The Gilded Enclave: A Quantitative Analysis of Linkage Elasticity, Crowding Out, and Structural Transformation

This dissertation examines the structural implications of developing countries' services-led growth model through the lens of structural transformation. India has achieved significant export growth in services, particularly IT and business process outsourcing. This expansion has occurred alongside limited industrial deepening and uneven labour absorption. This dissertation aims to introduce structurally introduce the concept of a service enclave economy: a highly productive sector globally and nationally but one that isn't deeply embedded in terms of the backward and forward linkages it produces in the domestic economy, limiting its potential as the engine for structural transformation. This paper further dives into the structural, political economy, macroeconomic as well as coordination implications of such enclaves. Using input-output tables, eigenvector centrality as well as a Social Accounting Matrix (SAM), the paper introduces the concept of linkage elasticity of growth to capture the extent to which sectoral expansion generates additional domestic economic activity as well as an enclave index. The analysis finds that India’s leading export sector, IT services, exhibits high value added intensity but relatively low domestic linkage density and embeddedness domestically, showing strong enclave-like characteristics. In contrast, manufacturing sectors such as motor vehicles and textiles display stronger backward linkages. Further, the paper documents significant asymmetries in tax burdens, export orientation, and import dependence across sectors. The paper delves into the political economy aspects as well as welfare aspects of such growth, highlighting the potential distortionary behaviour that may emerge from 2nd order consumption including potential systemic credit channels, unequal distribution of growth as well as spatial crowding out. In this regard, this paper also introduces the concept of attention crowding out, a political economy phenomenon of uneven allocation of political attention, structurally favouring certain industries while potentially not capitalising on transformational gains for the broader economy The findings suggest that India’s growth trajectory is characterised by the expansion of a globally competitive but domestically weakly integrated service sector alongside an underdeveloped industrial base. This paper argues that such a configuration may constrain the depth of structural transformation by limiting both the propagation of growth through domestic linkages and the broad distribution of income. The results contribute to the literature on structural transformation by highlighting the role of sectoral linkage structures in shaping development outcomes in services-led economies.
