consumers defy inflation

NEW YORK — Fueled by pay gains, solid hiring and enhanced savings, Americans sharply ramped up their spending at retail stores last month in a sign that many consumers remain unfazed by rising inflation.

Retail sales jumped 3.8% from December to January, the Commerce Department said Wednesday, a much bigger increase than economists had expected. Though inflation helped boost that figure, most of January’s gain reflected more purchases, not higher prices.

Last month’s increase was the largest since last March, when most households received a final federal stimulus check of $1,400. The fact that consumer spending remains brisk even after government stimulus has faded — enhanced unemployment aid ended in September — suggests that Americans’ pay is rising enough to drive a healthy pace of spending and economic growth.
