The paper aims to compare the efficiency of alternative municipal solid waste (MSW) management business models: a single provider against multiple providers.

In this paper the drivers of MSW management costs are analysed to test the impact of the scale and scope of MSW management services on the average cost. While the business-as-usual scenario foresees a single provider, the alternative scenario foresees multiple providers.

Based on the empirical data on municipal waste management costs, on average, the size and the average cost of the service are inversely related. This trend is supported using sub-sets defined by the quantity of waste managed. Multiple factors aid in explaining this result, and among others, due to scale and scope, factors such as transition costs increase with the number of players running different services.

The provision of public services of economic interest should favour the participation of more companies wherever possible to the extent that social surplus is produced. However, pursuing this principle to the detriment of efficient service delivery is not ideal. This paper demonstrated that a single-provider waste management business model is efficient under specific conditions, as in this article.

This paper presents an original research methodology for comparatively analysing waste management service efficiency in urban areas and provides adequate evidence using alternative measures of costs according to the phase of the waste management chain, the scale and ultimately the scope of MSW management services.

本學術論文擬比較另類的都市固體廢物管理模式的效率, 比較的對像是:單一服務提供者和多個提供服務者。

研究人員分析都市固體廢物管理成本和價格的動因, 以測試有關的管理服務之規模和範圍對平均成本的影響。若在一切照常的情況下, 我們會預見單一服務提供者, 唯在不尋常的情況下, 我們則會預見多個提供服務者。

根據都市廢物管理價格和成本上的實證數據, 平均而言, 服務的規模與其平均成本是成反比的。我們使用了以所處理之廢物量來界定的子集來支持這趨勢。多重因素會幫助解釋和說明這研究結果, 其中包括:因規模和範圍的關係, 諸如過度成本等的因素, 會按著提供各種不同服務的主要參與者的數目而增加。

在能達創造社會剩餘的前題下, 會帶來經濟效益之公共服務的提供, 應有利於在可行範圍內有更多公司的參與; 但如果實行這原則而因此有損於服務提供的效率的話, 則這是不理想的。本文展示了在特定的情況下, 單一服務提供者的廢物管理商業模式是高效率的, 本文已說明這些特定情況。

本文為以比較分析法去探討城市地區廢物管理服務的效率、提出了一個新穎的研究方法, 並根據廢物管理鏈的階段、都市固體廢物管理服務的規模、以及最終其範圍, 考慮了成本和價格的另類測量方法, 繼而提供充分的證據, 以支持這些測量方法。

The International Labor Organization (2020) estimates that eight out of ten enterprises (i.e. own-account workers and small economic units) are informal worldwide. However, less is known about the internationalization of informal enterprises. Here, it is argued that economic blocs, such as sub-Saharan Africa, with a greater proportion of informal enterprises, may provide broader societal legitimacy for them to operate internationally. Thus, informal firms would need to collaborate with other firms to overcome their resource constraints. Geographic colocation is one way to facilitate positive interfirm interactions that promote networking and subsequently cooperation. The purpose of this paper is, thus, to addresses two questions. Firstly, how and to what extent does interfirm marketing cooperation in geographic colocation influence the internationalization of micro and small informal manufacturing enterprises? Secondly, how do the perceived benefits of local external economies moderate this relationship?

The study draws evidence from 125 randomly selected informal enterprises located in two major clusters in Ghana, using a mixed-method approach.

The partial least square - structural equation modeling (PLS-SEM) analysis applied revealed two central points. Firstly, sharing marketing costs allows informal firms to upgrade their phases of export development directly. Secondly, the linkage of increasing sales activities and local external economies encourages the progress of the phases of export development and the scope of internationalization. Results confirm that the cluster benefits of interfirm cooperation and local external economies on the informal firm internationalization process complement each other in addition to their linear relationship.

The study contributes to understanding the nexus of the informal sector, geographic colocation and the entrepreneurial internationalization literature. The results should motivate researchers and policymakers to approach informal firm internationalization through collaborative business activities.

Social media networks make their services freely available to all users. Users pay for the service received with the time and attention taken by the advertisements. This chapter argues that social media platforms are a unique form of monopoly driven by “the more the merrier” effect (i.e., network effects) in users' consumption. These monopolies exercise market power, not by charging higher prices to users but by “tying” larger amounts of advertising to their content. Traditional antitrust instruments designed to address excessive pricing and reduced output by monopolies need to be reframed to tame the attention economy problems in the social media industry. This chapter discusses five antitrust instruments grouped in three categories: structural, behavioral, and market-based remedies. Market-based solutions are the least explored in the literature, despite being the most promising instruments to lower the attention costs imposed on users, while preserving the economies of scope in production and the network effects in consumption, and possibly maintaining free access to social media, as we know it today.

