THE ROLE OF LOGISTICS MANAGERS IN THE CROSS‐FUNCTIONAL IMPLEMENTATION OF SUPPLY CHAIN MANAGEMENT

There is confusion about the domain of supply chain management, and the functions and processes that should be included. In this paper, we describe the key supply chain management processes, the role of logistics managers in each of these processes, and what the logistics function gains from this involvement.     

A STEP TOWARD DEFINING A CUSTOMER‐CENTRIC TAXONOMY FOR MANAGING LOGISTICS PERSONNEL

To retain competitive viability, some progressive warehouses and distribution centers are expanding services and adopting a customer orientation. Through cluster and ANOVA analyses, three distinct classifications of frontline logistics managers are disclosed and compared with respect to their perceived levels of internal customer orientation toward their subordinates, common performance indicators, and other demographic and organizational‐type variables. Important differences exist among the groups; however, logistics managers in all three clusters score relatively well in most areas explored.     

EFFECTS OF ORGANIZATIONAL LEARNING IN THIRD‐PARTY LOGISTICS

Logistics service providers operate in an intense competitive environment that requires continuous improvement in logistics service quality and firm performance. Key organizational resources may contribute toward the improvement in performance of logistics service providers. This paper investigates the effect of organizational learning within logistics service providers on client relationship orientation, logistics service quality and firm performance. The study proposes and examines an original concept in logistics research that contributes to theory in the area, provides the opportunity for further research and addresses how organizational resources can contribute to performance in logistics.     

LOGISTICS INNOVATION: A CUSTOMER VALUE‐ORIENTED SOCIAL PROCESS

This paper reports on a qualitative, grounded theory research project conducted in the United States, Sweden, and The United Kingdom designed to explore logistics innovation as perceived by leaders of logistics service provider firms and logistics business functions within product focused firms. Analysis of 33 depth interviews conducted within seven organizations revealed activities that reflect multiple aspects of being innovative, including: (1) setting a stage for innovation; (2) identifying clues to shifts in what customers value; (3) negotiating, clarifying, and reflecting upon insights; and (4) managing inter‐organizational learning.     

INTEREST RATE,DEBT, DISTRIBUTION AND CAPITAL ACCUMULATION IN A POST‐KALECKIAN MODEL

In the present paper we extend Lavoie's (Metroeconomica, 1995, vol. 46, pp. 146–177) ‘Minsky–Steindl’ model, building our analysis on a Kaleckian distribution and growth model which has already taken into account distribution effects of interest rate variations on the short‐run equilibrium. Into this model the effects of debt and debt services are explicitly introduced and the effects of interest rate variations on the short‐ and the long‐run equilibrium are derived. It is shown that the effects of interest rate variations on the endogenously determined equilibrium values of the model not only depend on the parameter values in the saving and investment functions but also on the interest elasticity of distribution and on initial conditions with respect to the interest rate and the debt–capital ratio.     

A POST‐KEYNESIAN STOCK‐FLOW CONSISTENT MODEL FOR DYNAMIC ANALYSIS OF MONETARY POLICY SHOCK ON BANKING BEHAVIOUR

We try to make Keynes' approach compatible with an endogenous theory of the money supply. For that purpose, the principle of liquidity preference is generalized within a competitive banking framework. Private banks can impose a monetary rationing independently of the central bank. Then, we analyse the consequences of a monetary policy shock on the financial behaviour of banks. We clarify the dynamic process between the monetary policy and net investment within a Minskyan approach. First, we build a Post‐Keynesian stock‐flow consistent model with a private‐bank sector introducing more realistic features. Second, we perform some simulations.     

THE PURCHASING‐LOGISTICS INTERFACE: A “SCOPE OF RESPONSIBILITY” TAXONOMY

To date, integration research has paid little attention to defining and exploring the interface between purchasing and logistics. This research seeks to catalog the set of joint activities that define this interface, and to analyze the way in which this interface is structured, in terms of how companies assign collective responsibility across the activity set. A cluster analysis of a set of 15 boundary‐spanning activities reveals a preliminary taxonomy of three purchasing‐logistics interface structures: (a) Purchasing‐Dominant; (b) Segregated; and (c) Logistics‐Dominant. The analysis also reveals limited evidence that the choice of purchasing‐logistic interface structure has an influence on supply base performance. In addition, the choice of purchasing‐logistics interface structure appears to be influenced by firm size.     

CUSTOMER SERVICE IN THE INTERNET‐ENABLED LOGISTICS SUPPLY CHAIN: WEBSITE DESIGN ANTECEDENTS AND LOYALTY EFFECTS

This article extends the existing research on logistics customer service‐loyalty relationships to the online logistics supply chain environment by examining potential website determinants of logistics customer service quality. A structural equation analysis of 373 online shopping transactions suggests that perceived quality of all logistics customer service activities (perceived cycle time, in‐stock availability, and customer responsiveness) varies inversely with: (1) perceived ease of use, and (2) content vividness of the website; and positively with product information content. However, only retailer customer responsiveness assessment was found to have any significant influence on consumer intended loyalty behavior in Internet‐enabled supplies chains.     

