Abstract. Starting from the quantity theory of money we analyse the dynamic relationships between money, real output and prices for an unbalanced panel of 110 economies. Complementary to trivariate analyses we also adopt a P-star model explaining inflation via an equilibrium price level (P-star), which in turn depends on potential output and money. A key issue of the paper is the cross-sectional stability of estimation and inference results. We find cointegration among the considered variables. Particularly for high inflation countries homogeneity between prices and money cannot be rejected. Given homogeneity we find evidence for an error-correction mechanism linking current price changes and the lagged price gap. Parameter estimates indicating the adjustment towards the price equilibrium are larger in absolute value for high inflation countries. The latter results indicate that central banks, even in high inflation countries, can improve price stability by controlling monetary growth. 相似文献

This paper derives stylised facts on sectoral inflation dynamics and confronts these facts with two popular theoretical models of price setting. Based on sectoral price responses to macroeconomic shocks estimated from an approximate factor model, we find that the frequency of price changes explains a relevant share of the cross-sectional variation of the speed and size of responses. Moreover, there is little evidence that the volatility of sectoral inflation due to idiosyncratic shocks dampens the size and speed of the responses to macroeconomic shocks. These findings support a multi-sector model with sticky prices rather than a rational-inattention model. We derive the results from different modelling and sampling decisions proposed in the literature, and we find that the explanatory power of the frequency of price changes for the speed of response to a macroeconomic shock proves robust in the face of these decisions. Other results are sensitive with respect to the choice of the factor model and the treatment of outliers. 相似文献

We use a broad set of China’s macroeconomic indicators and a dynamic factor model to estimate latent factors of economic output and inflation, which are used to measure the ultimate objectives of monetary policy. The above factors and policy variables are incorporated into a TVP-SV-FAVAR model to investigate the dynamic effectiveness of Chinese monetary policy. Our results confirm that the effects of Chinese monetary policy are time-varying. By comparing the quantity rule with the price rule, we find that the price rule is more effective in managing China’s macro-economy, especially after the financial crisis. Moreover, the results can be regarded as a division of policy rules in a way that different rules are directed at different objectives. 相似文献

The debate over the Stability and Growth Pact (SGP) as a part of European Monetary Union, has highlighted the need to assess the extent to which fiscal policies of union members should be constrained as a pre-requisite for price stability within the union. In this paper, we develop a two country open economy model, where each country has overlapping generations of finitely lived consumers who supply labour to imperfectly competitive firms which can only change their prices infrequently. We examine the case where the two countries have formed a monetary union, but where the fiscal authorities remain independent. We show that the fiscal response required to ensure stability of the real debt stock is greater when consumers are not infinitely lived. In principle, this allows for some compensating behaviour between governments, but we show that the scope for compensation is limited. The monetary authority can abandon its active targeting of inflation to stabilise the debt of at most one fiscal authority, and any other combination of policies will either result in price level indeterminacy and/or indefinite transfers of wealth between the two economies. Finally, in a series of simulations we show that fiscal shocks have limited impact on output and inflation provided the fiscal authorities meet the (weak) requirements of fiscal solvency. However, when monetary policy is forced to abandon its active targeting of inflation, then fiscal shocks have a much greater impact on both output and inflation. 相似文献

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. 相似文献

I investigate the optimal monetary policy in a New Keynesian macroeconomic framework with the sticky information model of price adjustment. The model is solved for optimal policy, and welfare implications of three alternative monetary policy regimes under this optimal policy are compared when there is a cost‐push shock to the economy. These monetary policy regimes are the unconstrained policy, price‐level targeting and inflation targeting regimes. The results illustrate that optimal policy depends on the degree of price stickiness and the persistence of the shock. Inflation targeting emerges as the optimal policy if prices are flexible enough or the shock is persistent enough. However, the unconstrained policy or price‐level targeting might be preferable to inflation targeting if prices are not very flexible and the shock is not very persistent. The results also show that as prices become more flexible, the welfare loss usually gets bigger. 相似文献

We document producer price adjustment using a low‐inflation micro price dataset. On average 24% of prices adjust each month, with an average increase/decrease of 6%. Producer prices adjust more frequently than consumer prices, but their size of adjustment is typically smaller. Sectoral heterogeneity in the frequency of price adjustment is strongly related to heterogeneity in the cost structure. Fluctuations in aggregate producer price inflation occur to a large extent through variation in the relative share of upward and downward price adjustment. 相似文献

