Suppose the world price of steel rises substantially. The demand for labor among steel-producing firms in Pennsylvania will increase. The demand for labor among automobile-producing firms in Michigan, for which steel is an input, will decrease. The temporary unemployment resulting from such sectoral shifts in the economy is best described as frictional unemployment.

Suppose the government wants to reduce this type of unemployment. Which of the following would help achieve this goal? Check all that apply.

a. Increasing the benefit offered to unemployed workers through the government's unemployment insurance program

b. Improving a widely used job-search website so that it matches workers to job vacancies more efficiently
