Using a structural model of demand for automobile engine variants, this paper finds that there is second-degree price discrimination: markups increase with engine size. Still, average markups are lower than when models have just one engine. The paper develops the first empirical demand framework suitable for markets with variants. There is an unobserved product characteristic and a consumer-spe...

background: occupational and environmental exposures mostly represent mixtures of genotoxic agents, whereas the specificity of biomarker measurements varies widely. exploration of correlations among biomarkers contributes to the further progress of molecular cancer epidemiology and to the selection of the optimal biomarkers for the investigation of human exposure to carcinogens. the aim of this...

OBJECTIVE Details on airbag injuries to the upper extremity are relatively unknown to clinicians. The injuries presented here should provide a clear understanding of the mechanisms of forearm, hand, and wrist injuries that may be seen by emergency room physicians. MATERIALS AND METHODS From our crash investigations of 325 airbag-equipped passenger cars, a subset of upper extremity injuries ar...

As resource scarcity and environmental degradation has aroused global concern, new energy vehicles have become the developing trend of automobile industry all over the world. However, there is lack of incentive for innovations on more environmentally friendly automobile technology. This paper introduces endogenous and directed technology progress into the growth model to analyze the decision-ma...

In order to safeguard the future of Chinese automobile industry, and maintain and strengthen its acceptance in Chinese community, it should be made a commitment to sustainability. The approaches to sustainability in Chinese automobile industry should comprise three aspects: nature conservation, production-related environmental protection and “5R” implementation which is considered as sustainabl...

The automobile Real-Time Operating System (RTOS) is hard to design and implement due to its real time features and increasing complexity. Some automobile RTOS standards are released aiming at unifying the software architecture of vehicle systems. Most of the standards are presented informally in natural languages, which may lead to not only ambiguities in specifications but also difficulties in...
