Explaining underpricing of IPOs in frontier markets: Evidence from the Nigeria Stock Exchange

The paper provides empirical analyses of IPO underpricing on the Nigerian Stock Exchange, from the period 1990 to 2006. The results indicate an average abnormal initial day returns of 43.1%. There is evidence of long-run underperformance of 0.6%. Results from our regression model explaining initial abnormal returns for the IPOs of Nigeria show that size of firm and audit quality are important variables affecting underpricing. The results also show the presence of a non-linear relationship between the offer price and underpricing.     

Quantification of Operational Risk: A Scenario-Based Approach

In this article, I identify challenges to the loss distribution approach in modeling operational risk. I propose a scenario-based methodology for operational risk assessment, which recognizes that each risk can occur under a number of wide-ranging scenarios and that association between risks may behave differently for different scenarios. The model that is developed internally in the company provides a practical quantitative assessment of risk exposure that reflects a deep understanding of the company and its environment, making the risk calculation more responsive to the actual state, ensuring that the company is attending to its key operational risks. In this model qualitative and quantitative approaches are combined to build a loss distribution for individual and aggregate operational risk exposure. The model helps to portray the company's internal control systems and aspects of business environment. These features can help the company increase its operational efficiency, reduce loss from undesirable incidents, and maintain the integrity of internal control.     

The investment decision with technological and market uncertainties

This paper examines how technological uncertainty affects current investment; specifically, what is the impact on a firm’s investment in an existing technology when an improved technology might arrive in the future. The firm can invest in the current technology and upgrade to the new technology after its arrival (sequential investing), or it can bypass the current technology and invest directly in the new technology (leapfrogging). The main result is that, in the presence of market risk, future technological uncertainty has a non-monotonic effect on investment, with the investment trigger being a U-shaped function of the expected speed of arrival of the new technology. In this U-shaped relationship, the investment trigger starts rising later if the new technology is more attractive and also when volatility and interest rate are high and growth rate low; thus, technological uncertainty is more likely to have a positive effect on investment under these conditions. Finally, we apply the model to the sequential versus leapfrog investment decision, and find that leapfrogging becomes more attractive relative to sequential investment when interest rate and new technology earnings enhancement are higher, and when market volatility, growth rate and new technology investment cost are lower.     

Agency cost of debt overhang with optimal investment timing and size

The concept of debt overhang (that is, an equity‐maximizing levered firm will under‐invest relative to a firm‐value‐maximizing firm) is well established in the literature. A number of papers have demonstrated it as delayed investment (when investment size is specified) or smaller investment (when investment time is specified). However, there is no work on the underinvestment effect when the firm chooses both size and timing of investment, as it usually does in real life. This is what our paper focuses on. When the firm has the flexibility to choose both size and time, the effect is complicated by the fact that delayed investment results in larger investment, which suggests that the underinvestment problem might be mitigated. We find, however, that the effect depends on how underinvestment is measured. When measured by the expected present value of investment, flexibility can mitigate or exacerbate the underinvestment problem, depending on the cost of installing capacity. But when measured by the agency cost, flexibility always exacerbates the underinvestment problem. It is shown numerically that, at the optimal leverage ratio, the agency cost with plausible parameter values can be economically significant. Thus, with the flexibility of choosing both time and size of investment, the debt overhang problem can be of significant practical relevance in corporate investment decisions.     

Market response to dividend change announcements: unregulated versus regulated US firms

This paper attempts to determine whether there is a significant difference in how the stock market responds to dividend change announcements of regulated (both utilities and financials) versus unregulated firms and, if so, which factors cause this difference. An analysis of dividend change announcements of US firms over the period 1962–2016 shows that the market response is larger for unregulated than for regulated firms, but this difference is statistically significant only for dividend increases (not for dividend decreases). Further, cross-sectional analysis indicates that, for dividend increases, the difference between regulated and unregulated firms increases with diffused ownership and informational asymmetry. When both these factors are controlled for, the difference between regulated and unregulated firms becomes statistically insignificant. Thus, the evidence suggests that the significant difference in market response to dividend increases of regulated versus unregulated firms can be explained by differences in diffused ownership and informational asymmetry. There seems to be no intrinsic difference between regulated and unregulated firms in the market response to dividend decreases.     

Analysis of multiple response in marketing research: Estimating the degree of association

Researchers often are forced to analyze nominally-scaled multiple response questions for which respondents have provided more than one response. A Multiple Index of Predictive Association (MIPA) is derived for estimating the effect of the independent variable on the dependent variable when one or both variables have multiple responses. MIPA is illustrated using demographic and preference data. The relevance of the Multiple Index of Predictive Association to marketing and its implications are discussed.     

MARTINGALE APPROACH TO PRICING PERPETUAL AMERICAN OPTIONS ON TWO STOCKS

We study the pricing of American options on two stocks without expiration date and with payoff functions which are positively homogeneous with respect to the two stock prices. Examples of such options are the perpetuai Margrabe option, whose payoff is the amount by which one stock outperforms the other, and the perpetual maximum option, whose payoff is the maximum of the two stock prices Our approach to pricing such options is to take advantage of their stationary nature and apply the optional sampling theorem to two martingales constructed with respect to the risk-neutral measure the optimal exercise boundaries, which do not vary with respect to the time variable, are determined by the smooth pasting or high contact condition the martingale approach avoids the use of differential equations.     

Do Trademark Infringement Lawsuits Affect Brand Value: A Stock Market Perspective

Many firms find that they can benefit from copying orotherwise misusing the trademarks of their competitors. Firmsthat have maintained a positive brand image are likely to fightany dilution or eventual loss of their trademark by using lawsuitsagainst offending firms. These lawsuits help to staunch any lossesto the brand and leave the potential for the benefits from thetrademark to flow back to the firm. These benefits will be temperedby legal costs, potential infringement by other firms in futureand the need to file lawsuits in response. In contrast, firmsthat have infringed on a trademark are likely to lose if theowner of the trademark challenges them in court. This study relatesthe stock returns of firms to the filing of lawsuits to defendtrademarks. We study the impact of both the filing of the lawsuitand the eventual verdict of the court on the stock market valueof defendant and plaintiff firms. The protection of a trademarkby a plaintiff using a lawsuit resulted in a negative returnto the shareholders of the defendant firm that infringed on thetrademark. The returns to the plaintiff firms were mixed andof marginal magnitude due to offsetting factors although largefirms experienced positive returns.
