When firms span related product categories, spillovers across categories become central to firm strategy and industrial policy, due to their potential to foreclose competition and affect innovation incentives. We exploit major new product innovations in one medical device category, and detailed...

Entrepreneurs must choose between alternative strategies for bringing their idea to market. They face uncertainty regarding both the quality of their idea as well as the efficacy of each strategy. While entrepreneurs can reduce this uncertainty by conducting tests, any single test conflates the...

Using data from a prominent online platform for launching new digital products, we document that the composition of the platform's 'beta testers' on the day a new product is launched has a systematic and persistent impact on the venture's success. Specifically, we use word embedding methods to...

Does the offshoring of production degrade or enhance the innovative capabilities of manufacturing firms? We contribute to this debate by exploiting a policy shock that differentially affected the ability of Taiwanese firms to offshore some products to China. We find causal evidence that...

This paper is an attempt to explain diffusion in the production of an innovation. Diffusion in production is defined as the increase in number of producers, or net entry, in the market for a new product. It is to be distinguished from the more familiar problem in the literature on technical...

A major challenge facing statistical agencies is the problem of adjusting price and quantity indexes for changes in the availability of commodities. This problem arises in the scanner data context as products in a commodity stratum appear and disappear in retail outlets. Hicks suggested a...

The theoretical literature on platforms and network effects predicts that the initial growth and takeoff of a platform crucially depends on the market's expectations of the future installed base. This paper tests this claim, reporting on a field experiment in which invitations to join a newly...

Why do firms outsource research and development (R&D) for some products while conducting R&D in-house for similar ones? An innovating firm risks cannibalizing its existing products. The more profitable these products, the more the firm wants to limit cannibalization. We apply this logic to the...

This study examines the effect of price regulation and competition on launch timing and pricing of new drugs. Our data cover launch experience in 15 countries for drugs in 12 therapeutic classes that experienced significant innovation over the decade 1992-2003. We use prices of established...

This study presents new empirical evidence on the relationship between investments in new computer-based information technology (IT) and productivity by investigating several plant-level mechanisms through which IT could promote productivity growth. We have assembled a data set on plants with a...
