Productivity and efficiency change and shareholder value: evidence from the Spanish banking sector

Productivity change and shareholder value have been analysed in the banking sector in the last few years, although it should be noted that these two important aspects have been studied separately. In this regard, the main contribution of our study is to link these two lines of research by verifying whether those banks characterized by higher levels of efficiency and productivity change have a higher shareholder value. To measure changes in efficiency and productivity we use the Malmquist nonparametric technique, which is calculated from Data Envelopment Analysis (DEA) linear programming approach. The Malmquist total factor productivity index enables separation of the ‘catching up’ effect, i.e. changes over time in technical efficiency, from ‘technological change’, i.e. the shift of best practice frontier over time due to technological progress. Our results for a sample of listed Spanish banks in the period 2000 to 2004 confirm that those banks with higher efficiency and productivity changes have a higher shareholder value, even after controlling for the impact of traditional measures of performance, such as return on assets.     

The Malmquist Productivity Index and Plant Capacity Utilization

A new decomposition of the Malmquist productivity index is proposed to account for changes in plant capacity utilization. Using a primal, non-parametric specification of technology, the Malmquist index is decomposed into technical efficiency change, variations in plant capacity utilization and frontier shifts. It provides an alternative to the available methods of incorporating capacity utilization changes into measures of productivity change. Such measures are based on parametric (and, in many cases, dual) technology specifications; moreover, they typically do not allow for technical inefficiency.

Long-run technical change and multifactor productivity growth in US manufacturing

This study utilizes a translog cost function to produce econometric estimates of the separate influences of technical change versus scale efficiency in contributing to multifactor productivity growth within the US manufacturing sector. The analysis generates (two-digit) industry-specific parameters that capture the effects of output versus time-related shifts in the cost function over the 1949–1991 period. Thus initial evidence concerning the relative importance of technical progress (versus ‘scale’) cannot be provided as a source of productivity gains within two-digit industries. The parametric estimates of total factor productivity growth are compared with existing Divisia measures to explore the shortcomings of the growth accounting technique. These long-run patterns hold implications for the productivity convergence hypothesis traced to knowledge spillovers between industries.     

Information Technology and Productivity Changes in the Banking Industry

This paper analyses the effects of investment in information technologies (IT) in the financial sector using micro-data from a panel of 600 Italian banks over the period 1989–2000. Stochastic cost and profit functions are estimated allowing for individual banks' displacements from the best practice frontier and for non-neutral technological change. The results show that both cost and profit frontier shifts are strongly correlated with IT capital accumulation. Banks adopting IT capital-intensive techniques are also more efficient. On the whole, over the past decade IT capital-deepening contribution to total factor productivity growth of the Italian banking industry can be estimated in a range between 1.3 and 1.8 per cent per year.     

Efficiency in the factoring industry

The efficiency and productivity in the Italian factoring industry between 1993 and 1997 is investigated using DEA. The factoring industry is an important part of many financial systems and it has established itself as a major source of finance and credit management for a growing number of companies. However, as far as the authors are aware no studies have applied frontier methodologies to examine the efficiency and productivity of this industry. This paper focuses on the Italian market, the second largest in the world after the UK. The results suggest that there are substantial cost savings to be had in the Italian factoring industry: the mean cost inefficiency in the Italian factoring industry over the period 1993–1997 ranged between 14% and 22%. These inefficiencies are mainly generated by allocative rather than technical inefficiencies. Scale and technical inefficiencies seem to be similar in magnitude and the supposed importance of the latter typically found in the banking efficiency literature, are not observed in Italian factoring. Firm size does not appear to be related to technical, allocative and economic efficiency and the hypothesis that ownership structure influences factoring firm efficiency could not be rejected. In order to analyse efficiency change over time the Malmquist index is used. Total factor productivity was decomposed into technical change and efficiency change and the latter was further divided into pure efficiency and scale efficiency change. Productivity changes were slight over the period 1993–1996, while a substantial increase in productivity occurred between 1996 and 1997: the latter appears to be the result of a large improvement in the technology and a positive scale efficiency change, however, this was slowed down by a negative pure efficiency change.     

