Stock replenishment policies for a vendor-managed inventory in a retailing system

Using Vendor Managed Inventory (VMI), the vendor determines the replenishment decisions at the location of buyers (retailers). This strategy is used primarily for handling demand fluctuations stemming from the Bullwhip effect, leading the system to prevent from holding excessive inventory that result in a reduction in the overall cost of the supply chain. The main advantages of VMI for vendors are higher levels of accessibility to inventory information and more direct contact with the customers. Similarly, VMI has some pros for the buyers, such as shared risk with upper levels of supply chain and reduction in their holding costs of inventory. In this paper, a vendor-managed inventory system is developed containing one vendor and two buyers in which the main assumption is that back-ordering and lost sales are permitted. In this system, (r, Q) and (R, T) replenishment policies are compared according to their performances to see which one performs more cost-efficiently when partial back-ordering is allowed. In accordance, mathematical models utilizing (r, Q) and (R, T) replenishment policies are developed, and algorithms for deriving the optimal replenishment decision variables are proposed. Moreover, significant differences between the two replenishment policies are discussed. The main finding obtained by this research is that when shortage is permitted, both (r, Q) and (R, T) replenishment policies under VMI have pros and cons in different contexts.     

Enhancing bank performance through branches or representative offices? Evidence from European banks

We investigate the impact of geographic integration and the level of multinationality by expansion as a foreign branch or representative office on the parent bank performance of 45 European banks during 2000–2007. We use breadth and depth to proxy for the level of multinationality in measuring a parent bank performance. We find that for foreign expansion as a branch, both dimensions (breadth and depth) have a positive impact on a bank's return on assets (ROA). For return on equity (ROE) and Tobin's Q, only depth is positively associated with a bank's ROE while breadth is positively correlated with a bank's Tobin's Q. However, the impact from expansion as a representative office is different; breadth and depth only have a positive impact on bank ROA performance in one of the six models. In terms of cost control, a representative office strategy is better able to control costs than a branching strategy. The model goodness of fit statistics suggest that variables associated with branching better explain the performance variables than similar variables associated with representative offices in terms of profitability. The results are opposite for net interest margin and cost ratio. Overall, our findings suggest that a branching strategy is a more effective strategy in enhancing a bank's profitability while a representative office strategy controls costs better.     

Do Investors Value a Firm’s Commitment to Social Activities?

Previous empirical research has found mixed results for the impact of corporate social responsibility (CSR) investments on corporate financial performance (CFP). This paper contributes to the literature by exploring in a two stage investor decision-making model the relationship between a firm’s innovation effort, CSR, and financial performance. We simultaneously examine the impact of CSR on both accounting-based (financial health) and market-based (Tobin’s Q) financial performance measures. From a sample of top corporate citizens, we find that: (1) a firm’s social responsibility commitment (CSR) contributes to its financial performance; (2) after controlling for investment in innovation activities, CSR continues to have a positive impact on a firm’s financial performance; (3) the customer dimension of CSR has a positive effect on both CFP measures, whereas the employee dimension indicates a significant impact only on financial heath; and (4) the community relation dimension of CSR only affects the market-based CFP measure of firms with high innovation intensity.     

The Agency Problems Embedded in Firm’s Equity Investment

We find that agency problems are embedded in firm’s excess and abnormal equity investments that are mainly dictated by controlling shareholder’s motives and ethical choices manifested in ownership and board structure. The excess equity investment is gauged with respect to industry average. The abnormal equity investment is specifically referred to the number of nominal investment companies that are fully controlled by the controlling owners while subject to little governance. Our empirical evidences of 345 Taiwanese non-financial listed firms show that firm’s excess and abnormal equity investments are negatively correlated with controlling shareholder’s cash flow rights while are positively correlated with the control–cash flow deviation, and board affiliation. The results are supportive of the positive incentive hypothesis and the negative entrenchment hypothesis put forth by La Porta et al. (2002, Journal of Finance 57, 1147–1171) and Claessen et al. (2002, Journal of Finance 57, 2741–2742). The negative relation between equity investment and firm’s value further supports the agency postulation that corporate excess and abnormal equity investments represent a leeway for controlling shareholder to exploit wealth of minority shareholders. This study potentially contributes to the literature of business ethics by portraying an empirically testable linkage from controlling owner’s ethical choices to his actions and therefore firm’s value.

