Covariate Measurement Error in Quadratic Regression.
Kuha, J.; Temple, J. - Economics Group, Nuffield College, University of Oxford - 1999
We consider quadratic regression models where the explanatory variable is measured with error. The effect of classical measurement error is to flatten the curvature of the estimated function. The effect on the observed turning point depends on the location of the true turning point relative to...

The Unscientific Incompleteness and Bias of Unidirectional Projections (= Regressions): A Questionnaire
Los, Cornelis A - EconWPA - 2004
Why do statisticians (econometricians, economists, financial analysts, etc.) continue to incompletely identify the algebraic/geometric structure of the multi-variate data series they profess to analyze, and instead continue to publish the results of incomplete, prejudiced and biased...

A Regime Switching Long Memory Model for Electricity Prices
Haldrup, Niels - 2008
In this paper we develop a regime switching model which can generate long memory (fractional integration) in each of the regime states. This property is relevant in a number of cases. For instance, the deregulated market for electricity power in the Nordic countries is characterized by...

Analysis of Financial Correlation Matrix Using Random Matrix Theory
Li, Liang-Xin - 2008
. Compared with the analytical random matrix theory results, we found that a small part about 11%of eigenvalues are out of the … range of random matrix theory results and that the distribution of the components of the eigenvector corresponding to the … largest eigenvalue is evidently different from that of random matrix theory. These results demonstrate that chinese stock …

Pension Information, Human Capital, and Firm Valuation
Li, Yan - 2008
We re-evaluate the evidence on the association between pension information and firm valuation by considering alternate theoretical constructs that can be captured in pension information. Economically, pension plans, especially defined benefit plans, but also defined contribution plans, are more...

Price Ceilings as Focal Points for Tacit Collusion : Evidence from Credit Cards
Knittel, Christopher R. - 2008
We test whether a non-binding price ceiling may serve as a focal point for tacit collusion, using data from the credit card market during the 1980s. In our sample, most credit card issuers face a state-level interest rate ceiling, and well over half match their ceiling. We develop an empirical...

Detecting Misspecifications in Autoregressive Conditional Duration Models
Hong, Yongmiao - 2007
We propose a new class of specification tests for Autoregressive Conditional Duration (ACD) models. Both linear and nonlinear ACD models are covered, and standardized innovations can have time-varying conditional dispersion and higher order conditional moments of unknown form. No specific...
