Glacial erosion during the Last Glacial Maximum (LGM) has removed much evidence of earlier glaciations and interglacials in the European Alps. At Gröbminger Mitterberg (GM), beneath a blanket of LGM till, a distinctive sediment archive preserves deposits predating the LGM.

How Early Trauma Shapes CEO Risk Appetite for Public Debt Versus Bank Debt
ABSTRACT This study examines the impact of CEOs’ early disaster experiences on the choice of debt structure. We find that firms led by CEOs who have endured disasters are more inclined to shift from bank debt to public debt. This evidence remains robust across various alternative measures, empirical specifications, and identification tests aimed at ...

An Economic Analysis of Difficulty Adjustment Algorithms in Proof‐of‐Work Blockchain Systems
ABSTRACT We study the stability of cryptocurrency systems through difficulty adjustment. Bitcoin's difficulty adjustment algorithm (DAA) exhibits instability when the reward elasticity of the hash rate is high, implying that a sharp price reduction could disrupt the current Bitcoin system.
