Do satisfying walking and cycling trips result in more future trips with active travel modes? An exploratory study

Previous studies have indicated that travel satisfaction - the experienced emotions during, and cognitive evaluation of, a trip - can be affected by travel mode choice and other trip characteristics. However, as satisfactory trips might improve a person's attitude towards the used mode, persons may be more likely to use that same mode for future trips of the same kind. Hence, a cyclical process between travel mode choice and travel satisfaction might occur. In this paper we begin to analyse this process—using a structural equation modelling approach on cross-sectional data—for people who engage in walking and cycling for leisure trips in the Belgian city of Ghent. The focus on walking and cycling reflects recent studies indicating that active travel is often associated with the highest levels of travel satisfaction. Results of this exploratory analysis offer tentative support for the idea of a cyclical process: the evaluation of walking and cycling trips positively affects the respondents' attitude towards the respective mode, which in turn has a positive effect on choosing that mode.     

Improving the Health of Healthcare Companies

The healthcare sector has been extremely effective in improving human health while at the same time delivering outstanding returns to shareholders, at least on average. But averages can hide a lot of poor performance, and careful examination of the sector shows a sizable disparity between the long‐run productivity and value added of the top companies and the rest. To better understand the reasons for this disparity, the authors undertook a comprehensive study of how differences in capital deployment strategies, financial policies, and measures of corporate operating performance such as sales growth and return on capital are associated with returns to shareholders. Perhaps the most striking finding is the strong positive correlation in the healthcare industry between higher rates of reinvestment, especially in the form of spending on R&D and acquisitions, and stock price performance. And given the importance of such reinvestment, it is not surprising that maintaining financial flexibility by paying down net debt and otherwise limiting corporate leverage—and even issuing significant equity—are all associated with higher stock returns. When it comes to operating performance, moreover, it's not enough just to be good; it takes growth and improvement in cash flow and earnings to drive share prices higher. Measures of changes in performance such as increases in EBIT and ROIC, and high rates of growth in sales, all show consistently strong and positive relationships with stock returns while measures of levels of performance, especially EBIT margins and EBITDA margins, demonstrate relationships that are weak and in some cases even negative. Last, and consistent with the findings reported above, despite often vocal investor demands to pay dividends and buy back shares, in the case of healthcare as a whole such distributions have a clearly inverse relationship with share price performance. That is to say, the larger the payouts to shareholders, the lower the shareholder returns.     

Car ownership as a mediating variable in car travel behaviour research using a structural equation modelling approach to identify its dual relationship

Car ownership is generally considered an important variable in car travel behaviour research, but its specific role is often not well understood. Certain empirical studies consider car ownership as the dependent variable explained by the built environment, whereas other studies deem it to be one of the independent variables explaining car travel behaviour. This paper takes note of the dual influence car ownership has in explaining car travel behaviour by assuming that car ownership mediates the relationship between the built environment and car use. The relationship is estimated using a structural equation model since it accounts for mediating variables. This approach confirms the intermediary nature of car ownership.     

Measuring Employment Security in Europe Using Surveys of Employers

Using results from surveys in which employers were questioned about their freedom to shed staff, we develop a measure of employment security in Europe. We seek to identify which institutional factors are correlated with the responses of employers and find that they appear to reflect the strength of legal restrictions and trade unions and the prevalence of atypical employment. Our results are used to compile an index of employment security that has both a temporal and a cross‐country dimension.     

Institutional Environment and Technical Efficiency: A Stochastic Frontier Analysis of Cotton Producers in West Africa

This paper examines the effects of the institutional environment on West African cotton farmers’ technical efficiency (TE). First, key aspects of the cotton sector institutional environment are discussed, including input and credit access, and producers’ organisations. Then, a stochastic frontier production function, which incorporates technical inefficiency effects, is applied to farm level data collected in Benin, Burkina Faso and Mali. The survey includes farmers’ evaluations of the cotton sector institutional environment. Results suggest that institutional level features influence producers’ TE, besides farm‐level characteristics. Cotton growers who report a negative experience with the joint liability programme, who identify the cotton price mechanism or access to credit as the main constraints to performance, and who cultivate more hectares of cereals are technically more inefficient in producing cotton. Findings suggest that cotton farmers in Mali are less technically efficient in producing cotton than in Burkina Faso and Benin. Agricultural development policies focusing on reducing farmers’ financial stress, particularly through the establishment of adequate price mechanisms (i.e. higher farm‐gate prices and timely payments to farmers) and improvement in the input–credit markets should be encouraged to improve TE in West Africa.     

