Economists and other social scientists are calling for a reassessment of the impact of international trade on labor markets in developed and developing countries. Classical models of globalization and trade, based upon the international exchange of finished goods, fail to capture the fragmentation of much commodity production and the geographical separation of individual production tasks. This ...

Wireless Sensor Networks (WSNs) are made up of small nodes which have the ability to sense, compute and communicate wirelessly. Essential design issue in WSN routing is energy awareness as the sensors are energy constrained. Various routing, power management and data dissemination protocols designed for WSNs are available in the literature. Energy awareness and reliable data transmissions are h...

Energy-efficient forwarding becomes important if resources and battery lifetime are limited such as in Wireless Sensor Networks. Although widely used, simple hop-based forwarding along a path from one node towards a sink can be very inefficient in terms of delivery rate as well as energy efficiency, especially in lossy environments. We will show that just minimizing the expected number of trans...

I present a three player dynamic network theoretic model where players are farsighted and asymmetric. Unlike the previous literature that imposes an exogenous protocol governing the order of negotiations, I allow the identity of the players who form a link in a given period to depend endogenously on player characteristics. Importantly, I show how this can give di erent predictions regarding att...

Rising wage inequality and increasing international trade have renewed interest in the empirical relevance of the Stolper-Samuelson theorem. Although a brilliant theoretical accomplishment, the Stolper-Samuelson theorem has received little empirical support. U.S. studies have generated mixed results partially because prices are endogenous in a large country. This paper examines the link between...

[1] ABSTRACT II. SERIALIZER STRUCTURE Analytical model is employed to characterize and compare serial and parallel communication techniques in NoC interconnect. Simulations that are based on 130nm and 70nm technology parameters reveal up to ×5.5 and ×17 reduction in power and area of serial vs. 32-bit multi-layer parallel link, respectively. Lower power is dissipated by a single-layer parallel ...

Analysis of senescent Escherichia coli cells reveals a link between protein oxidation and the fidelity of the translational apparatus. This model system has also provided a mechanistic molecular explanation for a trade-off between reproduction and survival activities, which may inspire proponents of the disposable soma theory and antagonistic pleiotropy hypothesis of aging.

This paper offers new insights on a central question in trade and development economics: does increased exposure to foreign competition generate gains in plant productivity? We find that it does. We examine Colombian trade policy from 1977 to 1991, a period during which trade liberalization alternates with increased trade protection in varied ways across industries, to investigate the link betw...

We demonstrate that simply by using the ethnic makeup surrounding a firm’s location, we can predict, on average, which trade links are valuable for firms. Using customs and port authority data on the international shipments of all U.S. publicly-traded firms, we show that firms are significantly more likely to trade with countries that have a strong resident population near their firm headquarte...
