This paper employs quantile panel regression to the study of fuel price elasticities. Contrasting with standard panel approaches, this method reveals the impact of explanatory variables across all points in the conditional distribution of the response variable while controlling for unobserved heterogeneity. Applying quantile panel regression to German household data demonstrates that fuel price...

In 1996, free choice of health insurers was introduced to the German social health insurance system. One objective was to increase efficiency through competition. A crucial precondition for effective competition among health insurers is that consumers search for lower-priced health insurers. We test this hypothesis by estimating the price elasticities of insurers' market shares. We use unique p...

Unit values, calculated as the ratio of household expenditure on a particular food to the quantity consumed, are often used as proxies for market prices in demand studies based on cross-sectional survey data. Because unit values are likely to give biased estimates of price elasticities, Deaton (1987, 1990) developed procedures for correcting these biases. However, empirical evidence on the bias...

The linear approximate version of the almost ideal demand system (LA-AIDS) model is estimated using data from the Lithuanian household budget survey (HBS) covering the period from July 1992 to December 1994. Price and real expenditure elasticities for 12 food groups were estimated based on the estimated coefficients of the model. Very little or nothing is known about the demand parameters of Li...

The aim of the analysis was to determine whether demand in Germany for specific antimicrobial agents is driven by prices that drop considerably when generic substitutes become available. A time-series approach was therefore carried out to explore price elasticities of demand for two different classes of broad-spectrum antimicrobials (fluoroquinolones and cephalosporins) using data on ambulatory...

The substantial subsidizing of energy prices over the years has led to high energy consumption, inefficiencies, fiscal pressures, and environmental problems in Iran. To address the increasing socio-economic problems associated with the energy subsidies, the government embarked on an aggressive energy price reform through which energy subsidies were removed and cash handouts were given to all ho...

abstract this study is an attempt to investigate the influence of targeting subsidies on price transmission pattern in iran's egg market. the targeting subsidies plan was imposed by 20 december 2010. using of daily price time series data, the study was conducted during december 2009 to october 2011. using ecm model, price transmission models were estimated for the two periods (e.g. before and a...

This paper investigates the effect of price variations on the diet composition in Britain. It describes the dynamics of food demand in relation to food prices over time using data from the British National Food Survey (NFS) covering the period 1975-2000. Demand elasticities with respect to price elasticities are estimated by solving a quadratic almost ideal demand system (QUAIDS) model controll...
