City CPI Convergence in Mexico

This paper tests the purchasing power parity hypothesis within a single developing country currency area: Mexico. This work stems from research in comparing price movements across countries and a growing literature on price dynamics within a single currency area. The author uses city Consumer Price Index data for 34 cities in Mexico over the period 1982–2000. He followed the standard procedure of testing for I(1) processes in relative city prices, or city real exchange rates, using univariate and panel unit root tests. The main results of the paper are: First, Mexican city relative prices are stationary—the data rejects the hypothesis that city real exchange rates contain a random walk, but only using panel unit root techniques. Finally, regional demand and supply homogeneity implies stronger evidence for price parity within regions, while there is considerable evidence of regional price convergence, regional homogeneity does not guarantee faster convergence.     

紧缩性货币政策应对当前通货膨胀的低效性

近期我国出现了居民消费物价指数快速上涨的现象,通货膨胀压力逐步显现,货币当局采取了一系列紧缩性货币政策。然而当前通货膨胀的重要特征是结构性价格调整,其深层次原因是扭曲的要素价格体系的调整和经济增长方式的转变,数据也显示货币供给量的平稳增长和通货膨胀率存在背离的现象。因此,继续采取紧缩性货币政策应对当前通货膨胀是低效的,应当综合采取多种政策手段实现对经济的调控。     

Money Demand and Purchasing Power Parity (PPP), in the Republic of South Africa

We have examined empirically two important economic relationships, the Purchasing Power Parity (PPP) and the money demand relationship, among the consumer prices, money, output, interest rates, and the nominal rand/dollar exchange rate of the Republic of South Africa (RSA) for the sample period from 1993 second quarter to 2003 second quarter within the frameworks of co-integration and Error Correction Model (ECM). It is established that the strong version of the PPP including the proportionality and the symmetry hypothesis, is supported. The changes in the rand/dollar exchange rates are influenced by the long term trends in the consumer prices of the RSA and the USA. There also exists a well defined money demand function for this period. The broad money demand is influenced by the consumer prices, the GDP and the interest rates. The short-term interest rates are found to be the own rate of return for broad money and the long-term bond yield is the opportunity cost of holding money. The monetary policy works through the short term interest rates.

     

A CONSUMER PRICE INDEX FOR SWEDEN, 1290–2008

This paper presents a Consumer Price Index for Sweden 1290–2008. Constructing an index that covers more than seven centuries poses conceptual and empirical problems, and demands some methodological innovations. For example, during numerous occasions the currency unit was changed, and in some periods multiple currencies were used at floating exchange rates relative to each other. This paper also presents two different price indices, one that mainly serves the purposes of estimating real prices and real wages, and another that provides a measure of inflation. While the former follows the main currency unit, the latter also takes into account that debased coins were devalued during recoinage.     

Does money have a role in the inflation process? Evidence from Australia

Inflation, defined as a sustained increase in the price level, is considered a monetary phenomenon, as it can be explained within the framework of money‐demand and money‐supply relationships. In the extant literature, money growth is shown to remain causally related to inflation across countries and over time, irrespective of the exchange rate regime and stability of the money‐demand function. Nevertheless, emerging literature suggests a diminishing role of money in the conduct of monetary policy for price stability, especially under inflation targeting. Monetary policy in Australia under inflation targeting since 1993 is an example of policy that denies a relationship between money growth and inflation. The proposition that money does not matter insofar as inflation is concerned seems odd in both theory and the best‐practice monetary policy for price stability. This paper uses annual data for the period 1970–2017 and quarterly data for the period 1970Q1–2015Q1. It deploys both the Johansen cointegration approach and the autoregressive distributed lag (ARDL) cointegration approach to investigate for Australia whether money, real output, prices and the exchange rate (non‐stationary variables) maintain the long‐run price‐level relationship that the classical monetary theory suggests in the presence of such stationary variables as the domestic and foreign interest rates. As expected, the empirical findings for Australia are consistent with the classical long‐run price‐level relationship between money, real output, prices and the exchange rate. The error‐correction model of inflation confirms the presence of a cointegral relationship among these variables; it also provides strong evidence of a short‐run causal relationship between money supply growth and inflation. On the basis of a priori theoretical predictions and empirical findings, the paper draws the conclusion that the monetary aggregate and its growth rate matter insofar as inflation is concerned, irrespective of the strategy of monetary policy for price stability.     

