A recent theoretical literature highlights the role of endogenous firm entry as an internal amplification mechanism of business cycle fluctuations. The amplification mechanism works through the competition and the variety effect. This paper tests the significance of this amplification mechanism,...

This paper explores and quantifies the role of endogenous firm entry in amplifying and propagating shocks to the economy. To this end, we estimate two DSGE models on US data with Bayesian methods: one model with endogenous firm entry and translog preferences and one model without. Both models...

This paper explores different fiscal stimuli within a business cycle model with an endogenous number of firms. We demonstrate that a changing number of firms is a crucial dimension for evaluating fiscal policy since it accelerates the impacts of fiscal policy. In the presence of demand stimuli...

Using VAR analysis on US data, we show that unanticipated fiscal expansions boost private consumption and business formation. Models with an extensive investment margin, i.e. endogenous firm and product entry, have difficulties explaining these two phenomena simultaneously. Considering different...

This paper studies optimal taxation in a general equilibrium macro model with endogenous entry. We compare the constant elasticity of substitution (CES) model to three alternative demand structures: oligopolistic competition in prices, oligopolistic competition in quantities, and translog...
