Fields: Macroeconomics, macro-labor, financial frictions

Short bio

Karl Walentin has been working at the Research Division of Sveriges Riksbank since 2005 and received his Ph.D. from New York University the same year. He has visited the Federal Reserve Board (2008) and the Federal Reserve Bank of San Francisco (2012) for extended periods.

 

Karl's main research area is macroeconomics with a focus on business cycles. Karl has done research on the importance of financial factors for the business cycle. For example, he has documented the importance of residential mortgage spreads for cyclical variation in macroeconomic variables. As part of that project he also quantified the macroeconomic effects of mortgage-related large scale asset purchases by the Federal Reserve. Karl has also built and estimated DSGE models of various kinds, both for research and policy purposes. His most recent work concerns issues within macro labor. Together with Andreas Westermark he is quantifying how volatility of unemployment contributes to the cost of business cycles by reducing the level of GDP. An important amplifying mechanism in this context is learning on-the-job – the fact that people accumulate human capital when they work.
