1、CGD NOTE|NOVEMBER 2022Shock-Proofing the Semiconductor Supply Chain:The Role of Industrial and Other Policies Shahid YusufSome years back,the mathematician Clive Humby1 asserted that data was the“new oil”however,it would be more accurate to claim that semiconductorsa scarce resource unlike datadeser
