Abstract

Contrary to its highest R&D intensity, Japan has dramatically decreased its productivity in the 1990s. This can be attributed to a low marginal productivity of technology. Such a productivity decrease compels a delay in R&D, which results in reduced R&D productivity leading to a vicious cycle between R&D and its return. In this context optimal timing of R&D is crucial, particularly during economic stagnation and consequent difficulties in financing R&D. This paper analyzes the rationale for optimal timing of R&D and its interacting relationship with marginal productivity of technology. Empirical analyses are attempted focusing on Japan’s leading high‐technology firms and their innovative products.

Abstract

Purpose

The objective of this paper is twofold: first, to model the value of the firm in the presence of contingent capital and multiple growth options over its life cycle in a stochastic universe to ensure financial stability and recover losses in case of default and second, to clarify how contingent convertible (CoCo) bonds as financial instruments impact the leverage-ratio policies, inefficiencies generated by debt overhang and asset substitution for a firm that has multiple growth options. Additionally, what is its impact on investment timing, capital structure and asset volatility?

Design/methodology/approach

The current paper elaborates the modeling of a dynamic problem with respect to the interaction between funding and investment policies during multiple sequential investment cycles simultaneously with dynamic funding. The authors model the value of the firm in the presence of contingent capital that provides flexibility in dealing with default risks as well as growth options in a stochastic universe. The authors examine the firm's closed-form solutions at each stage of its decision-making process before and after the exercise of the growth options (with and without conversion of CoCo) through applying the backward indication method and the risk-neutral pricing theory.

Findings

The numerical results show that inefficiencies related to debt overhang and asset substitution can go down with a higher conversion ratio and a larger number of growth options. Additionally, the authors’ analysis reveals that the firm systematically opts for conservative leverage to minimize the effect of debt overhang on decisions so as to exercise growth options in the future. However, the capital structure of the firm has a substantial effect on the leverage ratio and the asset substitution. In fact, the effect of the leverage ratio and the risk-shifting incentive will be greater when the capital structure changes during the firm's decision-making process. Contrarily to traditional corporate finance theory, the study displays that the value of the firm before the investment expansion decreases and then increases with asset volatility, instead of decreasing overall with asset volatility.

Research limitations/implications

The study’s findings reveal that funding, default and conversion decisions have crucial implications on growth option exercise decisions and leverage ratio policy. The model also shows that the firm consistently chooses conservative leverage to reduce the effect of debt overhang on decisions to exercise growth options in the future. The risk-shifting incentive and the debt overhang inefficiency basically decrease with a higher conversion ratio and multiple growth options. However, the effect of the leverage ratio and the risk-shifting incentive will be greater when the capital structure changes during the firm's decision-making process.

Originality/value

The firm's composition between assets in place and growth options evolves endogenously with its investment opportunity and growth option financing, as well as its default decision. In contrast to the standard capital structure models of Leland (1994), the model reveals that both exogenous conversion decisions and endogenous default decisions have significant implications for firms' growth option exercise decisions and debt policies. The model induces some predictions about the dynamics of the firm's choice of leverage as well as the link between the dynamics of leverage and the firm's life cycle.

Abstract

In this paper, we view an individual's annuitization decision as an American style call option whose underlying asset is financial wealth, which controls the distance to annuitization. We then derive a certain threshold of wealth over which the individual is optimal to annuitize all of her wealth. We particularly focus on the effects of liquidity constraints on the individual's optimal annuitization decision, concerning their effects on the optimal investment and consumption strategies. We show that the annuitization decision can be significantly affected by the extent to which individual borrowing is constrained. More specifically, the optimal decision is for the individual to annuitize earlier with the tighter liquidity constrains she is exposed to than initially planned. This is particularly relevant to today's pandemic situation especially with the growing concern about cutting credit limits.

Abstract

Purpose

This paper aims to examine the optimal promotion strategy of an e-retailer, who may advertise, or launch rebates initiative to encourage consumers' disseminating electronic word-of-mouth (eWOM) messages, with an aim to boost product sales.

Design/methodology/approach

This paper analyzes the decisions of the e-retailer in a two-period model, using utility function approach and backward induction method, and obtains the optimal solutions in four promotion strategies.

Findings

The study finds that rebate scheme greatly impacts the timing of advertising, and neither lower nor higher consumers' eWOM effort invariably benefits the retailer, rather, a medium level is the best choice for the retailer. When eWOM impact power is at a relatively high level, it can supplement advertising effect to attract more consumers' purchase. Otherwise, eWOM may counteract the role of advertising.

Originality/value

Different from the extant literature focusing on advertising or eWOM without rebates, the paper studies the issue of advertising and eWOM with rebates in two- period model which seldom addresses before the authors examine the optimal timing of advertising and eWOM with/without rebates in four promotion strategies i.e. the A-NE model the NE-A model the A-ER model and the ER-A model.

