In the present study, we propose a simple test approach based on the work of Breitung and Candelon (2006), which allows us to test for asymmetric predictability at a pre-specified frequency. The test approach can also be used to test for causality in cointegrated systems, as illustrated by...

Measuring customer lifetime value (CLV) in contexts where customer defections are not observed, i.e. noncontractual contexts, has been very challenging for firms. This paper proposes a flexible Generalized Simulation-based estimation Framework (GSF) for predicting lifetimes and measuring...

This paper considers dynamic panel models with a factor error structure that is correlated with the regressors. Both short panels (small T) and long panels (large T) are considered. With a small T, consistent estimation requires either a suitable formulation of the reduced form or an appropriate...

This paper assesses the applicability of a dynamic discrete choice model in accounting for the observed OLS and IV estimates of the Mincer equation parameter on returns to education. I estimate a dynamic model of schooling and employment choices using an extended version of Keane and Wolpin...

This paper develops a wavelet (spectral) approach to test the presence of a unit root in a stochastic process. The wavelet approach is appealing, since it is based directly on the different behavior of the spectra of a unit root process and that of a short memory stationary process. By...

In countries where tools of economic control are immature and disabled due to totalitarian systems, macroeconomic analyses for aggregate quantities and relationships, such as total consumption, investment, and government expenditures represents a difficult task. The practice of aggregation...

In recent years, the government, of African Countries has assumed major responsibilities for economic reforms and growth. In attempting to describe their economies, economists (policymakers) in many African Countries have applied certain models that are by now widely known: Linear programming...

Most of the surveys in social sciences generally consist of ordinal variables. Sometimes researchers need to model behaviour of ordinal variables in simultaneous equation system involving many endogenous ordinal variables. This situation leads to a very complex likelihood function which is...
