Q.1.0) For each of the following events, assume that either the supply curve or the demand curve (not both shifted). Explain which curve shifted and indicate the direction of the shift.
a.From 1950 to 1979 the wages paid to fruit pickers increased while the number of fruit pickers employed decreased.
b.During the same period the price of radio sets declined, while the number of radio sets purchased increased.