The impacts of membership in multi-hospital systems on cost,productivity growth and technical change

We examine whether affiliation in a multi-hospital system contributes to higher rates of total factor productivity (TFP) growth, technological progress and cost efficiency. With a 1996 to 1999 panel of 248 US hospitals (some are private nonprofit (church-related and other nonprofit) and the remaining are public (government, nonfederal)), empirical results indicate that urban system member hospitals experienced higher rates of both TFP growth and technical progress than the rates of TFP growth and technical progress experienced by urban nonsystem hospitals. Rural system member hospitals experienced smaller rates of both TFP decline and technical regress than the rates of TFP decline and technical regress experienced by rural nonsystem hospitals.     

Technological change,efficiency gains and capital accumulation in labour productivity growth and convergence: an application to the Spanish regions

The main objective of this article is to analyse labour productivity growth and convergence in the Spanish regions between 1965 and 1995, decomposing total factor productivity gains into technological progress and efficiency change by means of Malmquist productivity indices. On the basis of this decomposition, labour productivity growth is broken down into components attributable to technological change (shifts in the frontier), efficiency gains (movements toward the frontier) and capital accumulation (movements along the frontier). The approach followed in this study is based on work initiated by Färe et al., where a link between the economic growth and convergence literature and the production frontier approach was established. Furthermore, in the spirit of Quah's approach, the evolution of the whole distribution is considered. Thus, the analysis of the dynamics of the entire distribution of labour productivity and the factors behind it – technological progress, efficiency gains and capital accumulation – combine both approaches, yielding new insights into the process of productivity growth and convergence experienced by the Spanish regions over the last 30 years.     

HUMAN CAPITAL AND CONVERGENCE: A PRODUCTION‐FRONTIER APPROACH*

Using nonparametric, production‐frontier methods, we decompose labor productivity growth into components attributable to technological change (shifts in the world production frontier), technological catch‐up (movements toward or away from the frontier), and physical and human capital accumulation (movements along the frontier). We find that (1) technological change is decidedly nonneutral, (2) productivity growth is driven primarily by physical and human capital accumulation, (3) the increased international dispersion of productivity is explained primarily by physical capital accumulation, and (4) international polarization (the shift from a unimodal to a bimodal distribution) is brought about primarily by efficiency changes (technological catch‐up).     

From transition to competitionDynamic efficiency analysis of Polish electricity distribution companies1

In this paper, we test the hypothesis that the economic transition toward a market economy increases the efficiency of firms. We study 32 Polish electricity distribution companies between 1997 and 2002, by applying common benchmarking methods to the panel: the non‐parametric data envelopment analysis (DEA), the free disposal hull (FDH), and, as a parametric approach, the stochastic frontier analysis (SFA). We then measure and decompose productivity change with Malmquist indices. We find that the technical efficiency of the companies has indeed increased during the transition, while allocative efficiency has deteriorated. We also find significantly increasing returns to scale, suggesting that the regulatory authority should allow companies to merge into larger units.     

Technology elasticity and potential on energy saving and emission reduction: evidence from China

This article investigates the elasticity of different technology choices to energy efficiency and chemical oxygen demand/ammonia nitrogen emission reducing efficiency among 38 industries in China from 2008 to 2011. With data envelopment analysis, total-factor productivity growth, the common measure of technical progress, is divided into different parts: technical efficiency relative to the frontier, technology change and scale efficiency, which are regarded as three different choices of technological progress. For various industries, technology elasticity is quite different and the importance of different technical choices is diverse in the improvement of efficiency on energy saving and emission reduction. Policymakers could focus on the elasticity of different technical progress choices in various industries to improve energy and emission reduction efficiency.     

