Financial Constraints and propagation of shocks in production network

This study finds that even small unexpected supply shocks propagate downstream through production networks and are amplified by firms with short-term financial constraints. The unexpected 2011 increase in the tax on imports purchased with foreign-sourced trade credit is examined using data capturing almost all Turkish supplier-customer links. The identification strategy exploits the heterogeneous impact of the shock on importers. The results indicate that this relatively minor, non-localized shock had a non-trivial economic impact on exposed firms and propagated downstream through affected suppliers. Additional empirical tests, motivated by a simple theory, demonstrate that low-liquidity firms amplified its transmission.
