Abstract
Purpose
The authors characterize the conditions under which a country may eventually split and when it splits within an infinite horizon multi-stage differential game.
Design/methodology/approach
In contrast to the existing literature, the authors do not assume that after splitting, players will adopt Markovian strategies. Instead, the authors assume that while the splitting country plays Markovian, the remaining coalition remains committed to the collective control of pollution and plays open-loop.
Findings
Within a full linear-quadratic model, the authors characterize the optimal strategies. The authors later compare with the outcomes of the case where the splitting country and the remaining coalition play both Markovian. The authors highlight several interesting results in terms of the implications for long-term pollution levels and the duration of coalitions under heterogenous strategies as compared to Markovian behavior.
Originality/value
In this paper, the authors have illustrated the richness of the simplications of enlarging the set of strategies in terms of the emergence of coalitions, their duration and the implied welfare levels per player. Varying only three parameters (the technological gap, pollution damage and coalition payoff share distribution across players), the authors have been able to generate, among other findings, quite different rankings of welfare per player depending on whether the remaining coalitions after split play Markovian or stay precommited to the pre-splitting period decisions.

Abstract
The growing displacement of theory and other forms of wide-ranging knowledge of social phenomena by empirical research methods in economics is widely noted by economists and historians of economic knowledge. Less attention has been devoted, however, to understand the materialization of such changes in the scientific practices. This article studies the recent transformations in the epistemological practices at CEDE, a research center in Colombia. I use a machine learning technique called Topic Modeling, interviews to CEDE researchers, and exegesis of papers to characterize a shift in the production of knowledge in microeconometrics at CEDE during the years 2000 and 2018. I explain this shift by characterizing two sets of epistemological practices that implies a recent tendency to disdain research that cannot make a “strong” causal inference.

The purpose of this paper is to improve the classification of families having children with affective-behavioral maladies, and thus giving the families a suitable orientation.
Abstract
Purpose
The purpose of this paper is to improve the classification of families having children with affective-behavioral maladies, and thus giving the families a suitable orientation.
Design/methodology/approach
The proposed methodology includes three steps. Step 1 addresses initial data preprocessing, by noise filtering or data condensation. Step 2 performs a multiple feature sets selection, by using genetic algorithms and rough sets. Finally, Step 3 merges the candidate solutions and obtains the selected features and instances.
Findings
The new proposal show very good results on the family data (with 100 percent of correct classifications). It also obtained accurate results over a variety of repository data sets. The proposed approach is suitable for dealing with non-symmetric similarity functions, as well as with high-dimensionality mixed and incomplete data.
Originality/value
Previous work in the state of the art only considers instance selection to preprocess the schools for children with affective-behavioral maladies data. This paper explores using a new combined instance and feature selection technique to select relevant instances and features, leading to better classification, and to a simplification of the data.

Abstract
Purpose
Higher education institutions have a significant impact in preparing future generations for the creation of a sustainable society. By formulating appropriate curricula, the university can shape student personality with sustainability concerns. This study aims to present the results of a teaching approach on environmental sustainability using the photovoice methodology. A guided visit to the sewage treatment plant of A Coruña was included as a teaching activity in the “Microbiology and Parasitology” classes of the podiatry degree at University of A Coruña. The teaching objectives were to reinforce contents through observation and to introduce citizen awareness on sustainability and responsible water use in a cross-sectional manner.
Design/methodology/approach
In this case study, different steps of photovoice as a qualitative participatory action methodology were developed. A total of 43 university students willingly participated with their photographs. Qualitative data were collected from the students’ photovoice visit reports and a subsequent discussion group. Thematic content analysis was performed manually.
Findings
This study explored the impact of an environmental sustainability teaching activity on the university student community. Six main categories emerged from the qualitative analysis: savings/waste of water, misuse of the water closet, disposing of used oil, solid waste/trash, reuse of clean water and reuse/reduction of the use of plastics. The cross-sectional findings on the needs of education and awareness of sustainability in the community and companies are presented.
Originality/value
The findings provide evidence of the ability of photovoice method as a pedagogical tool to promote reflection and change in the university community and to introduce sustainability cross-sectional content in green campus curricula. This photovoice experiment is simple and feasible to implement and has a very low economic cost, as long as there are qualified educators.

Abstract
Purpose
Consumers’ underlying motives to co-create value are important when determining their willingness to engage in co-creation activities. However, the importance of their motives may vary according to different service contexts. The purpose of this paper is to contribute to the value co-creation research by investigating how the service contexts shape consumers’ motives to co-create.
Design/methodology/approach
This paper is based on a survey of 284 consumers. By focusing on professional vs generic services (context), based on differences in knowledge intensity and workforce professionalism, the paper pinpoints the contextual nature of consumer motives to co-create.
Findings
The results show that in professional services consumers are positively influenced to co-create by developmental motives, whereas empowerment motives have a negative impact. In turn, the positive effects of individualizing and relating motives are predominant in generic services. Willingness to co-create is a strong determinant of intended co-creation behaviors, regardless of the service type.
Research limitations/implications
This study clearly shows the contextual nature of motives to co-create value, thereby questioning the generalizability of single-context studies.
Originality/value
This is the first paper to compare consumer motives to co-create across different service contexts.

Abstract
This paper examines the impact of the assassination of Mexico’s leading presidential candidate on Mexican Brady bonds and its spillover effects to other emerging financial markets. On the day of the assassination, Mexican Brady bonds declined by a significant 0.97 percent and continued to experience significant declines over the following three trading sessions. However, with the naming of Ernesto Zedillo as the ruling party’s presidential candidate, Mexican Brady bonds recovered over 75 percent of the losses incurred during the previous four trading days. The assassination did not significantly affect other emerging financial markets. The availability of a $6 billion swap facility, holding of large foreign reserves, selection of Ernesto Zedillo, and well managed responses by the Mexican government all served to attenuate spillover effects from the Mexican political crisis.

Abstract
Purpose
Advances in technology have given rise to an increased demand by small businesses for personalised e-government services. Given the importance of small businesses to the Australian economy, it is vital to deliver small business-centric services that offer potential to generate value. To do that effectively, government departments need to understand factors that affect small business. The purpose of this study is to explore how preferences for personalised services and the use of intermediaries affect small business participation behaviour and, in turn, stimulate positive outcomes that are of interest to the government.
Design/methodology/approach
This study draws on secondary data from a survey of 800 Australian small businesses about the digital services offered by a large government department. Structural equation modelling was used to empirically test the model.
Findings
The findings demonstrate that whilst preference for personalisation has a positive relationship with participation behaviour, reliance on an intermediary does not. While such behaviour fosters emotional connection and perceptions of partner quality, the results of this study show no significant impact on satisfaction.
Originality/value
This study advances knowledge about how small businesses can gain value from personalised support services. Importantly, it focuses on participation behaviour and small business – both of which are largely absent from existing studies. The findings can assist government departments to design personalised services that are valued by small businesses.
