Abstract
We present the first demonstration of the influence of a quality rivalry on location choices under spatial price discrimination. The rivalry is shown to generate the socially efficient quality but to push locations inefficiently close together, a result not found under Hotelling pricing. We apply this new equilibrium to the anti-trust policy issue of collusion showing that introducing the quality rivalry reduces the likelihood of collusion.

China and Taiwan, as well as the US, have failed to adapt new practices in response to the paradigmatic changes in the sources and nature of the China-Taiwan conflict. Reflecting the tremendous political and social changes in Taiwan, China, and the world that have occurred during the past 10-15 years, the most prominent source of the China-Taiwan conflict has shifted from power to identity. This article discusses the change of social identity in Taiwan and the re-emergence of nativistic nationalism in the PRC identity. The authors suggest that policymakers on all three sides could begin to re-think the Taiwan issue by taking advantage of the ideas and methods pioneered by experts in the rapidly growing field of conflict analysis and resolution. In this article, the authors apply concepts related to identity used by practitioners in the field of conflict resolution to look at the deeper cultural issues of identity and suggest some more appropriate methods for intervention and resolution of this deeply rooted conflict.

AbstractGentrification‐induced displacement entails a process of disrupting the inhabitants' ties to their localities. This study investigates the evolving neighbourhood attachment of resettled residents after gentrification‐induced displacement in the Chinese context. Using mixed methods, it comprehensively examines the behavioural and cognitive–affective changes in neighbourhood attachment of two groups of work‐unit residents in Chengdu, China—those resettled in situ and those out‐migrated due to gentrification. The study reveals mixed changes in the multidimensional neighbourhood attachment for both groups postdisplacement. Re‐establishing this attachment hinges upon an intricate interplay between residents' adaptive behaviours and their cognitive and emotional connections with the new places. While residents who remain within the gentrified area possess potential for rebuilding neighbourhood bonds, those relocated away from the original site experience feelings of placelessness. Furthermore, the physical environment influences residents' capacity to reconstruct functional dependencies on new surroundings, while the social environment is pivotal in shaping individuals' sense of belonging and identity postdisplacement. Finally, multiscalar contextual factors at the individual, neighbourhood, and city levels are fundamental to varying postdisplacement experiences across regions and social groups. This study enhances comprehension of the intricacies and diversities in postdisplacement experiences among resettled residents across various contexts.

Abstract
By spurring trade, the level of income and consumption and production increase, which consequently causes a more polluted environment. As global economic integration escalates, the possibility of contention becomes more translucent. The foundation of this article is based on the Ricardian model regarding consumption and production pollution function in six scenarios depending on Autarky or trade situation. There is also a difference in the relative labour size of countries. Also, pollution tightness can clarify whether there are any concerns about climate change regarding the production pollution function and consumption pollution function. The theoretical approach proves that unemployment does not occur when we have no concerns about climate change and this tightness of pollution would not impact the level of production and consumption. The emission intensity, relative labour size and tightness of pollution targets are the key elements discussed in both Autarky and trade. The critical point about trade is that it enters specialization, and the home country only produces good 1 and the foreign country only produces good 2. The main finding of this paper, based on a simple theoretical approach, is about the impact of one unit change in relative labour size regarding pollution tightness with respect to the labour force of both home and foreign countries is provided at the end.

This article investigates whether residents have been able to regain their sense of belonging and neighbourliness after being resettled in urban China and what factors have prevented or enabled them to do so. There is a growing body of work examining the post-resettlement community relations of residents. However, this process of community rebuilding is mostly understood as resident-led and little is known about the role and influence of state actions such as state-led community building and changing resettlement policies. Our study addresses this gap by drawing on the case of Hesha Hangcheng which is one of Shanghai's major relocation settlements. Our findings, from analysing a household survey and interviews, show that the sense of belonging and neighbourly relations of residents are poorer compared to before they were resettled. The analysis further reveals that residents who are more satisfied with their new housing and neighbourhood tend to have better neighbourly relations and sense of belonging compared to those who are not satisfied and feel they have lost out from the resettlement. Additionally, the state's efforts in rebuilding communities by providing more community organisations and activities have given residents a platform to encounter each other and help facilitate neighbourliness and a sense of belonging. Theoretically, our study contributes by revealing the interplay between residents and state-led community rebuilding efforts and how they have affected post-resettlement community relations.
