This paper examines the optimal path of consumption over time in the context of population ageing. Older age groups are considered to have relatively greater ‘needs’, resulting for example from additional health costs. These differences give rise to the concept of the ‘equivalent number of...

This paper estimates a lower bound to the foregone gains of incomplete portfolios, which are in turn a lower bound to the (unobserved) entry costs that could rationalize non-participation to financial markets. My estimates provide a heuristic test for the cost-based explanation of limited...

In this paper, we revisit the effects of government spending shocks on private consumption within an estimated New-Keynesian DSGE model of the euro area featuring non-Ricardian households. Employing Bayesian inference methods, we show that the presence of non- Ricardian households is in general...

I study optimal incentive contracting in a two-period model in which an agentʼs action generates an output with delay, and a noisy signal of output early. Under very general conditions, the optimal contract depends on the early signal as well as on output even if the signal is uninformative of...

We question the conventional view that it is optimal for government to maintain a stable level of spending out of oil wealth. We compare this conventional policy recommendation with one where government spends all of its oil revenues upfront, at the same rate as oil is extracted. Using a...

We derive a precautionary demand for international reserves in the presence of sovereign risk and show that political-economy considerations modify the optimal level of reserve holdings. A greater chance of opportunistic behavior by future policy makers and political corruption reduce the demand...
