Abstinence

Abstinence in economic context refers to refraining from or postponing consumption.

In one sentence

In economics, abstinence means postponing consumption today in order to save and invest, freeing resources for future consumption and capital formation.

Where the term comes from (and why it’s controversial)

Classical writers (notably Nassau William Senior) used “abstinence” to describe the sacrifice of not consuming, and to frame interest/profit as a reward for saving. Critics argued this can be misleading because:

  • some saving is done by households with limited choice (e.g., forced saving through pensions or limited consumption opportunities),
  • interest can also reflect productivity of capital, risk, and market power, not only “sacrifice.”

Intertemporal choice: the modern way to model abstinence

Households choose consumption across time given an interest rate and preferences. A basic tradeoff is:

  • consume $C_0$ now, or
  • save $S$ now and consume $C_1$ later, where $C_1 \approx (1+r)S$.

In many models, optimal consumption smoothing satisfies an Euler condition (one common form):

$$ u’(C_0) = \beta (1+r),u’(C_1) $$

Higher patience ($\beta$), higher interest rates ($r$), and stronger precautionary motives generally increase saving (abstinence from current consumption).

Macro implication: when “more saving” can be a problem

At the individual level, abstinence increases wealth and buffers shocks. At the aggregate level, however, a rise in desired saving can reduce demand in the short run (the “paradox of thrift”), especially when:

  • interest rates are stuck near a lower bound,
  • investment does not rise to absorb extra saving,
  • households are liquidity constrained and cut spending sharply.

Behavioral frictions

Behavioral economics highlights that abstinence can be hard even when it is optimal:

  • present bias (overweighting today),
  • self-control problems,
  • mental accounting,
  • limited attention.
  • Saving: Setting aside current resources to increase future consumption possibilities.
  • Intertemporal Choice: Decisions involving tradeoffs across time (consume now vs later).
  • Capital Accumulation: Growth of the capital stock through investment funded by saving.
  • Paradox of Thrift: If many households try to save more at once, aggregate demand can fall and incomes can drop.
