江苏省测土配方施肥技术的经济效果评价

本文利用江苏省已推广实施测土配方施肥技术的2个项目县的农户调查数据,通过建立PMP模型,对该技术的经济效果进行了评价。研究结果表明:测土配方施肥技术对增加农户收入的效果明显;该技术的采用会使竞争性作物种植体系中各种作物的播种面积有所调整,但在种植单一作物的情况下则其播种面积不变。     

Optimal menu when agents make mistakes

This paper studies how an optimal menu chosen by a social planner depends on whether agents receive imperfect signals about their true tastes (imperfect self-knowledge) or the properties of available alternatives (imperfect information). Under imperfect self-knowledge, it is not optimal to offer fewer alternatives than the number of different tastes present in the population, unless noise is infinite (agents have no clue about their true preferences). As noise increases, the social planner offers menu items that are closer together (more similar). However, under imperfect information, as noise increases, it could be optimal to construct a menu with more distinct alternatives, restrict the number of options, or, for some finite noise, offer a single item.     

Mood management through metaverse enhancing life satisfaction

This study aims to explore a social metaverse's positive effects as mood management on consumers' life satisfaction and usage intentions. A total of 304 survey responses from active users of a popular social metaverse platform, Zepeto, were collected with help from an online survey firm. Structural equation modeling analysis was conducted using AMOS 25.0. The direct paths from social metaverse consumption as positive mood enhancement and negative mood alleviation to consumers' life satisfaction were significant, which led to greater usage intentions. Positive mood enhancement influenced usage intentions both directly and indirectly through increased life satisfaction; however, the effect of negative mood alleviation on usage intentions was fully mediated by life satisfaction. Interestingly, for the players who spend money in the social metaverse, only the path from negative mood alleviation to usage intentions mediated by life satisfaction was significant.     

Emotions and consumer behaviour: A review and research agenda

Consumers' emotions play a salient role in consumers' buying process, their consumption behaviours, and their engagement with product/service offerings, owing to which, it has gained much attention in recent years as an area of inquiry. However, literature in this field/subject is theoretically fragmented. Therefore, to enhance the conceptual understanding, this study synthesizes extant literature, using a hybrid review approach. Herein, we attempt to integrate bibliometric analysis, along with the theories, contexts, characteristics, and methodology framework, while consolidating and classifying the domain knowledge, trends, and progress/citation analysis using the bibliometric approach. In the process, we reviewed 384 conceptual and empirical articles, published during the period 1967–2021. The idea was to identify key theories, constructs, research contexts, and methods, based on which, we propose a few potential research areas. Based on our thorough analysis, these areas include (1) consumer co-creation, (2) consumer engagement, (3) service employee interactions, (4) consumer decision making, and (5) consumption experience.     

Is it time to reboot welfare economics? Overview

The contributions of economists have long included both positive explanations of how economic systems work and normative recommendations for how they could and should work better. In recent decades, economics has taken a strong empirical turn as well as having a greater appreciation of the importance of the complexities of real-world human behaviour, institutions, the strengths and failures of markets, and interlinkages with other systems, including politics, technology, culture and the environment. This shift has also brought greater relevance and pragmatism to normative economics. While this shift towards evidence and pragmatism has been welcome, it does not in itself answer the core question of what exactly constitutes ‘better’, and for whom, and how to manage inevitable conflicts and trade-offs in society. These have long been the core concerns of welfare economics. Yet, in the 1980s and 1990s, debates on welfare economics seemed to have become marginalised. The articles in this Fiscal Studies symposium engage with the question of how to revive normative questions as a central issue in economic scholarship.