X-Efficiency and Productivity Change in Australian Banking

This paper investigates X -efficiency and productivity change in Australian banking between 1995 and 1999 using Data Envelopment Analysis (DEA) and Malmquist productivity indexes. It differs from earlier studies by examining efficiency by bank type, and finds that regional banks are less efficient than other bank types. The study concludes that diseconomies of scale set in very early and hence are not a sufficient basis on which to allow mergers between large banks to proceed. Total factor productivity in the banking sector was found to have increased by an average annual 7.6 per cent between 1995 and 1999. All of the productivity increase was due to technological advance shifting out the frontier. The banking sector's performance was less efficient relative to the frontier in 1999 than it had been in 1995.     

The productivity debate of East Asia revisited: a stochastic frontier approach

This paper applies a stochastic frontier production model to the data from Penn World Table's 49 countries over the period 1965 to 1990, to decompose total factor productivity growth into technical change and technical efficiency change. Empirical results show East Asian countries led the world in productivity growth, mainly because their technical efficiency gain was so much faster than that of other countries. East Asian countries also registered rapid technical change, which was comparable to that of the G6 countries after the late 1980s. The results provide evidence that negate the hypothesis that East Asian growth was mostly input-driven and unsustainable.     

Decomposition of total factor productivity in world health production: a stochastic frontier approach

While countries around the globe have increased spending on health care, economists and policy makers have raised concerns over the productivity and efficiency of health care. This article applies a stochastic frontier approach to address this issue using data from 141 countries for the period 1993 to 1997. From the perspective of productivity change, our results suggest that gains in population health will be greater provided that more resources are allocated to investment in human capital. We also show that the scale component accounts for 65–70% of the productivity change. That is, omitting the scale component in our case will result in a significant underestimation of the decline in the productivity of world health production. We do not find evidence supporting the hypothesis that production frontiers differ between Organization for Economic Cooperation and Development (OECD) and non-OECD countries. However, the change in productivity and scale elasticity do vary significantly between these countries.     

中国地区工业生产绩效:结构差异、制度冲击及动态表现

本文利用省级面板数据研究转型过程中中国地区工业生产绩效的动态表现。基于Kumbhakar(2000)的方法,我们将TFP增长分解为四个因素的变化。结果发现:(1)自1988年以来各地区工业部门的TFP增长率都出现了增长的趋势,其首要推动力在于技术进步率的不断提高;(2)与此同时,技术效率和要素配置效率出现了恶化,而规模效率则从恶化走向了改善。(3)上世纪90年代末的国企改革对各地区的工业生产绩效的构成造成了普遍的冲击,而民营化程度较高的东部地区受到的冲击最小。(4)通过分析绩效差异的源泉,我们进一步确认90年代末国企改革的制度性冲击促成了工业规模效率的提高,却导致了要素配置效率的短期下降,而劳动力教育水平和非国有经济比重的提高,则有助于促进工业技术进步、改善配置效率。伴随着制度变革的经济整体转型正从多个向度重构着中国地区工业化的版图。     

Cost metafrontier approach for measuring the Malmquist productivity index: An example of bank groups formed after the financial reform in Taiwan

This study attempts to provide a framework under the variable returns to scale hypothesis to account for the effect of the cost scale efficiency change in the decomposition of the cost metafrontier Malmquist productivity index (CMMPI). In addition, the meta‐cost efficiency and cost frontier gap between subordinate banks of financial holding companies (FHC) and independent banks are also examined. A total of 34 banks in Taiwan are empirically analysed from 1999 to 2012. The results indicate that the meta‐cost efficiency, meta‐technical efficiency and meta‐allocative efficiency scores of subordinate banks of FHC are better than those of independent banks. The banking industry in Taiwan is found to have an improvement in cost metafrontier Malmquist productivity. The subordinate banks of FHC are also found to exhibit positive CMMPI and decomposition components, but do not achieve a significant improvement except in the case of the technical gap ratio change. The empirical results recommend that Taiwanese banks place more policy focus on the issue of scale adjustment, which should be beneficial. Based on the CMMPI decomposed results, we can gain further understanding of the growth path to enhance operational performance.     

