The paper focuses on the interactions between investment and non-cooperative wage bargaining when the investment decision of the firm bears irreversibly both on the size of the productive capacity and on the capital intensity of the technology used by the firm. The paper first shows how a given...

We survey the issue of environmental limits to growth in macroeconomic theory. We first analyse to what extent economic growth may be constrained in a world with finite natural resources. We next cover the topic of growth-induced environmental degradation. For both themes, we present the...

We reassess the issue of limits to growth in an endogenous growth model of a decentralized economy where final productions require a recyclable essential material input. The model relies on technological assumptions consistent with the material balance principle and on an explicit distinction...

We analyse the transition of a decentralized economy whose energy supply switches progressively from non-renewable (NRE) to renewable energy (RE) sources. The two energies are perfect substitutes but RE production offers a lower Energy Return On Energy Invested(EROEI). The transition is...

We introduce the concept of carbon footprint into an aggregate demand and supply model with imperfectly competitive price and wage formation. We analyse the properties of the short-term macroeconomic equilibrium in the presence of a climate policy, which may take the form either of a carbon tax...

Nous introduisons le concept d'empreinte carbone dans un mod èle o ffre globale et demande globale avec formation imparfaitement concurrentielle des prix et salaires et en examinons les propriétés de l' équilibre en présence d'une politique climatique. Nous étudions deux instruments...

We study the consequences of a working time reduction (WTR hereafter) in an exogenous growth model with unemployment (due to efficiency wage considerations) and a renewable natural resource. The resource is an essential input whose marginal productivity is bounded by physical laws. In the...

We study the consequences of a working time reduction (WTR hereafter) in a growth model with efficiency wages and an essential natural resource (natural capital). Considering that technical progress cannot reduce the resource content of final production to zero, we show that the effects of a WTR...
