A CONTEXTUAL ANALYSIS OF THE JOURNEY-TO-SHOP WITH PRICE UNCERTAINTY*

ABSTRACT In this paper we extend the contextual theory of demand to consider rational consumer behavior when the household must deal with some random fluctuation in the prices it faces. Prices at stores reflect “advertised specials,” which are potential cost reductions random across goods, and random in-store price changes, which can only be observed by visiting the store. Our theory of rational behavior includes: (1) calculation by the household of an ex ante plan for its planning period; (2) modification to take account of advertised specials; and (3) rational search behavior to take advantage of random fluctuations observable only on a given day. This theory utilizes an active cash balance as a buffer against random variations from planned daily expenditures, and reformulations of trip circuits to account for patterns of cost-minimizing search.     

STATE INTERVENTION IN LANDSCAPE PRODUCTION: THE WHEATLAND RIOT AND THE CALIFORNIA COMMISSION OF IMMIGRATION AND HOUSING*

The role of the state in landscape production has been little theorized in geography. In this paper, I examine the role played by state institutions in determining landscape morphology by focusing on the activities of the California Commission of Immigration and Housing as it attempted to mitigate the conditions that led to the violent Wheatland “riot” of 1913. This rebellion by radicalized migratory workers was central to the creation of the abundant agricultural landscape of California in the years before the United States entered World War I. By telling the story of Wheatland and the state responses it induced, I hope to move discussions of landscape geography beyond both traditional concerns with landscape as a reflection of “culture” and contemporary concerns with metaphors of landscape as text.     

Planning in the 1990s: An international agenda

This paper, originally presented to the AESOP‐ACSP joint conference in Oxford in 1991, stresses that both in Europe and in the US, there is a major difference for planning in the switch from boom to recession. During the 1990s a major challenge will be to find new ways of public‐private partnership in financing new urban infrastructure at a time when developer contributions — a major innovation of the 1980s — have dried up. This particularly applies to the European high‐speed train system — one critical element of which will run through the East Thames Corridor, one of Britain's major urban developments in the coming years. In the US, planners are likely to remain more locally focused, less internationally concerned, than in a Europe in which national barriers are rapidly eroding.     

X-ray fluorescence analysis of late Roman and Sassanian silver plate

About 200 analyses have been made on late Roman and Sassanian silver objects using energy-dispersive X-ray fluorescence. This has shown that the main feature of the composition of the silver throughout the period and across the geographical area studied was towards high fineness (average silver percentage about 95%). Compositional differences are found between Roman and Sassanian silversmiths' products for the elements copper and lead. Much of the material analysed came from hoards, and using a statistical technique on the analytical data (Discriminant Analysis) broad compositional differences between hoards were found to emerge. The use of different compositions of silver for different joined parts of a single object are discussed.
