Harmonisation of food regulations and trade in the Single Market: evidence from disaggregated data

A structural gravity model is used to quantify the effect ofharmonisation of EU food regulations on intra-EU trade during1990–2001. We construct a database that identifies foodproducts covered by harmonised regulations at a very detailedlevel. We find, at different levels of aggregation, that harmonisationof food regulations has led to more intra-EU trade, and thatthe tariff equivalents of the cost of not harmonising food regulations,subject to the sub-sector elasticity of substitution, vary significantlyacross some food sub-sectors.

Forty Years of Price Transmission Research in the Food Industry: Insights,Challenges and Prospects: Comment

Lloyd's review of the literature on food price transmission in the Journal of Agricultural Economics (2017) is incomplete in that it omits discussion of technical change and international trade. The purpose of this Comment is to explain why these topics are essential for a proper understanding of price transmission. As a by‐product of the discussion, I show that the pass‐through and pass‐back equations that serve as the basis for Lloyd's theoretical insights are more general than one might think based on Gardner's (American Journal of Agricultural Economics, 1975) discussion of these equations.     

Long-run impacts of trade shocks and export competitiveness: Evidence from the U.S. BSE event

This paper examines how comparative advantages of major beef exporters changed following the 2003 bovine spongiform encephalopathy (BSE) outbreak, which significantly disrupted the U.S. beef trade until approximately 2007. Using longitudinal data on beef export values and constructed revealed comparative advantage measures, we show that while some measures of the long-run impacts of BSE on U.S. beef export competitiveness have returned to pre-2003 levels, the U.S.’s comparative advantage has not. We also examine a hypothetical scenario of no BSE event in 2003 and predict that in the absence of the BSE outbreak, the U.S. beef sector would have been increasingly more competitive by 2017 than it actually was. Long-term trade competitiveness may not simply return to normal even after a short-term disruption.     

Imperfect competition,functional forms,and the size and distribution of research benefits

The effects of functional forms for supply and demand on the size and distribution of the returns to research are examined under a range of forms of competition. Under perfect competition, the choice of functional form is relatively unimportant for the estimation of research benefits. Under imperfect competition, the combination of the choice of functional forms for supply and demand and the nature of the research-induced supply shift can have profound implications for the results. Functional form plays a much more important role than in the competitive model. The most important contrast is between the constant elasticity model and the linear model (along with various cases of a generalized linear model). These findings are illustrated using a combination of analytical results and numerical simulations.     

Tariff Liberalisation,Price Transmission and Rural Welfare in China

China's tariff liberalisation as part of its WTO accession application and eventual agreement has been thoroughly analysed in the literature. However, much of this literature is based on forward‐looking ex‐ante analyses and few studies provide empirical evidence on its actual impact. We fill in this gap by evaluating empirically the welfare effects of China's actual tariff liberalisation on Chinese farmers during the 1997–2010 period. By estimating the domestic market price effects of China's tariff liberalisation and the associated wage earning effects, we find that on average Chinese farmers were able to gain more from reduced consumption prices than they would lose from reduced agricultural and wage income due to tariff liberalisation. Welfare gains over time are estimated to be positively correlated with the actual degrees of tariff liberalisation, implying that relatively more gains were realized immediately before and after China's WTO accession in 2001, as compared to the more recent period when relatively little liberalisation was carried out. Farmers’ rising non‐agricultural income and increasing consumption shares of non‐agricultural products are important determinants of these positive average welfare effects. Moreover, welfare gains from tariff liberalisation are shown to be distributed unevenly across Chinese provinces and income levels, with farmers located in coastal provinces and at higher income levels gaining more than their counterparts in remote provinces and at lower income levels.

Productivity,resource endowment and trade performance of the wood product sector

This paper analyzes the determinants of international trade of wood products, considering three main groups: woodworking products, pulp and paper and wooden furniture. We extend the Heckscher-Ohlin-Vanek (HOV) framework in order to take into account the forest resource endowment as well as industrial performance factors. Empirical tests are based on data on European countries between 1995 and 2007. The HOV hypothesis is partially confirmed in that the forest resource endowment is a significant determinant for explaining differences in net trade of two products (pulp and paper and furniture) but not for woodworking products. In addition, empirical tests also show the limits of the HOV model for explaining international trade of wood products. Indeed, factors reflecting industrial performance of wood sectors, including total factor productivity and average labor cost, have a significant role in determining differences in net trade of wood products.

Balancing economic revenue and grazing pressure of livestock grazing on the Qinghai–Tibetan–Plateau

Treating grazing pressure as an undesirable output of livestock grazing in a directional distance function improves understanding of how economic behaviour affects the environment. Field survey data from 193 livestock grazing households combined with remotely sensed net primary productivity (NPP) data on the Qinghai–Tibetan–Plateau was used to develop a directional output‐orientation distance function. The average efficiency of livestock grazing households is 0.817 when incorporating grazing pressure as an undesirable output, which means that households can achieve 18.3% more output and decrease proportional grazing pressure holding all inputs fixed. The relative shadow price of undesirable grazing pressure to good output grazing revenue is estimated to be between 1.795 and 3.986. According to the Morishima elasticity of substitution between inputs, there is a significant complementary relationship between grassland, labour and capital.     

