which of the following will cause an outward (rightward) shift in supply?\na. a technological improvement.\nb. the cost of an input increases.\nc. a decline in labor productivity.\nd. a reduction in consumer incomes.
Answer
Brief Explanations:
A technological improvement allows producers to make more output with the same resources, increasing supply and shifting the supply - curve rightward. An increase in input cost raises production cost, reducing supply and shifting the curve leftward. A decline in labor productivity means less output per unit of labor, reducing supply and shifting the curve leftward. A reduction in consumer incomes affects demand, not supply directly.
Answer:
A. A technological improvement
