Discriminatory Dealing with Downstream Competitors: Evidence from the Cellular Industry

One concern about regulated monopolies entering unregulated vertically-related markets is that they will discriminate against competitors of their unregulated affiliates. However, prohibiting regulated monopolies from offering related goods may preclude production by the most efficient provider. We take advantage of variation across geographic cellular phone markets in the US to examine the effect of integration on output, quality and prices. We find some evidence consistent with efficiencies (greater concentration of lines to users is associated with greater output and higher quality) and some consistent with discrimination (greater interconnection facility ownership concentration is associated with lower output and quality).     

Production Efficiency and Discriminatory Hiring Practices in the National Hockey League: A Stochastic Frontier Approach

This paper studies the production process in the National Hockey League (NHL) and attempts to identify the sources of production inefficiency, including potential inefficiencies associated with preferences for, or against French-Canadians. Employing the method of stochastic frontier estimation, it is shown that production inefficiencies are prevalent in the NHL and can, in part, be traced to differences in coaching ability, team ownership, local sports competition, and management experience. In addition, it is found that teams with unusually high (or low) numbers of French-Canadian players tended to be less efficient, implying that discriminating hiring practices are costly.Jel Classifications: D21, J71, L83     

Trade Unions and Productivity: The German Evidence

This paper provides a brief review of the empirical evidence on union productivity effects in Germany. The influence of trade unions on productivity is the net effect of conflicting forces which can lead to higher or lower productivity. Although the German dual system of workers' representation via unions and works councils is quite favourable to the existence of productivity-enhancing 'voice' effects, various empirical studies have not been able to detect significant positive net effects of these institutions on productivity.     

Unions and the Employment Growth: Panel Data Evidence

This study adds to the small empirical literature on the impact unions have on employment growth using data from Australia. Unlike previous studies, the data used are from a panel of firms surveyed at two points in time rather than a single cross section. The results indicate a negative union effect on employment in private-sector firms of about 2.5 percent per annum that, despite the very different institutional framework that prevails in Australia, is consistent with results obtained with North American data.     

Unions and Collective Bargaining in the Wake of the Great Recession: Evidence from Portugal

Against the backdrop of its industrial relations architecture, characteristic of the ‘southern European group’ and intimately linked to the recommendations of the Troika, this paper examines four key aspects of Portuguese collective bargaining. First, it provides definitive estimates of private sector union density for that nation. Second, it models the determinants of union density at firm level. Third, it yields estimates of the union wage gap for different ranges of union density. The final issue examined is contract coverage. The received notion that the pronounced reduction in the number of industry‐wide agreements and extension ordinances of late is to be equated with a fall in coverage is shown to be a chimera, the number of workers covered by new and existing agreements remaining largely unaffected by the economic crisis. The reduced frequency of new agreements and extensions is instead attributed to downward nominal wage rigidity in low‐inflation regimes.     

An investigation into the mixed reported adoption rates for ABC: Evidence from Australia, New Zealand and the UK

An accumulated body of the literature confirms that the adoption of activity-based costing (ABC) can lead to a substantial improvement in organisational performance, productivity and profitability, and therefore encourages further adoption of the technique. However, studies investigating the diffusion of ABC have reported inconsistent and mixed results. This could cause uncertainty for many potential adopters of ABC (especially for those who follow the fashion and fads approaches) and influence their tendencies towards the adoption of ABC in the future. Addressing the diffusion process as a contextual factor, this study simultaneously investigates the adoption of ABC from the perspectives of different diffusion processes. Using two commonly adopted diffusion processes (the stages of adoption and the levels of adoption), this study examines the relationship between the reported adoption rates for ABC and the diffusion process approaches chosen to measure its adoption rates in three western countries: Australia, New Zealand and the UK. A similar questionnaire was used and more than 2000 qualified CIMA members (via a survey study and follow-up interviews) were targeted. The findings suggest a significant association between the reported adoption rates for ABC and the diffusion process approaches chosen to measure the adoption rates. The findings further suggest that the lack of a common understanding of ABC systems may have also contributed to the mixed reported adoption rates for ABC, as many ABC adopters have considered themselves adopters of traditional accounting systems by mistake (especially when they are dealing with ‘facility costs’ as one of the main cost hierarchies under ABC systems).     