Daily price co-movement across different commodity classes and its key determinant are investigated in this paper. Using co-integration and Granger causality analysis, we identify a common liquidity factor which drives prices of five commodities (oil, silver, gold, corn, live cattle) to move along a common trend. When the market becomes more (less) liquid, all commodity prices tend to move up (down) in the same direction. As a result, such liquidity-driven price co-movement across different commodity classes is likely to generate aggregate price shocks and amplify inflation volatility. As a practical implication of our findings, policy makers ought to be able to draw valuable lessons from monitoring daily commodity liquidity dynamics as a timely bellwether for incipient inflation and to more effectively control inflation risk. 相似文献

This article examines asymmetric size- and sign-dependent effects of the output gap on the US quarterly inflation rate using data from the last half a century (1959Q2–2013Q1). Consistent with previous studies, it is found that the consumer price index is cointegrated with the unit labour cost and the price of oil. A short-run dynamic model is then estimated in which variations in the output gap are divided into three groups: large-positive; large-negative; and small-medium positive/negative. The results provide convincing evidence that only sufficiently large (positive or negative) variations of the output gap can significantly influence inflation. Put otherwise, relatively small to medium changes in the output gap exert no significant impact on inflation and if not separated, they can somewhat obscure the significant effects associated with large variations of the output gap. This study can lead to greater consensus on the inflation–output gap nexus. The findings remain robust despite the use of different measures of output gap and they are consistent with the modern doctrine but with a new caveat: inflation responds to both positive and negative changes in the output gap as long as such variations are of sizable magnitudes. 相似文献

食品与非食品价格的长期均衡关系与短期非线性调整——基于两区制门槛协整模型的实证研究 总被引:1,自引:0,他引:1
食品通胀率与非食品通胀率之间的测量缺口近期持续扩大,引起了市场广泛关注。文章根据1994年1月至2010年8月的食品价格与非食品价格数据,运用两区制门槛误差修正模型研究两者的长期均衡关系和短期价格调整以及传导机制中的非线性特征。结果发现,食品通胀率与非食品通胀率存在门槛协整关系,而且估计缺口稳定,这表明测量缺口夸大了两者的真实偏离。文章还发现了食品价格传导的新信息内涵,即食品价格对非食品价格具有非线性的价格传导性:短期内偏离主要是食品价格上升造成,尤其是在高通货膨胀区制,偏离速度有加快趋势。两区制的Granger因果关系检验发现,在极端区制,食品价格通胀与非食品价格通胀具有双向的短期Granger原因,即两者相互领先;而在正常区制,食品价格通胀与非食品价格通胀具有双向的长期Granger原因。 相似文献

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。 相似文献

Abstract. Core inflation plays an important role in the deliberations of monetary policy-makers. In this paper we evaluate a number of measures of core inflation constructed using euro-area data. In addition to the traditional exclusion-type core measures, we examine two newer ones, documenting their properties and evaluating their performance in terms of their ability to track underlying or trend inflation in real time. We focus on core measures derived from the Harmonized Index of Consumer Prices (HICP) as the European Central Bank has chosen to define its mandate for price stability in terms of this index, and because this is the only index of consumer prices that is compiled in a comparable manner across all members of the European Union. We document significant excess kurtosis in the cross-section distribution of price changes in the euro area, and show that several categories of prices are more volatile than those typically excluded from traditional measures of core inflation. Contrary to what one might expect, traditional measures of core inflation are not significantly less volatile than headline measures. We document the superior performance of alternative measures of core inflation in tracking trend inflation on average, but show that none of the various measures of core gave significant advance warning of the pickup in trend inflation at the beginning of 1999. 相似文献

The paper explores the extent to which products follow systematic pricing patterns over their life cycle and the impact this has on the measurement of inflation. Using a large U.S. scanner data set on supermarket products and applying flexible regression methods, we find that on average prices decline as items age. This life cycle price change is often attributed to quality difference in the construction of CPI as items are replaced due to disappearance or during sample rotations. This introduces a systematic bias in the measurement of inflation. For our data we find that the life cycle bias leads to the underestimation of inflation by around 0.30 percentage points each year for the products examined. 相似文献

Inflation targeting is currently the policy of choice for central banks. This policy invariably targets consumer price inflation, which is only one of many available price level indices (such as prices of new investments and house prices). As there is no stable relationship between these price levels, and as differences in developments between the different price levels might induce destabilizing behavior, there is no reason why “low and stable” consumer price inflation should guarantee monetary and financial stability. Following John Maynard Keynes, a “low and stable” increase of average nominal wages might do a better job. As price levels are designed to estimate the purchasing power of spending power and as income, and spending power are used to not just consume or invest but also to pay down many kinds of (gross) debt, it is advisable to use a joint definition of monetary and financial stability, which combines stable purchasing power of monetary income with a stable ability of households and companies to pay off debts. 相似文献

