BCG Protectionism and the Business Cycle 24th April 2018 1 / 44

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

Results

1 Empirical analysis: temporary trade barriers act as a negative supply shock

I Recessionary, inflationary, with (at best) a small positive effect on the tradebalance/GDP

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)

I Micro level: reallocation of market shares towards less efficient domesticproducers

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%

Robustness

Results are also similar when considering India

Variety of robustness checks

I Additional controls (i.e. oil price, Kilian index of global economic activity)

I Focus only on AD investigations that end up with tariffs

Counterfactual Scenarios

BCG Protectionism and the Business Cycle 24th April 2018 32 / 44

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

BCG Protectionism and the Business Cycle 24th April 2018 33 / 44

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

)

- 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
