We present a simple model where bank runs are possible and we analyse the role of subsidization of future investment in this setting. We find that such a policy exacerbates the short-run liquidity problem for banks. Moreover, we highlight that a ‘shift in expectations’ about the keeping of...

A simple dynamic general-equilibrium model of savings and investment is populated by agents with Kreps-Porteus preferences. Households are heterogeneous in their risk aversion, which explains the negative relationship between aggregate investment and aggregate volatility. Agents trade riskless...

In a beauty contest framework, we show that a more precise public information is welfare enhancing when increasing the precision of private information is costly. The accuracy of public information is chosen by the public authority taking into account that an increase in the precision of public...

We develop a dynamic duopoly, in which firms have to take into account a technological externality, which reduces their innovation costs over time, and an inter-firm spillover, which lowers only the second comer’s R&D costs. This spillover exerts its effect after a disclosure lag. We identify...

We study the welfare implications of public information precision in a beauty contest framework allowing for optimal stabilization policies and information obfuscation. When policy makers’ ability to obfuscate information is constrained, increasing public information precision can be welfare...

We study information acquisition in a exible framework with strategic complementarity or substitutability in actions and a rich set of externalities that are responsible for possible wedges between the equilibrium and the efficient acquisition of information. First, we relate the (in)efficiency...

In this paper, we highlight the possibility of dynamically inefficient equilibria in a model with strictly convex production function at the firm’s level. Decreasing returns imply the existence of some pure profit and hence of an asset market. We endogenise the number of firms by introducing a...

In a recent article Hosoda analyzes the relation between per capita consumption and growth rate in a Sraffian scheme where capitalists and workers have different patterns of consumption. He claims that this relation can be increasing and that this "anomaly does not disappear even if we choose...
