An effective diffusion model characterized by the technology-induced function diversification and cost reductions can be developed to reflect whether competition exists among multiple generations of technology and to interpret how price reductions stimulate consumption. New technology can enhance the production skill levels of LCD TV manufacturing, enabling successive generation of LCD TV to become larger-sized than the previous generation, reducing the overall cost in manufacturing process and resulting in the price reduction of LCD TVs. However, previous diffusive predictions of LCD TVs using conventional multi-generational models ignore the price effect on market potentials and generational substitutions, so a novel generation-specific multi-generational model for the first time incorporating heterogeneous price elasticity and consumer behaviors across various LCD TV sizes is constructed in this work. This study applies nonlinear least square method to simulate the parameters of our modified model and further compares the accuracy between our modified model and the existing models. Analytical results indicate that price reduction strongly correlates with LCD TV sales, implying that price reductions increase the market potential of each LCD TV generation. Our modified model performs superior to the conventional multi-generational model in terms of predicting future shipment orbits of 26-, 42-, and 46-in. LCD TVs. 相似文献

Sustainable investment responds to demands for carbon and climate-neutral societies. To address the urgency around climate change and provide investors with more qualified information, Morningstar has developed the Low Carbon Designation (LCD) to indicate that the companies held in a portfolio are in general alignment with the transition to a low-carbon economy. The designation is given to portfolios that have low carbon risk and fossil fuel exposure scores. The present study builds on the LCD by examining the relationship between these scores and financial performance. With this aim, we analyze 3920 socially responsible mutual funds from across the world. Results show differences in financial performance according to scores and investment areas. We find evidence that funds considered to have higher levels of sustainability achieved better performance than funds with higher exposure to companies involved in carbon and fossil fuel industries. We provide insights on the informativeness of these new scores with a focus on climate change and their relevance in helping investors to identify climate-aware funds. This study highlights the importance of introducing strategies to develop green finance; the analysis confirms that sustainability improves performance. Finally, the LCD indicator is shown to be relevant for making fairer comparisons among socially responsible funds and, ultimately, for developing low-carbon economies. 相似文献
