The purpose of this paper is to improve the relief procurement process as one of the most important elements of humanitarian logistics. For doing so, a novel two-round decision model is developed to capture the dynamic nature of the relief procurement process by allowing demand updating. The model accounts for the supply priority of items at response phase as well.

A mixed procurement/supply policy is developed through a mathematical model, which includes spot market procurement and a novel procurement auction mechanism combining the concepts of multi-attribute and combinatorial reverse auctions. The model is of bi-objective mixed-integer non-linear programming type, which is solved through the weighted augmented e-constraint method. A case study is also provided to illustrate the applicability of the model.

This study demonstrates the ability of proposed approach to model post-disaster procurement which considers the dynamic environment of the relief logistics. The sensitivity analyses provide useful managerial insights for decision makers by studying the impacts of critical parameters on the solutions.

This paper proposes a novel reverse auction framework for relief procurement in the form of a multi-attribute combinatorial auction. Also, to deal with dynamic environment in the post-disaster procurement, a novel two-period programming model with demand updating is proposed. Finally, by considering the priority of relief items and model’s applicability in the setting of relief logistics, post-disaster horizon is divided into three periods and a mixed procurement strategy is developed to determine an appropriate supply policy for each period.

Profile of world tourism today S. Medlik gives in his publication “Trends in World Tourism” a good picture of world tourism today. This publication, together with the WTO‐publication “Tourism Compendium”, allows us to formulate a profile of world tourism today.

From an agency perspective, the authors investigate whether family ownership and control configurations are systematically associated with a firm's choice of auditor and audit fees. Agency theory is an economic theory that purposes the existence of a contract between two parties, principals and agents. Auditor choice and audit fees by family firms provide interesting insights given the unique nature of the agency problems faced by such firms.

The authors employ Big-4 auditors (PWC, KPMG, E&Y and Deloitte) as a proxy for high quality auditor (Big N) for the auditor choice model. For the audit fee model, the dependent variable is the natural logarithm of audit fees (LnAF). The authors use two measures for family firm as explanatory variables: (1) a dummy variable (FAM_Control), which equals one if the firm is classified as a family firm and (2) FAM_Ownership, which is an indicator variable with a value of one if a firm has family members who hold CEO position, occupy board seats, or hold at least 10% of the firm's equity. Data of Chinese listed firms from 2011 to 2021 are used. The authors adopt the Heckman (1979) two-stage model to mitigate the potential endogeneity issue involved in the selection of Big-N auditors.

The findings suggest that compared with non-family firms, Chinese family firms have a less tendency to employ Big-4 auditors due to less severe agency problems between owners and managers. Additionally, Chinese family firms sustain higher audit fees than non-family firms. Similar to the prior literature, however, Chinese family firms audited by Big-4 auditors incur lower audit fees than family firms audited by non-Big-4 auditors in this study. In contrast to young-family firms, old-family firms are less likely to pick top-tier auditors and sustain lower audit fees. Consistent and robust results are found from endogeneity tests and sensitivity analyses.

The empirical evidence provides a unique insight, for accounting practitioners, policymakers, family owners and other capital market participants concerning the diverse effects of various family ownership and control features on selecting high-quality auditors and audit fees. This study advances the understanding, showing that a lower demand for audit quality occurs in Chinese family firms as they encounter less severe Type I agency problems. However, the more severe Type II agency problems in Chinese family firms sustain higher audit fees due to higher audit risk and greater audit effort.

Looks at consumer research in Greater China including Mainland China, Hong Kong and Taiwan. Maps out the contributions within this area and guides future research. Examines the state of the art over the 1979‐97 period, with particular emphasis on the topics that have been researched, the extent of the theory development in the field and the methodologies used in conducting research. Uses content analysis to review 75 relevant articles. Suggests that, while a considerable breadth of topics have been researched, there remains much to be done, there is further room for theoretical development in Chinese consumer behaviour studies; and the methodologies used need improvement and further refinement.

A transport innovation has been examined through canvassing opinion from a large sample of long distance travellers. The findings proved that there was no evidence to support adopter categories in respect of the high speed train. Respondents rated the attribute “relative advantage” as being extremely relevant, whilst “trialability”, “compatibility”, “observability” and “complexity” were not particularly relevant.

The purpose of this study is to examine the influence of virtual currency (VC) development on financial stocks’ value in selected Asian equity markets and the moderating role of investor attention on this relationship.

The pooled ordinary least squares regression is used on a sample of 138 listed financial firms from four emerging Asian countries for the period 2016–2020.

This study finds that changes in VC values have greater spillover effects on the values of financial stocks in countries which do not recognize the legitimacy of VCs than in countries which do, due to the lack of breadth and depth of the former markets. Moreover, this paper also reports evidence of the greater moderating role of investor attention on this relationship in countries which do not recognize the legitimacy of VCs than in countries which do.

Although numerous studies have been conducted on the influence of VCs on stock performance, majority of these studies did not distinguish whether the sample countries being studied actually recognize the legitimacy of VC transactions or not. Moreover, extant literature has not considered the moderating role of investor attention on this relationship. It is the aim of this study to address these research voids by using a refined three-factor theory model of capital asset pricing model incorporating VCs to better represent stock performance in the digital economy era.

We explore the impact of equity liquidity on a firm’s dynamic leverage adjustments and the moderating impacts of leverage deviation and target instability on the link between equity liquidity and dynamic leverage in the UK market.

In applying the two-step system GMM, we estimate our model by exploring suitable instruments for the dynamic variable(s), i.e. lagged values of the dynamic term(s).

Our analyses document that a firm’s equity liquidity has a positive impact on the speed of adjustment (SOA) of its leverage ratio back to the target ratio in the UK market. We also demonstrate that the positive relationship between liquidity and SOA is more pronounced for firms whose current position is relatively close to their target leverage ratio and whose target ratio is relatively stable.

This study provides important implications for both firms’ managers and investors. Particularly, firms’ managers who wish to increase the leverage SOA to enhance firms’ value need to give great attention to their equity liquidity. Investors who want to evaluate firms’ performance could also consider their equity liquidity and leverage SOA.

We are the first to enrich the literature on leverage adjustments by identifying equity liquidity as a new determinant of SOA in a single developed country with many differences in the structure and development of capital markets, ownership concentration and institutional characteristics. We also provide new empirical evidence of the joint effect of equity liquidity, leverage deviation and target instability on leverage SOA.

‐ One of the consequences of the present long period of economic depression, which has been felt with particular severity by most Third World countries, has been a necessary critical reassessement of many development strategies. Especially in Africa, the balance sheet between efforts and results has not been very encouraging. The massive industrialization programmes and the large projects of the last three decades have neither helped to achieve a more competitive production nor have introduced widespread prosperity, as hoped. Gradually the accent is now shifting toward new “soft options”, one of which is tourism. We remember that only 15–20 years ago many African governments or international development agencies were still considering tourism as a marginal economic activity, to be left to poor nations without much prospects for industrialization. Since then much has changed and ‐ especially in the present post‐industrial economies ‐ tourism and the whole gamut of other leisure industries have become one of the most dynamic fields of expansion, even in the developing world.

La valorisation touristique du patrimoine bâti peut revêtir des formes très diverses, allant des pré‐occupations quotidiennes aux créations de grands mouvements intellectuels ou artistiques. Dans le même ordre d'idée, une telle valorisation peut concerner des entités géographiques et humaines de toute taille et nature, allant du hameau à la province à la nation.
