Is gold a hedge and safe haven for stock market?

The paper aims to examine the hedge and safe haven properties of gold relative to Dow Jones stock industry indices using quantile-GARCH approach. Splitting the sample period into two sub-periods, our results show that the hedge and safe haven properties of gold have a changing nature. In a whole period (1980–2017), gold is not a hedge for Oil&Gas, Basic materials and Utilities; gold is a safe haven for almost all sectors except Technology. While in sub-period I (1980–1995) gold is not a hedge for Oil&Gas but a strong safe haven for all sectors. In sub-period II (1996–2017) gold is not a hedge for Oil&Gas, Basic materials and Utilities, also not a safe haven for Oil&Gas, Basic materials, Utilities, Telecom and Technology.     

Eurozone crisis and BRIICKS stock markets: Contagion or market interdependence?

This paper examines the financial contagion in an emerging market setting by investigating the contagion effects of GIPSI (Greece, Ireland, Portugal, Spain and Italy), USA, UK and Japan markets on BRIICKS (Brazil, Russia, India, Indonesia, China, South Korea and South Africa) stock markets. During Euro-zone crisis period (October 19, 2009–January 31, 2012), the empirical results indicate that among GIPSI countries, Ireland, Italy and Spain appear to be most contagious for BRIICKS markets compared to Greece. The study reports that Brazil, India, Russia, China and South Africa are strongly hit by the contagion shock during the Eurozone crisis period. However, Indonesia and South Korea report only interdependence and not contagion. From policy perspective, the findings provide useful implications for possible decoupling strategies to insulate the economy from contagious effects. For multilateral organizations like International Monetary Fund (IMF) and World Bank, the study will provide an important direction in undertaking coordinated rescue measures for the vulnerable as well as contagious countries.     

Is the cryptocurrency market a hedge against stock market risk? A Wavelet and GARCH approach

This study analyses six major cryptocurrencies and four global stock markets to explore the role of cryptocurrencies as a hedge, safe haven, and diversifier in stock markets. The study employs ADCC-GARCH and Wavelet Coherence Technique, using daily data from 4 January 2017 to 28 February 2023. The study has found that stock returns and unstable cryptocurrency returns have high volatility persistence in the long run. Besides, while unstable digital currencies (Bitcoin, Ethereum, Binance Coin, and Dogecoin) serve as a hedge during stable economic periods, they have not been a hedge during economic turmoil in the stock markets. Conversely, stablecoins (Tether and USD Coin) have been shown to have acted as a hedge during normal economic times and have offered a safe haven during economic downturns. Except for Tether, all cryptocurrencies' diversification capacity is time-varying. In stable economic conditions, they serve as diversifiers, but during turmoil, they do not. However, Tether serves as a diversifier regardless of the financial situation. Finally, the present investigation is expected to offer crucial information on hedge, safe haven and diversification for quasi-investors.     

The role of economics in global management of whales: re-forming or re-founding IWC?

The global management of whale species, identified as an economic mixed good, is addressed by means of economic theory of bargaining and institution making. I will analyse (i) why it is important to take into account explicitly both (consumptive) use and non-use values within international conventions on global mixed goods; (ii) the role and nature of institutions dealing with global issues; (iii) the role of bargaining between conflicting interests as a focal feature of the institution-making process; and, (iv) the role of economic thinking in international conventions. Co-operative and non co-operative solutions are discussed, and instruments aimed at achieving co-operative bargaining, analysed. The study has both positive and normative implications, with insights on social welfare enhancing institutional reforms. Although the study is broad yet special focus is given to the International Whaling Commission (IWC). This paper concludes that we should make economic theory operational within the realm of global institutions. On the basis of the bargaining model, the conclusion is that IWC should necessarily be re-founded or at least re-formed, changing the convention from ‘whaling’ to a ‘whale’. It is suggested that the possibility of introducing compensatory side payments into the bargaining arena in order to increase social welfare and enforceability with respect to a ‘ban’ scenario be investigated. Ethical implications of monetary compensations are considered in parallel with economic efficiency. The limits and potentialities of economics and economic instruments are also tested globally with respect to the whale and other environmental issues.     

Do speculative bubbles migrate in the Chinese stock market?

In this paper, a duration dependence test for speculative bubbles in the Chinese stock market is developed. It is found that bubbles in the aggregate stock price existed before the split share reform. After the reform, we observe the phenomenon of bubble migration across industries. In particular, bubbles migrate from the telecommunications industry to the health care industry. Moreover, we find that monetary policy used to have a significant impact on the bubble size before the reform but the impact diminished after the reform.

