Focusing on tail effects, I incorporate distributions for temperature change and its economic impact in an analysis of climate change policy. I estimate the fraction of consumption w*(τ) that society would be willing to sacrifice to ensure that any increase in temperature at a future point is...

"Any economic analysis of climate change policy requires some model that describes the impact of warming on future GDP and consumption. Most integrated assessment models (IAMs) relate temperature to the level of real GDP and consumption, but there are theoretical and empirical reasons to expect...

What is an optimal or a sustainable external debt - for a country, region or sector? How should one monitor and evaluate debt to preclude a crisis? We use stochastic optimal control/dynamic programming to derive an optimal debt. The deviation of the actual from the optimal will serve as a...

Based on empirical data, a two-equation game-type corruption reaction function model was developed. A "data to model" approach was used rather than the usual a priori approach. The general hypothesis tested was the "monkey see, monkey do" principle. The latest data on corruption among developing...

We build a robustness (RB) version of the Obstfeld (1994) model to study the effects of financial integration on growth and welfare. Our model can account for the empirically observed heterogeneity in the relationship between growth and volatility for different countries. The calibrated model...

We present a novel finding that high macroeconomic uncertainty is associated with greater accumulation of physical capital, despite a contemporaneous reduction in investment. To reconcile this evidence, we show that high uncertainty predicts a persistent decrease in the utilization and...
