consider the following regression

ln(GDP) = 0.80 + 0.70 ln (M2V) + 0.10 ln (debt)

where GDP = Gross National Product

M2V = velocity of money

debt = National debt

choose the correct interpretation of the coefficient of debt

		if debt increase by 1 unit, GDP will increase by 0.10 units, assuming all other variables remain constant.
		if debt increases by 1 unit, GDP will increase by 0.10 %, assuming all other variables remain constant.
		if debt increases by 1%, GDP will increase by 0.10 %, assuming all other variables remain constant.
		if debt increases by 1%, GDP will increase by 10%, assuming all other variables remain constant.

consider the following regression

ln(GDP) = 4.68 + 1.5 (M2V) + 0.0007 saving

where GDP = Gross National Product

M2V = velocity of money

Saving = National Saving

choose the correct interpretation of the coefficient of debt

		if M2V increase by 1 unit, GDP will increase by 1.5 units, assuming all other variables remain constant.
		if M2V increases by 1 unit, GDP will increase by 1.5%, assuming all other variables remain constant.
		if M2V increases by 1 unit, GDP will increase by 150%, assuming all other variables remain constant.
		if M2V increases by 1% unit, GDP will increase by 1.5%, assuming all other variables remain constant.
