We focus on the role that the transmission of information between a multilateral (e.g., the IMF) and a country has for optimal (conditional) reform design. The main result is that the informational advantage of the country must be strictly greater than the advantage of the multilateral in order...

Noting that many economic variables display occasional shifts in their second order moments, we investigate the performance of homogenous panel unit root tests in the presence of permanent volatility shifts. It is shown that in this case, panel unit root tests derived under time invariant...

We introduce a new, factor based bootstrap approach which is robust under heteroskedastic error terms for inference in functional coefficient models. Modeling the functional coefficient parametrically, the bootstrap approximation of an F statistic is shown to hold asymptotically. In simulation...
