Evaluating quantitative easing: a DSGE approach

This paper develops a simple Dynamic Stochastic General Equilibrium (DSGE) model capable of evaluating the effect of large purchases of treasuries by central banks. The model exhibits imperfect asset substitutability between government bonds of different maturities and a feedback from the term structure to the macroeconomy. Both are generated through the introduction of portfolio adjustment frictions. As a result, the model is able to isolate the portfolio rebalancing channel of Quantitative Easing (QE). This theoretical framework is employed to evaluate the impact on yields and the macroeconomy of large purchases of medium- and long-term treasuries recently carried out in the US and UK. The results from the calibrated model suggest that large asset purchases of government assets had stimulating effects in terms of lower long-term yields, and higher output and inflation. The size of the effects is nevertheless sensitive to the speed of the exit strategy chosen by monetary authorities.

A DSGE Model with Endogenous Term Structure

In this paper, we propose a DSGE model with the term structure of interest rates drawing on the framework introduced by Andres et al. (2004) and Marzo et al. (2008). In particular, we reproduce segmentation in financial markets by introducing bonds of different maturities and bond adjustment costs non-zero at the steady state, introducing a structural liquidity frictions among bonds with different maturities: agents are assumed to pay a cost whenever they trade bonds. As a result, the model is able to generate a non-zero demand for bonds of different maturities, which become imperfect substitutes, due to differential liquidity conditions. The main properties of the model are analysed through both simulation and estimation exercises. The importance of the results are twofold. On one hand, the calibrated model is able to replicate the stylized facts regarding the yield curve and the term premium in the US over the period 1987:3-2011:3, without compromising its ability to match macro dynamics. On the other hand, the estimation, besides providing an empirical support to the theoretical setting, highlights the potentialities of the model to analyze the term premium in a microfounded macro framework. The results match very closely the behavior of actual yields, reflecting the recent activity of the Fed on longer maturities bonds.

Credit, Endogenous Collateral and Risky Assets: A DSGE Model

This paper proposes a new Dynamic Stochastic General Equilibrium (DSGE) model with credit frictions and a banking sector, which endogenizes loan-to-value (LTV) ratios of households and banks by expressing them as a function of systemic and idiosyncratic proxies for risk. Moreover, the model features endogenous balance sheet choices and a novel formulation of the targeted leverage ratio, in which assets are risk-weighted by risk-sensitivity measures. The results highlighted in this paper are important along two dimensions. First of all, the presence of endogenous LTV ratios exacerbates the procyclicality of lending conditions. Second, the model contributes to deeper understand the role of prudential regulatory frameworks in affecting business cycle fluctuations and in restoring macroeconomic and financial stability. The results suggest that when the economy is severely stressed by shocks originating in the financial sector, prudential regimes such as Basel II and Basel III are capable of downsizing substantially aggregate volatility, with Basel III found to be significantly more effective than Basel II.

Fiscal Policy Announcements of Italian Governments and Spread Reaction during the Sovereign Debt Crisis

This paper attempts to evaluate the effects of fiscal policy announcements by the Italian government on the long-term sovereign bond spread of Italy relative to Germany. After collecting data on relevant fiscal policy announcements, we perform an econometric comparative analysis between the three cabinets that followed one another during the period 2009-2013. The results suggest that only fiscal policy announcements made by members of Montis cabinet have been effective in influencing the Italian spread, revealing a remarkable credibility gap between Montis technocratic administration and Berlusconis and Lettas governments.

Domestic and multilateral effects of capital controls in emerging markets

Using a novel, high frequency dataset on capital control actions in 16 emerging market economies (EMEs) from 2001 to 2012, we provide new evidence on the domestic and multilateral effects of capital controls. Increases in capital account openness reduce monetary policy autonomy and increase exchange rate stability, confirming the constraints of the monetary policy trilemma. Both gross in- and outflows rise, while the effect on net capital flows is ambiguous. Tighter capital inflow restrictions generated significant spillovers, especially in the post-2008 environment of abundant global liquidity. We also find evidence of a domestic policy response to foreign capital control changes in countries that are affected by these spillovers.
