We study the transmission and distributional effects of monetary policy in an environment where consumption-saving choices reflect both precautionary motives and life-cycle considerations. Age emerges as a key state variable linking multiple dimensions of heterogeneity: young households have low...

This article shows that there is a methodological problem in the traditional IS-LM model. If production cannot be sufficiently adjusted downwards, there is no uniform interest rate that simultaneously clears the money and goods markets. An extension of the credit market in the tradition of the...

Geopolitical risk (GPR) shocks that trigger the imposition of sanctions tend to lower output and raise inflation in the sanctioned country. We develop a three-equation small open economy New Keynesian model where GPR shocks are modeled as negative productivity shocks and sanctions manifest as...

This paper studies the macroeconomic effects of a belief distortion shock—defined as the unexpected component of household inflation expectations after accounting for professional forecasts and observable fundamentals. Using survey data, U.S. macroeconomic variables, and machine-learning...

Purpose This study aims to elucidate the dynamics of monetary and fiscal policy interactions in Brazil, focusing on the impacts of positive shocks in government consumption and interest rates. By comparing rational and behavioral agent responses, it clarifies how these frameworks influence gross...

Contrary to claims in studies on financial economics, a sparse database often obscures the identification of parameters in macroeconomic models. These identification problems originate from the poorly defined mapping between a structural model and reduced-form parameters. Hence, researchers rely...

We estimate a New Keynesian model that allows endogenous transitions between a target equilibrium, with inflation fluctuating around the central bank's target and interest rates typically positive, and a low-inflation equilibrium, where the effective lower bound binds and de-anchored...

Post Keynesian Economics has shifted away and even renegade from Keynes' original research program, i.e., the Unemployment Equilibrium thesis, endogenous money and liquidity preference determination of interest rate in which money and uncertainty play a fundamental part. This paper attempts to...

Building on a New Keynesian rational expectations framework, we develop a structural empirical model that jointly determines the real exchange rate, inflation, and the nominal interest rate in a small open economy. Employing a full-information system design and estimation approach that avoids...

This paper investigates dynamic relationships between U.S. government expenditure multipliers and the economy's cyclical position from 1949 to 2018 using a Time-Varying Parameter Vector Autoregression (TVP-VAR) model. We challenge the existing literature, which predominantly relies on predefined...

Households differ in their consumption baskets and inflation rates along the wealth and income distribution. We use German data to show that subsistence consumption is a main driver of these differences: the share of subsistence consumption in overall consumption is significantly higher for...

When confronted with sectoral shocks, policymakers often resort to targeted, sector-specific taxes in an \emph{ad hoc} fashion. Based on the New Keynesian Network model, we characterize the optimal tax response to sectoral shocks: it features twice as many tax instruments as there are sectors,...

I show that in a canonical HANK model, under a balanced budget fiscal rule, the effect of a nominal interest rate peg is much larger than in a representative agent (RA) model. By contrast, under a standard fiscal rule where tax revenue responds gradually to deviations of the debt-to-GDP ratio...

What is the optimal monetary policy response to tariffs? This paper explores this question within an open-economy New Keynesian model, characterizes the macroeconomic effects of tariffs, and shows that the optimal monetary policy response is expansionary, with inflation rising above and beyond...
