This paper presents a simple new method for measuring “wealth effects” on aggregate consumption. The method exploits the stickiness of consumption growth (sometimes interpreted as reflecting consumption “habits”) to distinguish between immediate and eventual wealth effects. In U.S. data, we estimate that the immediate (next quarter) marginal propensity to consume from a $1 change in housing wealth is about 2 cents, with a final eventual effect around 9 cents, substantially larger than the effect of shocks to financial wealth. We argue that our method is preferable to cointegration‐based approaches, because neither theory nor evidence supports faith in the existence of a stable cointegrating vector.  相似文献

This paper investigates volatility spillover in the Nigerian sovereign bond market arising from oil price shocks, using Vector Autoregressive Moving Average ‐ Asymmetric Generalized Autoregressive Conditional Heteroscedasticity (VARMA‐AGARCH) model. The paper covers the period March 22, 2011 to April 14, 2016 and makes use of the daily data of the Nigerian Sovereign Bond, Brent oil and West Texas Intermediate (WTI), respectively. We endogenously and sequentially detect structural break points using the test of Bai and Perron (2003) framework. In order to accurately estimate the model, we modify it by incorporating the break points into the VARMA‐AGARCH model, a process which if ignored would lead to model misspecification. The results obtained demonstrate a significant cross‐market volatility transmission between oil and sovereign bond market with ample sensitivity to structural breaks. The study also computes optimum weight portfolio and hedge ratio both with and without structural breaks and results equally indicate sensitivity to structural breaks.  相似文献

Motivated by the requirement under the Dodd-Frank Act that all large bank holding companies create a stand-alone, board-level risk committee, this paper investigates the association between such a committee and regulatory risk both before and during the financial crisis. I focus the analysis on the set of banks that did not have a risk committee in place prior to the Dodd-Frank Act, as these are the banks that were most affected by the regulation. I find that matched control banks with a risk committee in place had higher capital ratios during the financial crisis, but lower capital ratios during more stable economic conditions relative to the banks without a risk committee. This paper contributes to the literature by narrowly investigating the effects a board-level risk committee, by focusing on a risk measure that is of interest to the regulators who implemented the new regulation, and by documenting that this association changes over time which highlights the importance of estimating the effects of new regulations across different economic conditions.  相似文献

This paper analyses the connectedness network for commercial traders’ sentiment across agriculture, energy, metals and livestock futures markets. The findings find that: (a) producer/merchant/processor/user (PMPU) in agricultural and energy markets are mainly engaged in cross-hedging in the futures market, and most of them would avoid risks in these markets by operating in the metal markets, which can be considered safe for PMPU traders, and that the cross-hedging strategies may play the role of PMPU sentiment spillover across futures markets; (b) as index traders, the swap dealers operate more in two markets, namely between the agricultural and metal markets, or between the agricultural and energy markets; (c) the influence of geopolitical risks in some countries can affect the stability of energy markets, which in turn can cause PMPU system-wide connectedness.  相似文献

Using the Chinese stock market data from 1997 to 2013, this paper examines the “Sell in May and Go Away” puzzle first identified by Bouman and Jacobsen (2002). We find strong existence of the Sell in May effect, robust to different regression assumptions, industries, and after controlling for the January or February effect. However, part of the puzzle is subsumed by the seasonal affective disorder effect. We then construct a trading strategy based on this puzzle, and find that it outperforms the buy-and-hold strategy and could resist the market downside risk during large recession periods.  相似文献

We report international, style, and subperiod evidence for the other January effect (OJE) documented in Cooper et al. [2006. The other January effect. Journal of Financial Economics 82, 315–341]. When examining the OJE in 22 countries starting as early as 1801, we find that the spread between 11-month returns following positive and negative Januarys does tend to be positive. However, the spreads are rarely statistically significant and the returns of other calendar months exhibit similar subsequent 11-month return spreads. Further, the international OJE spreads and the OJE spreads in disaggregate U.S.-style portfolios are more related to the U.S. market-level January return, rather than the respective country-specific or portfolio-specific January return. Finally, the OJE is weaker over the 1975–2006 post-discovery period than over the 1940–1974 pre-discovery period. Our evidence indicates that the OJE is primarily a U.S. market-level-based phenomenon that has diminished over time, which suggests a ‘temporary anomaly’ interpretation.  相似文献

French banks and non‐financial companies issue index‐linked debt whose value at maturity is indexed to the CAC 40 or to a basket of European indices. This paper examines stock announcement effects associated with these bonds on three dates: the date the issuer's General Assembly decides future capital needs, the publication in the journal of the COB (the stock market board), and the issue date. We find the issuance of index‐linked debt has significant positive announcement effects on the issue date, which we attribute to its market‐completion property. In order to examine further whether market completion is at play, we decompose the value of the bond at issue into its straight bond and option values. We determine that the bonds are overvalued again supporting market completion.  相似文献

This article empirically tests the hypothesis that credit-screening standards can be first increasing and then decreasing in the quality of the bank's pool of potential borrowers, which in turn may vary through the business cycle or across different segments of the lending markets. A key implication is that banks with lending opportunities toward the middle of the quality spectrum can have loan portfolios that perform better than do the portfolios of banks with loan-origination opportunities that are either too weak or too strong. Using banks’ volume of secondary-market loan sales as a proxy for the richness of lending opportunities, I find an inverse U-shaped relation between the performance of banks’ loan portfolios and their activity in the loan sales market. The pattern deserves scrutiny for its policy implications, as many regulators hold the view that countercyclical variation in credit standards may have a destabilizing effect on business cycles.  相似文献
