Models of cinema demand have tended to employ aggregate data and focus on price and income as key variables. Surprisingly, the effects of travel time and location have not been formally investigated. The authors do so, following developments in the environmental economics literature, by presenting estimates of individual travel cost models for multiplex and nonmultiplex cinemas. A key finding i...

Existing user performance models of navigation for very large documents describe trends in movement time over the entire navigation task. However, these navigation tasks are in fact a combination of many sub-tasks, the details of which are lost when aggregated. Thus, existing models do not provide insight into the navigation choices implicit in a navigation task, nor into how strategy ultimatel...

The procyclical behavior of prices has been a staple of business cycle lore since the work of the early NBER business cycle researchers. This paper reexamines that empirical fact. The aggregate data do not support procyclical price movements as a stable feature of the business cycle. The only episode where it is a robust feature of the data is the period between the two world wars, particularly...

Rarely does a new technology emerge that galvanizes a dramatic rethinking of the nature of commerce. The Internet is such a technology. At this early stage, it is difficult to appreciate fully the importance of the Internet, but some speculate it might be as momentous as the arrival of the telegraph (Cohen, Delurg, and Sysmar 2000; Standage 1999). Radically new communication technologies such a...

In many cases, aggregate data is used to make inferences about individual level behavior. If there are social interactions in which one person’s actions influence his neighbor’s incentives or information, then these inferences are inappropriate. The presence of positive social interactions, or strategic complementarities, implies the existence of a social multiplier where aggregate relationship...

The common goal of new protocols, such as 4G, WiMax, and Mesh, is to achieve higher aggregate data rate. This goal can be achieved only by minimizing the inefficiencies in the network. A large part of the inefficiencies is related to unknown parameters such as wireless channel, link quality, and queue state. Although these unknown parameters are implicitly or explicitly available at sources and...

In-network data aggregation is widely recognized as an acceptable means to reduce the amount of transmitted data without adversely affecting the quality of the results. To date, most aggregation protocols assume that data from localized regions is correlated, thus they tend to identify aggregation points within these regions. Our work, instead, targets systems where the data sources are largely...

Computing a -attribute datacube requires the computation of an aggregate function over all groups generated by interrelated GROUP-BYs. In this paper, we focus on multi-cube computation. We extend the algorithms for single datacube computation to process multiple datacubes simultaneously. The issue we intend to explore is the memory utilization. We propose two multi-cube algorithms, namely, a so...

In this paper, we investigate the implications of non-separable preferences over durable and nondurable consumption for asset pricing tests when adjusting durable consumption is costly. In an economy without adjustment costs, in which a frictionless rental market exists for the durable good, the standard Euler equation with respect to nondurable consumption will hold for each individual agent a...

With the trend toward greater urbanization and the rapid emergence of mega-cities continuing unabated, many policy makers ask themselves whether some cities are becoming too large, and whether policies should be aimed at stimulating the growth of intermediate-sized cities. In this chapter we use a simple model of a system of cities, together with some basic urban and aggregate data, to answer s...
