t his paper investigates the gain of bilateral trade between china and u.s. in manufacturing sectors when both countries play a role in asymmetric (biased) growth of  international trade. our model includes a special case of biased growth theory in international trade. we collected labor productivity, export and import data by using classification of manufacturing industries, for u.s. and china...

Many livestock sector models have limited coverage of relevant variables, and are somewhat ad hoc in their choice of what should be specified as behavioral equations. This study develops a generic conceptual approach to modeling the livestock sector that provides consistent rules of specification and better coverage of variables. This approach is then applied to the swine-pork sector of Japan. ...

Advisor: Azzeddine Azzam While technically considered as fungi, mushrooms are often classified as vegetables because they provide many of the nutritional attributes of produce as well as meat, beans, and grains. The U.S. is the largest consumer of mushrooms and the share of imports in total consumption of mushrooms has been rising and will likely continue to The contribution of this thesis is t...

the aim of this paper is to present the prediction model of the transport energy demand in iran. markov chain grey model (mcgm) is proposed to forecast the transport energy demand of iran. then it is compared with grey model (gm) and regression model. moreover, the mcgm forecasting model is used to forecast the annual gasoline demand of iran up to the year 1400. the aim of this paper is to pres...

The United States has been increasing the import of wooden bedroom furniture from the world to meet its domestic needs. Traditional suppliers have been substituted by developing countries such as China and Vietnam over the past decade. To explain this market structure change, a dynamic Almost Ideal Demand System (AIDS) was employed to analyze this import market. Monthly import data of the top s...

the sources of output growth of iranian agriculture over the years 1986-2001 has been examined, using a decomposition method within the input-output (io) framework. the three comparable io tables of 1986, 1991, and 2001 have been employed as the main data sources. output changes from a demand side perspective, and decomposition of the growth of output into components attributable to consumption...

A queuing model is introduced for estimating container flow times through port terminals as a function of infrastructure, staffing, and import volume. The model is statistically calibrated on industry data. Flow-time estimates of the model are aggregated with estimates from models previously developed for rail networks to develop estimates of the total container flow times from West Coast ports...

The attempt in this study has been to detect the influence of foreign exchange reserves on import demand Nigeria. With data spanning from 2000 2020, we estimated long-run and short-run function using ‘fully modified ordinary least squares’ ‘error correction model’ respectively after established that our variables were integrated first order cointegration exists. pointed out effect is positive b...

among the food products, grains play an important role in the consumption patterns of people, especially in the developing countries. since iran's main source of public dietary energy comes directly from grains, investigating and identifying the determinants of import of these products can be an important step towards food security. most experimental studies consider import of grains as only a ...

this paper estimates the determinants of inflation in iran using a linear and non- linear regression model over the period 1959-2008. in the model specification, the conventional variables (liquidity, production and exchange rate) as well as positive and negative oil revenue shocks, monetary disequilibrium, and demand gap are considered. the results show that nonlinear time series regression mo...
