  • Emerging Markets for US Pork in China: Experimental Evidence from Mainland and Hong Kong Consumers

    David L. Ortega, Maolong Chen, Satoru Shimokawa, H. Holly Wang

    JOURNAL OF AGRICULTURAL AND RESOURCE ECONOMICS   42 ( 2 ) 275 - 290  2017年05月  [査読有り]

     概要を見る

    A major concern for international marketers is how products will be received by foreign consumers in other markets. This study uses choice modeling to assess Chinese consumer preferences for pork and evaluate the potential demand for U.S. pork in the cities of Guangzhou and Hong Kong. We find that differences in preferences for domestic versus imported pork can be explained, in part, by consumers' level of patriotism. Marketing pork with a food safety claim can increase market demand for U.S. products, and accounting for differences in nationalistic attitudes can aid marketing efforts.

  • Why can calorie posting be apparently ineffective? The roles of two conflicting learning effects

    Satoru Shimokawa

    FOOD POLICY   64   107 - 120  2016年10月  [査読有り]

     概要を見る

    We investigate why the aggregate effect of calorie posting on calorie consumption can be insignificant by decomposing the learning effect into two conflicting components: a calorie-decreasing effect of learning that one was underestimating caloric content (LUE), and a calorie-increasing effect of learning that one was overestimating caloric content (LOE). Our lab snack-order experiments demonstrate the existence of the LUE effect (-8.3%) and the LOE effect (+4.8%), where the aggregate learning effect is -5.8%. Our results also imply that the LUE can be cancelled out by a positive saliency effect, while the undesirable saliency effect may be mitigated by combining the calorie posting with information about daily calorie needs.

  • Nutritional impacts of rising food prices in African countries: a review

    Xiaohua Yu, Satoru Shimokawa

    FOOD SECURITY   8 ( 5 ) 985 - 997  2016年10月  [査読有り]

     概要を見る

    This paper investigates the influences of food price spikes on nutritional outcomes in six African countries: DR Congo, Ethiopia, Malawi, Nigeria, Tanzania, and Uganda. Drawing on the estimates of food demand elasticity with respect to food prices in previous studies, we constructed the elasticity of calorie and protein consumption with respect to food prices. We find that, while increasing cereal prices has the largest negative influences on both calorie and protein consumption in all the countries, the magnitude of the influences may differ by regions and the country's dietary patterns. The negative influences are particularly large in rural areas and in the countries whose diets highly depend on a single staple cereal while small in the countries whose diets have alternative staple foods. Our findings highlight the importance of stabilizing cereal prices to reduce calorie deficiency while it may not be enough to improve protein deficiency.

  • Sustainable meat consumption in China

    Satoru Shimokawa

    JOURNAL OF INTEGRATIVE AGRICULTURE   14 ( 6 ) 1023 - 1032  2015年  [査読有り]

     概要を見る

    Sustainable meat consumption is critical to achieve a sustainable food system because meat products are among the most energy-intensive, ecologically burdensome, and ethically concerned foods. This paper focuses on the case of China and discusses the difficulties and possibilities to achieve sustainable meat consumption in China by reviewing previous empirical studies and descriptive statistics, particularly considering consumers' dietary transitions in quantity and quality following China's rapid economic growth. Given China's sheer size of population and meat demand, the sustainable meat consumption in China is also a relevant topic in the global food system.

  • Nutrient Intake of the Poor and its Implications for the Nutritional Effect of Cereal Price Subsidies: Evidence from China

    Satoru Shimokawa

    WORLD DEVELOPMENT   38 ( 7 ) 1001 - 1011  2010年07月  [査読有り]

     概要を見る

    We incorporate habit formation into an analysis of the effect or cereal price changes on the nutrient intake of the poor in China. We find that the poor's nutrient intake responds asymmetrically to declines and increases in cereal prices, and that the asymmetric response of their fat intake may be due to habit formation. Our results also imply that introducing cereal price subsidies can increase their total energy intake by increasing their calorie intake from fat and protein, while ending such subsidies would insignificantly affect their total energy intake, but further increase their calorie intake from fat and protein.

  • ASYMMETRIC INTRAHOUSEHOLD ALLOCATION OF CALORIES IN CHINA

    AMERICAN JOURNAL OF AGRICULTURAL ECONOMICS   92 ( 3 ) 873 - 888  2010年04月  [査読有り]

     概要を見る

    To analyze intrahousehold calorie allocation, we propose a new framework that takes into account asymmetric consumption behavior due to liquidity constraints and loss aversion We find that intrahousehold calorie allocation responds asymmetrically to expected declines and increases in household food availability in China Compared with previous studies based on symmetric consumption behavior, our framework provides stronger evidence of gender bias in intrahousehold calorie allocation among children in urban areas and among elderly people in rural areas, and of demographic bias between girls and prime-age adults in both urban and rural areas. Implications for demographic targeting in nutrition programs are discussed

