INFLATION AND THE DISTRIBUTION OF PRICE CHANGES ACROSS MARKETS: A CAUSAL ANALYSIS

Recent advances in time series methodology are applied to the investigation of causal relationships between monthly changes in the consumer price index and changes in its dispersion across different consumption categories. This dispersion is associated with the degree to which relative prices are changing. Past inflation rates seem useful in forecasting changes in relative prices, but not vice-versa; there is also a significant contemporaneous correlation between these series. Hence, it is concluded that fluctuations in the inflation rate help cause fluctuations in relative prices, but not vice-versa unless the entire effect occurs within a month. The analysis also serves to illustrate a new way to implement the Granger causality concept.     

Frequency of price increases and perceived inflation. An experimental investigation

The effect of frequency of subjective experience of price increases on perceived inflation, i.e. the subjective experience of general price development, is investigated. The paper presents a two-phased psychological model of perceived inflation: first, information about product price increases is gathered in daily purchase. Second, these are integrated into one perceived inflation judgment. In the integration phase, the complexity of the task should trigger heuristic processing: higher frequency of price increases should enhance their availability and thus perceived inflation. Participants simulated purchases in two scenarios. Frequency of products with increased prices was varied while overall expenditure increases as well as relative price increase of individual products were balanced. Experiment 1 presented a high frequency condition with a majority of increased prices relative to previously learned reference prices and a low frequency condition with a majority of stable prices. Experiment 2 balanced cognitive effort for product price change estimation over conditions by replacing absolutely stable prices with slightly increased prices. As predicted, perceived inflation was higher with high frequencies of increased prices, while price increases of individual products were judged correctly. Experiment 3 ruled out the alternative hypothesis that presentation duration, which in the previous experiments correlated with presentation frequency, might have been the determining factor.     

ON INFLATION AND REAL PRICE VARIABILITY

This paper studies the consequences of costly price adjustments for the variability of real prices accompanying inflation. For constant-elasticity demand and cost of production it is shown that a higher demand, a lower cost of production, or a lower cost of price adjustment leads to less intertemporal variability of real prices. If the marginal cost of production does not increase "too" fast, then the average real price is less than the real price that would prevail in the absence of inflation; additionally, a higher demand, a lower cost of production, or a lower cost of price adjustment leads to a higher level of real prices.     

OUR NEW MONETARY STANDARD: THE MEASUREMENT AND EFFECTS OF PRICE UNCERTAINTY, 1880–1973*

U. S. annual inflation rates over the last century are analyzed in an attempt to compare price unpredictability in the recent period with that during the 1880–1915 gold standard period. The movement from negative price change autocorrelations in the earlier period to strongly positive price change autocorrelations in the recent period, is shown to imply an upward shift in the amount of long-term relative to short-term price uncertainty. Empirical evidence on the relationship between the demand for money and actual price change, on the adjustment of interest rates to price changes and on the change in the composition of new corporate debt issues is presented. Evidence suggests that only over the last decade has the public generally recognized the fundamental change from a commodity to a fiduciary standard that has occurred in the underlying monetary framework.     

TAX EFFECTS, PRICE EXPECTATIONS AND THE NOMINAL RATE OF INTEREST

This paper investigates the relationship between price expectations, income taxes and the nominal rate of interest in Canada. Our primary approach was to utilize the rational expectations hypothesis to create a synthetic price expectations series and to apply this series to four models of the determination of the nominal rate of interest; the Yohe-Karnovsky model, the Carr-Smith model, the Feldstein-Eckstein model and the Jenkins-Lim model. The analysis is inconclusive with respect to the Darby hypothesis that income tax considerations will cause the nominal rate of interest to increase by more than the increase in the expected rate of inflation.     

AGGREGATE PRICE SHOCKS AND FINANCIAL INSTABILITY: A HISTORICAL ANALYSIS

This article presents evidence on the relationship between price and financial stability. We construct an annual index of financial conditions for the United States, 1790–1997, and estimate the effect of aggregate price shocks on the index using a dynamic ordered probit model. We find that price-level shocks contributed to financial instability during 1790–1933 and that inflation rate shocks contributed to financial instability during 1980–97. The size of the aggregate price shock needed to alter financial conditions depends on the institutional environment, but we conclude that a monetary policy focused on price stability would contribute to financial stability.     

FINANCIAL INNOVATION, PRICE SMOOTHING, AND MONETARY POLICY

This paper examines an unregulated transaction services market that is subject to financial innovation in an economy that experiences aggregate supply and demand shocks. The availability of this unregulated market to transactors smooths the price response to these shocks. However, financial innovations act as money supply shocks that increase price disturbances. If there is persistence in the real aggregate supply shocks and in the rate of adoption of financial innovations, then the central bank can forecast some portion of the changes in transaction requirements that accompany these shocks and damp the residual variation in prices by accommodating these anticipated needs.     

