This paper examines the contingent nature of agglomeration economies. Existing empirical evidence that compact cities are more productive is mostly from countries and regions with highly productive service sectors, such as the USA or Europe. We hypothesise that this relationship will differ in countries where land-intensive manufacturing activities are more productive than services. In this paper, we test this hypothesis using data from the 100 largest cities in Mexico in 1990, 2000 and 2010. Under a number of specifications, we find that the most common measures of urban compactness are, in fact, negatively associated with economic productivity. This holds even when instrumenting urban spatial structure with the underlying geology of urban areas. The findings suggest a need for greater attention to national economic structure in the study of agglomeration economies, and that policy agendas focused on compact urbanisation take account of the needs of the manufacturing sector.

The Impact

Since 2001 the Mexican manufacturing sector has experienced a reduced rate of growth. This study estimates the impact of US and Chinese industrial activity on the demand for labor in the sector. A time series cointegration model is developed using data on industrial activity, Chinese exports, wages and the peso: dollar exchange rate. The results show that exports from China to the USA and manufacturing wages have both affected labor demand negatively, while factors such as US industrial production and the exchange rate encourage manufacturing activity.

Urban Activity

Estimating the capabilities, or inputs of production, that drive and constrain the economic development of urban areas has remained a challenging goal. We posit that capabilities are instantiated in the complexity and sophistication of urban activities, the know-how of individual workers, and the city-wide collective know-how. We derive a model that indicates how the value of these three quantities can be inferred from the probability that an individual in a city is employed in a given urban activity. We illustrate how to estimate empirically these variables using data on employment across industries and metropolitan statistical areas in the USA. We then show how the functional form of the probability function derived from our theory is statistically superior when compared with competing alternative models, and that it explains well-known results in the urban scaling and economic complexity literature. Finally, we show how the quantities are associated with metrics of economic performance, suggesting our theory can provide testable implications for why some cities are more prosperous than others.

Using Data

The purpose of this study is to investigate the determinants of household income following the loss of land owing to urban expansion in central Vietnam. Using data mainly from household surveys in the peri-urban areas of Hue city, the regression model indicates that demographic factors and livelihood strategy choices have important impacts on household income; financial compensation and support packages do not appear to be strong determinants of household income after the loss of land. This implies a failure of the current compensation programmes in the process of compulsory land acquisition, because the government believes that compensation packages make important contributions to livelihood reconstruction. This study suggests that investing in education and skill training for household members affected by land loss as well as assistance in converting compensation money into an adequate livelihood should be taken into consideration.

Using Data

Data Envelopment Analysis (DEA) is an established powerful mathematical programming technique, which has been employed quite extensively for assessing the efficiency/performance of various physical or virtual and simple or complex production systems, as well as of consumer and industrial products and technologies. The purpose of the present study is to investigate whether DEA may be employed for evaluating the technical efficiency/performance of 3D printers, an advanced manufacturing technology of increasing importance for the manufacturing sector. For this purpose, a representative sample of 3D printers based on Fused Deposition Modeling technology is examined. The technical factors/parameters of 3D printers, which are incorporated in the DEA, are investigated and discussed in detail. DEA evaluation results compare favorably with relevant benchmarks from experts, indicating that the suggested DEA technique in conjunction with technical and expert evaluation could be employed for evaluating the performance of a highly technological system, such as the 3D printer.

Abstract Background Concern about the health impacts of e-cigarette use is growing; however, limited research exists regarding potential long-term health effects of this behavior. This study explored the relationship between e-cigarette use and COPD in a sample of US adults. Methods A secondary data analysis using data from the 2018 Behavioral Risk Factor Surveillance Survey in the USA was computed to examine associations between e-cigarette use and COPD controlling for conventional cigarette smoking status, past month leisure physical activity and demographic characteristics including age, sex, education, race, marital status and body mass index. Results Significant associations between e-cigarette use and COPD among former combustible cigarette smokers and those who reported never using combustible cigarettes were found. Compared with never e-cigarette users, the odds of having COPD were significantly greater for daily e-cigarette users (OR = 1.53; 95% CI: 1.11–2.03), occasional users (OR = 1.43, 95% CI: 1.13–1.80) and former users (OR = 1.46 95% CI: 1.28–1.67). Conclusions Findings from this study indicate a potential link between e-cigarette use and COPD. Further research to explore the potential effects of e-cigarette on COPD is recommended.

AbstractMulti-stakeholder initiatives (MSIs) have emerged as a leading institutional approach for advancing sustainability globally. This paper examines three prominent MSIs that have developed sustainability metrics and a standard for US agriculture: Field to Market, the Stewardship Index for Specialty Crops and the National Sustainable Agricultural Standard Initiative. Using data from interviews and content analysis of initiative reports, two sets of analyses are presented. First, building on Paul Thompson's tri-partite theorization of sustainability, how each initiative is conceptualizing agricultural sustainability is analyzed. We find that two contrasting visions of sustainable agriculture for the USA have emerged from the three MSIs. One vision is a resource sufficiency approach focused on eco-efficiencies and the other vision is a functional integrity approach that emphasizes the maintenance of resilient agricultural and ecological systems. Second, we examine the governance practices of the MSIs to explain why such divergent conceptualizations of sustainability have been mapped out. We find that far from being a neutral forum, the internal dynamics of MSIs often reflect and reproduce existing power relationships among stakeholders. In concluding, we suggest that incremental improvements in sustainability can be achieved using MSIs, but more transformative changes may require other forms of governance.

