A comparative analysis of layoff announcements and stock price reactions in the United States and Japan

Downsizing and layoffs are an important mechanism for U.S. firms to cope with their strategic and economic environment. In contrast, the Japanese tradition of lifetime employment limits the ability of firms to employ layoffs as a strategic measure, relegating its use to conditions of financial distress. This paper provides the first comparison of layoffs in Japan and the United States and examines stock price reactions to layoff announcements in each country from 1990 to 1994. Agency theory and Aoki's cooperative game theory are employed to discuss differences in the governance structures of U.S. and Japanese firms and their implication for stock price reactions. Results show that layoff announcements trigger negative returns for both U.S. and Japanese firms. Specifically, layoff announcements of U.S. firms are associated with a negative 1.78 percent abnormal return, while layoff announcements for Japanese firms are associated with a negative 0.56 percent abnormal return. To better understand the impact of layoffs, this study examines the relationships between stock price reactions and various layoff characteristics (such as whether the layoff is proactive or reactive or whether the layoff is the first in the industry). Implications of the findings are discussed. © 1997 John Wiley & Sons, Ltd.     

Private and social incentives to form R & D joint ventures

R & D patent pools induce individual firms to reduce investment in R & D, but are socially beneficial because they ensure greater competition in the post-innovation market. It is not usually optimal for all firms to combine in a single cooperative R & D venture. If R & D combinations are formed voluntarily by firms that seek to maximize their expected value, they will not, in general, adopt the socially optimal structure of R & D joint ventures.     

A Note on Endogenous Spillovers in a Non-Tournament R & D Duopoly

The paper analyzes a simple non-tournament model of R & D where firms are engaged in cost-reducing innovation. It is shown that when spillovers of information are treated as endogenous firms never disclose any of their information when choosing their R & D non-cooperatively. Under cooperative R & D, firms will always choose to fully share their information, i.e., a research joint venture will operate with a maximal spillover value.     

Acquisition announcements and stock market valuations of acquiring firms' rivals: A test of the growth probability hypothesis in China

To examine the impact of acquisition announcements on the stock market returns of rivals of the acquiring firms, we propose a growth probability hypothesis: when an acquisition is announced, it signals the potential for future growth in the acquirer's industry to the market, resulting in positive stock market reactions to rivals of the acquiring firms. We test the growth probability hypothesis with a longitudinal sample of Chinese domestic and cross‐border acquisitions during 1993–2008. The results provide robust support for this hypothesis as a means to explain market reactions to rivals of acquiring firms. We also empirically test and negate alternative theoretical explanations advanced in prior literature to explain positive market reactions to rivals of the target firms.

Firm Density and Industry R & D Intensity: Theory and Evidence

By deriving a formal model of industry R & D that identifies factors influencing industry R & D intensity, this paper first suggests firm density, defined as the inverse of average firm sales or simply the number of firms divided by industry sales, as a measure of market structure that is appropriate in explaining industry R & D intensity. The model shows that the cost structure of R & D, consumer preference over quality and price, the appropriability of R & D, firm density, and the average level of firm R & D intensity jointly determine industry R & D intensity. In particular, firm density has a positive relationship with industry R & D intensity, implying that firms in higher firm-density industries feel fiercer competitive pressure and thus engage more intensively in R & D. An empirical analysis of panel data on industry R & D activities of Korean manufacturing industries during the period 1991–1996 provides supportive evidence for the predictions of the model including the positive relationship between firm density and industry R & D intensity. The theoretical model and the empirical results are also consistent with the recent survey of U.S. corporate R & D activities by the U.S. Department of Commerce and the National Science Foundation (1999).     

Getting the most out of cross-functional cooperation: Internal structural change as a trigger for customer information use

Using customer information in the decision making of R&D and production is vital for industrial firms to survive and prosper in an increasingly competitive marketplace. Previous studies show that cross-functional cooperation may have both negative and positive effects on information use. The authors hypothesize that internal structural change positively moderates the relationship between cross-functional cooperation and information use. However, structural change also decreases the quality of cross-functional cooperation. Cross-functional knowledge increases both cross-functional cooperation and customer information use. These hypotheses are tested and supported using a data set consisting of 221 manufacturing and R&D managers in large industrial firms. The findings imply that although internal structural change increases the benefits of cooperative, cross-functional relationships in terms of customer information use, managers in volatile organizations should continue to strengthen cooperative relationships by maintaining and improving sales and marketing contact people's knowledge of manufacturing and R&D.     

Does it Pay to be Flexible?

This paper addresses the determinants of price-cost margins inU.S. 4-digit industries. Margins are larger in capital intensive andconcentrated industries with high growth rates and R & D andadvertising to sales ratios. They also fluctuate significantly overthe business cycle. We go beyond the existing literature byconsidering an issue which is a dominant topic in the businessliterature, the flexibility of firms to adjust to exogenous shocks.In particular, we find a significant positive relationship betweenthe flexibility of labour demand and price cost marginssuggesting that it pays to be flexible.     

