We study optimal monetary policy in an analytically tractable heterogeneous agent New Keynesian model with rich cross-sectional heterogeneity. Optimal differs from a representative benchmark because can affect consumption inequality, by stabilizing risk arising both idiosyncratic shocks and unequal exposures to aggregate shocks. The trade-off between productive efficiency, price stability is su...

We document heterogeneity in the marginal propensity to consume (MPC) across household characteristics relevant understanding heterogeneous agent models and monetary policy transmission. find a strong negative relationship between liquid wealth MPC. show that predicts MPC closely for every other characteristic we look at. use new empirical method overcomes sources of bias found existing literat...

Commonly used instruments for the identification of monetary policy disturbances are likely to combine true shock with information about state economy due disclosed through action. We show that this signaling effect can give rise empirical puzzles reported in literature, and propose a new high-frequency instrument shocks accounts informational rigidities. find tightening is unequivocally contra...

Pfanzagl and Wefelmeyer (1978) show that bias corrected ML estimators are higher order efficient. Their procedure however is computationally complicated because it requires integrating complicated functions over the distribution of the MLE estimator. The purpose of this paper is to show that these integrals can be replaced by sample averages without affecting the higher-order variance. We focus...

Willingness to pay for air quality is a function of health and the costly defensive investments that contribute to health, but there is little research assessing the empirical importance of defensive investments. The setting for this paper is a large US emissions cap and trade market – the NOx Budget Trading Program (NBP) – that has greatly reduced NOx emissions since its initiation in 2003. Us...

Trading frictions in financial markets affect more long-term than short-term bonds, generating an upward-sloping yield curve. Long-term financing is expensive economies with higher trading so firms choose to borrow and invest shorter horizons lower productivity projects. The theory guides a new identification of the slope liquidity spread data. We measure calibrate model for United States, coun...

This paper considers an application of the Markov switching vector error correction model to analysis long-run and short-run dependence Russian real GDP exchange on oil prices. An algorithm for estimation with a priori information state hidden chain in some periods time is provided. It shown that period 1999–2018 two different regimes are well defined: slow adjustment rate sharp reaction respon...

The challenge for stabilization policy presented by the COVID-19 pandemic stems above all from disruption of circular flow payments, resulting in a failure what Keynes (1936) calls “effective demand.” As consequence, economic activity many sectors can be inefficiently low, and interest-rate cannot eliminate distortions—not because limit on extent to which interest rates reduced, but reductions ...

We study optimal time-consistent monetary and fiscal policy in a New Keynesian model where occasional declines agents’ confidence give rise to persistent liquidity trap episodes. Insights from widely studied fundamental-driven traps are not useful guide for enhancing welfare this model. Raising the inflation target, appointing an inflation-conservative central banker, or allowing use of governm...
