Escalation of commitment is one of the most influential decision-making biases in entrepreneurs which may incur substantial losses and result in failure by making entrepreneurs allocate an increasing amount of resources to failing plans. Not only is escalation one of the less-researched biases in entrepreneurship but also most of the existing studies have been either limited to specific contexts or exclusively limited to men entrepreneurs. The purpose of this study is to explore the antecedents of escalation of commitment among a sample of Iranian women and men entrepreneurs to address these gaps.

By conducting a narrative inquiry, data were collected through semi-structured and in-depth interviews with nine women and 10 men Iranian entrepreneurs who were founder/owners of a small business and had introduced at least one product to the market.

According to the findings of this study, the fear of losing autonomy and fear of being blamed by one’s family were the main drivers of escalation of commitment among the women entrepreneurs, while overconfidence, sense of responsibility and hoping to gain more profits were the main antecedents of escalation among men entrepreneurs.

This study is a pioneer in studying the antecedents of the escalation of commitment among women and men entrepreneurs comparatively in the context of a developing country.

This paper aims to demonstrate that Facebook likes affect outcomes in nonprofit settings. Specifically, Facebook likes influence affinity to nonprofits, which, in turn, affects fundraising outcomes.

The authors report three studies that establish that relationship. To examine social contagion, Study 1 – an auction field study – relies on selling artwork created by underprivileged youth. To isolate signaling, Study 2 manipulates the number of total Facebook likes on a page. To isolate commitment escalation, Study 3 manipulates whether a participant clicks a Facebook like.

The results show that Facebook likes increase willingness to contribute in nonprofit settings and that the process goes through affinity, as well as through Facebook impressions and bidding intensity. The total number of Facebook likes has a direct signaling effect and an indirect social contagion effect.

The effectiveness of the proposed mechanisms is limited to nonprofit settings and only applies to short-term effects.

Facebook likes serve as both a quality signal and a commitment mechanism. The magnitude of commitment escalation is larger, and the relationship is moderated by familiarity with the organization. Managers should target Facebook likes at those less familiar with the organization and should prioritize getting a potential donor to leave a like as a step leading to donation, in essence mapping a donor journey from prospective to active, where Facebook likes play an essential role in the journey. In a charity auction setting, the donor journey involves an additional step of bidder intensity.

The approach the authors study is shown effective in nonprofit settings but does not appear to extend to corporate social responsibility more broadly.

To the best of the authors’ knowledge, this study is the first investigation to map Facebook likes to a seller’s journey through signals and commitment, as well as the only investigation to map Facebook likes to charity auctions and show the effectiveness of this in the field.

Cost overrun is a significant issue in construction, an undesirable feature the industry has long been associated with. Poor procurement practices are often blamed for subsequent cost overruns in construction, especially with conventional procurement methods leading to outrageous cost overruns. The purpose of this study is to review the features of the new models of construction procurement (NMCP) and assess their potential to reduce cost overruns in construction projects.

A literature review was conducted to identify the issues of procurement leading to cost escalations. Primary data were obtained through exploratory, semi-structured interviews using a case study approach.

Clients’ lack of knowledge was highlighted as a key issue in procurement that interlinks with many factors causing cost escalation. The findings suggest that the features contained within the NMCP, such as early contractor involvement and collaboration throughout the project team, have the potential to make a positive contribution to addressing cost escalation in construction.

The primary research was undertaken as an exploratory study and presents the contractor's perspective. Further research is therefore suggested, with multiple organisations representing all key stakeholders in a construction project, including clients, consultants, sub-contractors and suppliers.

The study recommends awareness of the NMCP be raised throughout the industry, and simplified information must be made available to help widen uptake of these contemporary procurement methods.

