We implement a new approach for the identification of news shocks about future technology. In a VAR featuring a measure of aggregate technology and several forward-looking variables, we identify the news shock as the shock orthogonal to technology innovations that best explains future variation...

In this paper, we estimate government purchase multipliers for a large number of OECD countries, allowing these multipliers to vary smoothly according to the state of the economy and using real-time forecast data to purge policy innovations of their predictable components. We adapt our previous...

We do not have a good measure of the effects of fiscal policy in a recession because the methods that we use to estimate the effects of fiscal policy -- both those using the observed outcomes following different policies in aggregate data and those studying counterfactuals in fitted model...

In this paper, we estimate government purchase multipliers for a large number of OECD countries, allowing these multipliers to vary smoothly according to the state of the economy and using real-time forecast data to purge policy innovations of their predictable components. We adapt our previous...

The existence of a natural resource curse has been a longstanding theme in the economic literature and in policy discussions. We propose an alternative mechanism and study its policy implications. The mechanism is based on the interaction between two building blocks: specialization in...

We study linkages between financial development, international trade, and long-run growth using data since 1880 for seventeen now-developed "Atlantic" economies and a set of cross-country and dynamic panel data models. We find that finance and trade reinforced each other before 1930, but that...

Virtually all economies experience recurrent fluctuations in economic activity that persist for periods of several quarters to several years. Further, there is a definite tendency for the business cycles of developed countries to move together--there is a world component to business cycles. This...

This paper investigates the determinants of business cycle comovement between countries. Our dataset includes over 100 countries, both developed and developing. We search for variables that are robust' in explaining comovement, using the approach of Leamer (1983). Variables considered are (i)...

We offer a new explanation as to why international trade is so volatile in response to economic shocks. Our approach combines the uncertainty shock idea of Bloom (2009) with a model of international trade, extending the idea to the open economy. Firms import intermediate inputs from home or...

We develop a dynamic multi-country general equilibrium model to investigate forces acting on the global economy during the Great Recession and ensuing recovery. Our multi-sector framework accounts completely for countries' trade, investment, production, and GDPs in terms of different sets of...
