Disentangling supply and demand shifts: the impacts on world salmon price

To understand price changes, one must determine the relative impact of supply and demand shifts on price. Conditional on predetermined supply and demand elasticities, we retrieve yearly shifts in regional supply and demand. The relative impact on price from each supply and demand shift is determined through an equilibrium displacement model (EDM). This procedure is applied on a yearly basis for the world salmon market in the period 2002 to 2011. The results indicate a large variation in demand and supply growth both over time and between regions. While average annual price impacts from supply or demand shifts from most regions are not statistically significant, price impacts from supply or demand shifts for specific periods are detected in all but one region. This indicates that the use of smooth trend indicators is likely to be inappropriate for measuring supply and demand shifts and their impacts on price. The procedure presented in this article can be a useful instrument for determining the relative impacts of supply and demand shifts on price in any market with unstable price behaviour.     

Asymmetries in price and quantity adjustments by the competitive firm

Focusing on the crucial role of inventory carry-overs in the production and sales decision, we describe the profit maximizing behavior of a dynamic competitive firm facing random prices. Each firm's behavior is incorporated into a stochastic equilibrium model of the competitive industry with uncertain demand. The industry model exhibits asymmetric cyclical fluctuations of the “Keynesian” sort: when demand is weak, output contracts while price holds at a fixed floor; when demand is strong, price increases as output is constrained by a ceiling. Even in a pure world of constant returns, without increasing costs, the inability to instantaneously coordinate production and sales along with the existence of inventories is sufficient to yield a “backward L” shaped supply curve for the short run.     

Energy price shocks and milk price adjustments

Much previous research on energy price transmission sheds light on the relationship between oil prices and aggregate commodity prices, such as for agricultural products, or food price indexes. This letter uses data from 12 U.S. cities between 2001 and 2011 to examine how energy prices are transmitted to fluid milk products at the retail level. Results indicate the existence of an asymmetric energy pass-through (a rise is transmitted faster than a fall in prices) and that private label milk products are more insulated from energy price shocks and adjust at similar rate with national manufacturer brands.     

The response of aggregate demand to income,money supply,and price level

The response elasticities of (nominal) aggregate demand to the price level and to other nominal variables (e.g., money supply) are both positive but smaller than one. Aggregate demand is less/as responsive to real income than/as to the price level in the short/long run. Real aggregate demand is less/as responsive to real income than/as nominal aggregate demand is to the price level in the short/long run. Some uses of these results are indicated.     

The relative importance of demand and supply shocks some international evidence

In this paper the contribution of demand and supply shocks of the fluctuation of output and employment is analyzed using quarterly data for four countries (USA, UK, FRG and Switzerland) covering the period 1966 to 1988 in a long run restricted VAR framework for employment, output, the interest rate and inflation. For the USA output and employment fluctuations seem to be dominated by supply shocks in theshort and long run, whereas interest and price level variations are dominated by demand shocks. The result obtained with German and Swiss data are, however, different with two respects: The contribution of demand shocks to output and employment fluctuations are substantial up to a time horizon of eight quarters and price level variations, are at least in the short run, dominated by supply disturbances. Finally, the analysis of the UK data shows the US pattern of results for employment and the price level, but demand shocks are important for output up to four quarters and interest rate movements are dominated by supply shocks.     

Fiscal adjustments and asset price changes

This paper examines the links between asset price movements and fiscal adjustments. Our findings suggest that higher asset prices improve fiscal balances and contribute to sustained consolidation. This refers in particular to real equity and real residential property prices. We find evidence that revenue windfalls due to higher residential, commercial property and equity prices can be sustained, thus, improving revenue and primary balances. There is evidence of a positive association of some asset prices changes with expenditure adjustments. Fiscal adjustments and in particular sharp spending cuts are more likely to be successful if undertaken in periods of dire budgetary and economic conditions.     

Dual price and quantity aggregation

In his seminal 1959 paper (in Econometrica), Gorman developed conditions for price aggregation in the context of income-constrained utility maximization. Price aggregation is defined as the existence of group income allocation functions with price indices and income as arguments. This paper develops and proves propositions about quantity aggregation that are dual to the Gorman results. These dual structures contain interesting asymmetries. The quantity aggregation concepts should be useful in the study of organizational structures characterized by decentralized shadow price (demand price) determination.     

The influence of demand and supply side pressures on the quantity and quality of inventive activity

This article arguments the literature on the demand for professional team sports by estimating a demand function for attendance at home matches in the Malaysian Semi-Pro Football League (MSPFL) between 1989 and 1991. A single-equation demand (attendance) function based on a pooled cross-section and time-series panel data set of 399 games is estimated by ordinary least squares, a fixed effects dummy variable covariance model and an error components model. Our findings confirm the importance of market size and championship prospects for the home team (but not the visiting team), as well as divisional status and ‘star’ players. The first match of the season and derby matches also increased attendance.     

The contribution of food and energy price shocks to relative price variability

Food and energy shocks are shown to be significant sources of variation in relative prices of personal consumption expenditures during 1931–1980. This conclusion follows even after recognizing the impact of other shocks based on exports, government spending, money supply, and numbers of military personnel.     

