This paper develops a two-country model that incorporates offshoring opportunities, and analyses the effects of tariffs under economic stagnation in a liquidity trap that causes unemployment. We find that a rise in tariffs on imports of outsourced goods contributes to an increase in employment by inducing a shift in production, but also leads to an appreciation of the real exchange rate that tends to reduce employment. The effect of real exchange rate appreciation dominates the effect of the production shift, and accordingly employment and consumption fall. The effects of tariff adjustments are reversed, however, when there is no liquidity trap and hence no unemployment. 1 See Davidson et al. (1999), Moore and Ranjan (2005) and Helpman and Itskhoki (2010) for studies on the relationship between trade liberalization and unemployment that include search frictions, but do not consider offshoring opportunities.
2A study close to ours is Hashimoto (2011), who considers offshoring in a stagnation economy and examines the effects of an exogenous change in a Leontief production technology. In this setting, however, tariff policy does not affect offshoring activity, because there is no substitution between home factors and offshoring factors.The Japanese Economic Review 6 This is a non-trivial set-up because labour costs differ between the two countries. Even if we incorporate an opportunity for offshoring by foreign firms, the implications of the model remain mostly unchanged.The Japanese Economic Review P P satisfy 9 We assume that households have access to international bonds. Enders and Mueller (2009) discuss the implications of different international asset market structures for the transmission of technology shocks.
