Three Essays on Unconventional Monetary Policy at the Zero Lower BoundZhang, Yang 29 November 2013 (has links)
In the first chapter “Impact of Quantitative Easing at the Zero Lower Bound (with J. Dorich, R. Mendes)”, we introduce imperfect asset substitution and segmented asset markets, along the lines of Andres et al. (2004), in an otherwise standard small open-economy model with nominal rigidities. We estimate the model using Canadian data. We use the model to provide a quantitative assessment of the macroeconomic impact of quantitative easing (QE) when the policy rate is at its effective lower bound. In the second chapter “Impact of Forward Guidance at the Zero Lower Bound”, I consider alternative monetary policy rules under commitment in a calibrated three-equation New Keynesian model and examine the extent to which forward guidance helps to mitigate the negative real impact of the zero lower bound. The simulation results suggest that the conditional statement policy prolongs the zero lower bound duration for an additional 4 quarters and reverses half of the decline in inflation associated with the lower bound. It even generates a period of overshooting in inflation three quarters after the initial negative demand shock. Alternatively, the effect of price-level targeting as a forward guidance policy at the zero lower bound is slightly different. In the third chapter “Impact of Quantitative Easing on Household Deleveraging”, I extend the DSGE model in the first chapter with some financial frictions to explore the effects of QE on asset prices and household balance sheet. There are two effects of QE on aggregate output originated from the model. First, QE leads to a decline in term premium, which increases current consumption relative to future consumption. Second, it leads to a lower loan to collateral value ratio and a decline in external finance premium. Favorable financing condition encourages further accumulation of household debt at cheaper rates, in turn, leads to an immediate higher household debt to income ratio. In the consideration of the future withdrawal of any stimulus provided from QE, this would pose greater challenges as it implies much intensive household deleveraging process. I provide some sensitivity analysis around key parameters of the model.

Spillovers from US monetary policy: Evidence from a time-varying parameter global vector autoregressive modelCrespo Cuaresma, Jesus, Doppelhofer, Gernot, Feldkircher, Martin, Huber, Florian 08 February 2019 (has links) (PDF)
The paper develops a global vector auto-regressive model with time varying pa-
rameters and stochastic volatility to analyse whether international spillovers of US monetary
policy have changed over time. The model proposed enables us to assess whether coefficients
evolve gradually over time or are better characterized by infrequent, but large, breaks. Our find-
ings point towards pronounced changes in the international transmission of US monetary policy
throughout the sample period, especially so for the reaction of international output, equity prices
and exchange rates against the US dollar. In general, the strength of spillovers has weakened
in the aftermath of the global financial crisis. Using simple panel regressions, we link the vari-
ation in international responses to measures of trade and financial globalization. We find that
a broad trade base and a high degree of financial integration with the world economy tend to
cushion risks stemming from a foreign shock such as US tightening of monetary policy, whereas
a reduction in trade barriers and/or a liberalization of the capital account increase these risks.

Abenomics: Towards Brighter Future or More of the Same? / Abenomics: Vstříc světlejším zítřkům, nebo stále to samé?Pinta, Ondřej January 2014 (has links)
This thesis investigates the impact of Abenomics policies, named after the new Japanese Prime Minister Shinzo Abe, on the economy. His so-called "three arrows" agenda includes fiscal expansion, quantitative and qualitative monetary easing, and regulatory reforms. This work focuses on the assessment of the fulfillment of set goals and compares Abenomics to previous policies. Abe's cabinet succeeded in raising inflation and depreciating yen. The debt growth has almost halted and the GDP has mildly recovered. However, the economy is still far from stable. This thesis also explores further issues encountered by the Japanese economy such as the shut-down of nuclear power plants and effects of the zero lower bound constraint. This work introduces a synthetic counterfactual to assess the real results of Abenomics. This method builds a model of an alternate Japan, in which Abe had not assumed the office. The results suggest that the impact of Abenomics on the GDP per capita is slightly positive or negligible.

