Banking Sector Development and Energy Consumption in Nigeria: Exploring the Causal Relationship and its Implications

This study examines the causal relationship between banking sector development and energy consumption in Nigeria over the period 1971–2013 incorporating crude oil price and indicators of economic performance. An autoregressive distributed lag bounds testing approach to cointegration provides evidence of long‐run relationship among the variables. The long‐run and short‐run estimates suggest that a non‐linear inverted U‐shaped relationship exists between banking sector development and energy consumption in Nigeria, indicating that initially, energy consumption increases as the banking sector develops and then declines as the banking sector matures to generate efficiency in energy consumption. In addition, this study explores the direction of causality between the variables using the Toda–Yamamoto Granger causality test procedure. The results suggest that a unidirectional causality runs from crude oil price to banking sector development, from banking sector development to energy consumption and from energy consumption to economic growth. It may therefore be necessary for policy makers in Nigeria to incorporate banking sector development in the energy and sustainable economic policies.     

Banking Sector Fragility and the Transmission of Currency Crises

We assess whether, complementary to trade and financial linkages, banking sector fragility helps explain the transmission of currency crises. We attempt to strike a balance between the precision of measurement of banking sector fragility on the one hand and its consistent measurement across various crisis episodes on the other. We find that while the role of trade and financial linkages is robust over time, the independent role of banking sector fragility is rather weak and unstable across crisis episodes. Consequently it is difficult to extrapolate observed banking fragility transmission channels from one crisis to another. As a corollary we cannot conclude that during future crisis episodes economies characterized by fragile banking sectors are more prone to crisis transmission.     

ECONOMIC GROWTH, CONVERGENCE CLUBS, AND THE ROLE OF FINANCIAL DEVELOPMENT

This paper aims to show and test the existence of a povertytrap linked to the development of the banking sector. Our theoreticalmodel exhibits multiple steady state equilibria due to a reciprocalexternality between the banking sector and the real sector.Growth in the real sector causes the financial market to expand,thereby increasing banking competition and efficiency. In return,the development of the banking sector raises the net yield onsavings and enhances capital accumulation and growth. The aimof our econometric tests is to check the existence of multiplesteady states associated with financial and educational development.     

Testing the Validity of the Simultaneous Openness Hypothesis in Nigeria (1990–2015)

Since the seminal paper by Rajan and Zingales in 2003, a plethora of studies have been motivated to establish whether the simultaneous opening of trade and capital borders leads to financial sector development. We test whether the simultaneous openness hypothesis is valid for Nigeria, with a focus on the banking sector and stock market. Using annual data from 1990 to 2015 and an instrumental variable regression estimation technique, we show that the simultaneous increase of trade and financial openness limits banking sector and stock market development. Thus, there is no empirical evidence to validate the simultaneous openness hypothesis in Nigeria. It also shows that trade openness is more beneficial for banking sector and stock market development in Nigeria than financial openness.     

Understanding the Growth of African Financial Markets*

Abstract: This paper examines empirically the determinants of financial market development in Africa with an emphasis on banking systems and stock markets. The results show that income level, creditor rights protection, financial repression, and political risk are the main determinants of banking sector development in Africa, and that stock market liquidity, domestic savings, banking sector development, and political risk are the main determinants of stock market development. We also find that liberalizing the capital account promotes financial market development only in countries with high incomes, well‐developed institutions, or both. The powerful impacts of political risk on both banking sector and stock market development suggest that resolution of political risk may be important to the development of African financial markets.     

跨境资本周期性波动对中国银行部门的风险溢出机制分析

本文从周期角度出发,构建结构模型和双重△CoVaR模型,探究跨境负债和资产的扩张或收缩对银行部门的风险溢出机制。结果显示:第一,跨境资本周期性波动对银行部门具有显著的风险溢出效应,跨境负债波动的溢出效应强于跨境资产。第二,跨境资本周期性波动通过影响中小银行风险承担和风险实现以及大型银行的风险放大作用影响银行部门。特别地,股份制银行在受冲击和风险放大方面均具有重要作用。第三,跨境资本扩张带来的风险承担会显著提高未来银行业系统性风险实现水平。本文为提高跨境资本管理质量提供了科学依据。     

