Motivation
Rising concerns about possible use of trade restrictions.
Debate about costs and benefits of trade policy as a macroeconomic policytool
I Boost output, rebalance external accounts, or address distributional effects oftrade
I Influential scholars argued that temporary tariffs may be beneficial in aliquidity trap, thanks to the inflationary effect of higher import costs (e.g.,Eichengreen, 2016)
We study the short-run effects of protectionism on macroeconomicfluctuations both empirically and theoretically

Contribution
1 Estimate effects of temporary trade barriers using country-level and panelVARs
I Quarterly/monthly data on product-level antidumping investigations (whichtypically lead to the imposition of tariffs)
I Annual data on applied tariff rates
2 Transmission of tariff shocks:
I SOE with key macro/trade ingredients: physical capital, nominal rigidities,endogenous trade structure (firm heterogeneity + sunk/fixed entry costs)
I Baseline scenario mirrors the empirical analysis: normal times under a flexibleexchange rate
I Model counterfactuals where protectionism advocated as potentially beneficial:(i) liquidity trap and (ii) fixed exchange rate regime

2 Macro and micro dynamics behind the contractionary effects of tariffsI Macro level: expenditure switching vs. decline in real income and investment
(coupled with contractionary monetary policy response)

Temporary Trade Barriers
On average, exporters face low applied tariffs but frequently changingtemporary trade barriers (TTBs)
I Antidumping duties, global safeguards, and countervailing duties
Antidumping (AD) duties are the primary policy exceptions to WTO rules
I Account for 80%-90% of all TTBs across countries
Turkey and India: largest and most active users; Canada among developedSOE
I Up to 6% of imported products affected by TTBs in Turkey (' 1% of GDP)I 2% in Canada (0.5% of GDP; higher prior to 2001)
GAD (Bown, 2016): product-level data on AD investigations and relatedtariffs:

Understanding Magnitudes
Three peaks of AD initiatives in Canada (1997:Q4, 1999:Q3, 2001:Q1)
Consider 2001:Q1
I AD initiatives in the steel sector worth ' 30% of sectoral imports
I Steel sector output was 1.1% of GDP (including IO linkages)
All AD initiatives led to the imposition of tariffs
Median imposed tariff equal to 56%

2 Shares in a mutual fund of domestic tradable-sector firms
3 Physical capital accumulation
Household sets wnt (h) subject to a quadratic wage-adjustment cost

Counterfactual Scenarios
Use the model to study scenarios where temporary trade barriers advocatedas potentially beneficial
1 Is protectionism expansionary when countries are in a liquidity trap (ZLB)?
2 Can protectionism be beneficial under a fixed exchange rate?
Same trade policy shock considered in normal times

Protectionism in a Liquidity Trap
Evidence and theoretical analysis suggest that protectionism is inflationary
Through this channel, τ IMt may help lift the economy out of a liquidity trap
We perform the following exercise:
1 At t = 0, risk-premium shock Λa,t depresses output and generates deflation(binding ZLB)
1 + Λat = (1 + it+1)Et
(βt,t+1
1 + πC ,t+1
)
1 + ψa∗,t+1 + Λat =(1 + i∗t+1
)Et
(βt,t+1
1 + π∗C ,t+1
Qt+1

)
- Interpretation for Λat : shock to the demand for safe/liquid assets
2 At t = 1, unanticipated tariff increase

Protectionism under a Fixed Exchange Rate
Widespread diffusion of pegs, crawling pegs, and very narrow bands (Reinhartand Rogoff, 2004)
Recent experience of Ecuador (dollarized economy) illustrates the issue
I Broad range of temporary tariffs in 2015-2016 to fight a balance-of-paymentscrisis
I Trade balance effectively improved but real GDP further declined, togetherwith consumption and investment
In contrast to typical conclusion of textbook models, we find thatprotectionism remains contractionary under a peg

Conclusions
1 Structural VARs using trade-policy and macro data at different frequency
I Temporary trade barriers act as a negative supply shockI At best a small positive effect on the trade balance
2 Small-open economy model with key macro/trade ingredients reproducesVAR evidence
I Both macro and micro dynamics behind the contractionary effects of tariffs
3 Policy takeaway: protectionism remains a bad idea—at least for small openeconomies
I Even when in a liquidity trap and regardless of exchange rate arrangementsI Detrimental economic effects even when abstracting from retaliation from
trade partners
