Price rules, wage indexing, and optimal monetary policy

There has been a recent increased interest in a monetary price rule. This paper analyzes the efficiency of such a monetary rule within the context of a rational expectations macro model. We compare the price rule with the standard money rule and interest rate rule. We find that as the supply shock variance approaches zero the price rule dominates both a money and interest rate rule. We then investigate the efficiency of these alternative money rules when we allow wage indexation to the price level.     

Unique monetary equilibria with interest rate rules: An extension

In a recent paper, Adão et al. (2011), using a cash-in-advance framework, derive an interest rate rule that results in a unique monetary equilibrium. The resulting interest rate rule is forward looking and the interest rate responds positively to forecasts of future real activity and to forecasts of the future price level. This paper extends their approach to a transactions cost environment. The resulting interest rate rule has the added feature that, in line with previous studies, the nominal interest rate responds positively to forecasts of future inflation.     

价格型货币政策操作框架：利率走廊的 条件、机制与实现*

随着商业银行产权市场化水平的提高,以及金融创新的不断涌现,数量型货币政策操作框架的有效性开始下降。本文通过对商业银行行为的分析,基于其极大化经营利润的诉求,论证了利率走廊系统的运行条件及机制。研究认为,完善的制度安排、商业银行的市场主体地位、充分竞争的市场、高效的实时清算系统等是利率走廊系统发挥作用的基础条件;在利率走廊系统运行过程中,当货币市场被注入过多流动性时,其可能转化成地板系统;价格型货币政策操作框架能够实现分别进行资金价格调控与资金数量调控,从而使货币政策操作的针对性与有效性得到提高。由此论文从利率走廊系统的构建、中央银行的职责、商业银行的行为等方面,提出我国货币政策操作框架从数量型调控向价格型调控转型的路径。     

Does wage-inflation targeting complement foreign exchange intervention? An evaluation of a multi-target,two-instrument monetary policy framework

We assess the inclusion of wage inflation as an intermediate target of an emerging central bank using a dynamic stochastic general equilibrium model with sticky wages and prices calibrated for the South Korean economy. The model includes wage inflation as an additional target jointly with domestic price inflation and the output gap in a Taylor- type interest rate rule operating with a sterilized foreign exchange (FX) intervention rule. Our results show a complementary relationship between wage inflation targeting and price inflation targeting. That is, by supplementing price inflation targeting with wage inflation targeting, welfare improves for cases with and without sterilized FX intervention. When intervention is in place, wage inflation targeting has the added advantage of reducing the volatilities of nominal exchange rate and foreign exchange reserves thereby promoting a more sustainable conduct of FX intervention.     

Behavioral rules and sequences of macroequilibria

This paper compares the dynamic consequences of several diferent behavioral rules involving price or quantity adjustments in a temporary equilibrium, macroeconomic framework. The central rule studied is the widely practiced, cost mark-up, administered pricing rule. A competitive, quantity adjustment rule based on a target rate of return is also examined. These are contrasted with monopolistic, profit maximizing price and quantity adjusting rules. Although the analysis represents but an initial foray into the territory where the interests of behavioral and macroeconomic theories overlap, the results, which trace stagflation to instabilities in ‘permanent’, full-employment equilibrium, suggest that further work in this direction may improve our understanding of present inflationary phenomena.     

The role of the exchange rate in Canadian monetary policy: evidence from a TVP-BVAR model

A time-varying parameters Bayesian structural vector autoregression (TVP-BVAR) model with stochastic volatility is employed to characterize the monetary policy stance of the Bank of Canada (BoC) in terms of an interest rate rule linking the policy rate to the output gap, inflation and the exchange rate. Using quarterly bilateral Canadian–US data, we find such an interest rate rule to have little explanatory power for the early part of our sample starting in the mid-1980s, but to become more suitable to explain interest rate dynamics from the mid-1990s onwards. Whereas the exchange rate turns out to be the major determinant of the policy rate in the 1980s, its importance declines throughout the 1990s and 2000s, although it continues to be influential even towards the end of the sample period ending in 2015Q2. We also find interest rate shocks to have become more effective in influencing the macroeconomy over time, indicating that the BoC has continually gained monetary policy credibility. We associate this development with the BoC successively de-emphasizing the role of the exchange rate in informing interest rate decisions, thereby alleviating the potential monetary policy conflict between targeting the exchange rate and maintaining the price stability goal.     

The effects of monetary policy in a small open economy: the case of Portugal

In this article, I analyse the macroeconomic effects of monetary policy on the Portuguese economy. I show that a positive interest rate shock leads to: (i) a contraction of real GDP and a substantial increase of the unemployment rate; (ii) a quick fall in the commodity price and a gradual decrease of the price level and (iii) a downward correction of the stock price index. It also produces a ‘short-lived liquidity effect’ and helps explain the negative comovement between bonds and stocks. In addition, I find evidence suggesting the existence of a money demand function characterized by small output and interest rate elasticities. By its turn, the central bank’s policy rule follows closely the dynamics of the money markets. Finally, both the real GDP and the price level in Portugal would have been higher during almost the entire sample period if there were no monetary policy surprises.     