我国价格总水平决定的一个理论模型

开放经济条件下的价格总水平由产品市场、货币市场和劳动市场三个市场达到均衡状态时共同决定,影响我国价格总水平的主要因素包括货币供给量、名义工资水平、利率、汇率和资本市场发展水平。从长期来看,在其他情况不变的情况下,价格总水平随着名义货币供给量、名义工资水平、汇率以及利率的增加而上涨;推动资本市场发展对于促进价格总水平的稳定具有积极作用。     

The impact of oil prices on income and energy

The major determinant of real income growth in Korea is real oil prices, followed by money supply, exchange rates, energy consumption, and government spending. Over the longer horizon, the effects of exchange rates, oil prices, government spending, and money supply become more pronounced. For energy consumption, the most important factor is oil prices, followed by exchange rates, government spending, money supply, and income. For the association between energy consumption and real income, energy consumption influences real income growth only through energy consumption, while real income affects energy consumption only through the error correction term. The findings of the study thus suggest that the level of economic activity and energy consumption mutually influence each other.     

Excess comovements between the euro/US dollar and pound sterling/US dollar exchange rates

ABSTRACT

The aim of this article is to discuss excess comovements of the euro/US dollar and pound sterling/US dollar exchange rates, i.e. we look for comovements of exchange rates which are stronger than implied by the fundamentals. The results of the empirical analysis provide evidence that excess comovements exist for the two exchange rates. A long-run analysis of correlations can verify that a link exists between the correlation dynamics of exchange rates, relative inflation rates, long-term interest rates, economic sentiments and money supply. We find that common movements of money supply, prices and economic sentiments each play a major role in comovements of the exchange rates. From the investigation of the two exchange rates, we conclude that macroeconomic fundamentals can account for the comovement but that common non-fundamental factors also have major significance for the exchange rates.

The effects of macroeconomic factors on South African agriculture

Significant research efforts have been devoted to understanding the effects of macroeconomic factors on the agriculture sector. Analysing the sources of volatility in the industry is critical for designing appropriate policies to stabilize agricultural markets, reduce poverty and increase economic growth. Agriculture is a competitive sector with prices that are more flexible than those in nonagricultural sectors. This article uses annual data over the 1957–2004 period and a vector error-correction model in investigating the dynamic effects of exchange rates, money supply and other macroeconomic variables on the agricultural sector in South Africa. Overall, real exchange rates, interest rates, inflation and money supply (M3) shocks have significant and persistent impacts on agricultural output, prices received by farmers and farm input prices. M3 and interest rate shocks tend to put agriculture in a cost-price squeeze. Agricultural price movements are a source of macroeconomic instability in the country. Real exchange rate shocks shift relative prices in favour of agriculture in the long-run, thereby, boosting farm incomes and accelerating poverty reduction in the country.     

HONG KONG'S INDETERMINACY PUZZLE: INSTITUTIONALIST AND ECONOMETRIC APPROACHES*

During the free-issue regime (1974–1983), Hong Kong's money supply, price level and exchange rates were wholly governed by market forces. The system did not seem to have any nominal anchor. Theoretically its price level was indeterminate, engendering what is called an indeterminacy puzzle. The paper elaborates on the concept of price level indeterminacy and undertakes the question of empirical determination of the price level indeterminacy during the free-issue regime. The empirical investigation employs two distinct approaches - institutionalist and econometric. The results of the two approaches indicate the necessity of a broader approach to historical analyses. The paper also informs us about the relationship among money supply, price level and exchange rate in a regime of fiat money without a central bank.     

我国货币政策对稳定物价有效性的实证分析

2009年以来,面对持续走高的物价,央行采取了连续上调准备金率的政策,以求减少货币供给量,稳定物价。通过建立CPI、广义货币供给量M2和GDP之间的回归模型,对1994～2010年的数据进行回归分析,得出了我国货币政策对稳定物价有效的结论。认为治理通货膨胀要采取多样化的宏观经济政策,注意货币政策、财政政策的搭配使用。同时要加快人民币汇率体制改革,促进产业结构调整和经济发展方式的转变。     

