We empirically investigate the relationship between the return on collateral and monetary policy implementation in the channel system. Recent developments in monetary theory suggest that the return on government assets which measures the opportunity cost of holding collateral should have negative impacts on the interest-rate spread and the interbank market rate. The central bank should set a higher spread when the return on collateral is below a cutoff but implements a lower spread when the return on collateral is higher than the cutoff. The interbank market rate tends to lie above the policy target rate when the return on collateral is low and vice versa. We use data from Eurozone area and six industrialized countries to test these theoretical implications. We propose two econometric models: one is more structural and closely related to the monetary model to test the negative relationships, and the other is based on the threshold autoregression model to detect the potential cutoffs. Our findings provide conditional support for the negative impact of return on collateral. (JEL E40, E52, E58)  相似文献

Abstract

The literature on supplier integration’s (SI) impact on firm performance is intertwined with mixed findings in terms of definitional differences, study context, specific integration components, and the types of relationships examined. This study contributes to the supplier integration and firm performance (SI-FP) literature by investigating how and when supplier integration influences firm performance. Drawing on the relational view, the resource-based view, and the Dynamics Capability theories, we suggest that improvements in firm performance from the supplier integration perspective are dependent on gains in operational capabilities. We test this dependency with survey data from firms in Ghana, a developing economy. The results show positive significant relationships between supplier integration and competitive operational capabilities and between supplier integration and firm performance. Our results highlight the importance for managers in developing economies and elsewhere to improve their firms’ operational capabilities and competitiveness by investing in supplier integration. We also discuss implications of these findings for research.  相似文献

In 2006, the Ghanaian government, in partnership with the United Nations Children's Fund (UNICEF), began to reform the child welfare system. The main aim of this reform was to provide a sustainable and culturally appropriate system of care for children without parental care by shifting from an institutional‐based model to a family and community‐based one. Drawing on existing peer‐reviewed and grey literature, this article provides an overview of the major components of the reform, including reintegration with the extended family, foster care and adoption. In addition, the article discusses the prospects and challenges involved in achieving the reform's intended component. Key Practitioner Message: ● Use community development techniques to raise the resources needed to provide family support services for vulnerable families;Social work practitioners partner with non‐governmental organisations to train community members as para‐social workers;Social workers, especially in developing countries, understand the challenges they face when embarking on deinstitutionalisation.  相似文献

The British withdrawal from the Atlantic Slave Trade fostered the expansion, rather than retrenchment of slavery within Africa. It also spurred a shift in the pre-nineteenth-century gendered pattern of slaveholding. This paper examines the extent to which radical economic changes altered the gendered structure of slaveholding in post-abolition Ghana. It argues that the British prohibition liberalised slaveholding conditions and resulted in a reconceptualisation of the value of slaves which breached the tradition of restricted female proprietorship of slaves, and also led to increased women's earning capacity, slave acquisition and use, as well as the scale of their holdings.  相似文献

This qualitative case study explores the challenges facing children reunified with their families from an orphanage in Ghana. Eight children, their biological families, and two social workers participated in semi‐structured interviews and shared their experiences and views. The study found that challenges facing the children include educational issues, poor living conditions and social isolation within their communities. The factors causing the challenges included the financial difficulties facing caregivers due to the lack of support, limited preparation for the children and their families for the reunification and the children's limited participation in the decisions concerning such reunification.  相似文献

Introduction: The etiology of benign prostatic hyperplasia (BPH) remains a mystery to scientists; estrogen/androgen imbalance in aged men has been implicated.

Methods: Thirty (30) apparently healthy men and newly diagnosed BPH patients were recruited from the Ghana Police Hospital. Lower urinary tract syndrome (LUTS) and prostate volume were assessed via the prostate symptom score sheet (IPSS) and abdominopelvic scan, respectively. Laboratory assays for total prostate specific antigen (tPSA) and hormones [androstenedione (AED), testosterone (T), dihydrotestosterone (DHT), androstanedioladiol (3α-adiol), androstanediol (3β-diol), estrone (E1) and estradiol (E2)] were performed via ELISA techniques. Non-parametric analyses were employed. p?Results: AED was significantly higher in controls compared to the BPH patients. AKRIC2 (3α-diol/DHT) was significantly higher in the BPH group (p?p=?0.029). Age correlated negatively with T, while a negative correlation was observed between TIPSS and 3β-diol and AKRIC1. Also, prostate volume correlated negatively with fT.tPSA correlated positively with E2 and aromatase activity (E2/T) and negatively with fT. On multiple linear regression, DHT and 3β-diol remained independent predictors for TIPSS and fT for tPSA.

Conclusion: Estrogens and androstanediols seem to play a role in BPH development.  相似文献

In the past few decades, the number of children requiring out‐of‐home care in the developing world has risen sharply. Many children end up in institutions where they make a transition to adulthood. Little is however known about the social support available to young people during and after they leave care. This study examines the sources and kinds of support as well as the barriers to social support for a group of care leavers from a children's village in Ghana. The participants used a combination of formal and informal sources for their support needs. The formal sources provided mostly financial and practical support, whereas the informal sources offered emotional and informational support. The barriers to access included the attitude of the staff and SOS adults and limited cultural skills of the care leavers. Recommendations for removing the barriers and improving social support for care leavers are offered in the final part of the study.  相似文献

A multiproduct translog cost function is estimated and used to calculate elasticities of factor substitution in the production of police services. The data come from Florida's municipal police departments and are for 1982–1983. It is found that substitution elasticities between any pair of inputs in police production are significantly different from unity. This result is inconsistent with the Cobb–Douglas production function—a functional form that has been extensively employed in empirical studies of police production.  相似文献
