We consider a cointegrated system generated by processes that may be fractionally integrated, and by additive polynomial and generalized polynomial trends. In view of the consequent competition between stochastic and deterministic trends, we consider various estimates of the cointegrating vector...

The purpose of this paper is to introduce and examine two alternative, although similar, approaches to the Moving Blocks and subsampling Bootstraps to bootstrapping the estimator of the parameters for time series regression models. More specifically, the first bootstrap is based on resampling...

We develop in this paper a general econometric methodology referred to as the Simulated Asymptotic Least Squares (SALS). It is shown that this approach provides a unifying theory for 'approximation-based' or simulation-based inference methods and nests the Simulated Nonlinear Least Squares...

We propose and derive the asymptotic distribution of a tapered narrow-band least squares estimator(NBLSE) of the cointegration parameter Atilde;ƒAcirc;ŽAtilde;‚Acirc;² in the framework of fractional cointegration.This tapered estimator is invariant to deterministic polynomial trends. In particular,...

We propose and derive the asymptotic distribution of a tapered narrow-band least squaresestimator (NBLSE) of the cointegration parameter Icirc;² in the framework of fractional cointegration. Thistapered estimator is invariant to deterministic polynomial trends. In particular, we allow for...

Companies invest millions of dollars in various forms of marketing communications to impact customers' awareness, attitudes, purchases and, ultimately, profitability. An important question for marketers and shareholders alike is: what effects do marketing investments have on market performance?...

We question previous research assuming that privatizing firm performance generally benefits from decreasing state ownership and the passage of time, both of which purportedly align principal-agent incentives promoting organizational decision-making that increases shareholder value. When state...
