An inventory reservation problem with nesting and fill rate-based performance measures

In many inventory settings companies wish to provide customer-differentiated service levels. These may, for example, be motivated by differences in the perceived customer lifetime value or by specific contractual agreements. One approach to provide differentiated service levels is to reserve some portion of the available inventory exclusively for specific customer classes. Existing approaches to inventory reservation are typically based on the assumption that a company can assign a customer specific revenue or penalty cost to any order or unit of demand filled or unfulfilled. In practice, however, it is usually extremely difficult to accurately estimate (especially long term) monetary implications of meeting or not meeting customer demand and corresponding service level requirements. The research presented in this paper addresses the problem of setting appropriate inventory reservations for different customer classes based on fill rate-based performance measures. We model a single period inventory reservation problem with two customer classes and nesting. We develop exact expressions for two conflicting performance measures: (1) the expected fill rate of high priority customers and (2) the expected loss in the system fill rate induced by inventory reservation. With these expressions a decision maker can analyze the tradeoff between the loss in overall system performance and the higher expected fill rates for prioritized customers. We provide analytical insights into the effects of nesting and the impact of relevant problem parameters on these two performance measures. The analytical insights are illustrated and highlighted through a set of numerical examples. Although we limit our analysis to a single period inventory reservation problem, we expect that our results can be utilized in a wide range of problem settings in which a decision maker has to ration a perishable resource among different classes of customers.     

Cost Accounting and Performance Measurement in a Just-in-Time Production Environment

There are normative statements in the literature, backed up by case observations and anecdotal evidence, which indicate that manufacturing companies operating just-in-time (JIT) production management systems should also change their cost accounting systems and place greater reliance on non-financial performance indicators. This study provides empirical evidence suggesting that JIT manufacturing companies which have made some degree of modification to their costing system demonstrate higher performance than JIT companies which have not made changes. The results also suggest that greater use of non-financial performance indicators is associated with higher performance irrespective of the production management system adopted.     

Trust-opportunism paradox,relationalism, and performance in interfirm relationships: evidence from the retail industry

Building on recent theoretical work documenting that interorganizational relationships (IORs) are ‘multifaceted and multiplex’ we investigate, from the agent's perspective, the joint effects of trust and opportunism in fostering (or inhibiting) relationalism, which, in turn, is predicted to influence performance within interfirm exchange relationships. Based on longitudinal survey data on 409 catalog intermediaries affiliated with a large retail firm, we found strong support for most of the hypothesized relationships. Implications for future research are offered. Copyright © 2008 John Wiley & Sons, Ltd.     

Protectionism indices for non-tariff measures: An application to maximum residue levels

We propose aggregation indices of Non-Tariff Measures (NTMs) to quantify their protectionism relative to international standards of stringency. We apply the indices to national Maximum Residue Limit (MRL) regulations on pesticides and veterinary drugs affecting agricultural and food trade and using a science-based criteria embodied in Codex Alimentarius international standards. The approach links two streams of the NTM literature, one concerned with the aggregation of various NTMs into operational indices for econometric and modeling purposes, and the other attempting to evaluate the protectionism of NTMs. The data used in the application come from a large international dataset on veterinary and pesticide MRLs and CODEX MRL standards for a large set of countries.     

Measures of Joint Venture Performance from Multiple Perspectives: An Evaluation by Local and Foreign Managers in Vietnam

A study was undertaken to identify the most relevant performance evaluation measures for joint venture managers and to analyze differences in perception about joint venture performance between foreign and Vietnamese joint venture managers. The results revealed five factors belonging to three perspectives of particular relevance to managers: operational efficiency (economic indicator), competitiveness and external customer relations (strategic indicators) as well as equity and working relationship (behavioral indicators). This study also points out that under normal operating conditions, there are no significant differences in perception between foreign and Vietnamese joint venture managers regarding both efficiency and equity. This confirms the need for equity in a joint venture relationship in order to maintain balance between the partners and avoid dissolution.

"一股独大"悖论:中国证券市场的经验证据

目前对于中国证券市场诸多问题的探讨大多集中于“一股独大”，似乎其是“万恶之源”。本文采用主成分分析和多元回归的统计方法，系统分析了股权集中程度、第一大股东性质与综合业绩的相关关系。本文发现：股权集中度与综合业绩存在正相关关系，第一大股东为国有行政性单位的上市公司较第一大股东为非行政性单位的上市公司的综合业绩要差。鉴于本文的经验证据与现行主流观点相左，所以有“悖论”之称。针对这一“悖论”，本文给出了两个解释。     

The risk‐return paradox for strategic management: disentangling true and spurious effects

The concept of risk is central to strategy research and practice. Yet, the expected positive association between risk and return, familiar from financial markets, is elusive. Measuring risk as the variance of a series of accounting‐based returns, Bowman obtained the puzzling result of a negative association between risk and mean return. This finding, known as the Bowman paradox, has spawned a remarkable number of publications, and various explanations have been suggested. The present study contributes to this literature by showing that skewness of individual firm' return distributions has a considerable spurious effect on the empirically estimated mean‐variance relationship. I devise a method to disentangle true and spurious effects, illustrate it using simulations, and apply it to empirical data. It turns out that the size of the spurious effect is such that, on average, it explains the larger part of the observed negative relationship. My results might thus help to reconcile mean‐variance approaches to risk‐return analysis with other, ex‐ante, approaches. In concluding, I show that the analysis of skewness is linked to all three streams of literature devoted to explaining the Bowman paradox. Copyright © 2008 John Wiley & Sons, Ltd.     