Abstract

Current US tax laws provide investors an incentive to time the sales of their bonds to minimize tax liability. This gives rise to a tax-timing option that affects bond value. In reality, corporate bond investors’ tax-timing strategy is complicated by risk of default. Existing term structure models have ignored the effect of the tax-timing option, and how much corporate bond value is due to the tax-timing option is unknown. In this chapter, we assess the effects of taxes and stochastic interest rates on the timing option value and equilibrium price of corporate bonds by considering discount and premium amortization, multiple trading dates, transaction costs, and changes in the level and volatility of interest rates. We find that the value of the tax-timing option accounts for a substantial proportion of corporate bond price even when interest rate volatility is low. Ignoring the timing option value results in overestimation of credit spread, and underestimation of default probability and the marginal investor’s income tax rate. These estimation biases generally increase with bond maturity and credit risk.

Abstract

Purpose

The “supply-side effect” brought about by the imperfection of the capital market has increasingly been concerned. The purpose of this paper is to study how will the uncertainty of equity financing brought about by the equity financing regulations in emerging capital market affect company's capital structure decisions.

Design/methodology/approach

This paper establishes a theoretical model and tries to introduce equity financing uncertainty into the company's capital structure decision-making. The paper uses mathematical derivation method to get some basic conclusions. Next, in order to characterize the quantitative impact of specific factor on capital structure, numerical solution methods are used.

Findings

The model shows that firm's value would decrease with the uncertainty of equity financing, because of the relationship between firm's future cash and their financing policies. The numerical solution of the model suggests that the uncertainty of equity financing is one of the important factors affecting the choice of optimal capital structure, the greater the uncertainty is, the lower optimal capital structure is.

Originality/value

The research of this paper has certain academic value for further understanding of the issues.

Abstract

We consider the partial hedging of stochastic electricity load pattern with static forward strategies. We assume that the company under consideration maximizes the risk adjusted expected value of its electricity cash flows. First, we calculate an optimal hedge ratio and after that we use this hedge ratio to solve the optimal hedging time. Our results indicate, for instance that agents with high load volatility hedge later than agents that have low load volatility. Moreover, negative correlation between forwards and electricity load pattern postpones the hedging timing.

Abstract

Purpose

The existence of the advertising delay effect and its impact on supply chain operations have been demonstrated in the current study. Therefore, this study develops a timely inventory control strategy for the fresh produce supply chain to address the advertising delay effect in the fresh produce supply chain.

Design/methodology/approach

This study proposes a game model based on the Nerlove-Arrow time delay differential equation and Pontryagin's maximum principle. Through comparative analyses of the optimal equilibrium strategies, the authors compare the optimal equilibrium strategies, product goodwill and optimal inventory trajectories for suppliers and retailers under secondary replenishment decisions and decentralized decisions.

Findings

The authors find that (1) Only when the sales cycle meets certain conditions can the overall profit of the supply chain under the secondary replenishment decision be greater than that under the decentralized decision. As the price markup coefficient increases, the total profit of the supply chain first increases and then decreases. (2) With the increase in the delay time, the replenishment quantity during the initial period gradually decreases. After the delay time elapses, the inventory depletion rate under secondary replenishment decisions is faster than that under decentralized decision-making. (3) Although there is a continuously increasing maximum value of product goodwill with the increase in delay time, it becomes difficult to achieve this value for longer delays.

Practical implications

The authors’ findings provide a theoretical basis for supply chain members of fresh agricultural products to select replenishment and inventory control strategies when adopting different levels of delay in advertising marketing.

Originality/value

Firstly, this paper explains the impact of advertising delay effect on fresh produce supply chain from a dynamic perspective, and secondly, it provides guidance on advertising formulation and inventory replenishment for fresh produce retailers under the influence of advertising delay effect.

Abstract

Purpose

Reasonable remuneration of employee inventions is a controversial issue causing court litigations among employees and employers in many countries. The paper aims to shed light on the missing economic interpretation of the reasonable remuneration of employee inventions. Specifically, it focuses on the concept of “reasonability” at the issue.

Design/methodology/approach

In an empirical qualitative multiple case-study setting, the paper explores inductively Czech corporate employee inventors' remuneration systems, using typological analysis and M. Weber's interpretative theoretical construct of “ideal type.”

Findings

At the first level, reasonability is a function of multi-amount rewarding, a certain level of total remuneration and identifiable benefits being a decisive factor. Additionally, the reasonability is conceptualised as a function of two dimensions – timing/risk and benefit–reward relation. At the second level, the reasonability is interpreted as a concept balancing seven points of view: timing, materiality, equity, risk management, transparency, system costs and exactness. At the third level, the paper offers an optimal remuneration system like the one that optimises developed seven-criterion framework.

Research limitations/implications

Even if analysed within one-country and nine-company context, the insights are generalisable across a broader sample of countries with statutory rules for employee inventions. Studying more cases may enrich the findings. The findings are based merely on a rational perspective and do not deal with psychological aspects of employees.

Practical implications

The results may be helpful for intellectual property or R&D managers in building or reorganising employee invention remuneration systems within corporations. The developed seven-criteria model can serve as a discussion framework; the suggested optimal system as a reference point. The results may serve as well to consultants, judges or other parties involved in currently growing employee–employer controversies and litigations. The analysis may fuel public policy decisions, too.

Originality/value

The paper brings unique and detailed empirical insights into the issue of employee inventions. It offers a complex multi-perspective (employee/employer) framework through which the reasonability can be discussed and suggests an optimal system, which can serve as a reference point.
