Revisiting the Role of Collaboration in Creating Breakthrough Inventions

Manufacturing & Service Operations Management (accepted)

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... [Read More]

Anchored Differentiation - The Role of Temporal Distance in the Comparison and Evaluation of New Product Designs


A new design can be compared with its contemporaries or older designs. In this study, we argue that the temporal distance between the new design and its comparison play an important role in understanding how a new design’s similarity with other designs contributes to its market valuation. Specifically, we argue... [Read More]

On Styles in Product Design - An Analysis of U.S. Design Patents

Management Science 2018

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...
