Ground handling services at European hub airports: Development of a performance measurement system for benchmarking

The liberalization of ground handling in Europe forces airports to assess their performance relative to their competitors in order to remain competitive and sustain long-term competitive advantage. Together with main EU hub airports, action research was conducted for one year to develop a holistic performance measurement system (PMS) for ramp services. The resulting PMS entails a process-based perspective and reflects the supply chain of airport logistics. As the findings of an ex-post validation suggest, the system represents a suitable basis for competitive benchmarking activities.     

Airport capacity and inefficiency in slot allocation

This paper studies the time slot allocation of flight departures when travelers have a preference for departing on peak times and the number of available peak-time slots is constrained by airport capacities. We show that, compared to public airports, private airports may restrain their supply of peak slots strictly below their capacity levels when they serve airlines that compete to the same destinations. Such an inefficiency takes place in airports that have low per-passenger charges and are not too busy. It does not occur in the absence of competition in destination markets.     

City-Pairs Versus Airport-Pairs: A Market-Definition Methodology for the Airline Industry

This paper provides a methodology for deciding which airports warrant grouping in multi-airport metropolitan areas. The methodology is based on the comparability of incremental competition effects from nearby airports on average fares at a metropolitan area’s primary airport. Results from a quarterly panel data set for the period 2003–2009 provide strong evidence that city-pairs, rather than airport-pairs, are the appropriate market definition for analyses of passenger air transportation involving many (but not all) large metropolitan areas. Based on the proposed method, we offer a recommended list of airports that should be grouped when creating city-pairs for the analysis of competition in the US domestic airline industry.     

Airport deregulation: Effects on pricing and capacity

We use a model of vertical relations between two congestible airports and an airline oligopoly to examine, both analytically and numerically, how deregulation may affect airports prices and capacities. We find that: (i) unregulated profit-maximizing airports would overcharge for the congestion externality and, compared to the first-best, would induce large allocative inefficiencies and dead-weight losses. They would restrict capacity investments but, overall, would induce fewer delays; (ii) Welfare maximization subject to cost recovery performs quite well, achieving congestion levels similar to a private-unregulated airport but without inducing such large traffic contraction; this puts a question mark on the desirability of deregulation of private airports; (iii) Increased cooperation between airlines and airports provides some improvements, but the resulting airport pricing strategy leads to a downstream airline cartel; (iv) When schedule delay costs effects are strong and airline differentiation is weak, it may be optimal to have a single airline dominating the airports, but this happens only when airports' pricing schemes render the number of airlines irrelevant for competition.     

Airports and Economic Development

This article tests whether the activity at a metropolitan area's airport helps predict population and employment growth. In regression equations explaining employment and population growth, the article uses various measures of airport activity, including boardings, originations, hub status and cargo volume. Because airports may be a function of, as well as a cause of, growth, the article instruments for airports by using geographical and lagged variables. It finds that, under a variety of specifications, passenger activity is a powerful predictor of growth; cargo activity is not.     

Market share and price determination in the contemporary airline industry

This paper examines airline pricing and market structure determination for domestic airport-pair routes. The model includes variables to control for the effects of congestion, consumer brand preferences, barriers to entry into airports, and multiple airport availability within a city. The results indicate the noncontestability of airline markets, but certain factors can mitigate a carrier's endpoint dominance. Additionally, the need for policies addressing airport congestion is indicated by several aspects of model results.     

Opting Out,Collective Contracts and Labour Flexibility: Firm-Level Evidence for The Italian Case

This article analyses the role of deviations from higher level collective agreements adopted in firm-level bargaining to regain higher labour mobility, net positive employment effects and a resurgence of labour productivity. Using Italian firm-level data, after performing preliminary pooled ordinary least squares and fixed effects estimates, we adopt a difference-in-difference approach combined with a propensity score matching. All the estimations show that opting out clauses notably increases both hiring and separations, but without significant variations in terms of net employment. In addition, no significant labour productivity gains are obtained. The only significant change concerns the increase in the share of temporary workers.

The Impact of Middle Manager Training on Productivity: A Test on Italian Companies

This paper presents panel evidence on the productivity effects of middle managers’ off‐the‐job formal training in Italy. It is based on a rich and reliable panel dataset covering all sectors of the Italian economy over the period 2006–2011. We employ panel data techniques and self‐selection models to show that off‐the‐job formal training for middle management has a significant nonlinear exogenous effect on total factor productivity. Moreover, results indicate that middle managers’ off‐the‐job formal training is more effective in larger firms and that different training methods have heterogeneous effects on productivity.     

