Why do economists believe that setting a goal of zero percent unemployment is not feasible or desirable? Creating a goal of zero percent unemployment for an economy is not feasible nor is it desirable because:__________
a. workers lose jobs due to changes in output of goods and services in, the economy.
b. the economy needs some short-term unemployment in order to allow for better matching of jobs with workers that possess the proper skill sets.
c. many people retire each year and therefore they become unemployed making changes to the unemployment rate.
d. the economy always experiences cyclical unemployment even if the economy were operating at the full-employment level of output.
