Consumption patterns in Sri Lanka: a decomposition analysis

Knowing consumer reaction to changes in prices and income is important in formulating microeconomic policies, such as public utility prices and commodity taxation. This paper analyses the consumption patterns of consumer goods grouped into eight broad commodities in Sri Lanka during the period 1975–2016, using a system-wide framework. The analysis indicates that Sri Lankan consumers allocate more than half of their income to food and nearly four fifths of their income to food, housing, and transport combined. The estimated income and own-price elasticities reveal that food, housing, medical care, and transport are necessities; clothing, durables and recreation are luxuries; and demand for all commodities is price inelastic except for recreation. To investigate the consumption growth pattern, we decomposed the growth in consumption and change in budget shares of the eight commodities into income, relative price, and change in taste. We also simulated per capita consumption expenditure of the eight commodities under various policy scenarios and found that income growth has played a significant role in Sri Lankan consumption patterns.     

A cross-country analysis of consumption patterns

This paper uses the system-wide approach to analyse the consumption patterns in 18 OECD countries. The results show that, on average, the OECD per capita consumption increased by 3% per annum and prices increased by about 7% per annum; OECD consumers spend about half of their income on food, housing and transport. It is also shown that, in most OECD countries, food, housing and medical care are necessities and clothing, durables, transport and recreation are luxuries, and that the demand for all goods considered are price inelastic. The controversial hypothesis of Stigler and Becker (1977) that tastes are the same across countries is also tested and it is found that the OECD consumption data do not support their claim.     

A cross-country analysis of divisia variances of quantities and budget shares

Divisia variances of quantities consumed and budget shares for 105 pairs of countries are analyzed in terms of real-income, relative-price, and residual effects. One result is that luxuries tend to be more expensive relative to necessities in richer countries. The relatively low price of food in rich countries is an important factor for this result.     

Empirical regularities in South African consumption patterns

This article investigates a number of empirical regularities in the South African consumption patterns. The data support the following empirical regularities: (1) variability in consumption systematically exceeds the variability in prices; (2) law of demand; (3) income flexibility is about ?0.5; (4) Engel's law; and (5) the demand hypotheses, demand homogeneity and Slutsky symmetry are acceptable. In contrast to the findings for a number of other countries, another important empirical regularity that consumer's utility function is additive is rejected for the South African consumers. Based on the implied demand elasticity estimates from the preferred model, it is found that food, housing and medical care are necessities, and clothing, furniture, transport and recreation are luxuries and demand for all the commodities are price inelastic.     

Global capital markets,housing prices,and partisan fiscal policies

In recent years, global imbalances have channeled the excess savings of surplus countries toward the real estate markets of deficit countries. By consequence, the deficit countries that attracted lots of foreign capital experienced large run‐ups in house prices, whereas most surplus countries that exported capital exhibited flat or slow house price growth. We first use new house price data and a novel instrumental variable design to show the causal relationship between housing prices and capital inflows, particularly through debt bonanzas. We then argue that international capital flows affect the fiscal policy preferences of both voters and political parties by way of their impact on housing prices. Where capital inflows are large and housing prices are rising, we expect voters to respond by demanding both lower taxes and less publicly‐provided social insurance because rising house prices allow homeowners to self‐insure against income loss. In contrast, declining house prices produce greater demands for social insurance, particularly among those most exposed to housing market risk. We present evidence from two cross‐national surveys that supports these claims, as well as a “before and after” analysis of the housing crash in Eastern Europe. We also show that the connection between house prices and social policy also manifests itself in government spending outcomes, mediated by partisan control.     

Consumption patterns of food,tobacco and beverages: a cross-country analysis

This study considers the consumption patterns of food, tobacco, soft drinks, and alcohol in 43 developed and developing countries. Such an analysis is important for policy issues associated with tobacco, alcohol, and soft drinks. The results show that consumers in the developing countries spend a much higher proportion of their income on food than consumers in developed countries. The proportion of expenditure allocated to the other three commodities, tobacco, alcohol, and soft drinks, are similar in the two groups of countries. On average, people around the world allocate about one quarter of their income on food, 2.6% on tobacco, 3.2% on alcohol and 1.2% on soft drinks. The income elasticity estimates reveal that food is a necessity in most countries, while tobacco and alcohol are necessities in most of the developed countries and luxuries in a majority of developing countries. Soft drinks are a luxury in a majority of the developing as well as the developed countries. The own-price elasticities show that demand for all four commodities is price inelastic in all countries.     