Issues and strategies in ex-post evaluation of intervention against animal disease outbreaks and spread

Animal disease outbreaks pose a significant threat in terms of potential economic losses, reduced productivity, and negative impacts on public health, food security and nutrition. This paper considers four issues in ex-post evaluation of animal disease interventions: firstly, a counterfactual involves simulating disease trajectories without the intervention. But some diseases can become endemic or become dormant after an outbreak, making it a challenge to know the true trajectory without the intervention. Secondly, without adequate design of controls and treatments, how can the estimated impacts be attributed to a given intervention? Thirdly, how do we assess costs saved by the intervention? Fourthly, given data uncertainty, would a stochastic simulation give better estimates than a deterministic one in solving for key variables? This paper addresses these issues and proposes solutions that bridge the gap between household level analysis and macro-level simulations in modelling the impact of animal diseases outbreaks.     

Human Resource Management and Corporate Performance in the UK

The relationship between HRM and performance was explored in 366 UK companies using objective and subjective performance measures and cross‐sectional and longitudinal data. Using objective measures of performance, greater use of HRM is associated with lower labour turnover and higher profit per employee but not higher productivity. After controlling for previous years’ performance, the association ceases to be significant. Using subjective performance estimates, there is a strong association between HRM and both productivity and financial performance. The study therefore confirms the association between HRM and performance but fails to show that HRM causes higher performance.     

Ultra-fast broadband access and productivity: Evidence from Italian firms

We study the impact of ultra-fast broadband (UFB) infrastructures on the total factor productivity (TFP) and labor productivity of firms. We use unique balanced panel data for the 2013–2019 period on incorporated firms in Italy. Using the geographical location of the firms, we merge firm-level data with municipality-level information on the diffusion of UFB, which started in 2015. We derive consistent firm-level TFP estimates by adopting a version of the Ackerberg et al.’s (2015) method, which also accounts for firm fixed effects. We then assess the impact of UFB on productivity and deal with the endogeneity of UFB by exploiting the physical distance between each municipality and the closest optical packet backbone node. Our results show an overall positive impact of UFB on productivity. Services companies benefit the most from advanced broadband technologies, as do firms located in the North-West and South of Italy. We further decompose the impact of full-fiber networks from mixed copper-fiber connections and find that the former significantly contribute to enhancing firm productivity. Finally, by exploiting Labor Force Survey data, we provide suggestive evidence that productivity increases from UFB might be related to structural changes at the workforce level.     

Tax breaks for incentive pay,productivity and wages: Evidence from a reform in Italy

This paper analyses the impact of a tax break on incentive pay (introduced in Law n. 208/2015) on labour productivity and average wages in Italian firms. We use a unique source of firm-level information drawn from a large representative survey of Italian firms merged with the ORBIS archive. By applying difference-in-differences methods, we obtain the following results. First, the tax break has a positive effect on both labour productivity and average wages, although the positive effect on average wages is not confirmed by robustness tests. Second, productivity impacts are mainly driven by family firms in northern regions, where firms benefit from the more dynamic business environment in which they operate. These results take into account unobserved heterogeneity and endogeneity issues.     

Performance Appraisal Systems: Determinants and Change

Using establishment data from the Australian Workplace Industrial Relations Survey, this paper estimates the determinants of performance appraisal systems. The results indicate that performance appraisal is associated with workers having shorter expected tenure and greater influence over productivity. We argue these results reflect those circumstances in which the net benefits of performance appraisal are likely to be greatest. The results also show that complementary human resource management practices, such as formal training and incentive pay, are associated with an increased likelihood of performance appraisal, but that union density is associated with a reduced likelihood of performance appraisal.     

