Se analiza, dado un objetivo a largo plazo del ratio inversión pública/PIB, este ratio, además va a reaccionar a lo largo de la transición según el estado de la economía. Esta regla de inversión pública es mas flexible que la que es comunmente considerada en la literatura, donde la ratio inversión publica/PIB es constante. En comparación con esta simple regla, y bajo regímenes impositivos alternativos, se obtienen importantes ganancias de bienestar al coordinar de manera óptima la política de corto y largo plazo. Modelling the accumulation rule evolving public investment is an issue of utmost interest among economists and politicians. The present paper extends the Barro (1990) model of productive government expenditure by considering a time-adapted rule for the public investment/output ratio. The rule allows a particular target on the public investment ratio to be achievable in the long-run. Additionally, throughout the transition, the government may adjust its period-by-period public investment/output ratio in response to the current productivity of public capital relative to its long-run level. The degree of this response depends on a short-run policy instrument, which is decided by the fiscal authority simultaneously to the long-run target ratio. That way, the government problem could be interpreted as a coordination problem between short- and long-term policies. In comparison with a constant-ratio rule, and under alternative taxing scenarios, important welfare improvements are found when coordinating the short- and the long-run policy instruments in an optimal way.
