On autoregressive errors in singular systems of equations

Dhrymes (1994, Econometric Theory, 10, 254-285) demonstrates the arising identification and estimation problems in singular equation systems when the error vector obeys an autoregressive scheme, as an extension of restricted least squares. Unfortunately, his main theorem concerning the identification of such systems, does not hold in general, though.identification

Fully restricted linear regression: A pedagogical note

This paper presents a comprehensive approach to estimation and hypothesis testing under a set of full restrictions, some of these arising from adding-up conditions on the endogenous variable. In contrast to the existing statistical literature, this paper uses an argumentation style familiar from classical econometric textbooks, to provide an insightful, straightforward, and nevertheless rigorous exposition of this topic.Restricted least squares Adding-up Singularity Wald-Test SUR.

Consistency of nonlinear regression quantiles under Type I censoring weak dependence and general covariate design

For both deterministic or stochastic regressors, as well as parametric nonlinear or linear regression functions, we prove the weak consistency of the coefficient estimators for the Type I censored quantile regression model under different censoring mechanisms with censoring points depending on the observation index (in a nonstochastic manner) and a weakly dependent error process. Our argumentation is based on an exposition of the connection between the residuals of the economically relevant model at the outset of the censored regression problem, and the residuals which are subject to the corresponding optimization process of censored quantile regression. In dieser Arbeit wird die schwache Konsistenz der Koeffizientenschätzer für das zensierte (Typ I) Quantilsregressionsmodell unter sehr allgemeinen Bedingungen -- lineare und nichtlineare Regressionsfunktionen, deterministische und stochastische Regressoren, Zensierungsgrenzen die (in nichtstochastischer Weise) vom Beobachtungsindex abhängen sowie schwach abhängige Fehlerterme -- bewiesen. Die Argumentation basiert dabei auf dem Zusammenhang zwischen den ökonomischen relevanten Residuen des Ausgangsmodells und den Residuen die Gegenstand der Zielfunktion des Optimierungskalküls der zensierten Quantilsregression sind.Quantil ; Nichtlineare Regression; Typ I Zensierung; Quantile regression ; nonlinear regression ; Type I censoring

Prior Information: The Mixed Prediction Approach

This paper addresses the combination of incomplete prior and sample information. In difference to the mixed estimation approach developed by H. Theil and A.S. Goldberger, dealing with prior knowledge of regression coefficients, we consider prior information on future observations of the dependent variable(s). This prior information could be given in the form of experts' expectations, or from estimations and/or projections of additional models. A framework for the incorporation of this prior knowledge in least squares estimation and prediction is developed. The approach is particularly useful when only aggregated information on the endogenous variables is available, as is often the case with regional level data.

The Diversification Benefits of Free Trade in House Value

This paper finds that homeowners could substantially reduce house price risk if they would reinvest their housing wealth in a market portfolio of houses. Free trade in the value of the house among homeowners would allow them to do so. To quantify the diversification benefits of free trade in house value, we estimate simple CAPM and APT models based on a detailed panel dataset of house price changes in the Netherlands. We find that about 92 to 96 percent of house price risk is diversifiable. In most cases, these diversification benefits outweigh the hedging effectiveness of house price futures.house price risk, free trade, financial market, diversification, futures

Origin and history of the old catholic group of churchs; their doctrinal and liturgical position; and the development of their relations with other non-papal communions

In this thesis a brief survey of the Jansenist dontroversy will be given in so far as this came to affect the fortunes of the remnant that was left to the Papal Church in Holland after the triumph of Protestantism in the United Provinces