The negative wealth–fertility relationship brought about by market integration remains a puzzle to classic evolutionary models. Evolutionary ecologists have argued that this phenomenon results from both stronger trade-offs between reproductive and socioeconomic success in the highest social classes and the comparison of groups rather than individuals. Indeed, studies in contemporary low fertility settings have typically used aggregated samples that may mask positive wealth–fertility relationships. Furthermore, while much evidence attests to trade-offs between reproductive and socioeconomic success, few studies have explicitly tested the idea that such constraints are intensified by market integration. Using data from Mongolia, a post-socialist nation that underwent mass privatization, we examine wealth–fertility relationships over time and across a rural–urban gradient. Among post-reproductive women, reproductive fitness is the lowest in urban areas, but increases with wealth in all regions. After liberalization, a demographic–economic paradox emerges in urban areas: while educational attainment negatively impacts female fertility in all regions, education uniquely provides socioeconomic benefits in urban contexts. As market integration progresses, socio-economic returns to education increase and women who limit their reproduction to pursue education get wealthier. The results support the view that selection favoured mechanisms that respond to opportunities for status enhancement rather than fertility maximization.

The Impact

Purpose There is a perception that non-religious consumers are less ethical than religious consumers. Studies found prejudices against atheists around the world and assumed that those who committed unethical behavior were more likely to be atheists. Hence, first, the purpose of this study is to investigate the effect of consumers’ intrinsic religiosity, extrinsic religiosity and atheism on consumers’ ethical beliefs. Second, this study attempts to segment consumers and identify differences between these segments. Design/methodology/approach Using data from 235 study participants in the USA and 531 in Vietnam. Subsequently, a two-step cluster approach was used to identify segments within these samples. Findings The study results show consumers’ intrinsic religiosity negatively influences all consumers’ unethical beliefs. Similarly, atheism also negatively influences all consumers’ unethical beliefs. This study also complements other studies exploring consumer ethics in developing countries. In addition, the segmentation analysis produced unique segments. The results from both samples (USA and Vietnam) indicated that non-religious consumers are less likely to accept various unethical behaviors compared to religious consumers. Religious consumers are not necessarily more ethical and atheism consumers are not necessarily less ethical. In the end, are implications for business ethics, religious and non-religious leaders on how to view the impact of beliefs on consumer ethical behaviors. Originality/value This is one of the first few studies investigating the impact of atheism on consumer ethics. The results of this study further extend the knowledge of study in consumer ethics by comparing consumers’ religiosity and atheism.

Very High

Very high resolution (VHR) satellite imagery from Google Earth and Microsoft Bing Maps is increasingly being used in a variety of applications from computer sciences to arts and humanities. In the field of remote sensing, one use of this imagery is to create reference data sets through visual interpretation, e.g., to complement existing training data or to aid in the validation of land-cover products. Through new applications such as Collect Earth, this imagery is also being used for monitoring purposes in the form of statistical surveys obtained through visual interpretation. However, little is known about where VHR satellite imagery exists globally or the dates of the imagery. Here we present a global overview of the spatial and temporal distribution of VHR satellite imagery in Google Earth and Microsoft Bing Maps. The results show an uneven availability globally, with biases in certain areas such as the USA, Europe and India, and with clear discontinuities at political borders. We also show that the availability of VHR imagery is currently not adequate for monitoring protected areas and deforestation, but is better suited for monitoring changes in cropland or urban areas using visual interpretation.

Doctoral Student Socialization

PurposeThe purpose of this paper is to explore the role scholarly conferences play in professional socialization of doctoral students.Design/methodology/approachUsing data from 20 interviews on conference experiences of student attendees of a North American conference in social sciences, as well as on the conference experiences of students from various disciplines at a private research intensive university in the USA, the authors explored how research identity of doctoral students change over time as result of participation in conferences, how the process of socialization is shaped by advisers and peers and how the experiences vary depending on the characteristics of the participants.FindingsThe authors found that conferences play an important role in socialization, and the effect from conference attendance increases with the number of conferences attended. The study also showed that students undergo several stages in the process of their socialization, throughout which they develop greater agency and independence as scholars, as well as a more positive image of themselves as researchers, and become more strategic in their behavior. The results also point to the key role of adviser and peers in the process of socialization, whereby the former can provide direction and orientation, while the latter may offer support and opportunities for mutual learning or future collaboration. The authors also found a notable difference in the support provided by advisers between teaching and research-oriented universities.Originality/valueThe paper applies doctoral student socialization theory to the analysis of informal doctoral experiences outside the program of study.
