Socioeconomic Challenges in Education: Inequality, Risk, and Rational Investment Decisions

The persistence of socioeconomic challenges related to inequality and unequal access to education highlights the need for a deeper theoretical understanding of how households make educational investment decisions under unequal conditions. Despite extensive research on human capital and inequality, a significant gap remains in explaining how rational households respond to socioeconomic challenges when educational returns, borrowing constraints, and risk simultaneously depend on existing socioeconomic inequality. The aim of this study is to develop a new theoretical expected utility framework that explains rational underinvestment in education under conditions of socioeconomic inequality. The proposed theoretical concept integrates three interrelated mechanisms: background-dependent private returns to education, inequality-sensitive borrowing constraints, and an inequality-driven risk penalty affecting educational payoffs within a concave human capital production function. The scientific novelty of this framework lies in providing a unified microeconomic model that endogenously explains lower educational investment among disadvantaged households without relying on behavioral biases, informational failures, or non-standard preferences. Unlike existing models, the proposed approach explicitly links inequality not only to financing constraints but also to heterogeneous returns and risk-adjusted educational outcomes, thereby capturing their joint and reinforcing effects. The model reveals that higher inequality reduces optimal educational investment when the combined credit-tightening and risk-penalty effects outweigh any increase in expected returns, demonstrating a clear mechanism through which inequality depresses schooling decisions. Furthermore, the framework establishes that optimal educational investment is strictly increasing in parental wealth under positive risk-adjusted marginal returns, generating an endogenous and widening educational gradient across socioeconomic groups. The findings contribute to addressing socioeconomic challenges by providing a theoretical basis for policy interventions targeting credit access, risk mitigation, and equalisation of educational returns, while opening avenues for future research on dynamic and general equilibrium extensions of inequality and human capital formation.
