Ten years after bus deregulation in Japan: An analysis of institutional changes and cost efficiency

The local bus market in Japan was deregulated in 2002. This study examines the impact of this deregulation on the market structure and the operators' cost efficiency over the last ten years. First, we perform a qualitative before-and-after-deregulation analysis of Japan's bus market, finding that there has been little change in the structure of the Japanese bus market so far. Second, we investigate the effectiveness of the deregulation and internal organisational factors by using a dataset of publicly owned (municipal) bus companies. We estimate the total cost frontier functions in order to examine their effects, showing that it is the internal organisational factors (i.e. governance structure) that affect the operator's efficiency, not deregulation. In fact, the coefficient of subsidies to companies is positive, with statistical significance, thereby suggesting that cost efficiency decreases as the subsidy ratio increases. The coefficient of the contracting-out (MCGL) dummy also obtains statistically significant results; thus, we provide an account of how contracting out clearly improves operators' cost efficiency. The deregulation variable did not show significant results.     

The regulatory function in public-private partnerships for the provision of transport infrastructure

A wide range of contractual arrangements are increasingly being used by the public sector to materialise the delegation of transport infrastructure provision tasks to the private sector, over long periods of time. This paper addresses the issue of transport infrastructure regulation in the specific context of public-private settings. Starting by the discussion on the concept of Public-Private Partnership (PPP) it is stressed that, despite the different meanings that can be found in the literature, it is possible to define a PPP by using a core group of characteristics, such as the bundling of services and the transference of a relevant part of the risks to the private sector on a long term basis. Regarding the action of the regulator, we look at three dimensions of efficiency that are expected to be pursued at the strategic level of regulatory action. However, it is acknowledged that the regulatory function is in practice rather complex since it requires balancing a multiplicity of other objectives or goals, which may vary according to specific economic conditions. In the domain of pricing, the review carried out suggests that since “first best” assumptions are not met in the “real world” it hardly seems possible that the short run marginal cost pricing “canon” could be directly used to shape pricing policies. Consequently, when considering the application of the standard neoclassical marginal cost pricing approach it is pertinent to ask whether the second best solutions can lead to efficient outcomes that might be accepted by the stakeholders. Bundling construction and maintenance tasks into a single long term contract, which is a typical characteristic of “standard” PPPs, could theoretically bring cost benefits since it allows for the possible internalization of any positive externalities that may be generated during the whole project life cycle. The economic rationale for the bundling of construction/maintenance with financing services is that it enhances the likelihood of submission of realistic bids at the procurement stage. In addition, the chances of the contractor sticking to the agreed contractual terms, after contract award, are potentially increased given the higher exposure to financial risk.     

Regulating the regulator: The impact of professional procuring bodies on local public transport policy and its effectiveness

During the past 15 years competitive tenders have become a common procedure when procuring local bus services in Europe. In particular, tenders with gross cost contracts and the so-called Scandinavian model have gained popularity, resulting in a vast amount of research on optimal contractual relationships between government and operators. This paper pays attention to a rather neglected part of the Scandinavian model: the construction of professional procuring bodies and their relationship to the local public administration, focusing on its implications for policy steering and service performance.The paper outlines briefly two different perspectives of analyses of organisational models: one perspective is anchored in principal-agent theory and institutional economics; and the other perspective in political science. Empirically, the article is based on an evaluation of the relation between two Norwegian counties and the administrative company responsible for planning and procuring public transport services. This evaluation indicates, firstly, important common challenges for the county administration due to lack of regional administrative competencies in relation to the administrative company, which also hampers the county’s role as coordinator of policy areas of importance for public transport. Secondly, due to increased transaction costs, the establishment of administrative companies does not seem compatible with contracts relying on net cost solutions with huge scope for operator initiatives.     

