The concept of rational performance-chasing equilibrium in recent literature is supported neither by theory nor by empirical evidence. A more accurate model of such market dynamics is based on investor confusion, which is partly driven by some active managers' performance manipulation. Unlike...

The paper examines correlations between daily returns of month-ahead baseload electricity, fuel input and carbon emission allowance (EU-ETS) prices for Great Britain. The perspective of a CCGT plant operator is assumed, producing baseload electricity with natural gas and emission allowances and...

This paper examines the drivers behind revenues of merchant electricity interconnectors and the effect of arbitrage trading over interconnectors on the level and volatility of electricity prices in the connected markets. It sets out a simulation methodology that allows the stochastic and...

This paper estimates the effect of the merchant interconnector between Norway and the Netherlands on the level and residual volatility of hourly day-ahead electricity prices in the two connected markets. The price effects are estimated using single equation ARMA models and the volatility effects...

Rational herd behavior and informationally efficient security prices have long been considered to be mutually exclusive but for exceptional cases. In this paper we describe the conditions on the underlying information structure that are necessary and sufficient for informational herding and...

Empirical evidence suggests that many macroeconomic and financial time-series are subject to occasional structural breaks. In this paper we present analytical results quantifying the effects of such breaks on the correlation between the forecast and the realisation, and on the ability to...

This paper deals with the issues of identification and estimation in the canonical model of contagion advanced in Pesaran and Pick (2007). The model is a two-equation nonlinear simultaneous equations system with endogenous dummy variables; it also represents an extension of univariate threshold...

This paper presents a canonical, econometric model of contagion and investigates the conditions under which contagion can be distinguished from inter-dependence. In a two-country (market) set-up it is shown that for a range of fundamentals the solution is not unique, and for sufficiently large...

The GARCH-t model is widely used to predict volatilty. However, modeling the conditional variance as a linear combination of past squared observations may not be the best approach if the standardized observations are non-Gaussian. A simple modi.cation lets the conditional variance, or its...

This paper is concerned with testing the time series implications of the capital asset pricing model (CAPM) due to Sharpe (1964) and Lintner (1965), when the number of securities, <em>N</em>, is large relative to the time dimension, <em>T</em>, of the return series. Two new tests of CAPM are proposed that exploit...