Profit Differences and Corporate Power: Some Empirical Surprises

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.     

Democracy,Rule of Law,Corruption Incentives,and Growth

We bridge the gap between the standard theory of growth and the mostly static theory of corruption. Some public investment can be diverted from its purpose by corrupt individuals. Voters determine the level of public investment subject to an incentive constraint equalizing the returns from productive and corrupt activities. We concentrate on two exogenous institutional parameters: the “technology of corruption” is the ease with which rent‐seekers can capture a proportion of public spending. The “concentration of political power” is the extent to which rent‐seekers have more political influence than other people. One theoretical prediction is that the effects of the two institutional parameters on income growth and equilibrium corruption are different according to the constraints that are binding at equilibrium. In particular, the effect of judicial quality on growth should be stronger when political power is concentrated. We estimate a system of equations where both corruption and income growth are determined simultaneously and show that income growth is more affected by our proxies for legal and political institutions in countries where political rights and judicial institutions, respectively, are limited.     

How do consumers respond to house price declines?

Movements in house prices and consumer spending are closely correlated in many developed nations. Much debate exists on whether this relationship is causal arising from either wealth effects or via borrowing constraints. This paper uses a unique survey question on consumer responses to house price falls to explain the relationship between house price movements and consumer spending among households in the United Kingdom. 30% of households report they would cut back consumption as a direct response to house price falls. Households who reported they were borrowing constrained were much more likely to report they would cut consumption.     

PRICES AND PRICE ANALYSIS IN THE FRAMEWORK OF THE NATIONAL ACCOUNTS

The paper discusses the role of prices in the framework of the new System of National Accounts (SNA) in terms of three major uses: (1) deflation, (2) price indicators, and (3) price analysis. Following a brief review of the price and quantity measures required by the new SNA with its emphasis on deflation of commodity flows and input-output accounts, in addition to the more conventional deflation of final demand categories, the paper discusses some of the conceptual, methodological and data problems involved in implementing the various uses of prices in the new SNA. Implementing the use of prices as deflators depends, in part, on the concept of output selected (national versus domestic; gross versus net), and which of six concepts of valuation, ranging from purchasers'value to true factor cost, is used. Some of the difficulties in deflating nonmarket flows (e.g., interplant transfers) and industry value added, based on the double deflation method, are discussed. In concept price deflators, which have shifting weights, cannot be used as price indicators, which should have fixed weights. In practice, this is often disregarded and the deflators are used as price indicators. The paper support the SNA recommendation for the development of price indexes with fixed weights to be used as price indicators, in addition to the implicit price deflators. Research in the United States indicates that differences in weights can result in different price measures for various subperiods, components of demand and sector output. Periodic revisions in weights to provide more current fixed weights for price and quantity indexes in each subperiod may minimize the problem but it introduces a new problem—lack of comparability with the constant price tables in the SNA which have fixed weights for the entire period. The new SNA provides a comprehensive and integrated framework for price analysis including the analysis of the structure of aggregate price changes, the industrial origin of final demand prices, and the impact of price change in one sector of the economy on the rest of the economy. Some major gaps which need to be overcome in order to implement the use of the new SNA for price analysis include the development of industry capital stock estimates, separate estimates of proprietors’income, reconciliation of value added and distribution share estimates, and the development of a wide variety of information to supplement the conventional input-output tables in the SNA. Implementing the various objectives of price measures within the framework of the accounts will require a number of improvements in existing price measures and expanding the scope of coverage. “List” prices should be superseded by “transactions” prices and better techniques and data need to be developed to provide for quality adjustment of prices. Coverage will need to be expanded to include services, freight rates, trade margins, government expenditures, and also fill in gaps for many manufactured products. Finally, where possible, use of unit values as price indexes or deflators, e.g., imports and exports, should be replaced by direct price measures.     

Effects of Multilateral Trade Liberalization on Prices*

To analyze the effects of simultaneous tariff reductions by multiple importing countries on prices, we construct a simple three‐country model where a good is produced by a monopolist with nonconstant marginal cost and imported by two countries. We compare two representative tariff‐reduction formulas: the “fixed‐amount” and the “uniform percentage” reductions. The uniform percentage reductions may increase the consumer price in the importing country, whose initial tariff is lower. Thus, importing countries with relatively low tariffs may prefer a bilateral trade agreement to a multilateral one to ensure consumer gains.     

