We employ a set of sign restrictions on the generalized impulse responses of a Global VAR-model, estimated for 38 countries/regions over the period 1979-2011Q2, to discriminate - between supply-driven and demand-driven oil-price shocks and to study the time profile of their macroeconomic effects...

This paper studies the long-run impact of public debt expansion on economic growth and investigates whether the debt-growth relation varies with the level of indebtedness. Our contribution is both theoretical and empirical. On the theoretical side, we develop tests for threshold effects in the...

This paper investigates the global macroeconomic consequences of falling oil prices due to the oil revolution in the United States, using a Global VAR model estimated for 38 countries/regions over the period 1979Q2 to 2011Q2. Set-identification of the U.S. oil supply shock is achieved through...

The recent plunge in oil prices has brought into question the generally accepted view that lower oil prices are good for the United States and the global economy. In this paper, using a quarterly multi-country econometric model, we first show that a fall in oil prices tends relatively quickly to...

This paper studies the impact of the level and volatility of the commodity terms of trade on economic growth, as well as on the three main growth channels: total factor productivity, physical capital accumulation, and human capital acquisition. We use the standard system GMM approach as well as...