Strategic Choice of the Price Structure and Entry Deterrence Under Price Cap Regulation 总被引:2,自引:0,他引:2
This paper shows that a price‐capped firm under the threat of entry in some of the markets it serves can strategically manipulate its price structure to deter entry. In doing so, the regulated firm uses the price cap constraint as a commitment device to an aggressive pricing behaviour in case of entry. A (dynamic) price cap generally entails that the prices allowed today are a function of the previous‐period prices and that the tighter is the constraint on each price, the larger is the quantity sold of this good in the previous period. Hence, the regulated firm may strategically choose its price structure before entry to place a tighter regulatory control on the prices set in the (potentially) competitive markets and to make it optimal to charge in these markets – in case of entry – prices so low that entry is unprofitable. 相似文献

国际石油价格与通货膨胀的溢出效应及动态相关性 总被引:5,自引:0,他引:5
国际石油价格大幅波动不可避免地给全球经济带来了一定程度的冲击和影响。文章采用向量自回归、多元GARCH-BEKK和DCC-GARCH模型对中美两国通货膨胀与国际石油价格之间的均值溢出效应、波动溢出效应及动态相关关系进行了实证检验。检验结果表明,国际石油价格与中国通货膨胀不存在任何方向的均值和波动溢出效应,美国通货膨胀与国际油价则存在双向显著的均值和波动溢出效应;中国通货膨胀与国际油价的动态相关关系显著弱于美国,不易受到国际油价的冲击和影响。从整体上看,当前中国通货膨胀与国际石油价格的关联性并不显著,但随着我国石油消费对进口依赖程度的不断提高,石油安全问题在可预见的未来将成为中国需要应对的一个现实挑战。因此,相关部门应及早采取有效措施,应对未来石油冲击对宏观经济的影响。 相似文献

We propose a general equilibrium model that explains the empirical evidence of the hump-shaped response of inflation to a monetary policy shock. The model replaces backward-looking indexation à la Christiano et al. [2005. Nominal rigidities and the dynamic effect of a shock to monetary policy. Journal of Political Economy 113(1), 1-45] with a dynamic externality into the production function of firms. The model, armed with sticky wages and variable capital utilization, has two offsetting effects on real marginal cost over the business cycle. First, increasing factor prices raise real marginal cost in response to an expansionary monetary policy shock in the intermediate run. Second, a dynamic externality reduces real marginal cost in the short run because it raises productivity in response to an increase in output following the shock. Overall, the resulting short-run decrease and intermediate-run increase in marginal cost replicate the hump-shaped behavior of inflation under purely forward-looking price and wage Phillips curves. 相似文献

Models of the cost of inflation often conclude that inflation misallocates resources. For example, inflation may lead to an increase in the variability of relative prices and it is often claimed that this increase in variability leads to a misallocation of resources. This claim raises the following empirical question, does inflation alter the composition of real output; that is, does it change real output shares? We examine this question using dynamic panel data methods for nine sector panels each with seven OECD countries from 1970 to 2005. We find evidence that inflation changes the real shares of some sectors even when inflation is treated as endogenous. 相似文献

We estimate a small DSGE model by full information Bayesian techniques on the basis of Israeli data from 1995 to 2006. The model was first developed and estimated by means of classical GMM in Argov and Elkayam (2010), and since then it has been used at the Bank of Israel for monetary policy analysis. It is widely believed that in 2007 (out of sample year) as elsewhere worldwide, inflation rose in Israel due to high commodity prices in global markets. However, our baseline model attributes most of the high inflation in 2007 to supply shocks. One conjecture is that this model's result derives from the inappropriate original use of the unit value of imported consumer goods (which do not include unprocessed food and energy) as the main foreign price measure. We test this conjecture by re-estimating the model with various other foreign price measures that typically do reflect the global rise in commodity prices and compare the log-marginal likelihoods. We find that no other price measure outperforms the original choice in the sample period. Only the foreign trade-weighted CPI equals the performance of the original choice while improving the 2007 interpretation of inflation, and should therefore be considered the main foreign price measure. The proposed methodology for comparing the suitability of alternative measures for observable variables can be applied to any model with exogenous variables that are characterized by univariate equations. 相似文献

A commodity‐price boom is under way. What does this boom mean for inflation in countries with substantial net commodity exports? The answer depends on movements in commodity prices, changes in foreign exchange rates and the determinants of domestic price inflation. We estimate equations to provide indications of the strength of each of these forces for both Australia and Canada. The results show that world commodity prices move pro‐cyclically with world industrial production and that rates of change in commodity prices are directly related to domestic inflation in both countries. However, there is an offsetting impact of exchange‐rate changes, which is strong enough in the case of Australia, but not Canada, to substantially eliminate the inflationary impact of a commodity‐price boom. 相似文献
