China has the highest pork consumption in the world. As incomes increase and the urbanization process accelerates, the consumption of pork by Chinese residents will continue to grow. This paper studies the proportion of the household pork consumption account and examines the use of apparent pork consumption as a bridge that links consumption and production. Based on the pork consumption of urba...

the aim of this study is to assess cost-effectiveness of infliximab, compared with conventional treatments in patients with moderate to severe ulcerative colitis (uc) in iran. we developed an analytical decision model with a 5-year-time horizon to follow up 1000 hypothetical patients, in order to estimate treatment costs and outcomes. hypothetical patients, were individuals with moderate to sev...

Scale effects in per capita production are an outcome of many theoretical economic models like second generation growth models, models of the new trade theory or the new economic geography. The prediction is that larger economies should have a higher per capita production than smaller economies. However, in an open economy context the scale of the economy is less important because countries can...

The maximum per capita rate of population growth, r, is a central measure of population biology. However, researchers can only directly calculate r when adequate time series, life tables and similar datasets are available. We instead view r as an evolvable, synthetic life-history trait and use comparative phylogenetic approaches to predict r for poorly known species. Combining molecular phyloge...

This study investigates the responsiveness of manufacturing sector performance to major macroeconomic determinants in Nigeria, covering the period between 1981 and 2018. It contributes to attendant literature by examining the asymmetric impact of each of the macroeconomic variables, including GDP per capita, exchange rate, inflation rate, interest rate proxied by prime lending rate, and gross f...

Rice comes second after wheat in Iran`s food consumption economy. However Iran is one of the greatest rice importer countries all over the world because of its rising population and recent growth in GDP. This paper presents an analysis of cointegration test between rice import and it`s economic factors over the period 1990-2011, employing Engle-Granger model. At first, Dickey-Fuller test shows ...

T his study investigated the effect of international labor migration on Iran’s economy using a neo-classical growth model with the assumption of labor heterogeneity within the framework of dynamic stochastic general equilibrium model. After solving the model, the obtained equations were linearized and different values were assigned to the parameters according to Iran’s economy inform...

BACKGROUND In the United States, traffic fatality rates per distance driven vary greatly from state to state, with the maximum rate being 2.9 times the minimum rate. This study was designed to examine factors associated with this variability. METHOD A multiple regression was performed on the 2006 state data. The dependent variable was the fatality rate per distance driven. There were 10 indep...

In this work, nonlinear pollution absorption, emission rate, and effectiveness of abatement technology are incorporated into the classic overlapping generation model. Within this framework, we analyze the macroeconomic effects of pollution emission and abatement technology on the economy. Our findings reveal that different levels of pollution emission rates from per capita income and the effect...

ICAR Technical Series No 3 In the last two decades total milk production has almost doubled while the heads of cattle have increased by 28 percent in developing countries (FAO, 1999). There is a large variation among regions. The Far East region shows the sharpest production increase, also per capita, while Africa and the Near East show the largest increase in heads of cattle but a continuous d...