International Housing Markets, Unconventional Monetary Policy and the Zero Lower BoundHuber, Florian, Punzi, Maria Teresa 25 January 2016 (has links) (PDF)
In this paper we propose a time-varying parameter VAR model for the housing market in the United States, the United Kingdom, Japan and the Euro Area. For these four economies, we answer the following research questions: (i) How can we evaluate the stance of monetary policy when the policy rate hits the zero lower bound? (ii) Can developments in the housing market still be explained by policy measures adopted by central banks? (iii) Did central banks succeed in mitigating the detrimental impact of the financial crisis on selected housing variables? We analyze the relationship between unconventional monetary policy and the housing markets by using the shadow interest rate estimated by Krippner (2013b). Our findings suggest that the monetary policy transmission mechanism to the housing market has not changed with the implementation of quantitative easing or forward guidance, and central banks can affect the composition of an investors portfolio through investment in housing. A counterfactual exercise provides some evidence that unconventional monetary policy has been particularly successful in dampening the consequences of the financial crisis on housing markets in the United States, while the effects are more muted in the other countries considered in this study.

The shortage of safe assets in the US investment portfolio: Some international evidenceHuber, Florian, Punzi, Maria Teresa 03 1900 (has links) (PDF)
This paper develops a Bayesian Global VAR (GVAR) model to track the international transmission dynamics of two stylized shocks, namely a supply and demand shock to US-based safe assets. Our main findings can be summarized as follows. First, we find that (positive) supply-sided shocks lead to pronounced increases in economic activity which spills over to foreign countries. The impact of supply-sided shocks can also be seen for other quantities of interest, most notably equity prices and exchange rates in Europe. Second, a demand-sided shock leads to an appreciation of the US dollar and generally lower yields on US securities, forcing investors to shift their portfolios towards foreign fixed income securities. This yields sizable positive effects on US output, equity prices and a general decrease in financial market volatility. / Series: Department of Economics Working Paper Series

Global Spillover Effects from Unconventional Monetary Policy During the CrisisSolís González, Brenda January 2015 (has links)
This work investigates the international spillover effects and transmission channels of Unconventional Monetary Policy (UMP) of major central banks from United States, United Kingdom, Japan and Europe to Latin-American countries. A Global VAR model is estimated to analyze the impact on output, inflation, credit, equity prices and money growth on the selected countries. Results suggest that indeed, there are international spillovers to the region with money growth, stock prices and international reserves as the main transmission channels. In addition, outcomes are different between countries and variables implying not only that transmission channels are not same across the region but also that the effects of the monetary policy are not distributed equally. Furthermore, it is found evidence that for some countries transmission channels may have transformed due to the crisis. Finally, effects of UMP during the crisis were in general positive with exception of Japan indicating that policies from this country brought more costs than benefits to the region. Keywords Zero Lower Bound, Unconventional Monetary Policy, International Spillovers, Global VAR, GVAR.