An analysis of population growth,Green Revolution and terms of trade in the presence of cropsharing in agriculture

This explores the welfare effects of some persistent trends in some developing countries on different groups of farmers. It takes a general equilibrium approach in modelling a representative developing economy comprising a manufacturing sector and an agricultural sector where both self-cultivating landlords and tenants carry on production. It is shown that while population growth tends to depress welfare of both the tenant and the landlord, Green Revolution has the opposite effect such that when both trends are present, peasants may or may not be better off. An adverse movement in the agricultural terms of trade reduces welfare of the landlord, but the tenant is made better off.     

中德两国木质家具出口贸易的比较研究——基于1997--2009年数据的实证分析

通过1997--2009年的贸易数据对中德两国的木质家具出口贸易进行了比较研究。利用CMS模型测算了拉动两国木质家具出口增长的原因,进而通过显性比较优势指数和贸易结合度指数的测算,实证分析了中德两国各自具有比较优势的产品类型以及双边木质家具贸易的结合程度。结果发现,竞争力效应和一般增长效应分别是拉动中国和德国木质家具出口增长的主要因素,两国分别在不同种类的产品上具有比较优势且两国问的木质家具贸易结合程度不高,具有巨大的合作发展潜力。     

中国木质家具出口贸易与汇率波动关系研究

木质家具是我国最重要的出口林产品之一。人民币汇率改革后,人民币总体呈升值趋势,这一趋势提高了国产木质家具的出口价格,会产生阻碍出口的作用;与此同时其也会使进口原材料价格相对降低、促进原材料的进口,二者相互作用会共同影响木质家具出口额。通过建立回归模型,研究人民币汇率波动对中国木质家具出口贸易额的影响,结果表明人民币汇率与中国木质家具出口额呈负相关,但是通过人民币贬值来促进出口的策略并不明智。     

The effects of the Yuan‐dollar exchange rate on agricultural commodity trade between the United States,China, and their competitors

The United States claims that the undervaluation of Chinese currency, the Yuan, causes U.S. exports to China to decrease and imports from China to increase. Furthermore, because the Yuan is undervalued only against the dollar, U.S. competitors have an advantage in exporting to China and China has an advantage over its competitors in exporting to the United States. This study develops a theoretical model to analyze the effect of the Yuan undervaluation on prices, supply, demand, and trade in the United States, China, and their competitors. This study applies a cointegration/error‐correction model to empirically quantify the short‐run and long‐run effects of the devaluation of the Yuan on important agricultural commodities traded between the United States, China, and their competitors. These commodities include Chinese imports of milk, soybeans, and cotton from the United States and U.S. imports of beans, fruit juice, and fruit from China. The results show that Yuan devaluation causes Chinese imports of U.S. milk, soybeans, and cotton to decline and U.S. imports of beans, fruit juice, and fruit from China to increase in the short run and in the long run.     

Marketing and Pricing Dynamics in the Presence of Structural Breaks: The Hungarian Pork Market

The study of marketing margins and price transmission on various commodity markets has been a popular research topic of the past decades (see Meyer & Von Cramon-Taubadel, 2004 Meyer , J. , & Von Cramon-Taubadel , S. ( 2004 ). Asymmetric price transmission: A survey . Journal of Agricultural Economics , 55 ( 3 ), 581 – 611 .[Crossref], [Web of Science ®] , [Google Scholar], for a recent survey). However, with a few exception these studies focused on developed economies. This article examines this phenomena on the Hungarian pork market. The Johansen (maximum likelihood, 1988 Johansen , S. ( 1988 ). Statistical analysis of cointegrating vectors . Journal of Economic Dynamics and Control , 12 , 231 – 254 .[Crossref], [Web of Science ®] , [Google Scholar]) or Engle and Granger (2-step, 1987 Engle , R. F. , & Granger , C. W. J. ( 1987 ). Cointegration and error correction: Representation, estimation and testing . Econometrica , 55 , 251 – 276 .[Crossref], [Web of Science ®] , [Google Scholar]) cointegration tests do not reject the no-cointegration null hypothesis between the Hungarian pork producer and retail price series. Therefore, we applied the Gregory and Hansen (1996 Gregory , A. W. , & Hansen , B. E. ( 1996 ). Residual-based tests for cointegration in models with regime shifts . Journal of Econometrics , 70 , 99 – 126 .[Crossref], [Web of Science ®] , [Google Scholar]) procedure with recursively estimated break points and Augmented Dickey Fuller (ADF) statistics and found that the prices are cointegrated with a structural break occurring in April 1996 Gregory , A. W. , & Hansen , B. E. ( 1996 ). Residual-based tests for cointegration in models with regime shifts . Journal of Econometrics , 70 , 99 – 126 .[Crossref], [Web of Science ®] , [Google Scholar]. Exogeneity tests reveal the causality running from producer to retail prices both in the long and short run. Homogeneity tests are rejected, suggesting a markup pricing strategy. Price transmission modeling suggests that price transmission on the Hungarian pork meat market is symmetric in the long run but asymmetric in the short run; that is, processors, wholesalers, or retailers might take temporary advantage should price changes occur.     

Reputations, Market Structure, and the Choice of Quality Assurance Systems in the Food Industry

Many food traits desired by consumers are costly to provide and difficult to verify. A complicating factor is that delivered quality can only be affected stochastically by producers and imperfectly observed by consumers. Markets for these goods will emerge only if supplying firms can be trusted. We develop a repeated purchases model to explore how quality discoverability, market structure, nature of reputations, market premiums, and discount factors drive firm choice about the stringency of quality assurance systems designed to gain consumer trust. Reputation protection is key incentive for firms to invest in high-quality goods and quality assurance systems.
