The Real Exchange Rate, Innovation and Productivity

by Laura Alfaro, Alejandro Cuñat, Harald Fadinger, and Yanping Liu

Addressing debates on the effects of real exchange rate (RER) movements on the economy, this study examines manufacturing firm-level effects of medium-term fluctuations, in particular firm-level productivity across a wide range of countries. RER changes have different impacts depending on the export and import orientation of regions and the prevalence of credit constraints. Effects are non-linear and asymmetric, suggesting that the link between RER changes and macroeconomic performance might be much more nuanced than usually thought.

Banks’ Risk Exposures

by Juliane Begenau

Since the financial crisis, there has been renewed interest in documenting how much risk financial institutions are exposed to. This paper shares the important goal of that scholarship: to come up with a method that summarizes banks' positions in a meaningful way so that it will inform the theoretical modeling of these institutions and offer insights for policy decisions. Specifically, the paper measures banks' exposures to macroeconomic risk through their fixed income positions by representing those positions in terms of simple factor portfolios. Factor portfolios provide measures of exposure that are easy to interpret and compare across positions. The results help elucidate the evolution of bank risk taking over the last 20 years.

Accounting Data, Market Values, and the Cross Section of Expected Returns World

by Charles C.Y. Wang

Over the past 30 years, the central question in asset pricing is understanding what drives the variation in expected returns. Despite its importance, empirical research in this area has remained problematic because the key variable, expected returns, is not observable. This paper promotes an accounting-fundamentals-based approach to estimating expected returns. It contributes to the stream of empirical studies devoted to developing the estimation of, and understanding the behavior of, expected returns. It also provides a practical tool that can be used to analyze investment choices in international equity contexts. Closed for comment; 0 Comment(s) posted.

Implied Materiality and Material Disclosures of Credit Ratings

by Robert G. Eccles & Tim Youmans

Materiality—a concept at the core of financial, sustainability, and integrated reporting—means the "reportability" of economic, environmental, social, and governance (risk) issues. Using the lens of materiality, the authors of this paper examine principles underlying the methodologies and business models of credit reporting agencies (CRAs), finding that CRAs have potential governance shortcomings that need to be addressed by the boards of the CRAs themselves. The governance remedies recommended here aim to restore credit rating institutions to their historic role in the proper functioning of the global capital markets.
