One of the most enduring relationships in economics is that proposed by Ernst Engel in 1857: “The poorer is a family, the greater is the proportion of the total outgo [family expenditures] which must be used for food. … The proportion of the outgo used for food, other things being equal is...

Economic policies are often judged by a handful of statistics, some of which may be biased during periods of change. We estimate the income growth implied by the evolution of food demand and durable good ownership in post-reform Brazil and Mexico, and find that changes in consumption patterns...

In this paper we discuss a number of ways to define and measure the affordability of energy consumption, and we examine the emergence of fuel poverty in Italy in the period from 1998 to 2011. The paper examines the eligibility criteria for claiming the benefits available to support energy...

The present research aims to compare and improve the measurement and, therefore, the definition of what "middle class" represents, for a group of countries in Latin America, namely Colombia,Mexico, Peru, Brazil and Ecuador, using a methodology based on the expenditure of households, compared to...

Modern macroeconomics empirically addresses economy-wide incentives behind economic actions by using insights from the way a single representative household would behave. This analytical approach requires that incentives of the poor and the rich are strictly aligned. In empirical analysis a...

Most simulated micro-founded macro models use solely consumer-demand aggregates in order to estimate deep economy-wide preference parameters, which are useful for policy evaluation. The underlying demand-aggregation properties that this approach requires, should be easy to empirically disprove:...

Previous poverty assessments for Burkina Faso were due to the neglect of some important methodological issues misleading and led to the so-called ?Burkinab? Growth-Poverty-Paradox?, i.e. relatively sustained macro-economic growth, but almost constant poverty. We estimate that poverty...

This paper proposes a methodology for testing for whether tax reforms are pro-poor. This is done by extending stochastic dominance techniques to help identify tax reforms that will necessarily be deemed absolutely or relatively pro-poor by a wide spectrum of poverty analysts. The statistical...

The official estimates of poverty in Pakistan have shown a remarkable and consistent decline in the poverty headcount during the previous decade. This paper examines trends in poverty between 2001 and 2011 using the official food energy intake and the cost of basic needs approaches, both of...

This paper investigates how two effects drive wedges between nominal and real inequality estimates. The effects are caused by (i) differences in the composition of consumption over the income distribution coupled with differential inflation of consumption items; and (ii) quantity discounting...
