Document Summary

Potential gdp: the real gdp that the economy could produce if the labor force and other resources were fully employed. Production function: mathematical depiction of the relationship between an economy"s inputs and outputs. An economy"s production function shows the volume of output that can be produced from given inputs (labor, capital) given the available technology. For the most part, economists agree; faster growth is generally preferred to slower growth. Growth rate of potential gdp depends on. Growth rate of the labor force. Growth rate of the nation"s capital stock. Labor productivity = total output/ total hours. This measures output per hour of work. Gdp can be expressed as = hours of work x labour productivity. The equation above in growth rates is: growth rates. Faster growth may lead to greater pollution, crowding, and waste production. Greater consumption may not necessarily make people happier. Growth may drive people to work longer hours. Faster growth may generate higher inflation, in some cases.