Why Has Japan Failed to Escape from Deflation?

Japan has failed to escape from deflation despite an extraordinary monetary policy easing over the past 4 years. Monetary easing undoubtedly stimulated aggregate demand, leading to an improvement in the output gap. However, since the Phillips curve was almost flat, prices have hardly reacted at all. Against this background, the key question is why prices were so sticky. To examine this, we use sectoral price data for Japan and seven other countries including the USA, and use these data to compare the shape of the price change distribution across the eight countries. Our main finding is that Japan differs significantly from the other countries in that the mode of the distribution is very close to zero for Japan, while it is near 2% for other countries. This suggests that while in the USA and other countries the “default” is for firms to raise prices by about 2% each year, in Japan the default is that, as a result of prolonged deflation, firms keep their prices unchanged.     

Understanding International Price and Consumption Disparities

This study proposes a new measure of the tradability of 120+ commodities based on price dispersion. This approach is used to construct price indices of tradables and non-tradables for 150+ countries. The expenditure share of tradables is lower for richer countries, while the relative price of non-tradables, which plays an important role in the determination of real exchange rates, is higher. Secondly, a common-factor approach (based on principal components) is introduced to compress the large volume of information on prices and quantities consumed globally. We find that cross-commodity correlations are higher for prices than for consumption. In addition, income is responsible for most of the variation in the first principal component of consumption but explains less of the first price component. This suggests consumption are driven primarily by domestic factors, while prices are determined by factors outside the country, along the lines of the Purchasing Power Parity theory.     

基于广义虚拟经济视角下的中国居民消费与房价关系研究

根据居民消费理论,一般而言财富增加会促进消费,国外大量经验研究已证实了房价对消费存在正向的作用。但对于中国而言,房价上涨(财富增加)似乎并没有带动消费的增加?这是什么原因呢?我们认为房价上涨不仅有财富效应,也有与之相对应的替代效应(或称为挤出效应),这是因为短期内房价上涨使得人们购房支出增加而挤出日常消费。另一方面,基于广义虚拟经济视角的消费者心理分析也能更好地解释这一现象。本文利用1999-2010年我国的省际面板数据进行估计后发现,在我国,房价上涨会对消费的变动产生显著的负影响。对此,本文认为,这主要是由于替代效应造成的,同时中国以家庭为观念的社会结构也使得人们宁愿挤出日常消费也要承受"房奴"的生活。     

SELECTED PROBLEMS OF INTER-COUNTRY COMPARISONS ON THE BASIS OF THE EXPERIENCE OF THE EEC

The formidable expansion in the scope of the United Nations International Comparison Project has brought into evidence limitations of the methodology used in the first three phases. The author considers that there are two indispensable conditions needed to give renewed impetus to the ICP: (a) the objectives must be redefined, and (b) the methodology must be built on an entirely new basis. He considers the broad lines of such an evolution to be the following. (a) The objective of volume comparison must be kept distinct from that of purchasing power comparison, given that both the basic material and the formulae to be used at the aggregate level differ in the two cases. (b) At the basic heading level, it is proposed, for both volume and purchasing power comparisons, to replace the multilateral approach by a “minimum scale” binary and unilateral approach, and to use the EKS method. This will make possible an improvement in the accuracy of the estimates, a reduction in the overall costs, and a drastic reduction in execution time. What is more, it would be possible to regionalize the worldwide comparison, in the sense that the results of the basic heading comparisons already obtained at the regional level for regional purposes can be used as an input in the framework of the worldwide comparison. At the aggregate level, in the framework of volume comparison, it is proposed that a constant price procedure in the spatial sense should continue to be used. It is, however, proposed that the prices of the set of countries (GK) be replaced by a structure of common “equi-distant” prices (G). This would permit the elimination of the significant systematic distortions observed in the comparison between rich and poor countries in the first three phases of ICP. What is more, this gives maximum stability to results obtained for the same countries at different geographical levels. By using a set of common “equi-distant” quantities, the same advantage can be obtained in the purchasing power comparison.     

