The effects of monetary policy in Russia: A factor-augmented VAR approach

Using factor-augmented vector autoregressive (FAVAR) models, this study examines the effects of the Central Bank of Russia’s (CBR) monetary policy on economic indicators. The sample includes 39 monthly macroeconomic series and covers the period 2004 through 2019. The analysis revealed counter-intuitive results, with consumer prices often responding positively to a contractionary monetary policy shock, and vice versa; this is related to the impossible trinity. The ruble exchange devaluation was accompanied by price increases through an import price pass-through, so the CBR chose exchange stability and free capital flows out of the impossible trinity, temporarily subordinating monetary policy independence. Such independence was limited, possibly due to Russia’s high dependence on energy exports and the link between energy prices and the exchange rate. The findings indicate no direct evidence of an effect of monetary policy tightening on the decrease in consumer prices; rather, the attenuation of ruble depreciation may have helped to stabilize prices, even after the CBR adopted inflation targeting.     

Decomposing the effects of monetary policy using an external instruments SVAR

We study the effects of monetary policy on economic activity separately identifying the effects of a conventional change in the fed funds rate from the policy of forward guidance. We use a structural VAR identified using external instruments from futures market data. The response of output to a fed funds rate shock is found to be consistent with typical monetary VAR analyses. However, the effect of a forward guidance shock that increases long‐term interest rates has an expansionary effect on output. This counterintuitive response is shown to be tied to the asymmetric information between the Federal Reserve and the public.     

Modeling monetary policy as an unobserved variable

This paper presents a model of the U.S. Monetary Authority. It is assumed that monetary policy is a single dimensioned unobserved variable that links changes in a set of ‘causal’ variables representing economic goals and changes in money market ‘indicator’ variables. Several issues are examined pertaining to the weights attached to the causal variables including: the lag structure, changes over time, and asymmetric effects of positive and negative changes. As a by product of the model, the paper presents an estimated index of monetary policy for the years 1955–1975.     

Optimal fiscal and monetary policy with occasionally binding zero bound constraints

This paper studies optimal fiscal and monetary policy when the nominal interest rate is subject to the zero lower bound (ZLB) constraint in a stochastic New Keynesian economy. In the baseline model calibrated to match key features of the U.S. economy, it is optimal for the government to increase its spending when at the ZLB in the stochastic environment by about 60 percent more than it would in the deterministic environment. The presence of uncertainty creates a unique time-consistency problem if the steady state is inefficient. Although access to government spending policy increases welfare in the face of a large deflationary shock, it decreases welfare during normal times as the government reduces the nominal interest rate less aggressively before reaching the ZLB.     

Optimal monetary policy rules,financial amplification,and uncertain business cycles

This paper studies optimal monetary policy in the presence of ‘uncertainty’, time-variation in cross-sectional dispersion of firms׳ productive performance. Using a model with financial market imperfections, the results suggest that (i) optimal policy is to dampen the strength of financial amplification by responding to uncertainty (at the expense of creating mild degree of fluctuations in inflation). (ii) Higher uncertainty makes the welfare-maximizing planner more willing to relax financial constraints. (iii) Credit spreads are a good proxy for uncertainty. Hence, a non-negligible response to credit spreads – together with a strong anti-inflationary policy stance – achieves the highest aggregate welfare possible.     

Designing monetary policy committees

We integrate monetary policy-making by committee into a New Keynesian model to assess the consequences of the committee׳s institutional characteristics for inflation, output, and welfare. Our analysis delivers the following results. First, we demonstrate that transparency about the committee׳s future composition is typically harmful. Second, we show that short terms for central bankers lead to effective inflation stabilization at the expense of comparably high output variability. Third, larger committees generally allow for more efficient stabilization of inflation but possibly for less efficient output stabilization. Fourth, large committees and short terms are therefore socially desirable if the weight on output stabilization in the social loss function is low. Fifth, we show that a central banker with random preferences may be preferable to a central banker who shares the preferences of society.     

