|October 2019||Optimal Policy for Macro-Financial Stability|
with , , , : w26397
There is a new and now extensive literature analyzing government policies for financial stability based on models with endogenous borrowing constraints. These normative analyses often build upon the concept of constrained efficient allocation, where the social planner is constrained by the same borrowing limit that agents face. In this paper, we show that the same set of policy tools that implement the constrained efficient allocation can be used optimally by a Ramsey planner to replicate the unconstrained allocation, thus achieving higher welfare. We establish this in the context of a well-known model economy, but the result is relevant whenever the policy instrument that is assigned to the planner can affect the market price that determines the value of collateral in the borrowing constr...
|May 2016||Optimal Capital Controls and Real Exchange Rate Policies: A Pecuniary Externality Perspective|
with , , , : w22224
A new theoretical literature studies the use of capital controls to prevent financial crises in models in which pecuniary externalities justify government intervention. Within the same theoretical framework, we show that when ex-post policies such as defending the exchange rate can contain or resolve financial crises, there is no need to intervene ex-ante with capital controls. On the other hand, if crises management policies entail some efficiency costs, then crises prevention policies become part of the optimal policy mix. In the standard model economy used in the literature with costly crisis management policies, the optimal policy mix combines capital controls in tranquil times with support for the real exchange rate to limit its depreciation during crises times. The optimal policy mix...
