Methodology and application of price analysis

Summary This paper deals with the relationship between the development of unit costs and prices of production factors and the development of the prices of final products. The investigation of these relationships during the various stages of production in the economic process, an activity called price analysis, may contribute to the analysis of inflation. In this respect the influence of the wage rate on the development of the prices of final expenditure is more considerable than the influence of the prices of imports of goods and services. However, taking into account the modifications in the structure of production, particularly regarding labour productivity and import substitution, the main explanation of the price increase in 1976 compared with 1970 of three categories of final expenditure,viz. exports of goods and services, private consumption expenditure and gross fixed capital formation of enterprises is to be found in the unit costs of imports of goods and services rather than in the unit labour costs.

Incumbent’s price response to new entry: The case of Japanese supermarkets

Large-scale supermarkets have rapidly expanded in Japan over the past two decades, partly because of zoning deregulations for large-scale merchants. This study examines the effect of supermarket openings on the price of national-brand products sold at local incumbents, using scanner price data with a panel structure. Detailed geographic information on store location enables us to define treatment and control groups to control for unobserved heterogeneity and temporary demand shock. The analysis reveals that stores in the treatment group lowered their prices of curry paste, bottled tea, instant noodles, and toothpaste by 0.4–3.1% more than stores in a control group in response to a large-scale supermarket opening.     

Regional Mc parity: do common pricing points reduce deviations from the law of one price?

This paper analyses price differences of McDonald’s products in four different countries. I show that pricing at pricing points in different currencies may contribute to explaining deviations from the law of one price. Observing strictly equal prices is more probable if prices are set at psychological and fractional pricing points in a common currency. The latter is also found to reduce the size of price deviations. Additionally, price differences increase as transaction costs increase. Based on this data set there is no evidence that the euro has reduced price deviations.     

Price variability and price convergence: Evidence from Indonesia

This paper evaluates price variability and price convergence in Indonesia. Using price indices of 35 products in 45 cities from January 2002 to April 2008, this study shows that, during the observed period, prices in Indonesia converged to the ‘relative’ law of one price. The price variability of one product across cities is found to be smaller than the price variability of all products within a city. Transportation costs and the level of development matter to price variability. This study also reveals that the average speed of convergence, which is measured by the half-life, for perishable goods is about 9 months, non-perishable goods 32–36 months, and services 18–19 months, while the median of the half-life of all products is about 16–17 months. The speed of convergence depends on the initial price difference, but not the distance between cities.

Inflation and relative price variability: Evidence for India

This study decomposes relative price variability into a component due to inflation and a component due to real factors. The empirical results for India suggest that real factors account for 55% and inflation accounts for 45% of the variability in relative price changes. The proportion of inflation induced relative price variability increases with the rise in inflation, implying that inflation has distortionary effects on the structure of relative prices. Further, larger part of variability in the relative price changes seems to have been generated by fluctuations in the relative prices of a few commodities. The sector wise analysis shows that the major share of total relative price variability is contributed by fluctuations in the prices of manufactured products. The more crucial inference that emerges from the empirical analysis is that the inflation rate at which variability of relative price changes is minimum is found to be 4.5%, which is consistent with the official threshold rate often claimed by the Reserve Bank of India.     

International Price Linkage within a Region: The Case of East Asia

This paper investigates how “prices” in East Asian economies correlate with those in Japan and the United States. The analysis is particularly noteworthy because although the East Asian economies are geographically close to Japan, their currencies have been tied more closely to the U.S. dollar. In this paper, we analyze two different types of “prices”: overall price levels in terms of the same currency and relative prices among different commodities. We demonstrate that overall price levels in the East Asian economies are more closely related to those in the United States. However, the relative prices in East Asia, especially those in Taiwan and Korea, are more closely correlated with those in Japan. These price correlation patterns are in marked contrast with those in other regions.J. Japan. Int. Econ.December 1993,11(4), pp. 643–666.

Trends,cycles and asymmetries in the terms of trade of primary commodities from developed and less developed countries

The paper examines the Prebisch hypothesis that primary product prices relative to the price of manufacturers fall during cyclical downturns by more than they rise during cyclical upturns and that this is an independent explanation of the secular tendency of the net barter terms of trade to move against primary commodities. An important distinction is made between primary products exported by less developed countries and those exported by developed countries. The greater cyclicality of primary product prices, and the long-run deterioration in their terms of trade since 1954 are confirmed, but there is little support for the Prebisch thesis that primary product prices relative to manufacturers are move sensitive on the downswing than the upswing.     

Stock price targeting and fiscal deficit in Japan: Why did the fiscal deficit increase during Japan’s lost decades?

