Lag or Error? - Detecting the Nature of Spatial Correlation

Larch, Mario; Walde, Janette - Society for Computational Economics - SCE - 2006

The attractiveness of spatial autoregressive models has increased significantly. The awareness of important spatial interactions arose in various fields. In economics, interactions can be due to interdependencies between entities such as states, firms, or consumers. Examples are spatial...

Statistical Tests of the Rank of a Matrix and Their Applications in Econometric Modelling

Camba-Mendez, Gonzalo; Kapetanios, George - School of Economics and Finance, Queen Mary - 2005

Testing the rank of a matrix of estimated parameters is key in a large variety of econometric modelling scenarios. This paper describes general methods to test for the rank of a matrix, and provides details on a variety of modelling scenarios in the econometrics literature where these tests are...

Prediction Error Learning and Rational Expectations in Autoregressive Models with Forecast Feedback

Zenner, M. - University of Bonn, Germany - 1994

The rational expectations hypothesis is supported if rational expectations are stable with respect to reasonable learning procedures. We consider the Stochastic Gradient-Algorithm as a boundedly rational learning procedure in an univariate ARX-Model with forecast feedback. We prove that whenever...

Model Specification Testing in Nonparametric and Semiparametric Time Series Econometric Models

Gao, Jiti; King, Maxwell - Econometric Society - 2004

We propose a simultaneous model specification procedure for the conditional mean and conditional variance in … nonparametric and semiparametric time series econometric models. An adaptive and optimal model specification test procedure is then … values. An example of implementation is given to show how to implement the proposed simultaneous model specification …

A note on the modelling of hyper-inflations

SALIES, Evens; MOFFATT, Peter - EconWPA - 2004

In time series macroeconometric models, the first difference in the logarithm of a variable is routinely used to represent the rate of change of that variable. It is often overlooked that the assumed approximation is accurate only if the rates of change are small. Models of hyper-inflation are a...

The Cowles Commission Approach, Real Business Cycle Theories, and New Keynesian Economics

Fair, Ray C. - Cowles Foundation for Research in Economics, Yale University - 1992

The Cowles Commission approach is reviewed and compared to the approaches of real business cycle (RBC) theorists and new Keynesian economists. It is argued that RBC models are not tested in a serious enough way and that the new Keynesian literature is not empirical enough for testing even to be...
