Market research with the aid of a smartphone application – a case study

We discuss using the presumed ‘wisdom of the crowd’ to reduce the bullwhip effect in supply chains by enhancing the accuracy of demand forecast. Our case study describes a joint project of a leading European technology company (We chose RAGD as a pseudonym for the company throughout the study.) and the University of Kassel on a smartphone application for end customers to gather early information for this producer’s forecast. Our results confirm the ‘wisdom of the crowd’ hypothesis: A group of experts, in our case technicians who install and maintain RAGD-products, is capable of anticipating market fluctuations six weeks in advance. This only holds true if the ‘crowd’ of technicians is large enough. Our business climate index outperforms the company forecast in the first six months, when on average 22 technicians took part per week. We discuss successes and limitations of the cooperation and provide recommendations for similar projects.     

Does a Store Brand Always Hurt the Manufacturer of a Competing National Brand?

It is generally believed that store brands hurt the manufacturers of competing national brands while benefiting retailers. In this study, we challenge this notion by studying the impacts of a store brand when it is introduced by a power retailer. We show that a store brand may benefit the manufacturer when the interaction between the manufacturer and retailer is modeled as a retailer‐led Stackelberg game. This phenomenon occurs because the store brand changes the nature of the strategic interaction between the manufacturer and retailer in our model. In particular, while the interaction is always vertical strategic substitutability without a store brand, it may become vertical strategic independence with one. With the store brand, the demand for the national brand becomes larger, and the wholesale price for the national brand may increase, both of which benefit the manufacturer. Finally, the store brand may lessen the double marginalization problem of the supply chain for the national brand in the retailer‐led Stackelberg game, but does so in an unconventional way: The reduction in the double marginalization effect may come from a lowered retail markup instead of a lowered wholesale price. Our results reconcile some discrepancies between theoretical predictions and empirical findings regarding the impacts of store brands on manufacturers.     

Situation-based measurement of the full range of leadership model — Development and validation of a situational judgment test

In response to calls for context-specificity in leadership research, we developed and validated a Situational Judgment Test of the Full Range of Leadership Model (SJT-FRLM). Three consecutive studies were conducted following the typical steps of test development. Study 1 served measure development and pilot testing: item stems were generated empirically, item responses were developed with a theory-driven approach, and pilot testing was based on a leader sample. Study 2 served to analyze construct- and criterion-related validity of the instrument. Moreover, an empirical scoring key was developed that weights each item response according to its relation with leadership effectiveness in each situation. In Study 3, we demonstrated incremental validity and interrater agreement. The test fills an important gap in literature because it not only has predictive validity above and beyond established measures, but also takes into account the contextual element of leadership.     

Nordhaus–Gaddum type result for the matching number of a graph

For a graph G, \(\alpha '(G)\) is the matching number of G. Let \(k\ge 2\) be an integer, \(K_{n}\) be the complete graph of order n. Assume that \(G_{1}, G_{2}, \ldots , G_{k}\) is a k-decomposition of \(K_{n}\). In this paper, we show that (1)

$$\begin{aligned} \left\lfloor \frac{n}{2}\right\rfloor \le \sum _{i=1}^{k} \alpha '(G_{i})\le k\left\lfloor \frac{n}{2}\right\rfloor . \end{aligned}$$

(2) If each \(G_{i}\) is non-empty for \(i = 1, \ldots , k\), then for \(n\ge 6k\),

$$\begin{aligned} \sum _{i=1}^{k} \alpha '(G_{i})\ge \left\lfloor \frac{n+k-1}{2}\right\rfloor . \end{aligned}$$

(3) If \(G_{i}\) has no isolated vertices for \(i = 1, \ldots , k\), then for \(n\ge 8k\),

$$\begin{aligned} \sum _{i=1}^{k} \alpha '(G_{i})\ge \left\lfloor \frac{n}{2}\right\rfloor +k. \end{aligned}$$

The bounds in (1), (2) and (3) are sharp. (4) When \(k= 2\), we characterize all the extremal graphs which attain the lower bounds in (1), (2) and (3), respectively.

     

Does shareholder protection affect the performance of analysts as a gatekeeper?

