기업의 경제적 성과측정 또는 경제적 척도로서 토빈의 Q는 가치에 대해 산출된 경제적 가치를 계산함으로써 이론적인 경제적 효율성의 개념에 가장 근접한 개념으로 평가되고 있다. 그러나 정확한 계산이 어려운 토빈의 Q대신 실제로는 회계적 수익률, 주가 수익률 및 장부가격 대비 시장가치 비율(MB)등이 편의상 많이 사용되고 있다. 본 논문에서는 이러한 성과 측정 변수들간의 상관관계를 실증적으로 검증함으로써 이들 세 유형의 변수들이 토빈 Q의 대용적(代用的) 변수(變數)로서 신뢰성과 유용성이 있는지를 판정하고자 하였다. 연구 결과는 MB를 제외하고는 이들 변수들이나 또는 이들의 조합이 토빈 Q비율을 충분히 설명하기에는 너무 미흡하여 토빈 Q의 대용변수로서 경제적 효율성의 판단기준으로 사용될 경우에 그 신뢰성에 의문이 제기될 여지가 있음을 시사하고 있다. 특히, 회계적 수익률은 토빈 Q비율에 대한 설명력이 현저히 낮을 뿐 아니라, 이러한 결과는 수익률의 이동평균을 사용하거나, 연구개발비나 계열기업집단의 소속여부에 의해 잠재적인 무형자산의 영향을 반영할 수 있도록 수익률을 보완하여 사용하더라도 그 설명력이 크게 개선되지 않는 것으로 나타나고 있다.

본 연구는 Tobin-Q 비율(이하 토빈 Q, 또는 Q)을 이용하여 합병제의기업과 피합병대상기업을 합병전 경영성과의 우열에 따라 분류하고, 분류 집단별 초과수익률을 측정 검증함으로써 합병전 후의 합병관련기업의 합병효과를 분석하였다. 실증분석 결과를 보면 합병제의기업과 피합병기업 모두 합병 공시 후 양의 초과수익률을 얻는 것으로 나타났으며, 합병제의기업은 토빈 Q가 낮을수록 합병성과가 크게 나타났고, 피합병대상기업은 토빈 Q가 높을수록 합병성과가 크게 나타났다. 또한 합병제의기업과 피합병대상기업의 토빈 Q를 동시에 고려한 경우에는 합병제의기업의 Q가 높고 피합병대상기업의 Q가 낮으면, 합병성과가 작았고, 합병제의기업의 Q가 낮고 피합병대상기업의 Q가 높으면 합병성과가 높게 나타난다는 경향을 관찰할 수 있었다. 이러한 연구결과는 경영성과가 좋은 합병제의기업이 대체적으로 이득을 보지만, 경영이 부실한 피합병대상기업을 인수할 때 더 많은 이득을 본다는 Lang, Stulz, Walkling(1989)의 연구결과는 상반되는 것이다. 또한 경영성과가 나쁜 기업을 합병함으로써 보다 많은 합병가치 창조가 가능하다는 Servaes(1991)의 연구결과와도 상반되는 것이다. 이러한 상반된 결과는 우리나라 현실에서 합병이 대개는 계열그룹내, 또는 지배회사와 피지배회사간의 합병이 주류를 이루고, 세법상 합병기업의 손실은 승계되지만 피합병기업의 손실은 승계되지 않으므로 형식상 합병제의기업과 피합병대상기입이 뒤바뀌는 경향이 많다는 점에서 그 원인을 추정할 수 있다.

In this research, it is empirically tested whether firm value after the adoption of IFRS is increased in Korea and China using Tobin's Q model. In Korea, IFRS was mandatorily adopted in 2011 for all companies. China mandated IFRS conversion for public traded companies starting 2007. The revisions bring Chinese standards closer to the IFRS benchmark of internationally recognized quality, but the new standards will not be word-for-word translations of IFRS, though they founded on similar principle. We expect the different adoption process between Korea and China can make different impact of IFRS on firm value. The results are summarized as follows. First, Tobin's Q seems to be increased after the adoption of IFRS, and the firm value is significantly different between before and after IFRS adoption in Korea. Second, Tobin's Q seems to be increased after the adoption of IFRS, but the analysis by t-test is not significantly higher for post IFRS. These results could be a good finding in that the impact of IFRS adoption on firm value is different by adoption process.

It is easy for first movers of platform business model to monopolize the market due to the platform's own characteristics such as network effect and flywheel strategy. Accordingly, the regulations on platform operators are constantly being discussed in the recent monopoly regulation arguments, but the concrete regulations have not been settled worldwide. This is because there is no clear consensus on the valuation method which can objectively identify dominant platform firms from the others. This study suggested a platform valuation method based on the Tobin's Q theory, by measuring the moderating effect of the existence of specific scale of platform on the relationship between replacement cost and market valuation. Our method can not only be a standard for settling monopoly regulation by converging the regulation targets, but also contribute to active investment on the new platform firms by evaluating their potential growths quantitatively.

