    Bypassing public procurement regulation: a study of rationality inlocal decision making2011Ingår i: Regulation and Governance, ISSN 1748-5983, E-ISSN 1748-5991, Vol. 5, nr 3, s. 368-385Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Using private contractors through procurement is common in most public sector areas. Despite the benefits of procurement, officials are sometimes tempted to circumvent procurement regulations. The aim of the article is to examine strategies used by local governmental decision makers to bypass procurement regulations, analyzing the rationality underlying their actions. Interviews, court documents, municipal documents, and articles describing the actions of Swedish municipal officials concerning special transport service (STS) procurements were collected and analyzed. In a case in which rural municipalities lost regular taxi services after STS procurement, we demonstrate how decisions were driven by pressure from the public and local interest groups, making municipal officials deviate from procurement regulations in striving to secure the existence of regular taxi services. One outcome was that local businesses were given preferential treatment, violating regulations and reducing economic efficiency.

    A strategy for increased public transport usage: The effects of implementing a welfare maximizing policy2014Ingår i: Research in Transportation Economics, ISSN 0739-8859, E-ISSN 1875-7979, Vol. 48, s. 221-226Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    For a long time public transport has experienced a struggle against rising costs and increasing car ownership. So far, public transport appears to be on the losing side in terms of market shares. The aim if this paper is to investigate if a different policy could result in higher public transport usage and improved social welfare. In order to achieve this, a model, explaining public transport usage, public transport supply and costs, is estimated. The model is then used in order to simulate the outcome of an alternative policy of social welfare maximization. It is found that the current policy of the Swedish transport is not efficient in terms of maximizing welfare. In 2011, public transport fares should have been lower in 20 of 21 counties and the supply of vehicle kilometres should have been higher in 17 of 21 counties. Implementing a welfare maximizing policy would have increased the number of trips per capita by 17.2% in 2011 and by an average of 6.7% for the period 1986-2011.

    An analysis of the determinants of local public transport demand focusing the effects of income changes2013Ingår i: European Transport Research Review, ISSN 1867-0717, E-ISSN 1866-8887, Vol. 5, nr 2, s. 101-107Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose: In order for public transport to be a part of the solution to the environmental problems caused by traffic, there need to be a clear understanding of how, and to whatextent, different factors affect demand. There still seem to be some confusion regarding some key relationships, one of them being the effect of income on public transport demand. The purpose of this article is therefore to provide empirical estimates of how different factors, including price and car ownership (although income being the main issue), affect the demand for local public transport.

    Methods: In order to achieve the aim of the study, an econometric FD-model, allowing for unobserved effects, was estimated using panel data from Swedish counties from1986 to 2001.

    Results: The short-run (direct) elasticity with respect to fare, vehicle-kilometres, income and car ownership were found to be −0,4, 0,55, 0,34, and −1,37 respectively. However, income affects public transport demand directly, and through its effect on car ownership, these effects works in opposite direction. Combining these, it is found that total income effect is close to zero.

    Conclusions: It is concluded that, although the findings of several previous studies suggests that demand for public transport might be falling with increased income, there is no evidence of such effects in this study even when the full effect of changes in income (including changes in car ownership) is taken into account.

    Demand and Supply of Public Transport: The Problem of Cause and Effect2005Ingår i: Competition and Ownership in Land Passenger Transport: selected refereed papers from the 8th International Conference (Thredbo 8), Rio de Janeiro, September 2003 / [ed] David A. Hensher, Sydney: Elsevier , 2005, s. 405-421Kapitel i bok, del av antologi (Övrigt vetenskapligt)
    Abstract [en]