Optimal monetary policy under incomplete markets and aggregate uncertainty: A long-run perspective

This paper examines the role of monetary policy in an environment with aggregate risk and incomplete markets. In a two-period overlapping-generations model with aggregate uncertainty, optimal monetary policy attains the ex-ante Pareto optimal allocation. This policy aims to stabilize the savings rate in the economy by changing real returns of nominal bonds via variation in expected inflation. Optimal expected inflation is procylical and on average higher than without uncertainty. Simple inflation targeting rules closely approximate the optimal monetary policy.     

Supervisory frameworks and monetary policy

One issue that the crisis has pushed to the forefront is the relationship between macroeconomics and finance, and how we think about the footings of financial stability. My comments this evening will focus briefly on this intersection of monetary policy and supervisory and regulatory issues. I am convinced that promoting financial stability requires a comprehensive approach that uses both macroprudential tools and the examination of individual firms, relying on the judgment of experienced examiners. In addition, I am skeptical of a clean “separation principle” that places financial stability squarely in the purview of the supervisors. Instead, I think monetary policymakers also need to maintain a careful eye on the financial system and how interest rate policy affects incentives for financial markets and institutions.     

Optimal monetary policy in a new Keynesian model with animal spirits and financial markets

This article presents a macro-finance-interaction model that integrates a NKM with bounded rationality and an agent-based financial market model. We derive four interactive channels between the two sectors where two channels are strictly microfounded. We analyze the impact of the different channels on economic stability and derive optimal (conventional and unconventional) monetary policy rules. We find that coefficients of optimal Taylor rules do not significantly change if financial market stabilization becomes part of the central bank׳s objective function. Additionally, we show that rule-based, backward-looking monetary policy creates huge instabilities if expectations are boundedly rational. Our model is externally validated by showing that it generates fat tailed output growth rates.     

Delegating optimal monetary policy inertia

In a forward-looking business cycle model, central banks can achieve the (timeless)optimal commitment equilibrium even in the absence of a commitment technology, if they are delegated with an objective function that is different from the societal one. The paper develops a general linear-quadratic method to solve for the optimal delegation parameters that generate the optimal amount of inertia in a Markov-perfect equilibrium, and studies the optimal design of some policy regimes that are nested within this framework: the (squared) optimal targeting rule; inflation, output-gap growth and nominal income growth targeting; and inflation and output-gap contracts.     

Debt constraints and monetary policy

In the present paper we show how simple monetary policies can mitigate real effects of credit frictions. We consider stationary overlapping generations economies in which consumers are not equally efficient in producing capital and cannot commit to repay loans. The presence of money in itself does not mitigate the real effects of credit frictions. Equilibrium allocations are generally not Pareto optimal unless the returns on money and capital production are identical for more productive consumers. However, printing money and distributing it to young consumers increase their incomes allowing young more productive consumers to produce more capital. Consequently money printing increases output.     

Real-time data and monetary policy

This paper provides an introduction to the problems and opportunities provided by the availability of real-time data. We stress the importance of analyzing policy issues relying on real-time data. A summary of papers presented at a Conference hosted by the Bundesbank in 2004 is also provided.     

Combining monetary policy and prudential regulation: an agent-based modeling approach

This paper explores the interaction between monetary policy and prudential regulation in an agent-based modeling framework. Firms borrow funds from the banking system in an economy regulated by a central bank. The central bank carries out monetary policy, by setting the interest rate, and prudential regulation, by establishing the banking capital requirement. Different combinations of interest rate rule and capital requirement rule are evaluated with respect to both macroeconomic and financial stability. Several relevant policy implications were drawn. First, the efficacy of a given capital requirement rule or interest rate rule depends on the specification of the rule of the other type it is combined with. More precisely, less aggressive interest rate rules perform better when the range of variation of the capital requirement is narrower. Second, interest rate smoothing is more effective than the other interest rate rules assessed, as it outperforms those other rules with respect to financial stability and macroeconomic stability. Third, there is no tradeoff between financial and macroeconomic stability associated with a variation of either the capital requirement or the smoothing interest rate parameter. Finally, our results reinforce the cautionary finding of other studies regarding how output can be ravaged by a low inflation targeting.
