Transient and Persistent Cost Efficiency in Hotels in the Canary Islands

The aim of this study is to determine the presence or otherwise of transient and/or persistent cost inefficiency in the lodging industry. To do so, we applied the method proposed by Filippini and Greene, within a stochastic frontier panel data framework. Our empirical analysis is based on data for the hotel industry in the Canary Islands (Spain), an important destination for European tourists, for the period 2002-2015. Using a stochastic translog cost frontier model, we show that the industry’s real output during the study period could have been achieved at 17% less cost if persistent (systematic) inefficiency were eliminated, and at 24% less cost in the absence of transient (nonsystematic) inefficiency. We also present evidence of factors that strongly influence hotels’ transient cost efficiency, such as the positive effects of market share (in total revenue terms) and certain management characteristics, including the degree of independence with respect to shareholders, the experience in the industry (years in business) and the number of subsidiaries.

Estimating the Market Power of Traders in the Arabica Coffee Value Chain in Lam Dong, Vietnam

Although some studies have assessed the market power of advanced degrees in Vietnam’s agricultural sector, this research only focuses on analyzing the level of market concentration through CR4 or HHI indexes. The stochastic cost frontier can estimate market power using the Lerner ratio when input price data are not available and with or without constant returns to scale. Thus, the stochastic cost frontier with a maximum likelihood approach of Kumbhakar et al. (2012) is used to assess the market power of traders in the coffee value chain in Lam Dong province, Vietnam. The estimated market power and Lerner rate results are 0.0001. This index shows that the local coffee market is a market with perfect competition. So the traders do not have market power. Thus, there is no collusion between coffee traders to lower the purchase price for farmers or increase the price for processors and exporters. An RTS ratio of 0.96 (less than one) shows that the return to scale for traders is decreasing. This number proves that the degree of competition in the local coffee market among traders is very high.

Does regulation induce cost efficiency in electricity distribution utilities? Use of stochastic cost frontier analysis for the Indian states

To overcome the macroeconomic crisis of the early 1990s, the Government of India persuaded the state governments to adopt market-oriented reforms for loss-making state public sector undertakings in general and power sector utilities in particular with an aim to limit the overall size of the public sector. This led the state governments to undertake unbundling of their vertically integrated State Electricity Boards (SEBs), establish independent regulatory bodies in the form of State Electricity Regulatory Commissions (SERCs) to regulate the power sector, and allow for an active participation of private sector. Given this backdrop, the present study attempts to examine the effect of establishment of SERCs on the cost-efficiency of electricity distribution in the Indian states. Thereby, it evaluates whether the establishment of SERCs has induced efficiency gains in the electricity distribution. Estimating a Cobb-Douglas stochastic cost frontier function, it finds that the establishment of independent regulators in various states has resulted in significant improvements in the cost-efficiency in the electricity distribution.

Estimating Islamic Banks’ Technical and Allocative Inefficiencies: A Shadow Cost Approach

The main objective of the present paper is to empirically analyze the efficiency of 26 selected Islamic banks from different countries, namely: Bahrain, Jordan, Kuwait, Malaysia, Pakistan, Qatar, Saudi Arabia and UAE. The data used covers the period of 2012‒2016. To measure the banks’ efficiency, we used the frontier-based efficiency methodology, which was especially developed in the presence of panel data. In this respect, the panel data provided us with a fruitful framework for analyzing the efficiency. Therefore, the method employed was the shadow cost frontier based on the estimation of parametric cost inefficiency and its decomposition into both technical and allocative inefficiencies. The findings showed that the Islamic banks are costinefficient. With regard to the allocative inefficiency, it can be explained by excessive use of capital relative to labor, accompanied by an overuse of financial resources in terms of labor. The present study also revealed that the financial factor is overused, relative to the physical capital. Furthermore, technical inefficiency appears to be the second source of cost inefficiency as far as the Islamic banks are concerned. Overall, the findings indicate that the Islamic banks must improve their use of resources by about 43.7 percent for achieving efficiency.

Innovations and firm-level efficiency: a comparative analysis between China and India

PurposeThis study examines the innovation-efficiency linkage for Indian and Chinese manufacturing and service firms.Design/methodology/approachWe applied the stochastic production and cost frontier approach to determine the output and cost efficiency of the firms surveyed in World Bank enterprise surveys. We then used both unconditional and conditional propensity score matching (PSM) estimation techniques to examine the effects of innovation as well as R&D on output and cost efficiency of the firms surveyed.FindingsThe study results suggest that innovation-efficiency linkage varies between countries and sectors. Innovations significantly raise output and cost efficiency of Indian manufacturing firms, whereas innovations in Chinese manufacturing firms are cost-oriented and negatively affect output efficiency. For the service firms of both countries, innovations are significantly positively linked with output and cost efficiency. The study also suggests that R&D acts as a crucial moderator for innovation-efficiency linkage for Chinese manufacturing firms but not for Indian firms, and the interaction effects of innovations are not substantially higher in magnitude than their individual effects. Finally, conditional PSM results suggest knowledge spillover for effective innovations of Indian firms, whereas R&D is a must for substantial innovation-efficiency linkage in Chinese firms.Originality/valueThis study offers quite a few crucial policy decisions concerning the relationship between innovation and efficiency as well as the moderation effect of R&D on innovation-efficiency linkage. It concludes that the effects of innovation on firms' efficiency and the role of R&D as a moderator of the innovation-efficiency relationship differ between India and China across the manufacturing and service sectors.
