In recent years, some peer-to-peer (P2P) service sharing platforms have improved their service quality by setting an entry quality threshold for service providers. Considering consumers' heterogeneous preferences for service quality and commission rate, it is worth studying how to select the commission rate contract for a P2P platform under a predetermined entry quality threshold for service providers.

In this study, the platform's profit-maximizing model is constructed under two proposed contracts: unilateral commission rate contract and bilateral commission rate contract. The optimal entry quality threshold and the optimal commission rate are obtained. This study also explores the impacts of cross-side network externality and service price on a platform's optimal decisions and social welfare.

Results show that it is always advantageous for the platform to adopt the bilateral commission rate contract, which is closely related to the strength of cross-side network externality, service price and quality sensitivity coefficient. Under certain conditions, adopting the unilateral commission rate contract can reduce platform profit and service provider surplus, and improve consumer surplus and social welfare.

This study analyzes the unilateral commission rate contract and the bilateral commission rate contract of the platform, and discusses which contract is beneficial to the platform, consumers and service providers. In addition, this study provides a basis for the operation decision of a P2P service sharing platform and the pricing decision of service providers.

Economics is catering to a diverse student cohort. This cohort needs to be equipped with transformative concepts that students can integrate beyond university. When a curriculum is content-driven, threshold concepts are a useful tool in guiding curriculum re-design. The paper aims to discuss these issues.

The evidence for this pedagogic need can be seen in the UK’s higher education economics curriculum framework which is formulated around the threshold concepts of economics. Through a literature review of the application of threshold concepts in economics, the researcher has systematically re-designed an entry-level economics course. This research has been applied to the course structure, the learning and teaching activities, as well as the assessments. At the end of the semester, students students were surveyed on the student experience of the curriculum design and the course activities. The course grades noted the achievement of the students’ learning outcomes.

When comparing the survey responses and the student course results to the previous semesters, there is a significant improvement in student experience as well as student learning outcomes of the course curriculum.

This research provides curriculum developers with a benchmark and the tools required to transform economics curricula.

An engaging, transformative and integrative entry-level economics course is often the only exposure most business graduates have to the economics way of thinking and practice.

This is the first comprehensive study that applies a curriculum re-design based on threshold concepts across an entry-level economics course.

The single-most important parameter of a public procurement system is the threshold above which the framework applies. The optimization problem consists of finding a reasonable trade-off between the gains from public procurement and the administrative costs associated with procurement rules. In the present study, based on a sample of central and local government procurement operations in Sweden, an optimal threshold value in the range of 5,000—6,000 EUR is computed based on the requirement that the average gain should supersede the average cost. If a larger proportion of procurements is required to gain from the regulation imposed, a threshold value of 20,000—25,000 EUR should apply. The general conclusion is that there are strong arguments for maintaining procurement rules below the European Union threshold.

Farmers often decide simultaneously on crop production or input use without knowing other farmers' decisions. Anticipating the behavior of other farmers can increase financial performance. This paper investigates the role of other famers' behaviors and other contextual factors in farmers' simultaneous production decisions.

Market entry games are a common method for investigating simultaneous production decisions. However, so far they have been conducted with abstract tasks and by untrained subjects. The authors extend market entry games by using three real contexts: pesticide use, animal welfare and wheat production, in an incentivized framed field experiment with 323 German farmers.

The authors find that farmers take different decisions under identical incentive structures for the three contexts. While context plays a major role in their decisions, their expectations about the behavior of other farmers have little influence on their decision.

The paper offers new insights into the decision-making behavior of farmers. A better understanding of how farmers anticipate the behavior of other farmers in their production decisions can improve both the performance of individual farms and the allocational efficiency of agricultural and food markets.

One of the main obstacles to the flourishment of African entrepreneurship is financial constraint. Existing studies on the nexus between entrepreneurship and financial development are inconclusive, while the position of African economies remains unknown. The purpose of this paper is to empirically study the impact of financial development on entrepreneurship in Africa.

This study utilizes data of 20 selected countries in Africa over a period of 2006–2017. International Monetary Fund (IMF) data on broad-based financial development were combined with World Bank Entrepreneurship database. This study uses system generalized methods of moments (system GMM) technique and the recently developed dynamic panel threshold based on dynamic panel GMM.

The following findings emerged: financial development does not spur entrepreneurship in Africa; there is a threshold at which financial development improves the level of African entrepreneurship; and the tendency of financial development to improve the level of entrepreneurship is conditioned on conducive business regulation and strong institutional quality at a specific threshold value.