Addressing the dearth of research concerning the use of NMCP within the industry, this study makes a niche contribution to the body of knowledge on construction cost management by illustrating the potential offered by these new procurement methods for addressing cost escalation. For an industry where collaboration is accepted with reservations, this case study demonstrates how novel collaborative strategies such as open book costing, project bank accounts and shared pain and gain mechanisms can be implemented as part of the procurement strategy and how such strategies can contribute towards minimising the cost escalation inherent in construction projects.

Decision-making biases play decisive roles not only in entrepreneurs’ decisions but also in the fate of entrepreneurial businesses. While the extant literature in this regard is relatively rich, it has predominantly focused on certain biases like overconfidence and overoptimism at the expense of other possibly influential biases, which could influence entrepreneurial decisions. Thus, to address this serious research gap, this paper aims to explore four of the less-researched biases of escalation of commitment, the illusion of control, confirmation and the belief in the law of small numbers in entrepreneurial decisions.

By taking a qualitative approach, the data for this study were collected through face-to-face interviews with 19 Iranian habitual (experienced) entrepreneurs running small businesses and analyzed by a qualitative thematic analysis.

According to the results, the environmental uncertainty, the reluctance to lose face and the experiences of previous failures contributed to the escalation of commitment, while disregard for external factors beyond one’s control caused the illusion of control, factors like prior successful businesses in the same sector, looking for resorts to manage uncertainty, along with the decision to exploit opportunities resulted in the confirmation bias, while the expenses of conducting sweeping pilot tests in the market and the reluctance to reveal a business secret to the competitors were the main contributors of the belief in the law of small numbers.

This study is a pioneer in scrutinizing four less-researched but important biases in entrepreneurs and, thus extending the line of research in this regard.

This paper aims to seek to and understand how civil conflict and international claims inform one another. Does the existence of ongoing civil and international conflicts affect how a government addresses an international claim? The paper builds on existing literature that link international and domestic conflict. However, it suggests that the logic behind civil conflicts may be different from that for international ones as states decide how to deal with any one claim.

The paper posits that states faced with domestic conflicts and additional international claims are more likely to seek to resolve an international claim than those without similar conflicts. It develops a series of hypotheses about the likelihood of claim escalation and peaceful settlement attempts and proceed to test them quantitatively using the Issue Correlates of War data combined with the uppsala conflict data program/peace research institute oslo Armed Conflict Data.

On the one hand, the paper finds support for the argument regarding the difficulty states are faced with when seeking to resolve multiple international claims. On the other hand, it finds that the presence of civil conflicts incentivizes states to resolve international claims either by force or peacefully, suggesting internal violence can both lead to diversionary behavior and attempts at conflict resolution.

The findings have important implications for work considering the complexity of domestic and international conflict linkages.

While many studies of claim militarization and peaceful attempts focus on dyadic and international characteristics, this paper creates a more nuanced understanding of the complexities of this foreign policy decision process.

The earth is facing challenges to work for the survival of human life during domino effect disasters. The emergency resource storage locations should be selected considering the probability of domino effect disasters. The first purpose of this study is to select the storage locations where domino effect probability is less. And second, facility development cost and transportation costs and costs for unutilized capacity have been optimized.

The work is a multiobjective optimization problem and solved with weighted sum approach. At first, the probabilities of domino effect due to natural disasters are calculated based on the earthquake zones. Then with that result along with other necessary data, the location to set up storage facilities and the quantities of resources that need to be transported has been determined.

The work targeted a country, Bangladesh for example. The authors have noticed that Bangladesh is currently storing relief items at warehouse which is under the domino effect prone region. The authors are proposing to avoid this location and identified the optimized cost for setting up the facilities. In this work, the authors pointed out which location has high probability of domino effect and after avoiding this location whether cost can be optimized, and the result demonstrated that this decision can be economical.

Disaster response authorities should try to take necessary proactive steps during cascading disasters. The novelty of this work is determining the locations to select storage facilities if the authors consider the probability of the domino effect. Then a facility location optimization model has been developed to minimize the costs. This paper can support policymakers to assess the strategies for selecting the location of emergency resource facilities.
