When the cost of machinery components increases, the following effects on the price of machinery would occur:
-
The aggregate supply curve would shift to the left. - True. An increase in component costs raises production costs for machinery, leading to a decrease in aggregate supply at existing price levels.
-
Per-unit production prices for machinery would rise. - True. As production costs increase due to higher component prices, manufacturers would pass on some of these costs to consumers, resulting in higher per-unit prices for machinery.
-
The aggregate supply curve would shift to the right. - False. This would not happen as an increase in component costs typically leads to a decrease in supply, not an increase.
-
Machinery prices would be frozen at current levels. - False. Prices are unlikely to remain frozen if production costs are rising; manufacturers generally adjust prices in response to cost changes.
In summary, the correct effects would be the first two options.
