On information efficiency and financial stability

We study a simple model of an asset market with informed and non-informed agents. In the absence of non-informed agents, the market becomes information efficient when the number of traders with different private information is large enough. Upon introducing non-informed agents, we find that the latter contribute significantly to the trading activity if and only if the market is (nearly) information efficient. This suggests that information efficiency might be a necessary condition for bubble phenomena, induced by the behavior of non-informed traders, or conversely that throwing some sands in the gears of financial markets may curb the occurrence of bubbles.Comment: 14 pages, 2 figure

Banking efficiency and economic growth in the MENA region

This paper examines the nexus between cost efficiency and economic growth in the Middle East and North Africa region. We apply a causality analysis between cost efficiency and financial deepening using the Generalized Methods of Moments and our findings show a significant and positive causality and reverse relationship between financial deepening and banking productivity. We introduce a set of control variables associated with the long run growth and find an interesting interaction with banking productivity and financial deepening suggesting that efforts should be focusing on the investments’ efficiency and the increase of regulation to spur a more stable financial system and foster financial deepening in the future

Money, Financial Stability and Efficiency

Most analyses of banking crises assume that banks use real contracts. However, in practice contracts are nominal and this is what is assumed here. We consider a standard banking model with aggregate return risk, aggregate liquidity risk and idiosyncratic liquidity shocks. We show that, with non-contingent nominal deposit contracts, the first-best efficient allocation can be achieved in a decentralized banking system. What is required is that the central bank accommodates the demands of the private sector for fiat money. Variations in the price level allow full sharing of aggregate risks. An interbank market allows the sharing of idiosyncratic liquidity risk. In contrast, idiosyncratic (bank-specific) return risks cannot be shared using monetary policy alone; real transfers are needed.

The efficiency implications of financial conglomeration

This paper studies the competitive and efficiency implications of financial conglomeration driven by cost-efficiency gains in monitoring credit and insurance customers. The analysis shows that conglomeration is conducive to tougher competition in the credit market and increases profit in insurance. The aggregate profit in the financial sector does not increase, because the conglomerates pass the cost-efficiency gains on to the borrowers in full. More competitive market for financial services also reduces the aggregate risk in the financial markets, indicating that capital requirements in both sectors should be lower in the presence of financial conglomerates.financial conglomerates; banking; insurance; capital regulation

Microfinance institutions: financial sustainability and efficiency

The main objective of this research is to analyse the relationship between financial sustainability and efficiency of Microfinance Institutions (MFIs) in terms of outreach to the poor as well as the relation between gender and repayment in microfinance. The sample used is composed of all MFIs in the globe as reported to MixMarket. Our study covers the period 2000-2010. The study also investigates whether the current global financial crisis has had any effects on the issues we study. Our dataset is organised as a panel dataset given that we have multiple observations on the same economic units and a number of periods over time. The estimation techniques are based on the fixed-effects (FE) and random-effects (RE) models. However we use the Hausman test in order to make a choice between FE and RE approaches. Our results show that FE models perform better that RE models through all the period of analysis. For the whole period of analysis results show that MFIs focusing on female clients, are characterized by a greater size of loans provided. On the other hand, we also find that the credit risk in microfinance institutions increases as the number of female clients raise

The efficiency in Thai financial sector after the financial crisis

This study aims to investigate the efficiency in Thai financial sector after the financial crisis (1998 – 2004) by looking at the total factor productivity (TFP) growth. Furthermore, the study also investigate the efficiency in commercial bank sector, finance and securities company sector and insurance company sector, and the efficiency in domestic and foreign financial companies. Based on the sample of 12 commercial banks, 13 finance and securities companies and 20 insurance companies listed on the Stock Exchange of Thailand (SET) over the period of 1998 – 2204, our finding reveals that the efficiency in Thai financial sector, commercial bank sector and finance and securities company sector was diminishing over the period of 1998 – 2004, while the efficiency in insurance company sector remained unchanged over the same period. However, the sharp decrease in efficiency in these three sectors occurred only over the period of 1998 – 1999, while the efficiency was decreasing very slightly over the period of 1999 – 2004. The study also suggests that, in overall, domestic financial companies are more efficient than foreign ones. Domestic finance and securities companies are also more efficient than foreign ones, whereas domestic and foreign commercial banks are not different in efficiency. Moreover, domestic and foreign insurance companies are not different in efficiency as well.efficiency; productivity; financial sector; total factor productivity