    In 1989 the late Prof Michael Beesley and Prof David Hensher convened a workshop of an invitational group of academics, transport operators and government regulators to review and report on the recent reforms in the British bus sector. The workshop was held in Thredbo, Australia. At the time this was a once off activity. Its success was such that it spawned a series of biannual conferences (now known as the Thredbo series) held in Finland (1991), Canada (1993), New Zealand (1995), England (1997), South Africa (1999), Norway (2001), Brasil (2003) and Portugal (2005). The conference series attracts a unique mix of researchers and practitioners with the common aim to share their experiences throughout the world on topics related to the institutional reform of land passenger transport (especially bus, rail and ferry). The focus is on workshops and plenary sessions in which participants are engaged in intense discussions that lead to the production of workshop reports that set the agenda for reform for the next period between the conferences. In the past workshop reports have been published in a major international journal and selected papers in special issues of journals.The growing number of citations of the material from the thredbo series has motivated this book, providing an opportunity to bring together in one volume the best papers from the conference plus the workshop reports. All chapters have been peer refereed. The themes in this volume (the first in a new series) include competition and regulation, contract specifications (especially performance-based contracts), regulatory and planning tools, institutional frameworks, service quality and pricing and performance data and measurement. Within one volume we provide a comprehensive update and review of the reform programs throughout the world in the land passenger transport sector. The volume is edited by Professor David Hensher, co-founder of the series and a recognized world authority in the field. It is the most current global assessment of reforms in land passenger transport. It contains papers written by those who influence policy and institutional reform in over 20 countries. It presents a comprehensive statement of the successes and failures in public transport reform. Many of the authors are regarded as the leading authorities in the field.The case studies throughout the world are not available in any other single source.

    Demand and supply of public transport: The problem of cause and effect2005Ingår i: Thredbo 8, Rio De Janeiro, September 2003, Elsevier , 2005Konferensbidrag (Refereegranskat)
    Abstract [en]

    When modelling public transport demand vehicle-kilometres is often included among the explanatory variables and the possibility of a twoway relationship between the variables is often ignored. The purpose of this article is to examine the causal relationship between public transport demand and the supply of vehicle-kilometres. A granger causality test is applied to panel data from Swedish counties ranging from 1986 to 2001 and it is found that while vehicle-kilometres do cause patronage, patronage also cause vehicle-kilometres. Hence, there is a two way relationship between the variables that should be considered when estimating demand models.

    Estimating and evaluating the efficiency of public transport operations2011Ingår i: Thredbo 12 - Proceedings of the International Conference on Competition and Ownership in Land Passenger Transport: Performance measurement and compliance, 2011, s. 51-63Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    The aim of this study is to evaluate the efficiency of public transport operations undertaken in Swedish counties by the public transport authorities (PTA) taking into account the substantial differences in operating conditions between counties. The analysis will be performed through Stochastic Frontier Analysis (SFA) where yearly from 1986 to 2009 from 26 Swedish counties is used in order to estimate a cost frontier and analyse how the efficiency of the individual counties change over time. The results are used in order to provide a ranking (in terms of efficiency) of the Swedish public transport authorities that can provide a basis for benchmarking. It is concluded that the efficiency of the public transport providers fell in all counties during the observed time period. Defining cost efficiency as the ratio of minimum cost to observed cost, the overall (average) cost efficiency for the industry fell from 85,7 % during the eighties to 60,4 % during the period 2000 – 2009.

    Meta-analysis of public transport demand2007Ingår i: Transportation Research Part A: Policy and Practice, ISSN 0965-8564, E-ISSN 1879-2375, Vol. 41, nr 10, s. 1021-1035Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The present study uses meta-regression in order to explain the wide variation in elasticity estimates obtained in previous demand studies, and provide summaries of several bus demand elasticities.

    One important finding as to the price elasticity is that the often cited rule of thumb of −0.3 holds good if quality of service represented by vehicle-kilometres is treated as an exogenous variable, but not when it is treated as endogenous.

    Based on the results it is recommended that demand models should include car ownership, price of petrol, own price, income and some measure of service among the explanatory variables and that the service variable should be treated as endogenous.

    In previous meta-studies in this field focus has been on own price elasticity only while this study also includes elasticities with respect to, level of service, income, price of petrol and car ownership. The short run for the US are found to be −0.59, 1.05, −0.62, 0.4 and −1.48 respectively.

