The impact of capacity expansion on the market value of the firm

This paper empirically investigates the impact of capacity expansion decisions on the market value of the firm. Event study methodology is used to estimate the abnormal change in stock prices around capacity expansion decision announcements. On the day of the announcement, the magnitude of the price change is abnormally high, evidenced by a significantly positive mean standardized square of the abnormal change (Beaver's U-statistic). We also analyze factors that we could affect the direction and magnitude of the abnormal change in the stock prices. We find that the change in price on the day of the announcement is positively and significantly related to the real growth rate of the industry, and negatively and significantly related to the variability of demand. A negative relationship between the price change and industry capacity utilization is also found which can have important implications for companies which follow the wait-and-see approach to capacity expansion decisions. We also find management ownership to be a significant predictor in explaining stock price changes around these announcements.     

Developing Dividend and Financing Policies with a Computer Terminal

This study examines the value relevance of mandated disclosures by UK firms of the investor‐firm share of liabilities of equity‐accounted associate and joint venture investees. It does so for the six years following the introduction of FRS 9: Associates and Joint Ventures, which forced a substantial increase in such disclosures by UK firms. Since the increased disclosure requirements were partly motivated by concern that single‐line equity accounting concealed the level of group gearing, and in light of previous US results, it is predicted that the mandated investee‐liability disclosures have a negative coefficient in a value‐relevance regression. The study also examines whether value‐relevance regression coefficients on investee‐liability disclosures are more negative for joint ventures than for associates and whether they are more negative in the presence of investor‐firm guarantees of investee‐firm obligations than in the absence of such guarantees. The study reports that the coefficient on all investee‐liability disclosures taken together has the predicted negative sign, and is significantly different from zero. It finds little evidence that the negative valuation impact of liability disclosures is stronger for joint venture investees overall than for associate investees overall, or stronger for guarantee cases overall than for non‐guarantee cases overall. There is, however, some evidence that the impact for joint venture guarantee cases is stronger than that for joint venture non‐guarantee cases and stronger than that for associate guarantee cases.     

Bankruptcy risk,costs and corporate diversification

This paper studies the impact of diversification on firms that file for Chapter 11 bankruptcy. Prior research suggests that diversification affects both the probability and costs of distress. Treating bankruptcy as a special case of distress, we find that diversification reduces the likelihood of bankruptcy and liquidation in Chapter 11, which is consistent with the coinsurance hypothesis. However, we observe higher bankruptcy costs as measured by time spent in Chapter 11 and inefficient segment investment for diversified firms. Our evidence is consistent with the idea that diversification provides benefits to managers in terms of job security rather than to firms. Our findings may help firms to make diversification decisions and creditors determine lending policies toward different forms of organizations.     

A critical evaluation of alternative methods and paradigms for conducting mediation analysis in operations management research

Mediation as a theory testing approach has witnessed considerable adoption among Operations Management (OM) researchers. Although mediation-testing methods have evolved tremendously in the past decade, their dissemination in the OM field has not seen parallel growth. These advanced techniques facilitate the testing of existing and complex hypotheses in a more precise manner. With the intent of critically evaluating existing and alternative methods for conducting mediation analysis needed to support sophisticated empirical research, this paper first reviews OM studies that tested for mediation in the past eleven years (2002–2012) from top-tier OM journals. Four commonly used mediation approaches were identified. Based on principles of good theory building, type of mediation model, and properties of empirical data, we evaluate the existing methodologies and make recommendations on how to improve the rigor of OM mediation testing. Using published OM studies in top journals as examples, we then illustrate the relevance and advantages of these recommendations, as well as their ease of use. Furthermore, we empirically show that more robust and insightful results can be achieved by adopting these techniques, which in turn have the promise of leading to better theory building and testing in the field of operations management.     

An empirical investigation of environmental performance and the market value of the firm

This paper analyzes the shareholder value effects of environmental performance by measuring the stock market reaction associated with announcements of environmental performance. We examine the market reaction to two categories of environmental performance. The first category includes 417 announcements of Corporate Environmental Initiatives (CEIs) that provide information about self-reported corporate efforts to avoid, mitigate, or offset the environmental impacts of the firm's products, services, or processes. The second category includes 363 announcements of Environmental Awards and Certifications (EACs) that provide information about recognition granted by third-parties specifically for environmental performance. Although the market does not react significantly to the aggregated CEI and EAC announcements, we find statistically significant market reactions for certain CEI and EAC subcategories. Specifically, announcements of philanthropic gifts for environmental causes are associated with significant positive market reaction, voluntary emission reductions are associated with significant negative market reaction, and ISO 14001 certifications are associated with significant positive market reaction. The difference between the market reactions to the CEI and EAC categories is statistically insignificant. Overall, the market is selective in reacting to announcements of environmental performance with certain types of announcements even valued negatively.     

Tiered Housing Allocation with Preannounced Rankings: An Experimental Analysis

We study in the laboratory a variant of the house allocation with existing tenants problem where subjects are partitioned into tiers with hierarchical privileges, and they know their position in the priority queue before making their decision. We evaluate the performance of the modified versions of three well‐known mechanisms: Top Trading Cycle (TTC), Gale‐Shapley, and Random Serial Dictatorship (RSD) with Squatting Rights. For all three mechanisms, we find low rates of participation (around 40%), high rates of truth‐telling conditional on participation (around 90%), high proportions of fair allocations (above 90%), and significant efficiency losses. We also observe differences across mechanisms: RSD is ranked highest in efficiency and TTC is ranked lowest in fairness. We then show that position in the queue has a positive and significant impact on participation whereas tier has little effect on behavior. Finally, the individual analysis reveals that the majority of subjects who do not play according to the theory still follow discernible patterns of participation and preference revelation.     

Service levels for priority and nonpriority products with a common component

This paper refers to an article by Baker, recently published in the Journal of Operations Management. We point out an error, and provide correction, in the calculation of service level for a non priority product when a priority product and the nonpriority product share a common component.     

Special interest groups and the allocation of public funds

I propose a fully rational model of government contracting that explains differences in local government spending from grants and other income. In this model, violations of fungibility arise from dynamic interactions between politicians and interest groups with the ability to raise funds for the local government. The predictions of the model are tested by exploiting unique features of windfalls received by states under a settlement with the tobacco industry. Although windfalls are legally unrestricted, the median state increased spending on tobacco control programs from zero to $2.30 per capita upon receipt of funds. The marginal propensity to spend on such programs is 0.20 from settlement revenue and zero from overall income. States which were not involved in the settlement lawsuits spend less. These results cannot be explained by existing models in the literature.     

Opportunities for developing the science of operations and supply-chain management

In a separate paper (Singhal and Singhal, 2011b), we identified two sets of opportunities for radical innovations in operations and supply-chain management (O&SCM): pursuing all phases of science and pursuing multiple perspectives. In this paper, we propose and analyze ways to accomplish this task. A network of research teams can be effective in obtaining multiple perspectives and discovering radical innovation if it conducts intensive research over an extended period. Outliers are a source of multiple perspectives and innovative ideas and can help in identifying and addressing risks. Similarly, meta-analyses and syntheses of published works can provide multiple perspectives and lead to radical innovations.
