During a recession, firms face a decrease in demand for their goods and services. To compensate for this drop they can charge more and maintain revenues, right? Wrong. If that were the case, we’d see a significant increase in the CPI and PPI over the last few quarters, indicating a 1970s-style
stagflation. But the data
point to a deflation instead.
So why don’t prices increase? In layman’s terms: firms can’t charge more because consumers can’t afford more – they’re increasingly sensitive to price changes. But let’s not forget the multitude of microeconomic forces at play behind this simplistic and somewhat incorrect statement.
Yes, the income effect plays an important role. If people are losing jobs or watching their real wage decline, their consumption patterns will change. Usually, and I do mean usually, they’ll demand less of a particular good. But that’s not true for all goods, because the responsiveness of the quantity demanded to a change in income (also called income elasticity of demand) comes into play. For some goods, like
instant ramen and
spam (even rat meat,
according to Freakonomics), demand increases as income decreases, so producers can get away with raising prices. So what was once cheap becomes relatively more expensive. A 99-cent bag of ramen is suddenly $1.09. Counter-intuitive, isn’t it?
