His research focuses on the economics of intermediation broadly defined with a special focus on real estate brokerage. His research interests include real estate brokerage, mortgage contracts, economics of information, and experimental economics. He also uses laboratory experiments to advance understanding of market players’ deviations from the predictions generated by rational models.

Yavas has authored or co-authored more than 50 articles in peer-reviewed journals on real estate, finance, and economics.

The results of his research have been cited in some of the nationally known publications, including The Wall Street Journal, Time, Money, BusinessWeek, The Philadelphia Inquirer, and Boston Sunday Globe.
He has consulted for mortgage companies and real estate investment trusts.

Yavas is a world-renowned economist. In 2001, he made the World's Top 500 Economists list, according to the number of articles published, prepared by Tom Coupé and sponsored by the European Economic Association.

He was ranked 6th on the list of Top 50 Authors for publications in Base Real Estate Journals between 1994-1998 by the Journal of Real Estate Literature. Yavas serves on the Monetary Policy Committee of the Central Bank of the Republic of Turkey.

He earned his Ph.D. in economics from the University of Iowa.

Ikramov , N., & Yavas, A. (2012). Asset Characteristics and Boom and Bust Periods: An Experimental Study.
Article AbstractWe examine the impact of transaction costs, short selling restrictions and divisibility of assets on market efficiency in experimental asset markets. We find that transaction costs do not exacerbate the inefficiency of the market. They reduce the magnitude of bubbles and push prices closer to fundamentals. More divisible assets exhibit smaller deviations of prices from fundamentals. Short selling restrictions contribute to prolonged bubbles, while relaxing them increases the occurrence of "bust cycles." We also find that experimental real estate markets display larger deviations of prices from fundamental values, longer boom and bust cycles and smaller turnover than experimental financial markets.

Agarwal, S., Chang, Y., & Yavas, A. (2012). Adverse Selection in Mortgage Securization.
Article AbstractWe investigate lenders’ choice of loans to securitize and whether the loans they sell into the secondary mortgage market are riskier than the loans they retain in their portfolios. Using a large dataset of mortgage loans originated between 2004 and 2008, we find that banks sold low-default risk loans into the secondary market while keeping higher-default risk loans in their portfolios. This result holds for both subprime and prime loans. We do find strong support for adverse selection with respect to prepayment risk; securitized loans had higher prepayment risk than portfolio loans. It appears that in return for selling loans with lower default risk, lenders retain loans with lower prepayment risk. Small lenders place more emphasis than large lenders on default risk versus prepayment risk of the loans they retain. Securitization strategies of lenders changed during the sample period as they became less willing to retain higher-default loans after the housing market reached its peak. There are also differences in the performance of loans sold to GSEs and loans sold to private issuers. Loans sold to private issuers have lower prepayment rates in each year while relative default rates vary across the years.

Rutherford, R., & Yavas, A. (2012). Discount Brokerage in Residential Real Estate Markets.
Article AbstractTransaction costs are thought to affect asset prices and market liquidity, but the direction and magnitude of these effects continues to be the subject of debate. In the single family residential market discount brokers offer to list a house for a lower price and thus reduce the transaction costs associated with obtaining a match. In this paper we obtain empirical estimates of the price and liquidity impact of a seller selecting a discount broker to market a single family residential property. The unique data set allows for the identification of residential properties that were listed by a discount brokerage firm. The empirical results confirm the predictions of our theoretical model. Using a sample of 318,211 listings and 243,625 sales, we find that houses listed by discount brokers sell at prices similar to non-discount brokerage listings, but are less likely to sell and when they do sell, take approximately 3 days longer to sell. The results indicate that lower transaction costs do not impact housing prices in this market, but are related to asset liquidity.

Yildirim, Y., & Yavas, A. (2011). Price Discovery in Real Estate Markets: A dynamic Analysis.
Article AbstractAlthough the correlation between the public and private market pricing of real estate has generated considerable research effort, the methods utilized in previous studies have failed to capture the dynamic nature of this correlation. This paper proposes a new statistical method to address this issue. This method, known as the dynamic conditional correlation GARCH model, enables us to study the dynamics of the correlation between the two markets over time and enrich our understanding of the public and private market pricing of real assets. We find that the correlation between NAV returns and REIT returns is dynamic for all REIT types and there is a strong degree of persistence in the series of correlation. Our Granger-causality tests show that price discovery generally takes place in the securitized public market. However, we also find significant variations across property types and individual firms within each type. Our results indicate that constructing an optimal portfolio requires firm level analysis of causality and correlation between REIT returns and NAV returns.

Fisher, L., & Yavas, A. (2010). Case for Percentage Commission Contracts: The Impact of a "Race" Among Agents.
Article AbstractIn standard principal-agent problems, the issue at hand is how to align the interests of the agent with those of her principal. A commonly used contract involves the principal paying the agent a percentage of the sale price as commission. With respect to real estate brokerage conracts, it has been argued that percentage commission contracts fail to provide sufficient incentives to the agent. This paper re-evaluates the standard solution to a one seller, one agent agency problem by introducing more than one agent. It is shown that percentage commission contracts can induce first-best effort levels from agents. The result is due to the negative externalities created by the winner-takes-all race among agents. The optimal commission rates in this model are inconsistent, however, with the observed uniformity in commission rates across markets in the U.S.

Article AbstractUtilizing individual mortgage data, we find that borrowers with points are less likely to refinance, and when they do, they take longer to refinance. This finding supports the separating equilibrium prediction of earlier studies that borrowers with higher (lower) refinancing costs self-select into mortgages with higher-point/lower-rate (lower-point/higher-rate) loans.

Article AbstractWe conduct an experimental test of a screening model of an insurance market with asymmetric information. We first conduct three sessions in which the proportion of high risk buyers is such that a separating equilibrium should exist. We then conduct three more sessions in which the only change we make is decreasing the proportion of high risks such that the equilibrium is now a pooling equilibrium. In both treatments, the observed behavior converges to the equilibrium prediction.

Yavas, A., Anbrose, B., & Sanders, A. Servicers and Mortgage-Backed Securities Default: Theory and Evidence.
Article AbstractWe study conflicting incentives of the master and special servicers in handling troubled loans in a CMBS deal and how the frictions between the interests of the two servicers might be diminished if the master and special servicing rights are held by the same firm. We show that concentrating both servicing rights in one firm reduces the likelihood that a defaulted loan terminates in foreclosure.
