As a real estate economist, I am keen to 1) advance our understanding of real estate as a consumption good, an investment asset, and a policy instrument, and 2) discover and explain how developers, investors, occupiers, and agents behave in an \u2018inefficient\u2019 market. Research, like a coffee filter (I make pour-over coffee everyday!), is to distill information from noise, and knowledge from belief.<\/p>\n\n\n\n<p>Here are some of the research questions I have tried to answer.  What determines real estate liquidity?  How does liquidity affect transmission of price information, hence predictability of property price movements?  How do short-term investors (including agents) take advantage of incomplete information?  Does taxing them stabilize home prices?  What determines if developers have market power in selling their new properties?  How are the risks of buying pre-sale (off-plan) properties priced, and does mandating developers to disclose more information help?  What governance problems does subdividing ownership create, and how is the redevelopment potential of old properties affected?  What locations would enjoy higher capital appreciation during a boom?  Do these locations also fall more during a bust?  So on so forth.<\/p>\n\n\n\n<div class=\"alignnormal\"><div id=\"metaslider-id-760\" style=\"width: 100%;\" class=\"ml-slider-3-99-0 metaslider metaslider-flex metaslider-760 ml-slider ms-theme-simply-dark has-dots-nav\" role=\"region\" aria-label=\"Paper slides\" data-width=\"650\">\n    <div id=\"metaslider_container_760\">\n        <div id=\"metaslider_760\">\n            <ul class='slides'>\n                <li style=\"display: block; width: 100%;\" class=\"slide-761 ms-image \" aria-roledescription=\"slide\" data-date=\"2023-05-25 15:20:19\"><a href=\"https:\/\/papers.ssrn.com\/sol3\/papers.cfm?abstract_id=4205382\" target=\"_blank\" aria-label=\"View Slide Details\" class=\"metaslider_image_link\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/rec.hku.hk\/skkelvin\/wp-content\/uploads\/2023\/05\/yoav-aziz-T4ciXluAvIE-unsplash-scaled-650x250.jpg\" height=\"250\" width=\"650\" alt=\"Is this time the same?

The real estate market is the laboratory for me to conduct experiments and answer these questions. I have therefore established the <a href=\"https:\/\/relab.hku.hk\" target=\"_blank\" rel=\"noopener\" title=\"\">HKU Real Estate Lab<\/a> to make our research ideas and findings more accessible to the industry, the government, and the community at large. For example, a map was created to visualize the <a href=\"https:\/\/relab.hku.hk\/price_map\/\" target=\"_blank\" rel=\"noopener\" title=\"\">home price changes across 18 districts in Hong Kong<\/a> since 1993, and a <a href=\"https:\/\/relab.hku.hk\/price_rank_dist\/\" target=\"_blank\" rel=\"noopener\" title=\"league table\">league table<\/a> was built to rank the &#8216;winner&#8217; and &#8216;loser&#8217; districts each year. <\/p>\n\n\n\n<p>I am also interested in the methodology of property performance measurement, which is the bread and butter of every real estate analysis.  For example, I developed an online teaching case using <a href=\"https:\/\/www.acrc.hku.hk\/Case\/Detail\/1130\" target=\"_blank\" rel=\"noopener\" title=\"\">property analytics for valuation<\/a>.  I also co-invented the <a href=\"http:\/\/hkureis.versitech.hku.hk\/\" target=\"_blank\" rel=\"noreferrer noopener\">repeat-sales property price index<\/a> in Hong Kong, which became the first tradable housing price index in Asia.<\/p>\n\n\n\n<p>Check my <a href=\"https:\/\/rec.hku.hk\/skkelvin\/wp-content\/uploads\/2023\/05\/OnlineCV_2023.pdf\" target=\"_blank\" rel=\"noopener\" title=\"OnlineCV_2023\">CV<\/a> for my list of publications.
