This study empirically tests how and to what extent the choice of the sampling frequency, the realized volatility (RV) measure, the forecasting horizon and the time‐series model affect the quality of volatility forecasting. Using highly synchronous executable quotes retrieved from an electronic trading platform, the study avoids the influence of various market microstructure factors in measuring RV with high‐frequency intraday data and in inferring implied volatility (IV) from option prices. The study shows that excluding non‐trading‐time volatility produces significant downward bias of RV by as much as 36%. Quality of prediction is significantly affected by the forecasting horizon and RV model, but is largely immune from the choice of sampling frequency. Consistent with prior research, IV outperforms time‐series forecasts; however, the information content of historical volatility critically depends on the choice of RV measure. © 2010 Wiley Periodicals, Inc.

This paper presents evidence that the net current asset value rule developed by Ben Graham in 1930 is still profitable in the 1970s and early 1980s. The abnormal gain is not due to future mergers because both the merged and nonmerged subsamples have positive and statistically significant returns in the post-event period. 相似文献

The First Executive Corporation was the largest failure in the history of the life insurance industry. The company was one of the most aggressive purchasers of junk bonds through the 1980s and was the first of several large failures in the staid life insurance industry. In this article, we examine the effect of First Executive's failure on the value of companies in the life insurance industry. We find that the price of other life insurance companies' stock is negatively affected by the earnings announcement that preceded First Executive's failure. The magnitude of an individual company's reaction to First Executive's loss varies according to the proportion of the company's assets invested in junk bonds, the proportion of the company's assests invested in real estate, and the financial strength of the company as measured by A.M. Best's rating. 相似文献

Externalities generally are viewed as impacting land values rather than building values. Yet when locational obsolescence is attributed to externalities, the implication is that externalities impact primarily on building values. The presence of negative externalities generally does not determine whether a building suffers from locational obsolescence; the more general cause is a misallocation of land. At the market allocation, there is no locational obsolescence even in the presence of an externality, while at the optimal allocation only an externality can produce locational obsolescence. Because locational obsolescence can exist without externalities, an externality is not a necessary condition for locational obsolescence. Because an externality can be present without accompanying locational obsolescence, an externality also is not a sufficient condition for the existence of locational obsolescence. 相似文献

Abstract. The objectives of this paper are threefold. First, we critically survey and analyse the different methodologies that have been adopted in the rankings literature. Second, using journal articles included in the ECONLIT database and on the basis of two criteria – one based on citations and the other on perceptions of journal quality, we rank economics teaching departments in Australia and New Zealand for 1988–2002 and 1996–2002 and for individual academic economists for the periods 1988–2002, 1988–1995 and 1996–2002. Furthermore, we identify individual star performers and recognize them in a designated 'Hall of Fame' for 1988–2002. Third, our methodology enables us to make international comparisons on total and per capita bases. Previous multi-country ranking studies in economics do not rank economics departments. They provide rankings based on total publications in economics in universities regardless of whether the economists are in the economics departments or in other departments. Thus, no rankings on per capita bases are provided. We correct this shortcoming by providing total and per capita rankings and analysing the correlations between total and per capita rankings. This is the first study to examine whether the size of the economics department matters with regard to productivity. 相似文献

Derivative mortgage securities have proliferated since planned amortization and floating rate CMO classes were introduced in late 1986. Other recently created derivative securities include reverse floaters and deep-discount bonds of CMOs, CMO residuals, and stripped and senior/subordinated passthroughs. These securities, which are derived from fixed-rate mortgages, were created to meet investor demands for maturity certainly, interest rate and prepayment hedging, and enhanced credit. The rapid growth of derivative securities reflects expansion of the investor base for fixed-rate mortgages. It also suggests that these mortgages will continue to be a viable housing finance instrument in a volatile interest rate environment. For the future, the increased creation of derivative securities will make the secondary mortgage market more efficient, facilitating the funding of fixed-rate mortgage originations.The substance of this paper was originally written in late 1987 and many of the specific data reflect that time period. 相似文献
