This study examines how the Fed's monetary policy decisions affect the implied volatility of the S&P 500 index. The results show that stock market uncertainty is significantly affected by the Fed's policy decisions. In particular, we find that implied volatility generally decreases after FOMC meetings, while the relationship between target rate surprises and market uncertainty appears positive. However, our results also suggest that the apparent positive relationship between policy surprises and implied volatility is mostly driven by the volatility‐reducing effects of negative surprises. We further document that implied volatility is affected by both scheduled and unscheduled policy actions, with the scheduled path surprises having the strongest impact on volatility. Finally, our findings indicate that the impact of monetary policy decisions on implied volatility is more pronounced during periods of expansive policy. © 2010 Wiley Periodicals, Inc.

The adoption of new practices by farmers is one of the key strategies to lower greenhouse gas (GHG) emissions from food production. In this context, effective knowledge transfer systems are essential to inform farmers about climate change, and to convince them of the benefits of new technologies. In this article, farmers’ opinions about climate change, their own efforts to mitigate climate change, and their suggestions on how to improve agricultural advice were assessed. To this end, a survey with over 500 livestock farmers was conducted in Ireland. The findings reveal a high awareness of the urgency to address climate change in general, but many farmers also think agricultural GHG emissions are an overstated problem. In addition, half of the surveyed farmers believe that implementing GHG mitigation measures will lower their profits. These findings underline the need to provide effective knowledge transfer to facilitate the uptake of GHG mitigation measures. When asking farmers directly, by way of text analysis, it emerges that simple messages, group and practical advice that is tailored to individual farming situations is important to farmers. As such, this article provides important insights that are of relevance for designing advisory campaigns to promote climate change mitigation. 相似文献

Although structural change in many industrialized countries has increased since the early 1970s, the environmental policy aspects of this change have hardly been investigated. Using a set of four indicators, this study examines the correlation between structural changes and environmental pollution in thirty-one Eastern and Western industrialized countries from 1970 to 1985. 相似文献

The forecasting of basic technological innovations is focused. Clarification of the involved key concepts and an analytical framework are given. The forest industry serves as a background and illustration to the discussion. Considerable uncertainty prevails with respect to strategic investments in production in this industry. Industries, technological products, etc. have empirically been shown to pass similar phases of development over time. This life cycle starts with a basic innovation following on a previous invention. Due to competetion from more recent basic innovations the final phase is one of decline. Basic innovations are suggested to be exogenously determined and to cause structural change. The choice of forecasting strategy is suggested to be made dependent on the type of innovation, knowledge base, and life cycle position. 相似文献

Using some general properties of ensembles of systems the size distribution of scarce resources in society is derived.Using Keynsian distribution theory and the Life-Cycle Hypothesis of saving the size distribution of income in society is determined.Specifically the distributive shares going to labor and capital are derived.It is shown that the results are consistent with empirical data. 相似文献
