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.

Employment Protection and Banking Power: Evidence from Adoption of Wrongful Discharge Laws

Human capital and labor costs are crucial for the sustainable growth of organizations, and take a vital role in affecting bank efficiency and banking power. This research empirically investigates whether labor employment protection affects banking power. The analysis exploits the staggered adoption of Wrongful Discharge Laws (WDLs) as a quasi-exogenous shock to employment protection. A Difference-In-Difference research design is implemented to study the impacts of WDLs on banking power, and the main results show that there exists a decline of banking power for commercial banks headquartered in states that adopt employment protection. This study further tests the main mechanism through which WDLs affect banking power and finds that the impaired banking power is primarily due to cost inefficiency but not profit inefficiency. Moreover, the adoption of wrongful discharge laws increases commercial banks’ labor costs and induces bank risk-taking.

Econometric Approaches

Econometric approaches provide another avenue to implementing the frameworks and concepts of dynamic efficiency and productivity measurement. This chapter addresses both structural and reduced-form econometric approaches to estimating the dynamic directional distance function directly as well as to estimating the cost function that accommodates technical inefficiency. An application to a farm-level panel data set is presented that estimates the decomposition of dynamic cost inefficiency into technical and allocative inefficiency measures presented in Chapter 4 and then determines the components of primal and dual Luenberger total factor productivity change based on the elaboration of these concepts in Chapter 5. In addition to the discussion of empirical issues, this chapter provides an empirical illustration using micro-level data.

Nonparametric Approaches

This chapter focuses on the nonparametric data envelopment analysis (DEA) framework of structural linear programming models underlying the estimation of efficiency. The nonparametric approach to measuring technical and cost inefficiency has been adopted in the examples in earlier chapters. Chapter 3 introduced the notions of inner- and outer-bound technologies. The inner-bound technology representation has dominated the nonparametric empirical applications in the literature on measuring efficiency and productivity. However, as this chapter shows, the outer-bound representation of the technology presents a viable alternative to measuring technical and cost efficiency as well. The chapter also develops an application to farm-level panel data.

Calculative Trust and Interfirm Contracts

Interfirm contracts are plagued by opportunism arising from exchange hazards that increase the seller’s gains from holdup in fixed price contracts. These exchange hazards are higher when the seller can engage in unverifiable deliberate obfuscation. Although cost-plus contracts reduce holdup losses, they suffer from cost inefficiency. Past research has underscored the importance of trust as a control instrument to mitigate losses from exchange hazards, especially social relational trust that develops from past experiences. However, trust can also be calculative when it develops from the expectation of future economic gains to the buyer-seller dyad. We identify two dyadic mechanisms that generate calculative trust and curtail the likelihood of cost-inefficient behavior in cost-plus contracts. These mechanisms include future potential and bilateral reputation capital for cost containment. Analysis using probit estimations on 149 information technology outsourcing contracts for the period 1998 to 2005 suggests that calculative trust increases the likelihood of cost-plus contracts. Thus, calculative trust can mitigate inefficiencies in interfirm contracts. This paper was accepted by Shiva Rajgopal, accounting.

Determinants of banks’ cost efficiency: a case study of selected commercial banks, Ethiopia

This study examines the determinants of cost efficiency commercial banks’ in Ethiopian using balanced panel data with a sample of 13 commercial banks over the period 2010-2017 by paying a translog stochastic cost frontier approach. The identification and selection of inputs and outputs variables was based on the intermediation approach. Accordingly, three input variables (cost of labor, cost of capital, and cost of fund) and two output variables (total loans and other earning assets) are used in the study. Furthermore, five banks specific and one macroeconomic variable are included to examine their effect on cost efficiency. So as to examine the effect of determinant variables which are associated with banks efficiency, a single stage maximum likelihood estimation method is applied to stochastic frontier cost function. The empirical estimations were accomplished by Appling a single stage maximum likelihood function assimilated into Stata software. The estimation is based on conditional mean model concepts. The finding shows that from bank specific factors, return on assets (ROA), and intermediation ratio have positive and significant for intermediation (IR) and insignificant for ROA with cost inefficiency. On the other hand, Bank size (lnTA), Credit risk (CR) and capital adequacy ratio (CAR) have a significant negative coefficient with cost inefficiency. GDP also has negative but insignificant with inefficiency. Therefore, banks are recommended to improve and sustain their efficiency by maintaining available proportion of capital adequacy ratio and attract high value, low interest-bearing demand deposits.
