  • What is a perfect substitute?
  • As you can see, the case of perfect substitutes is an extreme example of this kind of behavior: when the price of one good increases beyond a certain threshold, the optimal bundle jumps from buying only one good to buying only the other.
  • Which is better DOP or ROP?
  • In problem classes with D = high, the best results are achieved for DOP. On the other hand, ROP yields the lowest average relative deviation if I = 717 and D = medium.
  • Are substitution patterns well-approximated by a CES specification?
  • This suggests that the substitution patterns in the data are not well-approximated by a CES specification; the ordinal price metric of the best price is typically required to match the substitution patterns in the variable weight index.
  • What is a demand oriented price (DOP)?
  • Demand-oriented prices(DOP): For DOP, we choose the highest price point rjn′at which the entire capacity of the product jcan be sold: rjn′=maxn∈{1,…,Nj}{rjn|c0j⩽|Bjn|}. 5.2. Improvement heuristics To find nearly optimal solutions, we implement local search heuristics in various ways.
  • How do time series of prices for close substitute products affect prices?
  • the time series of prices for close substitute products are negatively correlated a common shock leads to the change in V L and V H ). We take as our objective aggregating prices such that the change in our price aggregate over time would form an exact price index.
  • Do consumers substitute heavily to products that are promoted?
  • They found, in a supermarket context, that consumers substitute heavily to products that are being promoted even when the promoted prices are not the lowest. Such observations have led to many suggested alternatives to the BLS approach.
