(1). Which theorem states that free trade leads to an equalization of wages and rental rates in two trading countries? Explain How and Why wages and rental rates ultimately equalize.
(2) What happens to the production of both goods in a country when there is an increase in labor? Which theorem will you apply here?
Give diagrams to show this and explain clearly
(1) Factor price equalization theorem states that free trade
leads to an equalization of wages and rental rates in two trading
countries. The theorem states that as the prices of the commodities
in two trading countries equalize, then the price of factors such
as labour and capital also equalize. This also implies that the
wages and rental rates also equalize in both the trading
countries.
In a market, the productivity depends on the marginal rate of
productivity which depends on the number of labours and capital
used. The marginal productivity of a factor and the amount of
labour or capital is inversely related, as a result of which the
marginal productivity falls as labour increase. Likewise the value
of productivity depends upon its price and once a country is
allowed to trade freely with another country, the output prices
become equal. As a result of which, the factor prices, wage and
rental rates also equalize in both the nations. Thus, they end up
having same labour-capital ratio as well.
