Lorenzo Bretscher is Assistant Professor of Finance at the University of Lausanne. Before joining the faculty in Lausanne, Professor Bretscher was affiliated with the London Business School. In 2017, he was awarded the Nasdaq/European Finance Association Doctoral Tutorial Best Paper Award. Prior to his doctoral studies he worked as an analyst at Credit Suisse for two years. Professor Bretscher is currently studying the different effects of uncertainty on economic and financial outcomes. He shows that interest rate uncertainty predicts slowdowns in real activity at both the aggregate and the firm level. Such uncertainty reduces investment in spite of hedging opportunities, as risk management by means of swaps remains nonetheless risky. He further finds that uncertainty regarding government spending is priced into bond and stock portfolios, increases inflation, and generates both positive inflation risk premia and positive term premia. Such results are useful to investors in today's economy, marked as it is by high uncertainty and increases in the scope and effect of government and central bank interventions.