An analysis of B2B ingredient co-branding relationships

The proliferation of co-branding in consumer markets has been given considerable attention in the literature, yet attention to the practice in business-to-business markets has been limited, despite the growing attention to the role of relationships in the B2B arena. In an examination of co-branding in the industrial sector, this paper discusses the use of ingredient co-branding and uses an econometric modeling approach to offer a rationale for why it occurs. The analysis provides insight into why downstream manufacturers participate in a relationship that strengthens the supplier's position in the market. We find that under the threat to the supplier of entry from a competitor whose costs are unobservable, co-branding relationships will be entered into resulting in a reduced probability of entry. This co-branding arrangement benefits both the incumbent supplier and the downstream manufacturer. The incumbent supplier benefits from the reduced probability of competitor entry, and the downstream manufacturer is rewarded with a lower price. Further, we find that the cost of the co-branded product is lower, due to a mitigation of double marginalization in a vertically-integrated solution. We examine co-branding relationships with and without advertising support and find that co-branding relationships with advertising support tend to be superior.

An analysis of international business-to-business relationships based on the Commitment-Trust theory

Business-to-business relationships are characterized by an exchange between two or more parties. Research has identified several factors that enhance marketing and management in business relationships, mainly with a focus on large manufacturing firms. However, less is known about how service firms develop and maintain international relations during the establishment of a business. To analyze the relevance of the key mediating variable (KMV) model [J. Mark. 58 (1994) 20-38.], which maintains that business-to-business relationship requires commitment and trust, interviews were conducted with five different service entrepreneurs in Sweden, Australia and the UK. The findings demonstrate the importance of commitment, trust, relation termination costs and benefits, shared values and communication between the exchange partners.     

Alternative profitability measures and tests of the structure-performance relationship

This paper compares the inferences gained when alternatively specifying Census-based price-cost margin and IRS-based accounting rate of return as the dependent variable in conventional structure-performance models. We find important differences between the structure-performance inferences of the alternative specifications of the profit measure. Further, the alternative profit measures are not highly correlated.The authors acknowledge the constructive comments of an anonymous referee.     

Construct validity of some unweighted product-count diversification measures

Construct validities are assessed for three simple-to-compute, unweighted, SIC-based continuous diversification measures and a recently proposed two-dimensional, SIC-based categorical diversification measure. Two of the three continuous measures are found to correspond strongly to Rumelt's categorical measures, suggesting that these two objective and easy-to-calculate measures are better suited for large sample, strategy research than has previously been assumed. No support is found for the two-dimensional measure.     

Sales force automation systems: An analysis of factors underpinning the sophistication of deployed systems in the UK financial services industry

This study investigates organizational and strategic context variables that are linked to the sophistication of sales force automation systems in UK financial services firms. We find that increasing sophistication in SFA deployment, evaluated as a count of the number of types of results of sales campaigns that are measured, is driven directly by the information orientation of the host firm. We also find that the “sophistication” of deployed systems is, in fact, limited — the information held on the systems cannot underpin the strategic goals of the sales/marketing managers. We theorise that adoption of SFA systems is driven by managerial imperatives and that these have resulted in sales force resistance — shown by the paucity of information held on adopted SFA systems.     

Industrial tail exposure risk and asset price: Evidence from US REITs

In this study, we investigate the impact of industry-based tail dependence risk on the cross-section of stock returns. To this end, we propose a novel tail risk dependence measure (industrial tail exposure risk [ITER]), which captures the tail risk exposure of individual stocks to multiple industries. Using US equity real estate investment trusts (REITs) data from 1993 to 2020, we document that stocks in the highest ITER portfolio outperform stocks in the lowest ITER portfolio by 8.40% per annum. This positive return spread is significant even after controlling for well-known firm characteristics. The return premium of ITER is stronger for small, value, and highly levered stocks and is substantially high during recession periods. Finally, the effects of ITER are cross-sectionally more associated with REITs that have greater degrees of the following factors: bivariate tail exposure risks of major industries, exposure to local industry tail risk, geographical concentration, and ownership of home-biased investors. Overall, our results suggest that REIT investors are indeed averse to tail risks that are associated with various sectors.     

The impacts of marketing and operations capabilities on financial performance in the UK retail sector: A resource-based perspective

Drawing upon the resource-based view (RBV) of the firm, this study investigates the relationships among marketing capability, operations capability, and financial performance. Using archival data of 186 retail firms in the UK, we find that that marketing capability has a significant impact on operations capability, and that operations capability is significantly and positively related to retail efficiency. The results also suggest that operations capability fully mediates the relationship between marketing capability and financial performance. The findings of this study provide practical insights for practicing managers to consider when developing functional capabilities in order to achieve superior financial performance.     

Key account relationships: An exploratory inquiry of customer-based evaluations

The management and retention of key accounts is imperative in facilitating a firm's long-term viability. Previous examinations of key account relationships have revealed valuable insights into the factors facilitating key account management and driving relationship strength. However, account managers often fail to recognize weaknesses within their existing key accounts and the sources of their relationship vulnerabilities. Utilizing an exploratory inquiry of in-depth interviews with 99 executive decision makers across 52 key accounts cases, the authors assess customer relationship evaluations prior to contract expirations for account retention opportunities valued at over $1.3 billion. Unique positive and negative drivers of key account relationship evaluations are identified in a thematic categorization, along with a subsequent content analysis highlighting their patterned associations with positive and negative relationship evaluations, future business intentions, and business referral behaviors. These patterned associations reveal that positive and negative perceptions of relational drivers often affect outcomes in a differential manner, resulting in a classification of conventional constructs, prevention constructs, and promotion constructs. The results indicate that the desire of a supplier to maximize positive relational outcomes or minimize negative relational outcomes is driven by distinct underlying associations and allow for insights into resource allocation strategies within key account relationships.
