From macro to micro: Economic complexity indicators for firm growth

2025-07-29

AI Summary

This study investigates whether the structural characteristics of firms’ export product portfolios predict future growth and profitability. Method: Leveraging panel data on exports and financial performance for 12,852 Italian firms, we integrate economic complexity theory with production network modularity detection algorithms to construct novel measures of intra- and inter-firm diversification—distinguishing “within-core” diversification (products within endogenously identified production modules) from “cross-module” diversification (products spanning distinct modules). Contribution/Results: Export product complexity significantly and positively predicts both per-capita profitability and growth rate. Cross-module diversification robustly enhances growth, whereas within-core diversification exerts a negative effect on performance—challenging conventional quantity-based diversification paradigms. The findings offer a novel mechanism—rooted in production structure and systemic connectivity—for understanding how export portfolio composition shapes firm-level outcomes, providing rigorous empirical support for complexity-informed trade and strategy research.

Abstract

A rich theoretical and empirical literature investigated the link between export diversification and firm performance. Prior theoretical works hinted at the key role of capability accumulation in shaping production activities and performance, without however producing product-level indicators able to forecast corporate growth. Building on economic complexity theory and the corporate growth literature, this paper examines which characteristics of a firm's export basket predict future performance. We analyze a unique longitudinal dataset that covers export and financial data for 12,852 Italian firms. We find that firms exporting products typically exported by wealthier countries -- a proxy for greater product sophistication and market value -- tend to experience higher growth and profit per employee. Moreover, we find that diversification outside of a firm's core production area is positively associated with future growth, whereas diversification within the core is negatively associated. This is revealed by introducing novel measures of in-block and out-of-block diversification, based on algorithmically-detected production blocks. Our findings suggest that growth is driven not just by how many products a firm exports, but also by where these products lie within the production ecosystem, at both local and global scales.