  • Understanding the differences in obesity among working adults between Taiwan and China

    Satoru Shimokawa, Hung-Hao Chang, Per Pinstrup-Andersen

    ASIA PACIFIC JOURNAL OF CLINICAL NUTRITION   18 ( 1 ) 88 - 95  2009年  [査読有り]

     概要を見る

    Objective: To investigate the difference in the prevalence of obesity and the associations between the risk of obesity and socioeconomic factors with regard to working adults in China and Taiwan. Data: the 2000 China Health and Nutrition Survey and the 2001 National Health Interview Survey in Taiwan, which contains information from 20-60-year-old working adults in China (3,067 men and 2,998 women) and Taiwan (6,475 men and 6,341 women). Method: Variables were converted to cross-economy comparable forms, and the estimated prevalence of obesity across socioeconomic groups was compared between China and Taiwan. Probit models were used to examine the associations between socioeconomic factors and the probability of being obese. Results: In China, the prevalence of obesity was higher in the higher income, more educated, and more sedentary occupation groups, while it was higher in the lower income and less educated groups in Taiwan. Also, our results indicate that occupational types rather than income and education levels are more significantly associated with the probability of being obese in China, whereas income and education levels rather than occupational types are more significantly associated with the probability of being obese in Taiwan. These findings may indicate that, when an economy becomes more developed, the association between obesity risk and income and education levels becomes more significant and negative especially among women, while the association between obesity risk and occupational types decreases especially among men.

  • Do poverty and poor health and nutrition increase the risk of armed conflict onset?

    Per Pinstrup-Andersen, Satoru Shimokawa

    FOOD POLICY   33 ( 6 ) 513 - 520  2008年12月  [査読有り]

     概要を見る

    We analyze the effects of improving the economic, food security and health status on the risk of armed cotntectflict onset, focusing on the factors related to the millennium development goals. We employ the discrete-time hazard model that allows us to examine the time-varying effects of socioeconomic factors controlling for the reverse effect of conflict. Our results show that income poverty and poor health and nutritional status are more significantly associated with armed conflict onset than GDP per capita, annual GDP growth. and the ratio of primary commodity exports over GDP. In particular, poor health and nutritional status seems to play a key role in inducing armed conflicts in Poor Countries. These results indicate that, when a majority of the poor and the malnourished resides in rural areas and depends on agriculture directly or indirectly, investments in public goods for agriculture and rural areas can be effective tools to achieve the multiple goals of reduced poverty, food security and armed conflict, including riots in early 2008 triggered by high food prices. Food policy can be an effective element of efforts to maintain stability. (C) 2008 Elsevier Ltd. All rights reserved

  • The labour market impact of body weight in China: a semiparametric analysis

    Satoru Shimokawa

    APPLIED ECONOMICS   40 ( 8 ) 949 - 968  2008年  [査読有り]

     概要を見る

    While a positive wage effect of Body Mass Index (BMI) is widely observed in low-income developing countries, a negative wage effect of BMI is often observed in high-income developed countries. To fill the gap between these previous findings, we investigate the relationship between body weight and wages in transition economies. We focus on China, whose rapid economic growth of the 1990s was followed by a rapid increase in overweight and obesity while still experiencing significant food insecurity and underweight. we first use several parametric regression strategies to obtain a consistent estimate of the wage effects of weight. Second, we adopt a semiparametric partially linear model that allows for endogeneity of weight. Parametric regressions provide mixed results, and the sign and magnitude of their estimates are sensitive to the choice of samples and regression strategies. Semiparametric estimates provide evidence of a wage penalty for very heavy and thin persons among both men and women. The wage penalty is more significant among men than among women. Semiparametric results also indicate that parametric estimates can overstate and misrepresent the wage effects of weight for healthy weight persons due to their restrictive functional form assumptions.

  • Impact of Cultivated Land Conversion on Food Security in China

    2016年  

     概要を見る

    In China, the steep rise in cultivated land conversion, accompanied by a population increase, has provoked the debate about its impact on food security. Accordingly, the Chinese government emphasizes the importance of retaining cultivated land. However, it is still controversial if cultivated land conversion really threatens China’s food security. Thus, this study investigates the causal impact of cultivated land conversion on grain output in China by employing the instrumental variables estimation. Our estimation strategy exploits the facts that tax reform (a change in the enterprise tax-sharing scheme) and administrative decentralization in 2002 unintentionally influenced farmland conversion and that the magnitude of the unintended influences varied across local governments depending on how much their tax revenues had depended on the enterprise tax before the reform. Using data from 1999 to 2005, we found that land conveyance area significantly increased as local governments’ fiscal revenue decreased, and a decrease in farmland area caused by the land conveyance decreased grain output. Even after controlling for potential endogeneity bias, a 1% decrease in local government’s fiscal revenue increased land conveyance areas by 3.4%, and it decreased grain output by 0.10%. The findings may moderately support China’s recently imposed “redline” of 120 million hectares of cultivated land.
