This article argues that economics is currently undergoing a fundamental shift in its method, away from neoclassical economics and into something new. Although that something new has not been fully developed, it is beginning to take form and is centered on dynamics, recursive methods and...

Research finds that firms' investment and dividend policies are distorted by irreversibility and finance constraints. Whereas the existing literature examines these features separately, this paper considers their interaction. The main theoretical result concerns the separation of the investment...

We contribute to the debate over whether forecastable stock returns reflect an unexploited profit opportunity or rationally reflect risk differentials. We test whether agents could earn excess returns by selecting stocks which have a low market price compared to an estimate of the fundamental...

Labour markets play a key role in business cycle analysis. Although a focal point of research on unemployment over the past decade, endogenous job destruction has recently fallen into disfavour, since its introduction leads to a positively sloped Beveridge curve. We show that introducing...

New Keynesian models attempt to account for economic fluctuations under nominal rigidities without modelling unemployment. They struggle to generate observed output and inflation persistence. To address these issues, recent research embeds labour search with matching frictions in a New Keynesian...

Research finds that firms' investment decisions are distorted by irreversibility and finance constraints. Whereas the existing literature examines the exects of these features separately, this paper studies their interaction. The impact of these constraints on a firm's incentive to invest is...

Aggregated (S;s) models purport to provide a structural, microfounded and statistically robust explanation of aggregate investment uctuations. In this paper I analyse these claims, present several empirical puzzles arising from the model and discuss hoe the model might be extended to account for...
