This paper investigates whether global risk perceptions lead emerging market return volatilities. In so doing, we analyzed the period of interest in three parts to determine the effects of the changes in global risk perceptions on the volatility of emerging markets. We uncovered volatility spillover from risk perceptions to the MXEF returns before the crisis. Our results show that all the effects on emerging market volatilities are severed in 2008, during which MXEF follows a downward trend. However, we observe that volatility transmission emerges during the recovery period of MXEF again. Hence, risk perceptions should be considered while analyzing emerging markets.  相似文献

Motivated by the recent phenomenal growth in Islamic finance and the financialization of commodities, this study makes an initial attempt to investigate the risk–return profiles of optimized portfolios combining (a) Islamic equities with commodities and (b) conventional equities with commodities during the crises and noncrises periods. The findings tend to indicate that Islamic equity–commodity portfolios provide relatively higher diversification benefits than the conventional equity–commodity portfolios during the 1997 Asian Financial Crisis triggered by the financial sector compared to the 2008 global financial crisis triggered by the real housing sector. The findings further suggest that except for a few cases, commodities in general and gold in particular improve diversification benefits.  相似文献

Is the Risk of Bankruptcy a Systematic Risk?   总被引:6,自引:0,他引:6  
Several studies suggest that a firm distress risk factor could be behind the size and the book-to-market effects. A natural proxy for firm distress is bankruptcy risk. If bankruptcy risk is systematic, one would expect a positive association between bankruptcy risk and subsequent realized returns. However, results demonstrate that bankruptcy risk is not rewarded by higher returns. Thus, a distress factor is unlikely to account for the size and book-to-market effects. Surprisingly, firms with high bankruptcy risk earn lower than average returns since 1980. A risk-based explanation cannot fully explain the anomalous evidence.  相似文献

A large body of research has documented a positive relationship between different measures of sustainability—such as indicators of employee satisfaction and effective corporate governance—and corporate financial performance. Nevertheless, many investors still struggle to quantify the value of ESG to investment performance. To address this issue, the authors tested the effects of using different ESG filters on an investable universe that serves as the starting point for a fund manager. In this way, they attempted to determine the extent to which ESG data can add value to any investment approach, regardless of preferences towards sustainable investing. The authors report “an unequivocally positive” contribution to risk‐adjusted returns when using a 10% best‐in‐class ESG screening approach (one that effectively removes companies with the lowest 10% of ESG rankings), both on a global and a developed markets universe. More specifically, as a result of such screening, both the global and developed markets portfolios show higher returns, lower (tail) risk, and no significant reduction of diversification potential despite the reduction in the number of companies. Use of a 25% screening filter was also found to add value, especially by reducing tail risks, but with a larger deviation from the unscreened universe. Overall, then, the authors’ finding is that the incorporation of ESG information contributes to better decision‐making in every investment approach, with the optimal configuration depending on a fund manager's preferences and willingness to deviate from an unscreened benchmark.  相似文献

In an influential paper, Frankel and Lee (1998) conclude that the stock return predictability of the value‐to‐price ratio (V/P) results from market mispricing. This paper confirms whether the V/P reflects the rational risk premiums associated with the V/P factor or is better explained by market inefficiency. Following Daniel and Titman (1997), this paper examines whether the V/P characteristics or the V/P factor loadings predict stock returns. The findings show that the V/P loadings are positively associated with average returns even after controlling for the V/P characteristics in both time series and cross‐sectional tests. The overall results suggest that the mispricing explanation of the V/P effect is premature.  相似文献

Using monthly South African data for January 1990 through October 2009, this paper, to the best of our knowledge, is the first to examine the predictability of real stock return based on valuation ratios, namely, price-dividend and price-earnings ratios. We cannot detect either short-horizon or long-horizon predictability; that is, the hypothesis that the current value of a valuation ratio is uncorrelated with future stock price changes cannot be rejected at both short and long horizons based on bootstrapped critical values constructed from linear representations of the data. We find, via Monte Carlo simulations, that the power to detect predictability in finite samples tends to decrease at long horizons in a linear framework. Although Monte Carlo simulations applied to exponential smooth-transition autoregressive models of the price-dividend and price-earnings ratios show increased power, the ability of the nonlinear framework in explaining the pattern of stock return predictability in the data does not show any promise at either short or long horizons, just as in the linear predictive regressions.  相似文献

