Diffuse priors lead to pathological posterior behaviour when used in Bayesian analyses of Simultaneous Equation Models (SEMs). This results from the local nonidentification of certain parameters in SEMs. When this, a priori known, feature is not captured appropriately, and a posteriori favour...

We Highlight a fast subsampling method that can be used to provide valid inference in nonlinear dynamic econometric models.

The behavioural framework has several attractions to offer for the identification of multivariable systems. Some of the variables may be left unexplained without the need for a distinction between inputs and outputs; criteria for model quality are independent of the chosen parameterization; and...

In mathematical finance diffusion models are widely used and a variety of different parametric models for the drift and diffusion coefficient coexist in the literature. Since derivative prices depend on the particular parametric model of the diffusion coefficient function of the underlying, a...

Part of conventional wisdom glaned from econometric theory and the "learning" literature is that agents ahould use all the data they have for prediction. In this paper it is shown that agents can improve their prediction by throwing away data.

Linear regression models have been used in a number of studies examining the presence or absence of incremental information contents in cash flow. The results of these studies have not been consistent. This paper draws attention to the critical issue of extreme observations in the data. Extreme...

In this paper, we provide a segmentation procedure for mean-nonstationary time series. The segmentation is obtained by casting the problem into the framework of detecting structural breaks in trending regression models in which the regressors are generated by suitably smooth functions. As test...

In this paper, we examine nonlinear interrelationship between energy consumption and output level for a panel of G7 countries. For this purpose, we propose a nonlinear cointegration test in heterogeneous panels for testing the presence of a co-integrating relationship that follows a globally...
