International Stock Comovements with Endogenous Clusters
We examine international stock return comovements of country-industry portfolios. Our model allows comovements to be driven by a global and a cluster component, with the cluster membership endogenously determined. Results indicate that country-industry portfolios tend to cluster mainly within geographical areas that can include one or more countries. The cluster compositions substantially changed over time, with the emergence of clusters among European countries from the early 2000s. The cluster component was the main driver of country-industry portfolio returns for most of the sample, except ...

Fiscal Unions Redux
Before the advent of sophisticated international financial markets, a widely accepted belief was that within a monetary union, a union-wide authority orchestrating fiscal transfers between countries is necessary to provide adequate insurance against country-specific economic fluctuations. A natural question is then: Do sophisticated international financial markets obviate the need for such an active union-wide authority? We argue that they do. Specifically, we show that in a benchmark economy with no international financial markets, an activist union-wide authority is necessary to achieve ...

A new framework for assessing climate change risk in financial markets
While there is growing recognition that climate change poses a new risk for the economy, more research is needed to understand how climate change risk affects global financial markets. We establish a new framework for this research by merging the climate change risk categories of physical risk, transition risk, and liability risk with the risk categories commonly assessed in the financial markets: market risk, credit risk, liquidity risk, and operational risk. We then factor in market structure and market regulation as we seek to assess the overall impact of these variables on systemic risk. ...

International Stock Comovements with Endogenous Clusters
We use an endogenous cluster factor model to examine international stock return comovements of country-industry portfolios. Our model allows country-industry portfolio comovements to be driven by a global and a cluster component, with the cluster membership endogenously determined. Results indicate that country-industry portfolios tend to cluster mainly within geographical areas that can include one or more countries. The cluster component was the main driver of country-industry portfolio returns for most of the sample, except from mid-2000 to mid-2010s when the global component had a more ...
