The study examines estimation of parameters of diffusion market models from historical data. The standard definition of implied volatility for these models presents its value as an implicit function of several parameters, including the risk-free interest rate. In reality, the risk free interest...

This study is an empirical implementation of Alghalith's methodology. In doing so, it provides empirical comparative statics results for the hedging agents under simultaneous price and output uncertainty.

Using monthly data from 1994:01 to 2005:03, the results from vector autoregressive models and generalized impulse response analysis indicate that unexpected shocks in industrial production, inflation, term structure, default risk, and the federal funds rate have virtually no statistically...

This paper introduces the Flexible Dynamic Conditional Correlation (FDCC) multivariate GARCH model which generalizes the Dynamic Conditional Correlation (DCC) multivariate GARCH model proposed by Engle (2002). The FDCC model relax the assumption of common dynamics among all assets used in the...

Political instability causes jump-risk volatility in domestic risky asset returns. The effects of outcome risk on portfolio decisions are inherently linked to their impact on the conditional moments of the asset return. Although rare events are stochastic and move discontinuously, major events...

This letter uses the Block Maxima Extreme Value approach to quantify catastrophic risk in international equity markets. Risk measures are generated from a set threshold of the distribution of returns that avoids the pitfall of using absolute returns for markets exhibiting diverging levels of...

The theoretical literature on a firm's choice of debt maturity argues that a borrowing firm can signal its value in an asymmetric information setting by borrowing short. This well-known fact is based on Flannery (1986). This note questions the use of debt maturity as a signalling device. It...

This study estimates the order of integration in the volatility process of several exchange rates and stock returns using fractionally integrated semiparametric techniques, namely a local Whittle semiparametric estimator. The results suggest that all series can be well described in terms of I (...

The aim of this study is to assess the effect of claims and expenses on premiums for the UK property-liability insurance industry. A cointegration approach of a multivariate system of equations is applied to disentangle the causal relationships between premiums, claims and expenses. The findings...

The significant role played by beta in various aspects of financial decision-making has forced people from small investors to investment bankers to rethink on beta in the era of globalization with ever changing market conditions. Standing on the edge of a free capital mobile world with...
