The nexus between competition and efficiency: The European banking industries experience

In this paper, we investigate competition in banking systems in the EU27 as a whole for the period 2004–2010, but also for old members’ banking systems compared with new members’ banking systems and for banking systems from countries member of euro zone compares with banking systems from countries non-member of euro zone. In order to investigate this issue, we estimate a non-structural indicator of banking competition, using the H-statistic indicator that is estimated using bank-level data. Also, we apply two tests of convergence, β- and σ-convergence, for assessing competition evolution during the specified period. We want to fill the gap in the banking literature testing the validity of the Competition–Efficiency Hypothesis, analysing the impact of the banking competition measures on two alternative measures of efficiency, cost and profit efficiency, in the European banking systems in a Granger-causality manner. The results confirm us that in the EU the convergence process occur from the banking systems with higher competition level than the mean score of all countries. The evidence for all groups of countries, except non-euro zone group, where results are not statistically significant, confirm the Competition–Efficiency Hypothesis in terms of cost and profit efficiency.     

Port geography at the crossroads with human geography: between flows and spaces

Port research is not a new field of interest for human geographers, evidenced by numerous conceptual models and empirical cases of port evolution and development in the literature. However, several critical questions remain unanswered, notably the exact position of port geography as a subdiscipline within human geography in the past, present and future. Based on a pluralistic approach, the paper analyzes the changing waves and development of port geography as a sub-discipline of human geography, with a special focus on whether port geography has experienced a paradigm shift and, if so, when, why, and how. Also, through analyzing the major terrains of port geography research from the macro perspective, it brings a new lease of life to port geography in this rapidly changing world.

Bribery,corruption and bureaucratic hassle: Evidence from Myanmar

Corruption has been found to be the most severe obstacle to business operations, according to a recent survey of over 3000 firms in Myanmar. This paper sets out to understand the structure of corruption through an econometric analysis of this survey. It finds that firms with higher ‘ability to pay’ (proxied by sales revenue and employee growth) are more likely to pay bribes. While firms with lower ‘refusal power’ (i.e. those dependent on bureaucratic permissions to export and import) are more likely to find corruption to be an obstacle. A distinct but related question is whether bribes act as ‘efficiency grease’ by allowing firms to circumvent red tape. No evidence is found to support this hypothesis; in fact, firms that pay bribes report greater bureaucratic hassle compared to firms that do not. This result fits in more closely with the view that red tape could be used to extract bribes from firms.     

Comparing efficiency of holding business model and individual management model of airports

This research compares the efficiency of holding business model to individual management model of airports, employing some robust non-parametric partial frontier-based methods to compare the statistical distributions of efficiency, under different scenarios, to find out which group of airports yields better global performance. The comparison between groups will follow a Malmquist index decomposition, which seems to be the most appropriate tool for within- and inter-group performance comparison. For this purpose, a sample of 145 airports from three continents is utilized. The results provide evidence that European airports are the most productive ones, and within this cluster, the individual management model presented a significant frontier shift with respect the holding cluster frontier, meaning that the former is much more productive than the latter.     

Dynamic DEA models with network structure: An application for Iranian airlines

Efficiency estimation of interdependent divisions within a company or assessing the interrelated processes in a production system provides insights for improving the operational performance. Recent developments in network data envelopment analysis (NDEA) models enable decision making units (DMUs) to be informed of inefficient processes within the system. The NDEA model assesses the processes of the system in a specific moment and ignores the dynamic effects within the production processes. Thus, without considering the temporal dimension of production processes, biased efficiency measurement will be obtained that provides misleading information to DMUs. For evaluating the performance of a DMU with interrelated processes during specified multiple periods, this paper proposes a relational dynamic NDEA (DNDEA) model which measures the efficiencies of the system and its internal processes over the time, simultaneously. To illustrate the capability of the proposed model, this study for the first time measures the efficiency of eight Iranian airlines in several periods connected to each other by carry over flows. The actual data is gathered in three periods from 2010 to 2012 and the results are compared with the dynamic DEA and network DEA models in the same time span.

On discrimination in the optimal management of teams

We study the optimal management of teams in which agents’ effort decisions are mapped (via a production technology) into the probability of the team’s success. Optimal wage schemes in such context are largely discriminatory, but we show that the extent of the discrimination crucially depends on the existence of moral hazard. More precisely, for teams with a flat structure, the domain of production technologies giving rise to discrimination is broader when agents’ actions are observable and contractible. For teams with a sequential structure, the result reverses and the domain of production technologies giving rise to discrimination is broader when there exists moral hazard. Finally, in more cooperative environments in which agents are allowed to collude, optimality does not entail discrimination, with or without moral hazard.     

Evaluating the multi-period efficiency of East Asia airport companies

The aim of this study is to analyze how internal operating sub-processes and annual operations of airport companies influence the overall efficiency. The multi-period Network Data Envelopment Analysis is used to evaluate the efficiencies and the efficiency changes for East Asia airport companies. The results indicate that the overall efficiencies of airport companies during a specified period of time are affected by the system efficiency and the sub-processes’ efficiencies in individual periods. Furthermore, the overall efficiency change is determined by the sub-processes’ efficiency changes. According to the operating decision analysis matrix, managers can discover the inefficient sub-processes and formulate the improvement countermeasures.
