Abstract: | Many applied economists face problems in selecting an appropriate technique to estimate short and long-run relationships with the time series methods. This article reviews three alternative approaches viz., general to specific, vector autoregressions and the vector error correction models. As in other methodological controversies, definite answers are difficult. It is suggested that if these techniques are seen as tools to summarize data, as in Smith (2000 Smith, RP. 2000. “Unit Roots and all that: the impact of time-series methods on macroeconomics”. In Macroeconomics and the Real World, Edited by: Backhouse, RE. and Salanti, A. 199–215. Oxford: Oxford University Press. [Google Scholar]), often there maybe only minor differences in their estimates. Therefore a computationally attractive technique is likely to be popular. |