Flexible Wage Contracts,Temporary Jobs,and Firm Performance: Evidence From Italian Firms

This study focuses on the effects of decentralized wage schemes and temporary forms of employment on firm performance. The effect of monetary incentives on workers' effort and firm performance is a central topic in economics. According to the principal‐agent paradigm, firms (the principal) have to link employees' remuneration schemes to any verifiable indicator of performance to avoid opportunistic behavior. The empirical evidence shows that financial incentives have the potential to exert strong effects on indicators of firm performance, such as productivity and worker absenteeism, although the degree of effectiveness of such schemes varies significantly according to the institutional/economic context in which firms operate. From both a theoretical and empirical point of view, the prediction on the effects of temporary types of employment on effort and productivity is less neat. In light of these considerations, this study uses a sample of Italian firms to provide further empirical evidence on whether and to what extent performance‐related pay schemes and contract flexibility affect workers' effort (in terms of absenteeism) and, in turn, firm productivity. These effects are analyzed for different types of workers (white collar vs. blue collar), working in workplaces characterized by a different degree of uncertainty and risk and in firms operating in different economic and institutional settings. Our results show that wage flexibility has a significant effect on effort and then on firm's productivity and that white‐collar workers are more responsive to monetary incentives than blue‐collar workers. Moreover, the presence of a large share of temporary contracts, implying a lower dismissal probability for permanent workers and a deterioration of the working environment, appears to reduce workers' motivation and effort.     

Lower Bound Estimation – Quantile Regression and Simplex Method: An Application to Italian Manufacturing Sectors

This paper estimates Sutton's lower bound [1991, 1998] by quantile regression, and thus shows the influence of outliers on previous estimates that used the simplex method. The lower bound estimates are obtained separately for exogenous and endogenous sunk cost industries in Italian manufacturing sectors in 1995, using microdata from the SCI'95 (Firms Accounts System) survey conducted by ISTAT (National Institute of Statistics, Italy). The results suggest that Sutton's predictions are robust.     

Business process reengineering of an air cargo handling process

Business Process Reengineering (BPR) is one of the most recent innovations in industrial engineering and management science which represents the rapid and radical redesign of strategic, value-added processes and the system, policies and organizational structures that support them to optimize the work flows and productivity of an organization. This paper presents a BPR effort and programme of an air cargo handling process at an international airport. The objective of this work is to demonstrate the performance breakthrough of a BPR technique to achieve dramatic improvements in critical measures of contemporary performance with respect to quality service and speed in the airlines cargo handling process. Field data on service dimensions of the process have been collected choosing time as metric. Process-flow diagrams, process analysis worksheets and data summary charts are prepared as effective tools to get a thorough understanding of the existing process with a view to focus on the possible areas of improvements. A fact-based defensible and quantifiable “Before–after chart” of BPR has been presented for documenting the expected gains. BPR has proved to be a modern innovative useful industrial engineering and management technique to achieve dramatic improvement in operational efficiencies for quality services of the airlines cargo handling processes.     

Internal Wage Structures and Organizational Performance

This paper considers whether a hierarchical or compressed wage structure is positively associated with relatively high levels of organizational performance. To date, there has been little empirical research in this area (especially in the UK). Thus we present an operational measure of a compressed/hierarchical wage structure, using UK manufacturing micro–data in five industrial sectors, and examine its relationship with labour productivity. We find that the wage compression argument holds in one sector but not for the majority of sectors and that taking into account other, intra–industry characteristics, namely size and ownership differences, further weakens the relationship.     

Works Councils and Unionization: Lessons from South Korea

This study analyzes the impact of effective works councils and unions in large South Korean firms. Following a brief review of economic theory on works councils and the institutional environment of Korean industrial relations, we describe the unique data set used to analyze Korean firm-level labor relations and economic performance. The results of the multivariate analysis show that both effective works councils and unions enhance employee voice on several key personnel practices. In addition, the estimates show that unionization increases wages and reduces turnover, but effective works councils are associated with higher levels of employee satisfaction and somewhat higher productivity. These estimates are consistent with theoretical models that find that carefully designed works councils can enhance employee voice and may increase productivity.     

Profitability, productivity and price recovery patterns in the U.S. telecommunications industry

We undertake a study where we examine changes in the profitability, productivity and price recovery of firms in the U.S. telecommunications industry over a sixteen-year period. We assess the performance of thirty-three major companies in the local-exchange sector over six time periods 1975, 1978, 1981, 1984, 1987 and 1990, using a performance analysis model which disaggregates the profitability measure into two components: productivity and price recovery. We demonstrate the computation of performance using this technique. Our study indicates that the opening up of markets has had a significant impact on different dimensions of performance in the telecommunications industry, also validating a number of theoretical assumptions about the impact that industry changes are expected to have on firms.
