The aims of the paper are to evaluate the relevance of environmental factors (seasonality, size and quality) on hotels’ performance and benchmarks; to measure the bias in efficiency resulting from a failure to control for these sources of heterogeneity; and to propose some managerial policies to handle for environmental heterogeneity.

The sample is constituted by 2,705 hotels operating in Emilia-Romagna (Italy). The metafrontier approach is used to identify the different production processes and measure technical efficiency scores.

Different production processes exist among accommodation firms due to environmental features; not considering heterogeneity in technological sets produces high levels of bias in the efficiency measurement, albeit the ranking of hotels tends to be fairly consistent; the star rating is the primary source of efficiency bias followed by seasonality, while size has a minor impact.

Future research could be directed to analyse the relevance of environmental heterogeneity in other areas; study the dynamics; investigate agglomeration effects; and use other methodological tools.

The analysis proposes new managerial interventions: targeted strategies to different groups; creation of networks of enterprises, clustered mainly in respect to size for highly rated enterprises and seasonality for low-rated enterprises; and incentives to annual hotels and raise in the product quality.

This paper simultaneously considers several environmental factors affecting heterogeneity in hotel production processes; investigates the effect of heterogeneity on either the efficiency scores or the ranking of hotels; and focuses on micro, low-quality or seasonal hotels.

Does MFIs agricultural credit influence the determinants of the efficiency of SFF which are socio-economic factors of the farmers but also agricultural endowments of family farms? This paper aims to study the contribution of MFI services on improving the technical efficiency of SFFs in Cameroon.

The stochastic frontier analysis (SFA) model permits the estimation of the technical efficiency indicators for beneficiaries and nonbeneficiaries of agricultural credits on a sample of 130 cocoa farming households and four MFIs of the same area between 2008 and 2011. The censored tobit model is used to assess the determinants of technical efficiency.

The results show that the SFF beneficiaries of agricultural credit have an average technical efficiency of 0.68 inferior to that of nonbeneficiaries (0.72) as expected. They are, respectively, at 0.32 and 0.28 of their full productive capacities. The results of the censored Tobit model show that socioeconomic characteristics of the producer such as age and gender explain negatively, while experience explains positively the technical efficiency of SFFs.

Although without any selectivity bias, this study indicates the essential character of the socioeconomic factors in the amplification of the role of the MFIs credit on the efficiency of SFFs.

Strategies to improve the efficiency of SFFs require an increase in MFI credits, primarily targeting young, experienced and female farmers.

This study examines the efficiency of SFFs by highlighting the interaction between the socio-economic factors of farmers and the credit of MFIs. It also points to the problem of monitoring the implementation of agricultural financing.

The purpose of this paper is to clarify agricultural services into five categories, including agricultural materials supply service, financial service, technical service, machinery service and processing and sales service, and to examine the effect of agricultural services on cost saving of rice production in China.

Based on a three-year panel data set covering 3,421 rice farmers in 12 Chinese provinces collected from the state rice industry experiment stations’ fixed watch points of China Agriculture Research System, a stochastic frontier model which takes the price vectors of input variables into cost function is developed by stochastic frontier analysis method in the study.

There is a deviation between the actual cost and the minimum cost on rice production in China due to the loss of cost efficiency, whose score is 0.7983 at the mean. Agricultural services can help improve cost efficiency, thus contributing to cost saving. Specifically, the effect of technical service on cost saving is the highest, followed by processing and sales service, machinery service, financial service and agricultural materials supply service.

The results of this paper are of great significance to the effectiveness and efficiency of the targeted agricultural services and indicate implications for policy improvement under the context of clear upward trend of agricultural production costs.

This paper explores the issue of efficiency in European banking. It tries to distinguish among the market‐structure and efficient‐structure hypotheses by incorporating into our empirical analysis measures of X‐efficiency and scale‐efficiency. Tests of the four hypotheses (the two market power hypotheses and the two efficient structure hypotheses) were performed by regressing measures of concentration, market share, X‐efficiency and scale efficiency against profits. Our empirical findings seem to suggest that the two efficient structure variables do not help in the explanation of the variability of bank profits and, hence, these results do not provide any support for the two efficient structure hypotheses. Our findings also indicate that big banks are more X‐efficient than small banks. This result seems to suggest that there are cost advantages associated with greater bank size.

The purpose of this paper is to get deeper insight into the measurement of gender wage gap. A proper method to identify which part of gender wage differences is due to discrimination against women is provided, and the relationship between wage differences and education is studied.

