Questions
I Is pass-through of exchange rates into import pricesasymmetric? Is it non-linear?
I If these asymmetries or non-linearities exist, do they tell ussomething about market structure or the nature of demand?

Preview of results
I We show that this pass-through is asymmetric: foreignappreciations tend to pass through faster.
I This result is unlikely to stem from a selection effect causingproduct exit, but price stickiness may be important in somecases.
I The importance of this asymmetry varies by sector, suggestingthat the nature of competition and price setting plays a role.
I We find no statistically significant non-linearities.
I A theory of sticky prices with strategic complementarities andcapacity constraints is generally capable of matching thesefacts.

Issue 1: Nominal rigidities
I Differences in the speed of pass-through suggest that theymay be caused by differences in price adjustment.
I If foreign appreciations cause foreign firms to adjust pricesfaster, the pass-through would be faster.
![Page 26: Asymmetries and Non-Linearities in Exchange Rate Pass-through](https://reader036.fdocuments.us/reader036/viewer/2022072608/62dea508b7538469de5a6a0a/html5/thumbnails/26.jpg)
Controlling for price stickiness: MRPT
I Following Gopinath, et al. (2010), we can eliminate the effectof nominal price rigidities on pass-through estimates byfocusing on what they call medium-run pass-through(MRPT), where subscript c denotes the cumulative changebetween time t and the last price change t − k for good ifrom country j :
∆pi ,j ,c = β+∆e+j ,c + β−∆e−j ,c + ∆Zc + εi ,t
I Unfortunately, this makes time dummies less natural, and sowe include other explanatory variables ∆Z like the U.S. CPIand a measure of global non-oil commodity prices.Country/strata fixed effects are still included.

I Conditioning on a price change, some evidence thatpass-through is still asymmetric, but only for differentiatedgoods

Issue 2: Selection
I Foreign appreciations might also induce products to exit themarket, as the desired dollar price rises and the foreign firmstops selling it rather than letting the price increase through.
I This would bias the foreign appreciation pass-through towardszero, potentially understating the true asymmetry ofpass-through.
![Page 30: Asymmetries and Non-Linearities in Exchange Rate Pass-through](https://reader036.fdocuments.us/reader036/viewer/2022072608/62dea508b7538469de5a6a0a/html5/thumbnails/30.jpg)
Searching for Selection

prob(exiti ,j ,t) =18∑k=0
{β+k ∆e+
j ,t−k + β−k ∆e−j ,t−k}+ [...] + εi ,j ,t

Non-linearities in pass-through
I Many theories of asymmetric pass-through also implynon-linear pass through: larger shocks may have higherpass-through than smaller shocks.
I Adding square and cube terms to our augmented pass-throughregression allows for differential pass-through depending onthe size of the shock.

Theory
I At the sectoral level, product entry/exit (selection) can causeasymmetries (Nakamura and Steinsson 2012)
I Product-level sources of asymmetric pass-through(Ritz 2015):
I Demand: habit formation, demand curves with non-constantcurvature
I Supply: non-constant marginal costs, capacity constraints
I Many models used in macro and trade imply symmetric ornear-symmetric pass-through.

Theory
I We proposed a simple partial-equilibrium model of stickyprices and convex costs to raising output.
I Firms face monopolistic competition, idiosyncraticproductivity shocks a, and aggregate real exchange rateshocks e. With menu cost κ, they are allowed to change theirprice, maximizing their discounted value.
V (p, a, e) = max{V A(p, a, e),VN(p, a, e)},
V A is the value of the firm if it adjusts its price:
V A(p, a, e) = maxp′
Π(p′, a, e)− κ+ βE[V (p′, a′, e ′)
],
VN is the value of the firm if it does not adjust its price:
VN(p, a, e) = Π(p, a, e) + βE[V (p, a′, e ′)
],
Π(p, a, e) is the flow profit of the firm.

Conclusion
I Foreign appreciations pass through faster than depreciations.
I Asymmetries are still present conditional on a price change.
I Selection does not appear to be strongly asymmetric.
I Non-linearities are negligible.
I A theory of sticky prices with strategic complementarities andcapacity constraints is generally capable of matching thesefacts.
