Monetary Aggregates, Asset Prices and Real Outcomes

Paying close attention to money, credit, and asset prices shall improve the IWH's macroeconomic policy work, especially in terms of forecasting macroeconomic developments and risks, but also in terms of assessing the stance of monetary policy. To this end, it is necessary to understand the relationship between monetary and financial developments, on the one hand, and macroeconomic dynamics and stability, on the other hand. Money and credit are important determinants of the macroeconomic performance of a market economy. Research in this group contributes to the literature on quantitative macroeconomic models to be applied for forecasting and policy analysis that incorporate monetary and financial aspects.

The Quantity Theory Revisited: A New Structural Approach

Makram El-Shagi Sebastian Giesen

in: Macroeconomic Dynamics, No. 1, 2015

Abstract

We propose a unified identification scheme to identify monetary shocks and track their propagation through the economy. We combine three approaches dealing with the consequences of monetary shocks. First, we adjust a state space version of the P-star type model employing money overhang as the driving force of inflation. Second, we identify the contemporaneous impact of monetary policy shocks by applying a sign restriction identification scheme to the reduced form given by the state space signal equations. Third, to ensure that our results are not distorted by the measurement error exhibited by the official monetary data, we employ the Divisia M4 monetary aggregate provided by the Center for Financial Stability. Our approach overcomes one of the major difficulties of previous models by using a data-driven identification of equilibrium velocity. Thus, we are able to show that a P-star model can fit U.S. data and money did indeed matter in the United States.

The Dynamics of Bank Spreads and Financial Structure

Reint E. Gropp C. Kok J.-D. Lichtenberger

in: Quarterly Journal of Finance, No. 4, 2014

Abstract

This paper investigates the effect of within banking sector competition and competition from financial markets on the dynamics of the transmission from monetary policy rates to retail bank interest rates in the euro area. We use a new dataset that permits analysis for disaggregated bank products. Using a difference-in-difference approach, we test whether development of financial markets and financial innovation speed up the pass through. We find that more developed markets for equity and corporate bonds result in a faster pass-through for those retail bank products directly competing with these markets. More developed markets for securitized assets and for interest rate derivatives also speed up the transmission. Further, we find relatively strong effects of competition within the banking sector across two different measures of competition. Overall, the evidence supports the idea that developed financial markets and competitive banking systems increase the effectiveness of monetary policy.

Toward a Taylor Rule for Fiscal Policy

Martin Kliem Alexander Kriwoluzky

in: Review of Economic Dynamics, No. 2, 2014

Abstract

In DSGE models, fiscal policy is typically described by simple rules in which tax rates respond to the level of output. We show that there is only weak empirical evidence in favor of such specifications in US data. Instead, the cyclical movements of labor and capital income tax rates are better described by a contemporaneous response to hours worked and investment, respectively. We show that conditioning on these variables is also desirable from a normative perspective as it significantly improves welfare relative to output-based rules.

Impact of Personal Economic Environment and Personality Factors on Individual Financial Decision Making

S. Prinz G. Gründer R. D. Hilgers Oliver Holtemöller I. Vernaleken

in: Frontiers in Decision Neuroscience, No. 158, 2014

Abstract

This study on healthy young male students aimed to enlighten the associations between an individual’s financial decision making and surrogate makers for environmental factors covering long-term financial socialization, the current financial security/responsibility, and the personal affinity to financial affairs as represented by parental income, funding situation, and field of study. A group of 150 male young healthy students underwent two versions of the Holt and Laury (2002) lottery paradigm (matrix and random sequential version). Their financial decision was mainly driven by the factor “source of funding”: students with strict performance control (grants, scholarships) had much higher rates of relative risk aversion (RRA) than subjects with support from family (ΔRRA = 0.22; p = 0.018). Personality scores only modestly affected the outcome. In an ANOVA, however, also the intelligence quotient significantly and relevantly contributed to the explanation of variance; the effects of parental income and the personality factors “agreeableness” and “openness” showed moderate to modest – but significant – effects. These findings suggest that environmental factors more than personality factors affect risk aversion.