中国外资银行服务贸易自由化的经济影响研究——基于可计算一般均衡SIC-GE模型的定量分析

本文利用2005～2009年以来我国逐渐取消外资银行进入壁垒的实际数据,通过设立银行业收益和成本方程发现并估算出消除壁垒带来的两方面行业直接效应,即外资银行服务价格水平下降1.9%和国内银行业经济效率改进1.8%。在此基础上利用国家信息中心可计算一般均衡模型(SIC-GE)就壁垒消除对整个经济体的影响进行了系统评估。测算结果表明,两个直接效应中,改进国内银行业经济效率的经济影响是主要的;从宏观层面上看,短期内能够带来就业和GDP相对基准情景增长,同时居民消费、投资和出口有所增长。进口随着国内需求的扩张略有增长,净出口明显扩大。总体上,研究结果表明,2005年以来我国逐渐取消外资银行贸易壁垒是一项较为有效的政策举措,具有较好的示范作用。     

Competitive Conditions in the Tanzanian Commercial Banking Industry

Abstract: Since 1991, Tanzania has made important improvements in reforming its financial sector, dismantling the state‐dominated banking sector and allowing foreign bank entry. Despite this, the banking industry is still concentrated with low accessibility to financial services. Large foreign banks dominate the financial landscape, preventing competitive dynamism to permeate the sector. This paper analyses the competitive nature of the Tanzanian banking industry from 2004 to 2008. Utilizing a rich bank level data set, we employ the Panzar–Rosse methodology to compute the competitive index, taking into account risk, efficiency, regulatory and macroeconomic factors. The results show that banks in Tanzania earned their income under conditions of oligopolistic conduct. Moreover, the competitive index derived from an interest revenue equation was not significantly different from that obtained using an aggregate revenue measure. This suggests that the degree of contestability from traditional intermediation activities approximates overall bank behaviour. The overall message is that greater market contestability can be achieved by adopting measures aimed at stimulating competitiveness in the banking sector, including consolidating gains on the macroeconomic front and allowing more foreign bank entry so as to increase the spread of banking services.

Banking in the Shadows: A Comparative Study of China and India

In recent years there has been increasing interest in the rise of shadow banking in China and India. In this paper, we aim to get a better understanding of the differences in trends and investigate the factors leading to the increase of shadow banking in these two major emerging economies. We find that financial exclusion is a common factor leading to the growth of shadow banking in both countries. While financial reform has taken place in India, financially repressive policies still prevail in China. Although several regulatory measures have been adopted in India and China, the size of the shadow banking sector in these two countries remains underestimated. Thus, streamlining and enhancing data collection is a key priority for both nations. We argue that regulation in both countries should be more activity focused (specific field in which a shadow bank is focused on) rather than sector or entity based, and it should be at par with banks. The shadow banks provide last mile connectivity to remote, distant, and ignored segments of the population not serviced by the formal financial sector. As this enhances financial inclusion, a balanced approach is required keeping in view both costs and benefits of the shadow banking system.     

Offshore Banking and Economic Growth: A Cross-Country Analysis

Abstract

This paper investigates the effect of an offshore banking sector on economic growth. For this purpose, we specified a growth equation for the 41 countries that report their external positions to the Bank for International Settlements and evaluated how the size of an offshore banking sector, measured by external assets or liabilities contributed to the countries' per capita income growth. The distinctive features of this paper are that compared to previous studies, we used more comprehensive data and more flexible empirical specifications to investigate the effects of offshore banking. We find that the size of an offshore banking sector and economic growth have a nonlinear relationship, and the growth effect tends to increase as the scale of offshore banking increases.     

