Wages and prices in the UK

This paper investigates the relationship between wages and prices in the UK using a VECM formulation and generalized impulse response functions and persistence profiles. Because of significant feedbacks, it finds that fluctuations in wage growth cannot be used directly to predict fluctuations in inflation.     

Safe harbor input prices and market exclusion

An essential input price that is “too high” relative to the downstream price leads to inefficient foreclosure and one that is “too low” induces the vertically-integrated firm to engage in non-price discrimination. Displacement ratios are used to derive the range of safe harbor (downstream/upstream) margin ratios within which no market exclusion arises in equilibrium. The range of admissible margin ratios is increasing in the degree of product differentiation and reduces to a single ratio in the limit as the products become homogeneous. A key policy finding is that complementary price-ceiling and price-floor constraints can prevent both forms of market exclusion.     

Costs,prices and profitablity in UK manufacturing

The 1984 input–output tables make it possible to estimate directly the cost structure of any industrial sector. The results of this calculation are presented for the non-food manufacturing sector for the period 1970–87. This cost estimate is found to be part of a co-integrating set with output prices, in contrast to the specification implied by a Cobb–Douglas production function. The other elements of the equilibrium vector are an index of capacity utilization, positively related to the mark-up, and the variance of inflation (proxying inflation uncertainty), which is negatively related. Import prices have an indirect effect on the mark-up, via demand.     

Trade prices and supply in the UK economy

Current account imbalances are a major source of instability in the world monetary and trading system. Measures to correct these imbalances have largely involved adjustments to exchange rates. In the international trade literature, when the current account is in deficit, the Marshall-Lerner condition is sufficient for a successful devaluation. However, this partial equilibrium condition — apart from being based on the assumption that supply elasticities are infinite — abstracts from how the domestic economy responds to the change in relative prices. In this paper we develop a model of price and output determination in an open economy with imperpectly competitive markets, and draw a distinction between goods which are exported and those which are supplied to the domestic market. This means that we have to determine jointly both export prices and the domestic price of house sales. We show that as long as there is no money illusion in the labour market a fall in the nominal exchange rate raises domestic and export prices proportionally and leaves trade volumes unaffected. However, shifts in domestic absorption relative to overseas demand — by changing relative prices — cause shifts in the relative supply of exports and domestically sold goods and affect the trade balance. Thus fiscal and monetary measures directed towards reducing domestic absorption are more likely to be successful in correcting current account imbalances than exchange rate depreciation.     

Mapping prices into productivity in multisector growth models

Two issues related to mapping a multi-sector model into a reduced-form value-added model are often neglected: the composition of intermediate goods, and the distinction between the productivity indices for value added and for gross output. We illustrate their significance for growth accounting using the well known model of Greenwood et al. (in Am Econ Rev 87(3):342–362, 1997), who find that about 60% of economic growth can be attributed to investment-specific technical change (ISTC). We investigate the role of intermediate goods in their framework and find that, taking into account the composition of intermediates, ISTC may well account for between 93 and 96% of post-war US growth.     

Oil prices and UK industry-level stock returns

In this article, we study whether the behaviour of oil prices can be used as a reliable predictor for the disaggregated industry-level stock market indices. We find strong evidence for the relevance of changes in oil price as a predictor for the returns of UK industry portfolios, while this relevance is heterogeneous across industries. In an out-of-sample framework, we find that both the contemporaneous and lagged oil price changes do predict UK industry stock market returns. The predictive power is more transient for the latter case, and mostly appearing after allowing for time variation in the relative performance. In addition, we find some evidence of asymmetry in the oil–stock price relationships.     

Manufacturing consumption,relative prices,and productivity

I study the patterns of manufacturing consumption expenditures across a broad set of countries that differ in their level of development using disaggregated expenditure and price data. The relative price of manufacturing tends to decline with income and the real share rises with income, particularly for countries in the top half of the income distribution. I find that the nominal expenditure share of manufacturing displays a hump-shape pattern with respect to the level of income per capita. I document that the income elasticities of the relative price of individual manufacturing categories lie in a wide range. However, since most categories have a negative elasticity, the average elasticity for manufacturing is negative. In addition, most aggregations of individual categories, regardless of the criteria used, yield manufacturing sub-sectors that feature a negative income elasticity of its relative price and the variation across income in nominal expenditure shares tends to mask a larger variation across income in real shares. Using a standard development accounting framework, I report large differences in productivity across countries for manufacturing categories. I also find some differences in productivity across countries for manufacturing sub-sectors, but these differences are smaller than the differences between manufacturing and services and considerably smaller than the differences across individual manufacturing categories.     

Exact nonradial input, output, and productivity measurement

Summary. The use of measures originally suggested by Bennet, Bowley, and Hicks in the context of cost of living, welfare, and consumer surplus measurement to measure inputs, outputs, and productivity is examined. Suitably normalized versions of the Bennet-Bowley measures are shown to be exact and superlative measures of input, output, and productivity indicators.

Foreign direct investment,input prices,and host country welfare

This paper analyzes a multinational firm’s foreign direct investment decision, through either greenfield investment or cross‐border merger and acquisition, into a host country with an input monopoly that adopts either uniform pricing or discriminatory pricing. The optimal foreign entry mode could differ under each pricing policy. Under Cournot competition, firms’ technological gap and the initial local market structure are critical to the choice of foreign entry mode, whereas product substitutability is important under Bertrand competition. In the presence of foreign entry, this paper also examines the welfare effects of input price discrimination for the host country.     

