Purpose Might the impact of the global economic policy uncertainty (GEPU) and the long-term bond yields on oil prices be asymmetric? This paper aims to consider the effects of the GEPU and the US long-term government bond yields on oil prices using quantile-based analysis and nonlinear vector autoregression (VAR) model. The author hypothesized whether the negative and positive changes in the GEPU and the long-term bond yields of the USA have different effects on oil prices. Design/methodology/approach To address this question, the author uses quantile cointegration model and the impulse response functions (IRFs) of the censored variable approach of Kilian and Vigfusson (2011). Findings The quantile cointegration test showed the existence of non-linear cointegration relationship, whereas Granger-causality analysis revealed that positive/negative variations in GEPU will have opposite effects on oil prices. This result was supported by the quantile regression model’s coefficients and nonlinear VAR model’s IRFs; more specifically, it was stressed that increasing/decreasing GEPU will deaccelerate/accelerate global economic activity and thus lead to a fall/rise in oil prices. On the other hand, the empirical models indicated that the impact of US 10-year government bond yields on oil prices is asymmetrical, while it was found that deterioration in the borrowing conditions in the USA may have an impact on oil prices by slowing down the global economic activity. Originality/value As a robustness check of the quantile-based analysis results, the slope-based Mork test is used.

Purpose The paper aims to investigate the impact of economic policy uncertainty (EPU) (i.e. uncertainty due to government policies) on fine wine prices. Design/methodology/approach The paper uses the Baker et al. (2016) monthly news-based measure of EPU for the leading wine markets: the USA, the UK, France, Germany and China in conjunction with monthly fine wine pricing data from the London International Vintners Exchange (Liv-ex). The wine sub-indices used are the Liv-ex 500 (Bordeaux), Burgundy 150, Champagne 50, Rhone 100, Italy 100, California 50, Port 50 and Rest of the World 50. The Prais–Winsten and Cochrane–Orcutt regressions are used for our analyses to correct for effects of serial correlation. Time lags are chosen based on the appropriate information criterion. Findings Changes in EPU levels negatively impact changes in the Liv-ex 500 index for all our leading wine markets except France, the Champagne 50 index for the UK and the Burgundy 150 and the Rhone 100 indices for Germany, with the effects being significant for at least up to a quarter before EPU is detected. The authors did not find significant results for the EPU of France. Practical implications The paper aims to provide insights into whether EPU creates opportunities or threats for investors and wineries. Originality/value A forward-looking news-based EPU measure is used to gain insights into how the different Liv-ex sub-indices react to increases in uncertainty centered around government policies across a sample of different countries.

Purpose This paper aims to explore the impact of investor sentiments on economic policy uncertainty (EPU). The analysis also considers the momentum effect, stock market returns volatility and equity pricing inefficiencies across markets, which, to the best of the authors’ knowledge, has not been addressed in the literature. The role of these control variables has collectively been considered to have important behavioral implications for international investors Design/methodology/approach Quantile regressions are used for estimation purpose, as it provides robust and more efficient estimates rather than those coming from the traditional regression model. Findings The momentum effect is negative and significant only at higher quantiles, while oil prices are positive and significant across all quantiles. The exchange rate exerts a negative and significant effect on EPU, whereas equity price volatility (i.e. investor sentiment) exerts a negative and significant impact on EPU in most of the quantiles. Research limitations/implications The results have important implications for international investors and policymakers, especially in terms of the breakdown of economic policy uncertainty across different sample markets. The breakdown of complete sample period into sub-samples acts as a robust analysis and documents the similarity of the results for the Asian and developed markets cases, but not in the case of the European markets. Practical implications The findings imply the importance of financial stability that impacts the accumulation of systemic risks and adds smoothness to the financial cycle in particular geographical areas. Originality/value The contribution of this paper is threefold. First, existing literature highlights and empirically tests the impact of economic policy uncertainty on different market, macro-economic and global control variables. The analysis, however, performs it in the reverse order, i.e. analyzing the impact of the momentum effect (investor sentiment variables), equity market inefficiencies and volatility (market variables) and exchange rates and Brent oil (control variables). Second, to check the sensitivity of economic policy uncertainty, the analysis analyzes a wide range of markets, segregated as emerging, developed and European regions over the sample period to generate region-wise implications. Finally, the analysis explores the relationship of aforementioned variables with economic policy uncertainty keeping in view the non-linear structure and prior evidence and investor sentiments and economic policy uncertainty in the regression model.


Subject Economic turmoil in the South Caucasus. Significance Economic performance has been affected by two major external factors: turmoil in Russia, which remains a significant economic partner, and declining oil prices. While lower imported fuel bills are positive for Armenia and Georgia, there are second-round negative implications, through the impact on economic activity in Russia. Impacts Lower oil prices will lead to some cuts on infrastructure spending in Azerbaijan but these will be limited. Armenia will suffer the most from the Russian turmoil, but the positive impact of domestic factors will prevail in 2015. Georgia's more diversified economic links make it more resilient to Russian shocks.

