In the context of interest rate derivatives, we present two simple cases of replication error associated with common hedging strategies when agents have partial information about the real dynamics of the underlying asset. In particular, we derive an explicit expression for the hedging error due...

Time-varying volatility is common in macroeconomic data and has been incorporated into macroeconomic models in recent work. Dynamic panel data models have become increasingly popular in macroeconomics to study common relationships across countries or regions. This paper estimates dynamic panel...

We consider a class of infinite‐horizon dynamic Markov economic models in which the parameters of utility function, production function, and transition equations change over time. In such models, the optimal value and decision functions are time‐inhomogeneous: they depend not only on state...
