Time Preference

The preference for immediate consumption over future consumption in economic decision-making.

Background

Time preference is an essential concept in economics that explains how individuals and societies prioritize immediate versus future consumption. It underpins decisions about savings, investments, and consumption patterns over time.

Historical Context

The concept of time preference dates back to early economic thought but has been developed and formalized more explicitly in the 20th century by economists such as Eugen von Böhm-Bawerk, Irving Fisher, John Maynard Keynes, and Paul Samuelson. These developments paved the way for modern theories of intertemporal choice and growth.

Definitions and Concepts

Time preference refers to the tendency of people to prefer immediate gains over future gains of equal or greater value. This concept highlights individual or societal preferences concerning the allocation of consumption at various points in time. Related concepts include:

  • Discounting the Future: The process of reducing the value of future benefits and costs to account for time preference.
  • Social Time Preference: Collective or societal preferences towards present versus future consumption, reflecting broader socio-economic policies and objectives.

Major Analytical Frameworks

Classical Economics

Classical economists, including Adam Smith and David Ricardo, indirectly addressed time preference through their discussions on capital accumulation and interest rates, emphasizing the role of savings and investments.

Neoclassical Economics

Neoclassical economics models time preference through utility functions incorporating present and future consumption. The concept is central to the formulation of the discounted utility model proposed by Paul Samuelson.

Keynesian Economics

John Maynard Keynes addressed time preferences in the context of liquidity preference theory, where individuals prefer current liquidity over future uncertain returns, influencing interest rates and investment rates.

Marxian Economics

Marxian theory, while not explicitly focusing on time preference, examines the dynamics of capital accumulation and capitalism’s temporal inconsistencies that stem indirectly from time preferences.

Institutional Economics

Institutional economists analyze how social norms, institutions, and cultural practices affect collective and individual time preferences, offering insights into why different societies exhibit varying saving and investment behaviors.

Behavioral Economics

Behavioral economics investigates anomalies in time preference, such as hyperbolic discounting, where individuals’ time preference rates may not remain consistent over different periods, affecting their long-term decision making and self-control issues.

Post-Keynesian Economics

Post-Keynesian economics builds on Keynes’ ideas, examining how time preference interacts with financial markets, uncertainty, and expectations in a way that impacts economic stability and growth.

Austrian Economics

Austrian economists, notably Eugen von Böhm-Bawerk, focused extensively on time preferences, arguing that they drive interest rates and the structure of capital goods.

Development Economics

Time preferences profoundly impact development economics, influencing policies on savings, investment, and economic development in less developed countries.

Monetarism

Monetarists consider time preference crucial in understanding inflation rates and monetary policy, emphasizing the role of time preference in the velocity of money.

Comparative Analysis

Different economic schools offer varying perspectives on the impact of time preference on economic decision-making. Classical and Neoclassical views primarily frame it in terms of individual choice and intertemporal allocation, while Keynesian and Post-Keynesian emphasize its role in broader economic stability. Behavioral economics provides a nuanced perspective by integrating psychological dimensions that explain deviations from purely rational behavior.

Case Studies

To understand time preference, one might examine varying saving rates across countries, retirement planning behavior, or responses to policies aiming at future-oriented consumption like tax incentives for savings.