    Putting our money to good use: - Can we attract more passengers without increasing the subsidies?2009Ingår i: Proceedings of the Eleventh International Conference on Competition and Ownership in Land Passenger Transport: System Development, Delft, The Netherlands: The Next Generation Infrastructures Foundation , 2009, s. 121-134Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    The aim of this paper is to evaluate the policy pursued by Swedish transport authorities in order to determine if the number of trips made by local public transport could have been increased without increased subsidies. The evaluation is based on annual data from Swedish counties. It is found that between 1986 and 2001 public transport fares exceeded the passenger maximising fare most of the time in all but two counties. The average deviation ranged from 1 percent to 215 percent. The evaluation of  the alternative (passenger maximising) policy, including both fare and service changes, for 2001 showed that demand for local public transport in the Swedish counties could have been increased by 0 – 178 percent without increasing subsidies. Aggregated, this represents a 2,3 percent increase in trips made by local public transport in Sweden.

    Studies in Local Public Transport Demand2008Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [sv]

    Denna avhandling består av fyra artiklar där det övergripande syftet är att bidra till ökad förståelse av hur olika faktorer påverkar benägenheten att gör lokala kollektivtrafikresor. Ett genomgående tema i samtliga artiklar är att det sannolikt föreligger ett dubbelriktat samband mellan antalet resor som genomförs och mängden vagnkilometer som kollektivtrafikproducenten tillhandahåller. Detta eftersom kapacitet och kvalitet är intimt förknippade när det gäller kollektivtrafikutbud. Vid en given fordonsstorlek, innebär fler fordon i trafik att fler passagerare kan transporteras men också att väntetider och/eller avståndet till närmaste linje minskar, vilket utgör en kvalitetsförbättring.

    I den första artikeln undersöks det lokala kollektivtrafikresandet och vagnkilometerutbudet med hjälp av Grangers kausalitetstest. Syftet är att fastställa huruvida orsakssambandet dem emellan går från vagnkilometer till resande, från resande till vagnkilometer, eller om sambandet är dubbelriktat. Materialet som används kommer från svenska län och täcker perioden 1986 – 2001. Slutsatsen är att det föreligger ett dubbelriktat orsakssamband mellan variablerna.

    I den andra artikeln sammanställs resultat, i termer av elasticitetsskattningar, från tidigare studier av efterfrågan av lokal kollektivtrafik och variationen i dessa analyseras med hjälp av regressionsanalys, så kallad metaregression. Variationen kan delvis förklaras med modellspecifikation, typ av data som använts samt av geografiska skillnader.

    I den tredje artikeln estimeras en eftefrågefunktion för lokala kollektivtrafikresor med hjälp av data från svenska län. För att undvika problemet med det dubbelriktade sambandet mellan antal resor och vagnkilometer estimeras funktionen med hjälp av instrumentvariabler. Efterfrågeelasticiteter för lokal kollektivtrafik med avseende på pris, bensinpris, vagnkilometer och bilinnehav finnes vara -0.4, 0.34, 0.55, and -1.37. Efter att ha tagit hänsyn till att inkomsten påverkar kollektivtrafikresandet direkt såväl som indirekt via bilinnehavet, konstateras att totaleffekten är nära noll.

