Business method innovation in US manufacturing and trade

Using text analysis of business method (BM) patents, we show that BM innovation in the US manufacturing and trade sectors improves how a firm targets customers, manages product delivery, or enhances the product through service offerings. We then show that BM innovation creates value on average, but the value is larger when (1) it is engaged by trade (vs. manufacturing) firms; and (2) the firm's BM innovation covers the range of customer targeting, product delivery, and product service support.

Anchored differentiation: The role of temporal distance in the comparison and evaluation of new product designs

Comparative processes are crucial to how consumers evaluate design. What we show, however, is that consumers can be sophisticated in such comparisons. Given a novel design, they would lean on its similarities to past designs to understand its functionalities, but also lean on dis-similarities to other contemporary designs to seek distinctiveness and express their individuality.

Revisiting the role of collaboration in creating breakthrough inventions

We challenge the notion that collaboration is always better than working alone. In our study using technological and design patents we find that the decomposability of the invention significantly moderates the effectiveness of the lone inventor. Particularly, tasks that are less decomposable relatively advantages the lone inventor. We also show that lone inventors working on non-decomposable inventions and who have collaborated widely in the past outperforms even teams.

On styles in product design: An analysis of US design patents

We show how one can identify styles (categories of product design that are perceived to be similar) using design patents. Using this data set we show that (i) style turbulence (unpredictable changes in style) is increasing over time, and (ii) technological turbulence (unpredictable changes in technology) have a U-shaped relationship to style turbulence. I use this data platform to study other questions (see e.g., "Anchored Differentiation").
