NGOs are widely perceived to raise their flag in humanitarian hot-spots with strong media presence in order to attract higher private donations. We assess this hypothesis by comparing the changes in donations between US-based NGOs with and without activities in the four countries most affected...

We apply standardized numerical techniques of stochastic optimization (Judd [1998]) to the climate change issue. The model captures the feature that the effects of uncertainty are different with different levels of agent's risk aversion. A major finding is that the effects of stochasticity...

Degradation of ecosystem services may be a major component of climate change damage, and incorporation of this factor could significantly alter the significance of uncertainty in climate-economy modeling. However, this aspect has been little investigated by economic analyses of climate change...

Carbon dioxide capture and storage (CCS) is considered to be an important option for reducing carbon dioxide (CO2) emissions. However, there are still concerns about its economic viability, especially if the risk of leakage in the storage site is taken into account. We use a real options...

As growing attention is paid to climate change adaptation as an actual policy issue, the significant meaning of climate variability in adaptation decisions is beginning to be recognized. By using a real option framework, we shed light on how climate change and climate variability affect...

We develop a simple methodology to estimate monthly aggregate supply and demand conditions from bilateral international trade data for about 180 countries and 40 years. We apply our method to measure the short-run effects of natural disasters. In line with theoretical considerations, we find...

We estimate the short-run trade effects of natural disasters using monthly trade data and data on the physical intensity of earthquakes and storms. We find large negative effects for heavily indebted poor, least developed or landlocked developing countries but only small effects for other...

In this paper, we exploit exogenous variation in navigability of the Rhine river to analyze the impact of weather-related supply shocks on economic activity in Germany. Our analysis shows that low water levels lead to transportation disruptions that cause a significant and economically...

Nanotechnologies are expected to be the dominant general purpose technology of the next decades. Their market potential is immense and especially demand side arguments will have far reaching consequences for innovations. They may occur as increased miniaturization or via building completely new...

This paper analyzes, within a regional growth model, the impact of productive governmental policy and integration on the spatial distribution of economic activity. Integration is understood as enhancing territorial cooperation between the regions, and it describes the extent to which one region...
