Institutional investment horizon and corporate technological diversification

Although investigating the factors influencing technological diversification is essential to understanding research and development (R&D) strategies, studies from the perspective of corporate ownership structure are limited. This study examines the effect of heterogeneous institutional investors on technological diversification strategies.

The sample consists of 33,124 firm-year observations of USA manufacturing firms from 1981 to 2008. Data were extracted from US Patent Data, Thomson Reuters' 13f and the Compustat database. A panel regression analysis was used to test the hypothesis. Moreover, the two-stage least squares (2SLS) approach using instrumental variables (IVs) and generalized method of moments (GMM) were also applied to address the endogeneity issue.

The empirical findings indicate that short-term (long-term) institutional investors positively (negatively) affect technological diversification. That is, short-term institutional ownership hampers R&D diversification, suggesting that firms are forced to make myopic investments to meet short-term goals instead of diversifying corporate R&D projects. Meanwhile, long-term institutional ownership enhances technological diversification to achieve long-term value.

By differentiating between institutional investment horizons, the authors produce empirical evidence that institutional investors with short-term and long-term perspectives have different views on technological diversification. This study is based on data between 1981 and 2008, due primarily to patent data availability and data on institutional investors. However, this limitation does not diminish the importance of the empirical findings, as the study's focus is on discovering antecedent evidence of corporate technological diversification rather than addressing recent trends in firm decisions.

In finding that long-term institutional investors are likely to encourage technological diversification at firms, the paper carries an important practical implication that can help inform decision-making by policymakers and investors.

This research contributes to a more comprehensive understanding of institutional investors' role in technological diversification strategies. Additionally, by challenging the assumption that all institutional owners share the same perspective, this study is the first to confirm the existence of heterogeneous effects of institutional investors on technological diversification strategies.