The purpose of this paper is to explain why Japan’s fiscal deficit increased so dramatically in the 1990s and the 2000s. We focus on the role of “stock price targeting” to explain why the fiscal expenditure increased so much. After presenting a simple model to describe government behavior with an optimistic view about stock price and output growth, the paper tests whether the model can explain Japan’s fiscal expenditure. The empirical results, using biannual and high-frequency data of the 1990s and the 2000s, show that the stock price targeting can track Japan’s fiscal expenditure reasonably well, especially in the 1990s. They imply that without the stock price targeting, the total amount of biannual fiscal stimulus from 1992 to 2000 would have been lower by 2.5 trillion yen on average.     

House price,fertility rates and reproductive intentions

This paper uses national representative data collected through population census and household surveys to estimate the effect of house price on women's childbearing behaviors and intentions. It shows that higher house price significantly lowers women's reproductive probability and that women aged 30 and under, who have been married for 3–5 years, and those with no children are more sensitive to such effect. A significantly negative fertility response to house price is observed among renter families and those with self-built houses, but the response is insignificant for home-owning families. Subsample analysis by child gender reveals that house price mainly affects the probability of male births. Furthermore, women in regions with higher house prices are more willing to have daughters whereas those owning more houses tend to have sons.     

The pitfalls of estimating transactions costs from price data: Evidence from trans-Atlantic gold-point arbitrage, 1886-1905

This paper argues that bilateral spatial price models do not estimate bilateral transactions costs when trade with third cities is important. The paper examines trans-Atlantic gold arbitrage during the gold standard era by assembling a database indicating when trans-Atlantic gold shipments occurred. It shows that two-way gold shipments between New York and London frequently occurred prior to 1901. However, in 1901 gold shipments to London ceased and were replaced by triangular arbitrage shipments through Paris. Consequently, New York and London gold price data cannot be used to estimate New York-London transactions costs after 1901, as no trade took place.

Revising price history: consumer price index for Norway 1492–2018

ABSTRACT

The paper presents a new combined annual cost of living and consumer price index for Norway covering 1492–2018, indicating that Norwegian price history has to be revised. The new historical price index is constructed on a significantly richer data material, which also makes it cover a longer period of price history than the existing one. This is made possible by the compilation of quantitative data from numerous sources, mostly originating from the eighteenth, nineteenth and early twentieth centuries, with grain prices stretching back to 1492. The new combined cost of living and consumer price index is constructed by a Laspeyres approach with shifting baskets for commodities and expenditure groups.

The index makes it possible to follow annual inflation and deflation in Norway for a period of 526 years. When comparing to existing indices, the new series reveals that revisions are needed in Norwegian price history. These make the historical price development more in line with those of the neighbouring countries and more in line with the pattern of wholesale prices.     

A Hedonic price index for the Dutch car market

Summary A hedonic, or constant-quality, price index is constructed for the Dutch car market over the period 1950–72. Quality changes are evaluated by relating car prices to various characteristics in two cross-section analyses, and both the choice of variables - horsepower and weight - and the form of the relation confirm Griliches' analysis of American data. A price index is then constructed by linking a series of year-to-year indices, and it is found that relative car prices have been reduced by about half over the twenty-two year period. Both in the cross-section study and in the price index the analysis is confined to a limited number of car models with major shares of the market.We gratefully acknowledge the help ofR.A.I. andMinisterie van Financieën in providing the data, and ofF. den Butter, J.

International price discrimination: The pharmaceutical industry

It is generally asserted that price discrimination is a common feature of the international pharmaceutical market, resulting in unnecessarily high medical costs to developing countries, since it is pharmaceuticals that are the largest component of their health care expenditures. However, little comprehensive empirical research has been carried out to test this hypothesis. This article compares the prices of identical packages of pharmaceutical products for 32 countries for the year 1975 and examines which factors contribute to thehuge price differences. A strong positive relationship between price level and per capita GDP is found, a 10% increase in per capita income being associated with on average 8% higher drug prices. The implementation of direct price control measures by the government results on average in a 20% price reduction, while government policies such as bulk purchasing through a centralized government agency, promotion of the use of generics and, to a lesser, extent excluding patent protection seem to be sucessful in lowering the general price level of pharmaceuticals. These results suggest that the pharmaceutical industry charges what the market “will bear”.     

