摘要:Business cycles are an economic phenomenon of many dimensions. Usually, they are investigated at the aggregate level, where the main objective is to uncover stylized facts about the relationships between key national variables. To get a better idea of the source and dynamics of business cycles, international studies have been undertaken where national models were explicitly linked. However, for many countries, the analysis must be disaggregated at the regionallevel: a measure like C.N.P. is not necessarily a good indicator of the true economic conditions prevailing in a particular region. Considering Canada's institutional organization and the diversity of its industrial base, a regional analysis is eminently appropriate.