Paying for performance: Uncertainty, asymmetric information and the payment model

Privatisation has led to a growing interest in more complex contractual forms designed to give public transport operators the incentives for effort that maximise value for money. Contract theory provides a rich research basis for selecting an appropriate contractual form, with an emphasis on the effects of uncertainty and asymmetric information. To date, however, there have been few applications of contract theory in the field of transport. This paper identifies the key empirical results from the multi-disciplinary literature to help transport researchers and practitioners place contractual decision-making in the broader theoretical context, suggesting aspects of transport contracting that merit future research.

Is the bus transport contracting system in South Africa leading to trusting relationships between contracted parties? An analysis of funding issues and the impact on relations between government and operators

The 1996 South African White Paper on National Transport policy provided the guidelines for the restructuring of the commuter bus industry. The restructuring objectives were based on improving the competitiveness of and service levels within the industry through a competitive tendering regime, the selective implementation of negotiated contracts and the general transformation of the industry to also include improved transparency in the funding arrangements between government and operators.In order to set the context of the paper, a brief overview is provided of the progress made with policy implementation and the background to funding issues that are experienced in the bus transport sector. To gauge the impact of the funding issues on the relationship between government and operators, a survey of the largest contracted operators was undertaken to determine, amongst other, how these funding issues have potentially impacted on trusting relationships between contracted parties.     

Lessons in ownership, regulation and management from 100 years of bus transport in Sri Lanka

Sri Lanka observes 100 years of bus passenger transport in 2007. During this period the country has seen different forms of service providers ranging from private sector monopolies to state sector monopolies. It also has seen several changes in state policy ranging from welfare orientated service provision to entire market determined without any regulation. The existing regulated mixed competition is also characterized by poorly equipped regulators. In conclusion, the paper traces the different stages of failure that have led to the poor quality of bus transport services existing at present.     

Incompleteness and clarity in bus contracts: Identifying the nature of the ex ante and ex post perceptual divide

In the transport sector, many types of contracts exist. Some are very precise, and strive for completeness; others are very ‘light-weight’ and are incomplete. Bus and coach contracts, won through competitive tendering or negotiation, are typically incomplete in the sense of an inability to verify all the relevant obligations, as articulated through a set of deliverables. This paper draws on recent experiences in contract negotiation, and subsequent commitment in the bus sector, to identify what elements of the contracting regime have exposed ambiguity and significant gaps in what the principal expected, and what the agent believed they were obliged to deliver. We develop a series of regression models to investigate the extent of discrepancy between the principal and the agents perceived ‘understanding’ of contract obligations. The empirical evidence, from a sample of bus operators, is used to identify the extent of perceived incompleteness and clarity across a sample of bus contracts. A noteworthy finding is the important role that a trusting partnership plays in reducing the barriers to establishing greater clarity of contract specification and obligations, and in recognition of the degree of contract completeness.     

Comparing operator and users costs of light rail, heavy rail and bus rapid transit over a radial public transport network

A model to compare three alternative forms of public transport - light rail, heavy rail and bus rapid transit - is developed for an urban network with radial lines emanating from the borders to the city centre. The theoretical framework assumes an operation aimed at minimising the total cost associated with public transport service provision, which encompasses both operator and users costs. The decision variables are the number of lines (network density) and the frequency per period for each mode. This approach has no prejudices a priori in respect of whether a specified delivery scenario is aligned with existing modal reputation. Rather, we establish the conditions under which a specific transit mode should be preferred to another in terms of the operator (supply) and user (demand) side offerings. The model is applied using data from Australian cities, suggesting that in most of the scenarios analysed a high standard bus service is the most cost-effective mode, because it provides lower operator costs (infrastructure, rolling stock and operating cost), access time costs (due to a larger number of lines) and waiting time cost (due to larger frequencies of operation). A rail mode, such as light rail or heavy rail, may have a lower total cost only if it is able to run faster than bus rapid transit, and the difference in speed is enough to outweigh the bus advantage on operator cost and access and waiting times.     

Regulation,trust and contractual incentives around transport contracts – Is there anything bus operators can learn from public air service contracts?

