Public sector efficiency in transition and beyond: evidence from Czech local governments

This article provides the first comparison of public sector efficiency in and beyond transition. We compare the comprehensive efficiency scores of 202 local governments in the Czech Republic in the transition period of 1995–1998 and the post-transition period of 2005–2008 and identify the period-specific determinants of local government efficiency. We observe convergence to the best practice frontier but also a growing efficiency gap between small and large governments. In both periods, municipal size and the main fiscal variables qualitatively affect efficiency in the same direction and in line with the fiscal stress hypothesis. Left-wing ideology is only robustly associated with cost inefficiency in the transition period. The geographic distances begin to matter for efficiency only in the post-transition period.     

Stability analysis and efficiency determinants: empirical evidence

Efficiency determinants analysis is a main contemporary component in the productive efficiency literature. Two-stage data envelopment analysis (DEA) procedure supposed a turning point in the methodology as the significance of a certain exogenous factor can provide policymakers with accurate information for future strategic decisions, but a deeper scrutiny into the importance of each factor remains unsettled. This article provides a novelty theoretical extension and empirical application for the two-stage DEA bootstrap procedure. We define the stability coefficient (SC) whose magnitude reveals the effect of each exogenous factor in the efficiency estimates. We present empirical evidence to examine the hypothesis that the efficiency of the 17 Spanish tourism regions for the average period data 2005–2013 is determined by a group of contextual variables, illustrating how the SCs strengthen knowledge concerning the significance of each potential attractor. The results help us to classify the significant attractors into strong and weak, accordingly enhancing the public or private decision process, and henceforth avoiding the wastefulness of decision-making units spending.     

Retail‐bank efficiency: Nonstandard goals and environmental determinants

This paper analyzes technical and scale efficiency of Austrian savings and cooperative banks. Non‐profit objectives are also considered with respect to input–output choice, which contributes to adequate performance measurements for alternative banks. Efficiency score estimates obtained via Data Envelopment Analysis (DEA) reveal considerable potential for improvement in terms of intermediation efficiency. Several environmental determinants prove significant, but the cumulative predictive content of exogenous factors is rather modest. Bank efficiency improves in both underdeveloped and prosperous markets, while increased rival size and distance appear to be detriments to efficiency. A concluding discussion of confounding factors reveals the managerial, stakeholder, and policy implications of the results.     

An analysis of the impact of unionization on efficiency: evidence from a meta-frontier analysis

This article examines the impact of unions on the efficiency of establishments in the manufacturing industry by comparing the results from two different empirical strategies: stochastic frontier analysis (SFA) and meta-frontier analysis (MFA). While SFA concludes that union establishments show higher technological efficiency, the results are the opposite when estimating production functions with MFA. In SFA, unionized establishments appear to be more efficient because they remain closer to their own production frontier; however, in MFA – where groups with heterogeneous technology can be compared – we find that nonunionized establishments are more efficient because they are closer to the meta-frontier than their unionized counterparts.     

The effects of agglomeration economies on technical efficiency of manufacturing firms: evidence from Indonesia

This article examines the effects of agglomeration economies and industrial structure upon firm-level technical efficiency in the Indonesian manufacturing industry over the period 2004–2009. A stochastic production frontier and three channels of agglomeration economies consisting of specialization, diversity and competition are used. The empirical results show that the effects of specialization and diversity upon firm-level technical efficiency are positive and negative, respectively, indicating that specialization is more favourable than diversity for stimulating firms’ technical efficiency. Competition has a positive sign, showing that region with high levels of competition tend to be more conducive in accelerating firm-level technical efficiency. In terms of firm location, both dummy for urban region and industrial complex turn out to be positive, indicating that firms located in both areas are experienced higher technical efficiency. Both firm size and age also have positive effect upon technical efficiency.     

Financial liberalization,financial regulation and bank efficiency: a multi-country analysis

This article investigates the impact of financial reforms on bank efficiency. More specifically, we distinguish between two different types of financial reforms, i.e. financial liberalization measures and measures of the quality of bank regulation and supervision (i.e. financial regulation), and study their relationship to bank efficiency separately. Moreover, we analyse whether the impact of financial liberalization on bank efficiency is conditional on the quality of regulation and supervision of the banking system. We apply stochastic frontier analysis to calculate bank efficiency at the individual bank level and use a new and detailed database that measures different aspects of financial reforms. The data-set consists of 87 312 bank-year observations covering 61 countries for the period 1996–2005. Overall, we show that the impact of financial liberalization policies on bank efficiency is conditional on the extent to which bank regulation and supervision has been adopted and developed.     