THE INTERNATIONAL COMPARISONS OF CONSUMPTION LEVEL CARRIED OUT BY THE POLISH CENTRAL STATISTICAL OFFICE

1. The problems presented have arisen in practice when carrying out international comparisons of national income and its elements between the CMEA countries. Some rough conclusions are drawn from the nearly completed comparison of consumption level between Poland and Austria. 2. The basic methodological principles of the comparison were similar to the methods used by the group of economists directed by Milton Gilbert and Irving Kravis in their comparison relating to Western European countries. However, a number of new problems have emerged in the course of our work which required practical and theoretical solutions. Some differences in theoretical approach between the Gilbert-Kravis study and ours are discussed. Gilbert and Kravis based their comparison as far as possible on average prices of commodity groups or quantity data, and price indexes for representative goods were applied only as a practical necessity. On the contrary in our study we based our calculation mainly on representative goods and their price relation as this method, in our opinion, takes into account quality differences, which escape from the picture in the Gilbert-Kravis method. 3. Some special theoretical and practical problems of comparisons between countries having market economies and those with planned economies are presented in terms of the example of the comparison of consumption levels between Austria and Poland. Three groups of questions are pointed out: (1) the problem of the definition and boundaries of the aggregates compared; (2) the problem of differences in pricing in the groups of products and services compared, resulting from the social policy of the government concerned; and (3) the problem of differences arising from general price policies in the countries compared. 4. At the end of the paper it is suggested that it would be useful to work out a “statistical information system”, which would make possible detailed comparisons of the volume of consumption among several countries and groups of countries without the need of conducting direct comparisons between each pair of countries.     

The expected inflation channel of government spending in the postwar U.S.

There exist sticky price models in which the output response to a government spending change can be large if the central bank is nonresponsive to inflation. According to this “expected inflation channel,” government spending drives up expected inflation, which in turn, reduces the real interest rate and leads to an increase in private consumption. This paper examines whether the channel was important in the post-WWII U.S., with particular attention to the 2009 Recovery Act period. First, we show that a model calibrated to have a large output multiplier requires a large response of expected inflation to a government spending shock. Next, we show that this large response is inconsistent with structural vector autoregression evidence from the Federal Reserve׳s passive policy period (1959–1979). Then, we study expected inflation measures during the Recovery Act period in conjunction with a panel of professional forecaster surveys, a cross-country comparison of bond yields and fiscal policy news announcements. We show that the expected inflation response was too small to engender a large output multiplier.     

Perceived inflation and the euro: Evidence from an Austrian survey

This paper employs an Austrian micro-dataset to analyze why inflation perceptions became disconnected from official inflation measures in the course of the euro cash changeover. We find evidence that persons who are more often confronted with prices, who expected price increases and who mentally convert euro prices into old currency prices when making price comparisons have a significantly higher perception of inflation. Furthermore, our results indicate that the latter two factors have a persistent impact. This contributes in explaining why price perceptions have not normalized for several years in some countries. The results suggest that policy measures in countries which are going to introduce the euro should address these issues in order to prevent a similar development as experienced in many euro area countries.     

Input Intensity: A Missing Link between Production,Trade Patterns,and Environmental Standards

Trade and production implications of a change in environmental policy using the 2 × 2 Heckscher–Ohlin framework are identified. For otherwise identical economies a difference of environmental policy standards generates two effects: the “effective‐endowment effect” where the abatement activity uses up some resources of the economy leaving less for the production of the final goods and the “factor‐price effect” where changes in the abatement requirement affects factor prices that in turn affect production. The direction and relative strengths of these two effects determine whether production and trade patterns are consistent with or opposite to the pollution haven expectation.     

Is Embodied Technology the Result of Upstream R&D? Industry-Level Evidence

This paper provides an exploratory analysis of whether data on the research and development (R&D) spending directed at particular technological/product fields can be used to measure industry-level capital-embodied technological change. Evidence from the patent literature suggests that the R&D directed at a product, as the main input into the “innovation” production function, is proportional to the value of the innovations in that product. I confirm this hypothesis by showing that the decline in the relative price of a good is positively correlated with the R&D directed at that product. The hypothesis implies that the technological change, or innovation, embodied in an industry's capital is proportional to the R&D that is done (“upstream”) by the economy as a whole on each of the capital goods that a (“downstream”) industry purchases. Using R&D data from the National Science Foundation, I construct measures of capital-embodied R&D. I find they have a strong effect on conventionally measured total-factor productivity growth, a phenomenon that seems to be due partly to the mismeasurement of quality change in the capital stock and partly to a positive correlation between embodied and disembodied technological change. Finally, I find the cross-industry variation in empirical estimates of embodied technological change accord with the cross-industry variation in embodied R&D.
