Debt financing,first-mover advantage,and vertical product differentiation

This paper examines the impact of the strategic use of debt financing as a commitment device, in a vertically differentiated duopoly with demand uncertainty. We consider various possible game sequences for two firms with asymmetric financial structures to enter the market. The results show that (i) having access to external debt does not necessarily promote the firm to provide a higher quality product; (ii) strategic debt improves the degree of product differentiation and benefits both firms; and (iii) a firm's optimal debt level is positively related to the first-mover advantage of introducing its product to the market.     

Cost-based decision rules for output,quality, and price

The present paper develops a theoretical model to address the relationship between a firm's pricing policy and its cost of increasing product quality. The model expresses both firm costs and firm revenues as functions of the quantity of a firm's output and overall product quality, where quality is expressed as quantity times quality per unit. The model starts with a generic good that measures output, and models quality as priced quality enhancement for each unit of the generic good. The model leads to decision rules by which the price of quality is a mark-up over the marginal cost of increasing product quality. The relationship between the price of quality and revenues from increasing output is also determined, and is conditioned by the sign and magnitude of the elasticity of demand for quality.     

Optimizing order policy and credit term for items with inventory-level-dependent demand under trade credit limit

Under the combined effects of inventory-level-dependent demand (ILDD) and trade credit, the retailer is able to order more quantities to stimulate market demand. However, from the supplier's perspective, two important issues are lacking sufficient attention. First, during the credit period, the retailer's higher order quantities imply increases in both the retailer's account payable and the supplier's opportunity cost of capital. Second, given the supplier's fixed production rate, the increased market demand may drive the capacity utilization to be variable. Thus, by formulating a supplier-dominated system, this paper incorporates trade credit limit (TCL) to address its effects on optimal policies vis-à-vis the item with ILDD. Specifically, three indicators can be proposed to reveal which type of financing policy the retailer should choose. Moreover, based on TCL, the supplier can effectively manage the retailer's order quantity and the corresponding account payable. Additionally, the retailer's maximum allowable order quantity is developed to ensure that the supplier can supply the retailer's order quantity on time. Furthermore, when the effects of ILDD become more significant, the manufacturer will reduce the maximum allowable order quantity to control the retailer's order incentive.     

Learning in Advance Selling with Heterogeneous Consumers

Advance selling occurs when consumers order a firm's product prior to the regular selling season. It reduces uncertainty for both the firm and the buyers and enables the firm to better forecast its future demand. The distinctive feature of this paper is that there are both experienced and inexperienced consumers, with the former knowing their valuations of the product in advance. We show that pre‐orders from experienced consumers lead to a more precise forecast of future demand by the firm and that the optimal pre‐order price may be at a discount or a premium relative to the regular selling price.

Optimal Two‐part Pricing under Cost Uncertainty

This paper examines the optimal two‐part pricing under cost uncertainty. We consider a risk‐averse monopolistic firm that is subject to a cost shock to its constant marginal cost of production. The firm uses two‐part pricing to sell its output to a continuum of heterogeneous consumers. We show that the global and marginal effects of risk aversion on the firm's optimal two‐part pricing are to raise the unit price and lower the fixed payment. We further show that an increase in the fixed cost of production induces the firm to raise (lower) the unit price and lower (raise) the fixed payment under decreasing (increasing) absolute risk aversion. The firm's optimal two‐part pricing is unaffected by changes in the fixed cost under constant absolute risk aversion. Finally, we show that a mean‐preserving spread increase in cost uncertainty induces the firm to raise the unit price and lower the fixed payment under either decreasing or constant absolute risk aversion.

Managerial economics and operating beta

We model a firm's unlevered beta in terms of elementary microeconomic variables. The source of uncertainty is a shock to demand. A firm decides on capital before the shock, and on labor, output, and price after the shock. Some insights are: (1) with decreasing returns to scale of production, beta has an inverse relation with price elasticity of demand, given the income elasticity of demand; (2) beta has a direct relation with the firm's returns to scale of production; (3) due to the impact of operating leverage, beta has an inverse relation with industry concentration; and (4) for a given returns to scale, beta has a direct relation with the capital–labor ratio that strengthens as industry concentration decreases.

