AI Article Synopsis

  • - The paper analyzes how the COVID-19 pandemic has affected financial markets around the world, focusing on major stock indexes in 23 countries across North and South America, Europe, and Asia.
  • - It utilizes robust estimation techniques to examine the relationship between pandemic-related statistics (like infections and deaths) and stock returns, highlighting the importance of these factors in financial analysis.
  • - The study also investigates the characteristics of COVID-19 data over time, including persistence and tail risks, which supports the need for advanced statistical methods in financial econometrics.

Article Abstract

The paper focuses on econometrically justified robust analysis of the effects of the COVID-19 pandemic on financial markets in different countries across the World. It provides the results of robust estimation and inference on predictive regressions for returns on major stock indexes in 23 countries in North and South America, Europe, and Asia incorporating the time series of reported infections and deaths from COVID-19. We also present a detailed study of persistence, heavy-tailedness and tail risk properties of the time series of the COVID-19 infections and death rates that motivate the necessity in applications of robust inference methods in the analysis. Econometrically justified analysis is based on heteroskedasticity and autocorrelation consistent (HAC) inference methods, recently developed robust t-statistic inference approaches and robust tail index estimation.

A Novel Method for Hemorrhage Control During Laparoscopic Distal Pancreatectomy with Splenic Vessel Preservation: Triple Occlusion.

Ann Surg Oncol

Division of Pancreatic Surgery, Department of General Surgery, West China Hospital, Sichuan University, Chengdu, Sichuan, China.

Introduction: Laparoscopic distal pancreatectomy (LDP) has the advantages of reduced blood loss, shorter hospital stays, and a better postoperative quality of life compared with open distal pancreatectomy (ODP). Meanwhile, spleen-preserving laparoscopic distal pancreatectomy is the preferred technique for low-grade malignant and benign tumors located in pancreatic body and tail, since it preserves the immune function of the spleen. The splenic-vessel-preserving (SVP) Kimura technique and splenic vessel resection Warshaw technique are the two primary procedures.

How do physical environment risks affect financial market systemic risk? We use remoting data to measure physical environment risks and select 26 banks across 12 EU countries. We extend the CoVaR framework with the quantile-mLSTM algorithm, obtaining time-varying CoVaRs. We then use time-varying partial derivatives to calculate the banks' tail risk spillover effects.

Background: Pancreatic enucleation is indicated for selected patients and tumours with very low oncological risk to preserve a maximum of healthy pancreatic parenchyma. Minimally invasive pancreatic enucleation (MIPE) is increasingly performed. This study aims to assess the impact of tumor location and center experience on textbook outcomes (TBO) in patients undergoing MIPE.

The current study aims to elicit information regarding the tail risk transmission mechanism between crude oil (CO) and selected clean energy (CE) stock indices across time and during certain economic events. A Time-Varying Parameter Vector Auto-Regressive model (TVP-VAR) paired with the conditional autoregressive value-at-risk (CAViaR) approach was used to investigate data from January 1, 2015 to December 29, 2022. Overall, we show that an increased vulnerability to tail risk and deficits might be linked to dynamic spillover over examined markets.
