We investigate the hypothesis that zero lower bound monetary policy has an effect on the correlations of financial assets. Using an event-study approach, we evaluate the impact of the zero lower bound monetary policies of the Bank of Japan, the Bank of England, and the Federal Reserve on the bond and equity markets in Japan, the UK, the US, and the Eurozone. We evaluate the bond markets using the Japanese 10-year Sovereign bond (JGB), UK 10-year bond (Gilt), US 10-year Treasury note (T-note), and German 10-year bond (Bund). For the equity markets we use the Nikkei 225, FTSE 100, S&P 500, and Euro STOXX 600 as proxies for each regional market. We also include gold and silver as control commodities. Our analyses demonstrate significant changes not only in the evaluated assets’ correlations with each other, but also in their general behavior. This has major implications for investment portfolio construction and provides useful insight for financial service regulators and the central banks themselves in monitoring the fragility and stability of the financial system.  相似文献

Cooperative Research and Development Agreements (CRADAs) between Federal R&D laboratories and private companies in the US are intended, in large part, to transfer technologies developed at Federal R&D laboratories to private companies. We surveyed the Federal laboratory and private CRADA partners involved in CRADAs at Los Alamos National Laboratory in New Mexico in order to identify certain difficulties inherent in CRADAs as mechanisms for technology transfer. Company partners do not share a common organizational culture with their Federal laboratory counterparts, and are critical of the length of time and complexity of government administrative arrangements necessary to form a CRADA.  相似文献

Power in K–12 education is rapidly moving from local school boards and government to extraordinarily wealthy private philanthropists. Building networks among nonprofits, government agencies, school districts, and others, private foundations such as the Gates, Broad, and Walton family foundations are fundamentally restructuring American K–12 education. The Common Core State Standards, teacher evaluation, and charter schools are a few of the initiatives these funders are backing. The massive influx of private money into education policy and its influence over public education raises questions around the proper role of philanthropy in a democracy. In a society with increasing wealth inequality, should the economic elite be able to gain further power to shape social institutions through giving? Are there or should there be any limits to this power? Examining specific trends and events in education philanthropy over the last 10 years, this article identifies key players in philanthropic education reform and argues that philanthropy in education is now playing a policy‐making role—without checks and balances—that is qualitatively and quantitatively different than before. I conclude with a cautionary note on the dangers of letting education policy become the domain of the economic elite.  相似文献

This paper examines the relationship between a Real Estate Investment Trust's (REIT's) stock returns and top management changes. The results indicate an inverse relationship between the probability of a management change and a REIT's recent stock price performance. This is consistent with internal monitoring of management activities by the board of directors, other top managers, or large block shareholders.  相似文献

The paper presents the first analysis of insider trading in the context of public policy implementation. The Securities and Exchange Commission (SEC) proscribes trading by corporate insiders upon material information that is not yet in the public domain. Although the SEC interprets what constitutes material information, it has historically focused on earnings, mergers, and acquisitions. Using a panel of US firms from 1985–87, the authors disclose a significant relationship between the filing of an antidumping petition and insider buying in the two months preceding the filing month. This suggests that the SEC should expand its focus to include public policy.  相似文献

The author examines characteristics of the nonmetropolitan elderly in the United States. "A larger share of the nonmetro population was age 60 and older (18 percent) in 1996 than the metro population (15 percent). At ages 75 and older, half of all elderly persons are living alone. This is associated with a greater likelihood of being poor: 42 percent of nonmetro persons age 75 and older were poor or near-poor, compared with 28 percent of their metro counterparts."  相似文献

Efficient frontier estimation: a maximum entropy approach   总被引:1,自引:0,他引:1  
An alternative efficiency estimation approach is developed utilizing generalized maximum entropy (GME). GME combines the strengths of both SFA and DEA, allowing for the estimation of a frontier that is stochastic, without making an ad hoc assumption about the distribution of the efficiency component. GME results approach SFA results as the one-sided inefficiency bounds used by GME shrink. Results similar to DEA are achieved as the bounds increase. The GME results are distributed like DEA, but yield virtually the same rankings as SFA. The results suggest that GME may provide a link between various estimators of efficiency.
