The concept of a market portfolio plays an important role in many financial theories and models. Knowledge of each asset's share of the invested capital markets is both useful information and a good starting point for investors considering the appropriate allocation to the asset. In our latest...

On October 24, 2003, SUERF celebrated its 40th anniversary in the Galerie Dorée of the Banque de France with an especially high level and rich seminar. The memorable occasion was further elevated by Jean Claude Trichet giving the tenth SUERF Annual Lecture in his last public speech as Governor...

We study the transmission of liquidity shocks from one sector of the economy to other sectors in a general equilibrium model with multiple trading venues connected by profit-seeking arbitrageurs. Arbitrageurs effectively provide liquidity to investors by inter-mediating trades between venues....

The classic Arrow-Debreu framework requires a very large number of specific securities to reach Pareto optimality. The present paper shows that financial intermediation can play an important role in maintaining a more parsimonious market framework while still obtaining Pareto optimality. In the...

This paper studies the welfare properties of competitive equilibria in an economy with incomplete markets subject to idiosyncratic and aggregate shocks. We focus on the role of securitization, whereby borrowers can reduce idiosyncratic asset risk, which enables increased leverage and investment....

In a framework closely related to Diamond and Rajan (2001) we characterize different financial systems and analyze the welfare implications of different LOLR-policies in these financial systems. We show that in a bank-dominated financial system it is less likely that a LOLR-policy that follows...

The urgency of estimating the impact of climate risks on the financial system is increasingly recognized among scholars and practitioners. By adopting a network approach to financial dependencies, we look at how climate policy risk might propagate through the financial system. We develop a...

The traditional model of bank-led financial intermediation, where banks issue demandable deposits to savers and make informationally sensitive loans to borrowers, has seen a dramatic decline since 1970s. Instead, private credit is increasingly intermediated through arms-length transactions, such...

In 2008, AIG found itself on the brink of failure and required the Federal Reserve to step in with billions of dollars of taxpayer money. The causes of AIG's collapse have been described in numerous articles and official reports since then. Albeit some nuances, all analyzes point to AIG's credit...
