T he United States, along with almost every other country in the world, maintains significant restrictions on the movement of goods across international borders. Although the recent Uruguay round of the General Agreement on Tariffs and Trade (GATT) resulted in a general lowering of tariffs and a broadening of goods and countries covered by the agreement, free trade remains elusive. Strong growt...

Do conflicts among naval powers hurt international trade? In theory the commercially relevant aspects of aggressive naval power can either thwart trade (through blockades, embargoes, commerce raiding, and guerre de course strategies) or facilitate trade (through control of trade routes and protection of shipping). Thus the question must be empirically addressed. Using a panel gravity model, we ...

Hemoglobin is a tetrameric oxygen transport protein in animal bodies. However, there is a paucity of information regarding differences between alpha and beta subunits of hemoglobin in terms of oxygen affinity. The sequential model of Koshland, Nemthy and Filmer (KNF model) has attributed similar affinities to both alpha and beta subunits. The main purpose of the present study is to construct a ...

Firms need to incur substantial sunk costs to break in foreign markets, yet many give up exporting shortly after their first experience, which typically involves very small sales. Conversely, other new exporters shoot up their foreign sales and expand to new destinations. We investigate a simple theoretical mechanism that can rationalize these patterns. A firm discovers its profitability as an ...

This paper estimates the impact of the ASEAN-China Free Trade Agreement on the trade flows between China and the ASEAN countries. A gravity model with FTA specification is used to estimate the treatment effect of ACFTA. Since there are other unobserved variables that correlate with both the trade flows between China–ASEAN and the decision to form ACFTA, a cross-sectional OLS regression runs the...

the role of distance as border effects between trade partners has been created challengeable discussions in gravity model literature for international economists and lead to different theoretical aspects for measuring and modeling of it in recent years. moreover, the necessity of non-linear method for estimation of gravity model has been perfectly agreed. the importance of this study is the est...

Title of dissertation: SEQUENTIAL DECISIONS AND PREDICTIONS IN NATURAL LANGUAGE PROCESSING He He, Doctor of Philosophy, 2016 Dissertation directed by: Professor Hal Daumé III Department of Computer Science Natural language processing has achieved great success in a wide range of applications, producing both commercial language services and open-source language tools. However, most methods take ...

We propose a simple higher-derivative braneworld gravity model which contains a stable accelerating branch, in the absence of cosmological constant or potential, that can be used to describe the late time cosmic acceleration. This model has similar qualitative features to that of Dvali-Gabadadze-Porrati, such as the recovery of four-dimensional gravity at subhorizon scales, but unlike that case...
