We analyze two robust portfolio selection models, where a mean-variance investor considers possible deviations from a reference distribution of asset returns, adopting a maxmin criterion. The two models differ in the metric used to measure the distance between the reference distribution of asset...

At the turn of the century, US and euro area long-term bond yields experienced a remarkable decline and remained at historically low levels despite rising short-term rates (the so called "conundrum"). Estimating macro-finance VARs and no-arbitrage term structure models, many researchers find...

A new approach to the study of stock returns is proposed. A simple model is developed 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...

We analyze two robust portfolio selection models, where a mean-variance investor considers possible deviations from a reference distribution of asset returns, adopting a maxmin criterion. The two models differ in the metric used to measure the distance between the reference distribution of asset...

We propose a two-country no-arbitrage term-structure model to analyze the joint dynamics of bond yields, macroeconomic variables and the exchange rate. The model allows to understand how exogenous shocks to the exchange rate affect the yield curves, how bond yields co-move in different countries...