This paper compares recent experiences in contract negotiation and subsequent commitment in public air services with the bus industry. The heart of the paper is a survey of European and Australian regional airlines, which we mirror with revealed experiences of bus operators. We aim to identify a number of elements in the contracting regimes that have exposed ambiguity and significant gaps in what the principal (e.g., transport department) expected, and what the agent (airline or bus operator) believed they were obliged to deliver. Ultimately airline and bus services are similar in that public authorities procure transport services that are desirable for the society but would be unprofitable without government involvement. In both sectors (theoretically fairly similar) public transport contracts are used, and those usually include obligations and performance measurements. In terms of similarities, one of the surveyed contract details that had a perceived high clarity in both industries was “payment procedures” and amongst those with rather poor clarity was also in both industries “incentives to improve performance and grow patronage”. We also show differences between regional air services and bus operations with regard to performance measurement and pre-specified obligations. Because of the strong safety culture around air services we find that regulation and trusting partnerships are even more important to aviation than to the bus sector. Because of the high level of trust but also because of simpler and more complete contracts in aviation, there is much less (re-)negotiation going on compared to the bus operations.     

Competition in Brazilian bus and coach services - The results of recent competitive tendering processes

This paper analyses the terms and the results of a sample of some recent Brazilian bidding processes for the concession of public passenger transport services: namely, urban and metropolitan bus or regional coach services. The analysis is based on selected issues relating to competitiveness and upon the legal framework that applies in this sector. It was concluded that, given the lack of bidding processes for concessions in the bus and coach sector in Brazil, the fact that some bidding processes have been carried out should be considered a sign of progress. However, these auctions have not necessarily prioritised competitiveness, since many barriers to entry into the systems were imposed by the bidding terms. Future competitive tendering processes should seek to abide by stricter principles of competitiveness, if they wish to avoid the entire effort expended on conducting such processes serving only to mask nothing more than formal obedience to the law and to discredit the bidding process in the eyes of Brazilian citizens.     

Overview of public transport policy developments in South Africa

Public transport in South Africa is one of the most burning issues in the transport sector. The government is faced with huge public pressure to improve public transport systems in the face of rising fuel costs, the pending implementation of expensive urban toll road systems in the Gauteng province, and elsewhere in urban environments, public transport safety issues, public transport fleet renewal, especially the commuter rail services, as well as limited resources to fund public transport. As a developing country, the South African Government has pressing funding issues such as funds needed to improve housing for the poor to improve schooling and public health services. Government is also faced with a vocal minibus taxi industry that transports an estimated 65% of all commuters in the country that is also insisting on subsidies for its services.     

Sustainable procurement and environmental life-cycle costing in maritime transport

Transportation sector, including maritime transport, exerts significant environmental impact. Public procurement as a policy strategy instrument which applies to the purchase of transport means, construction of infrastructure and the provision logistic services in supplying the goods, services and executing of works must integrate environmental considerations in the contract award procedures. While conventional life-cycle costing (LCC) is based on four categories to be assessed e.g. investment, operation, maintenance and end-of-life disposal expenses, the environmental LCC method also takes into account the external environmental costs. The paper is focused on sustainable public procurement and environmental life-cycle costing aspects of EU 2014 Directive. Analysis is made of the real cost of procurement, the externalities and the impact of maritime transport sector on the environment. The purpose of this research is to propose the framework for assessment of integral impact on the environment which combines environmental LCC approach with TBL concept using non-monetary units for measuring externalities. The authors advocate clean and energy-efficient maritime transport ensuring effective implementation of environmental policy objectives and targets and emphasize the role of public authorities and entities in fostering the inclusion of environmental externalities in calculation of LCC.     

Overview of public transport policy developments in South Africa

In South Africa, a restructuring of the public transport system is currently under way. In the bus industry the tender for contract system is being implemented, the commuter rail sector is being recapitalised and the minibus taxi industry recapitalization programme is in its early stages. Progress with policy implementation across the modes of transport, modal split trends and issues that hamper the full development of the public transport industry are discussed in this paper. Medium to long term policy and strategy initiatives that will further inform the development of the industry are also highlighted in this chapter.     