This paper investigates the effect of shareholder protection on analysts’ performance. The important corporate governance role analysts can play by monitoring management has largely been ignored in the literature. Using a newly constructed index, we are for the first time able to analyse how changes in shareholder protection over time affect analysts’ performance as a gatekeeper. We find that strengthened shareholder protection improves analysts’ performance as a gatekeeper, i.e. analysts’ ability to reduce information asymmetry improves with strengthened shareholder protection. However, we also find a substitution effect: Strengthened shareholder protection makes analysts’ services less valuable to investors, thereby leading to a reduction in the number of analysts following firms.     

‘Training,it's a load of crap!’: the story of the hairdresser and his ‘Suit’

Many managers of small and medium-sized enterprises (SMEs) are more concerned about survival rather than growth. There are consistent findings that indicate managers in SMEs do not respond favourably to offers of HRD interventions and government policy now recognizes the value of informal learning and demand-led intervention. A social constructionist approach is suggested to consider engaging and working with SME managers. A framework of SME ‘worlds’ is considered before the case of one SME is examined. Using data from three different sources, the various positionings are considered. The case shows how from an apparently antagonistic view of external training, the manager was prepared to allow a coach/mentor to work with him towards his vision for expansion and growth. Conclusions are provided concerning engagement and stretch with SMEs, policy and future funding for HRD and the definition of skills development.     

Delistings and the costs of governance: a study of European stock exchanges 1996–2004

In recent years there has been a dramatic increase in delistings from stock exchanges in the US and Europe, and this trend has been partly attributed to increasing administrative costs in listed companies. Has corporate governance regulation gone too far? We examine delistings from European stock exchanges 1996–2004 and find that standard corporate governance regulation—like investor protection and corporate governance codes—is associated with more delistings and in particularly going private transactions. In contrast, the tendency to go private is found to be lower, when the quality of overall governance is high. The results continue to hold when we take into consideration that governance policy may be endogenous.     

An extension of the relaxation algorithm for solving a special case of capacitated arc routing problems

In this paper, we propose an exact method for solving a special integer program associated with the classical capacitated arc routing problems (CARPs) called split demand arc routing problems (SDARP). This method is developed in the context of monotropic programming theory and bases a promising foundation for developing specialized algorithms in order to solve general integer programming problems. In particular, the proposed algorithm generalizes the relaxation algorithm developed by Tseng and Bertsekas (Math. Oper. Res. 12(4):569–596, 1987) for solving linear programming problems. This method can also be viewed as an alternative for the subgradient method for solving Lagrangian relaxed problems. Computational experiments show its high potential in terms of efficiency and goodness of solutions on standard test problems.     

Bounding the total domination subdivision number of a graph in terms of its order

The total domination subdivision number \(\mathrm{sd}_{\gamma _{t}}(G)\) of a graph G is the minimum number of edges that must be subdivided (each edge in G can be subdivided at most once) in order to increase the total domination number. In this paper we prove that \(\mathrm{sd}_{\gamma_{t}}(G)\leq \lfloor\frac{2n}{3}\rfloor\) for any simple connected graph G of order n≥3 other than K ₄. We also determine all simple connected graphs G with \(\mathrm{sd}_{\gamma_{t}}(G)=\lfloor\frac{2n}{3}\rfloor\).     

Do exits proxy a liability of foreignness?: The case of Japanese exits from the US

Progress in understanding the liability of foreignness requires accurate measurement of this concept. This paper investigates whether exits of foreign affiliates from a given host market provide a reliable measure. We tackle this question by investigating 32 exits of Japanese manufacturing affiliates from the US. Our goal is to assess the extent to which exits are driven by a liability of foreignness and thus whether exits can serve as a reliable measurement of this liability. We find that less than half of our exits are attributable to a liability of foreignness. We conclude that while the data confirm a liability of foreignness for Japanese early entrants into the US, the presence of many other motives for exit suggests caution when inferring such a liability from exits, especially when exit costs are low.     

