We suggest a Markov regime-switching (MS) Beta-t-EGARCH (exponential generalized autoregressive conditional heteroscedasticity) model for U.S. stock returns. We compare the in-sample statistical performance of the MS Beta-t-EGARCH model with that of the single-regime Beta-t-EGARCH model. For both models we consider leverage effects for conditional volatility. We use data from the Standard Poor’s 500 (S&P 500) index and also a random sample that includes 50 components of the S&P 500. We study the outlier-discounting property of the single-regime Beta-t-EGARCH and MS Beta-t-EGARCH models. For the S&P 500, we show that for the MS Beta-t-EGARCH model extreme observations are discounted more for the low-volatility regime than for the high-volatility regime. The conditions of consistency and asymptotic normality of the maximum likelihood estimator are satisfied for both the single-regime and MS Beta-t-EGARCH models. All likelihood-based in-sample statistical performance metrics suggest that the MS Beta-t-EGARCH model is superior to the single-regime Beta-t-EGARCH model. We present an application to the out-of-sample density forecast performance of both models. The results show that the density forecast performance of the MS Beta-t-EGARCH model is superior to that of the single-regime Beta-t-EGARCH model.  相似文献

We investigate the impact of banking deregulation during the 1990s on consumer welfare. We estimate a spatial model of consumer demand for retail bank deposits that explicitly accounts for consumer disutility from distance traveled. This is important given the substantial changes in banks' branch networks observed in the data. Our model indicates that cross-price elasticities between banks whose branches are close to consumers (‘close’ banks) are larger than those between ‘far’ banks and more than double the cross-price elasticity of ‘close’ banks with respect to ‘far’ banks. We distinguish between thrifts and other banks and find that within-thrift competitive effects are stronger than within-bank effects or those between thrifts and banks. We use our estimates to predict the effect of changes in market structure on consumer welfare following the branching deregulation of the Riegle–Neal Act of 1994. Our results indicate that the median household gained around $60 per year from the changes. Approximately two thirds of the gains come from within-market changes in market structure. The gains were greater in markets with high initial numbers of banks than elsewhere.  相似文献

Using the capital market approach and the equity price data of 14 listed Chinese banks, this empirical study finds that there is a positive relationship between bank size and foreign exchange exposure. This relationship may reflect the larger foreign exchange operations and trading positions of larger Chinese banks and their significant indirect foreign exchange exposure arising from impacts of the renminbi exchange rate movements on their customers. Empirical evidence also suggests that the average foreign exchange exposures of state-owned and joint-stock commercial banks in China are higher than those of banks in Hong Kong, notwithstanding their limited participation in international banking businesses compared with their Hong Kong counterparts. It is also found that negative foreign exchange exposure is prevalent for larger Chinese banks, suggesting that an appreciation of the renminbi tends to reduce their equity value. It is therefore likely that the banking sector's performance will be hampered. Together with the fact that decreases in equity values generally imply a higher default risk, the effects of different scenarios of renminbi appreciation on the default risk of Chinese banks should therefore be closely monitored.  相似文献

Intraday information efficiency on the Chinese equity market   总被引:1,自引:0,他引:1  
Bid-ask spread is a direct measure of information asymmetry. As such, it can be used to evaluate information efficiency. In this paper, we show that both the quoted and effective spreads on the Shanghai Stock Exchange are extremely high at the open, decrease over the trading day, and experience a small rebound at the close. The spread decreases with share volume, daily trades, and market capitalization, but increases with average trade size. We further examine the beta using the unbiasedness regression from Biais et al. [Biais, B., Hillion, P., Spatt, C. (1999). Price discovery and learning during the pre-opening period in the Paris Bourse. Journal of Political Economy, 107, 1218–1248] and find that intraday prices are efficient and unbiased for more liquid stocks. This suggests that liquidity prompts information-motivated trading, which, in turn, improves information dissemination. Moreover, our findings indicate that small and medium trades are more likely to facilitate the formation of efficient prices at the open and close of the market, while large trades play a more important role during the other trading periods.  相似文献

This article provides a quantitative assessment of contemporary beliefs about historical events by econometrically identifying ‘break points’ in China's domestic bond market from 1921 to 1942. We find that these ‘break points’ usually coincided with the events highlighted by the Shanghai Newspaper—an influential daily newspaper produced during the time of the Republic of China. These events are also generally considered to be crucial by historians—for example, the Japanese invasion of Manchuria and the outbreak of the Second Sino‐Japanese War. However, some events to which historians attach great importance, such as the conflicts between Nationalists and Communists in the 1930s, were not reflected in the bond market and did not attract much media attention. Some events, such as the Sino‐Japanese ceasefire in Tanggu in 1933, were thought to be crucial by contemporaries, but have been downplayed by later observers.  相似文献

The financial and economic crisis of 2008 and 2009 took a heavy toll on the South African economy. The economy contracted for the first time since 1998 and entered recession during the fourth quarter of 2008. The gross domestic product contraction was soon transmitted to the labour market. Between the second quarters of 2008 and 2009, employment fell by 3.8%. However, not all individuals were hit with the same intensity. Using panel data from a quarterly labour force survey unique in the African context, we find that human capital (i.e. education as years of schooling and workforce experience) provided a buffer against the shock. After controlling for observable characteristics, education and experience showed the potential to entirely offset the effect of the recession on the likelihood of employment. This has important policy implications, as it strengthens the case for strategic investments in human capital and helps identify the unskilled as having the greatest need for social safety net interventions during a recession.  相似文献

A sports lottery in Korea presents a unique opportunity for comparing a parimutuel‐type sports lottery market against a bookmaker market outside the realm of horse racing. Using two‐ and three‐game soccer final‐score betting in the sports lottery market in Korea, which features matches in the English Premier League, we compare winning payoffs in this parimutuel‐type sports lottery against corresponding payoffs from an established bookmaker market in the United Kingdom. We find that for outcomes with relatively high payouts (that is, lower‐probability events), winning bets placed in the sports lottery market have greater payoffs than corresponding bets placed in the bookmaker‐based market. However, the opposite is true for outcomes with relatively low payouts (that is, higher‐probability events). Results suggest that participants in the sports lottery market tend to bet more toward high‐probability events than the amount implied by the bookmaker's odds. Results also suggest that the favorite‐longshot bias is still present in the bookmaker market, even when there is less threat of privately informed bettors than in horse racing.  相似文献
