Due to the fact that assets are recorded at their historical value and they may include unrealized gains (losses), managers may manipulate earnings through the sale of these assets and provide financial information which is not accurate and reliable. The aim of this study is to investigate the relationship between income from asset sales, earnings change and leverage of companies listed on Tehr...

Large heterogeneity has prevented current capital structure research from explaining variations in firms’ capital structures to a satisfactory degree. We find that firms generally fall into two categories based on their capital structure policies. One category consists of larger firms that tend to pay dividends, and includes almost all zero-leverage firms in the sample. These firms tend to resp...

The sampling strategies in many randomized matrix algorithms are, either explicitly or implicitly, controlled by statistical quantities called leverage scores. We present four bounds for the sensitivity of leverage scores as well as an upper bound for the principal angles between two matrices. These bounds are expressed by considering two real m×n matrices of full column rank, A and B. Our boun...

Optimal transport as a loss for machine learning optimization problems has recently gained a lot of attention. Building upon recent advances in computational optimal transport, we develop an optimal transport non-negative matrix factorization (NMF) algorithm for supervised speech blind source separation (BSS). Optimal transport allows us to design and leverage a cost between short-time Fourier ...