Mean–variance hedging of contingent claims with random maturity

We study the mean–variance hedging of an American-type contingent claim that is exercised at a random time in a Markovian setting. This problem is motivated by applications in the areas of employee stock option valuation, credit risk, or equity-linked life insurance policies with an underlying risky asset value guarantee. Our analysis is based on dynamic programming and uses PDE techniques. In particular, we prove that the complete solution to the problem can be expressed in terms of the solution to a system of one quasi-linear parabolic PDE and two linear parabolic PDEs. Using a suitable iterative scheme involving linear parabolic PDEs and Schauder's interior estimates for parabolic PDEs, we show that each of these PDEs has a classical C^{1, 2} solution. Using these results, we express the claim's mean–variance hedging value that we derive as its expected discounted payoff with respect to an equivalent martingale measure that does not coincide with the minimal martingale measure, which, in the context that we consider, identifies with the minimum entropy martingale measure as well as the variance-optimal martingale measure. Furthermore, we present a numerical study that illustrates aspects of our theoretical results.     

Enhancing market discipline in banking: The role of subordinated debt in financial regulatory reform

The increasing complexity of large financial firms has led to consideration of alternative regulatory structures. This has intensified recently because of the worldwide turmoil in financial markets. One important consideration has been to increase reliance on market discipline—most notably, increased reliance on subordinated debt (sub-debt) in the bank capital structure to discipline banks’ risk taking. This proposal, however, has been subject to criticism related to the quality of the signal generated in current sub-debt markets. We argue that previous studies evaluating the potential usefulness of sub-debt proposals have evaluated sub-debt spreads in a very different environment from that characterized by a fully implemented sub-debt program, where the market will become deeper, issuance will be more frequent, debt will be viewed as a more viable means to raise capital, bond dealers will be less reluctant to publicly disclose more details on debt transactions, and generally, the market will be more closely followed. As a test to see how the quality of the signal may change, we evaluate the risk-spread relationship—accounting for the enhanced liquidity and market transparency surrounding new debt issues. Our empirical results indicate a superior risk-spread relationship surrounding the period of new debt issuance due, we posit, to greater liquidity and transparency. Our results overall suggest that the degree of market discipline would be significantly enhanced by a mandatory sub-debt program, thus suggesting a potential role for sub-debt in the banking regulatory reform.     

Do consumer perceptions matter in measuring choice variety and variety seeking?

This research marries scanner panel choice data of consumers in single member households to their survey-based perception data and draws upon behavioral and modeling research to contribute to the variety seeking literature. It presents a new consumer-based measure of choice variety based on inter-product similarity perceptions and illustrates that others-based (i.e., researchers, managers, and retailers) measures of choice variety such as number of brand switches underestimate choice variety. Moreover, incorporating the consumer-based measure instead of others-based measures in latent class models improves their efficiency of classifying households into high versus low variety seeking. The consumer-based measure of choice variety is valid in terms of its positive relationship with consumer's intrinsic or trait-based variety seeking tendency. Theoretical (market structure, consideration set) and managerial implications (targeting of price promotions to reduce spending, product design, cross-price elasticity) of the findings are offered.     

Measuring the value of mobile telecommunications networks

Fuentelsaz, Garrido and Maicas (2015) propose an “improved” measure of network value for the mobile telecommunications industry. Unfortunately, their measure has multiple issues. For one, it is biased against networks that are small and/or active in small markets. Also, it cannot adequately take into account intertemporal changes in mobile operators’ price discrimination behaviour. Finally, where the functional form of the network effects is concerned, Fuentelsaz et al. invoke Zipf’s law without providing any empirical justification. This paper suggests an alternative for Fuentelsaz et al.’s measure and exploits as yet unused data on on-net discounts to apply it to the cases of Germany and Belgium. It is shown that the alternative measure does not suffer from the same weaknesses as Fuentelsaz et al.’s measure – bar the final one. The paper therefore screens the literature on other network industries in search of an empirical foundation for the network externality assumption. However, the paper finds that the broader literature is also still struggling with this issue.     

Inside the regional multinationals: A new value chain perspective on subsidiary capabilities

We discuss the strategic significance of ‘regional multinationals’, and highlight a number of conceptual and empirical challenges that a regional multinationals research agenda should address. In line with the intellectual legacy of the late Alan Rugman, we argue that to deepen our understanding of regional strategy and organization, we cannot limit ourselves to studying the multinational enterprise’s (MNE’s) geographic footprint, but we must also explore the entire spectrum of regional elements in the firm’s organizational functioning, including the impact of the regional effect on subsidiary capabilities across the value chain. More specifically, we argue that operating in a host region can affect a foreign subsidiary’s capabilities: subsidiaries of outsider MNEs (meaning headquartered outside of the region) are disadvantaged as compared to insider MNE subsidiaries. This regional effect, however, is predicted to vary according to the value chain activity considered. Further, the regional effect will tend to diminish over time, though at a different pace for the various value chain activities.     