Managerial utility-maximizing operating decisions under compound demand risk

This paper examines the demand and cost conditions under which utility maximizing pricing-risk and advertising-risk relationships are determinate. The structure of the firm's demand uncertainty captures both uncertain customer arrivals and uncertain individual customer demand. In addition to standard demand restrictions and constant marginal cost, determinate results depend upon the degree of managerial risk-aversion, the correlation between individual demand and customer arrival disturbances, the firm's cost fixity, and bounded product differentiation effects of advertising. The symmetry between price-cuts and advertising as demand-increasing costs is extensively examined; firm equilibrium requires that price-cuts not be an inferior input for increasing demand.     

Learning by a dominant firm

This paper is concerned with the optimal output decisions of a dominant firm in the presence of imperfect information about the rival's reactions. The model is multi-period with the profits in each period being independent of those in other periods. Consequently, if the rival's reaction parameter were known to the dominant firm, a myopic policy would be optimal, In the presence of imperfect information about the rival's unknown reaction parameter, the dominant firm acts in a Bayesian manner by updating its prior distribution based on the observations of the rival's outputs. Because of the multiplicative shape of the rival's reaction function, the Bayesian updating rule is a function of the dominant firm's decision variable, i.e. its output decisions. This creates a dependence of the future value of the dominant firm on the present output decision, and hence a myopic policy is not, in general, optimal. It is shown that through output experimentation the dominant firm will tend to overproduce and, consequently, will increase its expected discounted profits (market value).     

How a Firm's Domestic Footprint and Domestic Environmental Uncertainties Jointly Shape Added Cultural Distances: The Roles of Resource Dependence and Headquarters Attention

Even though many firms conduct most of their business domestically, international management research has remained remarkably silent on the role of a firm's domestic footprint in its internationalization strategy. We shed light on that role by exploring how the size of a firm's domestic footprint influences the cultural distance that the firm adds to its country portfolio when expanding internationally. Integrating resource dependence theory and the attention‐based view, we hypothesize that a firm's domestic footprint has a negative relationship with added cultural distance (ACD), and that domestic policy uncertainty strengthens this relationship whereas domestic demand uncertainty weakens it. We find robust support for our hypotheses in a sample of the world's largest retailers covering the period 2000–07, indicating that a firm's domestic footprint and domestic environmental uncertainties jointly shape cross‐cultural expansion strategies. Our findings suggest that ACDs reflect headquarters executives' desire to avoid ineffective foreign expansions, hinting at possible biases in studies of the performance effects of distance.     

Price uncertainty and the effect of capital costs in a point in-point out inventory investment

This paper analyzes a point in-point out inventory investment under price uncertainty. The optimal quantity is determined by maximizing the expected value of the investor's risk preference function, which is a function of profit. Using an exponential risk preference function, the adjustment in the optimal quantity stemming from a change in the interest rate is investigated. The main conclusion is that the sign of the adjustment depends both on how profit is expressed and on the type of price distribution applied. Contrary to what is assumed in conventional managerial control practices, a rise in the interest rate might lead to an increase in the optimal quantity when present value serves as a measure of profit.     

Disclosure Policy in a Mixed Market

This paper investigates the optimal disclosure strategy for private information in a mixed duopoly market, where a state-owned enterprise (SOE) and a joint-stock company compete to supply products. I construct a model where the two firms compete in either quantity or price, and uncertainty is associated with either marginal cost or market demand. The model identifies the optimal disclosure strategies that constitute a perfect Bayesian equilibrium by type of competition and uncertainty. In Cournot competition, both firms disclose information under cost uncertainty, while only the SOE or neither firm discloses information under demand uncertainty. Alternatively, in Bertrand competition, only the joint-stock company discloses information under cost uncertainty or demand uncertainty. Recently, developed countries have required the same level of disclosure standards for SOEs as for ordinary joint-stock companies. The findings described in this paper warn that such mandatory disclosure by SOEs can trigger a reaction by joint-stock companies, putting the economy at risk of a reduction in welfare.     

Choosing the Quality of the Fit between Complementary Products

In this paper, I examine how firms should position their complementary products. I assume that there are two competing firms, each producing two complementary products. Each firm decides whether to employ strategies that enhance the quality of the fit (the degree of complementarity) between its pair of complementary products before competing in prices. The consumers have heterogeneous tastes for the four possible bundles. They are willing to pay a price premium in order to purchase a bundle from the same firm if this firm chose to make such bundle more attractive. I find that increasing the degree of complementarity between a firm's complementary products intensifies price competition and often leads to smaller profits. Only when complementarity‐enhancing strategies significantly increase the demand for a firm's matching bundle, does the firm benefit from employing them. The highest profits for both firms are obtained when both firms do not employ complementarity‐enhancing strategies. Deteriorating the quality of the fit between one's own and a rival's complementary products is never profitable.

