Estimating the structural mannequin while accounting for the transition path would require fixing for equilibrium transition paths at every set of parameters that the estimation algorithm searches by. Household Dollar targets urban and low-revenue buyers, whereas Dollar Tree goes after the suburban middle-earnings shopper. So whereas the concept behind the protocol might have been easy, its implementation was anything however. Dollar shops exploded throughout the good Recession and have continued to do well through the COVID-19 pandemic and the current inflationary interval. Dollar Normal, for instance, has constructed 75 p.c of its shops in small rural towns with fewer than 20,000 folks, and pinpoints new places in areas which might be 15 to 20 miles (24 to 32 kilometers) away from the nearest massive-field store or grocery store.

To match the result of Huberman and Stanzl (2004), I additionally characterize the set of viable pricing rules without momentum traders and a controller, which I merely refer to as the maximal set.