    I avhandlingens fjärde artikel studeras kollektivtrafikresandet i Linköping. Mellan 1946 och 1983 ökade antalet resor per innevånare kraftigt för att därefter minska. Under perioden 1983 till 2006 minskade antalet resor per person med 71 %. Förutom pris, vagnkilometer och bilinnehav kan det konstateras att kvinnlig förvärvsfrekvens och andel av innevånarna som bor utanför stadskärnan utgör viktiga förklaringsvariabler till resandet. Under expansionsperioden, 1946 – 1983, ökade kvinnors deltagande på arbetsmarknaden kraftigt samtidigt som det skedde en snabb uppbyggnad av förorter med hög befolkningstäthet. Sedan 1983 har kvinnlig förvärvsfrekvens upphört att öka och de befolkningstäta områdena i stadens ytterkanter inte längre växer i förhållande till de centrala delarna. Utan dessa positiva faktorer har utvecklingen dominerats av de negativa influenserna från ökat bilinnehav, ökade biljettpriser och minskat trafikutbud. Effekterna av ett åtgärdspaket bestående av differentierad (mellan hög- och lågtrafik) prissättning, uträtade busslinjer, minskad busstorlek och utspridd skolstart utreds. Slutsatsen är att åtgärderna skulle resultera i 42 % högre kollektivtrafikresande.

    Abstract [en]

    In this article the post war development of public transport demand in the town of Linköping is explained using time series analysis. It is found that the dramatic increase in public transport demand between 1946 and 1983, at least in part, can be explained by the rapid increase in female labour force participation and the expansion of the city’s outer areas. After that, female labour force participation decreased slightly and the town expansion has stopped. Without these positive forces to counterbalance the rising levels of car ownership public transport demand has fallen by 71%. The effects of a policy change, including peak-load pricing, straighter bus routes, smaller bus size and staggered school hours, is analysed. It is found that the proposed package would increase public transport travel by 42 % compared to present policy.

The results are used to provide a ranking (in terms of efficiency) of the Swedish public transport authorities that can provide a basis for benchmarking. It is concluded that the efficiency of the public transport providers in all counties fell during the observed time period. Defining cost efficiency as the ratio of minimum cost to observed cost, the overall (average) cost efficiency for the industry fell from 85.7% in the eighties to 60.4% for the period from 2000 to 2009. Possible explanations for the development include increased emphasis on route density as well as higher environmental and safety requirements.

    The continuing requirements for better urban transport systems in general and the need for a healthier environment haves led to an increased level of research around the world. This is reflected in the proceedings of this well-established meeting which demonstrates the steady growth of research into urban transport systems. The variety of topics covered by the conference is of primary importance for analysing the complex interactions of the urban transport environment and for establishing action strategies for transport and traffic problems.The topics covered in this book include: Environmental impact; Environmentally friendly transport modes; Public transport systems; Transport modelling and simulation; Urban transport management; Transport safety and security; Infrastructure; Land use and transport integration.

    Urban structure as determinant of short distance goods transport2012Ingår i: Procedia - Social and Behavioral Sciences, ISSN 1877-0428, E-ISSN 1877-0428, Vol. 39, s. 582-591Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In this study, data on short distance goods transports is analysed in order to determine if variations in the amounts of goods generated could be explained by geographical and demographical variables. The main purpose is to see if the urbanization and concentration of economic activities has resulted in higher efficiency in the production process, thereby severing the link between increased economic activity and increased transport volumes. The study uses yearly data on freight transport made by truck in 21 Swedish counties between 2000 and 2009, making the number of observations 210. The final model estimated show that after taking geographical and demographical factors into account there is a negative relationship between economic activity and volume of goods transported. This indicates that it is possible to achieve economic growth without necessarily having to accept higher levels of goods transported locally.

    Reducing dependency on special transport services through public transport2017Ingår i: Transportation Research Procedia, ISSN 2324-9935, E-ISSN 2352-1465, Vol. 25, s. 2454-2464Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    One of the official transport policy objectives in Sweden is that all citizens should have access to the transport system. The public sector is therefore required by law to provide special transport services (STS) for those who are unable to use public transport or private car. STS is often provided through public procurement of taxi services. As a response to new legislation in 2000, there have been developments in the public transport sector, making buses, trains and other parts of the system more accessible to people with disabilities. These developments have also been driven by other objectives, such as reducing costs in STS by transferring passengers from STS to regular public transport. However, so far, there is little evidence of the effects of public transport access on STS usage.

