This work presents a model of a two-period economy to discuss the link between the precautionary motivation for holding international reserves and the country's monetary policy concerns due to a crisis.

There are two possible states of nature in the second period of the economy: a normal state and a crisis state. These states of nature represent uncertainty to the policy maker and he can insure against a crisis. The household has a constant-elasticity-of-substitution (CES) utility function, where utility depends on consumption and money.

By allowing money in the utility function and in the household financial constraint and considering that the objective of the central bank is to smooth inflation, it is concluded that monetary policy plays a role in the precautionary motivation of holding international reserves.

The model can be used to calculate optimal reserves holdings in its complete or even in its simplified version. Furthermore, it is possible to evaluate the impact of the intra-temporal substitution elasticity between consumption and real money in the decision of accumulating international reserves.

Higher intra-temporal substitution elasticities implies in more insurance via international reserves, and this discussion is not found in the existent literature on international reserves.

The objective of this study is to assess the impact of financial development (FD) on monetary policy efficiency (MPE) in developed G7 countries in the period 1980–2017, based on data availability.

This study followed a two-step process as follows: (1) using the Monte Carlo simulation based on Taylor curve theory to build the MPE measure and (2) evaluating the effect of FD on MPE by feasible generalized least squares (FGLS) estimation.

The results of this study show that (1) MPE varies over time. Monetary policy appears ineffective during the crisis period and is subject to many impacts of domestic and external shocks. On the contrary, the ability to influence the economy to achieve the central bank's goal tends to increase in the recovery stages, and this is in line with the actual. (2) FD has a negative impact on MPE. Interestingly, when considering the role of component FD indicators, the development of financial markets (FMs) has a negative impact on MPE while the development of financial institutions (FIs) has a positive impact. In particular, the impact of FI on MPE is mainly attributed to the impact of the depth of FI. Meanwhile, the impact of FM on MPE is mainly due to the impact of the efficiency in the FM.

To the author’s knowledge, this is the first study that evaluates the impact of FD on MPE in the context of measuring MPE by using the Taylor curve theory. Results from this study suggest a scientific and practical MPE measure and provide significant policy implications. This paper also offers suggestions for future research.

The global financial crisis demonstrated that monetary policy alone cannot ensure both price and financial stability. According to the Tinbergen (1952) rule, there was a gap in the policymakers’ toolkit for safeguarding financial stability, as the number of available policy instruments was insufficient relative to the number of policy objectives. That gap is now being closed through the creation of new macroprudential policy instruments. Both monetary policy and macroprudential policy have the capacity to influence both price and financial stability objectives. This paper develops a framework for determining how best to assign instruments to objectives.

Using a simplified New-Keynesian model, the authors examine two sets of policy trade-offs, the first concerning the relative effectiveness of monetary and macroprudential policy instruments in achieving price and financial stability objectives and the second concerning trade-offs between macroprudential policy instruments themselves.

This model shows that regardless of whether the objective is to enhance financial system resilience or to moderate the financial cycle, macroprudential policies are more effective than monetary policy. Likewise, monetary policy is more effective than macroprudential policy in achieving price stability. According to the Mundell (1962) principle of effective market classification, this implies that macroprudential policy instruments should be paired with financial stability objectives, and monetary policy instruments should be paired with the price stability objective. The authors also find a trade-off between the two sets of macroprudential policy instruments, which indicates that failure to moderate the financial cycle would require greater financial system resilience.

The main contribution of the paper is to establish – with the help of a model framework – the relative effectiveness of monetary and macroprudential policies in achieving price and financial stability objectives. By so doing, it provides a rationale for macroprudential policy and it shows how macroprudential policy can unburden monetary policy in leaning against the wind of financial imbalances.

When sectoral shocks hit a large, regionally heterogeneous economy, it is likely that regions with sectoral specialization will be affected in different ways. In these cases, it might be optimal for the country to decentralize the currency into a number of regional currencies, thus allowing for differentiated monetary policy. The paper aims to discuss these issues.

The author explicates the potential benefits and costs to decentralization. The author also highlights characteristics that should be satisfied in order to consider multiple currencies. This paper uses a theoretical and empirical model to test if the USA contains regional optimal currency areas. The author tests five potential divisions of the states into monetary subunions.

One of these divisions is proven to result in higher welfare (a 2 percent increase) than the status quo national monetary union. Thus, the USA is not an optimal currency area, and monetary decentralization could be a feasible and welfare-improving option for future policy.

There have been no previous studies of monetary divisions. Given the importance of fiscal decentralization, it is important to also understand the implications of monetary decentralization.

The purpose of this paper is to discuss the potential benefits of monetary policy rules for transition economies (TEs).

The paper discusses monetary policy rules, inflation targeting, political risk and ambiguity and monetary policy and ambiguity.

It is argued that the nominal interest rate may fail to be the appropriate instrument in such rules. One reason is the amount of non‐calculable political and economic risk inherent in TEs. These risks lead to a significant and volatile‐ambiguity premium in the interest rate over and above the normal risk premium, which makes the real equilibrium interest rate difficult to measure. Furthermore, ambiguity of the public regarding the monetary policy leads to an ambiguity premium on inflation.

The paper advocates a simple monetary policy rule based on a monetary aggregate like the money base minimizes the impact of ambiguity. It may therefore be the appropriate monetary policy for TEs.

This paper aims to investigate the existing relations between the management of public bonds on the dynamics of debt, term structure of interest rates and economic cycle, through a dynamic stochastic general equilibrium model (DSGE), which was estimated through Bayesian inference techniques using data from Brazil.

The model developed was used to investigate the effects of the public debt average maturity management when the economy faces a monetary policy shock. For this, three management scenarios are evaluated, including Brazilian securities average term.

Contrary to what might be inferred from DSGE models that limited the analysis of the debt term by imposing only one-period bonds, a contractionary monetary policy shock does not necessarily cause public debt to increase significantly. Debt term structure plays a crucial role in this result since the government does not need to roll the debt over at higher costs when the debt term profile is longer, reducing the debt service costs and then the impact on the overall debt.

Despite the relevance of this theme and its implications for the dynamics of the economy, there is still a gap to be filled in the literature when using DSGE models, since most part of the work that used this methodology limited the analysis of the debt term by imposing that government issues only one-period bonds. This paper differs from the others insofar as it promotes an investigation focused on the role played by debt maturity management on the performance of the contractionary monetary policy. This approach can generate a better understanding of debt management policy and its interaction with fiscal and monetary policies.

The purpose of this paper is to evaluate the performance of six types of policy rules applied for Indonesia, using monthly data spanning January 1980 to December 2008.

This paper uses deterministic simulations on a small macro model and evaluates the policy rules based on the loss function.

Among six types of policy rules, an inflation forecast‐based rule with contemporaneous output gap (IFBG) is found to be the most efficient rule for Indonesia. The rule suggests that the central bank should react strongly to inflation deviations from the target, react moderately to the output gap and smooth the interest rate. The optimal horizon is 3‐4 quarters. Including the exchange rate in the policy rule causes deterioration in economic performance.

No previous study examines Indonesia employing the same methodology.