Monetary Policy and the Great RecessionBundick, Brent January 2014 (has links)
Thesis advisor: Susanto Basu / The Great Recession is arguably the most important macroeconomic event of the last three decades. Prior to the collapse of national output during 2008 and 2009, the United States experienced a sustained period of good economic outcomes with only two mild and short recessions. In addition to the severity of the recession, several characteristics of this recession signify it as as a unique event in the recent economic history of the United States. Some of these unique features include the following: Large Increase in Uncertainty About the Future: The Great Recession and its subsequent slow recovery have been marked by a large increase in uncertainty about the future. Uncertainty, as measured by the VIX index of implied stock market volatility, peaked at the end of 2008 and has remained volatile over the past few years. Many economists and the financial press believe the large increase in uncertainty may have played a role in the Great Recession and subsequent slow recovery. For example, Kocherlakota (2010) states, ``I've been emphasizing uncertainties in the labor market. More generally, I believe that overall uncertainty is a large drag on the economic recovery.'' In addition, Nobel laureate economist Peter Diamond argues, ``What's critical right now is not the functioning of the labor market, but the limits on the demand for labor coming from the great caution on the side of both consumers and firms because of the great uncertainty of what's going to happen next.'' Zero Bound on Nominal Interest Rates: The Federal Reserve plays a key role in offsetting the negative impact of fluctuations in the economy. During normal times, the central bank typically lowers nominal short-term interest rates in response to declines in inflation and output. Since the end of 2008, however, the Federal Reserve has been unable to lower its nominal policy rate due to the zero lower bound on nominal interest rates. Prior to the Great Recession, the Federal Reserve had not encountered the zero lower bound in the modern post-war period. The zero lower bound represents a significant constraint monetary policy's ability to fully stabilize the economy. Unprecedented Use of Forward Guidance: Even though the Federal Reserve remains constrained by the zero lower bound, the monetary authority can still affect the economy through expectations about future nominal policy rates. By providing agents in the economy with forward guidance on the future path of policy rates, monetary policy can stimulate the economy even when current policy rates remain constrained. Throughout the Great Recession and the subsequent recovery, the Federal Reserve provided the economy with explicit statements about the future path of monetary policy. In particular, the central bank has discussed the timing and macroeconomic conditions necessary to begin raising its nominal policy rate. Using this policy tool, the Federal Reserve continues to respond to the state of the economy at the zero lower bound. Large Fiscal Expansion: During the Great Recession, the United States engaged in a very large program of government spending and tax reductions. The massive fiscal expansion was designed to raise national income and help mitigate the severe economic contraction. A common justification for the fiscal expansion is the reduced capacity of the monetary authority to stimulate the economy at the zero lower bound. Many economists argue that the benefits of increasing government spending are significantly higher when the monetary authority is constrained by the zero lower bound. The goal of this dissertation is to better understand how these various elements contributed to the macroeconomic outcomes during and after the Great Recession. In addition to understanding each of the elements above in isolation, a key component of this analysis focuses on the interaction between the above elements. A key unifying theme between all of the elements is the role in monetary policy. In modern models of the macroeconomy, the monetary authority is crucial in determining how a particular economic mechanism affects the macroeconomy. In the first and second chapters, I show that monetary policy plays a key role in offsetting the negative effects of increased uncertainty about the future. My third chapter highlights how assumptions about monetary policy can change the impact of various shocks and policy interventions. For example, suppose the fiscal authority wants to increase national output by increasing government spending. A key calculation in this situation is the fiscal multiplier, which is dollar increase in national income for each dollar of government spending. I show that fiscal multipliers are dramatically affected by the assumptions about monetary policy even if the monetary authority is constrained by the zero lower bound. The unique nature of the elements discussed above makes analyzing their contribution difficult using standard macroeconomic tools. The most popular method for analyzing dynamic, stochastic general equilibrium models of the macroeconomy relies on linearizing the model around its deterministic steady state and examining the local dynamics around that approximation. However, the nature of the unique elements above make it impossible to fully capture dynamics using local linearization methods. For example, the zero lower bound on nominal interest rates often occurs far from the deterministic steady state of the model. Therefore, linearization around the steady state cannot capture the dynamics associated with the zero lower bound. The overall goal of this dissertation is to use and develop tools in computational macroeconomics to help better understand the Great Recession. Each of the chapters outlined below examine at least one of the topics listed above and its impact in explaining the macroeconomics of the Great Recession. In particular, the essays highlight the role of the monetary authority in generating the observed macroeconomic outcomes over the past several years. Can increased uncertainty about the future cause a contraction in output and its components? In joint work with Susanto Basu, my first chapter examines the role of uncertainty shocks in a one-sector, representative-agent, dynamic, stochastic general-equilibrium model. When prices are flexible, uncertainty shocks are not capable of producing business-cycle comovements among key macroeconomic variables. With countercyclical markups through sticky prices, however, uncertainty shocks can generate fluctuations that are consistent with business cycles. Monetary policy usually plays a key role in offsetting the negative impact of uncertainty shocks. If the central bank is constrained by the zero lower bound, then monetary policy can no longer perform its usual stabilizing function and higher uncertainty has even more negative effects on the economy. We calibrate the size of uncertainty shocks using fluctuations in the VIX and find that increased uncertainty about the future may indeed have played a significant role in worsening the Great Recession, which is consistent with statements by policymakers, economists, and the financial press. In sole-authored work, the second chapter continues to explore the interactions between the zero lower bound and increased uncertainty about the future. From a positive perspective, the essay further shows why increased uncertainty about the future can reduce a central bank's ability to stabilize the economy. The inability to offset contractionary shocks at the zero lower bound endogenously generates downside risk for the economy. This increase in risk induces precautionary saving by households, which causes larger contractions in output and inflation and prolongs the zero lower bound episode. The essay also examines the normative implications of uncertainty and shows how monetary policy can attenuate the negative effects of higher uncertainty. When the economy faces significant uncertainty, optimal monetary policy implies further lowering real rates by committing to a higher price-level target. Under optimal policy, the monetary authority accepts higher inflation risk in the future to minimize downside risk when the economy hits the zero lower bound. In the face of large shocks, raising the central bank's inflation target can attenuate much of the downside risk posed by the zero lower bound. In my third chapter, I examine how assumptions about monetary policy affect the economy at the zero lower bound. Even when current policy rates are zero, I argue that assumptions regarding the future conduct of monetary policy are crucial in determining the effects of real fluctuations at the zero lower bound. Under standard Taylor (1993)-type policy rules, government spending multipliers are large, improvements in technology cause large contractions in output, and structural reforms that decrease firm market power are bad for the economy. However, these policy rules imply that the central bank stops responding to the economy at the zero lower bound. This assumption is inconsistent with recent statements and actions by monetary policymakers. If monetary policy endogenously responds to current economic conditions using expectations about future policy, then spending multipliers are much smaller and increases in technology and firm competitiveness remain expansionary. Thus, the model-implied benefits of higher government spending are highly sensitive to the specification of monetary policy. / Thesis (PhD) — Boston College, 2014. / Submitted to: Boston College.