This paper examines two relationships using the bivariate generalized autoregressive conditionally heteroskedastic (GARCH) methodology. First, the relationship between equity returns of commercial banks, savings and loans (S&Ls) and life insurance companies (LICs), and those of the real-estate investment trusts (REITs), a proxy for the real-estate sector performance. Second, the relationship between conditional volatilities of the stock returns of these financial intermediaries (FIs) and that of REITs. The former relationship allows the spillover of returns between the real-estate and the financial intermediation sector to be analyzed. The latter allows an investigation of the prevalence, direction and strength of inter-sectoral risk transmission to be carried out. Several interesting results are obtained. First, the equity returns of the FIs considered follow a GARCH process and should be modeled accordingly. Second, as found in the literature, returns on REITs should be modeled using the Fama-French multiple factor model. However, this model has to be extended to incorporate a GARCH error structure. Third, all FI returns considered are highly sensitive to REIT returns and the effects are both statistically and economically significant. This is an indication that shocks to REITs returns spillover to the former markets. Fourth, spillover of increased volatility in the real-estate sector to S&Ls and LICs is significant but not to commercial banks.  相似文献

Social media is a particular communication platform which has witnessed an exponential growth in use and influence in recent years, democratising the communication process, and offering risk communicators a way of putting into practice those principles which are advocated to be at the core of risk management and communication. However, little is known about stakeholders’ willingness to embrace this new form of communication in a food crisis. The current study presented an exploratory investigation of the opinions of Irish stakeholders on the position of risk communication in a crisis, with a particular focus on understanding what application social media may have. In-depth one-to-one interviews were carried out with key stakeholders holding frontline positions in managing and communicating about risk in the food sector in Ireland. The stakeholders identified risk communication as a central activity in a food safety crisis, driven by an obligation to protect both consumer health and the reputation of the Irish food sector. Stakeholders relied primarily on risk communication to disseminate information in a crisis so to educate and inform the public on a risk and to prevent confusion and alarmism; most did not explicitly value two-way risk communication in a crisis. The ability to effectively manage future crises may depend on stakeholders’ willingness to adapt to the changing communication landscape, namely – their willingness to adopt social media and use it effectively. The findings indicate that the stakeholders interviewed are appreciative of the need to engage with social media in times of a food safety crisis. However, most valued social media as a one-way channel to help spread a message and there was little reference to the interactive nature of this medium. Implications for integrating social media into crisis risk communication strategies are discussed.  相似文献

A community survey examined factors affecting the trust of four groups involved in a high concern controversy over the risks posed by motor boats to the quality of a municipal water supply. In an effort at conceptual integration the survey results were used to examine the relationships between three concepts of trust. Perceived agreement in values between self and four controversy‐involved groups was found to be the most powerful predictor of trust of all four groups, as expected by the salient value similarity perspective. “Fairness” and “competency,” as expected by the “dimensions” of trust perspective were also found to be significant predictors of trust. However, judgments of “fairness” and “competency” were context specific as indicated by significant correlations with judgments of salient value similarity and self interests. This violates the assumption of universality of the “dimensions” of trust perspective. Judgments of similarity of values between self and the controversy‐involved groups were significantly correlated to self interests. This indicates a conceptual overlap between the salient values similarities perspective and the encapsulated trust perspective.  相似文献

Size has become a significant factor in explaining returns. According to the size effect, smaller capitalization stocks on average outperform larger capitalization stocks over long periods of time. This paper first documents the traditional size effect on the French market for the 1986–1998 period. It introduces a new proxy for size, free float, which is argued to be the appropriate measure of size and liquidity for most non‐US markets. Evidence is presented of a negative link between historical returns and free float. The link is significant even outside of the month of January, a notable divergence from results obtained on the NYSE. The rest of the paper is an attempt to take advantage of this 'ex‐post' phenomenon on an 'ex‐ante' basis, with an empirical study of the link between expected return, risk, and liquidity in a sample consisting of the main 150 stocks quoted on the Paris Bourse between January 1986 and January 1998. Liquidity premiums are estimated for portfolios from both a univariate and a multivariate perspective. The paper shows how risk and liquidity premiums can be used separately or in tandem for market timing and asset allocation. In all cases, the use of both premiums together leads to superior performance. Results confirm our measurements of liquidity and liquidity premiums and supply evidence that liquidity premiums together with risk premiums are useful in active asset management.  相似文献

We investigate the potential link between momentum in currency returns and global economic risk as measured by currency return dispersion (RD). Initial tests contribute to the exchange rate puzzle by showing that a common macroeconomic risk component in currency markets is present in global equity markets. Subsequent tests indicate that the spread on zero-cost currency momentum strategies is larger and highly significant in high RD states compared to low RD states. Also, the relation between these momentum payoffs and global economic risk appears to increase linearly in risk. Based on this evidence, we conclude that global economic risk as proxied by RD helps to explain currency momentum profits.  相似文献

