This paper presents an empirical verification of the demand price elasticity for piped water in major cities in Poland – it was the main goal of the research. The information concerning the demand reaction to price changes is substantial for sustainable urban water demand. Any prediction of...

The high volatility of the world cocoa price makes the millions of cocoa farmers in the developing world highly vulnerable to poverty. A large volatility in the value of an agricultural commodity is linked to the inelasticity of its supply or demand. Therefore, we test the hypothesis that the...

We show that an insight from taxation theory allows identification of both the supply and demand elasticities with only one instrument. Ramsey (1928) and subsequent models of taxation assume that a tax levied on the demand side only affects demand through the price after taxation....

Recent legalizations of cannabis at the state level in the United States have given rise to renewed interest in the price elasticity of demand for cannabis and implications for likely state excise and sales tax revenues. We use crowdsourced data on prices, qualities, and consumption of cannabis...

How strong are strategic complementarities in price setting across firms? In this paper, we provide a direct empirical estimate of firms' price responses to changes in prices of their competitors. We develop a general framework and an empirical identification strategy to estimate the...

We apply a quadratic expenditure system to estimate price and expenditure elasticities of residential energy demand (electricity and heating) in Germany. Using official expenditure data from 1993 to 2008, we estimate an expenditure elasticity for electricity of 0.3988 and of 0.4055 for space...

This thesis is composed of three essays on the residential electricity demand and its efficient use. In order to design and implement effective energy policy measures it is important for policy makers and utilities to have information on the response of consumers to an increase in electricity...

Least-squares estimates of the response of gasoline consumption to a change in the gasoline price are biased toward zero, given the endogeneity of gasoline prices. A seemingly natural solution to this problem is to instrument for gasoline prices using gasoline taxes, but this approach tends to...

System security in electricity markets relies crucially on the interaction between demand and supply over time. However, research on electricity markets has been mainly focusing on the supply side arguing that demand is rather inelastic. Assuming perfectly inelastic demand might lead to delusive...

Real exports are commonly specified as depending on an indicator of price competitiveness and on a measure of foreign activity. This study empirically investigates the suitability of alternative competitiveness indicators in explaining real exports for a broad group of advanced economies. To...

To model the observed slow response of aggregate real variables to nominal shocks, most macroeconomic models incorporate real rigidities in addition to nominal rigidities. One popular way of modelling such a real rigidity is to assume a non-constant demand elasticity. By using a homescan data...

Many economists suspect that downward nominal wage rigidities in ongoing labor contracts are an important source of employment fluctuations over the business cycle but there is little direct empirical evidence on this conjecture. This paper compares three occupations in the housing sector with...