Labor productivity and technology heterogeneity

This paper investigates the role of technology club heterogeneity in economic growth and convergence. To do so, we break up labor productivity change into three factors – efficiency, technological, and capital–labor ratio changes – while distinguishing the impact of technology club heterogeneity respectively. This allows us to observe what is happening within and between clubs; as well as between the world and club technologies. Our labor productivity decomposition is nonparametric in nature and thus overcomes the issue of specifying functional forms for the club technologies. Our results reveal the existence of technology heterogeneity and divergence: the world technology is defined by advanced and rich countries; there exists intra-convergence phenomena (mostly due to capital–labor ratio change), but inter-convergences (owning to capital–labor ratio and technological changes) are not found. Finally, we argue that follower and marginalized countries have adopted imitating strategies, but with respect to different dimensions, namely technological change or capital–labor ratio.     

Aggregate productivity and aggregate technology

Aggregate productivity and aggregate technology are meaningful but distinct concepts. We show that a slightly modified Solow productivity residual measures changes in economic welfare, even when productivity and technology differ because of distortions such as imperfect competition. Our results imply that aggregate data can be used to measure changes in welfare, even when disaggregated data are needed to measure technical change. We then present a general accounting framework that identifies several new non-technological gaps between productivity and technology, gaps reflecting imperfections and frictions in output and factor markets. Empirically, we find that these gaps are important, even though we abstract from variations in factor utilization and estimate only small average sectoral markups. The evidence suggests that the usual focus on one-sector DSGE models misses a rich class of important propagation mechanisms that are present only in multi-sector models.     

House prices,land prices,the housing market and house purchase debt in the UK and other countries

This paper brings together information about house prices, land prices, housing market transactions, house purchase debt and personal savings for a number of countries and compares them with those in the UK to see to what extent conditions in the UK are unique and how far something similar is to be observed in the countries of Europe and North America     

Bubbles in UK house prices: evidence from ESTR models

Recent movements in stock and house prices have led to an examination of the presence of bubbles. Whilst, there is extensive research on stock price data, there is relatively less for house prices. This paper uses a present‐value model for house prices to test for the presence of bubbles. The results support the presence of a non‐fundamental component within UK national and regional house prices. In particular, for the majority of series considered, evidence is presented of linear non‐stationarity within the fundamental present‐value relationship, and of non‐linear stationarity, implying the presence of a non‐fundamental, or bubble, component. Furthermore, evidence is presented that prices adjust quicker when they are below fundamental equilibrium, than when they are above fundamental equilibrium, i.e. there is downward price stickiness. These results support the hypothesis that house price dynamics can be characterised by price‐to‐price momentum. Finally, forecast evidence suggests that real prices are likely to adjust downwards and converge with fundamental value.     

Measurement of export prices and changes in product quality

In this paper, the economic theory of index numbers is applied to the construction of industry-level export price indices and export quality indices. These indices are used to make consistent comparisons of export prices and qualities at the same or different points in time. Evidence of quality change over time was found to be an important phenomenon in explaining the variation of unit value indices over time and across countries for some European Union trade flows. About half of the unit value differences among destination countries can be explained by quality differentials. The quality-corrected price indices are potentially useful in any empirical application in which accurate measures of export prices are needed.The authors wish to thank Bienvenido S.

Optimal use of futures markets when input and output prices are uncertain

The purpose of this paper is to extend the analysis of the use of futures markets by a competitive firm facing an uncertain market price for its output to the case where both input and output prices are uncertain.     

Taxation and the asymmetric adjustment of selected retail energy prices in the UK

This paper investigates the adjustment of the prices of four key petroleum products in the UK following changes in the price of crude oil. We find significant evidence that the pre-tax prices of diesel, kerosene, and gas oil adjust more rapidly in an upward than a downward direction, but that the pre-tax price of unleaded petrol adjusts symmetrically. However, these patterns are obscured at the pump once one accounts for fuel duty and value-added tax, raising the possibility that firms can use the tax system to conceal rent-seeking behaviour.     

Detecting long‐run relationships in regional house prices in the UK

Recent developments in the analysis of cointegration in the presence of asymmetric adjustment are extended and applied to data on regional house prices in the UK. This extension is found to have a dramatic impact upon the results derived. In contrast to recent studies employing standard methods, allowance for the possibility of asymmetric behaviour results in the detection of a large number of long‐run relationships between house prices in different regions. A consistent pattern of asymmetric adjustment is observed, with reversion to equilibrium occurring more rapidly (slowly) when house prices in the South of England decrease (increase) relative to other regions. While the results derived support the existence of a ripple effect underlying the observed movements in regional house prices, the extent of cointegration uncovered casts doubt upon the recently proposed notion of weak segmentation in the UK housing market.     

Outsourcing, productivity, and input composition at the plant level

Abstract .  We evaluate the productivity and input composition effects of outsourcing (or subcontracting) for Turkish textile and apparel manufacturing plants. We analyze differences in performance indicators for plants that subcontract inputs or outputs, and find that plants that outsource internationally perform better than those that outsource domestically. We evaluate labour productivity gaps and find that more productive plants both initiate outsourcing and subsequently increase their productivity. We then estimate a flexible production function, controlling for simultaneity and selection bias, and find that higher productivity from input subcontracting involves greater skilled labour intensity but the reverse is true for output subcontracting.     

Assessing the causal relationship between euro-area money and prices in a time-varying environment

The paper provides new evidence on the causal relationship between money and price for the euro area using quarterly data for the period 1980 to 2006, employing two alternative methods of estimation: the vector error correction (VEC) and time-varying coefficient (TVC) estimation techniques. The latter technique has the advantage over the former technique in that it can deal with possible specification biases and spurious relationships that may have arisen from structural changes. The empirical results from the VEC method reveal a bidirectional causal relationship between money and prices. The results from the TVC technique suggest that money is acting as an exogenous process determining the price level.
