Trade Liberalization and Embedded Institutional Reform: Evidence from Chinese ExportersAmit K. Khandelwal, Columbia Business SchoolPeter K. Schott, Yale School of ManagementShang-Jin Wei, Columbia Business School
Motivation • Institutions that distort the efficient allocation of resources can have sizeable effects on aggregate outcomes • Hsieh and Klenow (2009): aggregate Chinese productivity nearly doubles if capital and labor are properly allocated among existing firms • Trade barriers distort resource allocation along both “intensive” and “extensive” margins • Institutions that manage trade barriers can cause additional distortions • Key idea: productivity gains from trade liberalization may be larger than expected if institutions that manage the trade barriers are inefficient: • Gain from removal of the “embedded institution” • Gain from removal of the trade barrieritself
China and The Multifiber Arrangement (MFA) • This paper examines the distortions associated with institutions that manage quota licensing • The global MFA restricted Chinese exports of textile and clothing to the US, EU and Canada until 2005 • Quotas were assigned by the Chinese government • Our question: were quotas assigned to the most productive firms? • Comparison of quota-bound vs quota-free goods before/after 2005 suggests entrants are more productive than incumbents, i.e., the most productive firms were not allocated licenses • Use key feature of empirical analysis to simulate “political allocation” and compute contribution of eliminating licensing to overall gain • Eliminating actual institution accounts for ~70% of overall gain • Replacing actual institution with auction raises productivity ~13%

Outline • Auction-allocation model of quota licenses • Data and Identification Strategy • Evidence of misallocation • “Political allocation” and counterfactual exercise • Conclusion
Overview of Auction-Allocation Model • Same basic structure as in Melitz/Chaney • Two countries, one industry • Monopolistic competition, CES utility • Firms are heterogeneous in productivity (j) • Exporting requires fixed and iceberg trade costs (t) • Firms optimize under quantity restriction • Quota license fee is like a per-unit trade cost (aod) to export from origin country o to destination country d (Irrazabal et al. 2010) • Price of variety with productivity j: aod > 0 imposes a disproportionate penalty on high productivity (i.e., high j) firms Analytical solutions to model not possible when aod > 0
Three Empirical Implications of Quota Removal • Export growth following quota removal is driven by the intensive margin • High productivity firms are most constrained under quotas • Their exports jump disproportionately as quotas are removed • Low-productivity enter because license fee goes to zero when quotas are removed • (Depends on TFP distribution: if density of very high TFP firms is high enough, there will be no entry and the lowest TFP firms will exit) • Incumbentsand entrants make opposing contributions to export prices • Incumbents’ prices fall as the license fee goes to zero • But removal of license fee allows high price (i.e., low-productivity) firms to enter • (Will come back to quality variant of model later)

Quotas Under the MFA/ATC • During the Uruguay Round (early 1990s), the US, EU and Canada committed to a schedule for withdrawing textile and clothing quotas in four phases • At the start of 1995, 1998, 2002 and 2005 • China’s quotas on goods in first three phases were relaxed in early 2002 following its entry into the WTO in late 2001 • We focus on the final phase • Chinese quotas were allocated by the government • Details are scarce but predominantly on the basis of “past performance” • Black-market sales of licenses complicates our analysis; appears to be a bigger issue during the 1980s than our sample period (Moore, 2002) • (More about this later)
Aggregate Chinese Textile & Clothing Exports Quota-free exports rise 29% in 2005 Quota-bound exports rise 119% in 2005 Quotas Relaxed Quota-Bound Quota-Free Notes: Quota-bound = any export constrained by a quota; quota-free = other textile and clothing goods not bound by quotas
Firm-Level Chinese Customs Data • Value and quantity exported • By firm, HS8 product, destination country and year • Focus on 2003-2005 exports to US, EU and Canada • Observe exporter’s ownership type • “SOE”: state-owned enterprise • “Domestic”: privately-owned domestic firm • “Foreign”: privately-owned foreign firm • Create two sets of HS8-country (hd) groups : • Quota-bound: subject to quota until 2004 by subset of US/EU/Canada • “Men’s cotton pajamas” to US/Canada • Quota-free: not subject to quota by subset of US/EU/Canada • “Men’s cotton pajamas ” to EU
Identification Strategy • Sample • Start with 547 HS8 products are subject to quotas by US/EU/Canada • Drop the 188 of these that are subject to quotas by all three countries • The remaining 359 HS8 products are our sample • Difference-in-differences comparison • Quota-bound (“treatment”) vs quota-free (“control”) for 2004-5 versus the same difference for 2003-4 • Changes in control group account for trends in textile-and-clothing supply (e.g., privatization) or demand (e.g., preferences) • Attribute any differential response to the removal of quotas
Quota-Bound vs Quota-Free • Compare treatment and control groups pre- and post-reform • SOE share differs substantially ex ante, but not ex post
Regression Specification • Where DYhdt is • Change in market share of incumbent SOEs • Change in market share of privately owned entrants • Etc. • Just report α3: quota-bound vs quota free in 2004-5 versus 2003-4 • Full regression results in appendix • Also do “placebo” diff-in-diffs for prior year, i.e., 2003-4 versus 2002-3 • Also add country-product FEs to control for underlying trends

