Do you think that prices are more or less sticky today than 50 years ago? Why?

What will be an ideal response?

Less sticky. Information technology and rapid introduction of competing substitutes for goods and services enables consumers to be more price sensitive and for producers to avoid/mitigate menu costs. Workers, too, are more price sensitive and accepting of labor market flexibility. The logic of staggered price setting still applies, but rapid and deep common knowledge of market conditions enables some de facto synchronization of pricing decisions.
