Quasi‐rational and ex ante price expectations in commodity supply models: an empirical analysis of the US broiler market

A statistically optimal inference about agents' ex ante price expectations within the US broiler market is derived using futures prices of related commodities along with a quasi‐rational forecasting regression equation. The modelling approach, which builds on a Hamilton‐type framework, includes endogenous production and allows expected cash price to be decomposed into anticipated and unanticipated components. We therefore infer the relative importance of various informational sources in expectation formation. Results show that, in addition to the quasi‐rational forecast, the true supply shock, future prices, and ex post commodity price forecast errors have, at times, been influential in broiler producers' price expectations.

Multilateral and Bilateral Loans versus Grants: Issues and Evidence

This paper examines a wide range of issues relating to the mix between loans and grants as well as the degree of concessionality of loans. A number of empirical tests are carried out based on annual panel data over 1970 to 1999 for 22 donor countries and 72 recipient countries. Based on the tests, we observe that for bilateral donors, past grant‐loan mix (and, hence, reflows from past transfers) do not influence the volume of current resource transfers. Our tests also show that the rate of official borrowing by the recipients (and, by deduction, the extent of their past debt burden) is positively influenced by the extent of the concessionality of such loans – irrespective of whether it is in the form of subsidised interest rates or longer grace periods. The paper concludes with a review of the circumstances in which grants, soft loans and non‐concessional loans might have their respective comparative advantage, as well as a discussion of the need, so as to overcome the negative incentive problems of soft loans, for a typical concessional loan package to be separated into two constituent parts. This would enable the recipient to be given the grant component and the option to take from the non‐concessional loan component as much as desired.     

SUPPLY CHAIN INFORMATION SHARING IN A VENDOR MANAGED INVENTORY PARTNERSHIP

Vendor Managed Inventory (VMI) involves the vendor making the replenishment decision for products supplied to a customer based on various inventory and supply chain policies. Information sharing between supply chain members is required in VMI. Sometimes VMI decisions are delayed and/or the information shared is inaccurate. This research examines the effects of information delay and accuracy, and the sharing of sales and forecast information in a VMI environment facing stationary and nonstationary demand. The simulation experiments show the impact of information delay, information inaccuracy, and information sharing on a variety of performance measures, including inventory levels and fill rates.     

Marketplace and personal space: Investigating the differential effects of attachment style across relationship contexts

An individual's tendencies in purely personal relationships seem to lead to related tendencies in consumer relationships. The following article presents a study that illustrates how individual differences in personal relationship attachment style can be used to predict the likely success of consumer relationships. In addition, it illustrates how the success of consumption versus nonconsumption relationships can be explained by the effect of attachment style on the individual's perception of qualities of the relationship. © 2006 Wiley Periodicals, Inc.     

Not all trade restrictions are created equally

There has been great focus in the recent trade theory literature on the introduction of firm heterogeneity into trade models. This introduction has highlighted the importance of the entry/exit decision of firms in response to changes in trade barriers. However, it is typical in many of these models to use iceberg transport costs as a general form of trade barriers that can be interchangeable with ad valorem tariffs. I show that this is not always an appropriate conclusion. Specifically, I illustrate that profit for an exporter is more elastic in response to tariffs than iceberg transport costs, which affects the entry/exit decision of firms. This has implications for welfare analysis and empirical specifications.     

Building the Planning Consensus: The Plan of Chicago,Civic Boosterism,and Urban Reform in Chicago, 1893 to 1915

Since its publication in 1909, Daniel Burnham's Plan of Chicago has been criticized for its lack of attention to social issues and for the failure of subsequent reconstruction projects to live up to the ambition of the plan. These criticisms assume that the Plan of Chicago was insufficiently progressive, or they evaluate the Plan by reference to the successes and failures of subsequent decades of urban reconstruction in Chicago. This article argues that the key to understanding the Plan of Chicago is to place it in its historical context. Burnham's Plan of Chicago was an expression of the tradition of Chicago civic boosterism and earlier city‐building practices as much as it was of the nascent profession of city planning. Finally, while the Plan did neglect housing, poverty, and other social questions, it did possess a social vision based on civic inclusivity, rather than economic inclusivity. The Plan can be read as a reform document based on the assumption that physical environment shapes individual character and social relationships. It assumed the creation of a unified and harmonious physical city would produce a contented and productive citizenry. In short, the Plan of Chicago deployed a transformative vision in the service of conservative goals.     

Non-existence of equilibrium in Vickrey, second-price, and English auctions

A simple example shows that equilibria can fail to exist in second price (Vickrey) and English auctions when there are both common and private components to bidders’ valuations and private information is held on both dimensions. The example shows that equilibrium only exists in the extremes of pure private and pure common values, and that existence in standard models is not robust to a slight perturbation.
