Final answer:
Efficiency wages are theorized to boost productivity by paying workers above-market rates, but they can also lead to higher unemployment as wages may continue to rise even when productivity does not. Over time, however, unemployment levels tend to normalize as wages adjust to reflect true productivity levels. The correct answer to the question is a. increase productivity but increase unemployment.
Step-by-step explanation:
Efficiency Wages and Their Impact on Productivity and Unemployment
The concept of efficiency wages posits that by paying workers a wage that is above the market equilibrium, employers can incentivize higher productivity and lower job turnover. However, there is a trade-off to consider between productivity and unemployment when implementing efficiency wages.
When productivity is rising, as in scenario (a), there is an increased demand for labor, driving wages up. However, if productivity stops increasing and wages continue to rise due to delayed adjustment in expectations, the supply of labor exceeds the demand, resulting in unemployment. Employers who continue to pay these higher wages may do so under the belief that it will ensure a more productive and stable workforce, even though the immediate effect is an excess supply of labor, thus increased unemployment.
In contrast, scenario (b) illustrates a situation where productivity has been stagnant but then rises unexpectedly. If wages do not immediately adjust upward in response to the increased productivity, the result will be an excess demand for labor at current wage levels, leading to low unemployment.
Overall, in both cases, wages and productivity do tend to align over time. Therefore, the answer to the question about the effects of efficiency wages is a. increase productivity but increase unemployment. Efficiency wages can lead to increased productivity because they incentivize workers to perform better, but they also can result in higher than equilibrium unemployment if wages are kept high regardless of the changes in productivity.
It's important to note that over time, as employers and workers adjust their expectations, the levels of unemployment will gradually align with the new productivity norms, as wages adjust to more accurately reflect productivity levels.