REPUTATION,PRICE, AND DEATH: AN EMPIRICAL ANALYSIS OF ART PRICE FORMATION

We analyze how an artist's death influences the market prices of her works of art. Death has two opposing effects on art prices. By irrevocably restricting the artist's oeuvre, prices, ceteris paribus, increase when the artist dies. On the other hand, an untimely death may well frustrate the collectors' hopes of owning artwork that will, as the artist's career progresses, become generally known and appreciated. By frustrating expected future name recognition, death impacts negatively on art prices. In conjunction, these two channels of influence give rise to a hump‐shaped relationship between age at death and death‐induced price changes. Using transactions from fine art auctions, we show that the empirically identified death effects indeed conform to our theoretical predictions. We derive our results from hedonic art price regressions, making use of a dataset which exceeds the sample size of traditional studies in cultural economics by an order of magnitude.

INTERNATIONAL PRICE BEHAVIOR AND THE DEMAND FOR MONEY

Oil prices, commodity prices and American monetary policy, the last operating through a variety of channels, have all figured prominently in explanations of the international inflation process in the late 1960s and early 70s. OUT major purpose in this paper is to test these various hypotheses. We do so in the context of a reduced-form rational-expectations price equation which we estimate for the United States and seven other industrial countries using quarterly data for the period 1955 through 1976.
The principal conclusion that emerges from this exercise is that movements in domestic money in these countries served as the key link in the inflation process. The factors that produced these monetary changes, however, differed among countries. Price shocks of various sorts were clearly of secondary importance.
The other important set of conclusions concerns the demand for money. In place of a traditional stock adjustment model, we used GLS with a second-order correction for autocorrelation. We believe this produced more plausible estimates of the parameters of the long-run demand function and of the adjustment process itself.     

ERRORS IN OUTPUT DEFLATORS REVISITED: UNIT VALUES AND THE PRODUCER PRICE INDEX

Output prices are mismeasured because of inadequate adjustments for changes in product quality. Thus, when quality improves, inflation will be systematically over-stated. In this study, I find that the most commonly used indicator of the rate of inflation, the Producer Price Index, misses about 40 percent of the change in quality. However, I also find that the mismeasurement of output prices is constant over time, implying that errors of measurement are not a significant determinant of either the slowdown or recent acceleration in manufacturing productivity.     

AN EMPIRICAL ANALYSIS OF OIL PRICE SHOCKS IN THE INTERWAR PERIOD

This paper presents results that indicate that oil price shocks were economically important in explaining movements in industrial production, and, to a lesser degree, movements in wholesale prices in the period between World Wars I and II. The framework for analysis is a vector autoregressive model estimated using monthly data over 1924:2–38:6 that employs a financial intermediation variable, a measure of relative oil prices, and other variables typically found in small macroeconomic models. The impact of oil price shocks is evaluated through computation of variance decompositions and an historical decomposition over the 1929:9–38:6 period.     

STOCHASTIC INFLATION AND THE OPTIMAL POLICY OF PRICE ADJUSTMENT

This paper analyzes the optimal policy of price adjustment for a monopolistic firm in the presence of stochastic inflation. It shows that an increase in the expected rate of inflation or in the cost of price adjustment leads to an increase in the initial real price and a decrease in the terminal real price in each period with a fixed nominal price. It also shows that the effects of increased riskiness of inflation are ambiguous.     

Expectations of inflation: The biasing effect of thoughts about specific prices

National surveys follow consumers’ expectations of future inflation, because these may directly affect the economic choices they make, indirectly affect macro-economic outcomes, and are considered in monetary policy. Yet, relatively little is known about how individuals form the inflation expectations they report on consumer surveys. Medians of reported inflation expectations tend to track official estimates of realized inflation, but show large heterogeneity between respondents, due to some expecting seemingly extreme inflation. We present two studies to examine whether individuals who consider specific price changes when forming their inflation expectations report more extreme and disagreeing inflation expectations due to focusing on specific extreme price changes. In Study 1, participants who were instructed to recall any price changes or to recall the largest price changes both thought of items for which price changes were perceived to have been extreme. Moreover, they reported more extreme year-ahead inflation expectations and showed more disagreement than did a third group that had been asked to recall the average change in price changes. Study 2 asked participants to report their year-ahead expectations of inflation, without first prompting them to recall specific price changes. Half of participants nevertheless thought of specific prices when generating their inflation expectations. Those who thought of specific prices reported more extreme and more disagreeing inflation expectations, because they were biased towards various items associated with more extreme perceived price changes. Our findings provide new insights into expectation formation processes and have implications for the design of survey-based measures of inflation.     