Mass Layoffs and CEO Turnover

We investigate the relationship between layoff announcements and CEO turnover over a 31-year period. We find that layoffs significantly increase CEO turnover in the following year, and, in some time periods, CEO changes are strongly positively associated with layoff announcements two years earlier. We proceed to show how this relationship has changed over time, and offer several possible explanations. Finally, we find strong evidence that layoffs that are associated with negative stock price reactions are much more likely to lead to CEO turnover than those associated with positive stock price reactions, especially in the earlier years in our sample.     

Product Innovation,Process Innovation,and Size

We test the hypothesis that large firms devote a higher proportion of their research and development (R & D) expenditure on process innovation thansmaller firms. According to the estimates, process- and product R & D expenditure rise less than in proportion to size. The size effect is somewhat stronger for process R & D but the difference to product R & D is in no way dramatic. This difference with regard to size elasticity of process- and product R & D is somewhat more pronounced when accounting for possible interrelationships between expenditure on process- and product R & D but remains statistically non-significant.     

Effects of R & D Spillovers on the Profitability of Firms

This cross-section study of a sample of 278 firms from the COMPUSTAT II database explores the relationship between a firm's profitability and other variables, notably its own R & D capital, knowledge and market spillovers and appropriability. The proxy for knowledge spillovers is based on technological distance. Market spillovers are based on a patent input-output matrix. Both spillover proxies combine information on R & D expenditures and patent counts.The results do not reject the hypothesis that R & D has a direct, positive effect on profitability, especially in industries with effective patent protection. Information spillovers affect profits negatively, market spillovers positively.     

Corporate Headquarters Relocation: Evidence from the Capital Markets

This paper assesses the stock market reaction to announcements of corporate headquarters relocations and examines financial and geographical factors related to wealth effects and factors that influence the decision to relocate corporate headquarters. The results indicate that announcements of relocations are associated with significant positive stock price effects. On average, the stock price of relocating firms increases by 1.29% during the two-day period around the announcement. Abnormal returns are positively related to the availability of labor and negatively related to the cost of living in the new location and the change in employment levels. A logit analysis indicates that the probability of a firm relocating is partially determined by the firm size and the rental expenses/sales ratio. The results also indicate that firm size, the employment/asset ratio levels, and listing in the NYSE/AMEX affect the decision to relocate to a Fortune-ranked city. Finally, firms relocating to Fortune -ranked cities are characterized by a high level of insider ownership relative to firms moving to non-ranked cities.     

Insider trading as a vehicle to appropriate rent from R&D

While most insider trading is routine and legal, investors still treat it as new information about the firm's prospects—they assume that trades reflect managers' attempts to profit from their private information. This article explores insider trading as a mechanism to appropriate rent from R&D advances. We analyze stock price reactions to over 134,000 insider‐trading events and find that insider purchases generate larger positive stock price reactions for R&D‐intensive firms. Investors seem to assume that managers use insider trading to appropriate rent from R&D breakthroughs. We discuss how shareholders may prefer this rent appropriation mechanism over other forms of compensation that directly reduce the firm's income. Copyright © 2002 John Wiley & Sons, Ltd.     

Alliance capability,stock market response,and long‐term alliance success: the role of the alliance function

This paper addresses two key questions: (1) what factors influence firms' ability to build alliance capability and enjoy greater alliance success, where firm‐level alliance success is measured in two ways: (a) abnormal stock market gains following alliance announcements and (b) managerial assessments of long term alliance performance; and (2) are the two alternate ways of assessing alliance success correlated? We find that firms with greater alliance experience and, more importantly, those that create a dedicated alliance function (with the intent of strategically coordinating alliance activity and capturing/disseminating alliance‐related knowledge) realize greater success with alliances. More specifically, firms with a dedicated alliance function achieve greater abnormal stock market gains (average of 1.35%) and report that 63 percent of alliances are successful whereas firms without an alliance function achieve much lower stock market gains (average of 0.18%) and only a 50 percent long‐term success rate. We also find a positive correlation between stock market‐based measures of alliance success and alliance success measured through managerial assessments. In addition to providing insights into the development of alliance capability among firms, this paper is one of the first to provide empirical support for the efficient markets argument by demonstrating that the initial stock market response to a key event positively correlates to the long‐term performance and value of the event.

Market Power, Industrial Concentration and Innovative Activity

This paper discusses the paradox between the positive effect of industrial concentration on R & D spending, and its non-positive effect on the number of innovations. Also, I analyze whether concentration has different effects on small- and large-firm R & D. The analysis shows that the positive effect of industrial concentration on R & D spending is at least as strong for small firms as it is for large firms within an industry, which indicates that the possession of market power is not in itself conducive to innovative effort. In addition, high concentration appears to be attended with a loss of efficiency in R & D spending.     

