Financial intermediation costs in low income countries: The role of regulatory,institutional, and macroeconomic factors

We analyze factors driving persistently higher financial intermediation costs in low-income countries (LICs) relative to emerging market (EM) country comparators. Using the net interest margin as a proxy for financial intermediation costs at the bank level, we find that within LICs a substantial part of the variation in interest margins can be explained by bank-specific factors: margins tend to increase with higher riskiness of credit portfolio, lower bank capitalization (or lower risk aversion), and smaller bank size. Overall, we find that concentrated market structures and lack of competition in LICs banking systems and institutional weaknesses constitute the key impediments preventing financial intermediation costs from declining. Our results provide strong evidence that policies aimed at fostering banking competition and strengthening institutional frameworks can reduce intermediation costs in LICs.     

Relating Macro-economic Efficiency to Financial Efficiency: A Comparison of Fifteen OECD Countries Over an Eighteen Year Period

This paper examines the role of the banking sector in the overall economic activity and its contribution to the convergence/divergence in fifteen OECD countries over the time period of 1980–1997. We resort to a non-parametric technique (DEA) and estimate a world wide macro-economic as well as a worldwide banking frontier. We find a very similar pattern in the evolution of banking and macro-economic efficiency. We further study the evolution of the macro-economic and banking productivity and discover, in both cases, convergence over time. Our first finding is that the performance of the banking sector helps to explain the overall economic performance. Our second finding is that the financial orientation of each country constitutes a relevant feature for the last mentioned explanation.     

A Cost System Approach to the Stochastic Directional Technology Distance Function with Undesirable Outputs: The Case of us Banks in 2001–2010

This paper offers a methodology to address the endogeneity of inputs in the directional technology distance function (DTDF)‐based formulation of banking technology which explicitly accommodates the presence of undesirable nonperforming loans—an inherent characteristic of the bank's production due to its exposure to credit risk. Specifically, we model nonperforming loans as an undesirable output in the bank's production process. Since the stochastic DTDF describing banking technology is likely to suffer from the endogeneity of inputs, we propose addressing this problem by considering a system consisting of the DTDF and the first‐order conditions from the bank's cost minimization problem. The first‐order conditions also allow us to identify the ‘cost‐optimal’ directional vector for the banking DTDF, thus eliminating the uncertainty associated with an ad hoc choice of the direction. We apply our cost system approach to the data on large US commercial banks for the 2001–2010 period, which we estimate via Bayesian Markov chain Monte Carlo methods subject to theoretical regularity conditions. We document dramatic distortions in banks' efficiency, productivity growth and scale elasticity estimates when the endogeneity of inputs is assumed away and/or the DTDF is fitted in an arbitrary direction.

ON THE SOURCES OF HETEROGENEITY IN BANKING EFFICIENCY LITERATURE

This study reviews the empirical literature on banking efficiency by conducting a meta‐regression analysis. The meta‐dataset consists of 1661 observations retrieved from 120 papers published over the period 2000–2014. While the role of study design and method‐specific characteristics of primary studies is evaluated, the focus concerns regulation in banking. The results are fourfold. First, parametric methods always yield lower levels of banking efficiency than non‐parametric studies. Second, banking efficiency is higher in studies using the value‐added approach rather than the intermediation method. Third, efficiency scores also depend on the journal's ranking and on the number of observations and variables used in the primary papers. Finally, regulation matters: primary papers focusing on countries with a liberalized banking industry provide higher values for efficiency scores.     

The effect of banking market structure on the volatility of growth of manufacturing sectors in developing countries

I explore the effect of banking concentration and banking competition on the volatility of the growth of value added of manufacturing sectors in the developing countries. In this paper, I bring together two strands of literature, one that discusses the effect of financial intermediation on volatility of growth and another one that discusses the effect of banking concentration and competition on credit access. Following the industrial organization literature, I look at the effect of banking competition and banking concentration on the volatility of manufacturing sectors separately. I find that banking concentration has a dampening effect on the volatility of growth of the industries. On the other hand, I find that as banking competition increases, the volatility of the growth of industries increases, also.     

Efficiency,growth and market power in the banking industry: New approach to efficient structure hypothesis

We extend the work of Homma, Tsutsui, and Uchida (2014) to provide empirical evidence on nexus of relationships in efficient structure (ES) hypothesis. In this framework, we test causality from cost efficiency to bank growth and then from bank growth to market concentration. We apply this approach to banking industry in Association of South East Asian (ASEAN) over the period of 1999–2014. The efficiency scores have been estimated by employing Slack Based Measurements Data Envelopment Analysis (SMB DEA). We apply Two-step system Generalized Method of Moments (GMM) and Panel Vector Auto Regression (PVAR) to account for endogeneity in estimation models. The results show that cost efficiency enables the banks to grow and obtain higher market share. The resultant growth then leads to higher market concentration/bank market power. There is also some evidence to support for quiet life (QL) hypothesis. Therefore, both ES and QL hypotheses may coexist in ASEAN banking industry.

