Tests for long-run purchasing power parity (PPP) may lack power with sample periods corresponding to the span of the recent float, leading researchers to use more powerful multivariate unit root tests. We point out a potential problem with such tests: joint non-stationarity of real exchange...

The drift-adjustment method estimates the expected rate of depreciation within an exchange rate band by simple equations. Papers applying this method claim that, while forecasting a freely floating currency is hopeless, predicting an exchange rate within the future band is successful. This paper...

Private pension provision faces the challenging task of providing stable income streams during retirement. The challenge has increased markedly in the last decades due to volatile financial markets, falling interest rates and the withdrawal of employers and external insurers as risk bearers of...

Despite much work on hedging in incomplete markets, the literature still lacks tractable dynamic hedges in plausible environments. In this article, we provide a simple solution to this problem in a general incomplete-market economy in which a hedger, guided by the traditional minimum-variance...

Financial crises are associated with reduced volumes and extreme levels of rates for term inter-bank transactions, such as in one-month and three-month LIBOR markets. We provide an explanation of such stress in term lending by modelling leveraged banks’ precautionary demand for liquidity. When...

We develop a dynamic model of investment, cash holdings, financing, and risk management policies in which firms face financing frictions and are subject to permanent and temporary cash flow shocks. In this model, target cash holdings depend on the long-term prospects of the firm, implying that...

This article introduces a method to quantify the effect of a firm’s strategic choices on the risk profile of its profits at different horizons. We combine a demand system for differentiated products with counterfactual paths of risk factors. Prices, costs and quantities respond endogenously to...

We study three cases in which specialized arbitrageurs lost significant amounts of capital and, as a result, became liquidity demanders rather than providers. The effects on security markets were large and persistent: Prices dropped relative to fundamentals and the rebound took months. While...

We investigate the question of whether sophistication in risk management fosters banking stability. We compare a simple banking system in which an average rating is used with a sophisticated banking system in which banks are able to assess the default risk of entrepreneurs individually. Both...

We analyse the demand for hedging and insurance by a firm that faces liquidity risk. The firm's optimal liquidity management policy consists of accumulating reserves up to a threshold and distributing dividends to its shareholders whenever its reserves exceed this threshold. We study how this...
