Surprisingly, nearly every school district that utilizes a centralized assignment procedure makes a Pareto inefficient assignment. The two objections to the standard efficient algorithm, Top Trading Cycles (TTC), are that it makes unfair assignments and that it allows students to trade school-specific priorities. This paper identifies two shortcomings of TTC: students may trade even after they ...

This paper examines the composition of trade between the United States and eight Asian Pacific economies from 1962 to 1992. Analysis of the time series pattern of individual commodities at the SITC four-digit level reveals economically significant changes in the pattern of trade, reflecting changing comparative advantage based on changing factor proportions, technology transfer and product cycl...

Abstract— In this paper we study the energy consumption in optical networks. We propose a cluster based architecture for minimizing the energy consumed in transparent optical networks. The network topology is partitioned as disjoint clusters and nodes in the clusters adopt sleep cycles. Using anycast routing, we obtain a trade-off between the energy consumption and the average requests lost due...

We consider a multi--sector overlapping generations model with imperfectly competitive firms in the output markets and wage setting trade unions in the labour markets. A coordination problem between firms creates multiple temporary equilibria which are either Walrasian or of the Keynesian unemployment type. There exist many deterministic and stochastic equilibrium cycles fluctuating between Key...

Bringing efficiency to the entire trade lifecycle is the key to decreasing risk. With increased cross border trade activities, the post trade process continues to be complex and challenging for investment firms due to lack of harmonization in market practices. Despite technology advances and business process improvements, there are inefficiencies in the settlement process leading to trade and s...

Although seasonality is widespread and can cause fluctuations in the intensity and direction of natural selection, we have little information about the consequences of seasonal fitness trade-offs for population dynamics. Here we exposed populations of Drosophila melanogaster to repeated seasonal changes in resources across 58 generations and used experimental and mathematical approaches to inve...