Detrimental Effects of Performance-Related Pay in the Public Sector? On the Need for a Broader Theoretical Perspective

Performance-related pay has been a key ingredient in New Public Management reforms. Nevertheless, the research presented here indicates some adverse effects of such incentives. These incentives may impair an initial motivation to work and change the norms that guide behavior. An issue which in particular has been given insufficient attention is fairness. Findings drawn from experimental economics supported by field studies demonstrate that perceived unfairness may have important negative effects on performance. The implication of a broader perspective in the analysis of performance-related pay in the public sector is that such a pay system, contrary to its aim, may have detrimental effects on performance.     

Lean road transportation – a systematic method for the improvement of road transport operations

Road transportation has become an important factor in international trade and the management of supply chains. However, this form of product logistics has generally been considered inefficient. Traditionally, practical inefficiencies of road transportation have been addressed through mathematical modelling, operations research-based methods and simulation. This paper presents an alternative systematic approach to improve road transport operations based on lean thinking and the reduction of the seven transportation extended wastes. To do this, the paper reviews the extant literature in the area of lean road transportation, providing a structured research definition of the application of lean thinking in road transport operations and hence guidance on the limited research conducted in this field. The systematic lean transportation method is then presented and empirically tested through a case study in a Mexican firm. The results obtained from the case study indicate that the proposed systematic lean method is an effective alternative for the improvement of road transport operations, with the number of distribution routes and distance travelled being reduced by 27 and 32%, respectively. The proposed method can be used by organisations as a guide to help them improve their road transport operations. In addition, the paper’s aim is to contribute by stimulating scholars to further study the application of lean thinking and waste reduction in road transport operations.     

Birds of a feather?: Firm sales growth and narcissism in the upper echelons at the CEO-TMT interface

Blending conceptual framing from the CEO-TMT interface literature with upper echelons decision-making theory, we develop a model of the role of CEO narcissism and narcissism in the upper echelons. We argue that narcissistic CEOs tend to have higher narcissism in their Top Management Teams (N-TMTs). In turn, TMTs characterized by narcissism can benefit from positive aspects of narcissism while avoiding its pitfalls; especially when strategic decision speed is slower and behavioral integration is higher. In a field study of 104 TMTs from publicly-listed South Korean firms, we find an association between narcissistic CEOs and N-TMT, and that N-TMT mediates in the indirect, conditional relationship between CEO narcissism and sales growth. We also invoke threshold theory in anticipation that outcomes associated with N-TMT may be nonlinear. In support of our threshold hypothesis, we find a curvilinear relationship between N-TMT and sales growth; and this curvilinear relationship is stronger for a small number of TMTs scoring high on N-TMT (> +2SD), where TMTs’ activities are defined by deliberative integration. The pattern of results we report provides evidence for the importance of accounting for narcissism in the upper echelons as a predictor of sales growth, and key contextual moderators of this relationship.     

Time for a revival? Public policy implementation: a review of the literature and an agenda for future research

This paper argues that there is not a vigorous contemporary literature in the UK which addresses implementation studies as part of the public policy process, whereas this is not the case in the USA. A review of the literature is presented, and a critique of the more traditional thematic groupings used to review the literature is given. A revised thematic review of the literature is presented based on the four themes of: (1) the role of knowledge and learning in policy implementation; (2) the processes of policy implementation; (3) the role of actors and agents in implementation; and (4) the role of bureaucratic discretion. The paper argues for a revival of research into public policy implementation and suggests a research agenda for the future which can use the aforementioned themes from the literature.     

Does the capital of social capital matter? Relational resources of the board and the performance of Brazilian companies

Based on theories of social capital, in this study, we seek to assess the impact of a board’s social capital on the market value of companies listed on the Brazilian stock exchange. As our indicator of social capital, we use the relational resources identified in the direct, indirect and heterogeneous ties of the board. Employing panel data from 508 observations, our results indicate that heterogeneous relational resources have a stronger and more significant influence than the resources available from board members’ direct relationships. Additionally, as the effects of board interlock are endogenously determined by several factors related to the firm level, we seek to mitigate the endogeneity problem using models of instrumental variables and simultaneous equations. Our hypotheses were consistent after controlling for endogeneity. We also check whether the board’s social capital could present a U-inverted effect on the market value. This relationship was only plausible in social capital by indirect ties. Finally, we isolate the effect of relational resources within and between industries on Tobin’s Q. There was no significant effect through interlocks within the same industry. However, ties with companies in several other industries were significant.