Part I: Externalities and economic policies in road transport

Road transport imposes negative externalities on society. These externalities include environmental and road damage, accidents, congestion, and oil dependence. The cost of these externalities to society is in general not reflected in the current market prices in the road transport sector.An efficient mobility model for the future must take into account the true costs of transport and its regulatory framework will need to create incentives for people to make sustainable transport choices. This paper discusses the use of economic instruments to correct road transport externalities, but gives relatively more weight to the problem of carbon emissions from road transport, as this is particularly challenging, given its global and long-term nature.Economics offers two types of instruments for addressing the problem of transport externalities: command-and-control and incentive-based policies.Command-and-control policies are government regulations which force consumers and producers to change their behaviour. They are the most widely used policy instruments. Examples include vehicle emission and fuel standards in the US as well as driving or parking restrictions in Singapore. The implementation cost of these instruments to the government is small. Although from an economic perspective these policies often fail to achieve an efficient market outcome, the presence of political constraints often make them the preferred option, in terms of feasibility and effectiveness.Economic theory shows how policies, which affect consumption and production incentives, can be used to achieve the optimal outcome in the presence of externalities. Incentive-based policies function within a new or an altered market. We first examine incentive-based policies, which cap the aggregate amount of the externality, such as carbon emissions, by allocating permits or rights to the emitters. The emitters are then free to trade their permits amongst them. The permit allocation mechanism is important-although market efficiency would be satisfied by an auction, political influences usually favour a proportional allocation based on historic emissions. We discuss EU ETS as an example of a cap-and-trade system, however, no such policy for CO₂ emissions in road transport has been implemented anywhere in the world to date.Fiscal instruments are, like command-and-control, widely used in road transport, because they are relatively cheap and simple to implement. They include the use of taxes and charges in order to bridge the gap between private and the social costs and, in principle, can lead to an efficient market solution. Registration, ownership, fuel, emissions, usage taxes, and parking and congestion charges have been implemented in many countries around the world. On the other side of the spectrum, subsidies can be given to those scrapping old cars and buying fuel-efficient vehicles. Some cities, such as London, have implemented congestion charges and many states in the United States have introduced high occupancy lanes. Other interesting possibilities include pay-as-you-drive insurance and other usage charges. However, the size and scope of taxes and subsidies are determined by governments, and because of their imperfect knowledge of the market the outcome is still likely to be inefficient.Governments have many effective economic instruments to create a sustainable road transport model. These instruments can be used separately or together, but their implementation will be necessary in the nearest future.     

Public transit subsidies, output effect and total factor productivity

This paper extends previous works on total factor productivity decomposition when firms receive both operating and capital subsidies. It shows that previous works considered either the lump-sum or substitution effects of these subsidies but not together. Using constrained cost minimization as the framework it offers formal proofs to show that cost increases are inevitable if the total effects of the subsidies are considered, and that total factor productivity growth results from increasing amounts of subsidies under economies of scale and in the absence of technical change. Applications of the decomposition equations derived to a sample of transit systems finds near constant returns to scale and negative contributions of these subsidies to total factor productivity growth. Technical change reverses this decline and results in total factor productivity growth. Further, it finds that the lump-sum effects of the subsidies reduce total factor productivity more than does the substitution effect.     