外资银行进入对东道国银行业效率的影响——东欧国家的经验与中国的实践

东欧国家银行改革的经验表明,外资银行进入能普遍提高东道国银行业的效率。但是,外资银行发挥积极作用亦取决于一定条件:东道国经济发展水平、银行业规模及发育程度、监管水平、银行业的改革路径和引资方式。本文在综述东欧国家银行业改革经验的基础上,提出中国银行业改革的7个命题,并用中国24家银行1999～2006年间的数据构建模型进行检验,最后得出结论:短期内外资银行进入会导致东道国银行业利润水平下降、风险管理水平上升,在中国的背景下可以认定这是外资银行积极作用的发挥;外资银行机构数量的增加和持股比重的上升都能刺激中国银行业效率的改进,但是外资银行持股比重的影响更具普遍性;不同类型银行对外资银行进入的反应存在差异,国有商业银行反应比较迟钝,而股份制和城市商业银行反应比较迅速。

Reform of the Japanese banking system

Japan has experienced a decade-long economic stagnation with a distressed banking sector in the 1990s. The absence of a credit culture to rigorously assess and price credit risks of borrowers, aggravated by weak prudential and supervisory frameworks, in the 1980s, the collapse of the asset price bubble in the early 1990s, and the lack of decisive, comprehensive strategy to address the banking sector problem at an early stage were largely responsible for the emergence of banking sector problems. All of these allowed a systemic banking crisis to emerge in 1997–98 and a large output loss during 1998–2002. The crisis ultimately prompted the government to take a more aggressive policy to tackle the problem. Considerable progress has been made since then on banking sector stabilization, restructuring, and consolidation. The regulatory and supervisory framework has been strengthened in a way consistent with an increasingly market-oriented, globalized environment. As a result, the worst is over in the Japanese banking system, setting the stage for sustained economic recovery. Though bank capital may still be inadequate, safety nets are in place, and credit allocation has been made more rational. Remaining risks are limited to regional and smaller institutions that are vulnerable to weak, local economic conditions and hikes of the long-term interest rate.

Forecasting the optimal structure of the Russian banking system

The systemic approach is used to substantiate the conclusion that in sustainable banking systems, the number of banks and the structure of the banking sector depend on the amount of the dominant bank’s assets. It is shown that if Sberbank’s share in the Russian banking system’s total asset is 0.26, the number of banks in it should decrease several times and stay within the range of 55–165.     

Trend analysis of Russian Banks’ qualitative composition

The paper offers an approach to the typification of homogeneous groups of banks, using some revenue source dominance criterion applied to Russia’s banking sector and a database for the 2008–2011 period. The authors define the major trends in changes in the structure of Russia’s banking sector under the conditions of crisis-related phenomena.

A Descriptive Model of Banking and Aggregate Demand

We integrate a banking sector into an accessible macroeconomic framework, which then provides new insights on developments around the Global Financial Crisis. The analysis shows that growth of banking sector money supply may help explain the secular decline in long-term interest rates before the crisis. A new bank funding channel of monetary transmission clarifies why increases in central bank policy rates could not reverse this trend. Our analysis highlights the distinction between the zero lower bound and the liquidity trap, and shows that bank recapitalizations can be more effective than fiscal expansions in restoring aggregate demand after a banking crisis.     

Asian Financial Crisis and the Evolution of Korean Banks Efficiency: A DEA Approach

Abstract

In the mid-1990s, the East Asian countries experienced severe financial crisis that were followed by deep economic downturns. A variety of methodologies have been used to understand the nature of the Asian financial crisis. However, the impact of the 1997 Asian financial crisis on the efficiency of the financial industry has yet to be critically examined. By employing the Data Envelopment Analysis (DEA) approach the present study attempts to examine for the first time the impact of the 1997 Asian financial crisis on the efficiency of the Korean banking sector. The study focuses on three major approaches, namely, intermediation, value added, and operating approaches. The results clearly bring forth the high degree of inefficiency in the Korean banking sector, particularly a year after the Asian financial crisis. We find that the Korean banking sector has consistently exhibit higher technical efficiency levels under value added approach, while technical efficiency seems to be lowest under intermediation approach.     

Changes in services trade barriers in banking and their impact: the case of the ASEAN+3

Although there has been extensive research on the ASEAN+3 countries, which reveals a synchronisation of economic policies, including exchange rate management policies, research on the regional pattern of trade policies in the banking sector is limited. We evaluate the trade barriers in banking and their evolution, using data from three sequential surveys conducted by the World Bank and surveys by other international organisations. We find that the country dispersions in trade‐restricting policies are stable over time. Moreover, we find no evidence of moves in the direction of liberalisation in the sector. The economic modelling undertaken provides an indication of the real income gains and the cost increases of the policies adopted.
