I study a model of geopolitical organization endogenizing the size of nations, of their public spending and of their degree of openness. The optimal geography may not be a stable equilibrium and the Alesina-Spolaore bias toward too many nations tends to be confirmed. However, multiple equilibria...

In this paper we examine the role of mortgage equity withdrawal in explaining the decline of the US saving rate, since when house prices rise and mortgage rates are low, homeowners have an incentive to withdraw housing equity and this may affect the saving rate. We estimate a Vector Error...

The recent plunge in oil prices has brought into question the generally accepted view that lower oil prices are good for the US 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 lower...

Mainstream economic research regards private debt as a determinant of GDP growth in the longrun. Levine (2005) surveys in details this branch of literature and explains the channels by which debt fuels growth. In this paper we switch the focus from the long to the short-run and study whether...

We investigate the long-term macroeconomic effects of climate change across 48 U.S. states over the period 1963.2016 using a novel econometric strategy which links deviations of temperature and precipitation (weather) from their long-term moving-average historical norms (climate) to various...

We study the long-term impact of climate change on economic activity across countries, using a stochastic growth model where labour productivity is affected by country-specific climate variables. defined as deviations of temperature and precipitation from their historical norms. Using a panel...

Economic research has considered Private Debt a determinant of GDP growth for years. By keeping this perspective, the objective of this work is to understand how much of the GDP response to a monetary shock is due to the variation of private debt. This is the marginal contribution of private...

We look at a part of the spatial angle of economic growth. We introduce a new measure Spatial Population Concentration (SPC) that captures the weighted average population surrounding every person within a geographic area. The weights are a function of the distance between the person in question...

We investigate how Reconstruction affected Black political participation and socio-economic advancement after the American Civil War. We use the location of federal troops and Freedmen’s Bureau offices to indicate more intensive federal enforcement of civil rights. We find greater political...

We evaluate the proposal for official dollarization in Costa Rica by applying a new approach to measure the business cycle comovements with the United States. While the literature often focuses on the correlation of shocks, we point out that the response of each country to the shocks is also an...
