Keynes' principle of effective demand constitutes a pillar for Post Keynesians theories. But Keynes' presentation remains difficult to interpret, mainly because the aggregate demand function is based on entrepreneurs' expectations. The problem is then to demonstrate how these entrepreneurs...

The fiscal theory of the price level says that the price level can be made determinate if the government uses fiscal policies such that government liabilities explode unless the price in the first period is at the "right" level. The policy implications are disturbing, as they call for rather...

This paper offers a framework to study commitment and cooperation issues in games with multiple policymakers. To reconcile some puzzles in the recent literature on the nature of policy interactions among nations, we prove that games characterized by different commitment and cooperation schemes...

The paper presents both the New Consensus and Keynesian equilibrium within the usual fourcompetitive macro-markets structure. It gives theoretical explanations of the perniciouseffects that the NCM governance, which has been designed for ergodic stationary regimes,brings about in Keynesian...

The paper studies the effects of heterogeneity upon the monetary and fiscal-budgetary policy interactions in a Keynesian monetary union. As a result of interactions, some of our results contrast sharply with the ones in studies that consider separately monetary, fiscal and budgetary policies....

Because it was designed for efficient stationary regimes, the New-Consensus Macroeconomic governance carries several drawbacks when implemented in Keynesian non-ergodic regimes. As long as Keynesian unemployment is interpreted in terms of 'natural' rate, it serves as a macroeconomic policy...

Extending Asensio's closed-economy framework (2005a,b) to a monetary union, we show that theprinciples of governance which emanate from the so called "New Consensus in Macroeconomics"(NCM), and therefore have been designed for presumed stationary regimes, may cause severedysfunctions, such as...

In this paper, we study maximizing long-run economic growth trade-off in monetary and fiscal policies in an endogenous growth model with transaction costs. We show that both monetary and fiscal policies are subject to threshold effects, a result that gives account of a number of recent empirical...