Liquidity in the Liquidity Crisis: Evidence from Divisia Monetary Aggregates in Germany and the European Crisis Countries

Makram El-Shagi

in: Economics Bulletin, No. 1, 2014

Abstract

While there has been much discussion of the role of liquidity in the recent financial crises, there has been little discussion of the use of macroeconomic aggregation techniques to measure total liquidity available to the market. In this paper, we provide an approximation of the liquidity development in six Euro area countries from 2003 to 2013. We show that properly measured monetary aggregates contain significant information about liquidity risk.

Financial Technologies and the Effectiveness of Monetary Policy Transmission

Iftekhar Hasan Boreum Kwak Xiang Li

in: IWH Discussion Papers, No. 26, 2020

Abstract

This study investigates whether and how financial technologies (FinTech) influence the effectiveness of monetary policy transmission. We use an interacted panel vector autoregression model to explore how the effects of monetary policy shocks change with regional-level FinTech adoption. Results indicate that FinTech adoption generally mitigates monetary policy transmission to real GDP, consumer prices, bank loans, and housing prices. A subcategorical analysis shows that the muted transmission is the most pronounced in the adoption of FinTech payment and credit, compared to that of insurance. The regulatory arbitrage and competition between FinTech and banks are the possible mechanisms leading a mitigated monetary policy transmission.

Sovereign Default Risk, Macroeconomic Fluctuations and Monetary-Fiscal Stabilisation

Markus Kirchner Malte Rieth

in: IWH Discussion Papers, No. 22, 2020

Abstract

This paper examines the role of sovereign default beliefs for macroeconomic fluctuations and stabilisation policy in a small open economy where fiscal solvency is a critical problem. We set up and estimate a DSGE model on Turkish data and show that accounting for sovereign risk significantly improves the fit of the model through an endogenous amplication between default beliefs, exchange rate and inflation movements. We then use the estimated model to study the implications of sovereign risk for stability, fiscal and monetary policy, and their interaction. We find that a relatively strong fiscal feedback from deficits to taxes, some exchange rate targeting, or a monetary response to default premia are more effective and efficient stabilisation tools than hawkish inflation targeting.

Exchange Rates and the Information Channel of Monetary Policy

Oliver Holtemöller Alexander Kriwoluzky Boreum Kwak

in: IWH Discussion Papers, No. 17, 2020

Abstract

We disentangle the effects of monetary policy announcements on real economic variables into an interest rate shock component and a central bank information shock component. We identify both components using changes in interest rate futures and in exchange rates around monetary policy announcements. While the volatility of interest rate surprises declines around the Great Recession, the volatility of exchange rate changes increases. Making use of this heteroskedasticity, we estimate that a contractionary interest rate shock appreciates the dollar, increases the excess bond premium, and leads to a decline in prices and output, while a positive information shock appreciates the dollar, decreases prices and the excess bond premium, and increases output.

The Evolution of Monetary Policy in Latin American Economies: Responsiveness to Inflation under Different Degrees of Credibility

Stefan Gießler

in: IWH Discussion Papers, No. 9, 2020

Abstract

This paper investigates the forward-lookingness of monetary policy related to stabilising inflation over time under different degrees of central bank credibility in the four largest Latin American economies, which experienced a different transition path to the full-fledged inflation targeting regime. The analysis is based on an interest rate-based hybrid monetary policy rule with time-varying coefficients, which captures possible shifts from a backward-looking to a forward-looking monetary policy rule related to inflation stabilisation. The main results show that monetary policy is fully forward-looking and exclusively reacts to expected inflation under nearly perfect central bank credibility. Under a partially credible central bank, monetary policy is both backward-looking and forward-looking in terms of stabilising inflation. Moreover, monetary authorities put increasingly more priority on stabilising expected inflation relative to actual inflation if central bank credibility tends to improve over time.

Why is Unemployment so Countercyclical?

Lawrence J. Christiano Martin S. Eichenbaum Mathias Trabandt

in: NBER Working Paper No. 26723, 2020

Abstract

We argue that wage inertia plays a pivotal role in allowing empirically plausible variants of the standard search and matching model to account for the large countercyclical response of unemployment to shocks.
