Freeware as a competitive deterrent

Using perfect foresight and adaptive models, this paper examines the effect of competitor asymmetry, consumer sensitivity to incentives and adaptive processes on freeware strategies and competitive outcomes. Four roles played by freeware in competitive markets are identified – it can be a mechanism to build or speed up the growth of a network without the need to lower prices on the commercial version, a deterrence mechanism, a hindrance to a rival’s network building efforts, and a coordination device in the presence of forward looking consumers. We determine the optimal prices of the commercial version, the decisions to introduce freeware and the freeware qualities for both competing firms.     

Integrating the critical success factor method into the business process outsourcing decision

This paper outlines a framework that integrates the critical success factor (CSF) method into the outsourcing decision. The framework builds upon the generic outsourcing evaluation methodology and uses the CSF method as a means of evaluating outsourcing at the business process level. The findings from applying the outsourcing framework in a retail bank are presented. The research found the application of the framework delivered positive results in business process outsourcing decisions. As well as linking outsourcing with organisational strategy, it provided a mechanism and language for prioritising which processes require attention through either internal improvement or outsourcing. However, the findings identified a number of challenges with applying the framework including defining processes and understanding complex interdependencies between business processes prior to outsourcing.

Allocative and scale efficiency among maize farmers in Zambia: a zero efficiency stochastic frontier approach

The commonly used stochastic frontier model assumes that all firms are inefficient. In this specification, inefficiency is non-negative, and the probability of inefficiency being exactly zero is also zero. To the extent that efficiency varies widely across farms in under-developed economies, it is important to employ techniques that account for both inefficiency and full efficiency to ensure unbiased efficiency estimates. In this study, we employ a zero-inefficiency stochastic frontier model to examine allocative efficiency and scale economies, as well as key determinants of efficiency among Zambian maize farmers. The results show that, unlike the stochastic frontier model, the zero-inefficiency stochastic frontier model successfully allows for both fully efficient and inefficient firms to be accounted for in the estimation procedure. The estimates also reveal the presence of scale economies, with the zero-inefficiency stochastic frontier model better predicting scale efficiency compared to the stochastic frontier model. The findings also show that inefficiency is explained by the level of education, access to extension services, distance to markets and access to credit.     

Modelling superannuation fund management function as a two-stage process for overall and stage-level performance appraisal

We assess superannuation fund performance in a multi-dimensional framework by conceptualizing its management function as a serially linked two sub-process; operational management (OM) and portfolio management (PM). The procedure that we adopt is data envelopment analysis (DEA). We express overall efficiency as a weighted average of the two sub-process efficiencies and assess overall efficiency conditional on their relative importance. We demonstrate application of our model using a sample of Australian superannuation funds. By appraising performance in two sample periods; crisis (2008) and relatively non-crisis (2014), we show that some findings of previous studies may be explained further through the proposed multi-stage framework. The best overall performer in 2008 is public sector funds and in 2014 it is corporate funds. Decomposition of overall efficiency reveals that public sector funds, on average, outperform all other fund categories in OM. However, no specific fund category dominates PM performance in both assessment periods. The driving force behind the observed inverse association between superannuation fund size and performance appears to be PM performance. Number of investment options offered is not associated with overall, OM and PM performance. Here, we demonstrate that performance appraisal from different aspects of management provide insightful information to superannuation fund managers.

Cost and learning efficiency drivers in Australian schools: a two-stage network DEA approach

This article explore performance issues in Australian public schools, using a two-stage DEA network model, which accounts simultaneously for both cost and learning efficiency levels. In the cost efficiency stage, different types of expenses and investments are employed to support a given number of students, teachers and administrative staff. In the learning efficiency stage, these groups of individuals help to produce important outputs related to performance in student tests and school rankings. Results indicate that Australian public schools are heterogeneous. Policy implications are also discussed.     

On the efficiency of environmental instruments in a spatial economy

This paper develops an efficiency criterion to evaluate environmental policy instruments in a spatial economy. We call an environmental policy regime at the regional level efficient if it guarantees not only an efficient distribution of emission permits within a region, but also an efficient locational pattern of mobile firms across the regions of a federation. Using marketable pollution rights or emission taxes, efficiency in this broad sense can only be achieved if revenues of regional environmental agencies are not transferred to regional firms. Direct controls neither support an efficient allocation of emission rights within a region nor locational efficiency of firms.     

An analysis of innovation in textile companies: An efficiency approach

The elimination of trade contingency measures in 2005 triggered a process of renewal in the textile sector, requiring major investments. The divide between efficiency and innovation has become an issue of major importance for decision-making in the Spanish textile sector. This study provides quantitative data on the efficiency levels of innovative Spanish textile companies. The aim is to identify their distinguishing features and establish a possible pattern to follow. In addition, truncated regression is used to estimate the determinants of efficiency, in order to check the significance of innovation processes for firms.     

The evolution of stock market efficiency in the US: a non-Bayesian time-varying model approach

A non-Bayesian time-varying model is developed by introducing the concept of the degree of market efficiency that varies over time. This model may be seen as a reflection of the idea that continuous technological progress alters the trading environment over time. With new methodologies and a new measure of the degree of market efficiency, we examine whether the US stock market evolves over time. In particular, a time-varying autoregressive (TV-AR) model is employed. Our main findings are: (i) the US stock market has evolved over time and the degree of market efficiency has cyclical fluctuations with a considerably long periodicity, from 30 to 40 years; and (ii) the US stock market has been efficient with the exception of four times in our sample period: during the long recession of 1873–1879; the recession of 1902–1904; the New Deal era; and the recession of 1957–1958 and soon after it. It is then shown that our results are partly consistent with the view of behavioural finance.     