How connected are Chinese farmers to retail markets? New evidence of price transmission

This paper examines the extent to which Chinese farmers are connected to regional agricultural markets by looking at the intensity of price transmission from retail markets to the farmgate. This intensity is indicative of the extent to which farmers might benefit from improved marketing opportunities and be exposed to price risks. We estimate the elasticity of farmgate prices to retail prices using price data for 170 markets, in 29 out of 33 provinces of China, at the detail of 12 main products and for the five-year period 1996 to 2000. In each province we find strong linkages between retail and farmgate prices with elasticities ranging between 0.6 and 1 and intensifying over time. This suggests that Chinese farmers are generally well connected to retail markets and that this connectivity has strengthened in the period considered, creating not only new opportunities but also new risks. It is also found that linkages are relatively weak in inland provinces, which is a point of concern in view of Chinese policies to create equal opportunities and equitable growth.     

The effect of oil price on China's exports

The increase in oil prices in recent years has occurred concurrently with a rapid expansion of Chinese exports in the world markets, despite China being an oil importing country. In this paper we develop a theoretical model that explains the positive correlation between Chinese exports and the oil price. The model shows that Chinese growth can lead to an increase in oil prices that has a stronger impact on its export competitors. This is due to the large labor force surplus of China. We then examine this hypothesis by estimating a reduced form equation for Chinese exports using Rodrik [Rodrik, Dani, 2006. What's so special about China's exports? China and World Economy 14, 1–19.]'s measure of export competitiveness, together with the oil price, productivity, real exchange rate, and foreign industrial production over the monthly 1992–2005 period. The results suggest a stable relationship and yields slightly positive values for the price of oil and elastic coefficients for export competitiveness, along with the expected negative elasticity for the real exchange rate.     

The impact of the rise and collapse of Japan's housing price bubble on households’ lifetime utility

This study estimates the impact of the dramatic changes in housing prices during Japan's bubble from the late 1980s to the 1990s on households’ asset accumulation and utility over their life cycle. We construct a life-cycle model explaining households’ consumption/saving and housing decisions under collateral and borrowing constraints. We estimate this model using data from the Family Income and Expenditure Survey (FIES), which includes data on households’ housing wealth estimated from objective information. Using the estimated model, we then conduct a counterfactual simulation in which we assume that housing prices remained constant during the bubble period. Doing so allows us to quantify the gains/losses of lifetime utility due to the housing price boom and bust. We find that 72.2% of the households experienced an average decrease in lifetime utility equivalent to 5.7% of lifetime income. On average, Japan's housing price boom and bust caused a loss in lifetime utility equivalent to 4.7% of lifetime income. Moreover, we compare the impact of the housing price bubble across cohorts and find that the impact was greatest for those who experienced the bubble at ages 35–45.     

Spread of E-commerce,prices and inflation dynamics: Evidence from online price big data in Korea

The so-called Amazon effect is generally defined as such that the increasing competition in the online market and between online and traditional retailers is reducing retail markups and putting downward pressure on prices. This paper investigates the existence of the Amazon effect using online price big data in Korea where e-commerce has been rapidly spreading. For this task, the direct comparison between the online and offline prices were conducted in terms of the levels, trends, inflations, and dynamic correlations for two prices. Online prices for products were collected and classified under the identical classification in the CPI for 14 items in two divisions: food and non-alcoholic beverages and clothing and footwear. Laspeyres formula with identical weights as for the CPIs was applied to compilation of the item- and division-level OPIs (online price indexes) from July 2018 to June 2019. The empirical analyses overall indicated that persistent decreasing trends in the online prices were found when compared to those in the offline prices represented by the CPIs, indicating the existence of the Amazon effect in Korea. More specifically, the OPI covering two divisions decreased by 1.8%, while the CPI increased by 3.6% for the period. In addition, the close dynamic correlations between on-month inflations of two indexes were also found in panel regression and VAR estimations, indicating that a 1% increasing shock to OPI inflation led to an around 0.3% increasing response in the CPI inflation. The dynamic correlations, however, were quite different across the divisions. Those were more pronounced for the division of food and non-alcoholic beverages while they were found little in the division of clothing and footwear.     

The impact of world oil price shocks on macroeconomic variables in Vietnam: the transmission through domestic oil price

This study examines the impact of world oil price shocks on macroeconomic variables in Vietnam with a focus on the transmission channel of domestic oil prices. The Structural Vector Autoregression model with two blocks of real economy variables and monetary variables is employed. The world oil price follows an autoregressive process to reflect the exogenous nature of world oil price shocks to the domestic economy. The retail domestic oil price is determined simultaneously by only the world oil price due to the government's control of the domestic oil market. Using monthly data in the period between 2009 and 2021, the study indicates that a positive shock to world oil prices will increase the domestic oil prices significantly, industrial production (slightly and only statistically significant in the third month after), and inflation (significantly in 8 months). Besides, the domestic oil price is not the only transmission channel of world oil price shocks to the economy. This result implies forecasting, assessing, and controlling the impact of the world oil price shock on the economy should focus on both domestic oil prices and other indirect channels.
