We develop a financial market model focused on fund managers who continuously adjust their exposure to risk in response to the payoff gradient. The base model has a stable equilibrium with classic properties. However, bubbles and crashes occur in extended models incorporating an endogenous...

Do we know if a short selling ban or a Tobin Tax result in more stable asset prices? Or do they in fact make things worse? Just like medicine regulatory measures in financial markets aim at improving an already complex system, cause side effects and interplay with other measures. In this paper...

In this paper, we first document the growing importance of foreign-domiciled investment funds in countries' portfolio liabilities over time and then show empirical evidence that cross-border fund flows are coincident with asset price movements. To measure the external liabilities of countries to...

This has important implications for the conduct of monetary policy, as central bank policies may diverge across countries, potentially affecting key transmission channels of...

Can there be too much trading in financial markets? To address this question, we construct a dynamic general equilibrium model, where agents face idiosyncratic preference and technology shocks. A financial market allows agents to adjust their portfolio of liquid and illiquid assets in response...

Financial market crises with the threat of a subsequent debt-deflation depression have occurred with increasing regularity in the United States from 1980 through the present. Almost reflexively, when confronted with such circumstances, US institutions and the policymakers that run them have...

This paper provides a theoretical explanation of the accumulation process, which accounts for the developments in the financial markets over the recent past. Specifically, our approach is focused on the presence of correlations between physical and financial investment, and how the latter could...

We offer retrospective and prospective assessments of the Diebold-Yilmaz connectedness research program, combined with personal recollections of its development. Its centerpiece in many respects is Diebold and Yilmaz (2014), around which our discussion is organized.
