- Ho Chi Minh City Open University Journal of science- No. 1(1) 2011 87 The Effects R&D Expenditures On The Market Value In The Telecommunication Industry- Evidence From North America. By Nguyen Van Phuong1 The linkage between R&D spending and in manufacturing and non-manufacturing market value of firms has been continuously firms as well as the whole industrials. In debated from time to time. Many studies the internal role of R&D, scholars often have proved that there is a positive impact. study the influences of R&D investment on Meanwhile, other studies have proved that the firms’ innovations and patents. Some it depends on which sectors in the economy, authors following this trend are Levin at some sectors have a strongly positive effect el Griliches (1987) and Acs and Audretsch but the others have a weak effect. This (1998). In the external aspect of R&D, many paper estimates the relationship between authors focus on studying R&D operations R&D expenditures and market price in the as a very important strategy for firms to telecommunication sector. First, by using the be sustainable and achievable business COMPUSTAT annual industrials of North objectives under the pressure of the globally America in period 1950-2005, we find a competitive environment. In addition, the strong evidence of the positive relationship. external aspect has been rapidly expanded Second, we implement another test to and debated the phenomenon of outsourcing investigate some particular characteristics R&D expenditures. For instance, Henderson of the telecommunication sector during the and Cockburn (1994) provide evidence to process of liberalization telecommunication explain an essential fraction of the variance markets as well as the emerging internet in research productivity across firms; Quinn and developing Information Technology (2000) shows advantages of outsourcing era. Overall, our result is consistent with innovation such as resource limits, specialist some previous studies. Third, we expand talents, attracting talent and faster arrival the model and find that price per share is than in-house. positively associated with other variables In this paper, we estimate the including total assets per share and earning relationship between R&D expenditures per share. and market price in the telecommunication I. Introduction sector. The linkage between R&D spending The Research and Development (R&D) and market value of firms has been investment is playing a very important role continuously debated from time to time. in sustaining and achieving firms’ business Many studies have proved that there is a goals. The effects of R&D expenditures positive impact. However, other studies have been attracted more attention under have also proved that it depends on which many different aspects. There are many sectors in the economy, some sectors have different approaches to study the role of a strongly positive effect but the others R&D associated with firms’ innovations have a weak effect. For instance, Kothari and development. Overall, some scholars et al (2002) throughout empirical study focus on studying the effective internal as using financial data from 1972-1997 for a well as external role of R&D investment in large sample firm provides evidence that the whole economy. Meanwhile, the others the future benefits of R&D expenditures concentrate on analyzing the effects of are uncertainty than those of investments in R&D expenditure in a particular industry, capital expenditure. Ho et al (2005) shows 1 Post & Telecommunications Institute and Technology at Ho Chi Minh City