The stochastic frontier approach is employed to measure wage discrimination against women by using Spanish data from the European Union Statistics on Income and Living Conditions. Mentioned technique allows the authors to split the gender wage gap of workers displaying the same characteristics into two components: the first measures inefficiency in the job search process caused by imperfect information or gender differences concerning preferences regarding working conditions, where as the second takes account of discrimination.

A significant level of discrimination is found in the Spanish labour market at all educational levels, but this problem is quantitatively more important when low-educated workers are studied, and gender discrimination is lower for highly educated women.

In this paper, workers’ potential wage is estimated, and gender discrimination is measured by the gender potential wage gap, since it is not dependent on other wage determinants such as diverse preferences, unmeasured working abilities or imperfect information.

The purpose of this paper is to evaluate and compare bank efficiency between the two Maghreb countries, Tunisia and Morocco, over the period 2005–2014.

The authors follow the stochastic frontier analysis, where the preferred cost model is determined via various hypothesis tests based on the maximum likelihood estimation. Then, the first and the second derivates of the cost function are employed to determine scale elasticities, scale inefficiencies and technological progress.

Specification tests indicate that the Fourier Flexible form provides better fit to the data set. Further, the estimated model shows that Tunisian and Moroccan banks’ efficiency is positively affected by banking service quality, but negatively influenced by both bank capitalization and GDP growth. Overall, Moroccan banks are found to be the most efficient despite the decrease of efficiency levels in both countries. Additionally, foreign banks have a higher scale inefficiency and, therefore, a lower cost efficiency. Equally, the technical progress raises banking costs in both countries, providing a decrease in efficiency scores.

The findings of this study provide novel insights to Tunisian and Moroccan policy makers on the relevance of the smaller banks’ consolidation to improve bank efficiency by achieving unrealized economies of scale. Also, more reforms should be implemented in Tunisia to reduce non-performing loans.

To the best of the authors’ knowledge, this study is the first which offers a comparison between Tunisian and Moroccan banks to clarify the sources of inefficiency and to make strategic decisions.

This paper is the first comprehensive investigation of the shipping industry's efficiency in five countries from the ASEAN region: Malaysia, Singapore, the Philippines, Thailand and Vietnam.

Employing Data Envelopment Analysis and Stochastic Frontier Analysis, this paper compares efficiency dynamics of 45 international and offshore shipping providers engaged in fishing and ferrying.

The results indicate consistently diminishing efficiency from 2011 to 2017, a phenomenon that persists even in the traditionally efficient companies. Thereafter, this paper develops Altman Z-scores for the sampled companies and notice that despite rising inefficiency, most firms remain unencumbered by bankruptcy concerns, especially those with large capital buffers.

In general, this paper observes a negative relationship between bankruptcy risk and efficiency. Furthermore, the paper notices that reducing inputs does not help boost efficiency.

In terms of novel contributions, this paper is the first (to the best of knowledge) to set a Z-score for the ASEAN-based shipping companies.

The purpose of this paper is to measure the efficiency performance of public sector-funded schools in Spain.

Using school-level data from Program for International Student Assessment 2012, cross-sectional models were estimated using stochastic frontier analysis (SFA). Technical efficiencies of public sector-funded schools (public schools and centros concertados), and their determinants were estimated using a one-step maximum likelihood procedure. SFA models include both a stochastic error term and a term that can be characterized as inefficiency; the non-negative technical inefficiency effects are assumed to be a function of school characteristics.

The results show that greater school autonomy and school responsibility for resource allocation are associated with efficiency improvement. Subsidized private schools (called centros concertados) were more efficient than public schools. The former are free of bureaucratic constraints that encumber public schools, and they are able to control many more decisions at the school level (e.g. they select their own teachers).

This paper shows the value of school autonomy for educational performance. The author defines school autonomy as the operational empowerment of the principals and teachers. Therefore, the government could grant greater autonomy to public schools (school-based management), since school autonomy is a driver of efficiency. Further, teachers’ morale is also an environmental driver of efficiency. Schools tend to be more efficient when teachers work with enthusiasm or value academic achievement. And this is more likely to occur in private schools, even though teachers are hired (they are not civil servants) and have a lower salary than public school teachers. The lack of motivation of many teachers in public schools may be in the absence of incentives – there is no possibility of promotion and everyone is guaranteed a wage increase every three years –and in the bureaucratization of the public school system.

