SMART : towards spatial internet marketplaces

Abel, David J.; Gaede, Volker; Taylor, Kerry L.; Zhou, … - 1997

Spatial Internet Marketplaces are attractive as a mechanism to enable spatial applications to be built drawing on remote services for supply of data and for data manipulation. They differ from the usual distributed systems by treating the services as published by providers on the Internet and...

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...

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...

Stationary equilibria in discounted stochastic games with weakly interacting players

Horst, Ulrich - 2002

We give sufficient conditions for a non-zero sum discounted stochastic game with compact and convex action spaces and with norm-continuous transition probabilities, but with possibly unbounded state space to have a N ash equilibrium in homogeneous Markov strategies that depends in a Lipsehitz...

Benchmarking spatial joins à la carte

Günther, Oliver; Oria, Vincent; Picouet, Philippe; … - 1997

Spatial joins are join operations that involve spatial data types and operators. Spatial access methods are often used to speed up the computation of spatial joins. This paper addresses the issue of benchmarking spatial join operations. For this purpose, we first present a WWW-based tool to...
