Marshallian labor market pooling: evidence from Italy

This paper employs a unique Italian data source to take a comprehensive approach to labor market pooling. It jointly considers many different aspects of the agglomeration labor market relationship, including turnover, learning, matching, and hold up. It also considers labor market pooling from the perspective of both workers and firms and across a range of industries. The paper reports a general positive relationship of turnover to local population density, which is consistent with theories of agglomeration and uncertainty. The paper also finds evidence of onthejob learning that is consistent with theories of labor pooling, labor poaching, and hold up. In addition, the paper provides evidence consistent with agglomeration improving job matches. However, the labor market pooling gains that we measure are small in magnitude and seem unlikely to account for a substantial share of the agglomeration benefits accruing to worker and firms

The health benefits of autonomous vehicles: public awareness and receptivity in Australia

Objectives: The substantial public health benefits of autonomous vehicles will be optimised once all vehicles operate in autonomous mode. This form of disruptive technology will need to be widely accepted by the community to facilitate the regulatory and behavioural adjustments required to achieve rapid adoption. The aim of this study was to assess: i) receptiveness to autonomous vehicles; ii) the salience of various health benefits (e.g. crash prevention, emission reduction, driving stress reduction, cyclist safety, increased mobility for those unable to drive); and iii) prompted awareness of these health benefits. Methods: Quantitative and qualitative data were generated via a national online survey of a broad range of Australians aged 16 years and over (n=1,624). Results: There were neutral levels of receptiveness and very low salience of health benefits, but more substantial levels of prompted awareness of positive health outcomes. Conclusions: These results suggest that the public may be interested in information relating to the individual and societal health benefits of autonomous vehicles, which in turn may increase overall support for this innovation. Implications for public health: Australians are likely to be receptive to autonomous vehicles when provided with information relating to their public health benefits

External economies as a mechanism of agglomeration in EU manufacturing

International audienceProductive externalities are significant determinants of agglomeration, not deeply studied at the industry and international level. We analyse the impact on productivity growth of technological externalities, both inter- and intraindustry, national or international, at the industry level for the European Union (EU) countries and the period 1995-2002. The results confirm the advisability of considering international externalities when countries are takes as regions, whose omission underestimates national spillovers. Together with national endowments and a central geographical position, the growth of productivity is encouraged by national and international specialization as a general result; moreover, it is fuelled by stronger interindustry spillovers and productive diversification, a result more evident for high technology industries, while lower technology industries are more sensitive to the omission of international externalities. Economic integration seems to be relevant, because supranational regions with less friction for goods and factor movements are more likely to take advantage of external economies as a mechanism of productivity growth and agglomeration

Vitamin D and Calcium Supplementation Accelerates Randall's Plaque Formation in a Murine Model

Most kidney stones are made of calcium oxalate crystals. Randall\u27s plaque, an apatite deposit at the tip of the renal papilla, is considered to at the origin of these stones. Hypercalciuria may promote Randall\u27s plaque formation and growth. We analyzed whether long-term exposure of Abcc6 mice (a murine model of Randall\u27s plaque) to vitamin D supplementation, with or without a calcium-rich diet, would accelerate the formation of Randall\u27s plaque. Eight groups of mice (including Abcc6 and wild type) received vitamin D alone (100,000 UI/kg every 2 weeks), a calcium-enriched diet alone (calcium gluconate 2 g/L in drinking water), both vitamin D supplementation and a calcium-rich diet, or a standard diet (controls) for 6 months. Kidney calcifications were assessed by 3-dimensional microcomputed tomography, μ-Fourier transform infrared spectroscopy, field emission-scanning electron microscopy, transmission electron microscopy, and Yasue staining. At 6 months, Abcc6 mice exposed to vitamin D and calcium supplementation developed massive Randall\u27s plaque when compared with control Abcc6 mice (P < 0.01). Wild-type animals did not develop significant calcifications when exposed to vitamin D. Combined administration of vitamin D and calcium significantly accelerates Randall\u27s plaque formation in a murine model. This original model raises concerns about the cumulative risk of vitamin D supplementation and calcium intakes in Randall\u27s plaque formation

Government institutions and the dynamics of urban growth in China

Economic growth in China in recent decades has largely rested on the dynamism of its cities. High economic growth has coincided with measures aimed at improving the efficiency of local governments and with a mounting political drive to curb corruption. Yet the connection between government institutions and urban growth in China remains poorly understood. This paper is the first to look into the link between government efficiency and corruption, on the one hand, and urban growth in China, on the other hand and to assess what is the role of institutions relative to more traditional factors for economic growth in Chinese cities. Using panel data for 283 cities over the period between 2003 and 2014, the results show that the urban growth in China is a consequence of a combination of favorable human capital, innovation, density, local conditions, foreign direct investment, and city-level government institutions. Both government quality—especially for those cities with the best governments—and the fight against corruption at the city level have a direct effect on urban growth. Measures to tackle corruption at the provincial level matter in a more indirect way, by raising or lowering the returns of other growth-inducing factors

Cultural and creative industries and regional diversification:Does size matter?

This paper aims at analysing how the presence of workers employed in cultural and creative industries (CCIs) is related to regional specialized diversification. From a theoretical perspective, CCIs drive economic development and local innovative capacity by facilitating processes of cross-fertilization of ideas. This study estimates an entry model analysing the ability of Italian provinces to successfully create new sectoral specializations. The results indicate that the relationship between the share of employees in CCIs and the probability of creating new sectoral specializations is non-linear, highlighting the need for CCIs-led policies to achieve a certain level of critical mass to be successful

Heterogeneous Agglomeration

Many prior treatments of agglomeration explicitly or implicitly assume that all industries agglomerate for the same reasons. This paper uses U.K. establishment-level coagglomeration data to document substantial heterogeneity across industries in the microfoundations of agglomeration economies. It finds robust evidence of organizational and adaptive agglomeration forces as discussed by Chinitz (1961), Vernon (1960), and Jacobs (1969). These forces interact with the traditional Marshallian (1890) factors of input sharing, labor pooling, and knowledge spillovers, establishing a previously unrecognized complementarity between the approaches of Marshall and Jacobs, as well as others, to the analysis of agglomeration

Developing intermediate cities

Intermediate cities have experienced economic dynamism in recent years, but, with the focus firmly on large metropoles and sprawling megacities, the development potential of intermediate cities has stayed out of the limelight. This paper upholds the relevance and potential of intermediate cities, arguing that they can play as important a role – if not a more important one – than the large metropoles that, until now, have been the focus of attention. Intermediate cities hold considerable advantages, in particular for poverty reduction and as more efficient ecosystems to live and work. Untapping the potential of intermediate cities requires, however, more territorially balanced, place-sensitive strategies