    The purpose of this paper is to study the effects of public transport system design on the demand for STS permits and usage. The main focus is on how different aspects of the general public transport system (e.g. price and supply levels) affect the demand for STS permits and STS usage per permit. In addition, the analysis will control for socioeconomic and geographical variables. It is concluded that the price and supply level of public transport do affect STS travel. Public transport price affects the demand for permits as well as the demand for trips from permit holders. Public transport service level only has an effect on the demand for permits.

    Making headway towards a better understanding of service frequency valuations: a study of how the relative valuation of train service frequency and in-vehicle time vary with traveller characteristics2014Ingår i: International Journal of Transport Economics, ISSN 0303-5247, E-ISSN 1724-2185, Vol. 41, nr 1, s. 109-129Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    On-going urbanization has led to greater distances between homes and workplaces and more long-distance commuting, increasing the need for efficient inter-urban transport infrastructure. For sustainability, trains are preferred to private cars.

    Two key variables affecting door-to-door train travel time are in-vehicle time (IVT) and headway ; however, there is often a trade-off between speed and frequency in a system. If different categories of travellers value IVT and headway differently, their proportions on a route should affect traffic planning. Optimal system design might differ between routes carrying many commuters and routes carrying mainly passengers on single private or business trips. Knowledge of differences in relative valuations of headway versus IVT should therefore affect railway system design.

    We investigate whether the relative values of headway versus IVT differ between inter- urban commuting by train and single inter-urban trips by train, whilst also examining differences between socioeconomic groups. Stated choice (SC) data from 580 Swedish respondents are used in estimation. Individuals actually commuting and individuals not commuting but imagining that they are when answering the SC questions are asked about their preferences for headway versus IVT.

    Commuters are estimated to value increased headway 19 percentage points more than do non-commuters. Young people (under age 21 years) value headway more than do older people while people with children value headway less than do the childless.

    Public transport in towns: Inevitably on the decline?2008Ingår i: Research in Transportation Economics, ISSN 0739-8859, E-ISSN 1875-7979, Vol. 23, nr 1, s. 65-74Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In this article the post war development of public transport demand in the town of Linköping is explained using time series analysis. It is found that the dramatic increase in public transport demand between 1946 and 1983, at least in part, can be explained by the rapid increase in female labour force participation and the expansion of the city’s outer areas. After that, female labour force participation decreased slightly and the town expansion has stopped. Without these positive forces to counterbalance the rising levels of car ownership public transport demand has fallen by 71%. The effects of a policy change, including peak-load pricing, straighter bus routes, smaller bus size and staggered school hours, is analysed. It is found that the proposed package would increase public transport travel by 42 % compared to present policy.

    The influence of organisational changes on cost efficiency in fire and rescue services2016Ingår i: International Journal of Emergency Management, ISSN 1471-4825, E-ISSN 1741-5071, Vol. 12, nr 4, s. 343-365Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Fire and rescue services (FRS) in Sweden have recently undergone organisational changes aiming at improving service quality and efficiency. Among those changes are an increased number of formalised cooperations between FRSs, increased collaboration with other sectors, changes in the structure of rescue teams, and an increase in the tasks performed by the services. The purpose of this study was to evaluate whether these policy changes have resulted in increased cost efficiency in the Swedish FRS. We used stochastic frontier analysis of annual data from Swedish municipalities, taking into account contextual differences. No evidence of improved efficiency in the FRS could be found. The policy changes implemented have not had the desired effects, and most of the policy variables tested for inclusion in the model were not significant. The results also show great variation in efficiency between FRSs which could be used for benchmarking and basis for further analysis.

    Pricing public transport services2015Ingår i: Handbook of research methods and applications in transport economics and policy / [ed] Chris Nash, Northampton, MA: Edward Elgar Publishing, 2015, s. 260-308Kapitel i bok, del av antologi (Refereegranskat)
    Abstract [en]

    This chapter aims at outlining pricing policy for public transport that maximizes the social surplus, that is, the sum of the producer surplus and the consumer surplus, while internalizing possible system-external costs. It starts by presenting the door-to-door transport cost as a key concept in price theory for public transport, and then first principles of optimal pricing valid for all modes of public transport are laid down. These principles are applied to urban (short-distance) public transport in sections 13.2–13.5 and to inter-urban (long-distance) public transport in section 13.6. Section 13.7 summarizes the methodological conclusions.