This is one of the few studies that examines the impact of financial development on entrepreneurship in Africa. This study shows that the financial development relies on the effectiveness of regulatory environment to extend loan and other financial services to new firm entrants. In addition, the results of this study reveal that the assumption of linearity in the nexus between finance and entrepreneurship is not tenable for the case of Africa. Therefore, policymakers should keep on developing African financial system to accelerate the pace of entrepreneurship development.

The purpose of this paper is to estimate whether job applicants who have obtained a BSc in economics from 15 UK universities face different labour market prospects. The author examines whether university entry standards and Russell Group membership affect UK economics applicants’ occupational access and entry-level annual salaries when unobserved heterogeneities, such as ability, motivation, family characteristics and networks, are minimized.

The author evaluate the research question by recording the job search processes of 90 British economics applicants from randomly selected universities. The key elements of the approach are as follows: third-year undergraduate students apply for early career jobs that are relevant to their studies. Applications are closely matched in terms of age, ethnicity, experience and other core characteristics. Differential treatment in the access to vacancies and entry-level annual salaries per university applicant are systematically measured.

By observing as much information as a firm does, the estimations suggest that both entry standards and Russell Group membership positively affect applicants’ labour market prospects. Although the firms cannot evaluate by themselves whether graduates from highly reputable universities are more or less capable and motivated than graduates from less reputable universities, it appears that the university attended affects firms’ recruitment policies. Importantly, valuable variables that capture firms’ and jobs’ heterogeneities, such as occupational variation, regions, workplace size, establishment age, and the existence of trade unions and human resources, are also considered and provide new results.

Understanding the impact of entry standards and university reputation on students’ labour market outcomes is critical to understanding the role of human capital and screening strategies. In addition, obtaining accurate estimates of the payoff of attending a university with a high entry threshold and reputation is of great importance not only to the parents of prospective students who foot tuition bills but also to the students themselves. Furthermore, universities will be interested in the patterns estimated by this study, which will allow recent UK economists to evaluate the current employment environment. In addition, universities should be keen to know how their own graduates have fared in the labour market compared with graduates of other universities.

In the current study, the author attempt to solve the problem of firms’ seeing more information than econometricians by looking at an outcome that is determined before firms see any unobservable characteristics. In the current study, ability, motivation, family characteristics and networks cannot affect applicants’ access to vacancies and entry-level salaries. The current study can estimate the effect of university enrolment on applicants’ occupational access and entry-level salaries, controlling for unobserved characteristics that would themselves affect subsequent outcomes in the labour market.

The paper aims to study the role of local institutions in the establishment of fast-food outlets in urban districts of Peru. In most urban districts, there are no fast-food outlets. The authors, therefore, study the effect of institutional quality on the presence or absence of these outlets and the number of outlets if these are present.

The theoretical framework in which this paper is based on is the theory of agglomeration, which establishes that firms benefit from being close to each other. In particular, the paper builds on a model of market entry and competition in geographically independent local markets. An explicit expression was found for the equilibrium number of outlets (including zero) as a function of exogenous determinants of the demand for fast-food in each market, available infrastructure and institutional quality of the district’s government. Principal component analysis was used to construct measures of institutional quality based on administrative and organizational characteristics of district’s municipalities. These measures were incorporated as explanatory variables in a zero-inflated Poisson model, which is appropriate to handle count data and to accommodate excess zeros and which also allows the specification of different models for the zero part and the positive part.

Institutional quality mainly affects the presence of fast-food outlets in a district. The quality of urban development management and use of information systems are relevant. An institutional variable particularly relevant in explaining the number of outlets is the presence of an investment programming office in the municipality. The authors confirm the general hypothesis of the paper: institutions have a role in explaining both the presence and number of fast-food outlets in a district. Overall, the results of this paper suggest that institutional quality of a municipal district is related to better infrastructure, which lowers the costs of establishing outlets.

Limitations in the availability of data at the regional and urban district level did not allow the authors to analyze other factors that affect entry decisions in the fast-food industry in Peru, such as controls to prevent corruption, legal uncertainty or crime. Another limitation was the lack of data on entry costs for each franchisee in each urban district. This forced the authors to use public infrastructure characteristics of the district as (imperfect) proxies of the entry costs.

The instruments of urban development management and information systems can be effective at attracting investment to a district. These tools operate partly through an indirect effect, namely, the improvement of district infrastructure, which is necessary to reduce the costs of establishing companies. There is also synergy between national government’s programs to attract investment and the good institutional quality in local governments. On the contrary, poor local institutions can be an obstacle to the successful implementation of those national programs.

