The efficiency of market-determined risk classification in automobile insurance is a lasting matter of controversy. It can be traced back to the 1950s (Muir, 1957) and received broad economic attention in the 1980s when spiralling car insurance premiums in the US were blamed on tariff...

Banks operating under Value-at-Risk constraints give rise to a welldefined aggregate balance sheet capacity for the banking sector as a whole that depends on total bank capital. Equilibrium risk and market risk premiums can be solved in closed form as functions of aggregate bank capital. We...

This paper contains a general equilibrium model of an economy with incomplete markets (GEI) with money and default. The model is a simplified version of the real world consisting of a non-bank private sector, banks, a central bank, a government and a regulator. The model is used to analyse...

We develop a search-based model of asset trading, in which investors of different horizons can invest in two identical assets. The asset markets are partially segmented: buyers can search for only one asset, but can decide which one. We show that there exists a "clientele" equilibrium where one...

The most striking difference in corporate-governance arrangements between rich and poor countries is that the latter rely much more heavily on the dynastic family firm, where ownership and control are passed on from one generation to the other. We argue that if the heir to the family firm has no...

The non-negativity constraint on inventories imposed on the rational expectations theory of speculative storage implies that the conditional mean and variance of commodity prices are non-linear in lagged prices and have a kink at a threshold point. In this paper, the structural parameters of...

We propose a dynamic equilibrium model of a multi-asset market with stochastic volatility and transaction costs. Our key assumption is that investors are fund managers, subject to withdrawals when fund performance falls below a threshold. This generates a preference for liquidity that is...

This paper analyses whether sovereign default episodes can be seen as contingencies of optimal international lending contracts. The model considers a small open economy with capital accumulation and without commitment to repay debt. Taking first order approximations of Bellman equations, I...

Sometimes regulators become experimenters: they try ideas out before implementing them, put novel schemes to the test in order to predict their likely impact, or conduct pilot programmes before executing new policies. Regulators find experiments very expedient, as they allow them to forecast the...

The purpose of our work is to explore contagious financial crises. To this end, we use simplified, thus numerically solvable, versions of our general model [Goodhart, Sunirand and Tsomocos (2003)]. The model incorporates heterogeneous agents, banks and endogenous default, thus allowing various...
