This paper develops an estimable hybrid model that combines the theoretical rigor of a micro-founded DSGE model with the flexibility of an atheoretical VAR model. The model is estimated via maximum likelihood technique based on quarterly data on real Gross National Product (GNP), consumption,...

This paper develops a dynamic general equilibrium model with endogenous default on entrepreneur loans and funds borrowed from the central bank (liquidity injections) and investigates the welfare cost of sovereign default. The results show that sovereign default affects production through...

This paper establishes the prevailing financial factors that influence credit spread variability, and its impact on the U.S. business cycle over the Great Moderation and Great Recession periods. To do so, we develop a dynamic general equilibrium framework with a central role of financial...

This paper studies the role of the equity price channel in business cycle fluctuations, and highlights the equity price channel as a different aspect to general equilibrium models with financial frictions and, as a result, emphasizes the systemic influence of financial markets on the real...

This paper studies the role of the equity price channel in business cycle fluctuations, and highlights its systemic risk across all sectors of the economy. We develop a canonical New-Keynesian dynamic stochastic general equilibrium model with a tractable role for the equity market in banking,...

This thesis comprises of six independent chapters, besides the introduction and conclusions, with the common theme of optimal public policies in dynamic general equilibriummodels with different kinds of distortions. Broadly speaking, the issues considered are:tax evasion, bureaucratic...

The aim of the thesis is to address issues concerning modelling and evaluation of monetary policy by obtaining targeting rules from optimisation techniques using welfare loss functions that capture asymmetries and zone targeting behaviours. The motivation is that the specification of the most...
