A new alternative diffusion model for asset price movements is presented. In contrast to the popular approach of Brownian motion it proposes deterministic diffusion for the modelling of stock price movements. These diffusion processes are a new area of physical research and can be created by the...

The standard measures of distress risk ignore the fact that firm defaults are correlated and that some defaults are more likely to occur in bad times. We use risk premium computed from corporate credit spreads to measure a firm’s exposure to systematic variation in default risk. Unlike...

In the 1990s, companies collected billions in premiums from peculiarly structured put options written on their own stock while almost all of these puts expired worthless. Buyers of these options, primarily �nancial intermediaries, lost money as a result. Although these losses might seem...

The September 30, 1978 legislation (P.L. 95-405), which renewed the authority of the CFTC to regulate futures markets, directs the Commission to solicit the advice of the Treasury and the Federal Reserve before authorizing any additional futures contracts that specify delivery of U.S. Government...

The purpose of this paper is to understand how the current financial landscape shaped by the crises and new regulations impacts Investment Banking’s business model. We will focus on quantitative implications, i.e. valuation, modeling and pricing issues, as well as qualitative implications,...

In this paper we examine the effects of media coverage of commodity prices increases and decreases on the price of the commodity and how media coverage in other commodities affects prices. We provide evidence of the relationship between media coverage and its intensity to the price level of...

This paper analyses the intraday co-movements between returns on several commodity markets and on the stock market in the United States over the 1997-2011 period. By exploiting a new high frequency database, we compute various rolling correlations at (i) 1-hour, (ii) 5-minute, (iii) 10-second,...

In a recent article, Ederington (1979) examined the hedging performance of financial futures markets using a portfolio model derived from the hedging theories of Stein (1961) and Johnson (1960). His article concluded that GNMA futures were more effective than T-Bill futures in reducing price...

Despite experiencing rapid growth in their number and size, existing evidence suggests that African stock markets remain highly fragmented, small, illiquid and technologically weak, severely affecting their informational efficiency. Therefore, this study attempts to empirically ascertain whether...

The September 30, 1978 legislation (P.L. 95-405), which renewed the authority of the CFTC to regulate futures markets, directs the Commission to solicit the advice of the Treasury and the Federal Reserve before authorizing any additional futures contracts that specify delivery of U.S. Government...
