This article explores the market response of deep discount corporate bonds to the reduction in the capital gains tax rate incorporated into the Revenue Act of 1978. Such tax change should have increased the desirability of assets acquired for capital gains potential, such as deep discount bonds. Examining a time series of prices and returns for a sample of deep discount corporate bonds and a control group of comparable duration and credit risk corporate bonds selling at or near par did indeed provide evidence of a market price reaction. Moreover, the price changes for the deep discount bonds occurred well in advance of the implementation of the tax change.  相似文献

Estimates of the welfare losses associated with food recalls typically assume the announcement causes demand to shift, or the willingness‐to‐pay (WTP) falls for all quantity levels. Several researchers, however, have observed evidence of a rotation as well, where WTP rises for some consumers and falls for others. Preference heterogeneity theory implies that this observation results from an increase in the dispersion of demand. We test this theory using Centers for Disease Control and Prevention announcement data and Nielsen Homescan panel data for the fresh produce category. We find that the rotation effect cannot be disregarded, but is still dominated in welfare calculations by the shift effect of a recall announcement.  相似文献

We examine the implications of changing competitive dynamics in global information and communications technology (ICT) markets for government demand-steering policies whose goal is local rents. Both computing and telephony are undergoing changes in global industry structure and changes in the nature of competition. The convergence of computing and telephony and the rapid technological change (and accompanying technological uncertainty) driving this convergence reinforce trends toward vertical competition. The emergence of global ICT markets lowers entry barriers, likely encouraging government-supported local entrants into global ICT markets. There are, however, strongly offsetting disadvantages. The underlying economics of ICT markets under vertical competition will work to reinforce the dominant position of U.S.-based incumbents in many segments. The prospects for exports, command of rent-related standards, and large rents from exports are not very bright. We expect to see far more demand-steering attempts than successes. J. Japan. Int.

An analysis of changes in domestic production, foreign trade and aid in Syria from 1970 to the late 1980s reveals a marked contrast between the two decades. In the 1970s per capita incomes expanded rapidly due to the regional oil boom. Demand for food grew quickly and, despite respectable supply growth, food imports as a percentage of consumption increased. During the 1980s income per capita stagnated and demand growth slowed. At the same time a series of poor rainfall years reduced domestic supply growth and increased production variability, yet food imports showed no trend  相似文献
