Inflation is often assumed to affect all people in the same way. In practice, differences in spending patterns across households and differences in price increases across goods and services lead to unequal levels of inflation for different households. In this paper, we measure the degree of...

Designing a system of policies for basic goods subsidy adjustments and welfare effects of subsidy reduction widely accentuate by Iranian policy makers and economists. This article tries to answer to the one of the main questions of this matter such as, "What the equivalent amount of money for...

Inflation is often assumed to affect all people in the same way. In practice, differences in spending patterns across households and differences in price increases across goods and services lead to unequal levels of inflation for different households. In this paper, we measure the degree of...

We propose a novel structural method to empirically identify economies of scale in household consumption. We assume collective households with consumption technologies that define the public and private nature of expenditures through Barten scales. Our method recovers the technology by solely...

We compare the empirical performance of unitary and collective labor supply models, using representative data from the Dutch DNB Household Survey. We conduct a nonparametric analysis that avoids the distortive impact of an erroneously specified functional form for the preferences and/or the...

We present a household consumption model that accounts for caring household members, while allowing for noncooperative behavior in decisions on public goods. The intrahousehold consumption outcome critically depends on the degree of caring between the household members. By varying the degree of...

We develop a revealed preference approach to analyze non-unitary consumption models with intrahousehold allocations deviating from the cooperative (or Pareto efficient) solution. At a theoretical level, we establish revealed preference conditions of household consumption models with varying...

We derive revealed preference tests for models where individuals use consideration sets to simplify their consumption problem. Our basic test provides necessary and sufficient conditions for consistency of observed choices with the existence of consideration set restrictions. The same conditions...
