Background

Department of Urban Planning , NCKU, Taiwan

Background

What are the public interests related to urban renewal projects?– Prevention of multiple hazards (fire,

earthquake, flooding, etc.)• Provision of open spaces

– Reduction of traffic accidents• Provision of walkways and bike paths

– Reduction of poverty & crime rates– Aesthetic values

7

Department of Urban Planning , NCKU, Taiwan

Background

Why is urban renewal an unfair game?– Proposals are often submitted by developers– Landowners don’t have complete information

of local housing market– Tenants can’t participate in urban renewal– Shop owners usually can’t keep their shops

after renewal

8

Department of Urban Planning , NCKU, Taiwan

Background

Why urban renewal projects become free lunches for all stakeholders?– Projects are financed based on floor-area

ratio (FAR) incentives

Who pays these free lunches?– High FAR justified by Transit-Oriented

Development (TOD) may deteriorate the service quality of public facilities and infrastructure

9

MotivationTo estimate both the option values &

intrinsic values of parcels in Taipei by taking into account urban renewal restrictions & demolition costs

To assist landowners to make the right decisions

To modify the rule of urban renewal by setting up new formula for profit allocation games

10

Department of Urban Planning , NCKU, Taiwan

FAR incentives should be a good tool to promote public interests as to prevent market failures cause by– Potential hazards– Social costs associated with poverty,

crimes, and traffic accidents

FAR incentive creates debts on future renewal practices

Methodology Cooperative Games

– Profit imputations among landlords and developers

Bargaining Games– Sequential bargaining under asymmetric information

among landlords and developers

Project Assessment on Urban Renewal Policy– Values of public interests regarding urban renewal

practices

MethodologyHedonic Functions

– Log-linear and semi-log functions are pre-specified functions while Box-Cox functions maximize the log-likelihood of the functions within a pre-specified family of functions

– It is often advisable to compare the results of different functional forms in order to identify non-robust estimates

The functional forms of our models– Double-log and Box-Cox transformation

The Data The Data

– Transaction property prices before and after urban renewal projects in Taipei from 2003 to 2011

– Makes use of sales prices rather than rents• Accounts for most transactions• Sales prices reflects future expectations

– Other data• Construction (hard) and soft costs• Housing Price Index

– Sources• Department of Land Administration, Ministry of Interior• Urban renewal developers• Real estate agents

Estimation Approaches

19

Expectations & Variations of Asset Values– Hedonic housing price functions– Zoning & renewal constraints– FAR incentives

Risks & Public Interests Related to Urban Renewal Projects– Costs of Negotiation (repeated games)– Scale of Development (cooperative games)– Reject & Resubmit (majority games)– Demand & Supply Analysis on Housing Market– Assessment of Multiple Hazards– Evaluation of Social Costs & Aesthetic Values

Department of Urban Planning , NCKU, Taiwan

Our Missions– To help developers & landlords make

decisions on urban renewal proposals– To refine urban renewal regulations

Our Challenges– The quantification of risks and public

interests associated with housing policy and urban renewal practices