Economic Reform and Total Factor Productivity Growth in Indian Manufacturing Industries

A stochastic frontier production function model is applied to Indian manufacturing industries, to decompose the sources of total factor productivity growth into technical progress, technical efficiency, scale efficiency, and allocative efficiency. Empirical results based on data from 2000 to 2006 suggest that increased investment needs time to deliver increased productivity and efficiency, because new technology combined with fresh investment requires higher numbers of skilled workers, better managerial practices and an advanced input mix, all of which generally take time to develop. Thus, the Indian economy must boost technical efficiency by providing skilled workers and high quality managers to further economic reform.     

Human capital in OECD countries: Technical change,efficiency and productivity

The aim of this paper is to analyse the role of human capital in the productivity gains of the OECD countries in the period 1965-90, breaking down the productivity gains into technical change and gains in efficiency. For this purpose we use both a stochastic frontier approach and a non-parametric approach (DEA) and calculate Malmquist indices of productivity. The results obtained indicate the existence of both a level effect (a higher level of human capital raises labour productivity) and a rate effect (a higher level of human capital affects positively the rate of technical change) associated with human capital. The differences among countries in endowments of human capital have worked against labour productivity convergence, since the richer countries, thanks to their greater endowment of human capital, have experienced higher rates of technical change.     

Entrepreneurship culture,total factor productivity growth and technical progress: Patterns of convergence towards the technological frontier

A firm's set of knowledge processes may be affected by the entrepreneurial culture of the country in which it is located. Total factor productivity, mainly associated with technical progress, accounts for most differences over time and across countries. In the present work we examine the determinants of total factor productivity growth in 26 OECD countries between 1965 and 2010, breaking them down into changes in technical efficiency and shifts in technology over time. Using the US as the technology frontier, different patterns of productivity growth emerge between world technology leaders and countries with low initial levels of productivity. Whereas changes in efficiency seem to be the main result of the evolution in the stock of knowledge in technologically dependent economies, suggesting that less advanced economies can benefit from their relative backwardness, domestic research effort appears to be a relevant factor for technology leaders.     

Are Asian technology gaps due to human capital quality differences?

This paper adopts the meta-frontier framework using DEAP software to analyse the technological gap and level of catch-up of the three regions in Asia (namely, Southern Asia, Eastern Asia and ASEAN5) with respect to the Asian technology as a whole for the period 1980–2006. Countries in Eastern Asia displayed a technology gap ratio of 1.000 which posits that this region defines the best practice frontier for Asia. Meanwhile, countries in Southern Asia region displayed an improvement in technical efficiency and productivity relative to the Asian frontier but lagged in terms of technological advancement. All three regions recorded a lag in technological advancement with respect to the best practice frontier. In order to progress technologically, these countries should be equipped with the necessary infrastructure and human capital to encourage foreign investment and growth. The countries in Eastern Asia and ASEAN5 recorded the strongest productivity growth performance as a group when compared to the countries in Southern Asia. In Southern Asia and ASEAN5 region, the technology gap ratio is below 1.000 subsequent to the 1997/98 financial crisis. On the contrary, East Asia kept up with the benchmark frontier during most of the sample period inclusive of the period after the financial crisis.     

Productivity Trends in Australian and New Zealand Manufacturing

The purpose of this article is to study relative trends in total factor productivity (TFP) between the Australian and New Zealand manufacturing sectors from 1986 to 1996. Since 1984 both economies have undergone major structural changes with varying degrees of speed and intensity. We use the Malmquist index to measure TFP growth and decompose it into an efficiency change and a technical change component. This decomposition provides extra insight on assessing relative productivity trends during a period of economic reform. The results indicate the Australian manufacturing sector exhibits better rates of individual factor productivity performance while multifactor productivity is estimated to be higher in New Zealand manufacturing. TFP growth in New Zealand is driven by technical rather than efficiency change. In fact, the New Zealand manufacturing average rate of efficiency change is estimated to be negative over the sample period.