Disclosure of Downside Risk and Investors' Use of Qualitative Information: Evidence from the IPO Prospectus's Risk Factor Section

I use the context of a company's initial public offering (IPO) of equity securities as a capital‐market setting to empirically study the economic consequences of risk factor disclosures. Using data from Australian IPOs, I examine the relation of textual risk disclosures in the prospectus to initial underpricing. I find that the quantity of disclosures in the risk factor section itself has no significant impact on initial underpricing. However, an increase in the informativeness of risk factor disclosures is associated with lower IPO underpricing. My results suggest that IPOs that provide informative risk factor disclosures have less ex ante uncertainty, in the sense that the disclosures help investors estimate the dispersion of secondary market value. The effect of informative risk factor disclosures on IPO underpricing is more pronounced for IPOs with less prestigious lead underwriters and is mainly driven by younger firms, smaller firms, and firms with poorer operating performance prior to their IPOs. Collectively, my findings suggest that informative disclosures of downside risk are useful for investors to evaluate IPOs.     

The role of customer gratitude in making relationship marketing investments successful

This paper recognises that customer loyalty is important for many competitive organisations, and that retail firms make investments to build and maintain loyal relationships with their existing and potential customers (e.g. loyalty programs). However, there has been little focus on the mechanisms by which these relationship investments operate to achieve customer loyalty. This paper examines one mechanism, namely customer gratitude, which works to make a firm’s relationship marketing investment a success or a failure. Using data from 1600 undergraduate students, this study empirically confirms the mediating role of customer gratitude between the customers’ perceptions a firm’s relationship marketing investments and customers’ perceptions of the value of the relationship with the firm. Further, a significant moderating effect of perceived benevolence on the relationship between customers’ perceptions a firm’s relationship marketing investments and customer gratitude was identified. For theorists, this customer gratitude model offers a better psychological explanation of how relationship marketing investments operate to improve the value that customers place on their relationships with retailers. Our research suggests that managers should invest resources to stimulate customer gratitude in order to build strong customer–seller relationships.     

Hofstede's individual-level indulgence dimension: Scale development and validation

In spite of the important role of culture in consumer behavior, there has been no study of the effects of indulgence vs. restraint, the sixth dimension of Hofstede's cultural framework, at the individual level. This is mainly because there has been no scale to measure indulgence vs. restraint at the individual level. Given that ascribing national-level cultural scores to individuals may cause an ecological fallacy, the four studies of this research conceptualize and develop a valid and reliable measure for individual-level indulgence. In study 1 (n= 290), using PCA, the items were purified to the final six items. The result of an EFA in study 2 (n=230) suggested a unidimensional six-item structure for the scale. This structure was confirmed by a CFA in study 3 (n=257). Study 3 established the reliability, convergent, discriminant, and criterion validities of the scale. In study 4 (n=219), through developing and testing the nomological network, the nomological validity of the scale was supported by showing that the impacts of individual-level indulgence on hedonic attitudes and repurchase intentions are mediated by positive post-purchase emotions and hedonic attitudes, respectively.     

Cross-border marketing ecosystem orchestration: A conceptualization of its determinants and boundary conditions

The authors propose that the current trends and developments in the international marketplace call for a new theoretical concept-based approach to inform and guide cross-border marketing strategy. Specifically, the authors label this approach marketing ecosystem orchestration (MEO). The marketing ecosystem is defined as connected, interdependent, and co-evolving sets of actors, activities, and institutions enabling the marketing of an offering that has value for customers, clients, partners, and society at large. MEO is a new strategic approach for an internationalizing firm to achieve sustained value creation, value appropriation, and growth in a host market. Orchestration involves developing and/or coordinating the ecosystem’s interdependent – but independent actors, resources, information, processes, and services to create, co-create, and appropriate value from firms’ market-based assets. The authors theorize three components of MEO – the orchestration of supply chains and fulfillment networks, marketing communications, and transactions and payments sub-ecosystems – and develop a conceptual framework and propositions influencing the determinants of MEO adoption by the focal firm. This paper concludes with managerial implications and offers several new directions for international marketing research.     

