The efficient market hypothesis states that the market incorporates all available information to provide an accurate valuation of the asset at any given time. However, most models for forecasting the return or volatility of assets completely disregard the arrival of asset specific news (i.e., news which is directly relevant to the asset). In this paper we propose a simple adaptation to the GARC...
We use experiments to study the efficiency effects for a market as a whole of adding the possibility of forward contracting to a pre-existing spot market. We deal separately with the cases where spot market competition is in quantities and where it is in supply functions. In both cases we compare the effect of adding a contract market with the introduction of an additional competitor, changing ...
In this paper we present a model for the dynamic evolution of the term structure of default-free and defaultable interest rates. The model is set in the Libor market model framework but in contrast to the classical diffusion-driven setup, its dynamics are driven by a time-inhomogeneous Lévy process which allows us to better capture the real-world dynamics of credit spreads. We present necessary...
During the past two decades financial systems world-wide have developed rapidly in terms of size, industry structure, and the range of products and services produced. In Australia the size of the financial system, measured by total assets, has approximately doubled relative to nominal GDP in the past twenty years, while in a number of other countries the growth has been even more dramatic. More...
I Declaration This dissertation is submitted to the University of Bristol in accordance with the requirements of the degree of Master of Science in the Faculty of Engineering. It has not been submitted for any other degree or diploma of any examining body. Except where specifically acknowledged, it is all work of the Author. Labs-Bristol). Some work had been done in the evolution of market mech...
With the rapid development of the Internet, many retailers and individuals nowadays use this technology to engage in direct e-retailing sales. In this article, we investigate the value of demand-forecast information sharing in a manufacturer-e-retailer supply chain. The value of market information depends not only on its accuracy, but also on the e-retailer’s market power and the product’s Web ...
We study the problem of computing equilibrium prices in a Fisher market with linear utilities and linear single-constraint production units. This setting naturally appears in ad pricing where the sum of the lengths of the displayed ads is constrained not to exceed the available ad space. There are three approaches to solve market equilibrium problems: convex programming, auction-based algorithm...
Software vulnerability disclosure has become a critical area of concern for policy-makers. Traditionally, Computer Emergency Response Team (CERT) has been acting as an infomediary between benign identifiers (who report vulnerability information voluntarily) and software users. After verifying a reported vulnerability, the infomediary – CERT – sends out a public “advisory” so that users can safe...
In this paper we study dynamic pricing mechanisms of financial derivatives. A typical model of such pricing mechanism is the so-called g–expectation defined by solutions of a backward stochastic differential equation with g as its generating function. Black-Scholes pricing model is a special linear case of this pricing mechanism. We are mainly concerned with two types of pricing mechanisms in a...
Following the multistage design approach, we propose two asymptotically efficient truthful double auction mechanisms, the BC-LP mechanism and the MBC mechanism, for an exchange market with many buyers and sellers. In this market, each buyer wants to procure a bundle of commodities and each seller supplies one unit of a commodity. Furthermore, various transaction-related costs will be incurred w...
