What effect can a rise in the wage rate have on the aggregate supply?

A rise in the wage rate typically leads to an increase in production costs for businesses since labor is one of the main inputs in the production process. When wage rates rise, businesses may face higher costs for the same level of output. Given that businesses often seek to maintain their profit margins, they may respond to these increased costs by reducing the quantity of goods and services they produce, which would result in a decrease in aggregate supply.

Furthermore, if production costs rise significantly, businesses might also pass these costs onto consumers in the form of higher prices, which can further influence the overall economic equilibrium. Therefore, a rise in the wage rate usually constrains the ability of the economy to produce at previous levels, thus leading to a decrease in aggregate supply rather than an increase or no effect at all.