A replication study of the credit card effect on spending behavior and an extension to mobile payments

Prior research has shown that credit cards increase spending behavior as measured by the willingness to pay (WTP) or basket value. This research aims to replicate the credit card effect and to extend this effect to mobile payments. In four empirical studies, of which three online studies and one lab study (total n = 692), we manipulated payment methods (i.e., cash, credit cards, and mobile payments) and measured spending behavior (i.e., WTP and basket value). Across four studies, we did not replicate the credit card effect on either measure of spending behavior, suggesting the effect in the literature may be inflated or may have been fading away. A meta-analysis of the relevant literature revealed the expected credit card effect but also showed that the credit card effect has become weaker through the years and that this effect is contingent on the location of data collection. We also did not find evidence that the credit card effect extends to mobile payments on either measure of spending behavior in the three online studies. However, we found a significant difference between mobile payments and cash on the basket value measure (but not for the WTP measure) in the lab study. This paper also explored whether the pain of payment or payment convenience may be a mechanism underlying the relationship between payment methods and spending behavior. Although the pain of payment tended to be lower and the payment convenience tended to be higher for mobile payments, these effects did not translate into more spending behaviors.     

Growing market concentration and changes in consumer welfare: The case of the U.S. commercial airline market

Initial assessments of the economic deregulation of the U.S. airline industry indicated that most consumers gained from the increased competition in the airline market. More recent studies have reached less favorable conclusions. In this study, changes in passenger welfare are determined for 19 U.S. destination cities for the years 1979, 1983, and 1987 on the basis of Hicks' equivalent variation measure, using a counterfactual research design. Particular attention is given to variations in consumer welfare gains/losses depending on (a) the proportion of the change in air fares attributed to deregulation, and (b) the destination airport's classification. The estimates suggest that travelers to large, long-standing hub cities were generally insulated from any large post-1979 welfare changes. Travelers to new hubs experienced substantial welfare declines between 1979 and 1987 — although their post-1983 welfare changes were uniformly positive. Travel to nonhub airports showed the greatest variance, with both the relatively largest welfare gains and the relatively largest losses.

World market integration through the lens of foreign direct investors

This paper is motivated by the unparalleled increase in foreign direct investment to emerging market economies of the last 25 years. Using a large cross-country time-series data set, we evaluate the dependence of foreign direct investment on global factors, or worldwide sources of risk (i.e., factors that drive foreign direct investment across several countries). We construct a globalization measure that equals the share of explained variation in direct investment attributable to global factors. We show that our globalization measure has increased steadily for developing and developed countries. For the full sample of countries, the globalization measure rose by over 10-fold from 1985 to 1999. Furthermore, in recent years, developing countries' exposure to global factors has approached that of developed countries. Finally, our globalization measure correlates strongly with measures of capital market liberalization, supporting our hypothesis that increased market integration leads to a greater role for worldwide sources of risk. We discuss the implications of our results for public policies regarding capital market liberalization and policies directed at attracting foreign investment.

Shopping motives,store attributes and shopping enjoyment among Malaysian youth

Youth shoppers are an emerging age group that is recognized as a meaningful market segment, yet there is lack of extant shopping enjoyment research explicit to the cohort especially in Malaysia context. This study endeavors to measure shoppers' shopping enjoyment and to explore the effect of both internal and external factors in influencing their shopping enjoyment levels. Shopping motives as the internal contributor is personal-specific while store attributes serve as the external aspect is regarded as situational-specific. By employing hierarchical multiple regression analysis, it was found that anticipated utility dimension from shopping motive variable and enhancement dimension from store attribute variable explained the variance in shopping enjoyment. Narrowing to the two variables identified, anticipated utility (β=0.198) from shopping motives was having more influential power than enhancement derived from store attributes (β=0.163) in explaining shopping enjoyment. The findings assist retailers in enhancing the perceived value of customers.     

The Roles of Cultural Elements in International Retailing of Cultural Products: An Application to the Motion Picture Industry

We investigate factors influencing the international retailing of cultural products by concentrating on two cultural elements: (1) consumer-perceived cultural content embedded in the product and (2) the general cultural environment of the foreign market. To test cross-culture predictability in international retailing, we develop a novel text mining procedure to elicit the specific cultural content of the product using consumers’ online product reviews. In addition, to measure the general cultural environment of the market, we apply Hofstede's cultural distance measure. To explain foreign markets’ acceptance of culturally specific elements, we theorize that the relationship between inter-country cultural distance and product sales is U shaped because of both cultural discount and cultural premium. In our empirical analysis using American movies in international retailing, we find that the two specified types of cultural factors determine a movie's success, along with the movie's characteristics and the market's economic environment. From a managerial perspective, international retailers that understand the delicate implications of the match/mismatch of their general national culture and the imported product's specific cultural content can better predict the international success of imported cultural products.
