This paper analyzes how consumer uncertainty affects optimal fiscal policy in the Lucas and Stokey (1983) framework. The consumers, lacking confidence in their knowledge of the stochastic environment, endogenously tilt their subjective probability model away from an approximating probability...

This paper develops a theory of endogenous growth cycles focusing on the interaction between consumers' desire to satisfy an indefinite range of wants and firms' incentive to utilize knowledge from past production experiences. We show that firms endogenously form a number of distinguishable...

We extend the standard textbook search and matching model by introducing deep habits in consumption. This assumption generates amplification in the response of labour market variables to technology shocks by producing endogenous countercyclical mark-ups. The cyclical fluctuations of vacancies...

This paper demonstrates that the analysis of fiscal sustainability of social security must include the education funding dimension of public policy, which affects the productivity of future workers. This fact is true under both social security regimes: pay-as-you-go (PAYG) and fully funded (FF)....

We provide small noise expansions for the value function and decision rule for the recursive risk-sensitive preferences specified by Hansen and Sargent (1995), Hansen et al. (1999), and Tallarini (2000). We use the expansions (1) to provide a fast method for approximating solutions of dynamic...

We report results from an experiment in which humans repeatedly play one of two games against a computer program that follows either a reinforcement or an experience weighted attraction learning algorithm. Our experiment shows these learning algorithms detect exploitable opportunities more...

We study optimal government spending in a business cycle model with labor income taxes and unemployment due to hiring costs. Labor market frictions raise the optimal steady state ratio of government spending to private consumption. The labor tax rate is higher since profits are taxed that arise...

This paper embeds an oligopolistic industry structure in a real options framework in which synergy gains of horizontal mergers arise endogenously and vary stochastically over time. We find that (i) mergers are more likely in more concentrated industries; (ii) mergers are more likely in...

We quantify the short-run and long-run price effect of posting a limit order in an order book market by proposing a high-frequency cointegrated VAR model for quotes and order book depth. Estimating impulse response functions based on data from 30 stocks traded at Euronext Amsterdam we show that...

This paper extends the analysis of the seminal work of Brock and Hommes (1997, 1998) on heterogeneous beliefs and rational routes to randomness in discrete-time models to a continuous-time model of asset pricing. The resulting model characterised mathematically by a system of stochastic delay...
