Fractional cointegration and tests of present value models

Caporale, Guglielmo Maria; Gil-Alaña, Luis A. - 2000

This paper tests the validity of Present Value (PV) models of stock prices by employing a two-step strategy for testing the null hypothesis of no cointegration against alternatives which are fractionally cointegrated. Monte Carlo simulations are conducted to evaluate the power and size...

Nonparametric specification testing for continuous-time models with application to spot interest rates

Hong, Yongmiao; Li, Haitao - 2002

We propose two nonparametric transition density-based speciÞcation tests for continuous-time diffusion models. In contrast to marginal density as used in the literature, transition density can capture the full dynamics of a diffusion process, and in particular, can distinguish processes with...

Flexible stochastic volatility structures for high frequency financial data

Feldmann, David; Härdle, Wolfgang; Hafner, Christian M.; … - 1998

Stochastic Volatility (SV) models are widely used in financial applications. To decide whether standard parametric restrictions are justified for a given dataset, a statistical test is required. In this paper, we develop such a test based on the linear state space representation. We provide a...

Simultaneous over- and underconfidence : evidence from experimental asset markets

Maciejovsky, Boris; Kirchler, Erich - 2001

In this paper individual overconfidence within the context of an experimental asset market is investigated. Overall, 72 participants traded one risky asset on six markets of 12 participants each. The results indicate that individuals were not generally overconfident. Moreover, overconfidence was...

Dumb software agents on an experimental asset market

Grossklags, Jens; Schmidt, Carsten; Siegel, Jonathan - 2000

We have analyzed the impact of agents and their trading strategies on an experimental electronic market. Therefore, we added an XML-interface to an existing electronic market and implemented artificial agents which acted as elements of disturbance in the trading process. These artificial traders...

Framing effects on asset markets : an experimental analysis

Kirchler, Erich; Maciejovsky, Boris; Weber, Martin - 2001

In this paper we investigate four hypotheses which are inconsistent with expected utility theory, but may well be … explained by prospect theory. It deals with framing, the non-linearity of subjective probabilities, the disposition effect, and …) found little correspondence between different experimental risk elicitation methods. -- Prospect Theory ; Framing …

How accurate do markets predict the outcome of an event? : the Euro 2000 soccer championships experiment

Schmidt, Carsten; Werwatz, Axel - 2002 - Rev.

For the Euro 2000 Soccer Championships an experimental asset market was condueted, with traders buying and selling contracts on the winners of individual matches. Market-generated probabilities are compared to professional bet quotas, and factors that are responsible for the quality of the...

Modeling the interdependence of volatility and inter-transaction duration processes

Grammig, Joachim; Wellner, Marc - 1999

In this paper we motivate, specify and estimate a model in which the intra-day volatilty process affects the inter-transaction duration process and vice versa. In order to solve the estimation problems implied by this interdependent formulation, we first propose a GMM estimation procedure for...
