Growth in the age of automation: Foundations of a theoretical framework

The replacement of humans by machines in the development of a wide array of productive tasks is changing the economic landscape. Mutations on the structure of employment, widening income gaps, and uncertain effects over growth are some of the worries currently in the mind of economists. This article develops the foundations of a neoclassical growth model that puts into perspective the impact of automation over the aggregate economy. In particular, efficiency gains propelled by the current wave of innovation are confronted with the associated loss of jobs and with the potential social unrest and anxiety that the substitution of labor by robots brings. The strength of each effect determines transition paths and steady‐state results.

A life cycle model of industrial heritage development

The milieus of industrial complexes and their potential reuse for tourism have gained prominence worldwide. This paper proposes a life cycle model of industrial heritage development, consisting of territorialization, deterritorialization, and reterritorialization to illustrate the intricate interplay of identity, landscape and socio-spatial changes in the LX Factory in Lisbon, Portugal. In the stage of territorialization, postindustrial sites are identified as an important heritage source. Deterritorialization denotes the stage in which forces of tourism infuse new meanings into these sites. Reterritorialization indicates a burgeoning phenomenon of repurposing the industrial landscape for the use of creative industries and consequently generating a different territorial identity.     

Automated inference of product attributes and their importance from user-generated content: Can we replace traditional market research?

User-generated content, particularly online product reviews by customers, provide marketers with rich data of customer evaluations of product attributes. This study proposes, benchmarks, and validates a new approach for inferring attribute-level evaluations from user-generated content. Moreover, little is known about whether and when insights from product reviews gained in such a way are consistent with traditional research methods, such as conjoint analysis and satisfaction driver analysis. To provide first insights into this question, the authors apply their approach to a dataset with almost one million product reviews from 52 product categories and run conjoint and satisfaction driver analyses for these categories. Results indicate that the consistency between methods largely varies across product categories. Initial exploratory analyses suggest that consistency might be higher for categories characterized by low experience qualities, high hedonic value, and high customer willingness to post online reviews—but further work will be necessary to validate these findings.     

The macroeconomic impact of automation: Applications to elderly care

When automation technology can both help a firm's production and be widely used in the provision of long-term care for the elderly, developments in automation can potentially help alleviate the situation of a declining birthrate in an aging society and increase production and household welfare. In addition, this paper obtains results consistent with the real-world situation in which population aging and a declining birthrate arise simultaneously. Considering the case where automation technology is developed by firms does not change the main findings. Therefore, the government should encourage people to engage in the development of automation.     

The influence of customer experience with automated games and social interaction on customer engagement and loyalty in casinos

Drawing on experiential marketing theory, This study examines the relationship between casino customers’ experience with automated games and their engagement and loyalty responses to casinos. Social interaction as a proxy of visiting motivation is modelled as a moderator in the relationship. Customer behaviours include word-of-mouth, visiting frequency, and average spending. The study focuses on Australian land-based casino members with automated game experience. The results show that customer experience with some features of automated games had a positive and significant impact on customer engagement with the casino, which led to positive loyalty. Automated game experience also had an indirect effect on customer loyalty. Social interaction exhibited a significant moderating effect on the relationship between customer engagement and visiting frequency. Discussion and implications of these findings for the literature and practitioners conclude the paper.     

Labor‐eliminating technical change in a developing economy

Developing countries face significant challenges arising from automation. While the trade theory literature has tended to focus on factor‐neutral and factor‐augmenting technical change, automation processes suggest another form of technical change is relevant: factor‐eliminating. We explore the impact of a labor‐eliminating technical change in the context of a small developing economy. Unlike labor‐augmenting technical changes, labor‐eliminating technical changes are not necessarily cost‐reducing, and thus will not necessarily be adopted. A manufacturing wage held artificially higher than at the market‐clearing level, as in the Harris–Todaro framework, increases the incentive to automate. We establish the conditions under which firms will adopt a labor‐eliminating technology, and describe the resulting changes in equilibrium outcomes. Under plausible circumstances, automation can actually lower output, and may raise both the rate and level of unemployment. Immiserizing growth becomes a possibility, and can be tied directly to the underlying wage distortion.     

薄弱配电网高比例分布式光伏并网消纳规划研究

为了解决薄弱电网高比例分布式光伏难以就地消纳问题,提出储能系统和需求侧响应运行策略,建立了计划接入总量下的高比例分布式光伏双层规划模型。以光伏最大消纳为目标函数,光伏安装位置与容量为优化变量,建立上层模型;以系统净负荷峰谷差期望值最小为目标函数,各时段电价为优化变量,建立下层模型。针对光伏随机出力与负荷的时序性,利用拉丁超立方抽样技术对其进行处理。在此基础上,采用概率潮流法与细胞膜粒子群优化算法相结合的混合智能算法对模型进行求解,并以河北省某贫困县光伏扶贫村网架结构为例进行算例分析。结果表明,解决方案在实现光伏接入容量最优配置的基础上,进一步提高了薄弱配电网分布式光伏的消纳能力。双层规划模型能够在很大程度上提高再生能源的利用率,可为配电网规划提供参考。
