The literature on working capital management (WCM) provides mixed evidence on the effect of working capital on firm profitability and performance. We use firms from developed and emerging economies to explore how working capital and its components relate to firms’ performance while controlling for firm-specific and macroeconomic factors. The findings show that the cash conversion cycle (CCC) is inversely related to firm performance in developed and emerging economies—however, there are differences in the CCC’s components. While firms in developed economies exhibit higher firm performance with longer days’ inventory on hand, firms in emerging economies have lower firm performance with longer days’ inventory on hand, extended collection periods, and longer payable periods. Company-specific factors, such as firm size, growth, profitability, and leverage, influence the efficiency of WCM. We also find that country-specific variables such as gross domestic product (GDP), interest rate, and inflation have varying impacts on a firm’s WCM.

We examine why Korean firms issue hybrid securities, including convertible bonds and bonds with warrants. In particular, we investigate whether there exist any differences between companies issuing convertible bonds and those issuing bonds with warrants. Our findings show that younger firms with more growth opportunities, larger size, high leverage, low profitability, low credit rating, and low ownership concentrations are likely to issue more hybrid securities rather than straight debt or equity. Also, we find that firms with more growth opportunities, larger size, low profitability, and higher ownership concentrations prefer to issue convertible bonds rather than bonds with warrants. Although we find that the announcement effects of both convertible bonds and bonds with warrants are significantly positive, the cumulative abnormal returns are higher for convertible bonds than for bonds with warrants.

Purpose
The impact of founder CEOs on firm value continues to be debated in the finance literature. While earlier studies suggest that founding family ownership and founding CEO structure create less value than public ownership, later studies provide contradicting evidence. This study examines how founder CEOs affect firm value in the business group context while controlling for firm-specific variables and various CEO characteristics.

Design/methodology/approach
The authors use a sample of publicly listed Indian firms from 2010 to 2015 with 997 firm-year data observations. While 306 of these are in business groups, the remaining 691 are in a nonbusiness group. The authors also divide the sample into various sector subgroups, including materials (170), industrials (198), consumer (422) and others (198). They use two different models, including the fixed effect model (FEM) and pooled generalized method of moments (GMM) model to run regressions.
