Can both Bitcoin and gold serve as safe-haven assets? — A comparative analysis based on the NARDL model

This paper uses the nonlinear autoregressive distributed lag (NARDL) model to analyze the different performances of Bitcoin and gold under the impacts of three different uncertainties, namely global economic policy uncertainty (GEPU), US stock market volatility index (VIX) and the CBOE crude oil ETF volatility index (OVX). The results indicate that faced with shocks of different uncertainties, Bitcoin is unable to serve as a safe-haven, while gold can hedge against uncertainties to varying degrees. Moreover, the three types of uncertainties have asymmetric impacts on the prices of Bitcoin and gold respectively. The decrease of uncertainties has a greater impact on Bitcoin price than the increase, while the increase of uncertainties has a greater impact on gold price than the decrease. It suggests that investors are cautious and optimistic about Bitcoin, and gold remains unanimously recognized as the traditional safe-haven.     

Is gold a hedge against inflation? A wavelet time-scale perspective

Among the many presumed characteristics of gold, the ability to act as an enduring store of value is frequently noted. In this paper, the ability of gold to dynamically hedge against inflation is examined for various holding periods using the continuous wavelet transformation. Gold is first established as both a short- and long-term hedge against realized inflation for a number of developed economies. Dynamic analysis demonstrates that these hedging properties are not limited to a single historical cohort. Next, gold is shown to comove with unexpected inflation across all countries examined, albeit with some variation in the direction of the relationship. Finally, the capacity of both gold futures and gold stocks to act as a hedge against inflation is demonstrated.     

Does gold offer a better protection against losses in sovereign debt bonds than other metals?

It is a commonly held view that gold protects investors’ wealth in the event of negative economic conditions. In this study, we test whether other metals offer similar or better investment opportunities in periods of market turmoil. Using a sample of 13 sovereign bonds, we show that other precious metals, palladium in particular, offer investors greater compensation for their bond market losses than gold. We also find that industrial metals, especially copper, tend to outperform gold and other precious metals as hedging vehicles and safe haven assets against losses in sovereign bonds. However, the outcome of the hedge and safe haven properties is not always consistent across the different bonds. Finally, our analysis suggests that copper is the best performing metal in the period immediately after negative bond price shocks.     

Does sustainable investing reduce portfolio risk? A multilevel analysis

This study complements and extends prior research on the risk mitigation role of sustainable investing. We use a continuous measure of funds' sustainability traits, rather than a categorical approach, and assess impact on risk directly rather than by looking at fund performance in up versus down markets. We find that sustainable investing plays a significant role in mitigating total, systematic, and idiosyncratic risk of equity funds, even after controlling for other fund characteristics. Further evidence indicates that the explanation for the risk reduction role of sustainable funds largely runs through traits of the firms held in the funds.     

Do Islamic stock indices perform better than conventional counterparts? An empirical investigation of sectoral efficiency

Literature is rife with studies on efficiency of stock markets and financial performance aspects. One such aspect is the measurement of sectoral efficiency amongst stock markets. While there are several studies analysing sectorial efficiency, there is no study on the efficiency of Islamic sector indexes. The rise of Islamic indices has raised the question and multiple studies have been undertaken in exploring and validating the better performance from a risk return framework for the Islamic indices. This study attempts to pioneer in this niche area by conducting a comparative analysis of 10 sectoral global indices for both conventional and Islamic counterpart spanning over 18 years. The sample time period runs from 1 January 1996 until 31 December 2014. To further validate our study, we have divided our data into four major time periods, to factor in different phases the world markets have gone through in the sample period, i.e. 1996–2000; 2001–2002; 2003–2006 and 2006 to 2014. The methodology selected in understanding the efficiency of these sectoral stock indices is the multifractal de-trended fluctuation analysis (MFDFA). Our analysis reveals that in the shorter horizon, efficiency tends to follow a similar pattern amongst the conventional and Islamic counterpart. Furthermore, Islamic sectoral indices generally tend to exhibit a higher efficiency regime across the last decade. Overall, Islamic index seems to have stayed attractive and resilient, allowing conformity with the weak form efficient market hypothesis.     

Is gold a safe haven or a hedge for the US dollar? Implications for risk management

We assess the role of gold as a safe haven or hedge against the US dollar (USD) using copulas to characterize average and extreme market dependence between gold and the USD. For a wide set of currencies, our empirical evidence revealed (1) positive and significant average dependence between gold and USD depreciation, consistent with the fact that gold can act as hedge against USD rate movements, and (2) symmetric tail dependence between gold and USD exchange rates, indicating that gold can act as an effective safe haven against extreme USD rate movements. We evaluate the implications for mixed gold-currency portfolios, finding evidence of diversification benefits and downside risk reduction that confirms the usefulness of gold in currency portfolio risk management.     

Is the Organisation for Economic Co-operation and Development Ready for China?

Abstract:

The re-emergence of China as a global economic power has intensified calls for the urgent reform of Western-dominated international organizations. We evaluate efforts by the Organisation for Economic Co-operation and Development (OECD) to adapt to the challenge of China. From the first decade of the 2000s, the OECD has undertaken reforms to boost its significance as a key policy actor in the global economy. Part of this effort involves bringing China closer to the organization. To date, only limited progress has been made. We set out three bold policy reforms the OECD could implement that would deepen the OECD’s relationship with China as well as with other emerging economies.     

