Macroeconomic Implications of Structural Demographic Change in the Context of De-Globalization

Defined by an aging population, declining birth rates, and notable changes in age distributions, structural demographic change has grown to be a major factor influencing world socioeconomic paths. The continuous retreat from globalization calls into question the conventional wisdom that says more trade integration, capital mobility, and international labor movement might release internal demographic constraints. These adjusting systems are failing in the framework of the emergent de-globalized one, hence raising the direct exposure of economies to the consequences of local demographic changes. From this point of view, the current work presents a thorough summary of theoretical and empirical studies on macroeconomic effects of demographic changes. By means of a bibliometric analysis of more than 2,300 academic publications and a comparative evaluation of leading models and empirical research, this paper defines and arranges the main macroeconomic effects of demographic transition. The analysis identifies the main macroeconomic effects of demographic transition such as slow economic growth, labor market contraction, increased budgetary restrictions related to growing old-age dependence ratios, basic changes in consumption and saving patterns, and reconfiguration of world capital flows and imbalances. The study underlines the basic need of human capital development, healthcare system investment, technological innovation, and flexible government policies to slow down negative demographic trends. It also addresses the growing differences between the theories of demographic reversal and secular stagnation, both of which suggest different long-term economic consequences of population aging. Demographic aging will impede economic growth, constrict labor markets, and exert pressure on public finances without mitigating interventions. These consequences are already evident in first-wave aging societies (Europe, East Asia, North America) and will ultimately influence later-wave regions (Latin America, East Asia’s developing economy). Macroeconomic negative consequences can be overcome by internal adaptation of the economy to an ageing society and the creation of new forms of cooperation in a less globally integrated world.