Estimating investment profits of real estate is critical to understand real estate markets and create relevant policy as real estate market and capital market combines closely. Thus, this study applied the concept of Tobin's Q to estimate investment profits for apartments as well as row-houses and multi-family homes in Seoul from 2010 to 2018. Investment profits were estimated by two approaches: subtracting the replacement cost from the transaction price and calculating ratio of the transaction price to the replacement cost, respectively. The spatio-temporal changes in investment profits were apparent in apartments compared with row-houses and multi-family homes. As a result of analyzing the spatial econometrics models, the investment profit was higher in the area with high density and new developments regardless of the housing types. The framework and key findings would be the effective reference to understand residential investment behavior, create relevant housing policy, introduce value capture of windfall, measure regional competitiveness, and estimate housing bubble.

We posit that employee ownership through defined contribution (DC) plans results in managerial entrenchment, and then examine the effect of the enactment of the Pension Protection Act of 2006 on the relation between the employee ownership and firm performance. By conducting Ordinary Least Square regression with the data from Form 5500 over the period of 1999-2014, we find that firms with large employee ownership increase their firm value measured by Tobin's Q after the adoption of the Act. These findings suggest that the adoption of the Act has been effective to mitigate the negative effect of managerial entrenchment by decreasing the employee ownership and reinforcing the fiduciary duty of plan trustees. Given the fact that we test the effects of the diversification rule on employee ownership using firm performance, further research could aim to examine the effects of the rule on employee ownership using stock return or market reaction.

The environmental, social, and governance (ESG) score is gaining recognition as important nonfinancial investment criteria. With climate change emerging as a global issue, energy companies must pay attention to the ESG impact on corporate performance. In this study, the ESG impact on the performance of energy companies was analyzed based on 23 companies selected from the S&P 500. The panel corrected standard error methodology was used. The Refinitiv ESG score was the independent variable, and financial performance metrics, such as Tobin's Q, return on assets, and return on equity, were the dependent variables. It was found that the ESG score is positively associated with long-term corporate value but not with short-term profitability in the electricity utility industry. Among the subcategories of ESG, the environmental and social scores also showed positive correlations with long-term corporate value. A direct incentive policy is recommended that can offset expenses for ESG activities to reduce carbon emission in the energy sector.

This study examines the ratio of R&D expenses in intangible assets for pharmaceutical companies, and determines whether these expenses affect the firm value among companies listed on the KOSDAQ. The research subjects included annual R&D expenses of 39 pharmaceutical companies listed on the KOSDAQ between 2011 and 2017. The survey was achieved via "Panel Data Model" with "Tobin Q" as an independent variable, and the ratio of R&D expenses in intangible as a dependent variable. Results of the study conclude that the ratio of R&D expenses in intangible assets of KOSDAQ pharmaceutical companies negatively influence the Tobin Q (Enterprise Value). A large proportion of intangible assets indicates increased R & D investment, and the operating profit is likely to be low due to the high debt ratio, thereby negatively impacting the enterprise value. This study further investigates whether the existing researches are based on researches that identify the total value of R & D expenditure. Results determine a significant relationship between enterprise value and R & D expenditure.

The purpose of this study is to identify the CSR activities and to investigate the relationship between CSR activities and business performance. Specifically, we analyzed the companies that were included in the SRI index as CSR activity companies, and analyzed how they affect the business performance of the companies according to SRI index incorporation disclosure. As a result of the analysis, the SRI index incorporation announcement has a significant positive effect on the corporate value(Tobin's Q) but it has not significant effect on the financial performance(ROA). This suggests that CSR activities are offered to companies' managers and stakeholders as a basis for investment rather than expense. In the future research, it will be more meaningful if the study on the intention to participate in CSR activities is conducted based on this study and previous studies.

This paper examines the effect of corporate social responsosibility(CSR) on the firm value. Based on the argument that CSR would play the role of mitigating conflicts between firms and society, I hypothesized that CSR would enhance the firm value. This study used regression analysis with a data set of 733 from 2009 to 2012 using KEJI(Korean Economic Justice Institute) Index. An Index published by KEJI was used as the measure of CSR performance. The results of this study are summarized as follows: First, there is a significant positive relation between CSR and firm value. Second, in the seven-rating items consist of the KEJI Index, most items have the positive relationship with the firm value. These results suggest that firm with higher CSR activities exhibit better financial performance as measured by Tobin's Q.
