To determine which factor would reduce the supply of microcomputers, let’s analyze each option:
- a) A technological improvement that lowers the cost of producing computers: This would likely increase the supply, as producers could create more microcomputers at a lower cost.
- b) Higher wage rates for the workers that assemble the computers: This would increase production costs. Higher costs can lead to a decrease in the supply, as some manufacturers might produce fewer microcomputers if it becomes more expensive to do so.
- c) A reduction in the price of computer chips: This would also lower production costs, likely increasing the supply of microcomputers since manufacturers can produce them more cheaply.
In conclusion, the option that would reduce the supply of microcomputers is b) higher wage rates for the workers that assemble the computers. This is because increased wages directly raise the cost of production, which can lead to a decrease in supply.
