Since the banking crisis the market for volatility exchange‐traded products has developed rapidly as it opens to clients beyond the large institutional investor pool. Speculation is driven by increasingly complex leveraged and inverse exposures including those that attempt to trade on significant roll costs in volatility futures curves. Longer‐term investors use these products for the purposes of equity diversification, driven by fears of an ongoing Eurozone crisis. We survey the burgeoning academic literature in this area and present a comprehensive and up‐to‐date comparison of the market and statistical characteristics of European and US exchange‐traded volatility products. 相似文献

The estimation of medium-term market risk dictated by limited data availability, is a challenging issue of concern amongst academics and practitioners. This paper addresses the issue by exploiting the concepts of volatility and quantile scaling in order to determine the best method for extrapolating medium-term risk forecasts from high frequency data. Additionally, market risk model selection is investigated for a new dataset on ocean tanker freight rates, which refer to the income of the capital good — tanker vessels. Certain idiosyncrasies inherent in the very competitive shipping freight rate markets, such as excessive volatility, cyclicality of returns and the medium-term investment horizons – found in few other markets – make these issues challenging. Findings indicate that medium-term risk exposures can be estimated accurately by using an empirical scaling law which outperforms the conventional scaling laws of the square and tail index root of time. Regarding the market risk model selection for short-term investment horizons, findings contradict most studies on conventional financial assets: interestingly, freight rate market risk quantification favors simpler specifications, such as the GARCH and the historical simulation models. 相似文献

Further insights on the relationship between SP500, VIX and volume: a new asymmetric causality test1
Catherine Kyrtsou Dimitris Kugiumtzis Angeliki Papana 《European Journal of Finance》2019,25(15):1402-1419
In the aim to explore the complex relationships between S&P500, VIX and volume we introduce a Granger causality test using the nonlinear statistic of Asymmetric Partial Transfer Entropy (APTE). Through a simulation exercise, it arises that the APTE offers precise information on the nature of the connectivity. Our empirical findings concretize the information flow that links volume, S&P500 and VIX, and merge the leverage effect and the asymmetric stock return-volume relationship into a unified framework of analysis. More specifically, when we condition on the tails, the detected causal channel provides empirical validation of the noise trading contribution to large swings in financial markets, because of the increase of trading volume and the subsequent worsening ability of market prices to adjust to new information. 相似文献

The current regulatory framework in the European NGA market provides the basic principles for the gradual migration from service-based competition over the legacy copper access networks to facilities-based competition over fiber-based Next Generation Access (NGA) networks. This paper initially reviews the related literature and shows that: (i) an unbundling policy that boosts entry by alternative operators promotes service-based competition but provides operators with disincentives to invest in network upgrade; (ii) there is no consensus about the optimal regulatory policy that promotes competition and encourages investments in NGA networks; and (iii) the reviewed research articles are not consistent with the current regulatory framework in the European NGA market in terms of both the evolution of the regulatory goals over time and the recommended regulatory settings. This paper aims to propose a novel approach in order to effectively meet the current regulatory goals using the recommended settings. It is shown that the proposed approach, which is based on the basic principles governing a Credit Default Swap (CDS), provides an effective migration path towards facilities-based competition over NGA networks. 相似文献

The present paper reports results from a comparative analysis of the effectiveness of regional policy schemes in areas of Scotland and Greece. Discretionary schemes are of a lower gross cost per job than automatic ones in both countries. Additionality was found to be very high among all schemes in both countries. Results indicate that future policy design should be decentralised and highly adapted to local conditions. In the case of Greece, the dominant top-bottom style of policy making acts as major constraints in the adoption of more decentralised policy design and delivery mechanisms. In the case of Scotland such a task is easier to accomplish. 相似文献

In this paper, we assess the movements of euro area sovereign bond yield spreads vis-à-vis the German Bund as processes specified across different levels of volatility and subject to movements in asset prices and economic conditions. The determinants we use are grouped into domestic and euro-area aggregates, thus allowing us to derive results on their relative explanatory power and compare them across time and the spectrum of countries. We find that volatility influences the deterministic processes of the euro area sovereign spreads and that identical determinants have effects on spreads that vary considerably across countries. Furthermore, we find that variables reflecting investment confidence conditions and perceptions for the upcoming economic activity are significant determinants and their significance remains, to a large extent, even when controlling for fiscal variables. 相似文献

We investigate the relationship of the market pricing of sovereign risk to default, through credit default swap (CDS) spreads for 16 Eurozone countries during 2008q1–2013q3. We take into account, through appropriate non-linear generalized method of moments (GMM) estimations the endogeneity problem. We focus on ‘fiscal space’ (DEBT or FISCAL), and the downgrade announcements (DOWN). We find DEBT (FISCAL) to have significant (insignificant) effects on the CDS concave function, as well as, DOWN in a linear one. It has also been confirmed significant pricing discrimination between South and West Euro Area Periphery (SWEAP) and the core Eurozone, highlighting asymmetries discovered either by the respective size of estimated DEBT coefficients or by the significant effects of DOWN that have only on CDS of SWEAP countries. The current account balance or the inflation rate, as well as, relevant interaction terms seem not to affect the spreads of the EMU. These findings, together with the estimated structural change on CDS pattern in early 2011, coinciding with significant either the DOWN in the pre-crisis period (2008–2010) or the DEBT in the post-crisis one (2011–2013) on the CDS, seem to be consistent with self-fulfilling crises literature and the inherent vulnerability of EMU, on other words, the ‘fragility hypothesis of the Eurozone’. 相似文献

This article presents estimates of labour values and prices of production following two approaches: the first is based on the classical and Marxian theory of value and distribution; the second on the so-called ‘new solution’ to the ‘transformation problem’ and its variant, the Temporary Single-System Interpretation (TSSI). The major advantage of the latter approach is its simplicity, along with the relatively low data requirements. Our empirical findings from the economies of China, Japan and South Korea suggest that both approaches give estimates of labour values and prices of production which are extremely close to each other as well as to actual market prices. On further examination, however, we conclude that our empirical findings are absolutely consistent with the theoretical requirements of the classical approach and contradict those of the TSSI. 相似文献
