Question

there has been change in GDP but why not in employment explain

Answer 1

One version of Okun's law has stated very simply that when unemployment falls by 1%, GNP rises by 3%. Another version of Okun's law focuses on a relationship between unemployment and GDP, whereby a percentage increase in unemployment causes a 2% fall in GDP.

Answer 2

GDP means gross domestic product it means that the total value of goods and services produced within in a year in a country

EMPLOYMENT includes several factors of the opportunities

Either the new educated people are not enough for jobs or they have to be self employed so there is a change in GDP

Hope it helps :-)
