We study the impact of global climate change on the prevalence of tropical diseases using a heterogeneous agent dynamic general equilibrium model. In our framework, households can take actions (e.g., purchasing bednets or other goods) that provide partial protection from disease. However, these...

We investigate the macroeconomic effects of government spending shocks in Korea. We compare results obtained with two alternative approaches: the narrative approach and Structural Vector-Autoregressive model (SVAR). We propose a new methodology for identifying exogenous and unexpected fiscal...

Ramey (2011a) and others argue that increases in government spending associated with wars and military build-ups constitute a good instrument for measuring the macroeconomic effects of fiscal shocks. We argue that this instrument has two important drawbacks: the composition of government...

Fiscal policy has become quite controversial in the post-Keynesian era, the debate over the Obama stimulus package being a contentious recent example. Some pundits go so far as to take the position that macroeconomic theory has failed to meaningfully progress in terms of providing useful...

We investigate the short-term effects of fiscal adjustment on economic activity in 20 OECD countries from 1970 to 2009. We compare two approaches: the traditional approach based on changes in cyclically adjusted primary balance (CAPB) and the narrative approach based on historical records....

This paper undertakes a normative investigation of the quantitative properties of optimal tax smoothing in a business cycle model with state contingent debt, capital-skill complementarity, endogenous skill formation and stochastic shocks to public consumption as well as total factor and capital...

The ‘saving for a rainy day’ hypothesis implies that households’ saving decisions reflect that they can (rationally) predict future income declines. The empirical relevance of this hypothesis plays a key role in discussions of fiscal policy multipliers and it holds under the null that the...

Slower growth of the labour force and an increase in old-age dependency will reduce the growth of aggregate output and output per capita in many developed countries. However, a major question is whether there is any systematic link between demographics and the productivity of those who will...

This paper explored the determinants of survival in a life and death situation created by an external and unpredictable shock. We are interested to see whether pro-social behaviour matters in such extreme situations. We therefore focus on the sinking of the RMS Titanic as a quasi-natural...

In public good games, voluntary contributions tend to start off high and decline as the game is repeated. If high contributors are matched, however, contributions tend to stay high. We propose a formalization predicting that high contributors will self-select into groups committed to charitable...
