Consumer demand for variety: intertemporal effects of consumption, product switching and pricing policies

The concept of diminishing marginal utility is a cornerstone of economic theory. The consumption of a good typically creates satiation that diminishes the marginal utility of consuming more. Temporal satiation induces consumers to increase their stimulation level by seeking variety and therefore substitute towards other goods (substitutability across time) or other differentiated versions (products) of the good (substitutability across products). The literature on variety-seeking has developed along two strands, each focusing on only one type of substitutability. I specify a demand model that attempts to link these two strands of the literature. This issue is economically relevant because both types of substitutability are important for retailers and manufacturers in designing intertemporal price discrimination strategies. The consumer demand model specified allows consumption to have an enduring effect and the marginal utility of the different products to vary over consumption occasions. Consumers are assumed to make rational purchase decisions by taking into account, not only current and future satiation levels, but also prices and product choices. I then use the model to evaluate the demand implications of a major pricing policy change from hi-low pricing to an everyday low pricing strategy. I find evidence that consumption has a lasting effect on utility that induces substitutability across time and that the median consumer has a taste for variety in her product decisions. Consumers are found to be forward-looking with respect to the duration since the last purchase, to price expectations and product choices. Pricing policy simulations suggest that retailers may increase revenue by reducing the variance of prices, but that lowering the everyday level of prices may be unprofitable.Variety seeking; Intertemporal effects of consumption; product switching; Pricing; Dynamic demand;

Buying Less, But Shopping More: Changes In Consumption Patterns During A Crisis

Market research data are utilized to examine the use of changes in shopping behavior as a method of mitigating the effects of the 2002 Argentine economic crisis. Although the total quantity and real value of goods purchased fell during the crisis, consumers are found to be spending more days shopping. This increase in shopping frequency occurs through consumers purchasing lower-quality goods from a wider variety of shopping channels. This paper provides the first estimates of the magnitude of such effects during a recession, and suggests that this increase in shopping frequency can be an important coping mechanism for households. Shopping more often is shown to enable households to seek out lower prices and locate substitutes, allowing a given level of expenditure to buy more goods.

Real Estate and the Tax Reform Act of 1986

In contrast to the conventional wisdom, real estate activity in the aggregate is not disfavored by the 1986 Tax Act. Within the broad aggregate, however, widely different impacts are to be expected. Regular rental and commercial activity will be slightly disfavored, while historic and old rehabilitation activity will be greatly disfavored. In contrast, owner- occupied housing, far and away the largest component of real estate, is favored, both directly by an interest rate decline and indirectly owing to the increase in rents. Low-income rental housing may be the most favored of all real estate activities. The rent increase for residential properties will be 10 to 15 percent with our assumption of a percentage point decline in interest rates. For commercial properties, the expected rent increase is 5 to 10 percent. The market value decline, which will be greater the longer and further investors think rents will be below the new equilibrium, is unlikely to exceed 4 percent in fast growth markets, even if substantial excess capacity currently exists. In no-growth markets with substantial excess capacity, market values could decline by as much as 8 percent from already depressed levels. Average housing costs will decrease slightly for households with incomes below about $60,000, but increase by 5 percent for those with incomes above twice this level. With the projected increase in rents, homeownership should rise for all income classes, but especially for those with income under$60,000. The aggregate home ownership rate is projected to increase by three percentage points in the long run in response to the Tax Act. The new passive loss limitations are likely to lower significantly the values of recent loss-motivated partnership deals and of properties in areas where the economics have turned sour (vacancy rates have risen sharply). The limitations should have little impact on new construction and market rents, however. Reduced depreciation write-offs, lower interest rates, and higher rents all act to lower expected passive losses. Moreover, financing can be restructured to include equity-kickers or less debt generally at little loss of value.

Factors Affecting Consumer Choice and Willingness to Pay for Milk Attributes

This study used weekly scanner data to determine within the milk market the factors that affect consumer choice of non-rBST and organic products and the implications for the development of niche markets. This was accomplished by first understanding what product attributes affected demand for milk and then determining how much consumers were willing to pay for these attributes. The former was done within the multinomial logit framework while the latter used the hedonic price model to infer WTP. Results showed the price effect for rBST-free was the largest while the price effect for organic was the smallest and that consumers were willing to pay more for both rBST-free and organic milk compared to conventionally produced milk.Consumer/Household Economics,
