摘要：Real output growth in an economy, over the medium-term, can be thought of as a combination of labour force growth, which reflects population growth, and productivity growth in that economy. Employed labour and productivity are the most important factors in output generation and, consequently, the output potential of an economy is largely determined by employment and productivity potential. Employment potential, in tum, is determined by the labour force and a "full-employment" unemployment rate. Finally, the labour force is determined by the size of the source population (for example, 15 years and over) and a "full-employment" labour force participation rate. This linkage of population growth to real output growth is a well-established feature of most macroeconomic models.
