Optimal Policy and Taylor Rule Cross-Checking Under Parameter Uncertainty
(2013-09-26)
We examine whether the robustifying nature of Taylor rule cross-checking under model uncertainty carries over to the case of parameter uncertainty. Adjusting monetary policy based on this kind of cross-checking can improve ...
Monetary Policy Implementation in an Interbank Network: Effects on Systemic Risk
(2014-03-26)
This paper makes a conceptual contribution to the effect of monetary policy on financial stability. We develop a microfounded network model with endogenous network formation to analyze the impact of central banks' monetary ...
Mutual Excitation in Eurozone Sovereign CDS
(2014-05-01)
We study self- and cross-excitation of shocks in the Eurozone sovereign CDS market. We adopt a multivariate setting with credit default intensities driven by mutually exciting jump processes, to capture the salient features ...
Systemic Risk in an Interconnected Banking System with Endogenous Asset Markets
(2014-03-30)
We analyze the emergence of systemic risk in a network model of interconnected bank balance sheets. The model incorporates multiple sources of systemic risk, including size of financial institutions, direct exposure from ...
Exit Strategies
(2014-04-01)
We study alternative scenarios for exiting the post-crisis fiscal and monetary accommodation using a macromodel where banks choose their capital structure and are subject to runs. Under a Taylor rule, the post-crisis ...
An Experiment on Retail Payments Systems
(2014-05-05)
We study the behavioral underpinnings of adopting cash versus electronic payments in retail transactions. A novel theoretical and experimental framework is developed to primarily assess the impact of sellers’ service fees ...
Vertical Fiscal Imbalances and the Accumulation of Government Debt
(2014-07-01)
"The implications of delegating fiscal decision making power to sub-national governments has become an area of significant interest over the past two decades, in the expectation that these reforms will lead to better and ...
Idiosyncratic Risk, Aggregate Risk, and the Welfare Effects of Social Security
(2017-12-01)
We ask whether a pay-as-you-go financed social security system is welfare improving in an economy with idiosyncratic productivity and aggregate business cycle risk. We show analytically that the whole welfare benefit from ...
A Life-Cycle Model with Ambiguous Survival Beliefs
(2015-10-02)
Based on a cognitive notion of neo-additive capacities reflecting likelihood insensitivity with respect to survival chances, we construct a Choquet Bayesian learning model over the life-cycle that generates a motivational ...
Social Security in an Analytically Tractable Overlapping Generations Model with Aggregate and Idiosyncratic Risk
(2015-04-13)
When markets are incomplete, social security can partially insure against idiosyncratic and aggregate risks. We incorporate both risks into an analytically tractable model with two overlapping generations. We derive the ...