Shadow Banking,Chinese Style

Shadow banks are broadly defined as entities which conduct credit intermediation outside the formal banking system. Poorly regulated, engaging in opaque forms of intermediation, deeply interconnected with the official banking system, and operating with implicit government guarantees, they pose a major source of systemic risk. Yet shadow banks provide an important service by channeling credit to excluded investors, and can complement the formal banking sector. What explains the rapid proliferation of shadow banks in China? How large are they and what forms do they take? What types of risks do they pose to the financial system? And how best can China utilise the services of shadow banks while at the same time ensuring that they do not create systemic risks for the financial system?     

Political regimes and bank interest margins

The political determinants of banks' profitability are yet to be fully explored in the political economy of finance literature. This article brings politics to the theoretical discussion and the empirical analysis of bank interest margins, arguing that differences in political regimes are crucial in accounting for variations in banking profits across countries. The paper argues that we should expect lower margins from financial intermediation in autocracies than in democracies because of an inherent credibility problem and a lack of oversight in the former. Limited by state-owned banks or regulations favoring cronies, the room for financial elites to develop independent political power to threaten the government should be lower in autocracies than in democracies. I test this hypothesis with nonparametric (matching) and parametric analyses, where the former is used to estimate the latter to lower model dependence. The results consistently show that banks' interest margins in autocracies are lower by some amount between -0.4 and -1.3. This association is also confirmed indirectly when we analyze the impact of banking competition. The existence of big banks in democracies is positively related to banks' profits from intermediation, while the opposite is true for autocracies.     

An expectancy-equity model of productive system performance

Although numerous behavioral variables (e.g., personality traits, incentives, nature of supervision) have documented relationships with quantity and quality of output, i.e., performance, in production systems, existing production and operations management models are dominated by technological variables. The article addresses three questions: 1. Which technological and behavioral variables influence productive system performance? 2. How do behavioral and technological variables interact? 3. Which variables are most important under different circumstances in determining performance?An expectancy-equity model, patterned on research by Lawler [22], presents proposed relationships among variables in production systems, which are classified along a continuum from high to low process predictability. Predominant determinants of performance in various types of systems (e.g., continuous process, job shop, R&D project) are considered in light of the model. Implications for designers and analysts of productive systems and for future research are discussed.     

Indirect Convertibility,Equity‐Based Banking and Financial Stability

Banking reform proposals put forward in the wake of the recent financial crisis maintain that equity‐based banking would be stable and would prevent bank runs. This article argues that complementing this form of banking with an indirect convertibility monetary standard and thereby dispensing with base money would enhance financial stability further. Banks would not hold a distinctive asset (base money) that would be called upon by customers at short notice, thereby removing the possibility of bank runs. No discrepancy in value between the two sides of a bank's balance sheet would arise as its assets (securitised loans) would be marked to market. Unlike other recent contributions, the intermediation model outlined here is not ‘limited purpose’ in nature as banks would not be restricted in the form of lending activity they can pursue. Common sources of banking and financial instability – liquidity risk, solvency risk, moral hazard – would be absent.     

MODELS OF BANKING INSTABILITY: A PARTIAL REVIEW OF THE LITERATURE

Abstract. This paper critically examines the theoretical literature on banking instability that has followed Diamond and Dybvig (1983). It explores the extent to which it (a) explains banking instability within a theoretical context in which financial intermediaries improve on unintermediated markets, and (b) justifies government involvement in the financial intermediation industry. It suggests that the literature has yet to provide a satisfactory theoretical basis for banking instability as such since the intermediaries which arise from it are peculiar mutual funds that bear little resemblance to real-world banks. In addition, the paper challenges the widespread belief that this literature provides a sound foundation for government involvement in the industry. It suggests that arguments for government intervention are open to objection on various grounds, the most important one being that they are inconsistent with the existence of properly motivated financial intermediation in these models.     

Market Concentration and Multifaceted Productive Efficiency

Developing the analytical framework of the decision making process of a possible entrant, a reduced form system equations model is estimated in order to examine the market concentration – productive efficiency relationship in an endogeneity context. Technical and scale efficiency estimates are obtained from an inter-industry stochastic production frontier using a panel dataset regarding the seven most energy intensive manufacturing industries in Greece over the period 1980–96. Several new versions of the concentration – efficiency relationship, may be derived from the alternatives of the entrant considering the possible conduct character of incumbents’ technical efficiency and excess capacity, which is depicted on their scale efficiency, on market concentration.     