Financing constraints and investment efficiency: evidence from a panel of Canadian forest firms

This article examines the financial constraint of 18 listed Canadian forest firms between 2000 and 2014 following the stochastic frontier approach. Empirical results support the observation that Canadian forest firms have a strong dependence of using both equity financing and debt financing as the coefficients of both equity and debt financing mean functions are significant at 1% level. The distribution of investment efficiency index (IEI) of all 18 firms demonstrates a loss of around 40% of the rate of investment due to financing constraints. Regional analysis demonstrates that the time-varying patters of IEI of three provinces are significantly different.     

Efficiency,heterogeneity and cost function analysis: empirical evidence from pathology services in the National Health Service in England

Pathology services are increasingly recognized as key to effective healthcare delivery – underpinning diagnosis, long-term disease management and research. To the extent that pathology services affect a patient’s treatment pathway, significant healthcare costs are influenced directly by the performance of these services. Given pressures on the UK Department of Health to make efficiency savings and that little is known about the efficiency of pathology laboratories, this area offers unlocked potential for efficiency gains. We adopt a time varying inefficiency model, with laboratory-specific time paths for inefficiency, to identify potential savings in pathology services based on a panel of 57 English laboratories over a 5 year period. We apply a range of approaches to account for observable and unobservable heterogeneity between laboratories. We find potential efficiency savings of 13% in pathology services in this sample, which implies the potential for an annual saving of £390m in pathology across the NHS. Our study also provides valuable insights into the impact of a range of factors influencing laboratory costs.     

Corporate governance and efficiency in banking: evidence from emerging economies

ABSTRACT

This article investigates the impact of corporate governance on bank efficiency across a sample of 139 commercial banks from 17 countries of Central and Eastern Europe during the period 2005–2012. Data on governance characteristics are hand-collected from banks’ reports. The empirical findings indicate that implementing rigorous corporate governance structures is associated with higher costs for banks and a lower level of efficiency. However, during the crisis, a tight governance mechanism significantly increases banks’ cost and technical efficiencies. We also show that prudent risk management is associated with both higher cost and technical efficiency for more capitalized banks, while rigid supervisory boards are linked with greater technical efficiency for more capitalized banks.     

Determinants of bank cost efficiency in transition economies: evidence for Latin America,Central and Eastern Europe and South-East Asia

In this study, we adopt Wang’s (2002) heteroscedastic stochastic frontier model, which allows us to investigate bank cost efficiency and to measure the marginal effects of some variables on both the level and the variability of inefficiency. In recent years, the financial crisis has significantly affected the banking systems of the transition countries. Hence, the efficiency is of major importance for the stability of the banks. Regarding the determinants of efficiency, we find evidence that banks that follow a more cautious strategy, characterized by lower risk appetite and average expectations on profitability, have higher cost efficiency. We also find that traditional deposit-taking and loan-making still remain the most efficient activity of the banks. Additionally, the results showed that a higher Gross Domestic Product growth rate implies an increase in the inefficiency level, indicating an unsustainable bank management behaviour, which in periods of economic growth adopts policies that can generate inefficiency in order to gain market share and to obtain higher bonuses. Country cost efficiency results show significant differences. The banking systems in transition countries in South Eastern Asia appear to have a higher cost efficiency level. Also, the effects of the financial crisis were less significant in this region.     

Production Efficiency in the South African Banking Sector: A Stochastic Analysis

Econometric estimates of the level of efficiency at bank branches are likely to provide detailed insight into the overall level of efficiency in banking. Therefore this paper uses Bayesian stochastic frontier analysis to assess the production efficiency of 61 bank branches in the nine provinces of the Republic of South Africa. We find that every branch is operating at increasing returns to scale and that the level of production efficiency of bank branches is lower than it could be. We also find that at current levels of output, on average, bank branches can reduce their costs by about 17% if they improve the level of efficiency. In addition, we find that Gauteng Province has the lowest average level of returns to scale, while the Free State Province has the highest average level of the nine provinces. In addition, via estimates of the posterior mean for shares and price elasticities, we find that the price of capital is the largest predicted proportion of costs. These findings suggest that bank branches could also obtain cost reductions by increasing the level of output. Regulatory policy reforms and competitive incentives to enable banks to meet this objective should be encouraged.     

Market efficiency and continuous information arrival: evidence from prediction markets

Two regularities in financial economics are that prices underreact to news events and that they display short term momentum. This article tests for the presence of these regularities in prediction markets offered by the betting exchange Betfair on the 2008 Ryder Cup Golf Competition. Betfair offered in play prediction markets on the individual match play pairings and on the Cup result, with trading being virtually continuous in all markets. Modelled probabilities of the Cup result were updated continuously using trades in the individual match play pairings. These probabilities were then compared with the probabilities of the Cup result implied by odds in that market. The odds in the market for the Cup result underreact to both good and bad news that is provided by changes in the odds in the markets for the individual pairings. Further, these modelled probabilities Granger cause changes in the probabilities of the Cup result implied by odds in the market on that outcome. In addition, economically and statistically significant evidence of momentum is found in the odds in the market on the Cup result.     

