Cost and profit efficiencies in transition banking: the case of new EU members

This paper analyses cost and profit efficiencies in commercial banking in the eight Central and Eastern European countries that became new members to the European Union. Common stochastic cost and profit frontiers with country-specific variables are employed in order to take into account macro-economic and financial sector conditions that vary over time and across countries. The impact of foreign ownership on performance is also examined. The results indicate a wide range of cost and profit inefficiency scores across countries and across different size groups. All banking systems in the sample display significant levels of cost and profit inefficiency and there does not seem to be any continuous improvement in performance over time. There is also some evidence that foreign banks perform, on average, better than domestic banks.

Testing the Purchasing Power Parity Hypothesis for the New Member and Candidate Countries of the European Union: Evidence from Lagrange Multiplier Unit Root Tests with Structural Breaks

This paper investigates the validity of purchasing power parity (PPP) for the eleven Central and East European transition countries and three market economy countries, Cyprus, Malta, and Turkey. Unlike previous studies on PPP, this study uses Lagrange multiplier (LM) unit root tests that incorporate structural breaks in the data series. The findings indicate that in cases of one and two structural breaks, for a U.S. dollar-based real exchange rate series, there is little evidence supporting the validity of PPP. For a deutsche mark-based real exchange rate series, for the cases of both one and two breaks, there is evidence of stationarity of real exchange rates for eight sample countries, which is consistent with PPP. The results also indicate that the estimated half-life of a shock to the real exchange rate ranges from 1.25 (15.05 months) to 2.72 (32.72 months) years across countries. The empirical findings may provide direction for policy makers to coordinate monetary policies for the process of European monetary integration.

Fisher Hypothesis Revisited: A Fractional Cointegration Analysis

This paper investigates the validity of the Fisher hypothesis using data from thirtythree developed and developing countries. Conventional cointegration tests do not provide strong evidence for a relation between nominal interest rates and inflation. Therefore, we use fractional cointegration analysis to test the long-run relationship between the two variables. The results indicate that a long-run relation between nominal interest rates and inflation does not appear for most countries in the sample when the conventional cointegration test is employed. However, fractional cointegration between the two variables is found for a large majority of countries, implying the validity of the Fisher hypothesis. The results also indicate that the equilibrium errors display long memory.

The impact of sudden changes on the persistence of volatility: evidence from the BRIC countries

This article analyses sudden changes of volatility in the stock markets of the BRIC countries (Brazil, Russia, India and China) using the iterated cumulative sums of squares algorithm for the period 1990 to 2007 and examines their impacts on the persistence of volatility. The results show that when endogenously determined sudden shifts in variance are taken into account in the Generalized Autoregressive Conditional Heteroscedasticity (GARCH) model, the estimated persistence in return volatility is reduced significantly in every return series. These results suggest that the findings of previous studies could have overestimated the degree of the persistence of volatility existing in the financial time series. These results have important policy implications for the financial market participants and policy makers.

Cost efficiency and scale economies in the Turkish insurance industry

This article examines the cost efficiency and scale economies of insurance firms in the Turkish insurance industry over a 15-year period, 1990–2004. Using the stochastic cost frontier model, cost efficiency scores and scale economies were estimated for each firm in the sample. The results show that mean cost inefficiencies range between 18.3 and 36.9% of total costs and they do not tend to decrease over time. On average, small firms are more cost efficient than large firms. Economies of scale appear present and significant for any class size. The results suggest that there is a substantial difference in scale economies between small and large insurance firms.

Efficiency and Risk in Latin American Banking: Explaining Resilience

Using an unbalanced panel of 272 commercial banks, we estimate cost and revenue efficiency scores for fifteen Latin American and Caribbean countries over the period 2001-8. Using Granger causality techniques, we find evidence that in the face of increased risk and lowered capital, banks have tended to improve cost efficiency. The results also indicate that cost efficiency is negatively related with revenue efficiency, both dynamically and across countries. Market concentration is related to greater revenue efficiency. In the absence of developed capital markets, competitive forces and strengthened regulation seem to be forcing cost-efficiency improvements. Banks with market power, however, seem to be able to pass on to customers the cost of raising capital buffers and provisioning for risk.

FINANCIAL STABILITY, COMPETITION AND EFFICIENCY IN LATIN AMERICAN AND CARIBBEAN BANKING

Using a sample of 272 commercial banks from fifteen Latin American countries for the period 2001–2008, we estimate cost and revenue efficiency scores, financial stability scores (Z-scores) and competition scores (Lerner indexes and Boone indicators) at the bank level. The Granger causality technique in dynamic panels is used to establish dynamic relationships among these variables. We find evidence that strongly supports the “quite life” hypothesis, while we also find partial support for causality running in the opposite direction. Moreover, the results suggest that more competition is conducive to greater financial stability (when the revenue efficiency score is used). Banks seem to achieve market power through better efficiency, leverage and earning ability. As size and complexity increase, however, agency problems and increasing risk-taking might start gaining momentum, generating inefficiency and fragility.

Technical Change in Banking: Evidence From Transition Countries

Abstract This paper investigates the effect of technical change on the costs of banking firms operating in 11 Central and Eastern European countries using Fourier‐flexible cost function specification for the period 1995–2002. A common cost frontier with country‐specific variables is employed in order to take into account macro‐economic and regulatory conditions that vary over country and time. Our findings suggest that the rate of reduction in costs resulting from technical change increased during the sample period. Banks operating in Hungary, Czech Republic and Poland benefited more from technical change than their counterparts. In terms of cost reduction, large banks benefited more from technical progress. This indicates that large banks are more able to change their optimal input mix in response to changes in technology.

Consolidation and Competition in the Banking Industries of the EU Member and Candidate Countries

This paper investigates competitive conditions in the banking markets of all EU member and candidate countries over the period 1995-2007. The Panzar and Rosse (1987) model is implemented on bank-level data. In particular, the unscaled revenue equation is employed to assess market structure. Country-specific empirical results suggest a wide variation in the competitive conditions of the banking systems in the sampled countries. Nineteen banking systems are characterized as monopolistically competitive, nine as monopolies or perfectly colluding oligopolies, and two as perfectly competitive over the sample period. This study also investigates whether competition conditions changed over the sample period, using 2001 as an endogenously determined break year. The empirical evidence reveals that banking systems became less competitive after that time.

Nominal and real convergence between the CEE countries and the EU: a fractional cointegration analysis

This paper examines the real and nominal convergence between the Central and Eastern European countries and the EU, using fractional cointegration analysis for the period 1980–2003. Fractional cointegration analysis is a flexible methodology, which allows for more subtle forms of mean reversion. The tests performed are those of Geweke and Porter-Hudak. The convergence processes are valid when macroeconomic time series used in the study are fractionally cointegrated. The results indicate that inflation and interest rates series of six sample countries are fractionally cointegrated with those of the EU. Therefore, nominal convergence has been achieved by some of the transition countries, but the equilibrium errors display long memory. Results also indicate that industrial outputs of most countries in the sample are not fractionally cointegrated with that of the EU. The results further indicate that both nominal and real convergence have been achieved only for Hungary.
