Conditions for the convexity of compound geometric tails and compound geometric convolution tails are established. The results are then applied to analyze the convexity of the ruin probability and the Laplace transform of the time to ruin in the classical compound Poisson risk model with and...

The power frequency high voltage divider is widely used to measure the power frequency high voltage and it is an important measuring instrument for high voltage test. Whether it is accurate or not directly affects the insulation monitoring level of power equipment closely related to the safety...

Preventing systemic risk from the perspective of bank risk accumulation has been widely researched and supported. This study focuses on the impact of economic volatility on bank risk accumulation and systemic risk. Using the proportion of non-core liabilities as the bank's risk accumulation...
