Do special issues offer something special? An overview of research trends in Telecommunications Policy special issues

This study explores the value of special issues by analyzing the characteristics of special issues of Telecommunications Policy (TP). Specifically, this study examines the status of special issue publications, the characteristics of their articles compared with those of general issues, and the factors affecting article citations. For the analysis, all information on TP articles published from 1976 to 2018 was collected from the Scopus database. A comparative analysis as well as a negative binomial regression were conducted on papers published after 1994, when the first special issue was published. The results show that special issues are distinguished from general issues by various characteristics, such as multinational author collaboration, number of references, keywords, and funding. While general issue papers are more frequently cited in academia, special issue papers show better performance in terms of online captures and social media sharing. Moreover, the smaller number of variables affects the frequency of citations in the case of special issues, revealing that content and format are more influential than author factors.     

Economic development,food demand and the consequences for agricultural resource requirements: an application to Indonesia

We analyse food demand patterns of Indonesian households from a resource intensity perspective and quantify the impact of changed demand patterns on the use of three major resource inputs: fossil fuel; land; and water in agricultural production. Using Indonesian Family Life Survey data, 13 major food items (which constitute 70 per cent of food expenditure) are categorised into low, moderate and high resource intensity, and income elasticity and Engel curves are estimated for the period from 1997 to 2007. Our results show that income growth in Indonesia is associated with demand patterns that are more resource intensive. By 2007, per capita requirements of fossil fuel, land and water increased by 42.7 per cent (3.13 MJ), 44.9 per cent (1.24 m²) and 50.4 per cent (2.1 kL), respectively, relative to 1997. The results imply that, at least for Indonesia, changed food demand patterns resulting from economic development will increase the demand for natural resources substantially.     

Eco-labels and product longevity: The case of whitefish in UK grocery retailing

In recent years, eco-labeling has become an increasingly used tool to signal sustainable sourcing of (sea-) food. While the literature has focused on price premiums associated with the labels, it is noted in this paper that eco-labels can also contribute to profitability by reducing cost, e.g. through longer product lifespans. Hence, eco-labels can be beneficial in a supply chain even without a price premium. This study applies duration analysis to explore whether two eco-labels (the MSC label of the Marine Stewardship Council and a line-caught label) influence product longevity of whitefish products in eight different grocery retailers in the UK. The results show that MSC labeled products have a 64.7% lower risk of being withdrawn from the shelves compared to non-MSC products, while products with the line-caught label have a 32.8% lower risk of being withdrawn than products without this label. The results also indicate that the influence of the eco-labels on product longevity vary considerably between the retailers.     

Status of brands in children’s consumption: What letters to Santa posted on La Poste website tell us

The purpose of the research is to identify different consumption styles based on a large collection of letters to Santa written by some children and/or their families and submitted to the French Post website (La Poste). One of our main interests focuses on the presence and weight of brands and licenses in children’s wish lists. We have had access to all the anonymous posts sent to Santa Claus through La Poste’s website during the 2013 and 2014 Christmas holidays. We analyzed the nature of the wish lists as shown in the 43,000‐post database using several textual data analysis techniques. Extensive heterogeneity was found among children’s and families’ postures regarding that specific ritual. The different types of emails reflect the meaning families associate with Christmas time but also their different consumption styles or attitudes toward consumption: reasoned, educational, hedonistic, or materialistic, for example. When focusing on brands and licenses, we can also observe significant differences in the way families and children include them in their consumption decisions. Brands could have a very different weight in Christmas wish lists and their natures reflect different value transmission modes. The French market for Christmas children brands is rather stable and focuses on a few top leading global brands such as Playmobil, Barbie, or Lego. At least one of the ten leading brands is mentioned in half of evaluated Christmas wish lists. The analysis confirms that brands are very clearly gendered and associated with the children’s ages. Peak time for brand desire is alleged to be reached between the age of 7 and 9. To our knowledge, our research is the first to analyze a large sample of spontaneous data to capture children’s consumption styles and attitudes toward brands. Because of our classification, a first typology of parental consumption styles has also been identified.     