Corporate sustainability and financial performance: Collective reputation as moderator of the relationship between environmental performance and firm market value

Markets value superior corporate sustainability performance in part because investors use a firm's environmental performance as a signal of desirable but difficult-to-observe attributes, such as the firm's integrity capacity. Yet a signaling conflict can arise when a firm belongs to an organizational form that has a collective reputation for being unethical. In such circumstances, the firm's environmental performance may no longer credibly signal its underlying integrity capacity, leading markets to adjust downward the value they would otherwise place on the firm's environmental performance. Using longitudinal data on South Korean firms, we find that improvements in firm environmental performance lead to smaller increases in market values for firms belonging to a poorly reputed organizational form. However, firms can partially recover lost value by adopting firm features that reduce the signaling conflict, thereby restoring the notion of corporate sustainability performance driving firm market values.     

New product introduction under demand uncertainty in competitive industries

A game-theoretic model is employed to examine the conditions under which firms in a duopoly, faced with a new product introduction opportunity of uncertain profitability (because of uncertainty in demand), choose to enter the market immediately or, alternatively, decide to wait, thereby avoiding the risk of failure. The implications for a firm's strategic behavior are contrasted with situations in which the competitor is believed to be (1) passive, implying that the firm expects to enjoy indefinite monopoly status if it introduces the new product, and (2) committed to a waiting strategy, implying monopoly status for a limited time period, if the new product is successful.     

Uncertainty,hiring and firing costs,and the determinants of profit‐sharing rules

We consider a firm run by a manager who acts on behalf of shareholders. The firm produces a commodity whose demand evolves stochastically over time. The firm's employees possess firm‐specific skills and knowledge and thus can bargain over profits with shareholders immediately before the firm hires or fires workers. The firm will distribute more portions of profits to employees when it incurs higher costs to hire or fire workers. In addition, as uncertainty in demand increases, the firm will distribute smaller (larger) portions of profits to employees if the firm does not have the option to fire (hire) workers.     

The Management of Creative Vision and the Economics of Creative Cycles

This paper proposes a new theory of variability in innovation performance in managerial firms that contract ‘creative vision’. We argue that such firms are prone to ‘creative cycles’ that arise from uncertainty‐induced systemic overshooting that can threaten the firm's financial viability, requiring managers to shift control back to risk‐averse financial controllers. But this creates opportunities for competing firms to engage in bold creative visions, threatening the firm's market viability and inducing control to shift back to newly contracted suppliers of ‘creative vision’. We discuss how this ‘principal‐agent‐agent’ mechanism plays out, the types of uncertainty that drive it, and consider the industry‐level externalities it induces.

Optimal structure of joint inventory-pricing management with dual suppliers and different lead times

We consider a joint inventory-pricing control problem in a single-product, periodic-review, dual-supplier inventory system. The two suppliers have different lead times. One expedited supplier offers instantaneous replenishment, and one regular supplier requires an L-period lead time for delivery. The supply quantity is stochastic and the demand is price-dependent. For the expedited inventory replenishment, we characterize the optimal policy as a state-dependent almost-threshold policy by extending the stochastically linear in mid-point to a multidimensional setting. To investigate the optimal regular inventory replenishment and pricing policy, we propose the notions of partially stochastic translation (PST) and increasing partially stochastic translation (IPST), which help in obtaining the antimultimodularity preservation in dynamic programming problems. We provide properties, sufficient conditions, and examples for PST and IPST functions. By applying PST and IPST, we obtain the antimultimodularity of the profit functions. The antimultimodular profit functions ensure that the optimal regular ordering quantity and the optimal price are monotone in the current inventory level and outstanding order quantities. Moreover, we reveal that as the time interval increases, the effects of previous outstanding orders on the optimal regular ordering and pricing decisions are decreasing and increasing, respectively. PST and IPST also enable us to further characterize the optimal expedited ordering quantity as decreasing in the inventory level. However, the optimal expedited ordering quantity can be non-monotone with respect to the outstanding order quantities, as shown in the example.
