This paper proposes a strategy to increase the efficiency of forecast combination. Given the availability of a wide range of forecasts for the same variable of interest, our goal is to apply combining methods to a restricted set of models. To this aim, a hierarchical procedure based on an...

We present a model of bilateral real exchange rate determination based on different theories that can be combined into a common statistical framework. Although eclectic, the approach is successfully used to shape a final specification which performs surprisingly well when out of sample exercises...

The effect of business tax and regulation on growth, together with potential effects of government spending on education and R&D, is embodied in a model of a small open economy with growth choices. The structural model is estimated on post-war panel data for 76 countries and the bootstrap is...

In this paper we examine whether a generalized version of Flam and Helpman's (1987) model of vertical differentiation can reconcile three facts. One, countries import only a subset of available varieties. Two, import prices vary across exporters within narrow product categories. Three, US growth...

We estimate the effect of political regime transitions on growth with semi-parametric methods, combining difference in differences with matching, that have not been used in macroeconomic settings. Our semi-parametric estimates suggest that previous parametric estimates may have seriously...

Based on monthly observations, I specify an econometric model capturing the driving forces behind the crude oil price series in recent years. A large set of covariates, such as supply and demand variables as well as futures market variables, is used to test the impact on the crude oil price....
