Motivated by the apparent failure of the credit multiplier mechanism (CM) to deliver amplification in DSGE models, we re-examine its role in business cycles to address the question: is something wrong with the CM? Our answer is no. In coming to this answer we construct a model with reproducible...

We provide a model with sector-specific debt-collateral constraints to analyse how asymmetric financing conditions across sectors affect the aggregate investment, credit and output composition. In our model, investments in the construction sector allow for higher leverage than investments in the...

We explore shocks to expected future productivity in a model with limited enforcement of financial contracts. A microfounded collateral constraint implies that good news about future productivity yield an increase in stock prices, available credit and a general economic expansion.

In this paper our main aim is to quantify the role that housing collateral plays for the monetary transmission mechanism. Furthermore, we want to explore the implications of the increase in household indebtedness, and specifically the loan-to-value ratio, in the last two decades. We set up a two...

In this paper, I investigate the characteristics of house price dynamics for a sample of 16 emerging economies from Asia and Central and Eastern Europe, over the period 1995-2011. Linking housing valuations to a set of conventional fundamental determinants � relative to both the supply and...

The volume collects the essays presented at the 15th Workshop on Public Finance organised by Banca d'Italia in Perugia from 4 to 6 April 2013. The workshop focused on the link between fiscal policy and macroeconomic imbalances and comprised four sessions. The first session concentrated on the...

This paper builds models of nonlinear dynamics in the aggregate investment and borrower net worth to study the causes and nature of endogenous credit cycles. The basic model has two types of projects: the Good and the Bad. The Good projects rely on the inputs supplied by others who could...

We study the effects of credit shocks in a model with heterogeneous entrepreneurs, financing constraints, and a realistic firm-size distribution. As entrepreneurial firms can grow only slowly and rely heavily on retained earnings to expand the size of their business, we show that, by reducing...

This survey reviews the research regarding the general frameworks used for the specification of financial market frictions in dynamic stochastic general equilibrium (DSGE) models. Within the related literature, financial frictions are considered to be the prime candidates for endogenous...
