Abstract
Harrod under analysis: path-dependence, historic time and endogenous structural change. The article aims to demonstrate how the Harrod's approach (1937, 1938, 1948) can offer theoretical elements to form a complex, historicists and non-determinist view of the economic system. The relaxation of the constant warranty rate hypothesis make possible the system suffers endogenous qualitative change. It results in the notion of path-dependence and historic time. By the endogenization of the expectations and the existence of turn-points mechanisms, this approach allows a synthesis between non-convergency and economic regulation.

Summary
Harrod under analysis: path-dependence, historic time and endogenous structural change. Aumentando os investimentos (não necessariamente em formação líquida de capital8), os empresários aceleram o crescimento efetivo, via o mecanismo de interação multiplicador/acelerador, permitindo uma ampliação da divergência entre G e Gw. Por sua vez, quanto maior for a diferença G – Gw >0, tanto maior será o estímulo para a acumulação de capital, elevando a diferença. Tanto a expansão econômica quanto a recessão econômica são engendradas por uma frustração de expectativas empresariais, que se expressa na diferença entre as taxas efetiva e garantida de crescimento, assim como entre os coeficientes efetivo e requerido de capital. Tal contexto encoraja os empresários a reduzirem a produção, assim como, possivelmente, diminuírem os recursos destinados à ampliação da capacidade produtiva