Purpose This study aims to examine the spillover effects of trans-Atlantic macroeconomic uncertainties on the local stock market returns in the USA and eight selected European countries, namely, Germany, France, Spain, Italy, Greece, Ireland, Sweden and the UK, during the 2000-2019 period. Design/methodology/approach This paper applies the dynamic conditional correlation multivariate GARCH model (i.e. multivariate generalized autoregressive conditional heteroskedasticity model or DCC MGARCH) to examine the potential existence of the spillover from the uncertainty of the USA to EU stock markets and vice versa. To capture different dynamic relationships between multiple time-series variables following different regimes, this paper applies the Markov switching model to the stock returns of both the USA and the eight major stock markets. Findings The increases in US uncertainty have significant negative impacts on all EU stock returns, whereas only the increases in the uncertainties of Spain, Ireland, Sweden and the UK have significant negative impacts on US stock returns. Notably, the economic policy uncertainty (EPU) in the USA has a dynamic effect on the European stock markets. In a bear market (State 1), the increases in the EPU of the USA and EU have significant negative impacts on EU stock returns in most cases. However, only the increase in US EPU has significant negative impacts on EU stock returns in bull markets (State 2). Reciprocally, the increases in the EU EPUs of Germany, Spain and the UK have significant impacts on US stock returns in bear market. Originality/value The observations challenge the conventional wisdom according to which only larger economies can lead the smaller counterparts. The findings also highlight the stronger dependence of the US stock market on international macroeconomic uncertainty.

PurposeMany studies have examined the antecedents of firms' strategic change on a micro and meso level, but few studies have explored it from the macrolevel (e.g. economic policy uncertainty) perspective. This research draws attention to the impact of economic policy uncertainty on firms' strategic change.Design/methodology/approachThis research empirically tests hypotheses based on a sample of listed firms in China during the period between 2010 and 2017.FindingsBased on real options theory, the authors theorize and find that economic policy uncertainty will negatively affect firms' strategic change through the mediating effect of CEO turnover. Moreover, organizational inertia will strengthen the negative impact of economic policy uncertainty on CEO turnover and will weaken the positive impact of CEO turnover on firms' strategic change.Originality/valueFirst, this research contributes to the strategic change literature by demonstrating the important impact of economic policy uncertainty on firms' strategic change. Second, this research expands the literature on the economic consequences of economic policy uncertainty. Third, this research clarifies the path and boundary conditions of economic policy uncertainty affecting strategic change by introducing the mediating effects of CEO turnover and the moderating effects of organizational inertia.

Purpose – The recent economic crises have attracted attention to the issue of international equity co-movements and correlations. Using data from 1980 to 2010, the authors examine the international co-movements of both real economic activity, as reflected in industrial production and the gross domestic product (GDP), and financial activity, as reflected in equity market returns. While classic symmetric co-integration tests do not reject the hypothesis of no co-integration, the authors find evidence of asymmetric co-integration in these three variables between the USA and the rest of the Group of Seven (G7) countries. The momentum threshold autoregressive (M-TAR) model captures the nature of the asymmetry most effectively and is the most applicable model for adjustment to long-term equilibrium. This model suggests that the path of adjustment to long-run equilibrium is somewhat different when the price differential is decreasing than when it is increasing. These findings imply that the benefits of asset diversification for investors with a long horizon might be limited in scope. Design/methodology/approach – This work is based on the theory of integrated time series. The authors use symmetric and asymmetric co-integration tests to market indices, as well as to monthly industrial production statistics and quarterly data about the GDP. In line with the financial economic literature, the authors select the GDP as a proxy that reflects the real economy and share prices to mirror the financial sector of the economy. Because no monthly data exist about GDP, the authors use instead the industrial production. Both variables cover the period from January 1980 to June 2010. Findings – The overall findings demonstrate that the USA and the rest of the G7 countries are not symmetrically co-integrated with respect to the GDP. Indeed, they are asymmetrically co-integrated. These findings may explain the additional important result that the majority of equity markets are also asymmetrically co-integrated with the USA. Research limitations/implications – The co-movements of the equity markets and real economic activity imply that the benefits of asset diversification for investors with a long horizon might be limited in scope. In the short run, however, portfolio diversification can be more beneficial due to the short-term fluctuations that may derive from the asymmetric correction process. Originality/value – Prior research on co-movements has focused mainly on studying the correlations among international equity markets by analyzing conditional correlations or using symmetric co-integration methods; the authors test the existence of a long-term relationship between economic variables with respect to the USA and the rest of the G7 countries using a threshold co-integration model.

Purpose The global financial crisis of 2007-2008 prompted a significant debate on corporate governance and shareholder empowerment. A question arises as to whether shareholders ought to be further empowered to have a greater influence over the companies’ activities. Yet, it is not self-evident that shareholder empowerment ensures better-run companies’ corporate activities. Thus, the purpose of this paper is to critically examine, identify and explain the corporate regulation forms and control collectively to evaluate the effectiveness of shareholder empowerment fully. Design/methodology/approach To do so, this paper sets out a comparative analysis approach between two jurisdictions, the UK and Delaware in the USA. The paper further addresses by undertaking three case studies; Barclays Plc which illustrated the Comply or Explain role, AVIVA (2012) that concentrated on the impact of the shareholder revolt, and the case of Hills Stores Co. v. Bozic (2000), which involved a claim brought by shareholders on the grounds of a breach of fiduciary duty. Findings This paper argues that the shareholder empowerment theoretically provides an effective means through which corporate activities can be regulated. However, to do this, account must be taken that a distinction should be made between long-term and short-term investors to encourage shareholder engagement by responsible long-term investors. Furthermore, the shareholders can exercise their powers effectively and influence the Board’s decision to award executive compensation. Originality/value This paper offered two distinct contributions: assessing whether in times of crisis shareholder empowerment represents a way to regulate corporate activities and by assessing the distinction between the perception of shareholder empowerment and the reality in practice.
