We examine the predictive power of implied volatility in the commodity and major developed stock markets for the implied volatility in individual BRICS stock markets. We use daily data from March 2011 to October 2016 and employ the newly developed Bayesian Graphical Structural Vector Autoregressive (BGSVAR) model of Ahelegbey et al. (2016). Evidence suggests that the predictability of individual implied volatilities in BRICS is generally a function of both global and within the group stock market implied volatilities, and that the role of commodity market volatility is marginal, except for South Africa. Important implications for policy-makers and portfolio-managers are discussed.  相似文献

We investigated the relationship between stock prices and exchange rates in eleven emerging markets over the period of 1988 to 2014 using cointegration methodology and multivariate granger causality tests. We find that in emerging markets, the inner-financial structure, which reflects the proportion of direct financing and indirect financing, plays an important role in the link between exchange rates and stock prices. For ten out of the eleven emerging markets studied, the financial structure had a significant impact, either through the flow channel or stock channel. The effects of financial-economic structure (FIR) were much smaller.  相似文献

In contrast to some recent research, this article finds that regression approach futures hedge ratios are stationary. It shows that a previous study's failure to reject the random walk null hypothesis was due to its small sample size and the overlapping hedge ratio calculation approach's bias toward accepting the random walk hypothesis. The impact of overlap on the Dickey-Fuller full model intercept and slope estimates is demonstrated analytically and numerically. Finally, the article shows that out-of-sample hedging performance is not significantly improved by updating the hedge ratios. © 1998 John Wiley & Sons, Inc. Jrl Fut Mark 18:851–866, 1998  相似文献

Under the efficient market hypothesis, the stock price incorporates the full value of a firm’s advertising. If so, advertising spending should not be associated with future abnormal stock returns. Nevertheless, from 1995 to 2015, advertising spending often leads to abnormal stock returns the following year. The strongest results surface for consumer goods and services where advertising used to build brand equity can carryover from one year to the next. No significant differences arise for healthcare, industrial goods, or retailer advertising. Healthcare and industrial goods advertising is often modest. Retailer advertising that builds traffic should have little if any carryover into the following year. These results may help marketing managers defend an advertising budget whose benefits carryover into the following year, but hurt current profits. Having more investment analysts on Wall Street with a marketing background should help reduce this overly conservative “wait and see” discount for carryover advertising.  相似文献

We examine the performance of trend following strategies in Chinese commodity futures markets. We provide evidence that trend following‐based technical trading rules yield better performance than the buy and hold strategy on both individual contracts and sorted portfolios. The outperformance is robust to transaction costs, data frequency, sub‐prime crisis, shorting constraint, delayed execution, liquidity and parameters. Finally, the profitability of the trend following strategy may be subject to data snooping bias.  相似文献

This paper studies the impact of the nonfinancial disclosure on firm value for a large sample of Indian firms, arguably emerging market with poor investor protections and legal enforcement. We proxy the nonfinancial disclosure by the Bloomberg score on the extent of a firm's Environmental, Social, and Governance disclosures, and find positive valuation effects associated with the nonfinancial disclosure. We find the nonfinancial disclosure is more valuable to standalone firms compared to business group firms. This paper shows that the positive valuation effects associated with the nonfinancial disclosure are attributable to lower cost of funds and higher operating cash flows.  相似文献

Do innovation spillovers impact employment and skill upgrading?   总被引:1,自引:0,他引:1  
So far, the research on impact of innovation on employment and skills focused on effects within firms and sectors. Little attention was paid to the influence of interlinkages between sectors as a source of employment change. The main contribution of this paper to the field refers to broadening the analysis of innovation impacts to innovation spillovers from vertically linked sectors on firms' employment and skill change in user industries. The empirical analysis conclusively demonstrates an important role of innovation spillovers in the economy. Firms' employment growth is shown to benefit significantly from spillovers of product innovations in manufacturing and knowledge-intensive services. Similarly, firms that are subject to increased spillovers of product innovations as well as marketing and organisational innovations are more likely to upgrade their skill composition. Conversely, employment growth and skill composition of firms seem to be negatively affected by spillovers of process innovations in vertically linked sectors.  相似文献

