- Abstract
- This special feature discusses the potential differences, tensions and complementarities between micro- and macro-prudential policies. It argues (i) that in spite of the frictions that may arise between them, micro- and macro-prudential policies overall complement each other, and (ii) that the two policy domains play an equally important role in ensuring financial stability. To benefit most from their complementarities, it is essential that there is constructive cooperation and information sharing between micro- and macro-supervision.

- Abstract
- The empirical literature on systemic banking crises (SBCs) has shown that SBCs are rare events that break out in the midst of credit intensive booms and bring about particularly deep and long-lasting recessions. We attempt to explain these phenomena within a dynamic general equilibrium model featuring a non-trivial banking sector. In the model, banks are heterogeneous with respect to their intermediation skills, which gives rise to an interbank market. Moral hazard and asymmetric information on this market may generate sudden interbank market freezes, SBCs, credit crunches and, ultimately, severe recessions. Simulations of a calibrated version of the model indicate that typical SBCs break out in the midst of a credit boom generated by a sequence of positive supply shocks rather than being the outcome of a big negative wealth shock. We also show that the model can account for the relative severity of recessions with SBCs and their longer duration.

- Abstract
- This paper develops a general equilibrium model to analyse the link between financial imbalances and financial crises. The model features an interbank market subject to frictions and where two equilibria may (co-)exist. The normal times equilibrium is characterized by a deep market with highly leveraged banks. The crisis times equilibrium is characterized by bank deleveraging, a market run, and a liquidity trap. Crises occur when there is too much liquidity (savings) in the economy with respect to the number of (safe) investment opportunities. In effect, the economy is shown to have a limited liquidity absorption capacity, which depends

- Abstract
- Using a unique data set on trade credit defaults among French firms, we investigate whether and how trade credit is used to relax financial constraints. We show that firms that face idiosyncratic liquidity shocks are more likely to default on trade credit, especially when the shocks are unexpected, firms have little liquidity, are likely to be credit constrained or are close to their debt capacity. We estimate that credit constrained firms pass more than one fourth of the liquidity shocks they face on to their suppliers down the trade credit chain. The evidence is consistent with the idea that firms provide liquidity insurance to each other and that this mechanism is able to alleviate the consequences of credit constraints. In addition, we show that the chain of defaults stops when it reaches firms that are large, liquid, and have access to financial markets. This suggests that liquidity is allocated from large firms with access to outside finance to small, credit constrained firms through trade credit chains.

- Abstract
- The paper presents the Dutch country block of the ESCB Multi-Country Model (MCM) for the euro area. We show how a theoretical model is translated into an econometric specification and how this specification is in turn estimated and used in the projection exercises of the E(S)CB. The dynamic properties of the model are analyzed and the effects of six exogenous shocks to the economy discussed. The long run simulations performed deliver responses of the baseline economy in line with both macroeconomic theory and practice, from a quantitative and a qualitative point of view.

- Abstract
- The purpose of this paper is to analyze how shocks propagate through a network of firms that borrow from, and lend to, each other in a trade credit chain, and to quantify the effects of financial contagion across firms. I develop a theoretical model of financial contagion, in which the default of one firm may cause a chain reaction such that its creditors also get into financial difficulties, even though they are sound in the first place. I calibrate and simulate the model using US annual data over the period 1986-2004. At the microeconomic level, I find that, when customers of a sound firm are financially distressed, then this firm gets into financial difficulties with probability that ranges from 4.1% to 12.8% (depending on the business cycle and the underlying economic scenario). Looking at the macroeconomic level, I find that defaults on trade debts lower aggregate GDP by at least 0.4%. During the second half of the 90's, these deadweight losses doubled and reached a high of 0.9% to 2.3% of GDP (depending on the underlying economic scenario) before the recession of 2001. The results of the simulations also suggest that financial contagion across businesses had been 25% higher during the last recession than during the recession of the early 90's.

- Abstract
- This paper presents the French country block of the ESCB Multi-Country Model for the euro area, which has been built in collaboration by the ECB and the Banque de France. The theoretical structure of the model is in line with most current macroeconometric models, i.e. supply factors determine the long-run equilibrium, while in the short run aggregate demand determines aggregate output. The paper is structured as follows. We first present the theoretical background of the model. Then we review the long run relationships as well as the estimated short term dynamic equations. Finally, we simulate the effects of six exogenous shocks to the economy and discuss the dynamic properties of the model.

- Abstract
- The cost-of-financing channel version of the financial accelerator proposed by Bernanke & Gertler [1989] is prominent in the literature. Yet, this particular channel has not been validated by empirical work. This paper presents an alternative version of the accelerator. This new accelerator, based on quantity credit rationing, is shown to be more powerful than the traditional accelerator. By causing factor under-utilization credit rationing generates an output gap persistent and sensitive to technology shocks. This accelerator is not a substitute to the traditional mechanism though, but rather a complement. My model helps improve the understanding of financial transmission mechanisms. It considers several types of collaterals. Financial frictions generate persistence when collaterals take the form of tangible assets. They generate amplification when collaterals take the form of cash flows or when asset prices are variable.