Multiple job holding as a strategy for skills development

This study investigated the training effect of multiple job holding on the activity of main jobs. First, we developed a dual-labor supply model by adding the training effect of working second jobs. The theory showed that workers with unconstrained hours hold second jobs when they develop skills via the experience of second jobs. To verify the hypotheses from the theoretical model, the causal relationship between holding a second job and the wage rate of a main job was estimated using the Keio Household Panel Survey. Difference generalized method of moments was adopted to remove time-invariant individual effects and endogenous bias. Moreover, the estimations showed heterogeneity of main jobs in terms of length of working hours, tasks, and job turnover. Full-time workers engaged in intelligent tasks and those who did not change their jobs secured training effects from second jobs but only when the comparison group was the workers allowed to hold second jobs by their employers. It was presumed that employers paid to restrict employees’ activities. On the contrary, part-time workers engaged in physical tasks were exhausted by second jobs, which decreased the wage rate of their main jobs.     

The determinants of austerity in the European Union 2010–16

This paper aims at decteting what drove the adoption of austerity policies over the period 2010–16 in a panel of 28 European countries. Austerity is identified by year increases in the ratio between the structural primary balance and potential GDP. By means of principal component factor analysis we select the aggregate factors that might affect austerity, namely (i) fiscal consolidation (correction of high deficits and debts), (ii) market discipline (high sovereign spreads, low ratings), (iii) rule-based fiscal discipline (compliance with the Eurozone rules), and macroeconomic stabilisation (consideration for the cyclical position of the economy). Then we estimate a dynamic panel model with the system-GMM method. Results show that the most important contributions to austerity are provided by the market discipline and fiscal consolidation factors together with Excessive Deficit Procedures, with no significant role played by concomitant macroeconomic conditions. Overall, governments complied with orthodox fiscal principles and rules.     

ALICE: Composite leading indicators for euro area inflation cycles

This paper develops Area-wide Leading Inflation CyclE (ALICE) indicators with the aim to provide early signals for turning points in the euro area headline and core inflation cycles. The headline (core) ALICE leads the reference cycle by three (four) months and the lead times extend to five (nine) months based on longer-leading series. Both ALICE indicators signalled turning points in the inflation cycles ex post and also performed well in a simulated real-time exercise. Moreover, in particular the headline ALICE also appeared to be useful for quantitative forecasting of the direction and level of inflation.     

The socio-economic determinants of COVID-19: A spatial analysis of German county level data

The study explores the association of socioeconomic, demographic, and health-related variables at the regional level with COVID-19 related cases and deaths in Germany during the so-called first wave through mid-June 2020. Multivariate spatial models include the 401 counties in Germany to account for regional interrelations and possible spillover effects. The case and death numbers are, for example, significantly positively associated with early cases from the beginning of the epidemic, the average age, the population density and the share of people employed in elderly care. By contrast, they are significantly negatively associated with the share of schoolchildren and children in day care as well as physician density. In addition, significant spillover effects on the case numbers of neighbouring regions were identified for certain variables, with a different sign than the overall effects, giving rise to further future analyses of the regional mechanisms of action of COVID-19 infection. The results complement the knowledge about COVID-19 infection beyond the clinical risk factors discussed so far by a socio-economic perspective at the ecological level.

产品差异与技术差距影响研发溢出的理论探讨

在传统研发溢出效应假设基础上，通过技术差距将溢出效应与产品差异有机联系起来，并通过构建双寡头企业两阶段博弈模型对研发卡特尔、生产卡特尔、完全合作等不同形式合作联盟的均衡水平和福利变化进行分析比较。研究证实：当企业间技术差距较小时，完全合作或研发卡特尔能有效提高企业利润和社会福利；而当技术差距较大时，研发阶段的合作不仅无法激励企业进行研发投入，还会抑制企业创新的积极性。此外，与完全合作相比，局部合作具有更强的稳定性和可持续性，尤其是在产品差异程度较大的情况下，研发卡特尔最为稳定。