Experts have long discussed and empirically investigated whether speculative activity increases volatility on commodity futures markets. Little empirical research, however, analyzes the role of speculators on commodity futures markets in China. Using time-varying vector autoregression models with stochastic volatility, this paper investigates for four heavily traded metal and agricultural contracts, how the relationship between returns volatility and speculation evolves over time. Our findings indicate that speculative activity has little to no impact on volatility. On the contrary, for all commodities examined, returns volatility seems to amplify speculation.  相似文献

This study empirically investigates the link between global companies' brand strength and consumers' actual purchase behavior by considering online purchasability and the geographical area in the context of boycott campaigns. To test the hypotheses, we employ a hierarchical multiple regression model using online survey data collected from 571 South Korean consumers. Our findings reveal that online purchasability with strong brand strength could be a beneficial strategy for global companies to increase consumers’ actual purchase behavior. Further, non-metropolitan consumers show an increase in actual purchase behavior as compared to metropolitan consumers. This study has implications for global companies to adequately respond to unexpected consumer boycotts.  相似文献

We analyze the influence of political connections on firms' access to capital and the ensuing effect on the cost of raising capital. Using a dataset of 413 IPOs from 2009 to 2012, we exploit a research setting where government is still highly involved with the process. We find that firms rely on political connections to reduce IPO rejection risk as a firm's political connections are positively associated with the propensity of obtaining approval for an IPO. We further find that political connections are negatively associated with the cost of IPO and connected firms appear to perform better subsequent to their IPOs.  相似文献

This article challenges the assumption that the factors associated with the self-employment choices of women differ from those of men; specifically, we test the extent to which women are influenced by standard economic factors compared with family and social issues. We find that economic factors influence the self-employment choices made by men and by women in the long and short-run. Although some findings were sensitive to the chosen self-employment measure our short-run findings, in particular, are at variance with the interpretation that self-employed women are less likely to be influenced by economic factors than their male counterparts. Consequently, we argue that gender-based explanations have exaggerated the importance of social factors in the self-employment choices made by women.  相似文献

This paper examines whether gold or the US dollar is a safe haven for emerging stocks. By calculating the low-high tail dependence between markets via copulas and the downside risk gains of portfolios, we find that both gold and the US dollar can serve as a safe haven for emerging stocks; that the US dollar is better than gold in most cases, while its superiority in hedging infinitely extreme risks is weakened in the subsample of global financial crisis and the out-of-sample; and that the downside risk gains offered by the US dollar for China and Thailand are very attractive.  相似文献

The objective of this paper is to examine the effects of knowledge about manipulated online product reviews on the effectiveness of such reviews in influencing consumers' product evaluations. The results of two empirical studies show that consumers clearly differ with regard to their knowledge that product reviews can be manipulated and that consumers who have such knowledge are less influenced in their product evaluations by reviews, specifically by negative ones. Furthermore, the effects of negative reviews are even weaker when consumers acquire their knowledge through a highly credible source (compared to a less credible source).  相似文献

Stakeholders’ engagement with corporate messages is crucial for companies that want to increase their social media coverage. However, our understanding of the content-related factors that drive stakeholders’ engagement is still poor. Drawing from the literature on news selection and distribution, this paper explores whether the relevant news values that are already found in corporate messages could also explain greater engagement in social media. In particular, six news factors were examined in a sample of 2331 tweets that were posted by the Euro Stoxx 50 companies. The results show that four news factors (in particular, Prominence, Entertainment, Immediacy, and to a lesser extent Human interest) play a role in the drive of content sharing through retweets and favorites. Additionally, the inclusion of hashtags and media content helps increase retweets and favorites. Finally, we observe differences among industries. In particular, firms operating in business-to-business industries obtain less reach through sharing. The implications of these results are relevant for social media strategists as they suggest avenues to increase followers’ engagement with company-produced content.  相似文献

