英文摘要:
We propose two methods to obtain exact solutions for the Almgren-Chriss model about optimal execution of portfolio transactions. In the first method we rewrite the Almgren-Chriss equation and find two exact solutions. In the second method, employing a general reparametrized time, we show that the Almgren-Chriss equation can be reduced to some known equations which can be exactly solved in different cases.For this last case we obtain a quantity conserved. In addition, we show that in both methods the Almgren-Chriss equation is equivalent to a Riccati equation.

中文摘要:
我们提出了两种方法来获得Almgren-Chriss模型关于投资组合交易最优执行的精确解。在第一种方法中,我们重写Almgren-Chriss方程,并找到两个精确解。在第二种方法中,利用一般的重新参数化时间,我们证明了Almgren-Chriss方程可以简化为一些已知的方程,这些方程可以在不同情况下精确求解。对于最后一种情况,我们得到了一个守恒量。此外,我们还证明了在这两种方法中,Almgren-Chriss方程等价于Riccati方程。
