Russia's Economy in Decline: Evidence from Consumer Behavior - Econ Lessons
Hi, my name is Mark, and I like to look at microeconomic data in Russia. At the microeconomic level, recent trends in Russia indicate a deterioration in consumer welfare consistent with an economy under stress. In this case, the substitution effect is the evidence. One observable manifestation is the increase in average body mass index (BMI), which can be interpreted as an indirect indicator of consumption downgrading rather than rising prosperity.
Standard consumer theory predicts that when real disposable income falls or becomes uncertain, households adjust their consumption patterns through the substitution effect. Specifically, consumers substitute away from higher-quality, more expensive goods toward lower-cost, calorie-dense, lower-quality substitutes in order to maintain caloric intake while remaining within tighter budget constraints. These substitutes typically offer lower nutritional quality per unit of expenditure but higher caloric yield per ruble.
In the Russian case, rising BMI is consistent with this theoretical mechanism. Rather than reflecting increased affluence, the pattern aligns with budget-constrained optimization, where households prioritize short-term energy sufficiency over long-term health outcomes. This behavior is commonly observed in economies experiencing real income compression, elevated uncertainty, or declining purchasing power.
Importantly, this pattern constitutes revealed-preference evidence of economic stress. Consumers choices signal that relative prices and income constraints have shifted, forcing a reallocation toward inferior goods in the microeconomic sense. Such behavior contradicts narratives of broad-based economic stability or improvement, as rising living standards are typically associated with dietary upgrading rather than nutritional degradation.
Therefore, rising BMI in Russia should be interpreted not as a sign of prosperity, but as a microeconomic indicator of declining household welfare, reinforcing other macroeconomic signals of stagnation and instability. The evidence suggests that Russian consumers are increasingly adopting defensive consumption strategies, which is inconsistent with an economy performing well or sustainably.
