Truthful germs are contagious: A local-to-global characterization of truthfulness

We study the question of which social choice functions from an abstract type space to a set of outcomes are truthful, i.e., implementable by truthful mechanisms, when utilities are quasi-linear. For convex domains, our main theorem characterizes truthful social choice functions as those satisfying two properties: local weak monotonicity and vortex-freeness. The first of these constrains the function values at any two sufficiently proximal points, while the second asserts that its line integrals around sufficiently small triangular loops must vanish.The characterization implies a local-to-global principle that allows one to deduce truthfulness of a function from its behavior on arbitrarily small neighborhoods of each point. Other consequences include a simple alternate derivation of the Saks–Yu Theorem that weak monotonicity characterizes truthfulness of functions having a convex domain and finite range, and a sufficient condition for constructing truthful functions by “stitching together” truthful subfunctions on different subsets of the domain.     

论历史逻辑

Informing timeshare exchange services on the drivers of customer-driven co-production

Given the continued growth of the timeshare segment and its unique characteristics as an owned leisure lodging product, adopting a service-dominant logic and developing opportunities for co-creation is highly relevant for companies that provide services to this industry. Specifically, the purpose of this study is to explore the drivers that lead to customer-driven co-production in timeshare exchange services, due to the popularity of this option among consumers owning timeshare. Our results indicate that interaction between timeshare owners as customers of the exchange company is a significant driver of customer-driven co-production. To the authors’ knowledge, this is the first study to explore customer-driven co-production in the timeshare industry. Moreover, our findings are highly significant for timeshare exchange companies and point them to potential areas of improvement in their service processes that could lead to higher customer-driven co-production and, consequently, more valuable experiences.     

Export Performance: Is It Possible through Knowledge and Capabilities? Evidence from Turkish Manufacturing Firms

Purpose: This article measures to what extent export performance is affected by certain resource-based view (RBV) elements and seeks to elucidate relationships between these elements. Design: Among those RBV elements, knowledge and experience as resources, and marketing, production, product development, logistics, and service differentiation as capabilities, are chosen to be the basis of this research. Their effects on export performance are measured with a survey applied to personnel of Turkish manufacturing firms operating in Istanbul district. Findings: The results show us that marketing planning capabilities and service differentiation capabilities have a significant effect on export performance. The overwhelming effect of knowledge and experience of firms on marketing planning capabilities is one of the intriguing findings. Notwithstanding that, we found no trace of a relationship between product development capabilities and service differentiation capabilities. Value: This research provides several managerial and academic implications by contributing to a resource-based view in terms of knowledge and capabilities. Additionally, in this study, it is underlined that collective knowledge is vital for achieving high export performance.     

Corporate sustainability strategies in institutional adversity: Antecedent,outcome, and contingency effects

This study examines (i) how top-level managerial institutional ties drive corporate sustainability strategies of emerging market firms operating under conditions of institutional adversity; (ii) the impact of corporate sustainability strategies on market performance; and (iii) the moderating role of financial resource slack on the relationships between corporate sustainability strategies and market performance. The study builds from institutional development logic and the structure–conduct–performance paradigm. Primary data are collected from 300 firms operating in a major sub-Saharan African market. Findings show that top-level managerial institutional linkages with regulatory national governmental officials, local community leaders, and top managers at other firms drive corporate proactive and responsive sustainability strategies, which in turn influence market performance. In addition, the findings reveal that financial resource slack strengthens the path between corporate proactive sustainability strategies and market performance, but not the path between corporate responsive sustainability strategies and market performance. Theoretical and practical implications are discussed.     

Assessing Systemic Importance With a Fuzzy Logic Inference System

Three metrics are designed to assess Colombian financial institutions' size, connectedness and non-substitutability as the main drivers of systemic importance: (i) centrality as net borrower in the money market network; (ii) centrality as payments originator in the large-value payment system network; and (iii) asset value of core financial services. An aggregated systemic importance index is calculated based on expert knowledge by using a fuzzy logic inference system. We use principal component analysis to calculate a benchmark index for comparison purposes. Overall similarities between both indexes put forward that expert knowledge aggregation is consistent with that based on a purely quantitative standard approach. Specific non-negligible differences concur with the nonlinear features of an approach whose intention is to replicate human reasoning. Both indexes are complementary and provide a comprehensive relative assessment of each financial institution's systemic importance in the Colombian case, in which the choice of metrics pursues the macroprudential perspective of financial stability.

Customer Roles in Self-Service Technology Encounters in a Tourism Context

This paper reports on a study which explored the customer perspective on their roles in SST encounters in a tourism context, through the theoretical lens of service-dominant logic. The study employed short qualitative interviews with airline passengers at an international airport. The findings suggest that customers can assume six roles in an SST encounter which can be viewed as either positive or negative in terms of value creation. Therefore, a key contribution of this paper is the development of a role–experience continuum which depicts the variations in customer experiences of value creation in a tourism context.     

An Epistemological Reflection on Social and Solidarity Economy

Social and Solidarity Economy (SSE) is emerging as life affirming solutions to the global crises through the multiple ways people locally reinvent economic life on the margins of the capitalist system based on values of solidarity, reciprocity and sustainability. Although the SSE builds on a strong foundation of real practices and institutions of economic transformation as the way forward for us, this paper argues that this world of practice is in need of its theory to frame discourses and engage with the bigger picture with confidence as an alternative to the dominant economic paradigm. The author argues that the orthodox economics, with its ontological construct of the homo economicus, Cartesian dichotomy and logical positivist epistemology severely constrains our abilities to understand and appreciate economic alternatives based on ‘other’ rationalities. Hence, there is a need for an epistemological revolution to construct a coherent theoretical framework from the wreckages of the neoclassical economics for the SSE. This paper seeks to outline the basic structure and the key elements of the ontological and the epistemological framework for this ‘science-in-the-making’ as a step to stimulate further debate for a paradigm revolution.     

Reconceptualizing value creation: Exploring the role of goal congruence in the Co-creation process

As companies gradually shift from the exchange view to the resource integration view, the creation of value also shifts from the customer sphere to the joint sphere. As a result, the customer and service provider are responsible for co-creating value through resource integration. However, it raises the question of whether customers are capable of contributing to the co-creation of value. Our study proposes a framework of how goal congruence plays a pivotal role in the resource integration process between all actors in the joint sphere. When the level of goal congruence between customer and service provider actors is high, it stimulates the exchange of valuable resources from all actors, which leads to the actual experience of co-creation resulting in value-in-use and improves service outcomes, i.e., customer satisfaction and loyalty. Data were collected through a field survey from salon-and-spa customers (n = 530) and PLS-SEM was employed to test the hypotheses and further analysis. The results show that goal congruence impacts customer satisfaction and loyalty through value-in-use. Therefore, suggesting service providers to properly socialize their goals will be a good strategy to increase customer capability to co-create value and ultimately enhance customer satisfaction and loyalty.     

大国治理逻辑下地方公共收入机制的构建——基于公共物品有效供给分析

分税制框架下的现行地方公共收入机制,无论从增长效应还是从公平效应看,其制度设计均不利于促成地方政府有效供给公共物品。基于大国治理逻辑的一个理论基石是,促成公共物品有效供给的地方公共收入机制,需要融合独立性财权与权力制衡机制。据此,结合受益原则与支付能力原则,利于公共物品有效供给的地方公共收入机制构建,应在不触动当前政府间财政制衡设计的框架下,围绕权力确定、来源清晰,负担落实、征管优势、适度弹性原则,注重财产税、使用者费、地方公债三大收入形式的运用,并借助制度调整来增强地方独立性财权。
