Locally Coherent Rates of Exchange

Computing Locally Coherent Discourses

We present the first algorithm that computes optimal orderings of sentences into a locally coherent discourse. The algorithm runs very efficiently on a variety of coherence measures from the literature. We also show that the discourse ordering problem is NP-complete and cannot be approximated.

Nonlinearity In Exchange Rates and Forecasting

Exchange rates.

THE UNIVERSITY of Pennsylvania health system was in London recently, recruiting nurses. Its advertisement stated that its recruiters were experienced in hiring nurses from the UK, Ireland and the Philippines, and an 'on the spot job offer is a possibility'. This one advert neatly captures the dynamics of the new international nursing labour market. The advert was placed by an international recr...

A Locally Cache-Coherent Multiprocessor Architecture

Recently there has been considerable interest in cache coherency protocols in shared-memory multiprocessor systems, particularly in protocols which are scalable, i.e. suitable for very large systems. However, cache coherency scalability (CCS) entails heavy performance overhead and system cost, so a critical examination of the assumptions underlying the quest for CCS is undertaken here. A non-CC...

Forecasting Disconnected Exchange Rates

Catalyzed by the work of Meese and Rogoff (1983), a large literature has documented the inability of empirical models to accurately forecast exchange rates out-of-sample. This paper extends the literature by introducing an empirical strategy that endogenously builds forecast models from a broad set of conventional exchange rate signals. The method is extremely flexible, allowing for potentially...