Is stochastic volatility relevant for dynamic portfolio choice under ambiguity?

Literature on dynamic portfolio choice has been finding that volatility risk has low impact on portfolio choice. For example, using long-run US data, Chacko and Viceira [2005. “Dynamic Consumption and Portfolio Choice with Stochastic Volatility in Incomplete Markets.” The Review of Financial Studies 18 (4): 1369–1402] found that intertemporal hedging demand (required by investors for protection against adverse changes in volatility) is empirically small even for highly risk-averse investors. We want to assess if this continues to be true in the presence of ambiguity. Adopting robust control and perturbation theory techniques, we study the problem of a long-horizon investor with recursive preferences that faces ambiguity about the stochastic processes that generate the investment opportunity set. We find that ambiguity impacts portfolio choice, with the relevant channel being the return process. Ambiguity about the volatility process is only relevant if, through a specific correlation structure, it also induces ambiguity about the return process. Using the same long-run US data, we find that ambiguity about the return process may be empirically relevant, much more than ambiguity about the volatility process. Anyway, intertemporal hedging demand is still very low: investors are essentially focused on the short-term risk–return characteristics of the risky asset.     

Is there a J-curve for Azerbaijan? New evidence from industry-level analysis

This paper estimates the J-curve for Azerbaijan using quarterly industry-level data over the 2000–2009 period. Empirical results show that in 3 of the 10 strategic industries there is strong evidence for the fulfilment of the Marshall–Lerner condition, as the trade balance improves in the long run in reaction to a currency devaluation. In most industries the J-curve pattern is observed in the short run. All 10 cases exhibit long-run cointegration and are stable according to the CUSUM and CUSUMSQ stability tests. These findings are largely consistent with the existing literature on the Azerbaijani J-curve and carry important policy implications.     

Are gold,USD, and Bitcoin hedge or safe haven against stock? The implication for risk management

This study investigates whether gold, USD, and Bitcoin are hedge and safe haven assets against stock and if they are useful in diversifying downside risk for international stock markets. We propose a combined GO-GARCH-EVT-copula approach to examine the hedge and safe haven properties of gold, USD, and Bitcoin. We then examine the attractiveness of these assets in reducing stock portfolio risk by using downside risk measures estimated by the proposed approach and other competing models. We also evaluate the relative performance of the proposed model in reducing downside risk with the competing models. The findings of the study indicate that the USD is the most valuable hedge and safe haven asset closely followed by gold, while Bitcoin is the least valuable. It is also observed that the proposed combined approach performs best in reducing the portfolio downside risk. The findings of this study are of significance for portfolio managers and individual investors who wish to protect the portfolio value during market turmoil.     

Science and proven experience: a Swedish variety of evidence-based medicine and a way to better risk analysis?

A key question for evidence-based medicine (EBM) is how best to model the way in which EBM should ‘[integrate] individual clinical expertise and the best external evidence’. We argue that the formulations and models available in the literature today are modest variations on a common theme and face very similar problems when it comes to risk analysis, which is here understood as a decision procedure comprising a factual assessment of risk, the risk assessment, and the decision what to do based on this assessment, the risk management. Both the early and updated models of evidence-based clinical decisions presented in the writings of Haynes, Devereaux and Guyatt assume that EBM consists of, among other things, evidence from clinical research together with information about patients’ values and clinical expertise. On this A-view, EBM describes all that goes on in a specific justifiable medical decision. There is, however, an alternative interpretation of EBM, the B-view, in which EBM describes just one component of the decision situation (a component usually based on evidence from clinical research) and in which, together with other types of evidence, EBM leads to a justifiable clincial decision but does not describe the decision itself. This B-view is inspired by a 100-years older version of EBM, a Swedish standard requiring medical decision-making, professional risk-taking and practice to be in accordance with ‘science and proven experience’ (VBE). In the paper, we outline how the Swedish concept leads to an improved understanding of the way in which scientific evidence and clinical experience can and cannot be integrated in light of EBM. How scientific evidence and clinical experience is integrated influences both the way we do risk assessment and risk management. In addition, the paper sketches the as yet unexplored historical background to VBE and EBM.     

Is fiscal consolidation self-defeating? A panel-VAR analysis for the Euro area countries

This paper studies the effects of fiscal consolidation on the debt-to-GDP ratio of 11 Euro area countries over the period 2000Q1-2012Q1. Using a quarterly Panel VAR allows us to trace out the dynamics of the debt-to-GDP ratio following a fiscal shock and to disentangle the main channels through which fiscal consolidation affects the debt ratio. We define a fiscal consolidation episode as self-defeating if the level of the debt-to-GDP ratio does not decrease compared to the pre-shock level. Our main finding is that when consolidation is implemented via a cut in government primary spending, the debt ratio, after an initial increase, falls to below its pre-shock level. When instead the consolidation is implemented via an increase in government revenues, the initial increase in the debt ratio is stronger and, eventually, the debt ratio reverts to its pre-shock level, resulting in what we call self-defeating consolidation.     

