A comment on gasoline prices and urban structure

The effect of higher gasoline prices on urban concentration and aggregate work travel is investigated with a simple closed-city general equilibrium model used by Robson and Scheffman. Their approximate solution is shown to be invalid at reasonable parameter values; for the case of a Cobb-Douglas utility function, numerical solution indicates a long-run reduction in average trip length of 1.4% to 2.9% from an increase in transportation cost of 0.5 cents per mile. It is noted that this is still much larger than estimates obtained by other means.     

R&D Performance of UK Companies

This short article compares the R&D performance of the major British R&D spenders with that of other major R&D spenders world-wide. A performance index is constructed which adjusts actual R&D for firm size and the R&D intensity of the firm's main area of business. According to these performance measures, the R&D performance of these British firms is better than is suggested by the share of R&D in Britain's GDP. However, the article identifies a gap in British R&D performance - what may be called a third rank of R&D spenders - who are rare in Britain, but very common in Japan and the USA.     

A quantitative exploration of the opportunistic approach to disinflation

Under a conventional policy rule, a central bank adjusts its policy rate linearly according to the gap between inflation and its target, and the gap between output and its potential. Under “the opportunistic approach to disinflation” a central bank controls inflation aggressively when inflation is far from its target, but concentrates more on output stabilization when inflation is close to its target, allowing supply shocks and unforeseen fluctuations in aggregate demand to move inflation within a certain band. We use stochastic simulations of a small-scale rational expectations model to contrast the behavior of output and inflation under opportunistic and linear rules.     

Socio-Political Evaluation of Energy Deployment (SPEED): An integrated research framework analyzing energy technology deployment

Stabilizing atmospheric concentrations of greenhouse gases to reduce the risks of climate change requires a major transition in society's energy infrastructure; yet despite a growing sense of urgency, deployment of alternative emerging energy technologies has been slow and uncertain. This paper proposes a systematic, interdisciplinary framework for the integrated analysis of regulatory, legal, political, economic, and social factors that influence energy technology deployment decisions at the state level to enhance awareness of the interconnections and enable improved energy policy and planning and accelerated change in society's energy infrastructure. This framework, Socio-Political Evaluation of Energy Deployment, (SPEED), integrates analysis of laws, regulations, institutions and policy actors as well as varying regional perceptions and levels of awareness about the risks and benefits of emerging energy technologies to facilitate improved understanding of the complex interconnected components of state energy systems. While this framework has been developed with U.S. states as a model, the SPEED framework is generalizable to other countries with different sub-national structures. We present three research methods that could be applied within the SPEED framework that could be particularly helpful in understanding the integrated socio-political influences on energy technology deployment: (1) policy review and analysis, (2) media analysis, and (3) focus groups and structured interviews with key stakeholders. By integrating the fields of technology diffusion, environmental policy, comparative analysis of states, and risk perception, future empirical research conducted within this SPEED framework will improve understanding of the interconnected socio-political influences on energy technology deployment to enable energy modelers, policy-makers, energy professionals, state planners and other stakeholders to develop and implement more effective strategies to accelerate the deployment of emerging energy technologies.     

What information belongs in a warning?

A general approach is described for determining the information content of warnings. It begins with a formal analysis of the magnitudes of the risks arising from misuse (or even from proper use) of a product. It proceeds with structured, open-ended interviews intended to elicit consumers' naive conceptualizations of the processes creating and controlling those risks. Communications are then focused on information filling the most consequential gaps in their knowledge. The implementation of those warnings will depend on the extent of the knowledge gaps, and the opportunities for closing them. This approach allows for an estimate of the residual problems to be expected, if a warning program is implemented. It can also help to focus the policy debate over whether a product warning will achieve an acceptable level of misunderstanding. © 1998 John Wiley & Sons, Inc.     

Economics and urban transportation policy in the United States

This article examines the role that economics can play in analysing problems with urban transportation in the United States. The specific problems addressed are failing infrastructure, financially weak public transit, environmental impacts of motor vehicles, motorvehicle accidents, and traffic congestion. Simple quantitative analyses, even though approximate, can help to focus attention on the most promising classes of policies. Those classes involve some technological measures and some narrowly targeted behavioral changes, but not the widespread curtailment of motor vehicle use.     

The influence of internal and external social networks on HRM capabilities in MNC subsidiaries in China

In this study we examine the influence of involvement in internal and external social networks on HRM capabilities. We distinguish between technical and strategic HRM capabilities and focus on the capabilities of the HR department relating to four HRM practices – recruitment and selection, training and development, compensation, and performance appraisal. The study is based on data from dual respondents, general managers and HR managers, in 66 European MNC subsidiaries located in China. The results indicate that contact with other MNCs in China regarding HRM issues is positively associated with both technical and strategic HRM capabilities whereas contact with local Chinese companies does not have any significant influence on either strategic or technical HRM capabilities. Contact with MNC headquarters is positively associated with strategic HRM capabilities.     

ENDOGENOUS SCHEDULING PREFERENCES AND CONGESTION

We consider the timing of activities through a dynamic model of commuting with congestion, in which workers care solely about leisure and consumption. Implicit preferences for the timing of the commute form endogenously due to temporal agglomeration economies. Equilibrium exists uniquely and is indistinguishable from that of a generalized version of the classical Vickrey bottleneck model, based on exogenous trip‐timing preferences, but optimal policies differ: the Vickrey model will misstate the benefits of a capacity increase, it will underpredict the benefits of congestion pricing, and pricing may make people better off even without considering the use of revenues.
