ABSTRACT I examine the effects of information asymmetry–driven mispricing on security issuance. Using predisclosure changes in purchase obligations as a proxy for information asymmetry–driven mispricing, I find that managers avoid (prefer) issuing securities when they perceive their firms to be undervalued (overvalued). The effects of information asymmetry–driven mispricing are stronger on equity issuance than debt issuance. Consequently, undervaluation (overvaluation) causes an increase (decrea

We investigate the effects of incentive-alignment mechanisms on voluntary disclosure of carbon emissions in Korea, a latecomer in incorporating environmental practices into business operations. We consider in particular the effects of corporate governance and compensation mechanisms. We find that international aspects of governance mechanisms, measured by foreign ownership and foreign subsidiaries, are positively associated with the likelihood that a firm discloses carbon emissions voluntarily a

Lazertinib is an oral, irreversible, third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) thatforms an irreversible covalent bond to the Cys797 residue in the ATP-binding site of the EGFR kinase domain and exhibits a highselectivity for sensitizing and T790M EGFR mutations. In January 2021, it was first approved for the treatment of advanced ormetastatic non-small cell lung cancer (NSCLC) patients with EGFR T790M who had previously received EGFR TKI therapy ba

Abstract We examine the effects of environmental regulations on the profitability and value of Korean listed firms, exploiting the first phase of the Korean Emissions Trading System (ETS) as an exogenous shock. While previous studies have mainly focused on environmental regulations in developed countries, often yielding inconclusive results, emerging markets like South Korea remain less explored. Using data on Korean listed firms from 2011 to 2017, we explore the effects of the 2015 Korean ETS o

This study identified the characteristics of fashion rental service users as well as analyzed their purchase decision-making processes. A qualitative investigation was conducted through in-depth interviews with 13 women in their 20s–30s who have experienced renting fashion items due to a high interest in fashion. The results of the study are summarized as follows. The need recognition stage analyzed ventilation by mass media, SNS impact, curiosity, saving shopping time and money, awareness of si

We compartmentalize research and development (R&D) into R (research) and D (development), and investigate their association with corporate financing decisions. We find that only R is positively associated with cash holdings and sensitive to cash flows. Consistent with the product market risk that D bears, only D is associated with higher cash holdings when product market competition is severe. Lastly, only R is negatively associated with financial leverage. These results are consistent with the

I examine the effects of fair value reporting of derivatives, in accordance with SFAS No. 133, on corporate risk management policies and firm value. Prior studies predict that effective risk management through derivatives use reduces demand for liquidity and increases debt capacity. Using difference-in-differences analyses, I find that firms that are affected by SFAS No. 133 reduced cash holdings. In addition, treatment firms increased leverage but did not experience increased cost of debt or lo
