Incorporate has been one of the most successful marketers, of modern times, with its iconic range of “i” devices that have a cult‐like following. The growth of “individualistic” society has also been credited with, as an important reason, for the success of the brand. Societies and people high in terms of individualism also tend to be more narcissistic. This study is an attempt to ascertain whether the use of the Apple iPhone is an indication of Narcissism. The results indicate an overall higher narcissistic score among users and aspirers of iPhone. However, iPhone users exhibit higher scores only in adaptive narcissism—indicative of leadership and authority and not in maladaptive narcissism—indicative of Entitlement Exploitativeness and Grandiose Exhibitionism; in comparison to nonusers. The results of the study have various managerial implications that may range from personality assessment to designing marketing messages and improving employee leadership and authority. 相似文献
