Japanís prolonged ZLB period alongside substantial debt accumulation makes it a compelling laboratory for testing whether fiscal multipliers differ across normal and ZLB periods. This paper investigates this question using a sign- and zero-restricted TVP-VAR that jointly identifies fiscal rules...

This research aimed to identify existence of a New Keynesian Phillips Curve in Vietnam. The examined period was 2012Q2 - 2025Q2, using secondary macroeconomics data and the Generalised Moments Method at 95% level of confidence. The dependent variables were price inflation and wage inflation,...

The current monetary policy framework of the Fed intends to be more 'inclusive' by running the economy hot for longer during expansions. The logic of this strategy rests on Okun's (1973) hypothesis that sustaining a 'high-pressure economy' persistently improves labor market outcomes of low-wage...

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 paper analyzes the unanalized topic in macroeconomic (monetary) politics, which is the emergence of the currency crisis as a consequence of targeting inflation. Many central banks adopted inflation targeting under a pressure from the IMF. Sudden depreciation of exchange rate which results...

We use an estimated medium-scale HANK model to investigate how the tradeoff between stabilizing inflation and consumption volatility varies for households with different levels of wealth. Consumption for the rich is mostly affected by demand shocks via their exposure to highly procyclical...

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...

This paper analyzes the monetary policy trade-off between defending purchasing power of consumers and keeping moderate debt cost for borrowers, in the framework of a heterogeneous agent New Keynesian open economy hit by a foreign energy price shock. Raising the interest rate indeed combats the...

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,...

This paper estimates a New Keynesian model with heterogeneous agents to study the interactions among monetary policy, macroeconomic shocks, and the distribution of income between capital and labor. The model assumes two types of households: workers, who supply labor to firms and receive wage...

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...

We introduce an estimated medium scale Heterogeneous-Agent New Keynesian model for forecasting and policy analysis in the Euro Area and discuss the applications of this type of models in central banks, focusing on two main exercises. First, we examine an alternative scenario for monetary policy...

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...

We characterize optimal monetary policy under state-dependent pricing. The framework gives rise to nonlinear inflation dynamics: The flexibility of the price level increases after large shocks due to an endogenous rise in the frequency of price changes. In response to large cost-push shocks,...
