The aggregate trade in the market in a community must be accounted for per period of time. As such, the market consists of “flows.” Specifically, the flow of quantity traded is determined after interactions between the two flows of demand schedule and supply schedule; the former slopes...

We explore adoption of mass customization (MC) -- in place of mass production (MP) -- in a profit-driven competitive environment as a solution to the serious problem of overproduction (and all the environmental waste that it generates) endemic in the fashion industry. Building on a demand model...

A monopoly that sells to brand-name loyal customers and to price-sensitive customers must decide whether to carry both name-brand and a private-label products and how much to charge. The monopoly may charge either more or less for the brand name if it carries a private label, and the price...

There are many situations in which a customer’s proclivity to buy the product of any firm depends not only on the classical attributes of the product such as its price and quality, but also on who else is buying the same product. Under quite general circumstances, it turns out that...

We characterize the evolution of markups for consumer products in the United States from 2006 to 2019. We use detailed data on prices and quantities for products in more than 100 distinct product categories to estimate demand systems with flexible consumer preferences. We recover markups under...

This chapter covers recent solutions to aggregation problems in three application areas: consumer demand analysis, consumption growth and wealth, and labor participation and wages. Each area involves treatment of heterogeneity and nonlinearity at the individual level. Three types of...

We show that consumers spend 15% more per day on their credit cards in the ten days following the receipt of a credit card statement than in the days prior to the statement. We test several mechanisms for this effect including mental accounting, optimization of the free float, and liquidity...

Since household consumption depends among others on income, it will be of interest to examine the change of household consumption structure due to income changes. This will be useful to supply chain management as well as policy makers. Our sample refers to Western Europe, USA and Japan during...

It is often claimed that technology improves product quality, which in turn increases consumption although the product price goes up. The question is if this still holds true at national level and especially after the outburst of the economic crisis. Present model hints a major problem that of...

Using scanner data and time diaries, we document how households substitute time for money through shopping and home production. We find evidence that there is substantial heterogeneity in prices paid across households for identical consumption goods in the same metro area at any given point in...
