The effect of debt on private investment is theoretically undetermined. Indeed, according to the theory, the relation between debt and private investment can either be negative (debt overhang) or positive (accelerator effect on economic growth, hence on private investment). Our study consists in...

We propose an augmented version of the RBC model that can take into account the existence of lags in observation of demand shocks. This hypothesis seems to be a good framework to account for inventories fluctuations. We find some evidence showing the introduction of lag in observation as well as...

The aim of this paper is the identification of structural shocks which affect the dynamics of sectoral inventories, through an analysis of the forecasting error variance decomposition. This identification is achieved using the American and French time series of aggregate production, sectoral...

We show that adjustment cost models with labor supply can explain both asset returns and business cycle facts when adjustment costs penalize the changes of investment. This conclusion stands in contrast to results obtained in the literature with adjustment costs that penalize the changes of capital.

The demographic structure of a country influences economic activity. The "second dividend" modifies growth. Accordingly, in general equilibrium, the second dividend and the demographic structure are interrelated. This paper aims at assessing empirically the "second dividend" in a dynamic,...

A rising share of renewables in the energy mix push es up the average price of energy - and so does a carbon tax. However the former bolsters the accumulation of capital whereas the latter, if fully recycled, does not. Thus, in general equilibrium, the effects on growth and intertemporal welfare...

Social planners in most western countries will be facing two long-lasting challenges in the next years: energy transition and fiscal consolidation. One problem is that governments might consider that implementing an energy transition could get i n the way of achieving a fiscal consolidation. If...

This paper analyses the effects of transitory increases in government spending when public debt is used as liquidity by the private sector. Aggregate shocks are introduced into an incomplete-market economy where heterogenous, infitely-lived households face occasionally binding borrowing...

The 2007-2009 crisis has led to a return of Keynesian analyses and policies. The paper analyses the contradictions between a structural crisis, the implementation at a very large scale of Keynesian policies and the denial to undermine financial capitalism. The crisis has led the French...