Decompositions (DY) • Quantity market share changes • By margins of adjustment, ownership • Examine quantity growth to avoid price effects • Can’t aggregate quantity across HS8, so compute changes for each HS8-country pair and then average across pairs, by group • The tables I show you will be these averages • Price changes • By margins of adjustment, ownership
Margins of Adjustment • Intensive: • Incumbent: firm exports same HS8 to same country in both t-1 and t(note: EU considered single country) • Extensive • Exiter: firm exports HS8-country in t-1 but not t • Entrant: firm exports HS8-country in t but no exports in t-1 • Adder: firm exports HS8-country in tbut not t-1AND was an exporter of some other HS8-country in t-1

Price Changes Before/After Quota Removal Quota-Bound Exports
Export Price Decomposition • Decompose change in the overall MFA price between 2004-5 by margin and compare with OTC • where {f,h,d,t} index {firm,product,country,year} • Quantity-weighted avg log export price • Product-country price change ΔOverall = ΔIncumbents + ΔNet Entrants
Quality Downgrading? • Might expect prices to decline due to quality downgrading in response to quotas (Aw and Roberts 1986; Boorstein and Feenstra 1991; Harrigan and Barrows 2009) • We see prices fall in the data, but declines are concentrated among privately owned entrants (assumed to be more productive) • Nevertheless, we can compute quality-adjusted prices to check • Approach is similar to Hummels and Klenow (2005), Khandelwal (2010), Hallak and Schott (2011) • Find similar results….
Quality-Adjusted Prices • Put quality in CES preferences • Quantity demanded for each variety • Impose σ = 4, use dt fixed effects to capture price index/income, h fixed effect compares quantities and prices within products • Log quality is • Quality-adjusted prices:
Coarse, Back-of-Envelope Productivity Calculation • Identify textile and clothing exporters in the Annual Survey of Industrial Production • (Match with trade data is imperfect) • Calculate TFP of each firm assuming Cobb-Douglas, constant returns to scale • Labor coefficient is the share of wages in value added • Capital coefficient = 1 - labor coefficient • Among textile/clothing exporters • Average SOEs is 1/4 to 1/3 as productive as the average domestic and foreign firm, respectively • Consistent with literature
Coarse, Back-of-Envelope Productivity Calculation These numbers are from the market share table Multiply changes in market share by each ownership type’s mean TFP to gauge TFP gain from reallocation of 21.3% (Calculation assumes homogenous firms within ownership type)

Decomposing Productivity Gains • We want to decompose the overall productivity gain from quota removal into two parts • Part due to removal of licensing regime • Part due to removal of quota • In order to do this, we use numerical solutions of the model to compute weighted-average firm productivity under three scenarios • No quota • Auction allocation • Political allocation: a perturbation of the auction-allocation model that matches our empirical evidence of misallocation No Quota AuctionAllocation PoliticalAllocation
Numerical Solutions for No-Quota Scenario • Choose parameters of the no-quota scenario • Elasticity of substitution σ=4 (from Brodaet al. 2006) • Country sizes • Fixed and variable trade costs • Log Normal productivity distribution, LN(μ,q) • Choose (μ,q), iceberg trade costs and ratio of export to domestic fixed cost to match: • Export size distribution • Share of Chinese and U.S. textile and clothing firms that export • U.S. and Chinese import penetration in each others’ markets • Simulate productivity draws, compute cutoffs, total exports, market shares and prices
Numerical Solutions for Auction-Allocation Scenario • Use the no-quota scenario but impose the quota restrictiveness observed in data • Export quantities jump 161% in quota-bound versus quota-free goods when quotas are removed • Solve for endogenous license fee that clears the market • This license price is ~10% of the average price of an exporter • Re-compute aggregate export TFP
TFP vs Market Share, No Quota vs Auction Allocation Disproportionate penalty on high-TFP firms
Numerical Solutions for Political-Allocation Scenario • Firms have second, political draw • Correlation ρwith TFP • Re-assign market shares from auction-allocation based on this draw • Assign highest market share to the most politically connected firm, second most connected firm gets second highest share, etc. • Firm prices continue to based on true underlying productivity • Low TFP firms with high political draw get high market share • Decompose aggregate price decline between political allocation and “no quota” allocation as we did in empirical tables • Calculate contribution of price decline attributed to net extensive margin • Choose ρ to match observed 67.5% extensive-margin contribution to quality-adjusted price decline (at ρ=0.15)