The optimality of nominal contracts

Summary. This paper presents a model in which agents choose to use money as a medium of exchange, a means of payment, and a unit of account. The paper defines conditions under which nominal contracts, promising future payment of a fixed number of units of fiat money, prove to be the optimal contract form in the presence of either relative or aggregate price risk. When relative prices are random, nominal contracts are optimal if individuals have ex ante similar preferences over future consumption. When the aggregate price level is random, whether from shocks to the money supply or aggregate output, nominal contracts (perhaps coupled with equity contracts) lead to optimal risk-sharing if individuals have the same degree of relative risk aversion. Finally, nominal contracts may be optimal if the repayment of contracts is subject to a binding cash-in-advance constraint. In this case, a contingent contract increases the risk of holding excessive cash balances. Received: March 29, 1996; revised version: February 25, 1997     

Causes of Inflation in Europe, the United States and Japan: Some Lessons for Maintaining Price Stability in the EMU from a Structural VAR Approach

Price stability being among the primary goals of EMU monetary policy,it should be interesting to analyse thefactors that led to the disinflationarydevelopments of the last years. Using a structural VAR approach withlong-run identifying restrictions derived from an open-economy macromodel, various factors of inflation for Austria, Germany, Italy, the UnitedKingdom, the United States and Japan and the extent to which they havecontributed to inflation are analysed. These factors are energy price shocks, supply shocks, wage setting influences, demand and exchange rate disturbances and money supply surprises. The latter three are also used to calculate core inflation. Within a smaller model for aggregate EMU data, supply and demand influences are analysed. While supply and demand factors have generally contributed to the inflation decline, monetary policy, enhanced competition, low energy prices and moderate wage setting are featuring most prominent in the recent disinflation process.

Monetary policy in open economies

The recent literature on monetary policy in open economies has produced a strong presumption in favor of activistic policy and flexible exchange rates. We argue that this result may owe much to the combination of two commonly made assumptions: That nominal goods prices are rigid. And that the monetary authorities have a lot of information about the economy. When the source of nominal rigidity is found in wages and monetary policy is conducted according to less information demanding rules (such as a standard interest rate rule) policies that stabilize the money supply or the nominal exchange rate may perform better.     

Money and prices: U.S. Data 1869–1914 (A study with directed graphs)

This paper reconsiders empirical evidence on relationships among money, income, nominal prices, and wheat prices. Error correction and directed acyclic graphs are used to study both lagged and contemporaneous relations in late 19^th and early 20^th century U.S. data. We summarize evidence supporting the view that money was a causal actor in price movement in this period. In the long run (at a five year horizon), over twenty percent of the movement in price is explained by earlier movements in money supply; whereas, wheat price accounts for less than ten percent of this movement. There is also evidence that money supply was not exogenous, as it was determined, in contemporaneous time, by movements in the general price level and income. About forty percent of the variation in money is explained by current or lagged prices and income. There remains considerable uncertainty with respect to role of wheat prices in this period. Innovations in wheat price explain over twenty five percent of the uncertainty in real income at the five year forecast horizon – suggesting wheat price as either causal or proxying for more fundamental causal forces in the U.S. economy over our period of analysis.

Liquidity and crude oil prices: China's influence over 1996–2011

Movement in China's money supply is shown to drive the movement in world money supply over the last fifteen years. Structural shocks to G3 (U.S., Eurozone and Japan) real M2 and to China's real M2 are both large over 1996:1–2011:12. The cumulative impact of real G3 M2 shocks on real oil prices is small and statistically insignificant. In contrast, the cumulative impact of China's real M2 on the real price of crude oil is large and statistically significant. Following a sharp fall in real oil price in the last half of 2008, the cumulative impact of China's real M2 on the real price of crude oil is particularly substantial in the recovery of oil price during 2009 from a low of $41.68 for January 2009. The analysis sheds light on the causes of movement in oil prices over the last fifteen years and in assessing the relative importance of China in the upsurge of the real price of crude oil.     

The Real Exchange Rate Always Floats

This paper makes two main points. First, irrespective of nominal exchange rate arrangements, the real exchange rate always floats — if not through nominal exchange rate adjustment, then through price change. Further, because prices and wages tend to be sticky, the adjustment of real exchange rates towards long–run equilibrium takes time, as witnessed by long–lasting currency misalignments around the world. In second place, real exchange rates are rather likely to fluctuate on their way towards long–run equilibrium because of the dynamic interaction between real exchange rates and the current account or, put differently, because the structure of lags with which exchange rates impact the volume of exports and imports may give rise to oscillatory behaviour.
