This article examines whether, and to what extent, the announcement of new urban regeneration plans has influenced residential property values in Ulsan, Korea, where state-led initiatives have recently taken place to revitalize urban core areas in a more incremental and participatory manner. This is accomplished by analyzing data for single-family residential properties sold from January 2014 to December 2016 in the Ulsan Metropolitan area. A sample of 7139 transactions is used for hedonic analysis with consideration of the detailed timing of plan information dissemination from the beginning of the planning process to the release of the final plan. The results showed that the urban regeneration strategic plan’s release in December 2015 had a significant influence on the values of residential properties within and around the project sites, but this influence varied across neighborhoods. The effect of the plan release was found to be most significant in/around the project sites where residents showed a high level of willingness to participate. In these areas, price escalations were found to occur even before the release of the final plan, suggesting that appropriate planning interventions are required at early stages of urban regeneration projects to protect vulnerable groups of residents from potential displacement.

In this paper, the authors present a formulation of the multi-hop many-to-many Peer-to-Peer ride- matching problem, found in shared-ride applications. A many-to-many problem is one in which a rider can travel with multiple drivers, and a driver can carry multiple riders. The authors propose a pre- processing procedure to reduce the size of the problem. Furthermore, they devise a decomposition algorithm to solve the original ride-matching problem to optimality by means of solving multiple smaller problems. Finally, they demonstrate the computational efficiency of the proposed algorithm by solving randomly generated instances of the problem.

Most research on the performance of foreign versus domestic brands in emerging markets has examined dependent measures of product evaluation or purchase intention. However, consumers who intend to buy a product may switch to competing brands, thus displaying an intention–behavior discrepancy (IBD). Drawing on literature on country associations and dual process theory, the authors examine the performance of foreign versus domestic brands on IBD in emerging markets and the moderating role of consumer prior knowledge. They conduct an intention survey followed by a postpurchase survey in the Chinese automobile and smartphone industries and find that foreign brands have an advantage on IBD relative to domestic brands, indicating that they have the dual advantage of higher evaluations and lower IBDs. Furthermore, foreign brands’ advantage on IBD is smaller for consumers with inaccurate prior knowledge because they are more likely to systematically reprocess information and discount foreign brands’ favorable country associations. For these consumers, overestimating the product reduces foreign brands’ advantage to a lesser degree than underestimating it as a result of confirmation bias. These findings provide implications for brands in emerging markets.

Government transparency is generally uncontroversial, intuitively appealing, and held to be a cornerstone of planning practice. This article systematically reviews planning scholars’ treatment of government transparency in the twenty-first century. We find that transparency frequently underpins key theoretical constructs and policy prescriptions, but scholars rarely define or operationalize the term and generally treat it as unproblematic. We then identify how transparency requirements can conflict with the goals of accountability, participation, and inclusion, and we conclude by discussing the implications for assessing the role of transparency in social change.

The increasing diversity of vehicle type holdings and growing demand for BEVs and PHEVs have serious policy implications for travel demand and air pollution. Consequently, it is important to accurately predict or estimate the preference for vehicle holdings of households as well as the vehicle miles traveled by vehicle body- and fuel-type to project future VMT changes and mobile source emission levels. Leveraging the 2019 California Vehicle Survey data, this report presents the application of a utility-based model for multiple discreteness that combines multiple vehicle types with usage in an integrated model, specifically the MDCEV model. The model results suggest the important effects of household demographics, residence location, and built environment factors on vehicle body type and powertrain choice and usage. Further the predictions associated with changes inbuilt environment factors like population density can inform the design of land-use and transportation policies to influence household vehicle holdings and usage that can in turn impact travel demand and air quality issues in California.View the NCST Project Webpage
