Scientific models of macroeconomic systems must not only be internally coherent but also compatible across scales, time horizons, modeling traditions, and empirical implementations. The domain spans accounting identities, growth theory, business-cycle models, heterogeneous-agent frameworks, reduced-form macro relations, and policy rules. Compatibility requires that these components can be embedded within one unified descriptive system of aggregate dynamics, such that shifting viewpoint (micro ↔ macro, static ↔ dynamic, deterministic ↔ stochastic, short-run ↔ long-run) does not fracture the theory into mutually incompatible subsystems.
Key compatibility principles include:
Reduction to Established Limits (Correspondence Principle)
- New or refined macroeconomic models must reproduce established results in regimes where classical macro theory is known to apply.
Dynamic stochastic models must reduce to static equilibrium conditions when shocks vanish; heterogeneous-agent models must converge to representative-agent benchmarks under symmetry; short-run models with frictions must collapse to long-run growth or steady-state relationships when adjustment frictions are removed. Policy rules should reproduce neutral outcomes in limits where policy effects are assumed absent. If an aggregate framework fails to recover accepted macro results in these limits, it breaks continuity with the body of macroeconomic knowledge it claims to extend.
Convergence and Consilience of Evidence / Models
- Independent macroeconomic models and empirical measurements should converge on compatible descriptions of aggregate behavior.
National accounts, financial flow-of-funds data, labor statistics, survey expectations, and structural macro models should not imply incompatible stories about growth, inflation, employment, or cycles for the same economy and period. Persistent divergence between theoretical predictions and multiple empirical indicators signals a compatibility problem that must be resolved through improved measurement, revised assumptions, or clearer scope. Robust macroeconomic knowledge depends on cross-validation, where different models and data sources agree in overlapping domains.
Preservation of Key Invariants and Principles
- Fundamental macroeconomic invariants must be preserved across models, scales, and representations.
These include accounting identities (income equals expenditure), conservation of stocks and flows (capital, debt, money), non-negativity of real quantities, and invariance to normalization or units (real vs. nominal consistency). Reformulating macro models—changing variables, aggregating sectors, or rescaling units—must not alter implied dynamics or equilibria unless the model explicitly introduces new mechanisms. Preserving these invariants ensures that diverse macro frameworks remain compatible expressions of the same aggregate system.
Internal Logical Consistency and Formal Rigor
- All elements of the macroeconomic framework must fit together into a single logically self-consistent system.
Behavioral assumptions, accounting identities, stochastic processes, policy rules, and dynamic equations must not contradict one another or generate incompatible aggregate outcomes. A model cannot simultaneously assume market clearing and binding rigidities without redefining equilibrium; it cannot impose budget constraints while violating intertemporal solvency. Compatibility at this level requires that macroeconomics be expressible as one coherent system of aggregate dynamics rather than a collection of disconnected modeling conventions.
These structural requirements—correspondence to established limits, convergence across models and evidence, preservation of core invariants, and strict logical coherence—define compatibility in the domain of aggregation and dynamics. They ensure that macroeconomic systems remain unified, interpretable, and continuous across scale, time, and modeling approach.
