Endogenous productivity of demand‐induced R&D: evidence from pharmaceuticals

Abstract: We examine trends in the productivity of the pharmaceutical sector over the past three decades. Motivated by Ricardo's insight that productivity and rents are endogenous to demand when inputs are scarce, we examine the industry's aggregate Research and Development (R&D) production function. Using exogenous demand shocks to instrument investments, we find that demand growth can explain a large portion of R&D growth. Returns to scale have been stable, whereas total factor productivity has declined significantly.… Show more

“…The pressure generated by demand conditions, which drives firms to innovate, is a fact widely reported in the innovation literature (BOON; EDLER, 2018), since its proposition by Schmookler (1966), and corroborated mainly for hightech products and manufacturing industries (JUSTMAN, 1994;PORTER, 1998b;BÖNTE, 2004;FABRIZIO;THOMAS, 2012;LÜTHJE;HERSTATT;VON HIPPEL, 2005;EVANSCHITZKY et al 2012;KUTSCHKE;RESE;BAIER, 2016;MOEN;TVEDTEN;WOLD , 2018;MYERS;PAULY, 2019). In other words, in markets with more demanding consumers, intense feedback on solutions developed by ecosystem companies generates more pressure on companies, which can help explain even the differences in innovation rates between countries.…”

“…For drugs with alternatives available for the same medical indication, "the daily price of the new medicine is to be equal to that of the comparable drug, to secure fair competition in the market" [34, pp. [13][14][15]. Price competition is then intentionally absent as between drugs.…”

“…In contrast, for drugs without available alternatives, the "cost calculation method" is used, which rests on manufacturing, R&D and marketing costs along with provision for an "operating profit of 14.7%" [34, pp. [13][14][15]. Furthermore, drug prices calculated through either method are "adjusted in case of large disparity between average foreign price, [as determined by the] average of US, UK, Germany and France."…”

“…None of this literature has attempted to incorporate the growing body of evidence of how the quantity and quality of pharmaceutical innovation responds to payment (Acemoglu & Linn, 2004; Adams, 2021; Bennette et al., 2019; Blume‐Kohout & Sood, 2013; Cerda, 2007; Dubois, de Mouzon, Scott‐Morton, & Seabright, 2015; Finkelstein, 2004; Myers & Pauly, 2019; Rake, 2017; Toole, 2012) to identify the optimal level of reward to manufacturers which accounts for the long‐term value beyond IPP, while carefully distinguishing the consumption value of health and the health opportunity costs associated with health care expenditure. Equally, the empirical literature has not estimated the likely effect of payment on health outcomes, or other welfare arguments, to identify what level of payment might be optimal and evaluate which pricing policies or approval norms would deliver this payment.…”
