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 correctStatement 1 Statement 2 （）①A. CorrectCorrect ②B. Incorrect Correct ③C. CorrectIncorrect
A. ①
B. ②
C. ③
参考答案：C
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.
