Applying Random Coefficient Models to Strategy Research: Identifying and Exploring Firm Heterogeneous Effects

by Juan Alcácer, Wilbur Chung, Ashton Hawk and Gonçalo Pacheco-de-Almeida

Abstract

Strategy aims at understanding the differential effects of firms’ actions on performance. However, standard regression models estimate only the average effects of these actions across firms. Our paper discusses how random coefficient models (RCMs) may generate new insights about firm heterogeneity and its effects on performance in empirical settings in strategy. RCMs allow testing for and predicting firm-specific coefficients, thereby distinguishing between effects that have a significant mean versus significant variance. RCMs may also be used to explore the sources of firm heterogeneous effects. We develop a simulation testbed using synthetic datasets to show that RCMs are more precise at allocating firm heterogeneous effects to model slopes and intercepts than standard regression models. We also discuss RCMs’ possible limitations due to sample size requirements, nonconvergence problems, and potentially restrictive assumptions. Overall, RCMs allow strategy researchers to test and build new theories at a more granular level.

In late 2010, Michael Tsamaz was appointed CEO and Chairman of Greek telecommunications company OTE. OTE still exhibited many traits of a large incumbent organization, with high personnel costs, crippling bureaucracy, lack of customer-centricity, a dull brand, and eroding profitability. Tsamaz was taking over the reins at a time of deep economic crisis in Greece, which would impact the options available to him to transform the company.

In October 2015, Google restructured into Alphabet, a holding company, which analysts said would facilitate innovation among its diverse subsidiaries. But when news reports surfaced revealing struggles within Alphabet companies including Nest, the smart thermostat maker, observers began to wonder if the reorganization made sense after all.
