  • Steffen Andersen, Cristian Badarinza, Lu Liu, Julie Marx, Tarun Ramadorai (2022), Reference Dependence in the Housing Market, American Economic Review, 112 (10), pp. 3398-3440.

    Abstract: We quantify reference dependence and loss aversion in the housing market using rich Danish administrative data. Our structural model includes loss aversion, reference dependence, financial constraints, and a sale decision, and matches key nonparametric moments, including a "hockey stick" in listing prices with nominal gains, and bunching at zero realized nominal gains. Households derive substantial utility from gains over the original house purchase price; losses affect households roughly 2.5 times more than gains. The model helps explain the positive correlation between aggregate house prices and turnover, but cannot explain visible attenuation in reference dependence when households are more financially constrained.

  • Lu Liu, The Demand for Long-Term Mortgage Contracts and the Role of Collateral.

    Abstract: Long-term fixed-rate mortgage contracts protect households against interest rate risk. Using administrative data from the UK, the paper shows that the choice of fixation length is affected by the life-cycle dimension of credit risk in the mortgage market: the loan-to-value (LTV) ratio declines and collateral coverage improves over the life of the loan due to principal repayment and house price appreciation. High-LTV borrowers face a trade-off between their demand to insure against repricing, and obtaining a lower credit spread over time using shorter-term contracts. To quantify demand for longer-term contracts, I develop a life-cycle model of optimal mortgage fixation choice. With baseline house price growth and interest rate risk, high-LTV households prefer shorter-term contracts, in line with the data. The paper proposes a mechanism that reduces pooling in longer-term contracts in high-LTV segments of the mortgage market, and helps explain the prevalence of relatively short mortgage fixation lengths across countries.

  • Jack Fisher, Alessandro Gavazza, Lu Liu, Tarun Ramadorai, Jagdish Tripathy (Draft), Refinancing Cross-Subsidies in the Mortgage Market.

    Abstract: In household finance markets, inactive households can implicitly cross-subsidize active households who promptly respond to financial incentives. We assess the magnitude and distribution of cross-subsidies in the mortgage market. To do so, we build a model of household mortgage refinancing and structurally estimate it on rich administrative data on the stock of outstanding UK mortgages in June 2015. We estimate sizeable cross-subsidies during this sample period, from relatively poorer households and those located in less-wealthy areas towards richer households and those located in wealthier areas. Our work highlights how the design of household finance markets can contribute to wealth inequality.

  • Lu Liu, Non-Salient Fees in the Mortgage Market.

    Abstract: This paper studies supply-side product pricing when consumers underreact to non-salient fees. Using comprehensive data on issued and offered mortgages in the UK, I document that lenders differ substantially in the fees they charge, and that borrowers appear less overall cost-sensitive to products with fees. In order to distinguish from demand factors such as unobservable preferences or product characteristics, I show that lenders pass on firm-specific funding cost shocks via fees, but not interest rates, consistent with strategic pricing of fees, and maintaining competitive prices in the salient price dimension, interest rates. I further find heterogeneity in pricing across lenders: those who rely on high fees tend to have higher funding cost, lower return on equity and larger branch networks, in line with a specialization equilibrium in which high-cost lenders are able to match with less cost-sensitive consumers.

All Courses

  • FNCE2510 - Fnce of Buyouts & Acqs

    The course focuses on financial tools, techniques, and best practices used in buyouts (financial buyers) and acquisitions (strategic buyers). While it will touch upon various strategic, organizational, and general management issues, the main lens for studying these transactions will be a financial one. It will explore how different buyers approach the process of finding, evaluating, and analyzing opportunities in the corporate-control market; how they structure deals and how deal structure affects both value creation and value division; how they add value after transaction completion; and how they realize their ultimate objectives (such as enhanced market position or a profitable exit). The course is divided into two broad modules. The first module covers mergers and acquisitions, and the second one studies buyouts by private equity partnerships. FNCE 2030 or FNCE 2070 are recommended.
