This article empirically investigates the exposure of country-level conditional stock return volatilities to conditional global
stock return volatility. It provides evidence that conditional stock market return volatilities have a contemporaneous association
with global return volatilities. While all the countries included in the study exhibited a significant and positive relationship
to global volatility, emerging market volatility exposures were considerably higher than developed market exposures.

Do the Forward Sales of Real Estate Stabilize Spot Prices? 总被引:1,自引:0,他引:1

We examine the effect of forward sale (pre-sale) activities on the volatility of spot prices in the real estate market. The
abundance of pre-sales data and major changes in regulatory control on the pre-sale market during the 90's in Hong Kong allow
us to undertake empirical tests using Hong Kong's real estate data. Our results show that the volatility of spot prices increased
significantly after forward sales were severely dampened by regulatory control measures introduced in 1994, but decreased
again when the measures were partly relaxed in 1998. The results contribute to the long lasting debate on whether the introduction
of a futures market reduces the volatility of spot prices. Previous studies were mainly conducted in markets with low transaction
costs, notably financial markets. By utilizing the unique regulatory changes in the pre-sale market of Hong Kong, we are able
to conduct an experiment on the conditional volatility of spot prices in a high information-cost environment, thereby shedding
light on the important role of forward housing contracts in providing price expectation information for spot trading. 相似文献

This paper analyses the impact of exogenous national security related shocks on the time-varying volatility structure of the Greek stock market. Alternative autoregressive conditional heteroscedastic models are estimated, in order to identify the best fit that adequately describes return volatility behavior, testing symmetric as well as asymmetric innovation responses. An external national security related shock factor is included as well as a military crisis dummy, in order to depict possible implications for the conditional variance. The empirical findings appear to support a statistically significant impact of both national security related factors on the Athens stock market returns. 相似文献

Valuing high-dimensional options has many important applications in finance but when the true distributions are unknown or
complex, numerical approximations must be used. Approximation methods based on Monte-Carlo simulation show a steep trade-off
between estimation accuracy and computational efficiency. This article presents an alternative semi-analytic approximation
method for pricing options on the maximum or minimum of multiple assets with unknown distributions. Computational efficiency
is shown to improve significantly without sacrificing estimation accuracy. The method is illustrated with applications to
options on underlying assets with mean-reverting prices, time-dependent correlations, and stochastic volatility

This study investigates the stock-market reaction to layoff announcements where more than 1000 workers are affected. We employ a dummy variable regression (DVR) version of the market model and compare the results obtained using ordinary least squares (OLS) versus exponential GARCH (EGARCH), and value-weighted (VW) versus equally weighted (EW) market index. We find that the stock market responds negatively to layoffs attributed to low demand. We also find that contrary to prior research, the market reacts positively to restructuring-related layoffs on the announcement date. This pattern of market reaction is observed regardless of the market index used or the parameter estimation methods employed, although the empirical results indicate that using EGARCH/VW market index tends to generate fewer statistically significant test results and smaller (in the absolute size of the cumulative) abnormal returns (ARs). Taken together, our study provides additional support for the claim that studies of stock-market reaction to corporate events must account for the time variation in return volatility. Ignoring these could result in erroneous inferences. 相似文献

Inflation expectations play a key role in determining future economic outcomes. The associated uncertainty provides a direct gauge of how well‐anchored the inflation expectations are. We construct a model‐based measure of inflation expectations uncertainty by augmenting a standard unobserved components model of inflation with information from noisy and possibly biased measures of inflation expectations obtained from financial markets. This new model‐based measure of inflation expectations uncertainty is more accurately estimated and can provide valuable information for policymakers. Using U.S. data, we find significant changes in inflation expectations uncertainty during the Great Recession. 相似文献

The literature has long agreed that the DMP model (after Diamond 1982, Mortensen 1982, Pissarides 1985) with search and matching frictions in the labor market can deliver large volatilities in labor market quantities, consistent with empirical data, only if there is at least some wage stickiness. I show, however, that the model can deliver nontrivial volatilities without wage stickiness, as long as it has price dispersion and nonzero long‐run inflation rates. I find that by keeping inflation at a positive rate, monetary policy may be accountable for the large standard deviations observed on labor market variables. In addition, the Shimer (2005) puzzle disappears under monetary policy shocks. 相似文献

This paper proposes a cluster HAR-type model that adopts the hierarchical clustering technique to form the cascade of heterogeneous volatility components. In contrast to the conventional HAR-type models, the proposed cluster models are based on the relevant lagged volatilities selected by the cluster group Lasso. Our simulation evidence suggests that the cluster group Lasso dominates other alternatives in terms of variable screening and that the cluster HAR serves as the top performer in forecasting the future realized volatility. The forecasting superiority of the cluster models are also demonstrated in an empirical application where the highest forecasting accuracy tends to be achieved by separating the jumps from the continuous sample path volatility process. 相似文献
