Various alternatives are available when designing a data collection system for portfolio investment (PI) statistics, in the context of balance of payments (BOP) and international investment position (IIP). Such systems differ according to the reporting agents they target, periodicity and level of aggregation, while the corresponding results vary in terms of implementation and running costs, ava...

We develop an equilibrium business cycle model in which the producers of final goods pursue generalized (S,s) inventory policies with respect to intermediate goods, a consequence of nonconvex factor adjustment costs. Calibrating our model to reproduce the average inventory-to-sales ratio in postwar U.S. data, we find that it explains over half of the cyclical variability of inventory investment...

CONDENSED statements of Association finances for the year 1952, prepared by the auditing firm of G. P. Graham & Company, are published herewith, in order that the entire membership may be fully informed regarding the financial operations, obligations, and resources of the AAAS. The first two statements summarize operating receipts and expenditures. Once again the annuity payments to the Cattell...

We expose a theorem of Pila and Wilkie on counting rational points in sets definable in o-minimal structures and some applications of this theorem to problems in diophantine geometry due to Masser, Peterzil, Pila, Starchenko, and Zannier.

William L. Wilkie is Nathe Professor of Marketing, University of Notre Dame (e-mail: [email protected]). How Did This Issue Come About? For much of my career, I have been intrigued with trying to comprehend what the field of marketing is actually about (and what it might be about, what it could be about, what it should be about, and so forth). In recent years, I have joined with my colleague Eliza...

In 1981, Paris and Wilkie [21] indicated it was an open question whether IΣ0 would satisfy the Second Incompleteness Theorem for Herbrand deduction. We will show that IΣ0 will both obey and defy the Herbrandized version of the Second Incompleteness Theorem, depending on which of several equivalent definitions of IΣ0 one examines.

We value the option of subcontracting to improve Þnancial performance and system coordination by analyzing a competitive stochastic investment game with recourse. The manufacturer and subcontractor decide separately on their capacity investment levels. Then demand uncertainty is resolved and both parties have the option to subcontract when deciding on their production and sales. We analyze and ...

This paper aims to explain foreign portfolio investment impact on the dynamics of regional (Central and East Europe) capitalization structure in terms of sectorial investment distribution. Complexity of the problem domain has predetermined the use of interdisciplinary research framework. The ultimate result of this data analysis is a universally applicable model aimed at the nontraditional esti...