The role of financial intermediaries in monetary policy transmission

The recent financial crisis has stimulated theoretical and empirical research on the propagation mechanisms underlying business cycles, in particular on the role of financial frictions. Many issues concerning the interactions between banking and monetary policy forced policy makers to redefine economic policies, and motivated macroeconomists to focus on the implications of financial intermediation constraints for asset price fluctuations, the behavior of non-financial firms, households, governments and in turn for real macroeconomic performance. This paper surveys research on the role of financial intermediaries and financial frictions in the transmission of monetary policy and discusses how to design both the new banking regulatory and supervisory structures and monetary policy in order to stabilize the economy. It also serves as an introduction to this special issue.     

Addressing the endogeneity dilemma in operations management research: Theoretical,empirical, and pragmatic considerations

In this paper, we examine the problem of endogeneity in the context of operations management research. Whereas the extant literature has focused primarily on the statistical aspect of the problem, a comprehensive treatment requires an examination of theoretical and pragmatic considerations as complements. The prevailing problem with the focus on statistical techniques is that the standards tend to be derived from idealizations: the correlation between a regressor and a disturbance term must be exactly zero, or the analysis will be invalid. In actual empirical research settings, such a knife-edge assumption can never be satisfied, indeed it cannot even be directly tested. Idealizations are useful in helping us understand what it would take to eliminate endogeneity, but when applied directly and unconditionally, they lead to unreasonable standards that may unnecessarily stifle substantive inquiry. We believe that it is far more productive and meaningful to ask: “What can we realistically expect empirical scientists to be able to achieve?” To this end, we cover and revisit some of the general technical material on endogeneity, paying special attention to the idiosyncrasies of operations management research and what could constitute reasonable criteria for addressing endogeneity in empirical operations management studies.     

Structural changes,competition and bank stability in Malaysia’s dual banking system

This paper assesses Malaysia’s competition landscape and its risk implications subsequent to conventional banking consolidation and Islamic banking penetration in the aftermath of the 1997/1998 Asian financial crisis. Employing a panel sample of conventional and Islamic commercial banks, it arrives at the following conclusions. First, the consolidation exercise, which has led to a significant reduction in the number of domestic commercial banks, has not stifled banking competition. Second, the paper provides empirical support for the competition-stability relationship, particularly for the conventional banking sector. Islamic banking sector risk appears to be neutral to market competition or market power, although there is limited evidence that it increases with overall market concentration. Finally, the analysis uncovers the risk-increasing effect of the Islamic banking market structure on the conventional banking sector. By contrast, conventional banking market concentration tends to reduce the credit risk of Islamic banks.     

Analysis of Intertemporal Efficiency Trends Using Rank Statistics With an Application Evaluating the Macro Economic Performance of OECD Nations

This paper presents two applications of rank statistics to evaluate efficiency performance trends using productive efficiency measures derived through various Data Envelopment Analysis (DEA) models. The paper starts with a discussion of the difficulties in obtaining consistent ranks from DEA efficiency ratings. Next, a procedure is proposed to identify intertemporal performance trends using any one of several possible efficiency measures. Another procedure is then developed to test the stability over time of the rank positions of the analyzed units. For each statistical procedure, a small numerical example involving DEA efficiency measures is provided to illustrate the proposed technique. Finally, the new procedures are applied to data reflecting the macro-economic performance of 17 OECD nations in 1979–1988. The outcomes of the application are discussed and contrasted with previous research in this area.     

Weight restrictions in DEA: misplaced emphasis?

Measuring productive efficiency is an important research strand within fields of economics, management science and operations research. One definition of efficiency is the proportional scaling needed for observations of inefficient units to be projected onto an efficient production function and another definition is a ratio index of weighted outputs on weighted inputs. When linear programming is used to estimate efficiency the two definitions give identical results due to the fundamental duality of linear programming. Empirical applications of DEA using linear programming showed a prevalence of zero weights leading to questioning the consequence for the efficiency score estimate based on the ratio definition. Early literature on weight restrictions is exclusively based on the ratio efficiency. It was stated that variables with zero weights had no influence on the efficiency score, in spite of the alleged importance of the variables. This has been one motivation for introducing restrictions on weights. Another empirical result was that often there were too many efficient units. This problem could also be overcome by introducing weight restrictions. Weight restrictions were said to introduce values for inputs and outputs. The paper makes a critical examinations of these claims based on defining efficiency relative to a frontier production function.     

How important can bank lending shocks be for economic fluctuations?

We analyze the quantitative importance of bank lending shocks on real activity fluctuations in Norway and the UK, using structural VARs estimated on quarterly data from 1988 to 2010. We find that an adverse bank lending shock causes output to contract, and that such shocks can account for a substantial share of output volatility. This suggests that financial intermediation is an important source of shocks. The empirical analysis comprises the Norwegian banking crisis (1988–1992) and the recent period of banking failures in the UK. However, the results are also non-trivial when omitting periods of systemic banking distress from the sample.
