We formalize the Keynesian insight that aggregate demand driven by sentiments can generate output fluctuations under rational expectations. When production decisions must be made under imperfect information about demand, optimal decisions based on sentiments can generate stochastic...

This paper shows that under very general conditions, there exists a locally stable Nash equilibrium in games of strategic complements (GSC), as well as in the more general case of games with non-decreasing best response correspondences. While it is well known that in such cases a unique...

We revisit the Cournot–Bertrand debate in the light of Cournot, Edgeworth and Launhardt, tracing back to Launhardt the origin of price competition in duopoly models with constant returns to scale. Then, we discuss the formalisation of consumer utility function for differentiated products,...

As GDP is highly correlated with both entering and exiting firms, we develop a totally microfounded DSGE model with endogenous firms entry as well as exit decisions. We show that the simplifying assumption of a constant firms' death rate made by the recent literature on DSGE modelling can lead...

A growing body of empirical evidence suggests that a positive technology shock leads to a temporary decline in employment. A two-country model is used to demonstrate that the open economy dimension can enhance the ability of sticky price models to account for the evidence. The reasoning is as...

This paper investigates a rational dynamic stochastic general equilibrium model with a stockout constraint and a production chain. Our model shows that both stockout avoidance and cost shock mechanisms replicate stylised inventory facts ‐‐ production is more volatile than sales and inventory...

We study the dynamic general equilibrium of an economy where risk averse shareholders delegate the management of the firm to risk averse managers. The optimal contract has two main components: an incentive component corresponding to a non-tradable equity position and a variable 'salary'...

We describe an algorithm that is able to compute the solution of a singular linear difference system under rational expectations. The algorithm uses the Generalized Schur Factorization and is illustrated by a simple example. -- stochastic dynamic general equilibrium ; linear solution methods ;...

The recent global financial crisis has increased interest in macroeconomic models that incorporate financial linkages. Here, we compare the simulation properties of five mediumsized general equilibrium models used in Eurosystem central banks which incorporate such linkages. The financial...
