Consumer Attitudes and Their Forecasting Power for Consumer Spending

The University of Michigan's Surveys of Consumers is summarized with principal components of consumer attitudes with respect to income and wealth, prices, and interest rates and credit availability. These summary measures contain information beyond that captured by the Index of Consumer Sentiment. The summary measures have forecasting power for aggregate consumption behavior, even when controlling for economic fundamentals. These measures also help to improve significantly upon Survey of Professional Forecasters, Blue Chip Consensus, and Federal Reserve Board's forecasts of consumption and other real activity measures, consistent with their predictive ability conditioned upon a broader set of fundamentals and forecasters’ judgment.     

Examining the prospects for Gigabit Broadband: Lessons learned from Google Fiber

This study examines possible lessons learned from the deployment of residential Gigabit networks based upon the novel approach taken by the Google Fiber project started in 2010. Even though Google Fiber paused any project expansion in 2016, calling into question the viability of their business model, the approach taken by Google Fiber elicits further research interest given four major innovations that this analysis identifies in its fiber-to-the-home business model. Based on a “top-down” financial model to estimate the costs of fiber deployment, this analysis shows that these four innovations pursued by Google Fiber, and now adopted on a widespread basis by other broadband providers, lower the costs of building residential Gigabit networks, and therefore can improve the prospects for new entry of service providers of residential broadband services. With technology advances pointing to further cost reductions in the cost of Gigabit networks, this analysis elevates the need for more detailed study of ongoing changes in the cost structure of local access networks to better anticipate future prospects for broadband competition.

玄武岩纤维混凝土力学性能试验研究

为提高混凝土的抗弯拉性、抗冲击性和耐磨性,在混凝土中添加玄武岩纤维,制成玄武岩纤维混凝土。对不同水灰比、不同玄武岩纤维含量的10种常用配合比混凝土,开展了水泥混凝土立方体抗压强度试验、抗弯拉强度试验、断裂能试验和耐磨性试验,研究了玄武岩纤维含量对混凝土抗压强度、抗弯强度、断裂能和耐磨性的影响。结果表明:添加2~4kg/m3的玄武岩纤维,混凝土的抗弯强度增加4%~13%,断裂能增加23%~138%,磨耗值降低2%~18%,混凝土抗压强度下降4%~18%。
