هدف این مقاله بررسی امنیت غذایی خانوارهای شهری در ایران و عوامل مؤثر بر آن طی سال های 1390 – 1362 است. بدین منظور، از الگوی سری زمانی برای ارزیابی عوامل موثر استفاده شد. نتایج نشان داد طی سال های مورد بررسی، امنیت غذایی خانوارهای شهری، صعودی بوده است. علی رغم بهبود امنیت غذایی در سطح شهرها، در سال 1390، 1/5 درصد از جمعیت شهری، کمتر از میزان استاندارد، انرژی دریافت کرده اند. اثر درصد جمعیت شهرنش...
Abstract This article provides an empirical case study of the impacts COVID-19 pandemic on global beverage markets, particularly wine sector. Both international trade and domestic sales have been adversely affected by temporary shifts away from on-premise social distancing measures self-isolation that led to closure restaurants, bars, clubs, plus declines in travel tourism. Partly offsetting th...
This paper deals with the quantification of GMO regulations on bilateral trade flows. A composite index of the ‘complexity’ of such regulations for sixty countries as well as an ‘objective’ score for six GMO regulatory sub-dimensions has been developed. Using a gravity model, we show how bilateral ‘similarity’ in GMO regulations, affect trade flows for the composite index and its components. Re...
We revisit the cost of the U.S. sugar program by analyzing the welfare implications of its removal. We use a multimarket model of U.S. sweetener markets, which includes raw crops, sugar extraction and refining, high-fructose corn syrup, and sweetener users (food-processing industries and final consumers). Our approach addresses the industrial organization of food industries using sweeteners and...
Using a bilateral trade equation derived from a monopolistic competition model, we investigated market access reciprocity in food trade among the US, Canada, the EU and Japan. We explore country and industry–specific market access asymmetry through the border effect approach, re-challenging the underlying main explanations. Our findings reveal marked asymmetry in reciprocal trade openness; inde...
The effects of the institutional determinants on trade in agricultural and food products are analyzed using a gravity model approach. We focus on the impact of the quality of governance and the similarity of institutions in explaining variation in bilateral agricultural and food trade patterns among the OECD countries. Results confirmed the separate effects for the institutional similarity and ...
How large are the welfare gains from trade when factors are misallocated due to domestic distortions? In this paper I provide a quantitative answer to this question by incorporating distortions to the allocation of labor across broad sectors into a model of structural change and Ricardian trade. Calibrating the model using 36 years of data for a diverse set of countries I find that (1) gains fr...
In this paper, two key questions are asked: why has the GATT/WTO worked in terms of multilateral tariff reduction and promotion of global trade, and to what extent will it act as a constraint on economic nationalism? To answer these two questions, three themes are laid out in the paper: first, the seminal economic model rationalizing the economic logic of the GATT/WTO is assessed; second, the p...
This paper adds to the existing literature on the estimation of future consumption patterns. I first forecast the demand of beef, chicken and pig products for the years 2020 and 2040 using a simultaneous equations model for the world and specific regions. Then, using existing research on “best existing case” scenarios of the ecological impact of different foods, I estimate the land usage and gr...
هدف مقاله برآورد عوامل مؤثر بر عرضه چای استان گیلان با استفاده از اطلاعات سری زمانی دوره 1390- 1360 در قالب الگوی «نرلاو» می باشد. بر اساس نتایج، متغیرهای توضیحی مدل توانستند 97 درصد تغییرات متغیر وابسته (عرضه محصول) را توضیح دهند و نتایج نشان داد شاخص قیمت تضمینی برگ سبز چای با میزان کشش 81/0 از حساسیت بیشتری برخوردار است. همچنین عرضه چای با یک وقفه زمانی با میزان کشش 60/0 و فنّاوری نیز با میزا...
