In a model where a variable Y[sub t] is proportional to the present value, with constant discount rate, of expected future values of a variable y[sub t] the quot;spreadquot; S[sub t]= Y[sub t] - [theta sub t] will be stationary for some [theta] whether or not y[sub t]must be differenced to...

This paper investigates the possibility, raised by Perron (1989, 1990a), that aggregate economic time series can be characterized as being stationary around broken trend lines. Unlike Perron, we treat the break date as unknown a priori. Asymptotic distributions are developed for recursive,...

In this paper we examine temporal properties of eleven natural resource real price series from 1870-1990 by employing a Lagrangian Multiplier unit root test that allows for two endogenously determined structural breaks with and without a quadratic trend. Contrary to previous research, we find...

We model the equilibrium price and quantity of risk transfer between firms and financial intermediaries. Value-maximizing firms have downward sloping demands to cede risk, while intermediaries, who assume risk, provide less-than-fully-elastic supply. We show that equilibrium required returns...

This paper examines the market for catastrophe event risk i.e., financial claims that are linked to losses associated with natural hazards, such as hurricanes and earthquakes. Risk management theory suggests protection by insurers and other corporations against the largest cat events is most...

Using a unique dataset of insurance decisions by over 1,800 large U.S. corporations, this study provides the first empirical analysis of firm behavior that compares corporate demand for property and catastrophe insurance (here, terrorism). We combine demand and supply data and apply a...

This paper examines the market for catastrophe event risk i.e., financial claims that are linked to losses associated with natural hazards, such as hurricanes and earthquakes. Risk management theory suggests protection by insurers and other corporations against the largest cat events is most...

A principal reason that losses from catastrophic risks have been increasing over time is that more individuals and firms are locating in harm's way while not taking appropriate protective measures. Several behavioural biases lead decision-makers not to invest in adaptation measures until after...

This paper examines the market for catastrophe event risk -- i.e., financial claims that are linked to losses associated with natural hazards, such as hurricanes and earthquakes. This market is in transition as new approaches for transferring risk are being explored. The paper studies several...

Financial instruments whose payoffs are linked to exogenous events, such as the occurrence of a natural catastrophe or an unusual weather pattern depend crucially on actuarial models for determining event (e.g., default) probabilities. In many instances, investors appear to receive premiums far...
