Race and the Production of Extreme Land Abandonment in the American Rust Belt

Extreme land abandonment is one of the most visible expressions of urban decline. Conventional theory emphasizes housing lifecycle processes, municipal fiscal challenges and deindustrialization to explain its prevalence. Empirically however, these factors are not strongly associated with the most extreme instances of land abandonment in the American Rust Belt. Race, by contrast, is strongly associated with these patterns, yet there is little mention of it in conventional theory. This article draws on group threat theory to explain how the construction of Blackness as a threat to white property, power and political influence, has propelled the production of extreme land abandonment. The constructed threat has translated into a sustained suppression of demand and capital for overwhelmingly black neighborhoods. These forces operate both independently and as an accelerant for other abandonment drivers.     

Mobile phone network data reveal nationwide economic value of coastal tourism under climate change

The technology-driven application of big data is expected to assist policymaking towards sustainable development; however, the relevant literature has not addressed human welfare under climate change, which limits the understanding of climate change impacts on human societies. We present the first application of unique mobile phone network data to evaluate the current nation-wide human welfare of coastal tourism at Japanese beaches and project the value change using the four climate change scenarios. The results show that the projected national economic value loss rates are more significant than the projected national physical beach loss rates. Our findings demonstrate regional differences in recreational values: most southern beaches with larger current values would disappear, while the current small values of the northern beaches would remain. These changes imply that the ranks of the beaches, based on economic values, would enable policymakers to discuss management priorities under climate change.     

SHIFTING BOUNDARIES IN ECONOMICS: THE INSTITUTIONAL COGNITIVE STRAND AND THE FUTURE OF INSTITUTIONAL ECONOMICS

This paper aims at contributing to the debate on the future of institutional economics and of the field as a whole by starting from the literature that discusses the relationship between Old‐Original Institutional Economics and New Institutional Economics. It suggests that the process of reunifying OIE and NIE (and evolutionary economics) prompted by part of the literature could be improved by the contribution of the Cognitive Institutional Economics. The paper follows a two‐stage pathway: first, it frames the debate on the relationships between NIE and the OIE and it concentrates on a subset of the literature that shows that NIE's recent developments complicate the distinction between NIE and OIE, and it explores the possibility that NIE and OIE may merge so that an amalgam of NIE, OIE and Evolutionary Economics becomes the next economic paradigm. Secondly, the paper argues that a step forward in the direction outlined by the literature has been made by CIE, which is a research stream that developed from cross‐fertilization among NIE, OIE and the Hayekian contributions to the analysis of institutions. In the concluding remarks, the possible emergence of a single institutional paradigm is discussed in the light of the literature about change in economics.

Assessing the effect of food retail subsidies on the price of food in remote Indigenous communities in Canada

The Canadian government currently subsidizes food retailers in the 25 remote communities in Nunavut through the Nutrition North Canada program. The program expects each dollar of the food subsidy to be fully passed on to the consumer in the form of lower prices. Unfortunately, existing audits and reviews of the program have failed to determine the pass-through rate of the subsidy. Using regression analysis on food price data in each of the 25 communities, subsidy rates, and covariates that control for community characteristics, we overcome the limitations of past research and provide the first-ever estimate of the pass-through rate of Nutrition North in Nunavut. Our results suggest that most, if not all, of the subsidy is passed on to the consumer in lower food prices.     

我国煤炭资源分布"北多南少"成因探析

我国煤炭资源储量丰富,它分布广,种类繁多。据我国第二次煤田预测资料显示,埋深1000m以浅的煤炭总资源量为2．6万亿t。其中大别山-秦岭-昆仑山一线以北地区资源量约2．45万亿t,占全国总资源量的94％;以南的广大地区仅占6％左右。这样出现了北方多（尤其华北、西北多）,南方少（尤其东南沿海少）的格局。文中就我国煤炭资源“北多南少”这种特点,从两方面探讨了其原因。     

Value-based network mobilization: A case study of modern environmental networkers

This article addresses current environmental issues by taking a network perspective to examine the initiatives to solve them. Previous investigations of network dynamics and mobilization concern the business context, but we broaden the analysis to the societal networks wherein business is embedded. Our aim is to investigate the early emergence of collective action around a common issue. We analyze the network mobilizers, who promote the issue and its solutions, and the mobilization mechanisms that they employ. We have conducted a case study that examines three initiatives to save the Baltic Sea, all involving business, governmental, and civil society actors. This rich case material leads us to formulate a conceptual model of value-based network mobilization. The mobilizing actors, values, and relationship sediments emerge as important factors in creating issue networks. Our key contribution is to show how the environmental issues bring new types of actors to networks and change the rules of the game. We propose that ‘modern environmental networkers’ should become more important in the future, and that business firms need to develop their skills in playing the new games with these new actors.
