Economists are skeptical about the economic benefits of hosting "mega-events" such as the Olympic Games or the World Cup, since such activities have considerable cost and seem to yield few tangible benefits. These doubts are rarely shared by policy-makers and the population, who are typically...

This paper models the causes of the 2008 financial crisis together with its manifestations, using a Multiple Indicator Multiple Cause (MIMIC) model. Our analysis is conducted on a cross-section of 85 countries; we focus on international linkages that may have allowed the crisis to spread across...

Conventional wisdom holds that protectionism is counter-cyclic; tariffs, quotas and the like grow during recessions. While that may have been a valid description of the data before the Second World War, it is no longer accurate. In the post-war era, protectionism has not actually moved...

This paper shows how the richer frequency and variety of fiscal policy shocks available in an international sample can be analyzed recognizing the heterogeneity that exists across different countries. The main conclusion of our empirical analysis is that the question 'what is the fiscal policy...

With increasing sophistication, economists have been estimating gravity equations for five decades. Robust evidence shows that borders and distance impede trade by much more than tariffs or transports costs can explain. We therefore advocate investigation of other sources of resistance, despite...

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...

We study the relationship between geography and growth. To do so, we first develop a dynamic spatial growth theory with realistic geography. We characterize the model and its balanced growth path and propose a methodology to analyze equilibria with different levels of migration frictions. We...

The aim of this paper is to identify possibilities for guiding policy in the area of basic research. We provide an extended review of basic research and offer new insights on its linkages to key economic variables and economic growth. After defining what basic research is, we identify and...

The majority of microfinance impact studies focus on finding their effect on a specific group of beneficiaries, in contrast we aim to identify the impact on whole economies (economic growth, and financial sector development and reductions in income inequalities), which is an important policy...

This paper estimates the heterogeneous responses to the 2001 income tax rebates across endogenously determined groups of American households. Around 45% of the sample saved the entire value of the rebate. Another 20%, with low income and liquid wealth, spent a significant amount. The largest...