The creation of positive social change (PSC) is considered the primary success criterion when evaluating social enterprise performance. However, despite a proliferation of PSC-measurements, their empirical validity and applicability in emerging economies remain largely unclear. The quantitative study examines the validity of the PSC-measurement approaches proposed by Bloom and Smith (2010; Bloom and Smith approach [BSA]) and Weaver (2020b; Weaver approach [WA]) in South Africa.

Investigating a representative sample of 347 social entrepreneurs from Gauteng and Limpopo provinces, the authors use questionnaire data to explore the factorial, convergent and discriminant validity of both PSC-measurement approaches. Statistically, this is done by applying factorial and correlation analyses.

The results yield acknowledgeable differences. BSA has a high factorial and convergent validity, while its discriminant validity remains doubtful. For WA, problems concerning factorial validity occur.

Despite limited generalizability, the authors provide a first guideline for scholars regarding the empirical validity of BSA and WA outside the context of developed economies.

The current study sheds light on the validity of two PSC-measurement approaches in an emerging economy context. This way, the authors contribute to the field by addressing the scarcity of empirical research and the restricted scope of developed economies regarding PSC-measurement.

Today's sharing economy covers a variety of business models. This research aims to (1) identify dimensions along which sharing businesses may vary and (2) investigate how these dimensions influence consumer engagement while considering consumers' sustainability orientation.

This research relies upon a systematic literature review (n = 67 articles) to identify five sharing business dimensions: (1) ownership transfer, (2) professional involvement, (3) compensation, (4) digitalization and (5) community scope. A discrete choice conjoint experiment in the fashion industry is employed to investigate how these dimensions affect consumer engagement with sharing businesses (n = 383 participants).

The results suggest that ownership of tangible resources elicits more engagement than access to tangible resources for both consumers with a low sustainability orientation and consumers with a high sustainability orientation. Community scope also affects consumer engagement as reflected in more engagement towards sharing businesses with a local rather than a global scope. The presence of professional service providers, monetary compensation and a digital platform only induces engagement among consumers with a low sustainability orientation.

This research generates a better understanding of how sharing businesses can draw on business dimensions to engage consumers with different levels of sustainability orientation and, in turn, how sharing businesses can realize their economic and/or circular potential.

We make use of rich microdata from the Belgian MEqIn survey, which contains detailed information on individual consumption, public consumption inside households, and time use. We explain the observed household behavior by means of a collective model that integrates marriage market restrictions on intrahousehold allocation patterns. We adopt a revealed preference approach that abstains from any functional form assumptions on individual utility functions or intrahousehold decision processes. This allows us to (set) identify the sharing rule, which governs the intrahousehold sharing of time and money, and to quantify economies of scale within households. We use these results to conduct a robust individual welfare and inequality analysis, hereby highlighting the important role of detailed consumption and time use data.

This paper aims to assess how big data–driven supply chain management (BDSCM) influences sustainable supply chain management (SSCM) to achieve sustainable corporate performance (SCP) for small and medium-sized enterprises (SMEs) in an emerging economy such as Vietnam, besides exploring whether Circular Economy Thinking Application (CETA) moderates the relationship between BDSCM and SSCM.

This study collected survey data from 495 SMEs in the food supply chain sector. It employed the PLS-SEM (Partial Least-Squares Structural Equation Modeling) technique to evaluate the hypothesized relationships.

This study found that BDSCM positively, directly and indirectly, impacted SCP. SSCM partially mediated the correlation between BDSCM and SCP. Additionally, CETA moderated the relationship between BDSCM and SSCM. CETA had a direct and positive effect on SSCM.

The insights into how BDSCM influences SSCM to achieve SCP for SMEs in the food value chain in an emerging economy like Vietnam provides an original value. Moreover, the novelty of this study is further reinforced by the coverage of the newfound mechanism, where CETA moderates the relationship between BDSCM and SSCM, directly and positively enhancing SSCM. These contributions could interest business practitioners and academics.

During the Communist Party of China's endeavors over the past century, China has created “two miracles,” namely, large-scale and rapid economic development and long-term social stability.

The causes for China's achieving the “two miracles” lie in the adherence to the Party's leadership as the political guarantee, the scientific theoretical guidance as the ideological guarantee, the socialist system as well as the national governance system as the institutional guarantee and giving full play of people's creativity under the Party's leadership as the driving force guarantee.

From a political economy point of view, the theoretical logic behind the creation of the “two miracles” is that the combination of the state capacity and the scaling up of markets under the Party's leadership contributes to the rapid economic development and further the long-term social stability based on the financial foundation laid by rapid economic development. The historical experience of the “Two Miracles” can be summed up as the cultivation of state capacity under the leadership of the Party, the synergy and complementarity between the central government and local governments, the combination of development planning and market mechanisms, and the coordination of selective, functional and inclusive industrial policies.

It is necessary to judge future development trends from a medium and long-term development perspective, further promote the co-evolution of the state and the market, reshape the growth regime for high-quality development, fully tap the potential of domestic demand and create a “people-centered” economic development model so as to continue the “two miracles” and achieve a miracle of high-quality development in the second century.
