How much does region affect performance?

Abstract

Purpose – The importance of regional strategy as a separate paradigm in the international business literature has grown in recent years, and the initial connections between regionalization and firm performance appear promising. What is lacking, however, is an empirical analysis quantifying the impact of regional effects on firm profitability. This topic is an important one for the field of international business, as drivers of firm profitability are some of the key motivators of research in international strategy. The aim of this paper is to empirically quantify the role of regional effects on the performance of service firms in a manner such that regional effects can be directly compared with country and firm effects on firm profitability. Design/methodology/approach – Using a hierarchical linear model (HLM) with four levels, the proportion of variation driven by regional effects is estimated. These estimates are obtained from a data panel of 48,083 units from 7,129 service firms across the three triad regions (North America, Europe, and Asia Pacific) over a ten-year time-frame (1999-2008). Findings – It was found that regional effects, in terms of relative importance, explain approximately 9 percent of the variance in firm performance. This pattern of results is consistent when the analysis was conducted during periods of increasing or decreasing profits, firm type, and ownership structure. Originality/value – Within the context of international business, work on regional strategy/regionalization has emerged as a separate stream of literature. This study is one of the first to quantify the influence of regional effects on performance using a 4-level HLM model. Additionally, this paper demonstrates the application of a 4-level model, potentially increasing awareness of this technique and usage in other multilevel topics in the IB literature, which offers several avenues for future research.