Testing the efficiency in the economy has been highly pronounced since the financial crisis in 2008, as many countries have started to deregulate their economic sectors. The potential impact of testing efficiency is thus the key driver of world output and welfare. For this purpose, the main objective of the Capital Market Authority consists of more regulation of securities trading to boost economic efficiency. In particular, the purpose of this paper, is to examine the efficiency of 40 investment companies in Kuwait. In this study, the authors investigate the efficiency in the investment sector in Kuwait. Studying such a case is important for several reasons. First, the investment sector in Kuwait is affected by the World Trade Organization (WTO) conditions and regulations for more market liberalization. Second, most studies on efficiency have focussed on developed countries, such as those of Europe and the USA, with very few studies examining developing countries, such as Kuwait. Third, the study efficiency features is important in helping policy makers evaluate how the investment sector will be affected by increasing competition and then formulate policies that affect that sector and the economy as a whole.

In this study, we use non-parametric data envelopment analysis (DEA) to estimate investment companies’ efficiency in Kuwait. The authors test predictions of the model using yearly data for 2006-2010. In the analysis, the authors follow the two-stage approach suggested by Coelli et al. (1998). In the literature on DEA efficiency score measurement, this two-stage approach is the most prominent. This approach uses the efficiency score, measured by the DEA model, as the dependent variable in a regression model with explanatory variables that are supposed to capture the impact of external factors (Hahn, 2007). In the second stage, the authors used a Tobit model to investigate factors affecting the efficiency in the Kuwaiti investment sector.

The findings of the second stage suggest that 2008-2010 had a negative impact on firms’ efficiency in Kuwait. The results confirm the substantial influence of the 2008 global financial crisis on the investment sector in Kuwait. In addition, the results show that factors affecting production efficiency in the investment sector in Kuwait include the total revenues, total assets, government participation, and Islamic firm dummy. These second-stage results are confirmed using different specifications of a fixed effect model, a random effects model, and a logit model.

The results may be utilized by both monetary authorities and policy makers in establishing the general economic policy in the country. A number of policy implications may be derived from the estimates obtained in the current paper. First, the results show that the investment sector in Kuwait faced a sharp drop in its efficiency in 2008 due to the global financial crisis. This result tells us that there was a spillover effect of the global financial crisis in the Kuwaiti investment market, as companies in this market are highly vulnerable to global shocks. As a result, the investment sector needs to be regulated by, for example, encouraging more company mergers and acquisitions. Second, to meet the appropriate regulations in the investment sector in Kuwait, monetary authority in Kuwait should take into consideration the WTO conditions for more openness in the economic sector. Therefore, companies in the investment sector should be more efficient to compete with foreign investment companies that decide to enter into Kuwaiti market. Therefore, the need for regulations in the Kuwaiti investment sector is more necessary than before. Third, the study of efficiency features is important to help policy makers evaluate how the investment sector will be affected by increasing competition and then formulate policies that affect that sector and the economy as a whole. Furthermore, monetary policy can play an important role in influencing the efficiency in the investment sector. Therefore, the Central Bank of Kuwait should take a leading role in regulating abnormal financial activity in the Kuwaiti market.

The purpose of this paper is to assess how spatial heterogeneity and production diversification have affected the efficiency of households participating in the SLCP.

Based on household survey data collected from three sample counties in the Loess Plateau region, the paper analyzes how spatial heterogeneity and business diversification have affected the production efficiency of households participating in the SLCP. Using four-step bootstrap, input stochastic distance frontiers of multi-inputs and multi-outputs are developed simultaneously with a technical efficiency effects model in which participating in the SLCP is treated as an exogenous variable.

The household production in the three counties is constrained by land, labor, capital, and fixed inputs; thus, it is germane to using a multi-input and multi-output household production technology to evaluate the SLCP. However, the relative importance of each input and output, the productive diversification, and the technological structure are differentiated in the three counties; estimating the regression with pooled data appears to conceal the influences of local factors and blur the specific divergence, compared to running county-based, separate regressions.

The effects of the SLCP on farm household production are location dependent. It is necessary to include spatial heterogeneity within public policy evaluation. In addition to suggesting localized and differentiated schemes of subsidy, this implies that the government may provide means to facilitate different regions to make the economic transition.

This paper intends to make two contributions. First, the analysis will capture and explain the adjustments induced by the SLCP in off-farm and other activities for entire household production, and special attention is given to the diversification of household production outputs. Second, this analysis sheds new light to the significance of spatial differentiation in mediating the effectiveness of a public policy or program.
