The common VAT system adopted by EU member states comprises a set of various rates, which differentiate the goods and services subject to this tax. However, from a technical and management point of view, it would be preferable to adopt a single tax rate as it reduces distortions and facilitates...

We characterise optimal tax policies when the government has access to consumption taxation and cannot credibly commit to future policies. We consider a neoclassical economy where factor income taxation is distortionary within the period, due to endogenous labour and capital utilisation and...

This paper evaluates the temporary VAT reduction invoked by the German government over the third and fourth quarter of 2020 as part of the COVID-19 stimulus package. There is considerable controversy. Critics argue that VAT reductions are ineffective in the presence of lockdown measures in place...

The following study identifies five periods with different price regimes (for main hydrocarbons): 1) 1986-1996, where these prices are part of the Government's fiscal policy to finance part of the structural adjustment policies after the inflationary period; 2) 19971999, when a new methodology...

This paper evaluates the temporary VAT reduction introduced by the German government over the third and fourth quarter of 2020 as most controversial part of the COVID-19 stimulus package. Critics argue that VAT reductions are ineffective because of limited pass-through of temporary measures to...

We use a quantitative heterogeneous agent model with nominal rigidities and unemployment risk to analyze the effectiveness of several fiscal policies in stabilizing a demand-driven recession. The model delivers empirically realistic distributions of marginal propensities to consume (mpc) and...

This paper examines the role of fiscal policy in the long run. We show that (i) dynamic inefficiency may be empirically relevant in a modified Diamond OLG model with imperfect competition, (ii) fiscal policy may be needed to avoid inefficiency (if investment adjusts passively to saving) and...

We show that (i) dynamic inefficiency may be empirically relevant in a modified Diamond model with imperfect competition, (ii) if fiscal policy is used to avoid inefficiency and maintain an optimal capital intensity, the required debt ratio will be inversely related to the growth rate, and (iii)...

This paper examines the role of fiscal policy in the long run. We show that (i) dynamic inefficiency in a standard OLG model generates aggregate demand problems in a Keynesian setting, (ii) fiscal policy can be used to achieve full-employment growth, (iii) the required debt ratio is inversely...

Fiscal policy is needed to avoid dynamic inefficiency and maintain full employment in a modified Diamond OLG model with imperfect competition. A distributionally neutral tax scheme can maintain full employment in the face of variations in household confidence. No variations in taxes will be...
