We test the trade finance channel of exports by controlling for the bank credit channel. Using Turkey’s July 2012 adoption of Basel II as a quasi-natural experiment, we examine whether shocks to trade financing costs affect exports. With data for 16,662 Turkish exporters shipping 2,888 different products to 158 countries, we find that the share of letters-of-credit-based exports decreases (increases) when the associated risk weights for counterparty exposure increase (decrease) after the adoption of Basel II. However, growth of firm-product-country-level exports remains unaffected. Trade financing might have a lesser role in exports than previously suggested by the previous literature.

We document strong skill matching in Turkish firms’ production networks. Additionally, in the data, export demand shocks from rich countries increase firms’ skill intensity and their trade with skill-intensive domestic partners. We explain these patterns using a quantitative model with heterogeneous firms, quality choices, and endogenous networks. A counterfactual economy-wide export demand shock of 5% leads both exporters and nonexporters to upgrade quality, raising the average wage by 1.2%. This effect is nine times the effect in a scenario without interconnected quality choices. We use the model to study the conditions for the success of export promotion policies.

We examine the propagation of a small unexpected supply shock through a production network and the role financial constraints play in its transmission. Using data on almost all Turkish supplier-customer links, we exploit the heterogeneous impact of an unexpected import-tax increase for identification. We find that this relatively minor shock had a nontrivial economic impact on exposed firms and propagated downstream through affected suppliers. Importantly, we show that low-liquidity firms amplified its transmission.
