Evaluation of land-use and transport network effects on cyclists' route choices in the Copenhagen Region in value-of-distance space

Growing interest in sustainable transportation systems has driven decision-makers toward policies and investments aimed at promoting cycling, but little to no effort has been made toward incorporating bicycle transport in transport planning models. This study contributes toward this direction by estimating a bicycle route choice model in value-of-distance space from a large sample of 3384 cycling trips that were traced with GPS devices in the Copenhagen Region. The novelty of this study lies in (i) observing cyclists' behavior in a cycling-oriented country, (ii) exploiting rich data about the cycling environment, (iii) estimating the model in value-of-distance rather than preference space, and (iv) not focusing only on preferences for traditional variables (e.g., distance, turns, hilliness, intersections, motorized road characteristics), but also on perceptions and preferences for bicycle facilities (e.g., bicycle lanes, bicycle paths, bicycle traces) and land-use designations (e.g., residential, industrial, sports, scenic areas). The findings from the model show that: (i) cyclists exhibit heterogeneous preferences for avoiding right and left turns, cycling the wrong way, using roundabouts and bridges, and cycling alongside residential and scenic areas; (ii) cyclists dislike cycling on unpaved and hilly surfaces and alongside larger roads; (iii) cyclists have clear perceptions about different types of bicycle facilities, with a preference for bicycle lanes and segregated paths; (iv) cyclists have clear perceptions about land-use designations, with a preference for cycling alongside sports and scenic areas; (v) time-of-day and air temperature contribute to the perceptions of cyclists and their preferences for bicycle facilities and land-use designations.     

A welfare evaluation of the 1986 tax reform for married couples in the United States

This paper evaluates the welfare effects of the 1986 Tax Reform Act (TRA86). We rely on different welfare metrics, which fully retain preference heterogeneity and are based on different ethical priors. We estimate utility functions with preference heterogeneity on the basis of structural models of family labor supply. Then, using these estimated preferences, we compute and compare different well-being rankings corresponding to different ways of measuring well-being. Finally, we identify the losers and the winners of TRA86, in absolute and relative terms, for each of the welfare metrics.     

THE CREATION AND DIFFUSION OF INNOVATION IN DEVELOPING COUNTRIES: A SYSTEMATIC LITERATURE REVIEW

In this study, we review the literature on the creation and diffusion of innovation in the private sectors (industry and services) in developing countries. In particular, we collect evidence on what are the barriers to innovation creation and diffusion and the channels of innovation diffusion to and within developing countries. We find that innovation in developing countries is about creation or adoption of new ideas and technologies; but the capacity for innovation is embedded in and constituted by dynamics between geographical, socio‐economic, political and legal subsystems. We contextualize the findings from the review in the current theoretical framework of diffusion of innovations, and we emphasize how the institutional context typical of developing countries impacts the diffusion itself.     

Explicit and implicit corporate social responsibility: Differences in the approach to stakeholder engagement activities of U.S. and Japanese companies

This study uses the theoretical frameworks of institutional theory and comparative capitalism to demonstrate how cross‐cultural differences in national institutional frameworks are related to differences in the meaning and the nature of corporate social responsibility (CSR) and, as a result, how they create different incentives and opportunities for companies to engage in stakeholder management activities. More specifically, we draw upon the framework of “explicit” and “implicit” CSRs to investigate whether and how stakeholder management practices and programs differ between the United States and Japan. We first develop and validate a Stakeholder Engagement Activities (SEAs) scale, designed assess differences in the approach (explicit or implicit) that companies use to address a variety of common SEAs. Then we analyze data and present the results of surveys collected from 227 companies in the United States and Japan. We find that although the SEAs of American companies are characterized by strong “explicit CSR,” in contrast, the SEAs of Japanese companies exhibit strong “implicit CSR.” In the discussion that follows, we attribute these distinctions in the SEAs to differences in the configuration of political, economic, and market mechanisms in each country. The findings of this study contribute to a more nuanced understanding of the differences in prevailing CSR practices of American and Japanese companies than noted by previous researchers. From a practitioner's perspective, the findings of this study reveal that despite the global nature of CSR, stakeholder management practices are both interpreted and operationalized differently due to differences in national institutional frameworks.

The Effects of Integrated Pollution Prevention and Control (IPPC) Regulation on Company Management and Competitiveness

In the literature there are several studies about the effects of environmental policies and regulations on the management and competitiveness of businesses. Some of these studies focus on the Integrated Pollution Prevention and Control (IPPC) Directive, but only a few investigate the effects of IPPC permits in depth. This paper aims to bridge this gap by illustrating the results of cross‐country empirical research. We analyse 225 IPPC permits of companies located in seven European regions and issued by different competent authorities. Results show differences in terms of requirements, emission limit values and monitoring frequencies, which are not always justifiable by the flexibility afforded by the Directive. These differences have different impacts on the competitive strategies and environmental management of companies within the same sector but located in different countries. We explore how some differences could influence company costs, contributing to the literature debate about the effects of direct regulation on competitiveness.
