We model technological and financial innovation as reflecting the decisions of profit maximizing agents and explore the implications for economic growth. We start with a Schumpeterian endogenous growth model where entrepreneurs earn monopoly profits by inventing better goods and financiers arise...

We construct a model where the equilibrium organization of firms changes as an economy approaches the world technology frontier. In vertically integrated firms, owners (managers) have to spend time both on production and innovation activities, and this creates managerial overload, and...

This Paper develops a dynamic general equilibrium model of North-South trade with scale-invariant growth. Northern firms devote resources to innovative R&D to discover higher quality products and Southern firms devote resources to imitative R&D to copy state-of-the-art quality Northern products....

In a two-country Schumpeterian growth model, we study the incentives for basic research investments by governments in a globalized world. We find that a country's basic research investments increase with the country's level of human capital and decline with its own market size. This may explain...

This paper develops a dynamic general equilibrium model of North-South trade and economic growth. Both innovation and imitation rates are endogenously determined as well as the degree of wage inequality between Northern and Southern workers. Northern firms devote resources to innovative R&D to...

We analyse an economy where managers engage both in the adoption of technologies from the world frontier and in innovation activities. The selection of high-skill managers is more important for innovation activities. As the economy approaches the technology frontier, selection becomes more...

Estimating the effect of trade on capital flows is difficult given the inherent identification problem. We use fluctuations in rainfall to capture the exogenous variation in trade between Germany, France, the U.K., and the Ottoman Empire during 1859-1913. The provisionistic policy of the Ottoman...

This paper analyzes the joint behavior of international capital flows by foreign and domestic agents--gross capital flows--over the business cycle and during financial crises. We show that gross capital flows are very large and volatile, especially relative to net capital flows. When foreigners...

This paper investigates the empirical link between fiscal vulnerabilities and currency crashes in advanced economies over the last 130 years, building on a new dataset of real effective exchange rates and fiscal balances for 21 countries since 1880. We find evidence that crashes depend more on...

This paper presents a model of international portfolios with real exchange rate and non financial risks that accounts for observed levels of equity home bias. A key feature is that investors can trade equities as well as domestic and foreign real bonds. Bonds matter: in equilibrium, investors...
