问题如下：
An economist expects the following:
• The decline in the unemployment rate will result in higher revenues for home retailers.
• A tighter labor market will put upward pressure on wages, compelling home retailers to raise prices.
Which type of inflation best corresponds to the economist’s expectations?
选项：
A. Stagflation
B. Cost-push inflation
C. Demand-pull inflation
解释：
B is correct.
Cost-push inflation refers to the situation in which rising costs, usually wages, compel businesses to raise prices.
考点： cost-push inflation
解析：题目描述的情况都涉及增加工资的情况，上涨的工资会抬升人力成本劲儿提升人力成本。这就会造成 cost-push inflation。
tighter labor market是什么意思？是就业率高了还是低了？谢谢