     

Do political connections decrease the accuracy of stock analysts' recommendations in the Chinese stock market?

This paper studies the association between the accuracy of analysts' recommendations and political connections in the Chinese stock market. As most brokerage firms in China are state-owned, it raises concerns about conflicts of interest among their employed analysts issuing recommendations for Chinese state-owned enterprises. Based on 8469 analysts' recommendations with different ratings for both state-owned and non-state-owned enterprises from 74 brokerage firms, we document that analysts' recommendations are less accurate for Chinese state-owned enterprises, which supports the hypothesis that conflicts of interest create recommendation biases. Political connections encourage analysts to be more optimistic on SOEs and even to generate misleading “Buy” and “Hold” recommendations. Our results demonstrate the existence of an optimism bias among politically connected analysts on state-owned enterprises in China.     

Bitcoin for energy commodities before and after the December 2013 crash: diversifier,hedge or safe haven?

We study the relationship between Bitcoin and commodities by assessing the ability of Bitcoin to act as a diversifier, hedge, or safe haven against daily movements in commodities in general, and energy commodities in particular. We focus on energy commodities because energy, in the form of electricity, is an essential input in the Bitcoin production. For the entire period, results show that Bitcoin is a strong hedge and a safe-haven against movements in both commodity indices. We further examine whether that ability is also present for non-energy commodities and our analysis show insignificant results when energy commodities are excluded from the general commodity index. We also account for the December 2013 Bitcoin price crash and our results reveal that Bitcoin hedge and safe-haven properties against commodities and energy commodities are only present in the pre-crash period, whereas in the post-crash period Bitcoin is no more than a diversifier. In addition to uncovering the time-varying role of Bitcoin, we highlight the dissimilarity in the dynamic correlations between the extreme downward and extreme upward movements.     

Is gold a weak or strong hedge and safe haven against stocks? Robust evidences from three major gold-consuming countries

In this article, we test nexus between gold and stocks for the three major gold consumers by using the range of methodologies. First, we assess if there is any time-varying correlation between the two assets. We fail to find any significant time-varying correlation between gold and stock returns in India and the United States. Second, we attempted to investigate the safe-haven property of gold by analysing the decile-wise conditional correlation between stock returns and gold returns at different deciles of stock returns. Third, in order to test the robustness of the results drawn from the decile-wise correlation, we employ wavelet coherence in continuous wavelet framework to test the time and frequency varying nexus between the pair of assets. The range of methodologies employed seems to indicate the weak hedge and safe haven-property of gold for stocks.     

Islamic financial markets and global crises: Contagion or decoupling?

This paper investigates the contagion effects of the global financial crisis (GFC) and Eurozone sovereign debt crisis (ESDC) on Islamic equity and bond markets. Using a sample of Islamic stock indices from various developed and emerging markets and the global Islamic stock and bond (sukuk) indices, we explore asymmetric conditional correlation dynamics across stable and crisis periods and across the two crises. The results fail to provide strong contagion evidence between conventional and Islamic equity and bond indices, supporting the decoupling hypothesis of the Islamic securities. Our findings imply that Islamic equities and bonds may provide a cushion against risk and instability, particularly in periods of turmoil. The small number of contagion cases mostly relates to the ESDC and developed Islamic stock indices. The findings also show that the Islamic emerging stock indices in the BRICS provide the most effective international portfolio diversification benefits compared to the Islamic developed indices.     

A national or local phenomenon? A comparison of the US and the Chinese housing markets

This article investigates the common movements of house prices across cities as well as the macroeconomic underpinnings of the comovements in the US and China. Our empirical results indicate more differences than similarities between the US and the Chinese housing markets. The results from a Bayesian dynamic latent factor model indicate that the fluctuations of house prices across cities in the US are more a national phenomenon, while the dynamics of house prices across cities in China are mainly driven by the city-specific component. We further use VAR models to compare the roles of the underlying determinants in these two housing markets. The results show that the roles of monetary policy shocks and aggregate fluctuations in driving the common movements of house prices across cities differ substantially between the US and China at both short and long horizons.     

How does leverage in stock market influence the margin of stock index futures?

