For cost, most of the literature focuses ry floor and links cost reductions with cumulative prowhat has been termed learning by doing (Arrow, 1962), firms learn to produce a single design in a single facfficiently and thus with lower costs. Workers become sks and firms introduce better work flows (Wright, te and Epple, 1990; Adler and Clark, 1991; Thornton son, 2001), better process control (Argote, 1999; Lapre , and automated manufacturing equipment (Utterback, promote organizational learning (Benkard, 2000). holars consider cumulative production as a general ffort and thus the driver of new product and pros and thus improvements in performance and cost , 1984; Dutton and Thomas, 1984; Balasubramanian an, 2010). This formulation which is sometimes called ding author. Tel.: +65 98560674. ress: firstname.lastname@example.org (J.L. Funk). to a model linking cumulative production to the improvements (Dutton and Thomas, 1984; Ayres, 1992; Weiss et al., 2010; Nagy et al., 2013) where the relative contribution of factory floor activities and new product and process designs are unclear. On the other hand, a few scholars have questioned the importance of cumulative production and demand and the possibility that R&D effort or time may be a better independent variable (Koh and Magee, 2006, 2008;
Nemet, 2009; Nordhaus, 2009; Thompson, 2012; Funk, 2013a,b).
This paper attempts to better understand the impact of product and process design changes vs. factory floor activities on cost and performance by detailed analysis of improvements in cost and performance in a novel empirical domain. It focuses on new technologies that have experienced rapid improvements in cost and performance before commercial production has been started and it examines the specific mechanisms that enable these improvements to occur. An analysis of these mechanisms enables us to identify more specific modes of learning and to extend models of learning (Argote and Epple, 1990) into the pre-commercialization phase that some define as invention (Arthur, 2007). Our analysis suggests that key aspects of this learning include creating new materials, improving processes, and reducing scale and that this learning occurs in laboratories.