There is increasing recognition in comparative risk assessment of the intrinsic subjectivity of fundamental framing assumptions and the consequent necessity for active participation in analysis by all interested and affected parties. Despite this, there remains considerable inertia in the implementation of these insights in formal policy making and regulatory procedures on risk. Here, the issue seems as often to be seen as a need for better 'communication' and 'management' as for better analysis, with attention devoted as much to the classification of divergent public perspectives as to techniques for direct stakeholder participation. Pointing to the fundamental methodological problems posed in risk assessment by the conditions of ignorance and Arrow's impossibility, the present paper contends that public participation is as much a matter of analytical rigour as it is of political legitimacy. It is argued that straightforward techniques such as multi-criteria and sensitivity analysis, along with a formal approach to diversification across portfolios of 'less risky' options, may go some way toward addressing these apparently intractable problems.  相似文献

We propose a quantile‐based measure of conditional skewness, particularly suitable for handling recalcitrant emerging market (EM) returns. The skewness of international stock market returns varies significantly across countries over time, and persists at long horizons. In EMs, skewness is mostly positive and idiosyncratic, and significantly relates to a country's financial and trade openness and balance of payments. In an international portfolio setting, return asymmetry leads to sizeable certainty‐equivalent gains and increases the weight on emerging countries to about 30%. Investing in EMs seems to be about expectations of a higher upside than downside, consistent with recent theories.  相似文献

We derive a formula for the expected return on a stock in terms of the risk‐neutral variance of the market and the stock's excess risk‐neutral variance relative to that of the average stock. These quantities can be computed from index and stock option prices; the formula has no free parameters. The theory performs well empirically both in and out of sample. Our results suggest that there is considerably more variation in expected returns, over time and across stocks, than has previously been acknowledged.  相似文献

In this paper the differences between forward and futures prices for the UK commercial property market are analyzed, using both time series and panel data. A first battery of tests establishes that the observed differences are statistically significant over the study period. Further analysis considers the modeling of this difference using mean-reverting models. The proposed models are then estimated with a number of alternative estimation methods and second stage statistical tests are implemented in order to decide which model and estimation method best represent the data.  相似文献

In this study, we test whether regional growth in 11 European countries depends on financial development and suggest the use of cost- and profit-efficiency estimates as quality measures of financial institutions. Contrary to the usual quantitative proxies of financial development, the quality of financial institutions is measured in this study as the relative ability of banks to intermediate funds. An improvement in bank efficiency spurs five times more regional growth then an identical increase in credit does. More credit provided by efficient banks exerts an independent growth effect in addition to direct quantity and quality channel effects.  相似文献

ABSTRACT

This article establishes a dynamic game with incomplete information to theoretically analyze the influence mechanism of information disclosure on systemic risk in the presence of a deposit insurance system. To verify the mechanism, we use panel data on 247 global banks in 41 countries during the period 2006 to 2015 in an empirical analysis. Our article finds that a high degree of information disclosure can reduce deposit insurance premiums and weaken the negative incentive from a bailout by regulatory authorities. Moreover, the effect of deposit insurance on financial stability is not apparent, but the synergistic effect of deposit insurance and information disclosure reduces bank systemic risk. Furthermore, different deposit insurance designs affect bank behavior, so it is crucial for bank supervisors to create proper deposit insurance systems, which are helpful in strengthening market discipline and preventing moral hazard thus contributing to a stable financial environment. Therefore, under the deposit insurance system, regulatory authorities should strive to improve the standard of information disclosure to ensure systemic stability.  相似文献

We build an equilibrium model to explain why stock return predictability concentrates in bad times. The key feature is that investors use different forecasting models, and hence assess uncertainty differently. As economic conditions deteriorate, uncertainty rises and investors' opinions polarize. Disagreement thus spikes in bad times, causing returns to react to past news. This phenomenon creates a positive relation between disagreement and future returns. It also generates time‐series momentum, which strengthens in bad times, increases with disagreement, and crashes after sharp market rebounds. We provide empirical support for these new predictions.  相似文献

Risk attitudes other than risk aversion (e.g. prudence and temperance) are becoming important both in theoretical and empirical work. While the literature has mainly focused its attention on the intensity of such risk attitudes (e.g. the concepts of absolute prudence and absolute temperance), I consider here an alternative approach related to the direction of these attitudes (i.e. the sign of the successive derivatives of the utility function).  相似文献
