EBA 5th Research Workshop Summary

Core Content

The 5th EBA Research Workshop, held on 28–29 November 2016, focused on the topic of "Who is interested? Estimation of Demand on the Hungarian mortgage loan market in a discrete choice framework". The presentation was delivered by Akos Aczel from the Central Bank of Hungary, with additional insights provided by Walter Vecchiato from the European Banking Authority (EBA).

The study examines the decision-making process of consumers on the Hungarian mortgage loan market using a discrete choice model. It explores how individuals select a mortgage provider based on various factors, including interest rates, demographic characteristics, and geographic constraints. The analysis is grounded in data from the Hungarian credit registry, specifically focusing on newly granted domestic currency-denominated loans in 2015.

Main Points

Market Characteristics: The Hungarian mortgage loan market has limited bank presence, which makes the market microstructure a key factor in understanding consumer behavior.
Model Used: A conditional logit model is applied to estimate consumer demand, assuming utility maximization. This model helps analyze how consumers choose between different banks based on various attributes.
Choice Restrictions: Consumers' decisions are influenced by:
- Financial position (e.g., income level)
- Consumer characteristics (e.g., age)
- Banks' business models (e.g., target audience)
- Geographic constraints (e.g., proximity to bank branches)
Interest Rates: The study provides evidence that interest rates significantly impact consumer choices, indicating their central role in the decision-making process.
Demographic Factors: Demographic variables also play a crucial role in shaping the demand curve, suggesting that age and other personal characteristics affect loan preferences.

Key Information

Discrete Choice Models: The presentation references multinomial discrete choice models developed by scholars such as McFadden, Maddala, and Train. These models are used to analyze multiple choice scenarios in the banking sector, including deposit markets and consumer loans.
Market Microstructure: The analysis highlights the importance of market microstructure in influencing consumer decisions. It includes binary and multiple choices such as apply/not apply, accept/reject, choose the mortgage, and pay/failure to pay over time.
Limitations: The study acknowledges several limitations, including:
- Lack of credit risk parameters (e.g., scoring, probability of default (PD), loss given default (LGD))
- Missing relevant variables that could affect interest rate setting (e.g., instalment to disposable income ratio, customer loyalty)
Policy Implications: The findings suggest that:
- Discrete choice models, particularly nested logit models, can serve as a tool for analyzing business models in the mortgage sector.
- Market microstructure analysis is essential for addressing competition issues.
- Interest rates are a straightforward determinant of consumer behavior, highlighting their importance in policy and practice.