Technical efficiency and ICT investment in Italian manufacturing firms

The importance of Information and Communication Technologies (ICTs) is a much debated question with extensive literature aimed at understanding the role of ICTs in increasing economic growth, firm productivity and firm efficiency. Different methods to estimate firm efficiency are used in this study. In particular, both the translog and the Cobb–Douglas production functions are used in order to estimate the impact of ICT on Technical Efficiency (TE) in Italian manufacturing firms over the period 1995 to 2003. Results show that ICT investments positively and significantly affected firms’ TE. Moreover, group, size and geographical position have a positive influence on TE. Finally, the results show that older firms are, on average, more efficient than newer ones.     

Local government efficiency: determinants and spatial interdependence

We analyse the determinants of local government efficiency taking into account the presence of spatial interactions among neighbouring municipalities. To do so, first we estimate an efficiency index using the robust order-m methodology in Valencian municipalities (Spain). Second, we examine the socio-economic, political and budgetary factors that might influence efficiency levels. Finally, we analyse the spatial interactions present in our data. The results of estimating a spatial autoregressive model show that government efficiency in neighbouring municipalities positively affects the local government’s own efficiency. This highlights the importance of considering spatial dependence structures in studies on efficiency in the public sector.     

The Brazilian Soccer Championship: an efficiency analysis

This article analyses the top Brazilian football league from 2003 to 2011 by estimating a cost function and using a stochastic frontier model. Among the covariates, the number of fans per club and club remoteness is taken into account. The Brazilian clubs are then ranked according to their technical efficiency during the 2000–2011 period. Based on the results, the policy implication is presented, and the economic implications arising from the study are also considered.     

Energy efficiency in transition economies

This article outlines and estimates a measure of underlying efficiency in electricity consumption for an unbalanced panel of 27 transition economies and 6 European OECD countries between 1994 and 2007. A Bayesian Generalized True Random Effects stochastic frontier model with persistent and transient inefficiency is considered by estimating an aggregate electricity demand function that leads to consumption efficiency scores, giving further insights than a simple analysis of energy intensity. There is evidence of convergence between the CIS countries and a block of Eastern European and OECD countries, although other country groups do not follow this tendency, such as the Balkans.     

Elasticity of substitution and technical efficiency: evidence from the US electricity generation

ABSTRACT

The implications of national or regional energy policies for technical efficiency and environmental outcomes in electricity generation depend on fossil fuel input substitution. This study uses state level data to examine fossil fuel (coal and natural gas) substitution in electricity generation under increased availability of natural gas in the United States. We observe that changes in elasticities of substitution from pre-2009 to post-2009 differ across states suggesting that the effects of increased availability of inexpensive natural gas on electricity generation have been spatially heterogeneous. We rely on the observed heterogeneity to assess the effects of fossil fuel input substitution on technical efficiency and CO₂ emissions. The results reveal that state level elasticity of substitution between natural gas and coal has a positive effect on technical efficiency and a negative effect on CO₂ emissions. Therefore, future policy design and analyses should reflect the implications for regional elasticities of fossil fuel substitution and associated environmental outcomes.     

The determinants of banking efficiency in Hong Kong 2004-2014

The cost efficiency of the Hong Kong Banking sector over the period 2004–2014 is estimated by data envelopment window analysis. A second stage regression analysis finds that bank size and GDP growth are positively associated with efficiency, whereas revenue diversification and inflation are associated with lower efficiency. Stock exchange listing status is associated with lower efficiency but no clear relationship between measures of market structure and efficiency is found.     

A performance assessment of Mozambique banks: a Bayesian stochastic frontier

This article analyses the technical efficiency of Mozambican banks from 2005 to 2014 with a Bayesian stochastic frontier model. The intermediate approach is adopted and the results reveal that efficiency varies amongst the banks analysed. Foreign ownership of Mozambican banks is also analysed, as is public ownership, the role of mergers and acquisitions, big banks and active dividend policy within the context of bank costs. Policy implications are then derived.     

Estimation of the efficiency of structural funds: a parametric and nonparametric approach

This article seeks to perform an analysis of the efficiency of the application of the structural funds in the regions classified as Objective 1 over the period 2000 to 2006, applying the techniques known as Data Envelopment Analysis (DEA) and stochastic frontier. In the first place, we are going to identify which are the most efficient regions. Finally, we will analyse the extent to which certain factors have repercussions on the efficiency such as country, geographical location and contribution of agriculture of Gross Domestic Product (GDP) and the result indicates that some of these variables have significantly influences of technical efficiency.
