We show that, in general, consistent estimates of cost pass-through are not obtained from reduced-form regressions of price on cost. We derive a formal approximation for the bias that arises even under standard orthogonality conditions. We provide guidance on the conditions under which bias may...

This paper explores the gains from trade in differentiated products from three channels: decreases in price, improvements in quality, and increases in variety. Using data on Indian imports of computer printers from 1996 to 2005, a period of trade liberalization, I find that quality was the...

Exporting firms continuously change export destinations. We present reduced-form evidence indicating firms are more likely to export to countries that are geographically close to their previous destinations. This evidence for path dependence in exports is robust to controlling for firm-country...

We demonstrate that cost pass-through can be used to inform demand calibration, potentially eliminating the need for data on margins, diversion, or both. We derive the relationship between cost pass-through and consumer demand using a general oligopoly model of Nash–Bertrand competition and...