Foreign direct investment has a positive impact on the economic development of a country through knowledge spillovers. Therefore, any administrative reform to make local government practices more efficient can have an indirect impact on development.

Principal component analysis is a statistical tool that can be important in building good measures of institutional quality by allowing the combination of different observable characteristics into one component that can be interpreted as an operational restriction. The count model allows the use of the primary, easily observable, dependent variable, namely, the number of outlets. Finally, the two-part model makes it possible to discern the effect of institutional quality on the presence or absence of outlets and the number of outlets if these are present.

The Bureau of Economics in the Federal Trade Commission has a three-part role in the Agency and the strength of its functions changed over time depending on the preferences and ideology of the FTC’s leaders, developments in the field of economics, and the tenor of the times. The over-riding current role is to provide well considered, unbiased economic advice regarding antitrust and consumer protection law enforcement cases to the legal staff and the Commission. The second role, which long ago was primary, is to provide reports on investigations of various industries to the public and public officials. This role was more recently called research or “policy R&D”. A third role is to advocate for competition and markets both domestically and internationally. As a practical matter, the provision of economic advice to the FTC and to the legal staff has required that the economists wear “two hats,” helping the legal staff investigate cases and provide evidence to support law enforcement cases while also providing advice to the legal bureaus and to the Commission on which cases to pursue (thus providing “a second set of eyes” to evaluate cases). There is sometimes a tension in those functions because building a case is not the same as evaluating a case. Economists and the Bureau of Economics have provided such services to the FTC for over 100 years proving that a sub-organization can survive while playing roles that sometimes conflict. Such a life is not, however, always easy or fun.

This paper aims to explain how the dynamic demand environment influences strategic firm behavior along an industry’s evolutionary path. A conceptual gap concerning the influence of demand-side environmental factors (vis-à-vis changes in technology and policy) on firms’ strategic choices motivates the theory developed herein. The paper’s contribution to the literature on “evolutionary perspective in strategy” also addresses an important gap in the emerging literature on “strategy dynamics”.

The conceptual framework in this paper features a dynamic demand environment that provides the structural context for firms’ strategic choices. It conceptualizes demand-side competence as a mediating firm-specific construct to explain the endogenous relationship between the characteristics of the demand environment and firms’ path dependent demand-side investments.

A review of the literature on evolutionary perspective in strategy reveals an important conceptual gap concerning the structural determinants of dynamic firm behavior. There is no explanation of the endogenous relationship between dynamic demand structure, firms’ dynamic demand-side competence, and temporally heterogeneous strategic choices.

The demand-side explanation of how idiosyncratic firm behavior is endogenously determined, with both structural characteristics (demand structure) and firm competences (demand-side competence), addresses an important conceptual gap. The novelty of the theory developed herein lies in its explication of the effect of dynamic demand environment on the evolution of idiosyncratic strategic firm behavior – entry, investment and exit – along the evolutionary path of an industry. The theory developed herein not only explains the effect of both determinants of idiosyncratic strategic firm behavior – the external industry environment (dynamic market structure) and internal firm environment (dynamic firm competences) – but also explains how the determinants evolve along the industry’s lifecycle.

Peer‐to‐peer (P2P) streaming quickly emerges as an important application over the internet. A lot of systems have been implemented to support peer‐to‐peer media streaming. However, some problems still exist. These problems include non‐guaranteed communication efficiency, limited upload capacity and dynamics of suppliers which are all related to the overlay topology design. The purpose of this paper is to propose a novel overlay construction framework for peer‐to‐peer streaming.

To exploit the bandwidth resource of neighboring peers with low communication delay, application of the grouping method was proposed to construct a flexible two‐layered locality‐aware overlay network. In the proposed overlay, peers are clustered into locality groups according to the communication delays of peers. These locality groups are interconnected with each other to form the top layer of the overlay. In each locality group, peers form an overlay mesh for transmitting stream to other peers of the same group. These overlay meshes form the bottom layer of the overlay.

Through simulations, the performance was compared in terms of communication efficiency, source‐to‐end delivery efficiency and reliability of the delivery paths of the proposed solution currently. Simulation results show that the proposed method can achieve the construction of a scalable, efficient and stable peer‐to‐peer streaming environment.

The new contributions in this paper are a novel framework which includes the adaptability, maintenance and optimization schemes to adjust the size of overlay dynamically according to the dynamics of peers; and considering the importance of locality of peers in the system.