Poverty and the business cycle: A regional panel data analysis for Spain using alternative measures of unemployment

Conventional wisdom predicts that changes in the aggregate unemployment rate may significantly affect a country’s income distribution and, consequently, have a relevant impact on the evolution of its poverty rate. However, the relationship between labour macroeconomic indicators and poverty seems to have become weaker recently. Using panel data on unemployment and poverty for Spanish regions, we estimate a system GMM model to model this relationship using alternative measures of the unemployment rate. We also test the hypothesis of asymmetric effects of the business cycle on the share of poor individuals in the population. Our results show that unemployment has a positive impact on severe poverty, while inflation has a negative effect. We also highlight the extent to which results differ when alternative intra-household unemployment distribution-sensitive measures are considered. Regarding the existence of asymmetric business cycle effects on severe poverty, our results show that despite the fact that the Great Recession has had a strong and positive effect on severe poverty, the effects of expansions and recessions on poverty are not significantly different.     

TRACKING CUSTOMER SEARCH TO PRICE DISCRIMINATE

The electronic technologies of the Internet make it possible for sellers to track potential customers and discriminate between the informed and uninformed. In this article, we report an experiment that investigates the market impact of firms tracking customers and offering discriminatory prices based on search history. We find that consumers, on average, face the same prices when sellers have the ability to track customers and price discriminate as when sellers post a single price for all buyers. However, informed buyers receive lower prices when sellers can detect buyer search, whereas uninformed buyers receive lower prices when firms cannot track customers. (JEL D43 , L13 , C92 )     

DURABILITY, MAINTENANCE AND THE PRICE OF USED ASSETS

This paper considers assets whose service flow decays at a rate determined by built-in durability and the level of maintenance. A cost minimization model determines optimal durability and maintenance and shows how these variables respond to changes in interest rates, the price of maintenance, and the cost of new assets. The price of old assets adjusts so that the cost of services from both old and new assets is the same. The model provides a framework for analyzing data on automobile scrapping rates and repair expenditures. Data for postwar United States show that scrapping rates are sensitive to the price of repairs relative to the price of new cars. The amount of repairs per car also responds to the relative repair price .     

INFLATION AND ASYMMETRIC OUTPUT ADJUSTMENTS BY FIRMS

Using ordered probit analyses of a unique micro data set, we find evidence of output asymmetry that is systematically related to inflation and to price asymmetry. As predicted by theory, firms are more likely at higher rates of inflation to raise prices in response to positive cost and demand shocks and less likely to lower prices in response to negative cost and demand shocks. The expected effects of higher inflation on output asymmetry, however, come primarily from cost and demand increases and to a lesser (and statistically insignificant) extent from cost and demand decreases. (JEL E3, D4)     

FORECASTING CRUDE OIL PRICE MOVEMENTS WITH OIL‐SENSITIVE STOCKS

This paper uses monthly data from 1984:M10 to 2012:M8 to show that oil‐sensitive stock price indices, particularly those in the energy sector, have strong power in predicting nominal and real crude oil prices at short horizons (1‐month‐ahead predictions), using both in‐ and out‐of‐sample tests. In particular, the forecasts based on oil‐sensitive stock price indices are able to outperform significantly the no‐change forecasts. For example, using the NYSE Arca (AMEX) oil index as a predictor, the 1‐month‐ahead forecasts for nominal crude oil prices reduce the mean squared prediction error by between 22% (for the West Texas Intermediate oil price) and 28% (for the Dubai oil price). Moreover, we find that the directional forecast based on the AMEX oil index is significantly better than a 50:50 coin toss. The novelty of this analysis is that it proposes a new and valuable predictor that both reflects timely market information and is readily available for forecasting the spot oil price.(JEL G17, Q43, Q47, C53)     

TEACHING TOOLS: INTERTEMPORAL RESOURCE ALLOCATION: DISTRIBUTIVE ISSUES SURROUNDING GASOLINE PRICE HIKES

This paper shows that many people misinterpreted the gasoline price increases that followed Iraq's invasion of Kuwait in August 1990. Consumers expressed outrage when prices increased immediately even though a production shortfall did not materialize for several weeks. But by withholding output in the invasion's aftermath arbitragers (including oil companies) reallocated output intertemporally to make more available when it was needed most. The welfare consequences in general depend upon demand elasticities and their rate of change, but in this instance consumer surplus would probably have been maximized with a full and immediate price adjustment and oil companies profited from their restraint.     

ANTICIPATED INFLATION AND AGGREGATE EMPLOYMENT: THE CASE OF COSTLY PRICE ADJUSTMENT

Even if inflation is perfectly anticipated, a firm that finds nominal price adjustments sufficiently costly will reset its price at multi-period intervals. Consequently, its average output will change in a direction that depends on properties of its profit function. On the basis of this observation, which does not involve money illusion, the paper shows that anticipated inflation can stimulate aggregate employment through a process that entails changes in the factor demands of individual monopolistic firms and in the intersectoral allocation of consumer expenditure. Simulations indicate, however, that the gain in aggregate employment is likely to be modest.
