        What Is the Role of the Risk Aversion Parameter in the Almgren-Chriss Execution Model?
        
         
        
        
          
        
        
      
        
     
        
        The risk aversion parameter calibrates the optimal trade-off between market impact cost and price uncertainty in execution algorithms.
        
        What Is the Trade-Off between VWAP Tracking and Minimizing Implementation Shortfall?
        
         
        
        
          
        
        
      
        
     
        
        The trade-off is choosing between VWAP's passive conformity to market flow versus IS's active optimization of total cost from decision time.