The efficiency of financial markets with high inflation

In a two period general equilibrium model with incomplete asset markets, it is shown that the contraction of nominal financial markets that occurs during high inflations can result from the variability of the future rate of inflation and from large bankruptcy costs. If the probability that inflation in the future will be high is sufficiently large, then, for a generic set of endowments, an increase in the variability of future prices reduces the utility possibilities set. In economies with only nominal assets more variable future prices lead to a Pareto fall in social welfare

Risk-return Efficiency, Financial Distress Risk, and Bank Financial Strength Ratings

This paper investigates whether there is any consistency between banks' financial strength ratings (bank rating) and their risk-return profiles. It is expected that banks with high ratings tend to earn high expected returns for the risks they assume and thereby have a low probability of experiencing financial distress. Bank ratings, a measure of a bank's intrinsic safety and soundness, should therefore be able to capture the bank's ability to manage financial distress while achieving risk-return efficiency. We first estimate the expected returns, risks, and financial distress risk proxy (the inverse z-score), then apply the stochastic frontier analysis (SFA) to obtain the risk-return efficiency score for each bank, and finally conduct ordered logit regressions of bank ratings on estimated risks, risk-return efficiency, and the inverse z-score by controlling for other variables related to each bank's operating environment. We find that banks with a higher efficiency score on average tend to obtain favorable ratings. It appears that rating agencies generally encourage banks to trade expected returns for reduced risks, suggesting that these ratings are generally consistent with banks' risk-return profiles.bank ratings; risk-return efficiency; stochastic frontier analysis

Efficiency of Insurance Firms with Endogenous Risk Management and Financial Intermediation Activities

Risk management is now present in many economic sectors. This paper investigates the role of risk management in creating value for financial institutions by analyzing U.S. property-liability insurers. Property-liability insurers are financial intermediaries whose primary roles in the economy are risk pooling and risk bearing. The risk pooling and risk bearing functions performed by insurers are the primary determinants of the need for risk management. The main goal of this paper is to test how risk management and financial intermediation activities create value for insurers by enhancing economic efficiency. Insurer cost efficiency is measured relative to an econometric cost function. Since the prices of risk management and financial intermediation services are not observable, we consider these two activities as intermediate outputs and estimate their shadow prices. The shadow prices isolate the contributions of risk management and financial intermediation to insurer cost efficiency. The econometric results show that both activities significantly increase the efficiency of the property-liability insurance industry.Risk management, US property-liability insurer, risk pooling, financial intermediation, economic efficiency, intermediate output, shadow price, cost function, translog approximation

Measuring efficiency of the Farm Credit System

The paper measures the U.S. Farm Credit System’s technical efficiency from 2000 to 2009 using a stochastic frontier production function model with quarterly unbalanced panel data. The paper's results suggest that the FCS has not efficiently utilized their inputs. On an average, the system realizes only 9.7% of their technical abilities in raising their loans, leases and investment. The efficiency of the whole system is estimated to slightly increase over time even during financial crisis period from 2007. Among the system, a significant difference in efficiency between the 5 Banks and the Associations has been found. On average, the Banks have higher technical efficiency of 62.4% compared to that of 7.7% of the associations. The efficiency of the latter increases by a small rate over time during 2004-2009 periods while efficiency of the former is more time-varying and experiences the opposite pattern. No evidence about the impact of financial crisis on the system efficiency was found.Farm Credit System, agricultural lenders, technical efficiency, financial crisis, stochastic frontier production function, financial reform, Agricultural Finance,
