This paper reviews the evidence on the effects of recessions on potential output. In contrast to the assumption in mainstream macroeconomic models that economic °uctuations do not change potential output paths, the evidence is that they do in the case of recessions. A model is proposed to...

Two fundamental problems in economic analysis concern the deter mination of aggregate output, and the determination of market prices and quantities. The way economic adjustments are made at the micro level suggests that the history of shocks to the economic environment matters. This paper...

Computer simulations of dynamical systems contain discretizations, where finite machine arithmetic replaces continuum state space. For chaotic dynamical systems, the main features of this discretization are stochastically related to the parameters both, of the underlying continuous system and of...

We introduce a probabilistic framework for hysteresis, a ubiquitous phenomenon in economic situations involving sunk costs. The framework is applied to a simple model of a firm's market entry/exit decisions. We study the influence of sunk cost size, width of the hysteretic loop, and of...

A class of heterogeneous agent models is investigated where investors switch trading position whenever their motivation to do so exceeds some critical threshold. These motivations can be psychological in nature or reflect behaviour suggested by the efficient market hypothesis (EMH). By...

John Hardman Moore outlines his joint research with Nobu Kiyotaki on the macroeconomic questions to do with the nature of money and liquidity, and the interplay between the financial system and the aggregate economy.

John Hardman Moore outlines his joint research with Oliver Hart, looking at the economics of power and control and the foundations of contractual incompleteness

This paper disaggregates a UK Input-Output (IO) table for 2004 based on household income quintiles from published survey data. In addition to the Input-Output disaggregation, the household components of a UK Income Expenditure (I-E) account used to inform a Social Accounting Matrix (SAM),have...
