Increasing the production of organic food is becoming an important environmental target for many governments, and consumer demand for organic food is pivotal in reaching these targets. This paper studies consumer demand for organic and conventional milk, using weekly scanner data from the...

The paper lists salient characteristics of the certainty theory of consumer choice and discusses the import of prominent empirical analyses of the theory. All of them reject the theory's empirical relevance which suggests that the theory is unfit to analyze consumer choice in an uncertain world....

Evidence suggests that household responses to price and income changes are significantly sensitive across income levels and rural-urban location. In this paper, we focus on poor households vs. non-poor households using two definitions of poverty, objective and subjective. We evaluate the...

We characterize three classes of demand systems, all of which are defined nonparametrically: homothetic demand systems with a single aggregator (HSA), those with direct implicit additivity (HDIA), and those with indirect implicit additivity (HIIA). For any number of goods, all the cross-price...

Empirical studies of income distribution and aggregate demand using a structural modeling approach typically find that demand is wage-led in most large, advanced economies. These studies have been criticized for estimating the individual equations for consumption, investment, and net exports...

The paper analyzes food consumption patterns of Vietnamese households, using a complete demand system and socio-demographic information. Demand elasticities are estimated applying a modified Almost Ideal Demand System (AIDS) model on the Vietnamese household survey data in 2006. The results...

Food insecurity and malnutrition are still major challenges for large proportions of households in Sub-Saharan Africa. The empirical literature on food demand, however, suggests mixed evidence on the roles of income and other socio-economic attributes on food demand. This study analyzes the food...

The aim of this paper is to assess the welfare effects of food price changes on urban households' poverty and vulnerability. This is achieved by using Hicksian price Compensating Variation (CV) and compensated price elasticities, based on Quadratic Almost Ideal Demand System (QAIDS). The study...

Changes in energy consumption behaviour of households are recognised as a main contributor to reduced energy demand in developed countries. We investigate the economy-wide impacts of a more efficient electricity consumption behaviour in the presence of demand rigidities and consumption habits....

We study a single product pricing problem with demand censoring in an offline data-driven setting. In this problem, a retailer is given a finite amount of inventory, and faces a random demand that is price sensitive in a linear fashion with unknown price sensitivity and base demand distribution....

Purpose: This study aims to model the demand analysis for solid fuel and its substitute for domestic cooking energy among households in Imo State. Methods: Data on socio-economic characteristics of the respondents, monthly expenditure on energy used for domestic cooking, unit prices, and...

This paper examines demand systems where the demand for a good depends on other prices only through a common price aggregator (a scalar function of all prices). We refer to this property as ``generalized separability'' and provide the functional forms of demand that this property implies when...

Whether couples pool their resources and behave like a unit or spend their income individually is crucial for social and tax policy. In this paper, I provide a test of the income pooling hypothesis using administrative cross-sectional survey data on expenditures and individual incomes of couple...

Whether couples pool their resources and behave like a unit or spend their income individually is crucial for social and tax policy. In this paper, I provide a test of the income pooling hypothesis using administrative cross-sectional survey data on expenditures and individual incomes of couple...

We propose a demand model where consumers simultaneously choose a few different goodsfrom a large menu of available goods, and choose how much to consume of each good. Themodel nests multinomial discrete choice and continuous demand systems as special cases.Goods can be substitutes or...

We estimate direct and indirect energy rebound effects for a wide variety of goods and services in Germany. To this end, we employ a linearized approximation of the popular Almost Ideal Demand System (LAIDS) approach suggested by Deaton and Muellbauer (1980). Excluding measures of energy...

We estimate US household monthly elasticities of demand for some of the more popular organic fruits. To our knowledge, this is the first US-wide, multi-year analysis of price and income elasticities for various organic fruits. We calculate elasticities of demand for low-income, middle class, and...

We develop an asset pricing model with flexible heterogeneity in asset demand across investors, designed to match institutional and household holdings. A portfolio choice model implies characteristics-based demand when returns have a factor structure and expected returns and factor loadings...

The main objective of this article is to analyze the U.S. household final consumption expenditure using a Linear Approximate Almost Ideal Demand System (LA/AIDS) model for the period of 1989 through 2015. The six major groups of goods and services are (1) food and alcoholic beverage, (2)...

Over the last decades, the composition of financial wealth of French households has dramatically changed. We seek explanatory factors for these changes by estimating an extended version of Deaton and Muellbauer (1980) model applied to French households' portfolio choices. We find that most of...

We investigate interfuel substitution in the United States using the minflex Laurent demand system and a century of data (from 1919 to 2012). We relax the assumption of constant parameters in the demand system, and also relax the homoskedasticity assumption, instead assuming that the covariance...

I give conditions under which changes in private spending are accommodated in general equilibrium exactly like changes in aggregate fiscal expenditure. Under such demand equivalence, researchers can use time series evidence on fiscal multipliers to recover the general equilibrium "missing...

This article develops a model of food demand in which the quality and quantity of food purchased and the inter-purchase time are determined simultaneously. We use this model to explore the relationship between a household's cereal purchases and its demographic variables. Households eligible to...
