A systematic literature review to integrate lean,agile, resilient,green and sustainable paradigms in the supply chain management

The main focus of this study is to conduct a systematic literature review to integrate lean, agile, resilient, green and sustainable (LARGS) paradigms in the supply chain (SC) domain. To achieve this aim, several research questions were designed: First, how to locate LARGS research in context of SC domain? For this, it is important to understand which types of research articles should be selected for the study? Further, where such studies were conducted (geographical location)? Second, what is the focus of research in LARGS paradigm in SCs? For this, it is important to study, which types of industries or sectors have been targeted in literature? In addition, which tools and techniques have been used mostly? Third, what are the current trends in the relationships of LARGS paradigms, among themselves, and with SC performance measures? Fourth, what are the emerging issues, unexplored areas in this field, based on these what could be future research avenues in this subject domain have been proposed? A total of 160 relevant articles published during 1999–2019 were used for analysis. Based on analysis, findings are summarised, and main research issues and possible future research directions in LARGS paradigms in SCs are highlighted.     

The dynamics of volatility transmission and information flow between ADRs and their underlying stocks

This research examines the dynamics of volatility transmission and information flow between ADRs and the underlying stocks. Using a bivariate GARCH model with BEKK parameterisation, the study investigates how changes in volatility in the ADR market affect the volatility in the underlying equity market and vice versa. The findings suggest a bidirectional volatility transmission and information flow between the ADR and underlying stock markets. ADRs and underlying stocks respond to their own innovations as well as to the innovations in each other's market. The findings are consistent for all countries in the sample as well as for different sub-periods. The evidence suggests that the differences in synchronicity of trading period between the US market and other developed markets included in the sample has had no effect on the volatility transmission and information flow between ADRs and underlying stocks.     

Do managers know what their customers think and why?

The ability of a firm’s managers to understand how its customers view the firm’s offerings and the drivers of those customer perceptions is fundamental in determining the success of marketing efforts. We investigate the extent to which managers’ perceptions of the levels and drivers of their customers’ satisfaction and loyalty align with that of their actual customers (along with customers’ expectations, quality, value, and complaints). From 70,000 American Customer Satisfaction Index (ACSI) customer surveys and 1068 firm (manager) responses from the ACSI-measured companies, our analyses suggest that managers generally fail to understand their firms’ customers in two important ways. First, managers systematically overestimate the levels of customer satisfaction and attitudinal loyalty, as well as the levels of key antecedent constructs such as expectations and perceived value. Second, managers’ understanding of the drivers of their customers’ satisfaction and loyalty are disconnected from those of their actual customers. Among the most significant “disconnects,” managers underestimate the importance of customer perceptions of quality in driving their satisfaction and of satisfaction in driving customers’ loyalty and complaint behavior. Our results indicate that firms must do more to ensure that managers understand how their customers perceive the firm’s products and services and why.     

Decentralized capacity management and internal pricing

This paper studies the acquisition and subsequent utilization of production capacity in a multidivisional firm. In a setting where an upstream division provides capacity services for itself and a downstream division, our analysis explores whether the divisions should be structured as investment or profit centers. The choice of responsibility centers is naturally linked to the internal pricing rules for capacity services. As a benchmark, we establish the efficiency of an arrangement in which the upstream division is organized as an investment center, and capacity services to the downstream division are priced at full historical cost. Such responsibility center arrangements may, however, be vulnerable to dynamic hold-up problems whenever the divisional capacity assignments are fungible in the short-run, and therefore, it is essential to let divisional managers negotiate over their actual capacity assignments. The dynamic hold-up problem can be alleviated with more symmetric choice of responsibility centers. The firm can centralize ownership of capacity assets with the provision that both divisions rent capacity on a periodic basis from a central unit. An alternative and more decentralized solution is obtained by a system of bilateral capacity ownership in which both divisions become investment centers.     

Bill-and-Keep peering

Peering arrangements between Internet Service Providers (ISPs), in which providers agree to carry traffic originating from a peer, are common in the Internet. A common contractual peering agreement between smaller ISPs is “Bill-and-Keep”, where no money changes hands between the peers. This paper first investigates a situation when ISPs who have access to a transit ISP capable of handling their traffic for a fee, decide to peer incurring some fixed peering cost. Using a simple model it is shown that Bill-and-Keep peering is the fair and efficient outcome if the transit ISP charges for both inbound and outbound traffic and transit charges as well as costs of peering are symmetric. Next, complementarity between providers at the operational level, as measured by improvement in quality of service (QoS), is analyzed using an idealized model. Assuming that each provider incurs costs, or degradation in QoS, from its traffic traversing its own as well as the peer's links and chooses the amount of traffic to send on its peers’ links in its self-interest, the Nash equilibria of the resulting one shot game and then of an infinitely repeated game are analyzed. For the one-shot game, it is established that, while it is not possible for all the providers to be worse off, it is certainly possible for all of them to be better off. An intuitive sufficient condition for each of the providers to be better off in Nash equilibrium is then derived. Further, it is shown that providers that are better off in the one-shot game can cooperate using threat strategies in an infinitely repeated game and can each be even better off. Coalition formation between peers as a dynamic process is also investigated and some examples and conjectures on some preliminary findings are provided. Finally, the policy implications of the findings are discussed.     

The dynamics between stock returns and mutual fund flows: empirical evidence from the Greek market

This paper examines the interaction between mutual fund flows and stock returns in Greece. Specifically, we investigate the possibility of a causality mechanism through which mutual funds flows may affect stock returns and vice versa. The statistical evidence derived from the error correction model indicates that there is a bidirectional causality between mutual fund flows and stock returns. Cointegration results show that mutual funds flows cause stock returns to rise or fall. This may be explained by the fact that, in Greece, equity mutual funds are obliged by law to invest a certain percentage of their cash in stocks. Thus, inflows and outflows of cash in equity funds seem to cause higher and lower stock returns in Greek stock market.     

Preference aggregation and repeat buying in households

Marketing researchers have long used brand switching analyses and Markov transition matrices to gain insights into managerial problems. Almost without exception, this work makes (inappropriate) inferences about individual consumers by analyzing household-level data. This paper presents a procedure based on the distribution of run lengths in household level panel data that allows more insights into the choice behavior of the individuals in the household. We test these procedures in a large simulation study by attempting to recover the underlying (known) structure of the process generating a string of panel data. Finally, we use the procedure to classify the purchase behavior, with respect to powdered soft drinks, of a set of households in a panel. Our results show that marketing scientists have the potential to learn and test more hypotheses about the individuals in a household by examining the distribution of run lengths.We gratefully acknowledge Professor Bari Harlam of the University of Rhode Island for providing the panel data.     

The Effect of Earnings Forecasts on Earnings Management

We develop a theory of the association between earnings management and voluntary management forecasts in an agency setting. Earnings management is modeled as a "window dressing" action that can increase the firm's reported accounting earnings but has no impact on the firm's real cash flows. Earnings forecasts are modeled as the manager's communication of the firm's future cash flows. We show that it is easier to prevent the manager from managing earnings if he is asked to forecast earnings. We also show that earnings management is more likely to follow high earnings forecasts than low earnings forecasts. Finally, our analysis shows that shareholders may not find it optimal to prohibit earnings management. Earlier results rationalize earnings management by violating some assumption underlying the Revelation Principle. By contrast, in our model the principal can make full commitments and communication is unrestricted. Nonetheless, earnings management can be beneficial as it reduces the cost of eliciting truthful forecasts.
