Drawing on the work of Jenkins and Perrow, a content analysis of information in the New York Times Index is examined to analyze the environment of the consumer movement in the United States over a fourteen-year period. The results suggest that a fundamental change has occurred in the movement, with less visible activism and less overt business support being provided.  相似文献

Metropolitan sales data from the 1977 Census of Retail Trade were analysed to test whether phosphate detergent bans increased consumer expenditure on clothing: positive effects were found for men's clothing and domestic fabrics (sheets and towels). In areas with medium water hardness the average annual cost in 1977 equalled $11·08 per household. For 1984, the equivalent cost was $14·17 per household. These results are consistent with laboratory studies that show decreased detergency associated with non-phosphate detergents and increased fabric wear associated with carbonate-built detergents, the principle substitute for phosphate detergents. The bans impose the largest cost on hard water areas. In both ban and non-ban areas in 1977 higher laundering costs were associated with higher water hardness. Analysis of 1972 data indicated that water hardness did not affect clothing expenditures significantly when detergents contained large amounts of phosphates.  相似文献

Over March and April 2000, Internet stocks lost 56%, or $700 billion. This sudden collapse has been attributed to an increasing supply of shares from lockup expirations and equity offerings. I show that Internet stocks collapsed in this period regardless of whether their lockups expired. Furthermore, daily Internet stock portfolio returns were almost unaffected by the number or dollar amount of lockup expirations that day, or by the amount of stock offered in IPOs or SEOs. Most of the Internet stock decline is explained by poor marketwide returns, particularly for growth stocks.  相似文献

Focusing on a set of central banks that publish inflation forecasts in real time, this paper aims to establish whether central bank inflation forecasts influence private inflation forecasts. The response is positive in the five countries studied: Sweden, the United Kingdom, Canada, Switzerland, and Japan. Three hypotheses may explain this central bank influence: central bank forecasts are more accurate than private ones, are based on different information sets, and/or convey signals about future policy decisions and policymakers’ preferences and objectives. We provide evidence that the source of these central banks’ influence is not linked to their forecasting performance.  相似文献

While many studies find that option prices lead stock prices, Stephan and Whaley (1990) find that stocks lead options. We find no evidence that options, even deep out-of-the-money options, lead stocks. After confirming Stephan and Whaley's results, we show their results can be explained as spurious leads induced by infrequent trading of options. We show that the stock lead disappears when the average of the bid and ask prices is used instead of transaction prices. Hence, we find no evidence of arbitrage opportunities associated with the stock lead.  相似文献

From 1984 gas‐fired power generation had been gradually increasing its share of the electricity market in Western Australia (WA) starting at 1 per cent and rising to about 50 per cent by 2008. Had it continued on this trajectory, the WA power system would have made great advances in terms of cost and environmental efficiencies given the looming commencement of the Carbon Pollution Reduction Scheme in Australia from 2011. However, more recently the cost of natural gas has increased from $3/GJ to $7/GJ following the sudden collapse of the East Spar gas field in the North West Shelf. In this article, we analyse the impact of the gas price increase and demonstrate that despite being the most environmentally efficient conventional technology, natural gas combined cycle plant has been squeezed out of the market which in turn will increase forward electricity price risks to WA consumers through greater exposure to CO2 pricing in the long run.  相似文献
