This paper examines credit market policies under pecuniary externalities induced by collateral constraints. Pigouvian taxes/subsidies on debt or savings are derived as Ramsey-optimal policies. Firstly, prudential (ex-ante) debt taxes can restore constrained efficiency. Secondly, when policies...

We analyze jointly optimal carbon pricing and leverage regulation in a model with financial constraints and endogenous climate-related transition and physical risks. The socially optimal emissions tax is below the Pigouvian benchmark (equal to the direct social cost of emissions) when emissions...

We develop measures of certain kinds of liquidity trading risk that is useful for completing the definition of market risk and for predicting liquidity-adjusted VaR (L-VaR) under illiquid market conditions. We argue that asset liquidity risk associated with the uncertainty of liquidating...

We augment a standard monetary DSGE model to include a banking sector and financial markets. We fit the model to Euro Area and US data. We find that agency problems in financial contracts, liquidity constraints facing banks and shocks that alter the perception of market risk and hit financial...

In this paper, we conduct an empirical analysis of the impact of better judicial enforcement on the probability of being credit rationed, loan size, and the probability of bankruptcy using household-level data from the Japanese Panel Survey of Consumers, conducted by the Institute for Research...

We analyze the trading book of a key market maker in the European unsecured money market and study the extent to which liquidity risks accumulated by this market maker affect his pricing of liquidity and the bid/ask spread he quotes on unsecured borrowing and lending. We find that the larger the...

This paper addresses the macroeconomic impact of international financial integration. I first provide empirical evidence that foreign banking penetration can be associated with a contraction of banking credit, especially in countries with poor credit markets. Second I present a model in which...

Complex mortgages became a popular borrowing instrument during the bullish housing market of the early 2000s but vanished rapidly during the subsequent downturn. These non-traditional loans, including interest-only and negative-amortization loans, enable households to postpone loan repayment in...

We augment a standard monetary DSGE model to include a banking sector and financial markets. We fit the model to Euro Area and US data. We find that agency problems in financial contracts, liquidity constraints facing banks and shocks that alter the perception of market risk and hit financial...

In this paper, we build a heterogeneous agents-dynamic general equilibrium model wherein saving constraints interact with credit constraints. Saving constraints in the form of fixed costs to use the financial system lead households to seek informal saving instruments (cash) and result in lower...
