We study optimal monetary policy in an analytically tractable Heterogeneous Agent New Keynesian model with rich cross-sectional heterogeneity. Optimal policy differs from that in a representative agent model because monetary policy can affect consumption inequality by reducing both idiosyncratic...

I study the role of fiscal policy in the monetary transmission mechanism. I present a novel decomposition of the equilibrium that links the wealth effect, i.e. the revaluation of households’ financial and human wealth, to the fiscal response to monetary policy. When monetary policy has fiscal...

Does market incompleteness radically transform the properties of monetary economies? Using an analytically tractable heterogeneous agent New Keynesian (HANK) model, we show that whether incomplete markets resolve "policy paradoxes" in the representative agent New Keynesian model (RANK) depends...

This paper studies the role of wealth effects in the monetary transmission mechanism in New Keynesian models. We propose a decomposition of consumption that extends the Slutsky equation to a general equilibrium setting. Wealth effects, and their amplification in general equilibrium, explain a...

This paper presents a simple Ramsey-type model example where two infinitely-living agents have same utility function except for time preference, and shows that equilibrium is indeterminate that is to be interpreted as being non-existent. The issues regarding New Keynesian transversality...

After the centrally-planned economy ceased to exist, the process of post-socialist transformations has advanced significantly. The countries of the Central and Eastern Europe (CEE), Southern and Eastern Europe (SEE) and the Commonwealth of Independent States (CIS) have been involved since in...

We present data on debt accumulation in Australia and the United States, and tentative data on Romania, to pose the question of whether Romania might experience a credit crunch as a result of the US subprime financial crisis. We develop a model of a credit crunch in a pure credit economy with...

This paper proposes conditions for the existence and uniqueness of solutions to systems of differential equations with delays or advances in which some variables are non-predetermined. An application to the issue of optimal interest rate policy is then develop in a flexible-price model where...

Economic theory has yet to come up with a general guidance regarding the dynamic effects and welfare implications of shocks to public spending. With the aim to provide a theoretical benchmark, we analyze if a rise in private consumption following an exogenous rise in government spending is a...

Since the work of Doepke and Schneider (2006a) and Meh and Terajima (2008), we know that inflation causes major redistribution of wealth - between households and the government, between nationals and foreigners, and between households within the same country. Two types of monetary policy,...
