The Effect of R&D and the Control–Ownership Wedge on Firm Value: Evidence from Korean Chaebol Firms

Abstract

Cases have been reported in which research and development (R&D) investment, the core activity for a firm’s sustainable growth, deteriorate rather than increase firm value. This study illuminates the cause of such cases in terms of the control–ownership wedge. How expensed and capitalized R&D affect firm value are examined separately for cases in which the wedge is high and low. In an analysis of Korean chaebol firms, when the wedge is high, significant negative relationships appear between expensed R&D and firm value, while no significant relationship appears between capitalized R&D and firm value. When the wedge is low, expensed R&D does not show any significant relationship with firm value, while capitalized R&D shows significant positive relationships with firm value. This confirms, first, that in cases of high wedge, suboptimal R&D decisions are made, in which the manager can discretionally determine investment targets or projects. Second, this indicates that even in cases of low wedge, the positive relationship between R&D and firm value does not appear in expensed R&D. This study suggests that investors and regulatory authorities should pay close attention to the initial stage of R&D in firms with high control–ownership wedges for sustainable economic growth.

The Effect of Marketing Investment on Firm Value and Systematic Risk

“…The author of [49] tested the relationship between ownership concentration measured by individually controlling shareholders' percentages and institutionally controlling shareholders and firm value; he found that both measures push down the firm value in Switzerland. Likewise, the expropriation impact of ownership concentration in the Korean market deepens the negative R&D-firm value relationship because of controlling shareholders hindering R&D investment decisions [50]. Meanwhile, a third line of research revealed no clear link between ownership concentration and firm performance; the authors of [51] reported that a high level of control by family or state shareholders in Arab Gulf listed companies did not show a significant impact of ownership on the market to book ratio.…”

Cashflow Management Practices and the Financial Performance of Five-Star Hotels in Nairobi County, Kenya

“…In the hotel industry, profitability measures including net profit, gross profit, and operating profit margins are frequently employed to evaluate financial stability and profitability. Gross profit margin reflects the hotel's ability to control direct expenses, operating profit margin measures profitability after accounting for operating expenses, and net profit margin assesses overall profitability considering all expenses (Kim & Kim, 2019). These financial performance measures, including net profit, gross profit, and operating profit margins, are commonly utilized to measure the monetary health and effectiveness of hotels in generating profits (Gibson & Dennett, 2018).…”