Contract farmer and poultry farm efficiency in Bangladesh: a data envelopment analysis

The objective of this article is to determine the efficiency of the poultry farm in Bangladesh and to assess the influence of contract farming system, using a data envelopment analysis. Seventy-five commercial poultry farms (25 and 50 independent and contract farms, respectively) were randomly selected. The results reveal that efficiency scores vary across sample farms. To explain some of these variations, the efficiency scores were regressed on some human capital variables and farming system using a Tobit model. The study also estimates elasticities to provide the information on the magnitude of the influence of variables on Technical Efficiency (TE), Allocative Efficiency (AE) and Economic Efficiency (EE). The results show that the contracting system is positively and significantly related to the farm's TE, AE and EE. This is expected because under contractual agreement, in order to obtain sufficient supplies of the right quality of poultry meat at the right time, the company provides technical know how assistance through company's recruited supervisor, production inputs and services, and production credit along with intensive supervision, which in turn improves farm efficiency. Thus, by receiving technical know how contract farmers have gained more knowledge on their resource and practices, which enables them to use resources more efficiently. Empirical results can provide crucial information to policy makers that improve poultry farm efficiency.     

Competition and efficiency in the MENA banking region: a non-structural DEA approach

The goal of this article is to empirically assess the relationship between competition and efficiency in the banking sector of Middle East and North African (MENA) countries spanning the period 1997–2011. To measure the level of competition, the article estimates the non-structural indicator known as the H-statistic, while the level of bank efficiency is estimated through the nonparametric methodology of the Data Envelopment Analysis (DEA) and the Bootstrap Data Envelopment Analysis (BDEA), respectively. The empirical results are robust under six econometric methodologies, providing sufficient evidence for the presence of a one-way (negative) Granger causality, running from efficiency to competition. The empirical findings lead to the rejection of the ‘Efficient Structure Hypothesis’, implying that increases in competition do not precede increases in cost efficiency.

The efficiency of social public expenditure in European countries: a two-stage analysis

Do European countries differ in the efficiency of their welfare policies? And which factors can account for such variability? To address these questions, we perform a two-stage efficiency analysis. First, based on a composite output indicator for social protection expenditure, we measure efficiency by means of the Free Disposable Hull and Data Envelopment Analysis techniques. Second, we perform an econometric analysis to identify the factors that can be associated to cross-country differences. We find that countries scoring higher efficiency have higher education and GDP levels, a smaller population size, a lower degree of selectivity of their welfare systems and a lower corruption level.     

A comparative analysis of the change in R&D efficiency: a case of R&D leaders in the technology industry

This paper measures the cumulative change in research and development (R&D) efficiency of globally leading R&D companies in the technology industry. We use Data Envelopment Analysis /Malmquist index to analyse 49 such companies. The change in R&D efficiency is analysed by decomposing the Malmquist index into ‘catch-up’ and ‘frontier shift’ indices, and by comparing cumulative indices to those at the starting period. Those cumulative indices are obtained at both a firm and an industry level. Results indicate that the overall R&D efficiency of these globally leading R&D companies declined slightly during the period 2007–2013. At a firm level, this study determines in detail how the trend of each firm in R&D activities differs from other companies.     

Changes in household composition as a shock-mitigating strategy

This paper uses data from the Russian Longitudinal Survey that span the two recent economic recessions of 1998 and 2008 to study the effect of declining incomes on household composition. We hypothesize that individuals face a trade-off between taking advantage of economies of scale and specialization when living with others, and individual privacy. Consumption smoothing is achieved by forgoing privacy during the crisis and results in increases in household size. Our empirical results suggest that members of households that experienced negative income shocks are more likely to move in with others compared to individuals residing in households whose income remained the same or increased.     

Public and private inputs in aggregate production and growth: a cross-country efficiency approach

In a cross section of OECD countries, we replace the macroeconomic production function by a production possibility frontier, total factor productivity being the composite effect of efficiency scores and possibility frontier changes. We consider, for the periods 1970, 1980, 1990 and 2000 one output – GDP per worker – and three inputs – human capital, public physical capital per worker and private physical capital per worker. We use a semi-parametric analysis, computing Malmquist productivity indexes, and we also resort to stochastic frontier analysis. Results show that private capital is important for growth, although public and human capital also contribute positively. A governance indicator, a nondiscretionary input, explains inefficiency. Better governance helps countries to achieve a better performance. Nonparametric and parametric results coincide rather closely on the movements of the countries vis-à-vis the possibility frontier and on their relative distances to the frontier.     

International stock market efficiency: a non-Bayesian time-varying model approach

This article develops a non-Bayesian methodology to analyse the time-varying structure of international linkages and market efficiency in G7 countries. We consider a non-Bayesian time-varying vector autoregressive (TV-VAR) model, and apply it to estimate the joint degree of market efficiency in the sense of Fama (1970, 1991). Our empirical results provide a new perspective that the international linkages and market efficiency change over time and that their behaviours correspond well to historical events of the international financial system.
