The repetition of shocks explains why the economy is never at its long-run equilibrium

In the usual macroeconomic models, at the long-run equilibrium: Inflation is determined by money supply growth; The real interest rate balances supply and demand for goods and services; The relative prices of assets and goods are constant; External debt is stabilised by movements in the exchange rate. However, when one looks at economic trends over a long period of time, none of these long-run mechanisms is apparent. This situation can be interpreted in two ways: Either the usual macroeconomic models do not match reality; Or the economy never reaches the long run because there are always shocks that set off a short-run dynamics.