Is There a Case for Industrial Policy? A Critical Survey

What are the underlying rationales for industrial policy? Doesempirical evidence support the use of industrial policy forcorrecting market failures that plague the process of industrialization?This article addresses these questions through a critical surveyof the analytical literature on industrial policy. It also reviewssome recent industry successes and argues that public interventionshave played only a limited role. Moreover, the recent ascendanceand dominance of international production networks in the sectorsin which developing countries once had considerable successimplies a further limitation on the potential role of industrialpolicies as traditionally understood. Overall, there appearsto be little empirical support for an activist government policyeven though market failures exist that can, in principle, justifythe use of industrial policy.      

Is gold the best hedge and a safe haven under changing stock market volatility?

We evaluate the role of gold and other precious metals relative to volatility (Volatility Index (VIX)) as a hedge (negatively correlated with stocks) and safe haven (negatively correlated with stocks in extreme stock market declines) using data from the US stock market. Using daily data from November 1995 to November 2010, we find that gold, unlike other precious metals, serves as a hedge and a weak safe haven for US stock market. However, we find that VIX serves as a very strong hedge and a strong safe haven during our sample period. We also find that in periods of extremely low or high volatility, gold does not have a negative correlation with the US stock market. Our results show that VIX is a superior hedging tool and serves as a better safe haven than gold during our sample period. We highlight the practical significance of our results for financial market participants by conducting a portfolio analysis.     

Is gold a safe haven against equity market investment in emerging and developing countries?

The hedge and safe haven properties of gold in advanced economies’ financial markets are well documented in the literature. Studies of how this issue relates to emerging markets and developing countries are, however, very limited. This paper aims to fill this gap by empirically analyzing the hedge and safe haven properties of gold against equity market investment for a large group of emerging and developing countries from the perspective of both domestic and foreign investors. We also check whether our findings differ in the post-global crisis period. Our results show that for domestic investors, gold is both a hedge and a safe haven in most of these countries. This result also holds in the post-2008 crisis period. In addition, when falls in equity markets become more severe, gold acts as a safe haven in a larger set of countries for both domestic and foreign investors.     

Health status and portfolio choice: Is their relationship economically relevant?

Recent empirical work on individual portfolio choice focuses on the role of the individual's health in making financial decisions. The key idea is that, through precautionary saving or reducing investors' time horizon, health issues make people choose safer financial portfolios. This paper questions the empirical relevance of the link between health and portfolio choice, measured as stockownership and overall fraction of risky securities held. We handle with caution the findings from previous papers and ask whether data from the first wave of the Survey of Health, Aging and Retirement in Europe (SHARE) are able to clarify some of our doubts. We find that only poor self-reported health negatively impacts the portfolio choice, while other health measures (chronic conditions, limitations in daily activities of life, mental health) are irrelevant for investment decisions.     

Is Germany a model for managers?

Most American managers have a hard time making sense of Germany. The country has a fraction of the resources and less than one-third the population of the United States. Labor costs are substantially higher, paid vacations are at least three times as long, and strong unions are deeply involved at all levels of business, from the local plant to the corporate boardroom. Yet German companies manage to produce internationally competitive products in key manufacturing sectors, making Germany the greatest competitive threat to the United States after Japan. The seemingly paradoxical nature of the German economy typically evokes one of two diametrically opposed responses. The first is to celebrate the German economy as a "model" worth emulating--indeed, as the answer to declining U.S. competitiveness. The alternative, more skeptical response is to question Germany's staying power in a new, more competitive global economy. According to Kirsten Wever and Christopher Allen, the problem with both points of view is that they miss the forest for the trees. Observers are so preoccupied with praising--or blaming--individual components of the German economy that they fail to see the dynamic logic that ties these components together into a coherent system. In their review of recent research on the German business system, Wever and Allen argue that managers can learn an important lesson from Germany. In the global economy, competition isn't just between companies but between entire socioeconomic systems. Germany's ability to design a cohesive economic and social system that adapts continuously to changing requirements goes a long way toward explaining that country's competitive success.     

Is cross-listing a panacea for improving earnings quality? The case of H- and B-share firms in China

This study examines whether cross-listed Chinese H- and B-share firms exhibit higher earnings quality relative to non-cross-listed A-share firms based on seven accounting- and market-based earnings quality attributes, including accrual quality, persistence, predictability, smoothness, conservatism, timeliness and value relevance. We find that earnings quality does not differ between cross-listed and non-cross listed firms in terms of accrual quality, timeliness and value relevance, and that H- and B-share firms report earnings with lower quality in terms of persistence and predictability. We also find that the B-firms report smoother earnings, while the H-firms report more conservative earnings. The results of a battery of cross-sectional, endogeneity and sensitivity analyses either confirm our primary findings of no earnings quality difference or reveal lower earnings quality for cross-listed firms than for non-cross-listed firms. Considering that cross-listing in China is primarily driven by government decisions, our findings suggest that, without proper incentives, cross-listing is not likely to be a panacea for higher quality financial reporting.