The Determinants of R & D Expenditures: A Study of the Canadian Biotechnology Industry

The relative importance of a multitude of factors forthe allocation of expenses towards R & D are assessedin an empirical study of the Canadian biotechnologyindustry. The results show that patent protection andstrategic alliances facilitate R & D spending. Theresults also show that early-stage firms spend agreater proportion of the expenditures on R & D, whilefirms engaged in R & D in platform technologies andfirms with high debt-equity ratios spend a lowerproportion of their expenditures on R & D. Demand pulland competition variables are insignificant factors. Finally, counter to our expectations, R & Dexpenditures are more intensive among firms engaged inR & D in areas in which consumer controversies are morepronounced.     

Capital Structure Theory: Evidence from European Property Companies' Capital Offerings

This study examines the stock price reactions on announcements of both equity and debt offerings by European property companies. The unique setting in which corporate tax rates vary between different countries enables us to test established theories in the field of capital structure. In accordance with theory, we find a negative price reaction on equity offering announcements, which is less severe for low-tax countries and positive price reactions on the announcements of debt offerings. Besides tax arguments, we also test alternative explanations by analyzing variations in stock reactions based on differences in the relative size of the issue, the pre-offer leverage, the underlying property types, and operational performance. The results show that corporate taxation, issue size, and operational performance are significant explanatory factors in the negative price reactions.     

The Role of Managerial Stock Option Programs in Governance: Evidence from REIT Stock Repurchases

This article examines the role of stock option programs and executive holdings of stock options in real estate investment trust (REIT) governance. We study the issue by analyzing how the market reaction to a stock repurchase announcement varies as a function of the individual REIT's governance structure. In particular, we examine how executive and employee stock option holdings influence the market reaction to a firm's announcement of a stock repurchase. Using a sample of REIT repurchase announcements, we find that the market reacts more favorably to announcements by firms where executives have larger option holdings and the chief executive officer is not entrenched. Our results with respect to the roles of stock option holdings of executives and nonexecutives differ from those reported for a cross-section of non-REIT firms. While we find evidence supporting the importance of executive stock options in aligning the incentives of management and reinforcing the positive signaling associated with a repurchase announcement, we find little evidence that the market views REIT repurchases as being used primarily to fund option exercise. We attribute these findings to greater dependence by REIT investors on internal governance mechanisms (such as stock option programs) as a result of regulatory restrictions that limit external monitoring such as hostile takeovers.     

Is R & D Financially Constrained? Theory and Evidence from Irish Manufacturing

We re-examine the effects of liquidity constraints on R & D investment. Inour theoretical section we extend the neoclassical framework of investmentin physical capital by introducing R & D and liquidity constraints. Weanalyse this issue empirically using firm-level data for R & D activemanufacturing firms in the Republic of Ireland. Our results provide evidencethat suggests that R & D investment is financially constrained. This is inline with previous studies of U.S. firms.     

The Long-Run Performance of REIT Stock Repurchases

This study investigates the long-horizon performance of open-market stock repurchases for real estate investment trusts (REITs). We develop a new methodology to model the autocorrelation of monthly returns into long-horizon buy-and-hold abnormal return estimators. Serial correlation can introduce bias (autocorrelation bias) because the bid-ask bounce may affect monthly returns for sample firms and non-sample firms in a different fashion. Previous long-horizon event studies have overlooked this source of bias. There is compelling evidence that the market underreacts to the stock repurchase announcements. The evidence holds for different measures of the variance and the effects of cross-correlation of abnormal returns. Results are also robust to the traditional buy-and-hold abnormal return and the wealth relative estimators. We investigate the nature of the underreaction and find strong support for the undervaluation hypothesis.     

R&D competition versus R&D cooperation in oligopolistic markets with evolving structure

This paper considers investment behavior of duopolistic firms subject to technological progress. It is assumed that initially both firms offer a homogeneous product, but after a stochastic waiting time they are able to implement a product innovation. Production capacities of both firms are product specific. It is shown that firms anticipate a future product innovation by under-investing (if the new product is a substitute to the established product) and higher profits, and over-investing (in case of complements) and lower profits, compared to the corresponding standard capital accumulation game. This anticipation effect is stronger in the case of R&D cooperation. Furthermore, since due to R&D cooperation firms introduce the new product at the same time, this leads to intensified competition and lower firm profits right after the new product has been introduced. In addition, we show that under R&D competition the firm that innovates first, overshoots in new-product capacity buildup in order to exploit its temporary monopoly position. Taking into account all these effects, the result is that, if the new product is neither a close substitute nor a strong complement of the established product, positive synergy effects in R&D cooperation are necessary to make it more profitable for firms than R&D competition.