    Kollektivtrafik som verktyg för regional utveckling: En kunskapsöversikt2012Rapport (Övrigt vetenskapligt)
    Abstract [sv]

    Syftet med rapporten är att förbättra kunskaps- och beslutsunderlag för en effektivare användning avkollektivtrafiken som utvecklingsverktyg. Uppdraget baseras på kollektivtrafikrelaterad ekonomiskforskning med fokus på lokal och regional utveckling. Kunskapsöversikten utgår i första hand frånforskning om kollektivtrafikens samhällsekonomi och planeringsmässiga dimensioner.

     

    Forskningsresultaten har valts ut med utgångpunkt från det ökade behovet av kunskapsunderlag och planeringsmodeller för integrerade regionala och lokala kollektivtrafiksystem. Vi har tolkat uppdraget utifrån de framväxande regionernas behov av tydligare strategier för hur kollektivtrafiken kan användas som verktyg för regional utveckling. Kollektivtrafiken kan kopplas till drivkrafter för den ekonomiska utvecklingen vad gäller transportmöjligheter, mobilitet och tillgänglighet generellt, men också mer direkt till de egenskaper som kollektivtrafiken har i jämförelse med övriga färdmedel. Kollektivtrafiken har hög kapacitet och ett begränsat ytanspråk vilket gör att den kan användas för att åstadkomma kluster med agglomerationsfördelar och för att realisera skalekonomier och gynnsamma produktionsförutsättningar för den växande tjänstesektorn. Det är vår uppfattning att det behövs en betydligt starkare strategisk dimension i planeringen av kollektivtrafiken. Det avgörande är inriktningen för trafiken och hur kollektivtrafiken ska användas som verktyg för regionens utveckling. I planeringen kan flera olika förändringar/ kvalitetsnivåer utvärderas och perspektivet måste vara bredare än att enbart fokusera på investeringar. Av diskussionen i rapporten följer att den rumsliga dimensionen blir alltmer betydelsefull för den ekonomiska utvecklingen. Konsekvenser för stads- och tätortsutveckling, regionala sammanhang och hur markanvändning och transportsystem samverkar bör lyftas in i planeringens centrum. Oavsett nivån i resurstilldelningen till kollektivtrafiken är det angeläget att de resurser som förbrukas gör största möjliga nytta. Om det är positiva konsekvenser för en hållbar ekonomisk utveckling som prioriteras, bör planeringen ställas om i den riktning som diskuteras i rapporten.

    The Influence of Organizational Changes on Cost Efficiency in Fire and Rescue ServicesManuskript (preprint) (Övrigt vetenskapligt)
    Abstract [en]

    Fire and rescue services in Sweden have recently undergone organizational changes aiming at improving service quality and efficiency. Among those changes are an increased number of formalized cooperations between FRSs in neighboring municipalities, increased collaboration with other sectors in day-to-day operations, changes in the structure of rescue teams, and an increase in the tasks performed by the services. The purpose of this study was to evaluate whether these policy changes have resulted in increased cost efficiency in the Swedish FRS. We used stochastic frontier analysis of annual data from 2009 to 2012 for 205 Swedish municipalities, taking into account the relevant differences in conditions among them. The conclusion is that there is no evidence to be found of improved efficiency in the FRS. The policy changes that have been implemented have not had the desired effects, and most of the policy variables tested for inclusion in the model were not found significant. Recommendations for future research are to further investigate why these policy changes have not yet given the expected results, to examine how and if collaboration with different types of organizations (public, private and non-profit) affects efficiency differently and to make further in-depth comparisons between the most efficient and least efficient FRSs for there are great variations between them.