WAGE POLICY IN AN OPEN‐ECONOMY KALECKI–KALDOR MODEL: A SIMULATION STUDY

This paper discusses a Post‐Keynesian model of income, production and trade. The one‐country, one‐sector model features Kaleckian investment demand, Kaldorian productivity and a labor market module based on a wage–price spiral. The model is first presented for a closed economy with exogenous real wages; second, for a closed economy with endogenous real wages; third, for an economy open to trade with endogenous real wages. Simulations with different calibrations show key characteristics of the model. Monte Carlo simulations over reasonable parameter ranges shed some light on the effectiveness of wage policies in open economies.     

INTERNATIONAL RESERVE MANAGEMENT: A DRIFT‐SWITCHING REFLECTED JUMP‐DIFFUSION MODEL

We study the cost of shocks, that is, jump risk, with respect to reserve management when the reserve process is formulated as a drift‐switching jump diffusion with a reflecting barrier at 0. Inspired by the Brownian drift switching model, our model results in a more realistic dynamic behavior of international reserves than the buffer stock model. The new model can capture both the jump behavior in reserve dynamics and the leptokurtic feature of the increment distribution which has a higher peak and two asymmetric heavier tails than the normal distribution. Through the selection of an initial distribution that reflects certain steady state behaviors, the reserve process becomes a regenerative process. This selection enables us to derive a closed‐form expression for the total expected discounted cost of managing reserves, thus helping us to numerically find management strategies that minimize costs. The numerical results show that shocks at the reserve level have a significant effect on reserve management strategies and that model misspecification can result in nonnegligible additional costs.     

A GENERAL EQUILIBRIUM MODEL OF A MULTIFIRM MORAL‐HAZARD ECONOMY WITH FINANCIAL MARKETS

We present a general equilibrium model of a moral‐hazard economy with many firms and financial markets, where stocks and bonds are traded. Contrary to the principal‐agent literature, we argue that optimal contracting in an infinite economy is not about a tradeoff between risk sharing and incentives, but it is all about incentives. Even when the economy is finite, optimal contracts do not depend on principals’ risk aversion, but on market prices of risks. We also show that optimal contracting does not require relative performance evaluation, that the second best risk‐free interest rate is lower than that of the first best, and that the second‐best equity premium can be higher or lower than that of the first best. Moral hazard can contribute to the resolution of the risk‐free rate puzzle. Its potential to explain the equity premium puzzle is examined.     

A THREE‐STAGE IMPLEMENTATION MODEL FOR SUPPLY CHAIN COLLABORATION

Leading companies know that collaboration and creativity in supply chain (SC) relationships are critical to future competitiveness. Yet, many companies struggle to collaborate effectively. This reality raises the question: “How can managers overcome the cultural and structural impediments to SC collaboration?” Through a series of in-depth, semi-structured interviews, we identify core practices and key requirements to successful SC collaboration. Contingency and force field theories help transform our field study findings into a three-stage model for improving SC collaboration. The constant challenge of persuading other managers and companies to pursue SC collaboration highlights the need for a proven-path approach to SC collaboration.     

A STRUCTURAL RISK‐NEUTRAL MODEL FOR PRICING AND HEDGING POWER DERIVATIVES

We develop a structural risk‐neutral model for energy market modifying along several directions the approach introduced in Aïd et al. In particular, a scarcity function is introduced to allow important deviations of the spot price from the marginal fuel price, producing price spikes. We focus on pricing and hedging electricity derivatives. The hedging instruments are forward contracts on fuels and electricity. The presence of production capacities and electricity demand makes such a market incomplete. We follow a local risk minimization approach to price and hedge energy derivatives. Despite the richness of information included in the spot model, we obtain closed‐form formulae for futures prices and semiexplicit formulae for spread options and European options on electricity forward contracts. An analysis of the electricity price risk premium is provided showing the contribution of demand and capacity to the futures prices. We show that when far from delivery, electricity futures behave like a basket of futures on fuels.     

OPTIMAL LIQUIDATION IN A LIMIT ORDER BOOK FOR A RISK‐AVERSE INVESTOR

In a limit order book model with exponential resilience, general shape function, and an unaffected stock price following the Bachelier model, we consider the problem of optimal liquidation for an investor with constant absolute risk aversion. We show that the problem can be reduced to a two‐dimensional deterministic problem which involves no buy orders. We derive an explicit expression for the value function and the optimal liquidation strategy. The analysis is complicated by the fact that the intervention boundary, which determines the optimal liquidation strategy, is discontinuous if there are levels in the limit order book with relatively little market depth. Despite this complication, the equation for the intervention boundary is fairly simple. We show that the optimal liquidation strategy possesses the natural properties one would expect, and provide an explicit example for the case where the limit order book has a constant shape function.     

NO‐ARMAGEDDON MEASURE FOR ARBITRAGE‐FREE PRICING OF INDEX OPTIONS IN A CREDIT CRISIS

In this work, we consider three problems of the standard market approach to credit index options pricing: the definition of the index spread is not valid in general, the considered payoff leads to a pricing which is not always defined, and the candidate numeraire for defining a pricing measure is not strictly positive, which leads to a nonequivalent pricing measure. We give a solution to the three problems, based on modeling the flow of information through a suitable subfiltration. With this we consistently take into account the possibility of default of all names in the portfolio, that is neglected in the standard market approach. We show on market inputs that, while the pricing difference can be negligible in normal market conditions, it can become highly relevant in stressed market conditions, like the situation caused by the credit crunch.
