This article investigates the interplay between scientific and technological capabilities in regional technological diversification dynamics by looking at the contributions of academic inventors. Combining the evolutionary economic approach and the theories on regional innovation capabilities on the one hand, and the distinctive features of academic inventors and university–industry patenting on the other, we hypothesize that the participation of university-based inventors to local patenting activity positively influences the chance of regional technological diversification and mitigates the path dependency engendered by the constraining role of the technological relatedness. In addition, we hypothesize that academic inventors tend to push regional technological trajectories towards their portfolio of specializations, hence allowing a process of technological convergence. The empirical results highlight the key role of academic institutions in the development of new regional technological trajectories while contributing to the academic and policy debate on regional diversification strategies.

Agglomeration externalities are the key factor explaining the existence of cities and their size. However, while the various micro foundations of agglomeration externalities stress the importance of total factor productivity (TFP), the empirical evidence on agglomeration externalities rests on measures obtained using firm revenue or value-added as a measure of firm output: revenue-based TFP (TFP-R). This article uses data on French manufacturing firms’ revenue, quantity, and prices to estimate TFP and TFP-R and decompose the latter into various elements. Our analysis suggests that the revenue productivity advantage of denser areas is mainly driven by higher prices charged rather than differences in TFP. At the same time, firms in denser areas are able to sell higher quantities and generate higher revenues, despite higher prices. These and other results we document suggest that firms in denser areas are able to charge higher prices because they sell higher demand/quality products. In this respect, two key elements related to this capacity to sell more at higher prices are the degree of vertical differentiation and trade cost, with products characterized by higher vertical differentiation and/or lower trade costs featuring stronger patterns and driving overall results.

An increasing number of regional trade agreements contains provisions that ease access to visas among member countries, which reduces the administrative cost of crossing the border. Combining United Nations data on bilateral stocks of immigrants in the period 1990–2020 with World Bank data on the content of 279 regional trade agreements, this article presents robust evidence of a positive effect of visa provisions in regional trade agreements on bilateral migration: the presence of visa provisions in regional trade agreements increases the bilateral stock of immigrants by 5.8 per cent. This result is robust to an instrumental variable strategy addressing the endogeneity problem. The effect of the inclusion of visa provisions in regional trade agreements is particularly effective among country pairs with different income levels (such as North-South). For this type of country pairs, the presence of visa provisions in regional trade agreements increases the bilateral stock of immigrants by 12.7 per cent. Finally, the article shows that the effectiveness of visa provisions in regional trade agreements reduces with the anti-immigration sentiment of voters in the destination.

We analyze the externalities arising from a bilateral asylum policy—the list of safe origin countries—relying on a tractable model. Using self-collected monthly data, we estimate that including one origin country on the safe list of a given destination decreases asylum applications from that origin to that destination by 29 per cent. We use a counterfactual policy simulation to quantify the spillover effects occurring across origin and destination countries. Individuals from targeted origin countries move to alternative destinations. Individuals from untargeted origins divert from alternative destinations. The magnitude of the externalities depends on the size of the affected flows.

We argue that trans-local knowledge connections positively impact local epistemic inventor communities in global cities, using patent citations as an indicator of global knowledge connectivity. Patented inventions have become more concentrated in the most internationally connected global cities, increasing inter-regional inequality. We identify two dimensions of knowledge connectivity: the compatibility of connections between similar profiles of technological knowledge, and the geographical diversity of knowledge connections between differently specialized global cities. We suggest that interaction between local and international inventor epistemic communities is now a vital driver of local innovation in global cities, and interregional inequality between these and other cities.

Drawing on financial geography literature and the concept of state rescaling, this article investigates the state–finance nexus with an emphasis on state spatial reconfiguration. Through a historically and geographically informed political economic analysis, it argues that China’s state-led, market-oriented rural banking reforms are not merely the outcome of a deepening market logic within the financial administration of the rural sector. They are also crucial for state spatial reconfiguration to address uneven rural and urban development. The article calls for greater sensitivity towards relational spatiotemporality and uneven development to comprehend fully the spatiality of the state–finance nexus.

