The Garrison model coordinates macroeconomics with capital theory, illustrating how consumption and investment decisions are balanced over time. In a healthy economy, the rate of interest acts as a price signal that coordinates the plans of savers with those of capital builders.

If consumers choose to save more, the interest rate falls, signaling to businesses that they can sustainably finance longer, more capital-intensive stages of production (early stages). However, if the central bank artificially lowers interest rates through credit expansion, it creates a clashing signal: consumers consume more because credit is cheap, while businesses overinvest in early-stage capital projects. This coordination failure causes systemic malinvestment, which eventually leads to a recession.

Building on Friedrich Hayek's seminal essay "The Use of Knowledge in Society", prices are not merely ratios at which goods are exchanged; they are an information communication system. The critical knowledge required to coordinate an economy is dispersed, subjective, and tacit—it cannot be aggregated or calculated by a central planning board.

When scarcity changes or consumer preferences shift, prices adjust. This signal coordinates millions of independent decisions without anyone needing to know the specific cause of the change. When interest rates or currency values are manipulated by central policy, the information carrying capacity of prices is corrupted, leading to widespread structural mistakes.

Mainstream economic theory often treats capital as a homogeneous fund, denoted simply as "K". Austrian economics rejects this. Capital is a highly complex, heterogeneous structure composed of specific machines, buildings, and tools that must be aligned sequentially in time.

This structure is bounded by time preference—the degree to which actors value current goods over future goods. A lower time preference leads to increased savings, which lowers the interest rate and extends the structure of production to support more complex, productive processes. Without real savings to support these structures, long-duration projects cannot be completed, leading to structural liquidations.

The Socialist Calculation Debate, initiated by Ludwig von Mises, demonstrated that rational economic allocation is impossible without market prices. Without private ownership of capital goods, there is no market for them, and without a market, there are no prices. Without prices, cost-risk calculations cannot be computed.

For investors, the calculation problem highlights the danger of central planning. Any attempt to dictate interest rates, credit flows, or resource pricing introduces calculation failures. Investors must evaluate businesses based on how well they discover real prices rather than relying on planning agency subsidies or distorted credit structures.

Mainstream finance models assume markets are in continuous equilibrium and attempt to manage risk through historical volatility metrics. Austrian economics, by contrast, focuses on uncertainty, subjective expectation, and dynamic coordination processes.

For long-term capital allocators, the Austrian framework provides a shield against credit-induced bubbles. Austrian theory highlights why long-duration assets may carry distinct risks during credit-driven malinvestment phases, and why capital structure resilience matters in such analysis.
