Choosing a transport contract over multiple periods

We offer a shipper and a carrier the choice among three contracts in which to frame their relationship. Both can also take recourse in the transport spot market. Demand and price on the spot market are dependent exogenous stochastic processes. We model the outcome of this endogenous choice of contract. The results, given in closed form, are different from those presented in the literature. Using numeric instances, we show how a choice is made and which contract would be preferred. Comparison on the variance of the economic returns are offered. The conclusions are applicable when the carrier is not capacity constrained.

The Impact of I.T. on the Degree of Outsourcing, the Number of Suppliers, and the Duration of Contracts

It has long been accepted within theinformation technology (IT) researchcommunity that IT should have a profoundimpact on industrial organization. However,there has been as yet on the changes to be expected in the design of firms or industries; rather, there is an apparently inconsistent collection of conjectures and analyses. We are now able to offer an integrative framework for describing the impacts of IT on an industrial organization. Our analyses generally support the "move to the middle" hypothesis that states that the impact of IT on the organization of economic activity is to lead to a greater degree of outsourcing where this increased outsourcing is done from fewer suppliers with whom the buyer has long-term relationships.

Evaluating Food Commodity Procurement Strategies

We use a case study approach to determine the primary factors affecting food manufacturers' commodity procurement decisions, as well as to examine the strategic nature of commodity procurement departments. The research fills a gap in both the commodity and procurement literature. A large literature exists on commodity marketing; however, very little exists on the topic of commodity procurement. Existing procurement literature tends to focus on non-commodity products rather than commodity products. The results suggest a model for the strategic role of commodity procurement departments within food manufacturers. The initial procurement strategy must be supply maintenance, which once accomplished, allows the commodity procurement department to progress to a profit-focused strategy, which is generally cost-based. Finally, the role of the commodity procurement department can expand by offering additional services to customers, such as designing promotional programs.Marketing,

Electronic government procurement adoption behavior amongst Malaysian SMEs

The aim of this study is to investigate the relationship between a model of electronic procurement (e-procurement) adoption behavior and the level of Government e-procurement adoption amongst Small Medium Enterprise (SME) in Malaysia. Data was collected through questionnaires that were distributed to SME selected randomly in all SME in Malaysia.The data were analyzed using factor analysis, reliability analysis, independent-sample t-test, descriptive statistics, Pearson Correlation and multiple regressions. Regression results reveals that ‘power’, ‘trust’ and ‘value’ have a positive relationship with the level of e-procurement adoption amongst SME in Malaysia.All dimensions, namely; the power of supplier, power of procurement, trust on supplier, trust on information technology, value of implementation system efficiency and value of cost efficiency were also correlated with the level of e-procurement adoption amongst SME. Past studies on e-procurement are beset by problems of buyer-seller relationship perspective.In addition, these studies are skewed towards Government-SME relationship perspective which the Government possesses more power than SME and provide a better incentive to educate and influence SME to adopt e-procurement.In investigation the relationship between a model of e-procurement adoption behavior and the level of Government e-procurement adoption amongst SME in Malaysia, this study also tries to provides recommendation to Malaysian government for improving the level of e-procurement adoption amongst SME

The Power of Networks: Integration and Financial Cooperative Performance

The purpose of this paper is to perform a cross-country survey of the level of integration of systems of financial cooperatives (FC) and its effect on measures of performance. We develop a classification scheme based on a theoretical framework that builds on published work using transaction cost economics (TCE) to explain integration of large numbers of financial cooperatives into networks. We identify three critical level of increasing integration we call respectively atomized systems, consensual networks and strategic networks. Further, we test some of the propositions that result from the theoretical framework on an international sample of financial cooperative systems. Based on this analysis we can conclude that: i) Integration is less (more) important is developing (more developed) countries and for very small (large) financial cooperatives as a determinant of efficiency. However, integration tends to reduce volatility of efficiency and performance regardless of development. ii) Integration appears to help control measure of managers' expense preferences that tend to affect performance of FC. iii) Despite high costs of running hub-like organizations in highly integrated system, these systems economize in bounded rationality and operate at lower costs that less integrated systems.Transaction cost economics, financial cooperatives, credit unions, networks, corporate governance, technical efficiency, x-efficiency

Optimal Dynamic Procurement Policies for a Storable Commodity with L\'evy Prices and Convex Holding Costs

In this paper we study a continuous time stochastic inventory model for a commodity traded in the spot market and whose supply purchase is affected by price and demand uncertainty. A firm aims at meeting a random demand of the commodity at a random time by maximizing total expected profits. We model the firm's optimal procurement problem as a singular stochastic control problem in which controls are nondecreasing processes and represent the cumulative investment made by the firm in the spot market (a so-called stochastic "monotone follower problem"). We assume a general exponential L\'evy process for the commodity's spot price, rather than the commonly used geometric Brownian motion, and general convex holding costs. We obtain necessary and sufficient first order conditions for optimality and we provide the optimal procurement policy in terms of a "base inventory" process; that is, a minimal time-dependent desirable inventory level that the firm's manager must reach at any time. In particular, in the case of linear holding costs and exponentially distributed demand, we are also able to obtain the explicit analytic form of the optimal policy and a probabilistic representation of the optimal revenue. The paper is completed by some computer drawings of the optimal inventory when spot prices are given by a geometric Brownian motion and by an exponential jump-diffusion process. In the first case we also make a numerical comparison between the value function and the revenue associated to the classical static "newsvendor" strategy.Comment: 28 pages, 3 figures; improved presentation, added new results and section

Multistage Stochastic Portfolio Optimisation in Deregulated Electricity Markets Using Linear Decision Rules

The deregulation of electricity markets increases the financial risk faced by retailers who procure electric energy on the spot market to meet their customers’ electricity demand. To hedge against this exposure, retailers often hold a portfolio of electricity derivative contracts. In this paper, we propose a multistage stochastic mean-variance optimisation model for the management of such a portfolio. To reduce computational complexity, we perform two approximations: stage-aggregation and linear decision rules (LDR). The LDR approach consists of restricting the set of decision rules to those affine in the history of the random parameters. When applied to mean-variance optimisation models, it leads to convex quadratic programs. Since their size grows typically only polynomially with the number of periods, they can be efficiently solved. Our numerical experiments illustrate the value of adaptivity inherent in the LDR method and its potential for enabling scalability to problems with many periods.OR in energy, electricity portfolio management, stochastic programming, risk management, linear decision rules
