Does monetary tightening reduce research, venture capital, and patenting?
Core argument: A 100bps monetary tightening shock lowers investment in intellectual property products in the national accounts by about 1%, a magnitude comparable to the decline in traditional physical investment, and cuts R&D spending among Compustat public firms by about 3%.
We normalize the shock to tightening by 100bps. Investment in intellectual property products (IPP) in the national accounts (NIPA) declines by about 1%. The magnitude is comparable to the decline in traditional investment in physical assets. R&D spending in Compustat data for public firms declines by about 3%. VC investment is more volatile, and declines by as much as 25% at a horizon of 1 to 3 years after the monetary policy shock. Patenting in important technologies declines by up to 9% 2 to 4 years after the shock. An aggregate innovation index constructed using estimates of the economic value of patents also declines by up to 9%. Based on estimates of the output and total factor productivity (TFP) sensitivity to the aggregate innovation index, a 9% decline in the index can contribute to 1% lower real output and 0.5% lower TFP 5 years later.
