Around the turn of the Twentieth century, US and euro area long-term bond yields experienced a remarkable decline and remained at historically low levels even in the face of rising short-term rates (the so called "conundrum"). This unusual phenomenon has been analyzed by many researchers through...

We introduce a two-country no-arbitrage term-structure model to analyse 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...

In recent years, US and euro area long-term bond yields experienced a remarkable decline and remained at historically low levels even in the face of rising short-term rates. This unusual phenomenon (the so called ”conundrum”) has been the subject of numerous debates and extensive research....
