"For United States annual data that include World War II, the estimated multiplier for temporary defense spending is 0.4–0.5 contemporaneously and 0.6-0.7 over 2 years. If the change in defense spending is "permanent" (gauged by Ramey's defense-news variable), the multipliers are higher by...

This paper analyzes the role of complexity in production on the level of output and on its rate of growth. We develop an endogenous growth model with human capital accumulation, where increased complexity could exert either a positive or a negative effect on the level of output but always a...

The Asian Development Outlook (ADO) provides growth and inflation forecasts for more than 40 economies in the region. This paper assesses the accuracy of those forecasts against actual outcomes for the years from 2008 to 2011. The World Economic Outlook (WEO) forecasts by the International...

This paper estimates the growth impact of disasters, with a focus on developing Asia and its subregions. It finds that severe disasters slow down annual growth in the Pacific island countries by between 1 and 2 percentage points on average. This should come as no surprise, given these economies'...

We derive an option-pricing formula from recursive preference and estimate rare disaster probability. The new options-pricing formula applies to far-out-of-the money put options on the stock market when disaster risk dominates, the size distribution of disasters follows a power law, and the...

This is done in relation to the benchmark of World Economic Outlook (WEO) projections by the International Monetary Fund. Amid much heterogeneity across countries and years, it has been found that ADO and WEO projections overlap quite closely. Both are inaccurate, especially during crisis years,...
