“…Such policy action is warranted because trade is an important engine of growth, in a context where growth and productivity performance in many countries has been poor. Trade, and the related expansion of global value chains, boosts growth through increased productivity by improving resource allocation, increasing scale and specialisation, encouraging innovation activities, facilitating knowledge transfer, fostering the expansion of more productive firms and the exit of the least productive ones (OECD, 2000;Nicoletti et al 2003;Westmore, 2013;Melitz and Ottaviano;, Kiriyama, 2012Bloom et al 2016;Taglioni, 2016). Policy action to restore growth in world trade intensity might be expected to raise mediumterm total factor productivity growth on average by around 0.2% per annum (Figure 3), based on recent OECD estimates of the effect of trade intensity on productivity (Égert and Gal, 2016).…”
