The aim of this paper is to study the qualitative impact of short-run disequilibria on long-run positions. In this perspective, we refer to a classical framework. We underline that one sector classical growth models only deal with perfectly adjusted situations (steady-state equilibria). Such models assume that short-run dynamics are neutral in...

We analyze the impact of a credit crunch on aggregate investment via the heterogeneous structure of the banking system. We develop a model of endogenous credit allocation in which investors and two banks differ according to their level of capital and monitoring technology. In a context of moral hazard problem, we show that banks' cost advantage...

We analyze the impact of the new Internal Rate Based (IRB) Basel II capital requirements on the credit portfolio of banks and on their incentive to take risk. We show that for some initially risky banks, there is an incentive bias to finance a riskier credit bucket when they shift from Basel I to IRB Basel II capital requirements. Basel II bank...

We investigate the impact the risk sensitive regulatory ratio may have on banks' risk taking behaviours during the business cycle. We show that the risk sensitivity of capital requirements introduce by Basel II adds either an "equity surplus" or an "equity deficit" on a bank that owns a fixed capital endowment and a constant leverage ratio....

We investigate the impact the risk sensitive regulatory ratio may have on banks' risk taking behaviours according to two aspects: potential effects induced by the implementation of a risk sensitivity ratio and cyclical impacts that could affect risk taking behaviour. We show that the risk sensitivity of capital requirements introduce by Basel...

This paper investigates the incentive mechanism of individual microlending contracts focusing particularlyon microsavings. We built a model to show the role of compulsory and voluntary microsavingsin addressing problems of information asymmetries. Our results are twofold. First, we show thatcompulsory savings creates incentive conditions...

We propose a simple model of endogenous growth which puts forward the non linear impact of monetary policy on long run economic growth. Moreover, we show that, out of steady state, the volatility of inflation (expected and non-expected) decreases the rate of growth. In a stochastic framework, the precautionary saving induced by inflation...

This paper investigates the incentive mechanism of individual microlending contracts focusing particularly on microsavings. We built a model to show the role of compulsory and voluntary microsavings in addressing problems of information asymmetries. We show that voluntary savings can serve as a complementary tool in repayment enforcement at the...

In a heterogeneous financial system, we study a capital crunch transmission on total investment. We develop a model of endogenous credit allocation in which investors, small and large banks differ according to their level of capital and monitoring technology. In a context of moral hazard, imperfect substitutability between the different sources...

We examine the impact of a "near-zero" interest rate policy on bank output. Specifically, we document the existence of negative banking output on deposits for French banks from 2009. We show a structural break in banks' long run interest rate pass-through that explains this change in their business model during the 2003–2012 period. Since the...

We analyse the determinants of banks' balance-sheet and leverage-ratio dynamics and their role in increasing financial fragility. Our results are twofold. First, we show that there is a value of bank's leverage that minimises financial fragility. Second, we show that this value depends on the overall business climate, the expected value of the...
