The authors examine the issue of lag-length selection in the context of a structural vector autoregression (VAR) and a vector error-correction model with long-run restrictions. First, they show that imposing long- run restrictions implies, in general, a moving-average (MA) component in the...

The paper provides three principal results. First, we benchmark South African infrastructure performance in terms of access, pricing, and quality against key comparator groups of countries using the most recent World Bank benchmarking data base (2005). Second, we establish clear empirical links...

This statement outlines the objectives and policies of the new journal, Macroeconomic Dynamics, which is dedicated to the advancement of macroeconomics as a science. This Editorial is to appear at the front of the first issue of that journal and is copyright by Cambridge University Press.

In recent years simulation-based estimation of multinomial probit (MNP) models has attracted an increasing interest among econometricians. With the help of more powerful and cheaper computers, MNP models have become a well-accepted alternative to multinomial logit (MNL) models that impose the...

This paper tests and confirms asymmetry in the Fiji gasoline price adjustment equations with respect to changes in the crude oil prices. More satisfactory specifications and estimation are used than in the earlier studies. It is found that two alternative approaches viz., the Granger two-step...

Based on the Partial Distribution (Feng Dai, 2001), a new model to price an asset (MPA) is given. Going a step further, this paper puts forward the Multivariate Partial Distribution (MPD) for the first time. By use of MPD, we could gain a new kind of model for pricing the group assets (MPGA), in...

This paper constructs the probability space underlying the random variable of any time dependent econometric specification. The construction links concrete economic activity, both perceived and recorded, and econometric formulations. Furthermore, it is argued that the probability events...

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...

The Nelson–Olsen covariance estimator of the simultaneous least squares-probit model is adjusted to accommodate probability based stratified surveys. A simultaneous model of body mass and the propensity to exercise provides an empirical example using stratified survey data.

The flattening of the world thanks to the cluster of profound socio-economic and politico-cultural changes has created unprecedented challenges for organizational leadership and management. The fast evolving global world of ours where challenges have to be continually met requires timely...
