ABSTRACT

This paper is an empirical extension aimed at investigating the relationships between the indicators of the financial superstructure and its intermediation environments; and especially how the former responds to the effects of the latter. Intermediation-environmental models patterned after multivariate regression, causality, and partial adjustment models of both linear and log-linear formulations were estimated and analyzed. The results reveal that three environments: socio-political, regulatory, and international finance-exerted significant effects on the intermediation function of the superstructure. Previous intermediation successes ginger up current performance. In the long run, the effects of the environmental factors on the intermediation function of the superstructure, in whatever direction, more than quadruples. In any given year, the Nigerian financial superstructure attains only about 21.9% of desired (optimal) FIR. Given this, it would take about 4-1/2 years for it to adjust its intermediation operations (FIR), in light of the effects of environmental factors, to optimal levels in order to significantly impact the economy as desired. Some consistent behavioral traits were identified from the results to include: the precepts of potential maximization, profit maximization, accommodation principles, survival and cost-minimization principles, and the neutrality axiom.  相似文献

This paper, based on fieldwork results, explores traditional management systems (TMS) in the arid zone fisheries of north-eastern Nigeria with particular reference to their impact on rural poverty. The first section provides a historical background by tracing the evolution of the TMS since the nineteenth century, with reference to government policy on fisheries management and poverty alleviation. The second gives an overview of TMS, including definitions, distribution, principal objectives, regulatory mechanisms and the impact of TMS on the performance of the fisheries and on the livelihoods of rural people. The third considers the perceptions and attitudes of the fishing communities with regards to the fisheries and TMS. The paper concludes, paradoxically, that while TMS provide a basis for the sustainable livelihoods of many fishing people, they also reflect and enforce the social positions of the rich and powerful members of society who oversee them, at the expense of the poor. In the future, poverty alleviation in fisheries will need to incorporate both sectoral and non-sectoral strategies – dealing with the existing 'paradox of TMS' by encouraging appropriate institutional changes and community development, and recognizing the importance of employment creation in other sectors of the economy as a source of alternative income.  相似文献

We analyse the potential economic impacts of avian influenza (AI) in Nigeria, using a spatial equilibrium simulation model. Depending on the size of the affected areas, the direct impact of the spread of AI along the two major migratory bird flyways would be a loss of about 4% of national chicken production. However, the indirect effect – consumers’ reluctance to consume poultry if AI is detected, causing a decline in chicken prices – is generally larger than the direct effect in our simulation. We estimate that Nigerian chicken production would fall by 21% and chicken farmers would lose US$250 million of revenue if the worst‐case scenario occurs. The negative impact would be unevenly distributed in the country, and some states and districts would be seriously affected. The study shows that, while most attention has focused on preventing a global influenza pandemic, preventive measures are also needed at the national, regional and local levels, because AI could potentially have a major negative impact on the poultry industry and the livelihood of smallholder farmers in many regions in West Africa.  相似文献

This study examines voluntary disclosure practices amongst listed companies in Nigeria. Results from univariate and multivariate analyses of 52 listed companies suggest an average voluntary disclosure of 44% based on modified Meek, Roberts and Gray (1995) disclosure index comprising 24 disclosure items. The study found significant positive relationship between voluntary disclosure and firm size, measured as the natural logarithm of total asset. The study documents significant positive relationship between market-based definition of firm performance and voluntary disclosure. The study also found significant negative relationship between percentage of block share ownership and percentage of managerial share with firm disclosures. The study has important implication for both individual and institutional investors globally, regulators and policy makers in developing economies.  相似文献

This article considers the application of green revolution strategies in Nigeria. The authors discuss the background issues and the genesis of the green revolution before turning to the specific experiences of countries in Indo-Pakistan. The prospects for accelerated agricultural development in Nigeria brought about by green revolution technologies is considered. The authors conclude that the case of Nigeria is conceptually different to that of Asian countries but, with careful planning, green revolution technologies can contribute to sustained agricultural development in Nigeria.  相似文献

The study assessed poverty in rural areas of Ogun State, Nigeria through the food energy (calorie) intake approach. A sample of 60 households (comprising of 346 members) were selected using a multistage sampling technique and were interviewed with the aid of well‐structured questionnaire. Data were analysed using nutrient estimation techniques, cost of calorie method and poverty index. The estimated food poverty line was 64.72 naira. The incidence, intensity and severity of poverty were consistently higher among female‐headed households and households that lack access to credit facilities with values 0.290, 0.359, 0.160 and 0.313, 0.371, 0.160 for the poverty measures respectively. Incidence of poverty reduces with educational level and age of household heads, but the corresponding intensity and severity were higher for households whose heads are between 46‐ and 55‐year brackets and those who have secondary school education. All measures of poverty decline with farm size. Multipronged strategies involving improvement of educational level of household heads, improved access to agricultural land and credit facilities, as well as fair distribution of resources towards women, among others, are recommended for poverty and hunger reduction and for sustained agricultural production.  相似文献

This paper critiques the emergence of Dangote Cement as the dominant player in cement manufacturing in Nigeria. It argues that the changed economic environment General Obasanjo met when he became president of Nigeria for a second time in 1999 made it difficult for him to continue the nationalisation policies and the expansion of government involvement in several spheres of economic activity that he helped to promote in the 1970s. The realisation that this strategy, which created numerous crony capitalists, was unsustainable resulted in Obasanjo allying with Dangote and promulgating the Backward Integration Programme (BIP) for the local cement industry. This made it possible for Dangote to risk aggressive investment in the capital-intensive cement production business. This strategy achieved public good by rapidly making Nigeria, an oil rent- and import-dependent economy with enormous limestone reserves, self-sufficient in cement production.  相似文献

This article excavates the debate that unfolded during the 1980s between Jacques Rancière and Pierre Bourdieu to shed light on the theoretical divide that still cuts across the field of urban studies today. Looking at contemporary Rancièrian scholarship through a Bourdieusian lens, it points to their main theoretical shortcomings and reasserts the value of relational, field‐based and empirically grounded approaches to urban politics. At the same time, this article engages seriously Rancière's critique of Bourdieu's failure to account for space in order to question the territoriality inherent to the notion of field. We put this theoretical discussion to the test of Lagos's garbage. Drawing on an ethnographic study conducted in Lagos from 2015 to 2016, we propose analyzing the process of spatialization of the field of local representation by looking at the ways solid waste—here conceived as a political opportunity—is mobilized by different actors. We argue that the deployment of a waste infrastructure in Lagos is congruent with a relative disinvestment in practices of territorial control that reshapes the structure of local representation, reconfiguring the ‘stage’ on which politics is played out in the Nigerian metropolis.  相似文献

The study examines Nigeria's business cycles between October 1998 and October 2017 and ascertains the importance of general elections cycles in engendering cyclical fluctuations in different measures of business cycles. A framework based on political business cycles theory was estimated with a dynamic Markov‐switching regression technique. The study finds that election cycles are adequate in predicting cycles in food prices, non‐farm prices, exports, and imports in Nigeria while a significant effect of election cycles on the stock market, general price level, and exchange rate could not be established. The study concludes that cycles in food, non‐farm prices, imports, and exports can be predicted by future general elections while re‐election seeking behaviour of politicians lacks the power to influence stock market performance and exchange rate in Nigeria. Hence, artificial business cycles that result primarily from politicians manipulating certain fiscal tools targeted at stimulating the economy only to increase the re‐election chances could be minimized if monetary and fiscal institutions are strong, effective, and truly independent. This will ensure that policies are not manipulated between elections by politicians but are well targeted at achieving a set of long‐term developmental goals.  相似文献
