Our purpose in this paper is to present a class of convex endogenous growth models, and to analyze their performance in terms of both growth and business cycle criteria. The models we study have close analogs in the real business cycle literature. In fact, we interpret the exogenous growth rate...

We study a one-sector growth model which is standard except for the presence of an externality in the production function. The set of competitive equilibria is large. It includes constant equilibria, sunspot equilibria, cyclical and chaotic equilibria, and equilibria with deterministic or...

We construct a rational expectations model in which aggregate growth alternates between a low growth and a high growth state. When all agents expect growth to be slow, the returns on investment are low, and little investment takes place. This slows growth and confirms the prediction that the...

This paper discusses recent theoretical and empirical work on the interactions between growth and business cycles. One may distinguish two very different types of approaches to the problem of the influence of macroeconomic fluctuations on long-run growth. In the first type of approach, which...

This paper discusses the consequences of introducing imperfectly competitive product markets into an otherwise standard neoclassical growth model. We pay particular attention to the consequences of imperfect competition for the explanation of fluctuations in aggregate economic activity. Market...

We introduce a form of downward nominal wage rigidity that can vary in intensity across a continuum of labor varieties. The model delivers a static wage Phillips curve linking current wage inflation to current unemployment. For standard parameterizations, the dynamics of the model are...

We develop a perturbational technique to approximate equilibria of a wide class of discrete-time dynamic stochastic general equilibrium heterogeneous-agent models with complex state spaces, including multi-dimensional distributions of endogenous variables. We show that approximating policy...

We develop a model of self-fulfilling default cycles with demand externality a la Dixit- Stiglitz to explain the recurrent clustered defaults observed in the data. The literature reports that observable fundamental factors alone are insufficient to explain the cluster. A decline in aggregate...

This paper examines the role of lumpy consumer durables and market power in generating endogenous cycles which seem to be consistent with the facts. When goods are durable, past consumption choices determine the current market size which consists of consumers who have not purchased the good...

A small, structural model of the monetary business cycle implies that real money balances enter into a correctly-specified, forward-looking IS curve if and only if they enter into a correctly-specified, forward-looking Phillips curve. The model also implies that empirical measures of real...