Price and quantity adjustments in the Austrian labour market

Austria is among the very few countries in the European Union which have managed to maintain comparatively low unemployment rates and high employment rates. This study looks at the price and quantity adjustment mechanisms in the Austrian labour market which may have contributed to this favourable outcome. After reviewing briefly the basic theoretical reasoning an empirical investigation is began into gross flow dynamics in the labour market and the cyclical volatility of employment and unemployment in Austria. In international comparison Austrian unemployment is very stable over the business cycle. This is due mainly to the high sensitivity of the labour force on cyclical conditions and, partly, also on the relatively weak responsiveness of employment to cyclical fluctuations in output, the latter being possibly attributable to the high degree of real wage flexibility in Austria. The study proceeds to show that the long-run elasticity of wages with respect to unemployment is indeed quite high in Austria. However, evidence was also found for outsider effects in the Austrian wage setting process. Relative wage structures, on the other hand, appear to be rather rigid.     

Size and sign asymmetries in house price adjustments

Long-run mean-reversion in real house prices is determined by the relative strength of fundamental factors against the short-run influences. This article suggests that the adjustment towards the long-run trend in house prices could display non-linear behaviour due to some intrinsic characteristics of the housing market. Accordingly, sign and size asymmetries as well as possible structural breaks are taken into account in a unit root testing exercise for twenty-nine countries. Our results suggest that mean-reversion exists for seventy percent of the countries in our sample. Moreover, the out-of-sample forecasting performance of our non-linear models in predicting house prices is better than a simple auto-regressive benchmark for some countries.     

On the effect of income and relative price on demand for health care: EC evidence

This paper demonstrates that the relative price of health care could be used to explain the conflicting results of the empirical studies which attempt to measure the income elasticity of demand. Our empirical results, based on a conventional model and cross-national data set for the EC, show that whereas health care may be labelled as a luxury good, the large income effect can be interpreted as merely offsetting the price effect.     

The inefficiency of price quantity bargaining

In bargaining between a buyer and several sellers on prices and quantities, strategic inefficiencies arise. By reallocating quantities between agreements, the buyer can increase its share of the surplus. With two symmetric sellers producing substitutes, the quantity in the first agreement will be higher than the efficient quantity, and the quantity in the last lower, thus implying that sellers are strategically discriminated. When asymmetries are not too large and sellers produce substitutes, the buyer first agrees with the seller with the lowest marginal cost and only the most efficient order of agreement is an equilibrium outcome. When goods are complements, both equilibrium quantities are lower than the efficient levels.     

The theory of economic price and quantity indicators

Summary. This paper develops the theory of economic price and quantity indicators, being the difference analogue of indexes. The properties of indicators and indexes are compared. Observable bounds for the indicators will be derived, as well as two exactness results for Bennet (1920)-type price and quantity indicators.Received: 3 January 2002, Revised: 2 December 2002, JEL Classification Numbers: C43Previous versions of this paper were presented at the Economic Measurement Group Workshop 2001, School of Economics, University of New South Wales, Sydney, 30 March 2001, and at a seminar at the School of Economics, University of New England, Armidale NSW, 7 September 2001.

Intertemporal price discrimination and consumer demand

Under a particular class of utility functions, intertemporal price discrimination (IPD) is not feasible. That is, customers cannot be made to pay different prices for a durable good at different points in time. Other factors such as falling costs, and differing discount rates between buyers and sellers have been found to make intertemporal pricing schemes feasible, or even profitable. None of these factors, however, were fundamental demand differences which give rise to static price discriminations. In this paper we argue that IPD is indeed feasible and sometimes profitable, if only we allow for a nondurable good in the utility function. A simple additively separable utility is examined first, which is then extended to a nonseparable utility function which allows richer substitution/complementary relations between the durable and the nondurable goods. This may help us to better understand the similarities between static and intertemporal price discriminations.     

Using FRED data to teach price elasticity of demand

In this article, the authors discuss the use of Federal Reserve Economic Data (FRED) statistics to teach the concept of price elasticity of demand in an introduction to economics course. By using real data in its computation, they argue that instructors can create a value-adding context for illustrating and applying a foundational concept in economics. Additionally, this pedagogical strategy contributes to developing an expected proficiency for economics majors related to “interpreting and manipulating data” (Hansen 2009, 2012). The authors provide step-by-step instructions on how to use FRED to compute the price elasticity of demand for motor vehicle fuels and gasoline as well as examples of in-class discussion questions and take-home assignments related to this instructional technique.     

Price expectations,disequilibrium adjustments,and macroeconomic price stability

This paper examines the possibility of extending the basic theorems of the risk-free, two-sector, two-factor, constant returns to scale model of production to cover situations with price uncertainty. It is shown that the Rybczynski and Stolper-Samuelson theorems may fail to hold for certain cases while the factor price equalization theorem cannot carry over to the stochastic world, provided firms in the uncertainty sector exhibit decreasing absolute risk aversion. The implications of uniform (relative) changes in both factor endowments and in both (expected) commodity prices are also explored.     

On the relative importance of demand and supply shocks: a panel VAR study for US states

This article is a panel VAR study of demand and supply shocks in the USA using state-level data where structural shocks are decomposed into state idiosyncratic and common components. Decomposition suggests that in all instances, idiosyncratic state shocks rather than common shocks have larger impact and explain most variation in both the state-level unemployment rate and real gross state product. Further, demand shocks are the primary driving force in unemployment rate fluctuations, while both demand and supply are important in output movements to varying degree of impact and importance depending on the use of quarterly or annual data.
