Much policy interest in sanitation and hygiene promotion focuses on changing behavior and increasing demand for these goods. Yet the effectiveness of large-scale interventions has been mixed, in large part because of the difficulty of changing attitudes on deeply rooted behaviors. This study tests whether an experiential learning exercise structured around an experimental game can be used to shift preferences around sanitation and hygiene. A minimum coordination game is adapted to the sanitation and hygiene setting by linking game choices to real-world investment decisions and payoffs in terms of health and status. Individuals from 20 villages in rural Tamil Nadu were randomly assigned to one of three groups: one that played a game in which communication between rounds was allowed, another that played a game in which communication was prohibited, and a control group that only completed a survey. Based on a comparison of survey responses across treatment arms, the game improved stated preferences in relation to sanitation and hygiene. This effect was larger when communication was allowed, and men responded on average more strongly than women across both versions of the game. These results suggest that experimental games can be a valuable tool not only for the study of decision making but for improving participants’ knowledge and pro-sanitation preferences.

In our unprecedentedly networked world, games have come to occupy an important space in many of our everyday lives. Digital games alone engage an estimated 2.5 billion people worldwide as of 2020, and other forms of gaming, such as board games, role playing, escape rooms, and puzzles, command an ever-expanding audience. At the same time, “gamification”—the application of game mechanics to traditionally nongame spheres, such as personal health and fitness, shopping, habit tracking, and more—has imposed unprecedented levels of competition, repetition, and quantification on daily life. Drawing from his own experience as a game designer, Patrick Jagoda argues that games need not be synonymous with gamification. He studies experimental games that intervene in the neoliberal project from the inside out, examining a broad variety of mainstream and independent games, including StarCraft, Candy Crush Saga, Stardew Valley, Dys4ia, Braid, and Undertale. Beyond a diagnosis of gamification, Jagoda imagines ways that games can be experimental—not only in the sense of problem solving, but also the more nuanced notion of problem making that embraces the complexities of our digital present. The result is a game-changing book on the sociopolitical potential of this form of mass entertainment.

The aim of this Handbook is twofold: to educate and to inspire. It is meant for researchers and graduate students who are interested in taking a data-based and behavioral approach to the study of game theory. Educators and students of economics will find the Handbook useful as a companion book to conventional upper-level game theory textbooks, enabling them to compare and contrast actual behavior with theoretical predictions. Researchers and non-specialists will find valuable examples of laboratory and field experiments that test game theoretic propositions and suggest new ways of modeling strategic behavior. Chapters are organized into several sections; each section concludes with an inspirational chapter, offering suggestions on new directions and cutting-edge topics of research in experimental game theory.

Increasing numbers of development agencies and individual projects espouse objectives of women’s empowerment, yet there has been little systematic work on mechanisms by which interventions can enhance women’s empowerment. This gap exists because of the lack of consensus on indicators as well as the lack of attention paid to measuring the effects of different types of interventions on empowerment. This paper identifies the types of strategies employed by 13 agricultural development projects within the International Food Policy Research Institute’s Gender, Agriculture, and Assets Project Phase 2 (GAAP2) that have explicit objectives of empowering women. We distinguish between reach, benefit, and empowerment as objectives of agricultural development projects. Simply including women does not necessarily benefit them, and even activities that benefit do not necessarily empower. To identify strategies to empower women, we build on the domains included in the Women’s Empowerment in Agriculture Index (WEAI) and are working with the GAAP2 portfolio of projects to develop an empowerment metric that is applicable in the project setting (a project-level WEAI, or pro-WEAI). We have identified the following potential domains to be included in pro-WEAI: input into production decision making, control over resources, control over income, leadership, time, physical mobility, intrahousehold relationships, individual empowerment, reduction in gender-based violence, and decision making on nutrition. The GAAP2 projects address these domains through a wide variety of activities that can be grouped into four main types: (1) direct and indirect provision of goods and services; (2) forming or strengthening groups, organizations, or platforms and networks that involve women; (3) strengthening knowledge and capacity through agricultural extension, business and finance training, nutrition behavior change communication, and other training; and (4) changing gender norms through one-way awareness raising or two-way community conversations about gender issues and their implications. In general, projects with activities in more activity areas target more domains of empowerment, and most projects target a core set of six empowerment domains. With the exception of intrahousehold relationships, which is always targeted by activities designed to influence gender norms, projects target domains with different types of activities or combinations of activities. This setup suggests that there may be no one-to-one link between a specific activity and empowerment benefits, and that implementation modalities will determine whether and how an activity contributes to women’s empowerment. The effectiveness of these project strategies will be assessed using both quantitative and qualitative methods throughout the GAAP2 research project.

Since the individuals are not just stimulus-response machines but more complex beings that think and are simultaneously conscious of their thought, re?exivity is potentially involved in all human acts of cognition and in all conceptualizations. On this basis, each human discourse can be characterized as a way of thought f- mulation and therefore, reveals a self-referring nature. On this level of re?exivity, the individual thought shapes beliefs and mental representations which give life to mental models and strive to predict future events and developments to support the individuals in their decision-making. Such mental models are re?ected by the - dividuals themselves and on the situation they are confronted with. According to the result of this recursive application, the individuals will then decide which model they want to refer to, or in other words, which model they want to absorb. Similarly, the individuals can make use of social theories and predictions which can therefore yield recursive effects and interfere with the phenomena they aim to depict. Revealed theories, if accepted, may in?uence the behaviour or the agents they focus on, either in the sense of validation of the theoretical content or in that of its rejection.

While the field of economics makes sharp distinctions and produces precise theory, the work of experimental economics sometimes appears blurred and may produce uncertain results. The contributors to this volume have provided brief notes describing specific experimental results.
