Abstract:

This NiGEM Observation summarises the recent empirical evidence on trade protectionism and on the relationship between economic growth and openness to trade. We find that trade restrictive policies have increased, in fact in a subdued way, whereas economists still consider international trade as a main engine for growth. Furthermore, we use an experimental version of NIGEM to illustrate the effects from increases in tariffs. We do this by generating a scenario in which the US increases the price of Chinese imports to the US by 10 per cent. This equates to tariffs on 13.8 per cent of total US imports given 2010 trade shares. As a consequence of this policy change, our simulation suggests a temporary reduction in US output of 0.2 per cent relative to its baseline after 1.5 year. This negative effect kicks in immediately, spurred by inflationary pressures that are partially offset by a decrease in imports. At the same time, our scenario suggests only a modest change in the overall trade balance of the US.

In the next section we document the empirical literature review. Afterwards, we analyse the increase in tariffs from a theoretical point of view, and present the results of our simulation in the last section. This analysis is complimentary to Hacche and Liadze (2017), who expand on this topic with US tariffs applied to greater number of countries alongside a set of ‘retaliatory’ scenarios.
