The purpose of this paper is to evaluate the importance of financial liquidity and solvency on US commercial and domestic banks’ cost efficiency while accounting for internal and external factors.,The Stochastic Frontier Analysis and Data Envelopment Analysis estimators are used to estimate the cost efficiency of 11,044 US commercial and domestic banks from 2005 to 2017. Using Tobit regression model, the importance of financial liquidity and solvency on cost efficiency is examined.,The results provide evidence that the financial liquidity and solvency negatively impact the cost efficiency of US commercial and domestic banks. Overall, US commercial and domestic banks were inefficient during the financial crisis in comparison to the tranquil period. The importance of financial solvency on the cost efficiency was not statistically significant, while the financial liquidity negatively collapsed because of contagion. Finally, the results provide evidence that the amount of total assets matters in the improvement of the cost efficiency.,This paper estimates and identifies the 2007-2009 financial crisis with liquidity, solvency or both financial factors.

金融流动性和偿付能力对成本效率的影响：美国银行系统的证据

本文的目的是评估金融流动性和偿付能力对美国商业和国内银行成本效率的重要性，同时考虑内部和外部因素。随机前沿分析和数据包络分析估计器用于估计美国银行的成本效率。 2005年至2017年间，共有11,044家美国商业和国内银行。使用Tobit回归模型，研究了金融流动性和偿付能力对成本效率的重要性。结果提供了证据，表明金融流动性和偿付能力对美国商业和国内银行的成本效率产生了负面影响银行。总体而言，与平静时期相比，美国商业和国内银行在金融危机期间效率低下。财务偿付能力对成本效率的重要性在统计上并不显着，而金融流动性则由于传染性而急剧下降。最后，结果提供了证据，表明总资产的数量与成本效率的提高息息相关。本文估计并确定了具有流动性，偿付能力或同时包括两个财务因素的2007-2009年金融危机。
