Question

(a) How important is rent from extraction of renewable and non-renewable resources to distinguish between Net Domestic Product (NDP) and Environmentally adjusted Domestic Product (EDP). Will the distinction be valid if we have an economy with only renewable resources and the economy reaches the point of maximum sustainable yield? (20 marks)

(b) "Balanced and unbalanced growth strategies are not substitutes but complementary to each other." Discuss. (15 marks)

(c) "Income inequality is not a cause of concern as long as per capita income is rising." Critically examine this statement. (15 marks)

Resource Rents, NDP, and Green Accounting

Traditional Net Domestic Product (NDP) deducts only the depreciation of manufactured capital from Gross Domestic Product, ignoring the liquidation of natural wealth. Environmentally adjusted Net Domestic Product (EDP) rectifies this by subtracting the depletion of natural capital and environmental degradation from NDP (EDP = NDP - Natural Capital Depletion).

Resource rent—the economic surplus generated above extraction costs and normal profits—is central to this distinction. For non-renewable resources, extraction permanently depletes finite reserves. Following the El Serafy method, a significant fraction of resource rent constitutes a "user cost" (capital consumption) rather than true income. According to the Hartwick-Solow rule, constant consumption requires reinvesting these resource rents into reproducible human and physical capital. If rents are consumed rather than reinvested, natural wealth declines, causing EDP to fall substantially below NDP.

In an economy possessing solely renewable resources harvested precisely at the Maximum Sustainable Yield (MSY), the rate of extraction equals the biological rate of regeneration. Under this steady state, the net stock of natural capital remains constant, rendering the user cost of extraction zero. Consequently, no capital depletion deduction is warranted. While the conceptual distinction between NDP and EDP remains theoretically valid as an accounting framework, it becomes empirically trivial at MSY, as EDP ≡ NDP.

Complementarity of Balanced and Unbalanced Growth

Balanced and unbalanced growth strategies represent complementary phases of structural transformation rather than mutually exclusive paradigms. Rosenstein-Rodan and Ragnar Nurkse advocated balanced growth via a "Big Push"—simultaneous, coordinated investments across interdependent consumer goods sectors and social overhead capital (SOC)—to overcome demand indivisibilities and limited domestic market size. Conversely, Albert Hirschman argued that underdeveloped nations face a critical shortage of capital and decision-making capabilities, necessitating an unbalanced growth strategy that deliberately creates sectoral imbalances to induce dynamic investments through forward and backward linkages.

These doctrines operate as sequential complements. Balanced investment is essential to establish foundational SOC, power, and agriculture, preventing immediate supply-side bottlenecks. Once this base exists, unbalanced growth accelerates dynamic efficiency by channelling scarce capital into high-linkage leading sectors. India’s early planning illustrates this complementarity: the First Five-Year Plan adopted a balanced approach, prioritizing agriculture, irrigation, and community development, which generated the wage-goods surplus and stability necessary for the Second Five-Year Plan (Mahalanobis strategy) to pursue unbalanced, heavy-industry-led industrialization.

Inequality, Growth, and Capability Formation

The proposition that inequality is benign if per capita income rises draws on the Kuznets inverted-U hypothesis and traditional trickle-down economics, presuming that capital accumulation by top earners automatically diffuses through the economy. This claim is analytically and empirically untenable.

Piketty and Chancel, alongside Deaton and Drèze, demonstrate that rapid per capita GDP growth in India has coincided with extreme concentration of wealth, with top income shares reaching historic highs while real median wages stagnated. Mean per capita income masks these distributional skews, obscuring "jobless growth" where productivity gains bypass the labour force.

From Amartya Sen’s capability perspective, persistent inequality impairs development by depriving marginalized segments of substantive freedoms, access to quality education, healthcare, and nutrition. This depresses human capital accumulation, lowers long-term Total Factor Productivity, and compresses domestic aggregate demand. Extreme inequality also fuels political capture and institutional fragility.

Conclusion

A critical examination reveals that rising per capita income cannot substitute for distributional equity. A viable macroeconomic strategy must integrate green national accounting to safeguard the natural asset base, sequence balanced infrastructure with dynamic unbalanced linkages, and enforce explicit redistributive and capability-enhancing policies.
