Corruption is thought to prevent poor countries from catching up with richer ones. We analyze one channel through which corruption hampers growth : public investment can be distorted in favor of specific types of spending for which rent-seeking is easier and better concealed. To study this...

This paper investigates the relationship between private and public investment in R&D, while taking into account the effect of several instruments policies such as subsidies and taxes. We design a new look of knowledge spillovers and R&D cooperation to explain the contribution of public and...

In this paper we study an entrant's incentives to build a network infrastructure, when there is an initial phase of service-based competition where it leases access to the incumbent's infrastructure. We build a model in which the phase of service-based competition allows the entrant to step into...

We explore the consequences of bad governance and corruption for public debt and welfare in a model of policymaking with time inconsistency. A decrease in institutional quality is supposed to adversely affect government revenue. The main point of this paper is that corruption can enhance welfare...

We deal with the problem of outsourcing the debt for a big investment, according two situations: either the firm outsources both the investment (and the associated debt) and the exploitation to a private consortium, or the firm supports the debt and the investment but outsources the...

This paper studies the inflationary implications of interest bearing regional debt in a monetary union. Is this debt simply backed by future taxation with non inflationary consequences ? Or will the circulation of region debt induce monetization by a central bank ? We argue here that both...

This paper assesses the long-run optimal level of public debt in a framework where aggregate fluctuations are taken into account. Households are subject to both aggregate and idiosyncratic shocks and the market structure prevents them from perfectly insuring against risk. We find that the...

This paper analyses the effect 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, infinitely-lived households face occasionally binding borrowing...

This paper studies a simple stochastic two-period general equilibrium exchange model with money, an incomplete market of nominal assets, and a competitive banking system, intermediate between consumers and a Central Bank. There is a finite number of agents, consumers and banks. Default is not...

This article analyzes the consequences of environmental tax policy under public debt stabilization constraint. A public sector of pollution abatement is financed by a tax on pollutant emissions and/or by public debt. In the same time, households can also invest in private pollution abatement...
