The paper presents a new method to solve DSGE models with a great number of heterogeneous agents. Using tools from systems and control theory, it is shown how to reduce the dimension of the state and the policy vector so that the reduced model approximates the original model with high precision....

We shed new light on the determinants of growth by tackling the blunt and weak instrument problems in the empirical growth literature. As an instrument for each endogenous variable, we propose average values of the same variable in neighboring countries. This method has the advantage of...

We estimate the effects on growth of nine fiscal reform episodes in seven high-income countries using the Synthetic Control Method. These episodes are selected using an indicator-based approach applied to the evaluation of growth-friendly fiscal reforms during 1975-2010. We find that in reform...