New Firms' Survival and Market Turbulence: New Evidence from Spain

The availability of longitudinal data for individual firms has allowed the improvementof the existing knowledge on market structure dynamics. We present additional evidence through the analysis of a cohort of Spanish manufacturing firms. Our results confirm some basic empirical findings obtained in studies for other countries. According to the behavior of the cohort we study, Gibrat's Law does not hold for new entrants. Patterns of market turbulence vary considerably according to the type of industry. The behavior of new firms seems to fit the learning model. The estimation of a hazard function demonstrates that the main regularities affecting the likelihood of survival of young firms are quite similar in different types of countries.     

The Effect of Trade Unions on the Provision of Training: Australian Evidence

This paper uses data from the Australian Workplace Industrial Relations Survey conducted in 1989–90 to examine the net impact of trade unions on the extent of formal types of employer-provided training. A net positive effect is found, but only where unions are active in the workplace and not merely de jure representatives of the work-force. The results also indicate, with respect to in-house training, that unions shift the emphasis towards work-forces with long tenure, a finding that is consistent with 'union voice' arguments.     

Have Unions Turned the Corner? New Evidence on Recent Trends in Union Recognition in UK Firms

This paper reports results from a recent survey conducted on unionization in over 650 firms in the private sector in the UK. The survey shows that since 1997 there has been a slight fall in derecognition, but a relatively large increase in union recognition. This increase in new recognition agreements is consistent with the idea that the incoming Labour government had a positive effect on the ability of unions to gain recognition, either through the 1999 legislation or more indirectly through changing the political climate.     

The Productivity-Enhancing Impacts of the Minimum Wage: Lessons from Denmark and New Zealand

This article adds an international comparative perspective to the reflection on 100 years of minimum wage legislation in Britain by exploring the impact of minimum wage regulations and institutions in Denmark and New Zealand. In particular, it looks at the question of whether minimum wages can raise productivity through the 'shock effect'. It argues that while they will play a role, a supportive institutional framework is more important in providing coordinated solutions to issues of market failure, such as inadequate levels of training. The article suggests that sectoral bargaining institutions in low-paid sectors may have the potential to facilitate such coordination and enable the high-productivity model to emerge.     

新西兰电力改革的经验与教训

目前,新西兰人口约400万,最大电力负荷约600万kW,年用电量约400亿kWh,其中水电约占65%,其余为地热发电、天然气发电和煤电。在新西兰两大岛之间有一条直流输电线路,输送容量约100万kW。水电站多位于南岛,水库为大型天然湖泊,蓄水量大约相当于年用电量的15%。如果遇到干旱年,蓄水量会迅速下降,在两个月左右的时间内就可以从满蓄放空。     

Efficiency and Firm Ownership: Some New Evidence

The paper investigates the effect of state ownership on efficiency of firmsusing an econometric model that allows for the separation of technical from allocative efficiency in adynamic setting. The estimation results, based on a sample of international airlines, suggest that state ownershipis associated with lower technical and allocative efficiency. State ownership's effect on technical efficiencyis mainly a dynamic one – lowering the rate of cost decline, whereas its effect on allocativeefficiency is static – raising the level of costs. Thus lower technical, rather than allocative, efficiency isthe main reason for state-owned firms to be less efficient than their private counterparts.     

Unions and Police Productivity: An Econometric Investigation

We examine the effect of unionization on police productivity in large U.S. metropolitan areas. We define police output in the context of a production function model that draws also on the crime literature. We estimate the resulting model using a data set that includes published and unpublished government statistics as well as our own survey of police departments. Results suggest that the effect of unions on police productivity varies according to categories of police performance. In particular, if performance is stratified according to the severity of crimes, unions seem to have an insignificant effect on police productivity with respect to serious crimes. For minor crimes, unionization alters the parameters of police production function, leading to diminished productivity.
