In a New Keynesian DSGE model with non-Ricardian consumers, we show that automatic stabilization according to a countercyclical spending rule following the idea of the debt brake is well suited both to steer the economy and in terms of welfare. In particular, the adjustment account set up to...

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...

In this paper, we explore the benefits from a supply-side oriented fiscal tax policy within the framework of a New Keynesian DSGE model. We show that countercyclical tax rules, which are contingent on the observed welfare gap or on the cost-push shock and levied on value added, remarkably reduce...

In a New Keynesian DSGE model with labor market frictions and liquidity-constrained consumers aggregate unemployment is likely to increase due to a non-persistent government spending shock. Furthermore, the group of asset-holding households reacts very differently from the group of...

We study optimal government spending in a business cycle model with frictional unemployment. The Ramsey optimal policy is contrasted with a reference policy which would be first best in a frictionless economy. Results are: the Ramsey policy i) implies a higher steady state ratio of government...

In this paper, we utilise the multi-country version of the NAWM to analyse the impact of globalisation on euro area macroeconomic aggregates. We provide alternative model-based definitions of globalisation associated with an increase in potential output in emerging Asia and its impact on total...

This paper sheds new light on the external and domestic dimension of China’s exchange rate policy. It presents an open economy model to analyse both dimensions of macroeconomic adjustment in China under both flexible and fixed exchange rate regimes. The model-based results indicate that...

This paper presents empirical evidence against the popular perception that macro volatility is exogenous. We obtain tax effects on macro aggregates in the stochastic neoclassical model. Taxes are shown to affect the second moment of output growth rates without affecting the first moment....

In this paper, we explore the benefits from a supply-side oriented fiscal tax policy within the framework of a New Keynesian DSGE model. We show that countercyclical tax rules, which are contingent on the observed welfare gap or alternatively on the markup shock and levied on value added, reduce...

This paper discusses fiscal policy using a DSGE model with search and matching in the labour market. Fiscal policy is effective mainly via its impact through the labour market. Although public intervention tends to crowd out private consumption, public spending also improves the matching between...
