On some relations between a continuous time Luenberger productivity indicator and the Solow model

We introduce well-known microeconomics productivity measures in Solow models discrete time or continuous by adopting a Luenberger-type approach. In each framework, we derive the indicators and dynamical paths. First, show that expression of are similar to residuals, allowing us make an analogy between firm's behavior microeconomic setting country's macroeconomic setting. Second, demonstrate properties paths both frameworks.
