Fundamentals News , Global Liquidity and Macroprudential Policy ∗
نویسندگان
چکیده
We study optimal macroprudential policy in a model in which unconventional shocks, in the form of news about future fundamentals and regime changes in world interest rates, interact with collateral constraints in driving the dynamics of financial crises. These shocks strengthen incentives to borrow in good times (i.e. when “good news” about future fundamentals coincide with a low-world-interest-rate regime), thereby increasing vulnerability to crises and enlarging the pecuniary externality due to the collateral constraints. Quantitatively, an optimal schedule of macroprudential debt taxes can lower the frequency and magnitude of financial crises, but the policy is complex because it features significant variation across interest-rate regimes and news realizations.

متن کاملLiquidity traps, debt relief, and macroprudential policy: a mechanism design approach∗
I present a unified framework to analyze debt relief and macroprudential policies in a liquidity trap when households have private information. I develop a model with a deleveragingdriven recession and a liquidity trap in which households differ in their impatience, which is unobservable. Ex post debt relief stimulates the economy, but anticipated debt relief encourages overborrowing ex ante, m...
متن کاملHousing Bubbles and Policy Analysis∗
This paper provides a theory of credit-driven housing bubbles in an infinite-horizon production economy. Entrepreneurs face idiosyncratic investment tax distortions and credit constraints. Housing is an illiquid asset and also serves as collateral for borrowing. A housing bubble can form because houses command a liquidity premium. The housing bubble can provide liquidity and relax credit constr...
متن کاملA Closer Look at the Short-Term Return Reversal
S returns unexplained by “fundamentals,” such as cash flow news, are more likely to reverse in the short run than those linked to fundamental news. Making novel use of analyst forecast revisions to measure cash flow news, a simple enhanced reversal strategy generates a risk-adjusted return four times the size of the standard reversal strategy. Importantly, isolating the component of past return...
متن کاملSailing through the Global Financial Storm: Brazil’s recent experience with monetary and macroprudential policies to lean against the financial cycle and deal with systemic risks
The global financial crisis of 2008–12 prompted a renewal of both analytical thinking and policy practices regarding the interaction and mutual comple mentarity between monetary and prudential regulatory policies, given the simul taneous objectives of macroeconomic and financial stability. Many of these issues were present before the global financial crisis but have been thoroughly revisited ...
