We study the dynamics of a Lucas-tree model with finitely lived agents who 'learn from experience.' Individuals update expectations by Bayesian learning based on observations from their own lifetimes. In this model, the stock price exhibits stochastic boom-and-bust fluctuations around the...

We present a general equilibrium model of the global oil market, in which the oil price, oil production, and consumption, are jointly determined as outcomes of the optimizing decisions of oil importers and oil exporters. On the supply side the oil market is modelled as a dominant firm – Saudi...

We postulate a nonlinear DSGE model with a financial sector and heterogeneous households. In our model, the interaction between the supply of bonds by the financial sector and the precautionary demand for bonds by households produces significant endogenous aggregate risk. This risk induces an...

We characterize the optimal debt-maturity management problem of a government in a small open economy. The government issues a continuum of finite-maturity bonds in the presence of liquidity frictions. We find that the solution can be decentralized: the optimal issuance of a bond of a given...

This paper analyzes the problem of a benevolent planner wishing to control a population of heterogeneous agents subject to idiosyncratic shocks. This is equivalent to a deterministic control problem in which the state variable is the cross-sectional distribution. We show how, in continuous time,...

The aim of this paper is to analyse the impact of the so-called "shale oil revolution" on oil prices and economic growth. We employ a general equilibrium model of the world oil market in which Saudi Arabia is the dominant firm, with the rest of the producers as a competitive fringe. Our results...

We investigate the trade-offs between price stability and the sustainability of sovereign debt, using a small open economy model where the government issues nominal defaultable debt and chooses fiscal and monetary policy under discretion. Inflation reduces the real value of outstanding debt,...

Housing prices diverge from construction prices after 1997 in four major countries. Besides, TFP differences between construction and the general economy account for the evolution of construction prices in the U.S. and Germany, but not in the U.K. and Spain

This paper analyzes the Spanish monetary system from 1856, when the Bank of Spain was created, to 1874, when it was awarded the monopoly of emission. This period was characterized by the emergence of an unregulated banking system, with multiple banks of issue entitled to emit bank notes. We...

How much should be spent in research and development (R&D)? How should R&D vary over the business cycle? In this paper we answer both questions in the context of a calibrated dynamic general equilibrium model with Schumpeterian endogenous growth. Firstly, we demonstrate that, although the...