This article combines unconditional quantile regressions with difference-in-differences to study the distributive effects of a foreign buyer tax (FBT) on home prices in New South Wales (NSW). The main results reveal that the FBT reduces house prices in NSW but only among the more expensive houses located in desirable neighborhoods of Sydney and with a relatively high share of foreign-born population. We find evidence that the FBT reduces transaction volumes in the same expensive Sydney neighborhoods and immigrant enclaves where house prices are observed to decline, in support of a direct mechanism that the FBT curbs foreign demand. Additional results suggest that more expensive homes are not substituted with less expensive housing, and that some foreign buyers respond to the FBT by divesting away from NSW locations. The main policy implication is that the FBT may help deter foreign buyers from accumulating higher-priced and luxury assets, but may fail to address broader housing affordability concerns facing the local population.

Social scientists and policymakers alike have become increasingly concerned with understanding the nature, causes, and consequences of inter-regional inequality in economic living conditions. Contemporary spatial inequality is multi-faceted—it varies depending on how we define inequality, the scale at which it is measured, and which groups in the labor force are considered. Increasing economic inequality has important implications for broader social and political issues. Notably, it is difficult to account for the rise of far-right populism in industrialized countries without considering the context of growing inter-regional inequality. Important explanations for the rise in inter-regional inequality include changing patterns of worker and firm sorting processes across space, major transitions like the reorientation of the economy from manufacturing to digital technologies, and increasing global economic integration, as well as policy. Different causal explanations in turn imply a different role for place-based policy. This article introduces the context of the special issue on the nature, causes, and consequences of inter-regional inequality, focusing specifically on inequality in North America and Western Europe, and aims to identify challenges for, and spark further research on, inter-regional inequality.

This article examines the effect of formal and informal institutional settings and of the governance of inter-organizational relationships on innovation at the cluster level. The research primarily relies on quantitative methods, utilizing data obtained from a survey involving 115 firms and 12 in-depth interviews. Supplementary qualitative information from the interviews has also been incorporated into the analysis. The results support the hypothesis that innovative firms should consider not only the impact of different governance modes but also how these modes align with the existing local contexts. Failure to do so may result in firms becoming entrenched in the prevailing practices and products of a specific location.

Persistent racial inequality in socioeconomic status within urban areas has been a significant concern in both the US and European countries. Differences across racial groups in intergenerational mobility (IM) have been identified as a key source of this persistence. However, efforts to understand racial inequality in IM have rarely considered the role of urban sprawl. This article argues that urban sprawl affects differences in IM between racial groups directly and indirectly through racial segregation, racial bias, and social capital. We analyze data from 874 metropolitan counties in the US using structural equation models to test these direct and indirect effects of sprawl on racial inequality in IM. We found that urban sprawl was negatively associated with racial inequality in IM. The direct effect, which we partially attribute to higher racial disparities in social capital in more compact counties, was statistically significant. For the indirect effects, racial segregation had the largest mediating effects between urban sprawl and racial inequality in IM, followed by economic connectedness (EC) and racial bias. The net indirect effect of sprawl on racial inequality in IM was negative because negative indirect effects through racial segregation and EC outweigh positive indirect effects through racial bias. Our findings demonstrate the significant role of urban form in racial inequality in IM.
在美国和欧洲国家，城市地区社会经济地位中持续存在的种族不平等现象一直备受关注。不同种族群体之间在代际流动性（IM）方面的差异被认为是造成这种持续性的主要原因。然而，人们在努力理解代际流动中的种族不平等时，却很少考虑城市扩张的作用。本文认为，城市无计划扩展通过种族隔离、种族偏见和社会资本直接或间接地影响了种族群体间代际流动的差异。我们使用结构方程模型分析了来自美国 874 个大都市县的数据，以检验无计划扩展对种族 IM 不平等的直接和间接影响。我们发现，城市扩张与 IM 中的种族不平等呈负相关。我们将这种直接影响部分归因于在更紧凑的县城中社会资本的种族差异更大，这种直接影响在统计上是显著的。就间接效应而言，种族隔离在城市无计划扩展与 IM 中的种族不平等之间具有最大的中介效应，其次是经济联系（EC）和种族偏见。无计划扩展对 IM 中种族不平等的净间接效应是负的，因为通过种族隔离和经济联系产生的负间接效应超过了通过种族偏见产生的正间接效应。我们的研究结果表明，城市形态在 IM 的种族不平等中发挥着重要作用。
