Remarks at the Center for the New Economy 2010 Economic Conference, San Juan, Puerto Rico.

We provide an overview of data requirements necessary to monitor repurchase agreements (repos) and securities lending (sec lending) markets for the purposes of informing policymakers and researchers about firm-level and systemic risk. We start by explaining the functioning of these markets, and...

Some classical inference procedures can be shown to be completely robust in theses classes of multivariate distributions. These findings are used in the practically relevant context of regression models. We present a robust bayesian analysis and indicate the links between classical and Bayesian...

The paper is about the economic modelling of aggregate consumption expenditure with particular emphasis on the distribution effect of income. Under certain assumptions on the evolution over time of the population of households ("structural stability") we shall derive a first order approximation...

This paper explains how the Gibbs sampler can be used to perform Bayesian inference on GARCH models. Although the Gibbs sampler is usually based on the analytical knowledge of the full conditional posterior densities, such knowledge is not available in regression models with GARCH errors. We...

A recent influential paper (O'Connell 1998) argues that panel data evidence in favor of purchasing power parity disappears once test procedures are altered to accommodate heterogeneous cross-sectional dependence among real exchange rate innovations. We present evidence to the contrary. First, we...

Jump points in curves arise when the conditions under which data are generated change suddenly, for example because of an unplanned change in a treatment. If the size of the jump in the treatment effect exceeds the range of the error distribution then the design interval within which the jump...
