What determines vertical scope? Transactions cost economics (TCE) has been the dominant paradigm for understanding "make" vs. "buy" choices. However, the traditional focus on empirically validating or refuting TCE has taken attention away from other possible drivers of scope, and it has rarely...

This paper shows how idiosyncratic resources can be the basis of sustained profitability and persistent heterogeneity under competitive conditions: Generic inputs purchased in the market become idiosyncratic resources by investments in customization. Analytically, we show how heterogeneous firms...

Using a novel database containing the time-series details of the organizational structure of individual bank holding companies, this paper presents the first population-wide study of the transformation in business scope of U.S. banks. Expanding scope has a negative impact on performance on...

A surprisingly neglected facet of sector evolution is the evolutionary analysis of firms', and thus a sector's, scope. Defining a sector as a group of firms that can change their scope over time, we study the transformation of U.S. banking firms. We undertake a sectoral, population-wide study of...

Designing a firm’s boundaries can lead to substantial strategic regeneration. But the question is, how? Moving beyond transaction-level analysis, we consider how the design of the firm’s overall boundaries (rather than individual make-vs-buy choices) yield strategic advantages in addition to...

This paper shows how idiosyncratic resources can be the basis of sustained profitability and persistent heterogeneity under competitive conditions: Generic inputs purchased in the market become idiosyncratic resources by investments in customization. Analytically, we show how heterogeneous firms...

When do firms expand abroad? Theory to date suggests that global expansion happens when firm-specific competitive advantages outweigh country-specific difficulties in operating abroad. Differences in culture, in legislation, in administrative practices, and in the overall institutional...

This paper considers how ideas from evolutionary theory and the neo-Schumpeterian tradition can be fruitfully combined with ideas from Herbert Simon and the Carnegie tradition on decomposability and cognitive limits. Rather than focusing on any one individual issue, this paper outlines a...

The concept of vertical architecture defines the scope of a firm and the extent to which it is open to final and intermediate markets. A firm can make or buy inputs, and transfer outputs downstream or sell them. Permeable vertical architectures are partly integrated and partly open to the...
