The new market for volatility trading

This study analyses the new market for trading volatility; VIX futures. We first use market data to establish the relationship between VIX futures prices and the index itself. We observe that VIX futures and VIX are highly correlated; the term structure of average VIX futures prices is upward sloping, whereas the term structure of VIX futures volatility is downward sloping. To establish a theoretical relationship between VIX futures and VIX, we model the instantaneous variance using a simple square root mean‐reverting process with a stochastic long‐term mean level. Using daily calibrated long‐term mean and VIX, the model gives good predictions of VIX futures prices under normal market situation. These parameter estimates could be used to price VIX options. © 2010 Wiley Periodicals, Inc. Jrl Fut Mark 30:809–833, 2010     

Futures market equilibrium under Knightian uncertainty

This paper examines the effects of Knightian uncertainty on a commodity futures market within the Newbery‐Stiglitz framework. It is shown that Knightian traders act more conservatively. In a partial trade equilibrium, risk aversion and Knightian uncertainty have qualitatively similar effects on the equilibrium price and the equilibrium trading volume. Full‐trade and no‐trade equilibria are likely to prevail when the producer and the speculator incur different Knightian uncertainty. Herein different impacts of risk aversion and Knightian uncertainty are observed. © 2003 Wiley Periodicals, Inc. Jrl Fut Mark 23:701–718, 2003     

Unemployment and relative labor market institutions between trading partners

This paper contributes to the literature that highlights the role of trading partners' institutions for a country's unemployment rate. The objective is to study whether the results established in the minimum wage-setting of Davis (1998) hold when unemployment is driven by search frictions. This paper finds that relative labor market institutions matter for equilibrium unemployment as they generate comparative advantages, but there are two main differences with Davis. With North-North trade, unemployment decreases in the low-regulation country. When South is brought into the picture, low-regulation North is not insulated, and unemployment increases in both developed countries as a result of specialization.     

Calendar trading of Taiwan stock market: A study of holidays on trading detachment and interruptions

We analyze the influence of the Chinese lunar calendar and superstitions on holiday preferences using theories on time and mood to identify investor sentiment. Trading interruptions caused by Thursday holidays negative significantly influence investor sentiment for trust companies and individual investors. Trading detachment derived from cultural holidays in June positive significantly influences investor sentiment for dealers and individual investors. Trust companies and the market exhibit significantly positive sentiments toward winter holidays. The stock exchange indicates negative and positive sentiments toward winter holidays and holidays in January. Cultural holidays and superstition in Taiwan indicate strong support for holiday preferences in Asia.

Stock market trading in the aftermath of an accounting scandal

In this paper, we study the impact of accounting fraud revelation on trading behaviour of investors. Using daily investor account holdings data from the National Stock Depository Limited (NSDL), the largest depository in India, we find that investors directly exposed to accounting fraud cash out almost 10.7 percentage points of their overall portfolio relative to investors not directly exposed. The cashing out is largely restricted to the bad stock. Over the period of a month, however, there is no difference in the trading behaviour of the treated and control investors.