We examine competing explanations, based on risk and behavioral models, for the profitability of stock selection strategies in emerging markets. We document that both emerging market risk and global risk factors cannot account for the significant excess returns of selection strategies based on value, momentum and earnings revisions indicators. The findings for value and momentum strategies are consistent with the evidence from developed markets supporting behavioral explanations. In addition, for value stocks, the most important behavioral bias appears to be related to underestimation of long-term growth prospects, as indicated by above average earnings revisions for longer post-formation horizons and by quite rapidly improving earnings growth expectations. Furthermore, we find that overreaction effects play a limited role for the earnings revisions strategy, as there is no clear return reversal until five years after portfolio formation, setting this strategy apart from momentum strategies.  相似文献

This study looks at the market impact of recent regulatory changes in Canada that provide for trading halts on individual stocks that experience large upside or downside movements. The focus is on all stocks traded on the Toronto Stock Exchange since the inception of the single‐stock circuit breaker rule (SSCB) in February 2012, to replace the short‐sale uptick rule. The results support pricing efficiency: material information that caused the circuit breaker is incorporated in stock prices on the day of the halt (neither overreaction nor underreaction), with no decline in market liquidity. Using trade‐by‐trade data constructed on five‐minute trading intervals, we refine the daily results, and show that shocks in realized volatility are focused in the 10‐minute trading interval surrounding the halts. While circuit breakers provide a limited safety net for investors when their stocks are subject to severe volatility, they do not allow for a quick turnaround for stocks experiencing severe price decline events.  相似文献

There has been a shift towards providing a seamless consumer journey experience in the retail industry, resulting from a customer-centric approach. In the new paradigm, channels are becoming more intertwined and intricate, and ultimately more companies are embracing the omni-channel alternative. However, this alternative seems to be difficult for companies to operationalize. Such difficulty is due to several factors that need to be identified and disentangled. Therefore, in this study we consider the barriers faced by firms and categorize them to understand whether it is possible to successfully implement the omni-channel approach. We use four case studies to investigate the obstacles, looking for brands that operate in different industries, represent different levels of channel integration and have had different experiences in the retail industry. We identify two types of obstacles: internal, including operational and strategic barriers (employee-related, organizational and vision-related factors); and external, including product-related, customer-related, legal and competitive drivers. We propose a theoretical framework that shows the scope of industry drivers affecting the implementation of an omni-channel strategy, as well as a model showing how internal and external factors affect the evolution of channel integration. As a result, we claim that for some industries and products, even if internal obstacles are significantly reduced, because of industry drivers, successful implementation of the omni-channel approach may ultimately be a utopia.  相似文献

The purpose of this paper is to examine the role of the product placement in the film on purchase intention, attitude and change in perception. For this study, we selected recently released film and interviewed the film goers after he came out of the theatre through intercept technique. The products have improved brand recall, perception, and brand recommendation, ‘feeling’ towards brands, association and purchase intentions which are our dependent variables in our study. Brand image, country image, value for money and culture affects these dependent variables as per our present study. Low involved products get more mileage from product placement. The effect of product placement in low and high involved brand is explained for the first time through application alternative hierarchy’s theory of Ray et al., Theory of Hovland et al. and Gestalt theory of familiarity. Our paper bridges the gap between theory and practice by suggesting improvement in product placement in non –traditional media like film.  相似文献

It seems reasonable to expect financial market efficiency to be related to the economic development level. We study a 16 year sample, covering 22 countries. The Hurst–Mandelbrot–Wallis rescaled range is our efficiency measure, which we apply to returns and volatility. We find strong evidence of long memory persistence in volatility over time, which is unsurprising. However, unlike previous researchers, we could not find evidence of rescaled ranges trending down over time. However, we introduce an alternative measure of economic development, namely, whether FTSE (2011) classify an emerging market as ‘advanced’ or ‘secondary’. This measure shows greater efficiency in returns and volatility for ‘advanced’ emerging markets.  相似文献
