This paper deals with instability in regression coefficients. We propose a Bayesian regression model with time-varying coefficients (TVC) that allows to jointly estimate the degree of instability and the time-path of the coefficients. Thanks to the computational tractability of the model and to...

We propose a new approach to the study of stock returns. We develop a simple model to show that, in the long run, the average rate of return on the market portfolio equals the average growth rate of income plus an average payout rate measuring the quantity of financial resources distributed or...

We derive a canonical representation for the no-arbitrage discrete-time term structure models with both observable and unobservable state variables, popularized by Ang and Piazzesi (2003). We conduct a specification analysis based on this canonical representation and we analyze how alternative...

We propose a methodology to build and validate a composite indicator of the market liquidity of euro-area sovereign bonds. The indicator aggregates several metrics from different trading venues, with the aim of providing a comprehensive measurement of prevailing bond-market liquidity conditions...
