Modern econometrics stresses the diagnostic testing of estimated models as an important part of the model-building process. In a survey article published in this journal (Pagan and Vella 1989), methods for testing the validity of the assumptions underlying the censored regression of the Tobit...

A non-technical introduction to the question of modeling with time-varying parameters, using the beta coefficient from Financial Economics as the main example. After a brief introduction to this coefficient for those not versed in finance, the book presents a number of rather well known tests...

The Breusch-Godfrey test for autocorrelated errors is generalised to cover systems of equations, and the properties of 18 versions of the test are studied using Monte Carlo methods. We show that only one group of tests regularly has actual size close to the nominal size; namely the likelihood...

This article highlights the until quite recently neglected political-economic thinking in matters of defense in twentieth-century Britain. It argues that retrieving such analyses from the interwar years is an excellent although partial way to get at an alternative picture of interwar defense...

This book presents an applied econometric analysis of the demand for food in the Nordic countries. A system of demand equations, based on the neoclassical theory of consumer demand, is analyzed using modern econometric techniques for estimation and evaluation. The models investigated are mainly...

The conference, 'Measurement Error: Econometrics and Practice' was recently hosted by Aston University and organised jointly by researchers from Aston University and Lund University to highlight the enormous problems caused by measurement error in Economic and Financial data which often go...
