The Wrong Shape of Insurance? What Cross-Sectional Distributions Tell Us about Models of Consumption Smoothing

Cross-sectional anthropometry: what can it tell us about the health of young children?

It has become common practice in health surveys to collect anthropometric measurements from young children. These datasets comprise one-point-in-time measurements for a number of children, and are very different in character from longitudinal data such as those collected during growth monitoring. This paper explores the nature of cross-sectional data, their applications and their limitations, u...

What Do Photographs Tell Us About 3D Shape?

In this paper we consider the problem of computing the 3D shape of an unknown, arbitrarily-shaped scene from multiple color photographs taken at known but arbitrarilydistributed viewpoints. By studying the equivalence class of all 3D shapes that reproduce the input photographs, we prove the existence of a special member of this class, the maximal photo-consistent shape, that (1) can be computed...

What univariate models can tell us about multivariate macroeconomic models

A longstanding feature of macroeconomic forecasting has been that a wide variety of multivariate models have struggled to out-predict univariate representations. We seek an explanation of this feature in terms of population properties. We show that if we know the univariate properties of a time-series yt these constrain tightly both the dimensions and the predictive power of the multivariate ma...
