单选题
A labor market analyst makes the following assertions about trends in labor income:
Statement 1: The net effect of technological improvements has been to increase the demand for labor. This can be seen in the long-run increase in real wage rates.
Statement 2: The broadest measure of labor income is total wages, salaries, and tips received. Are these two statements correct?
Statement 1 Statement 2
①A. Correct Correct
②B. Incorrect Correct
③C. Correct Incorrect
A. ①B. ②C. ③
【正确答案】
C
【答案解析】Statement 1 is correct. Technological improvements increase demand for some types of labor and decrease demand for other types, but the net long-run effect has been to increase demand for labor as a whole. The long-run increase in real wage rates is evidence that supports this assertion. Statement 2 is incorrect. A more complete measure of labor income is total labor compensation, which includes employer-provided benefits as well as wage and salary income.
