Designing Efficient Infrastructural Investment and Asset Transfer Mechanisms in Humanitarian Supply Chains

We analyze the efficacy of different asset transfer mechanisms and provide policy recommendations for the design of humanitarian supply chains. As a part of their preparedness effort, humanitarian organizations often make decisions on resource investments ex ante because doing so allows for rapid response if an adverse event occurs. However, programs typically operate under funding constraints and donor earmarks with autonomous decision‐making authority resting with the local entities, which makes the design of efficient humanitarian supply chains a challenging problem. We formulate this problem in an agency setting with two independent aid programs, where different asset transfer mechanisms are considered and where investments in resources are of two types: primary resources that are needed for providing the aid and infrastructural investments that improve the operation of the aid program in using the primary resources. The primary resources are acquired from earmarked donations. We show that allowing aid programs the flexibility of transferring primary resources improves the efficiency of the system by yielding greater social welfare than when this flexibility does not exist. More importantly, we show that a central entity that can acquire primary resources from one program and sell them to the other program can further improve system efficiency by providing a mechanism that facilitates the transfer of primary resources and eliminates losses from gaming. This outcome is achieved without depriving the individual aid programs of their decision‐making autonomy while maintaining the constraints under which they operate. We find that outcomes with centralized resource transfer but decentralized infrastructural investments by the aid programs are the same as with a completely centralized system (where both resource transfer and infrastructural investments are centralized).     

Shattering the Myth of Costless Price Changes

Despite its centrality to the topic, very little attention has been paid to the topic of price changes. Indeed, for the most part, organisations operate under the myth of costless price changes. This article broadens the definition of the costs of changing price and then presents strategic recommendations for improving the way in which prices are changed within organisations.     

Optimal Order Quantities with Remanufacturing Across New Product Generations

We address the problem of determining the optimal retailer order quantities from a manufacturer who makes new products in conjunction with ordering remanufactured products from a remanufacturer using used and unsold products from the previous product generation. Specifically, we determine the optimal order quantity by the retailer for four systems of decision‐making: (a) the three firms make their decisions in a coordinated fashion, (b) the retailer acts independently while the manufacturer and remanufacturer coordinate their decisions, (c) the remanufacturer acts independently while the retailer and manufacturer coordinate their decisions, and (d) all three firms act independently. We model the four options described above as centralized or decentralized decision‐making systems with the manufacturer being the Stackelberg leader and provide insights into the optimal order quantities. Coordination mechanisms are then provided which enable the different players to achieve jointly the equivalent profits in a coordinated channel.     

Identifiability of two‐component skew normal mixtures with one known component

We give sufficient identifiability conditions for estimating mixing proportions in two‐component mixtures of skew normal distributions with one known component. We consider the univariate case and two multivariate extensions: a multivariate skew normal distribution (MSN) and the canonical fundamental skew normal distribution (CFUSN). The characteristic function of the CFUSN distribution is additionally derived.     

Cost‐Reducing Innovation and the Role of Patent Intermediaries in Increasing Market Efficiency

Patent intermediaries have gained importance as non‐practicing entities in the innovation domain, buying innovations from an external provider and then licensing them to practicing firms. In this study, we analyze the competition between two identical incumbent firms and a patent intermediary for the acquisition and licensing of a cost‐reducing innovation developed by an external innovator. We show that the outcome of the IP acquisition and licensing game critically depends on the degree of the cost‐reducing innovation. Patent intermediaries win IP rights in patent markets if the innovation is incremental. They also win the IP rights when the innovation is moderate or radical, providing they have significant efficiency advantages over incumbent firms and the uncertainty about the degree of innovation is low. We also show that patent intermediaries serve to make markets more efficient. When the innovation is incremental or moderate, they help ensure a lower cost of production and a lower price for customers, and when the innovation is radical, they help increase the profits of the incumbent firms.     

Lifecycle Pricing for Installed Base Management with Constrained Capacity and Remanufacturing

Installed base management is the policy in which the manufacturer leases the product to consumers, and bundles repair and maintenance services along with the product. In this article, we investigate for the optimal leasing price and leasing duration decisions by a monopolist when the production and servicing capacity are constrained. The effect of diffusion of consumers in the installed base is considered, with the ownership of the product resting with the monopolist during the product lifecycle. The monopolist operating the installed base jointly optimizes the profits from leasing the product/service bundle along with maintenance revenues and remanufacturing savings. We formulate the manufacturer's problem as an optimal control problem and show that the optimal pricing strategy of the firm should be a skimming strategy. We also find that the effect of remanufacturing savings on the pricing decision and the length of the leasing duration changes significantly depending on the duration of the product's lifecycle. If the product lifecycle is long and remanufacturing savings are low, the firm should offer a shorter leasing duration, whereas if the remanufacturing savings are high, the firm should optimally offer a higher leasing duration. In contrast, if the time duration of the product lifecycle is low and remanufacturing savings are low, the firm prefers to offer a shorter leasing duration, whereas if the remanufacturing savings are high, the firm should optimally have a longer leasing duration. The article also shows that if the production capacity is small, the manufacturer increases the leasing duration. If the production capacity is very small, the manufacturer sets the leasing duration to be equal to the product lifecycle and does not use remanufacturing.
