Real Estate & Financial Markets (REFM) Lab
Mission and Organization
10/11/2013 1 Fisher Center for Real Estate & Urban Economics
REFM Lab Mission
• Provide modeling and analytic technology, data, hardware, software,
and personnel needed to conduct economic analyses of real estate
asset and capital markets. Develop scientific advances in valuation
methods and systemic risk management practices needed for
trading and monitoring activities in these markets.

REFM Lab – Goals
• Our Goals:
– Contribute to the policy debate on the risk channels associated with real estate and mortgage markets in the U.S.
• Macro and micro-economic foundations of real estate cycles,
• Effects of monetary policy on mortgage capital market flows.
• Supply and demand dynamics in housing and commercial real estate markets, including the effects of transportation infrastructure, job creation, and migration.
• Develop and monitor house price indices.
– Develop real estate and mortgage market risk management tools.
• Interest rate, credit, and energy risk.
• New metrics for systemic and regional components of these risks.
– Establish risk analytics for the primary real estate energy sources – natural gas and electricity
• Identify optimal capital market incentives for improving the energy efficiency of U.S. real estate markets.

REFM Lab – Where we want to be
• Overarching Goals:
– Develop a large research data center focused on real estate asset and capital markets.
• Center design includes IT infrastructure and security systems for large and often proprietary data sets.
– Undertake high-quality academic research, to publish the findings of this research in academic journals and other practitioner outlets, and to promote data-based graduate student training that is focused on these markets.
• Immediate Needs:
– Establish a high-performance and flexible hardware / software architecture that • Provides concurrent access to the REFM Lab datasets through a high-speed network
• Benefits from the existing processing power
– Users already holding powerful computers at their desktops can run processes locally
– All users, including those without powerful local computational resources, have access to a shared processing facility composed of powerful compute servers
– Implement a structured approach for granting user access to the lab datasets and running processes for analyzing data
– Create a systematic approach for backing up lab datasets

REFM Lab Architecture – Next Steps
• Integrate REFM Lab with other scientific Labs such as Computer Science’s,
Lawrence Berkeley, etc…
• Continue to expand the datasets
– USGS National Elevation Dataset (Geospatial Data)
– NRCS Gridded Soil Survey Geographical Database (Geospatial Data)
– DataQuick – Nationwide residential house price and transaction data
– Bridge into other external datasets such as Nielsen’s data
– Etc…
• Establish a data model for REFM’s datasets

Dynamic House Price Indices: Designed for
Fixed Income Valuation
• Price Indices Require: Controls for the evolution of “Prices” and for
the evolution of the “Characteristics” (Quantity of Housing Services)
for each house.
– Current repeat sales indices do not do this!
• Our estimator includes two Poisson processes: 1) likelihood of re-
modelling and 2) likelihood of sale.
– Controls for the housing characteristics and the probability that these
characteristics will change as a function of macro fundamentals.
– Controls for the probability of sale as a function of macro fundamentals.
• Conditioned on these intensities: Use classical linear filtering
techniques to estimate underlying “index”
– Model includes reasonable assumptions for the long term average
dynamics (mean reversion) of house prices and the dynamics of the
volatility of house prices.
