We study the implications of increased price flexibility on aggregate output volatility in a dynamic stochastic general equilibrium (DSGE) model. First, using a simplified version of the model, we show analytically that the results depend on the shocks driving the economy and the systematic...

This paper examines the role of external shocks in explaining macroeconomic fluctuations in African countries. We construct a quantitative, stochastic, dynamic, multi-sector equilibrium model of a small open economy calibrated to represent a typical African economy. In our framework, external...

We show diverse beliefs is an important propagation mechanism of fluctuations, money non neutrality and efficacy of monetary policy. Since expectations affect demand, our theory shows economic fluctuations are mostly driven by varying demand not supply shocks. Using a competitive model with...

We consider a Keynes-Goodwin model of effective demand and the distributive cycle where workers purchase goods and houses with marginal propensity significantly larger than one. They therefore need credit, supplied from asset holders, and have to pay interest on their outstanding debt. In this...

This paper introduces staggered right-to-manage wage bargaining into a New Keynesian business cycle model. Our key result is that the model is able to generate persistent responses in output, inflation, and total labor input to both neutral technology and monetary policy shocks. Furthermore, we...

The KMG growth dynamics in Chiarella and Flaschel (2000) assume that wages, prices and quantities adjust sluggishly to disequilibria in labor and goods markets. This paper modifies the KMG model by introducing Steindlian features of capital accumulation and income distribution. The resulting...

I build a Heterogeneous Agents New Keynesian model with rich labor market dynamics. Workers search both off- and on-the-job, giving rise to a job ladder, where employed workers slowly move toward more productive and better paying jobs through job-to-job transitions, while negative shocks...

This paper examines the impact of unemployment insurance on the propagation of monetary disturbances in a staggered price model of the business cycle. To motivate a role for risk sharing behavior, I construct a quantitative equilibrium model that gives prominence to an efficiency-wage theory of...

Making inferences about aggregate business cycles from regional variation alone is difficult because of economic channels and shocks that differ between regional and aggregate economies. However, we argue that regional business cycles contain valuable information that can help discipline models...

Using sectoral data at a medium level of aggregation, we find that price changes became less responsive to aggregate unemployment around 2009–2010. The slopes of the disaggregated Phillips curves diminished in many sectors, including housing and some services. We also document a decrease in...
