make the necessary checks for a proper definition, development and

implementation of the model when it is used for liquidity risk, interest rate

risk and business purposes.

Chapter 7, by Serena Di Rienzo, then reviews the literature on the two

main approaches – the economic value and the replicating portfolio

framework – which differ in both methodology and objective. The key

difference is their perspective, since the first aims to determine the economic

value of NMDs to allow a proper valuation of the risk and hedging of the

position, while the second is focused on the creation of a risk-balanced and

profitable investment strategy using NMDs.

In Chapter 8, Andreas Blöchlinger describes one of the first econometric

models that is useful from marketing to the hedging strategy. It develops a

coherent framework for NMDs, including the evolution of interest rates,

bank’s pricing behaviour, and customers’ withdrawal and prepayment

behaviour to derive a hedging strategy that generates a stable net interest

income. Chapter 9, by Rosa Cocozza, Domenico Curcio and Igor

Gianfrancesco, then describes a simple econometric model for the purpose of

managing interest rate risk. It shows how the NMDs volume can be easily

modelled into the regulatory time bands used in the maturity ladder, and the

pass-through of the bank can be estimated using a well-known econometric

technique.

Francesco Frascarelli and Vanessa Pagliaccia illustrate in Chapter 10 an

advanced econometric model that considers the customer’s demand for

money, composed by NMDs and other types of financial wealth whose

allocation depends on the financial markets. The model integrates customers’

asset allocation with the dynamics of the financial markets with the purpose

of forecasting both the liquidity and interest rate risk position. Chapter 11, by

Antonio Castagna, Antonio Scaravaggi and Bernardo Rapagnetta, then

presents an application of a stochastic risk factor model that integrates the

liquidity, profitability and interest rate risk. The model was calibrated to

artificial data to show that the heterogeneity of the NMDs dynamics and

customer’s behaviour can be modelled using this unique framework.

In Chapter 12, Bogusz Stankiewicz describes an empirical application of

how an NMD behavioural model can be used by banks’ marketing

departments. In particular, the model provides an understanding of how

modelling can contribute to an increase in business value. Following that,

Chapter 13 by Marco Palumbo presents a step-by-step approach for
