Power Generation from Nuclear Fusion Not Expected in the Foreseeable Future: Applied Research Developing Dynamically

Research into nuclear fusion for military purposes has been regularly conducted since the 1940s. However, the idea of being able to use nuclear power for power generation within mere decades has not come to fruition. While some successes have been highlighted by the media, such as the experiments at the National Ignition Facility in California at the end of 2022, the main problems remain as challenging ...

Collateral Policy Surprises

Central bank collateral policy specifies which assets banks can pledge as collateral to obtain central bank funding and is an important determinant of liquidity in the banking system. We propose a high-frequency identification approach to study the systematic effects of central bank collateral policy on banks, financial markets, and asset prices. We identify collateral policy surprises using intraday ...
