• Unlike many other places around the globe, Hong Kong is a small city with a high population
    density. Some housing units are built near the sources of an externality, such as a landfill site. As the
    blocks of buildings are particularly tall, many are walled buildings that block the bad odor from
    the landfill. Thus, the wind blowing from a landfill site may not affect the entire building estate.
    Some buildings are more heavily affected than others, partly because walled buildings built near
    landfills are rare. Only a few studies currently examine the correlation between wind direction and
    the prices of walled buildings. In this paper, we aim to bridge this research gap by illustrating Hong
    Kong as a case study. Most previous research studies only examine a few factors affecting housing
    prices. Modern big data is characterized by its large volume of data, which includes various types of
    data that analysts would not necessarily sample, but instead merely observe to track what happens.
    Therefore, another innovative point of our paper, is that we adopt a big data approach to study this
    issue. In this aspect, this paper is the first of its kind. There are 53,071 observations in the 1999 to
    2014 dataset, with 2,175,911 data entries. Our results reflect that when more municipal solid waste
    is sent to the South East New Territories Landfill, residents’ complaints in Tseung Kwan O increase.
    However, entire property prices in the region also increase, which rejects our hypothesis. We speculate
    that as more people become aware of the housing estate due to complaints, with only a limited number
    of housing units affected by the smell, since the wind usually only blows in certain directions, the
    “advertisement effect” originating from complaints about the bad smell boosts the property prices of
    the unaffected units. That is, people become aware of the existence of the property, visit the site, and
    discover that only specific units facing one particular direction are affected. Then, they purchase units
    that are unaffected by the smelly wind, leading to an overall increase in property prices. The study’s
    results may provide a new perspective on urban planning, and possible implications for other cities in
    view of the constant increase in population and expansion of landfill sites.