Essays on Macroeconomics and Asset Pricing:Eiermann, Alexander January 2017 (has links)
Thesis advisor: Peter Ireland / A significant theoretical literature suggests that the effects of open market operations and large scale asset purchases are limited when short-term interest rates are constrained by the zero-lower-bound (ZLB). This view is supported by a growing body of empirical evidence that points to the tepid response of the U.S. economy to extraordinary policy measures implemented by the Federal Reserve (Fed) during the past several years. In the first essay, Effective Monetary Policy at the Zero-Lower-Bound, I show that permanent open market operations (POMOs), defined as financial market interventions that permanently increase the supply of money, remain relevant at the ZLB and can increase output and inflation. Consequently, I argue that the limited success of Fed policy in recent years may be due in part to the fact that it failed to generate sufficient money creation to support economic recovery following the Great Recession. I then demonstrate that conducting POMOs at the ZLB may improve welfare when compared to a broad range of policy regimes, and conclude by conducting a robustness exercise to illustrate that money creation remains relevant at the ZLB when it is not necessarily permanent. With these results in hand, I explore the consequences of Fed QE more directly in a framework asset purchases are an independent instrument of monetary policy. In the second essay, Effective Quantitative Easing at the Zero-Lower-Bound, I show that the observed lack of transmission between U.S. monetary policy and output economic activity a consequence of the fact the Fed engaged in what I define as sterilized QE: temporary asset purchases that have a limited effect on the money supply. Conversely, I show that asset purchase programs geared towards generating sustained increases in the money supply may significantly attenuate output and inflation losses associated with adverse economic shocks and the ZLB constraint. Furthermore, these equilibrium outcomes may be achieved with a smaller volume of asset purchases. My results imply that Fed asset purchase programs designed to offset the observed declines in the U.S. money supply could have been a more effective and efficient means of providing economic stimulus during the recovery from the Great Recession. The third essay—which is joint work with Apollon Fragkiskos, Harold Spilker, and Russ Wermers— titled Buyout Gold: MIDAS Estimators and Private Equity, we develop a new approach to study private equity returns using a data set first introduced in Fragkiskos et al. (2017). Our innovation is that we adopt a mixed data sampling (MIDAS) framework and model quarterly private equity returns as a function of high frequency factor prices. This approach allows us to endogenize time aggregation and use within-period information that may be relevant to pricing private equity returns in a single, parsimonious framework. We find that our MIDAS framework offers superior performance in terms of generating economically meaningful factor loadings and in-sample and out-of-sample fit using index and vintage-level returns when compared with other methods from the literature. Results using fund-level data are mixed, but MIDAS does display a slight edge. Concerning appropriate time-aggregation, we show that there is significant heterogeneity at the vintage level. This implies highly aggregated private equity data may not properly reflect underlying performance in the cross section.
