In this paper, we develop and examine a simple interactive agent‐based model, where the distribution of returns generated from the model takes into account two stylized facts about financial markets： fat tails and volatility clustering. Our results indicate that the risk tolerance of...

This study analyzes the emergence of secular stagnation as the consequence of a rise in the preference for liquidity. Such a rise is caused by a persistent set of pessimistic expectations. This study also investigates the effectiveness of a broad range of demand-management policies in dealing...

We use this shock to test predictions of speculative trading models with short-selling constraints. Symmetrically to Hong et al. (2006), where an increase in float decreases...

We investigate the implications of a scarcity of safe assets in a framework in which the safety of an asset is an equilibrium outcome. The intrinsic characteristics and supply of the assets determine their liquidity properties and degree of safeness. The equilibrium can be inefficient even if...