Impact of asset price fluctuation on China’s monetary policy: An empirical analysis based on quarterly data, 1994–2006

The strenuous fluctuation in global asset price in recent years has had a profound impact on the economic and social development of every country. An empirical analysis indicates that asset prices (the stock price index and real estate prices) are important endogenous variables affecting the interest rate reaction function of central bank monetary policy. With expected inflation as a given, each one percentage point rise in output gap will cause a 0.79 percentage point reduction in interest rates by the central bank and each one percentage point rise in real estate price will result in a 2.2 percentage point rise in interest rates. The stock price index does have an influence on the trends in monetary policy, but it is less salient than the impact of housing prices. We also show that monetary policy that employs asset price as an endogenous variable increases the central bank’s control in seeking to attain its objectives. Therefore we suggest that the central bank should make asset price fluctuation an endogenous variable and incorporate it into its forward-looking interest rate rule, in order to facilitate the healthy development of China’s markets for real estate, stocks and derivatives, energy and bulk commodities and maintain rapid, smooth, sustainable and harmonious economic development.     

Optimal interest rate rule in a DSGE model with housing market spillovers

This paper studies the optimal interest rate rule in a DSGE model with housing market spillovers (Iacoviello and Neri, 2010). We find that the optimal rule responds to house price inflation even when the stabilization of house price is not among the objectives of the policymaker, and that the strength of the response depends crucially on a few structural parameters.     

A comparison of optimal policy rules prior to and during inflation targeting: empirical evidence from Bank of Canada

We examine policy rules that are consistent with inflation targeting (IT) framework in a small macroeconomic model of the Canadian economy. We set up an optimal linear regulator problem and derive policy rules to compare the dynamics of pre-IT and IT eras. We find that while the optimal monetary policy rule in the pre-IT period is best described with a loss function that attaches equal weight to price stability, financial stability and output stability; the IT era is dominated by the price stability objective followed by the financial stability and output stability, consecutively. Moreover, we do not find an explicit role for exchange rate stability in the objective function of the Bank of Canada for both monetary policy eras. We, then, compare the properties of the derived optimal rules with those of an ad hoc Taylor rule for the IT period. In response to inflationary shocks, Taylor rule brings down inflation rates more quickly compared to the derived policy rules, but at the cost of a higher sacrifice ratio and more volatile interest rates.     

Investment and interest rate policy: a discrete time analysis

This paper analyzes the restrictions necessary to ensure that the interest rate policy rule used by the central bank does not introduce local real indeterminacy into the economy. It conducts the analysis in a Calvo-style sticky price model. A key innovation is to add investment spending to the analysis. In this environment, local real indeterminacy is much more likely. In particular, all forward-looking interest rate rules are subject to real indeterminacy.     

ENDOGENOUS TIME PREFERENCE,INTEREST‐RATE RULES,AND INDETERMINACY*

This paper extends the Benhabib et al. flexible‐price, money‐in‐the‐utility‐function model by considering endogenous time preference and re‐examines equilibrium indeterminacy in response to alternative interest‐rate rules. We show that either an active or a passive interest‐rate feedback rule can generate local indeterminacy even if consumption and real money balances are Edgeworth independent. This result is in sharp contrast to that in the related literature. We also find that in the presence of endogenous time preference, local indeterminacy may occur regardless of whether the monetary policy is based on the interest‐rate feedback rule or money growth‐rate targeting.     

Professor Fisher and the quantity theory – a significant encounter

Abstract

Irving Fisher's encounter with the Quantity Theory of Money began in the 1890s, during the debate about bimetallism, and reached its high point in 1911 with the publication of The Purchasing Power of Money. His most important refinement of the theory, derived from his recognition of bank deposits as means of exchange, was to treat their out of equilibrium recursive interaction with inflation as integral to it. This treatment underlay both his 1920s work on the business cycle as a “dance of the dollar” and his advocacy of subjecting monetary policy to a legislated price stability rule, initially to be based on his “compensated dollar” scheme. Fisher's failure to recognise the onset of the Great Depression even as it was happening was directly related to his faith in the quantity theory's seeming implication that price level stability in and of itself guaranteed the continuation of prosperity, while his subsequent work on the debt deflation theory of great depressions initially failed to repair the damage that this failure did to his reputation, and to that of the quantity theory. In the 1930s Fisher nevertheless remained an active supporter of various schemes to reflate and then stabilise the price level. His subsequent influence on the quantity theory based Monetarist counter-revolution that began in the 1950s lay, directly, in its deployment of his analysis of expected inflation on nominal interest rates, and, indirectly, in its espousal of the case for subjecting monetary policy to a legislated rule.     