Prices,institutions, and determinants of supply in the Malian cotton sector

Cotton, both a source of livelihood for millions of poor rural households and a major source of export revenues, is a vital commodity for the economic and social development of Mali. Inefficiencies in the Malian cotton system at the ginnery and producers’ cooperative levels (e.g., late payment to farmers and poorly functioning credit schemes) have recently led to an important decline in supply, threatening the sustainability of the sector. Using regional data from 1998/1999 to 2008/2009, this study aims to quantitatively assess the contribution of key determinants, such as cotton prices and timely payment, toward the downward trend in cotton area. A dynamic supply model, based on adaptive expectations and partial adjustment, is employed to estimate the effects of prices and institutional factors, such as credit recovery rates and date of payment to farmers, on the Malian cotton supply. Results show that supply responds significantly to cotton prices relative to cereal and fertilizer prices. Date of payment varies across agricultural cycles and late payment negatively influences land devoted to cotton. Low credit repayment rates create disincentives to grow cotton. Therefore, the revitalization of the Malian cotton sector depends upon getting both prices and institutions right.     

Key research themes on travel behavior,lifestyle, and sustainable urban mobility

abstract

The concept of lifestyle adds a behavioral component to travel models that used to be dominated by engineering and econometric traditions. This article presents an overview of how lifestyle is defined and measured in transport studies, and how travel behavior is influenced by lifestyles. Lifestyles are often used pragmatically rather than theoretically in the behavior studies. Nevertheless, some important theoretical contributions have been made, especially in sociology by scholars such as Weber, Bourdieu, Ganzeboom, and Schulze who agree on the communicative character of lifestyles: individuals express their social position through specific patterns of behavior, consumption, and leisure. These behavioral patterns are shaped by underlying opinions and orientations, including beliefs, interests, and attitudes. Thus, travel behavior is not simply determined by price, speed, and comfort but is also related to attitudes, status, and preferences. Because lifestyle has many different dimensions, a variety of measurement approaches exists. Nevertheless, most studies suggest that travel behavior is conditioned by specific lifestyles. How lifestyles themselves can be modified to promote more sustainable patterns of transport has not received much attention to date. This article argues that lifestyles need to be considered as dynamic rather than as static and given, and that future research could delve more deeply into this area.     

The Evolution and Nature of Young Firm Networks: a longitudinal Perspective

This paper describes the evolution of networks during the first three years after start-up and puts forward explanations of the nature of networks of young firms after three years. We extend current research on networks by explicitly including both temporal change and spatial variation in our analyses of the longitudinal dataset. In this paper we define networks as: the main business relationships with respect to sales, supply, outsourcing and cooperation. The nature of these business relationships is specified by four main characteristics: type, number, source, and location. The longitudinal network analysis is therefore at the micro-level: the individual young firm and the characteristics of its most important business contacts are central. In contrast to the literature our analyses show that sales relationships become increasingly social in source during the first three years after start-up. We also find a persistent geographical concentration strategy in the main business relationships. It seems that extra-regional relationships are losing ground to intra-regional relationships over time: firms are narrowing their spatial scope in their first three years. In addition, we trace important effects of gender, education, innovative firm behaviour, region and sector on the nature of young firm networks three years after start-up.     

Environmental motivations behind individuals’ energy efficiency investments and daily energy-saving behaviour: evidence from Germany,the Netherlands and Belgium

The impact of environmental motivations on the individual’s decisions regarding investments in energy efficiency and the adoption of energy-saving habits are analysed on the basis of a representative online survey carried out in Belgium, Germany and the Netherlands. Various energy efficiency investments and daily energy-saving activities are considered. Accounting for endogeneity in the basic estimation model, in particular regarding energy conservation activities, the subject’s experience with extreme weather events are used as an instrument for environmental motivations. This study provides empirical evidence that individual energy efficiency investments are generally driven by environmental motivations. Additionally, for the Dutch and the German sub-samples environmental motivations positively affect daily energy-saving activities. The findings suggest that policy programmes aimed at raising environmental awareness and forming pro-environmental motivations can lead to an increase in energy efficiency investments and daily energy-saving activities.     

Creative destruction and regional productivity growth: evidence from the Dutch manufacturing and services industries

Do firm entry and exit improve the competitiveness of regions? If so, is this a universal mechanism or is it contingent on the type of industry or region in which creative destruction takes place? This paper analyses the effect of firm entry and exit on the competitiveness of regions, as measured by total factor productivity (TFP) growth. Based on a study across 40 regions in the Netherlands over the period 1988–2002, we find that firm entry is related to productivity growth in services, but not in manufacturing. The positive impact found in services does not necessarily imply that new firms are more efficient than incumbent firms; high degrees of creative destruction may also improve the efficiency of incumbent firms. We also find that the impact of firm dynamics on regional productivity in services is higher in regions exhibiting diverse but related economic activities.
