What Is Characteristic of the Relationship Between Unemployment Insurance and Job-Search

What is characteristic of the relationship between unemployment insurance and job-search effort?

A) Unemployment insurance raises structural unemployment because it reduces the job search of the unemployed.
B) Most economists are sceptical of the value of unemployment insurance because they believe that it results in a poorer match between workers and jobs.
C) A typical unemployed worker near the end of the time in which he or she can receive benefits increases job-search efforts.
D) Unemployed people need to put less job-search effort now than they did in 1971 because in 1971 the conditions to receive unemployment benefits were stricter than today.
