This paper uses fractional integration and cointegration in order to model the DM/dollar and the yen/dollar real exchange rates in terms of both monetary and real factors, more specifically real interest rate and labour productivity differentials. We find that whilst the individual series may be...

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...

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)...

Fiscal policy and public debt may be required to maintain full employment and avoid secular stagnation. This conclusion emerges from a range of different models, including OLG specifications and stock-flow consistent (post-) Keynesian models. One of the determinants of the required long-run debt...

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...

This paper makes three main points. Fiscal policy, first, may be needed in the long run to maintain full employment and avoid secular stagnation. If fiscal policy is used in this way, second, the long-run debt ratio depends (i) inversely on the rate of growth, (ii) inversely on government...

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...

This paper examines the fiscal requirements for continuous full employment. We find that (i) changes in the financial behavior of households and firms require adjustments in tax rates and public debt, (ii) the stability of the steady-state solution for public debt depends on the fiscal...