In this article, we propose a margin-setting model under the assumption of extreme stock price changes. Specifically, extreme stock price changes are caused by the positive feedback effect of leverage and market impact. By introducing these factors into the futures price changes through a cost-of-carry model for setting the margin of stock index futures, we find that leverage and market impact in stock market are positively correlated with the margin.     

Does crude oil move stock markets in Europe? A sector investigation

The aim of this article is to investigate the responses of European sector stock markets to oil price changes. We use linear and asymmetric models and study the association of oil and stock prices. Our findings suggest that the strength of this association varies greatly across sectors. Moreover, for some sectors we find strong evidence of asymmetry in the reaction of stock returns to changes in the price of oil.     

A core–periphery framework in stock markets of the euro zone

The introduction of the euro was expected to have an effect not only on real convergence of economies but also on stock markets. This research compares the dynamics and synchronization of stock market regimes in European markets before and after the euro launch. Countries of the euro zone are found to have different dynamics with regard to switching between bull and bear markets, but the differences become less pronounced after the introduction of the single currency, increasing the overall level of stock market synchronization. Nevertheless, Austria and Portugal reduced the level of regime synchronization with other stock markets. The results delineate a framework of core–periphery stock markets, i.e., a large group of stock markets that share the same market regime, with some others on the periphery characterized by distinctive behavior.     

The impact of monetary policy on financial markets in small open economies: More or less effective during the global financial crisis?

This paper estimates the impact of monetary policy on exchange rates and stock prices of eight small open economies: Australia, Canada, the Republic of Korea, New Zealand, the United Kingdom, Indonesia, Malaysia, and Thailand. On average across these countries in the full sample, a one percentage point surprise rise in official interest rates leads to a 1% appreciation of the exchange rate and a 0.5–1% fall in stock prices, with somewhat stronger effects in OECD countries than non-OECD countries (though differences are sometimes not significant). We find little robust evidence of a change in the effect of monetary policy surprises during the recent financial crisis.     

Is the stock market sticker shocked? A study of market response to recent CAFE regulations in the US

In response to increasing environmental concerns, to improve energy security and to conserve energy use, the US government has proposed a new round of Corporate Average Fuel Economy (CAFE) standards. Many studies have focused on how the CAFE standard can be met by various automakers that have sales in the US market, and the costs and benefits of the companies meeting the standard. However, the stock markets’ view on the impact of the standard on automakers’ profitability is largely absent. We study the more recent episode of the CAFE regulation in an effort to try to detect the market response using the standard event study method. Our empirical findings suggest that while the stock market had some responses to the regulation, the large-scale and systematic reaction to the regulation is absent. In addition, the market response pattern to the regulation appears to be tied to the individual company’s compliance condition if there is any significant response at all.     

Speculative bubbles or market fundamentals? An investigation of US regional housing markets

This paper investigates the existence of speculative bubbles in the US national and 21 regional housing markets over three decades (1978–2015). A new method for real-time monitoring exuberance in housing markets is proposed. By taking changes in the macroeconomic conditions (such as interest rate, per-capita income, employment, and population growth) into consideration, the new method provides better control for housing market fundamentals and thereby it is expected to significantly reduce the chance of false positive identification. Compared with the method of Phillips et al. (2015a, 2015b), the new approach finds a dramatic reduction in the number of speculative housing markets and shorter bubble episodes in the US. It locates only one bubble episode in the early-to-mid 2000s over the whole sample period in the national housing market. At the regional level, it identifies two periods of speculation: late 1980s and early-to-mid 2000s. The early-to-mid 2000s bubble episode lasts longer and involves 16 metropolitan statistical areas.     

Why should Southern economies stay in the Euro Zone? The role of labor markets

We assume a world of two countries in a fixed exchange rate system. These countries differ in the features of their labor markets. The home country is characterized by a dual labor market, with formal and informal sectors. In the foreign country, a nominal wage rigidity exists. In this context, the situation of the labor markets in each country is not optimal owing to a misallocation of workers between sectors in the domestic economy and unemployment in the foreign economy. We show that a devaluation of domestic currency implies a fall in production in each country and deterioration of labor markets in both countries.     

Momentum in global equity markets in times of troubles: Does the economic state matter?

This paper investigates the profitability of momentum-based trading strategies pursued during the most recent economic downturns in global equity markets. In contrast to previous studies, it reveals that such strategies generated statistically significant negative returns during the most recent recessions. These “momentum crashes” happen during market reversals following exceptionally large market declines, as occurred in March and April 2009.
