In this paper, we develop alternative models to price derivative securities when the underlying asset may be subject to jumps. These models allow for two kinds of jumps: scheduled jumps which are caused by information for which the disclosure data is known in advance (e.g. earnings...

We develop here a framework of cross currency arbitrage in the presence of a currency peg. In particular the relationship between interest rate and FX derivatives is analysed in such a framework.

What kind of information do stock prices offer for predicting velocity? This paper develops previous work by Milton Friedman for the US economy and shows that a wealth effect derived from the stock market has negatively influenced the ratio of nominal income to a broad definition of money in a...

Although there has been extensive research on the economic functions of financial exchanges and the properties of prices determined on exchanges, there has been little research on the organizational structure and governance of these exchanges. This article demontrates that the heterogeneity of...

A front page Sunday New York Times article on a potential development of new drugs to cure cancer caused the price of EntreMed (ENMD) stock to rise from 12.063 at the Friday close, to open at 85 and close near 52 on Monday. Trading volume was more than 400 times the normal trading volume, and...

In June 1997, the Nasdaq stock market and the New York Stock Exchange (NYSE) each lowered its minimum price increment on most stocks from eighths to sixteenths. Like other researchers investigating similar events, we find that quoted spreads and effective spreads decline on both markets with the...

Under some minimal assumptions on the price functional, we prove that the prices of the contingent claim are necessarily in some minimal interval.

In this paper we first prove an equilibrium existe theorem for finite dimensional economies with unbounded below consumption sets. We only assume that the individually rational utility set is compact and use the demand approach instead of the standard Negishi's approach. We next compare the...

We present an equilibrium framework in which asset prices, default-free term structure and default premia are determined simultaneously.

We compare the price impact of trades across market structures by examining firms that switch exchanges. When firms are listed on Nasdaq, quoted prices adjust quite slowly to the information contained in order flow. On average, it takes about 5 minutes (or about 6 transactions) for half of the...