Programming, optimal pricing and partnership contract for infrastructures in PPPs

The development of various forms of public-private partnerships for the financing, building and operating of public infrastructure has not fundamentally altered the economic calculations involved. This chapter examines to what extent it is necessary, however, to change the way that government uses socio-economic and financial evaluations, whether to optimise investment programming or pricing. Ensuring a coherent match between these two types of optimisation can provide a principle for determining the optimal programming price.We begin by showing that when projects are financed by both users (toll revenues) and taxpayers (subsidies), it is socially beneficial to plan these investments on the basis of the net present value (NPV) provided by each unit of public money invested. This NPV/subsidy ratio must obviously be higher than the public-funding scarcity coefficient or else the investment would destroy more wealth than it would produce.One of the ways of improving this ratio is also to optimise the toll level, since increasing it can lower the subsidy but has an adverse impact on the user surplus, it is essential to set the optimal toll.In the case of an approved project considered in isolation, we show that the optimal toll depends upon the public-funding scarcity coefficient. If there is no scarcity, the optimal toll is zero. As public-funding becomes scarcer, the optimal toll draws closer to the toll that optimises revenue.In the case of a programme of several projects subject to budget constraint, we show that the optimal toll no longer depends upon the public-funding scarcity coefficient and that there are several scenarios depending on the relative values of the maximum revenue and the total cost of the project:

−

when, whatever the toll, revenue can no longer cover over half of the cost, it is socially beneficial to choose not to levy any toll;

−

when there is a toll that covers the total cost, the operator may be left free to set it at the level he sees fit, with the issue of how the profits are to be shared between the franchisee and the franchisor being settled separately;

−

when the maximum revenue of the project falls between half and all of the total cost, the value of the toll that maximises the welfare function is lower than the revenue-maximising toll and must therefore be set for the private operator by government.

Thus, the partnership contract must be given a different content in these three cases of optimal pricing.

Preamble

Most of the theoretical studies devoted to optimising public investment programming and infrastructure pricing have, since the work of Jules Dupuit (1844), focused on the salient issues of the transport sector, even though this work was relevant to all sorts of public infrastructure. The analysis presented in this paper deals with transport economics, but in line with this tradition, is also applicable to any field in which public-funding is combined with commercial revenue. For example, the question of determining how the financing of an opera should be shared between taxpayers and opera-goers raises the same type of issues as the optimal combination of tolls and subsidies for financing a motorway project. This report will be focused on these issues. We shall see that certain precautions are called for in investment programming together with some new thinking on pricing principles.     

Contracting regimes for bus services: What have we learnt after 20 years?

This paper reviews a number of themes that have played a crucial role in the debate on alternative contracting regimes for the provision of urban bus services. We have selected four crucial issues to reflect on: (i) contractual regimes (in particular competitive tendering as compared to negotiated performance-based contracts, as means to award the rights to provide service); (ii) contract completeness (focussing on ex ante and ex post elements); (iii) building trust through partnership; and (iv) tactical or system level planning for bus services. Experience in these areas suggests that competitive tendering has frequently not lived up to expectations and that negotiation is likely in many circumstances to deliver better value for money.     

Workshop 2: Bus rapid transit as part of enhanced service provision

Workshop 2 focused on the role of BRT as part of enhanced public transport service provision. Discussion topics included case studies around the world; improved performance and operations; and better contracts, institutional settings and enhanced policies. BRT was identified as a vital component of modern public transport systems due to its ability to provide high performance and rapid implementation at a lower cost than comparable rail transit. The participants concluded that on top of improving trunk transit corridors, it is important to look to the first and last kilometers and the connections among transport modes. In addition, it is important to consider all dimensions, not just the technical issues. The workshop identified the desirable ingredients for BRT success, created a table of bus based options for different applications and a list of research topics.     

Technology Choice and Productivity in the Turkish merchant fleet in the last two decades

Sea transportion has become a significant sector in Turkey since the early 1980s. It has developed due to the domestic subsidies provided and also because of the favourable conjuncture in the world ship Sale and Purchase markets in this period. In the 1990s this sector has started to gain some self-confidence and has completed the 'Infant Inudustry' period. However, bacause its structure is open to international competition, the protection policies available in the 1980s have been found to be inadequate. The capacity of the Turkish merchant fleet has expanded to a considerable extent in the last two decades, but it is comprised of over-aged and old fashioned ships built using outdated technology. and a sudden and cat-astrophic crisis could be approaching. A precaution in the long run could be to have special types of ships carrying convenient loads at minimum costs.
