The Review of Economic Studies is one of the core journals in economics. It is essential reading for economists, consistently ranking among the top five journals.

The structure of the Social Security program presents a trade-off between benefit duration and size; individuals who claim early receive lower monthly payments. Surprisingly, even wealthy Americans with high life expectancies frequently claim benefits at the earliest eligibility age, a behavior inconsistent with conventional life-cycle theory predictions.

Over the past four decades, the U.S. economy has seen a decline in the share of young firms alongside a rise in the profit share of GDP. This paper explores how population aging contributes to these twin trends through a demand-side channel. The core hypothesis is that younger households exhibit lower consumer inertia—a tendency to stick with previously chosen products—than older households.

We present a flexible and scalable computational framework integrating machine learning and optimization theory to solve dynamic adverse selection models with persistent private information and many types. Our approach reformulates the model into a numerically tractable structure that bypasses set-valued dynamic programming; we formally prove that, under verifiable conditions, this relaxation yields the solution to the original problem.

Even as global oil demand has increased in recent years, it is plausible to envision scenarios in which clean energy technologies or climate policies drive demand to essentially zero by the century’s end. This paper asks what such a demand decline, when anticipated, might mean for global oil supply. One possibility is a “green paradox”: producers accelerate extraction.

Standard New Keynesian (NK) models feature an optimal inflation target well below 2 percent, limited welfare losses from business cycle fluctuations and long-term monetary neutrality. We develop a NK framework with endogenous productivity and downward nominal wage rigidity (DNWR) which challenges these results.

We use a sufficient statistic approach to quantify the general equilibrium effects of population aging on the returns to wealth, wealth accumulation, and global imbalances. Combining population forecasts with household survey data from 25 countries, we measure the compositional effect of aging: how a changing age distribution affects wealth-to-GDP, holding the age profiles of wealth and labor income fixed.