Finally, firms but not for non-manufacturing firms. Section 4 gives some concluding remarks. As our knowledge, most of previous II. Literature Review studies have concentrated on studying The role of internal R&D has been this linkage in the whole industrials or studied by many authors. One of pioneers manufacturing and non-manufacturing studying this trend is Griliches at el (1979 firms or some particular sectors such as the and 1987), the authors focus on studying the pharmaceutical and agricultural industry role of internal R&D in company innovation and so forth. The prior researches of this and show that the total number of innovations linkage in the telecommunication sector are is closely related to R&D expenditures. Acs limited resource. Therefore, the purpose and Audretsch (1988) develop this trend of this paper is to add to the literature and show that the total of innovations is on the effects of R&D expenditures on negatively associated with concentration market value in a particular industry, the and unionization, and closely associated telecommunication sector. with R&D investment, skilled labor and the By using the COMPUSTAT annual degree to which large enterprises comprise industrials of North America the in period the industry. Increasingly, many scholars 1950-2005, we select the telecommunication recognized that external R&D expenditures firms to test the relationship between market also contribute an essential role in firm value of firms in the telecommunication innovation rates and enhancing firm’s industry and R&D expenditures. As a result, competitive ability. Cohen and Levinthal we find a strong evidence of the positive (1990) study R&D contributing to a relationship. Second, we implement firm’s absorptive capacity and innovative activities including basic research, the another test by using usable observations diffusion and adoption of innovations and of the data for each firm and each year decisions to take part in cooperative R&D in period 1971-2005, the results have ventures as external factors. This trend reflected some particular characteristics of is followed by many other scholars. For the telecommunication sector during the instance, Henderson and Cockburn (1994) process of liberalization telecommunication study the significant role of heterogeneous markets as well as the emerging internet and organizational ‘competence’ in competition developing Information Technology (IT) in the context of pharmaceutical research and era. Overall, our result is consistent with the show that together two forms of competence previous studies. For instance, our result of (including component and architectural R&D per share achieves the peak in 1993, competence) provide evidence to explain an that is consistent with the result of Ogden et essential fraction of the variance in research al (2002, page 307). Third, we expand the productivity across firms. In general, in model by adding two independent variables the external aspect of R&D, many authors including total assets per share and earning consider analyzing the role of R&D per share to estimate the relationship investment as a very important strategy between price per share (PPS) with three for firms to be sustainable and achievable independent variables. As our expectation, business objectives under the pressure of all of the estimated coefficients are positive the globally competitive environment. and statistically significant. Now, we review prior studies of the The rest of this paper is organized role of R&D expenditures in improving as follows. In Section 2, we review prior firms’ financial status. Kothari et al

Guo future benefits of R&D expenditures are et al (2006) perform empirical study on a uncertainty than those of investments in sample of 2,696 US IPOs issued during the capital expenditure. Moreover, the effects period 1980-1995, they find that given the of increasing in R&D expenditures on the pervasiveness and constant growth of firms’ return and market value as well as the risky R&D activities in modern economies, R&D level of R&D operations have attracted expenditures play a major factor affecting more attention. For instance, Chan et al IPO’s performance and contribute the (1999) address the historical stock return of understanding of this important economic firms doing R&D on average matches the and capital market phenomenon. However, returns on firms with no R&D. On the other these effects of R&D investment could hand, they also find that R&D intensity is vary between non-manufacturing firms and positively relative to return volatility, after manufacturing firms. By empirical study of controlling for firm size, age and industry a 40 year period 1962-2001, Ho et al (2005) effects.

Here, of future earnings than capital expenditures we focus on analyzing the linkage between only in R&D-intensive industries, where R&D expenditures and market value of industry R&D intensity is measured as the firms in the telecommunication industry.

Overall, after 1996 the telecommunication sector fluctuated and the R&D investments in telecommunication sharply increased during the period 1985- firms have been diversified and spread 1994. One of many reasons able to interpret in many competitive firms, instead of this phenomenon is that this period rapidly concentration on monopolistic firms as emerged internet and the transmission before. This could be one of main causes control protocol (TCP)/internet protocol leading to the deterioration. In addition, the (IP) wide area network.

Moreover, to declining R&D expenditures per share most of telecommunication providers also in the late 1990s and following years.

Generally One of the main reasons for explaining the speaking, our results consistent with prior sharp reduction is due to the effective of an empirical research, for example, the R&Dps antitrust decree in 1994, as a result of the in the telecommunication sector achieved break-up AT&T from its local telephone the peak at $2.7 in 1993. Similarly, the monopolies and this change led to the way R&Dps for the S&P industrials also achieved on liberalization of telecommunication the peak at around $4.6 in 1993 and then it market. Furthermore, the effective tardily decline (see Figure 2). The fluctuation

The number of telecommunication firms has closely associated with the R&D firms in our sample is the same as before expenditures of the whole economy. This (287 firms) but the number of observations once more provides a strong evidence to is increased from 2261 to 2312. The data prove that the telecommunication sector process is the same as the above description has been playing a very important role in of the first model.
