We present a hybrid Heston model with a local stochastic volatility to describe government bond yield dynamics. The model is analytically tractable and, therefore, can be efficiently estimated using the maximum likelihood approach. Twofold is the model contribution. First, it captures changes in...

Beginning in 2009, in many advanced economies, policy rates reached their zero lower bound (ZLB). Almost at the same time, oil prices started rising again. We analyze how the ZLB affects the propagation of oil shocks. As these shocks move inflation and output in opposite directions, their...

This paper questions unconventional fiscal policy effects when the monetary policy rate is at the zero lower bound. We provide evidence for the US that the spread between the policy rate and the US-LIBOR, which is more relevant for private sector transactions, increases with government...