MONETARY POLICY DURING JAPAN'S LOST DECADE*

We develop a quantitative costly price adjustment model with capital formation for the Japanese economy. The model respects the zero interest rate bound and is calibrated to reproduce the nominal and real facts from the 1990s. We use the model to investigate the properties of alternative monetary policies during this period. The setting of the long‐run nominal interest rate in a Taylor rule is much more important for avoiding the zero bound than the setting of the reaction coefficients. A long‐run interest rate target of 2.3% during the 1990s avoids the zero bound and enhances welfare.     

TAYLOR RULE REACTION COEFFICIENTS AND REAL EXCHANGE RATE PERSISTENCE

Recent literature has established a link between the persistence of real exchange rates and the degree of inertia in Taylor rule monetary policy reactions functions. This paper provides a different view on this link by investigating how the size of Taylor rule reaction coefficients impacts the adjustment dynamics of the real exchange rate. Within a stylized sticky‐price open‐economy macro model, it is demonstrated that a stronger interest rate reaction to inflation in the Taylor rule raises the convergence speed of the real exchange rate. Conversely, raising the coefficient on the output gap or attending to the exchange rate in an open‐economy version of the Taylor rule slows down real exchange rate adjustment. In all cases, more rapid convergence comes at the cost of stronger initial real exchange rate misalignments in the wake of monetary policy shocks.     

房地产价格、泰勒规则与宏观经济调控——基于2000-2010年我国宏观经济数据的检验

央行是否应该针对房地产价格制定货币政策进行调控,一直是学者们关注的焦点,但研究结果仍存在分歧。基于2000-2010年我国季度经济数据,对比检验了融入房地产价格的泰勒规则与标准泰勒规则对我国制定货币政策调控宏观经济的适用性。实证结果表明,依据标准泰勒规则所制定的利率政策,可以降低央行损失函数值,提高利率政策有效性。这一结果意味着,在房地产价格波动不影响物价稳定和经济增长的情况下,央行不应针对房地产价格进行调控。也就是说,央行需考虑房地产价格波动与通货膨胀和产出之间的相关关系,判断其对政策目标的潜在影响,制定利率政策对宏观经济进行调控。     

Pricing Access to a Monopoly Input

What price should downstream entrants pay a vertically integrated incumbent monopoly for use of its assets? Courts, legislators, and regulators have at times mandated that incumbent monopolies lease assets required for the production of a retail service to entrants in efforts to increase the competitiveness of retail markets. This paper compares two rules for pricing such monopoly inputs: marginal cost pricing (MCP) and generalized efficient component pricing rule (GECPR). The GECPR is not a fixed price, but is a rule that determines the input price to be paid by the entrant from the entrant's retail price. Comparing the retail market equilibrium under MCP and GECPR, the GECPR leads to lower equilibrium retail prices. If the incumbent is less efficient than the entrant, the GECPR also leads to lower production costs than does the MCP rule. If the incumbent is more efficient than the entrant, however, conditions may exist in which MCP leads to lower production costs than does the GECPR. The analysis is carried out assuming either Bertrand competition, quantity competition, or monopolistic competition between the incumbent and entrant in the downstream market.     

The pricing of a metal output obtained from multigrade ore deposits

The distinction between ore throughput and metal output through the geological ‘tonnage–grade’ relationship is of utmost importance for the characterization of the optimal ore extraction and metal price time profile. It is shown that although ore extraction is costly, the metal price rises at the interest rate during the phase of simultaneous extraction of varying-grade ore. Moreover, while the total quantity of ore is extracted at a time-increasing rate, the lower-grade ore (higher-grade) is extracted at a time-decreasing (-increasing) rate.     

Can product differentiation mitigate conflicts of interest between principal stakeholders? A cournot-bertrand comparison

This paper aims to investigate the impact of product differentiation on the extent of conflict of interest between principal stakeholders (shareholders, employees, and consumers), which is one of the most important concerns of stakeholder-oriented corporate governance. We consider a differentiated duopoly competing either in price or quantity after the wages of employees are negotiated with a labor union. We find that price competition and quantity competition have drastically different implications on whether product differentiation mitigates stakeholders' conflicts. Specifically, product differentiation can mitigate stakeholders' conflicts when firms compete in price, but not when they compete in quantity. Therefore, the product differentiation effect in mitigating stakeholders' conflicts differs across markets characterized by price competition versus quantity competition.     

Adjustment Costs,Inventories and Output

This paper analyzes the optimal adjustment strategy of an inventory‐holding firm facing price‐ and quantity‐adjustment costs in an inflationary environment. The model nests both the original menu‐cost model that allows production to be costlessly adjusted, and the later model that includes price‐ and quantity‐adjustment costs, but rules out inventory holdings. It is shown that the firm's optimal adjustment strategy may involve stockouts. At low inflation rates, output is inversely related to the inflation rate, and the length of time demand is satisfied increases with the demand elasticity but decreases with the storage cost and the real interest rate.
