We consider the popular problem of sparse empirical risk minimization with linear predictors and a large number of both features and observations. With a convex-concave saddle point objective reformulation, we propose a Doubly Greedy PrimalDual Coordinate Descent algorithm that is able to exploit sparsity in both primal and dual variables. It enjoys a low cost per iteration and our theoretical ...

The objective of this study is to investigate the factors affecting firm competitiveness in an emerging market—Turkey. In the paper, competitiveness is proxied by a firm’s financial performance. The empirical analysis is based on firms listed on Borsa Istanbul and covers the period between 2005 and 2014. Results from a firm-level panel data model indicate that return on assets is positively rel...

We prove that Brownian market models with random diffusion coefficients provide an exact measure of the leverage effect [J-P. Bouchaud et al., Phys. Rev. Lett. 87, 228701 (2001)]. This empirical fact asserts that past returns are anticorrelated with future diffusion coefficient. Several models with random diffusion have been suggested but without a quantitative study of the leverage effect. Our...

Conflicts of interest between insiders (e.g, controlling shareholders) and outsiders (e.g., minority shareholders) are central to the analysis of modern corporation. In an integrated continuous-time contingent claims framework with imperfect corporate governance, we examine a controlling shareholder’s optimal choice of capital structure, ownership concentration, private benefit diversion, consu...

This paper analyzes the relationship between capital structure and earning management. For analysing we used 119 non-financial companies that listed in Tehran Stock Exchange from 2000 to 2008. The researchers will focus on comparing the Jones Model and the Modified Jones Model, which are the two most frequently used model in empirical analysis nowadays. Earnings management is a kind of manageme...

This paper analyzes capital structure between the internationalized and domestic electronic industries in Taiwan from 1999 to 2008 as the reference for financing strategies and decision. The evidence shows that the leverage and the payout cash dividend ratio in the internationalized electronic firms are lower than those in domestic electronic firms. Due to the uniqueness and the high profit abi...
