Summary: Estimating the relationship between income growth and food/nutrient demand in China, the study found that there are significant differences in the size of the income elasticities across food and nutrient groups. It also found that food- and calorie-income elasticity appear to decline as per capita income increases, except for vitamin and aquatic products.

Summary: This paper reexamines the literature on money demand in China, published in both English and Chinese, over the past 30 years. The focus of the literature has been on income elasticity, stability, and the choice and quality of data, which is particularly important for China. The paper finds a substantial publication bias towards rejecting stability in money demand, but when controlling for this bias and looking at longer time periods, it strongly suggests a stable long-run money demand in China.

Summary: This paper updates and extends the systematic review and meta-analysis of the impacts of punctuality on passenger rail demand, adding more recent British studies to the analysis. The findings suggest that there is uncertainty regarding the definition of long run impacts, and rail industry guidance may tend to overstate the demand impacts of punctuality.

Summary: How advertising affects supply and demand in the entertainment industry is examined through a meta-analysis of 290 elasticities from 59 studies of movies and video games. The study finds that the average advertising elasticity in the entertainment industry is three times higher than in other industries, and that demand elasticities are higher than supply elasticities. Pre-launch advertising has higher elasticities than overall advertising budgets, with later periods showing higher elasticities compared to the launch period. Elasticities are consistent across geographic regions but have decreased after the rise of social media platforms.

Summary: The income elasticity of consumption is not only influenced by the demand function, but also by the characteristics of the supply function. When the supply of the underlying good is not completely elastic, the income elasticity of equilibrium consumption will be less than the income elasticity of demand, with the difference depending on the shapes of both the demand and supply functions.

Summary: The study reveals that the harvested area of tropical crops has more than doubled since 1961, with increasing intensification. The impact of tropical agriculture on biodiversity is determined by crop type, rotation time and level of shading.

Summary: Environmental merits are a common motivation for urban agriculture projects, and life cycle assessment (LCA) is used to quantify environmental impacts. Recent LCAs of urban agriculture have shown mixed conclusions about their environmental performance. Issues with quality, consistency, and data variability in LCAs prevent definitive conclusions about the environmental impacts and resource use of urban agriculture.

Summary: This study examined the price elasticity of medicine demand in different therapeutic drug categories and types in China, finding variations in elasticity across drug categories and the impact of quality differences, unfair competition, and illegal rebates on price elasticity. The results showed that anti-tumor and CVD drugs had the least elasticity, while antimicrobial drugs had the most elasticity. This study highlights the role of disease type and drug quality in shaping price elasticity in the Chinese medicine market.

Summary: This meta-analysis reveals a prevalence of resistance to tetracycline (TET) and third generation cephalosporins (3GC) in Enterobacteriaceae isolated from food crops. The study highlights the importance of monitoring antimicrobial resistance (AMR) in food crops, particularly for 3GC which has limited agricultural usage. Harmonized sampling methods could confirm the trends observed and contribute to One Health AMR surveillance.

Summary: This study examines regional heterogeneity in food consumption patterns in Indonesia. The authors estimated the demand system for key food commodities in five regions using household data and a two-step budgeting procedure based on the Quadratic Almost Ideal Demand System (QUAIDS) framework. The results reveal significant differences in elasticities across regions, indicating the importance of considering regional heterogeneity when estimating demand structures. Furthermore, a welfare impact analysis demonstrates that ignoring regional heterogeneity can lead to overestimation or underestimation of welfare loss caused by price increases.

Summary: The transformation of dietary structure brought about by economic development in populous countries is expected to increase pressure on grain supply. The study based on China's dataset predicts a significant difference in grain demand, with potential implications for the goal of 95% grain self-sufficiency. The paper emphasizes the importance of understanding the supply-demand gap and trends to support national and global food security.

Summary: The study found that the demand for processed food exports from developing countries is more influenced by income and less by price. This suggests that demand expansion for imports is primarily driven by income growth.

Summary: The impact of improved agricultural practices and technologies on smallholder farmers' welfare has been widely examined. This study conducted a meta-analysis of 52 studies in Africa and found that factors such as data type, model specification, sample size, region, and journal type explain the differences in reported technology adoption effects. The study provides valuable information for designing policy interventions in the African context.

Summary: Thailand is the world's largest natural rubber exporter, and the rubber industry plays a crucial role in both the national economy and the livelihood of farmers. The increasing reliance on monoculture rubber plantations presents sustainability challenges due to negative impacts of homogenous cropping systems. Rubber crop diversity systems are seen as a solution to environmental degradation and securing farmers' income, but adoption among most rubber farmers in Thailand is complex. Factors influencing adoption include management skills, information, market access, rainfall, labor, land rights, organic fertilizer, sales channels, irrigation, as well as regional variations in foreign labor hiring, training, off-farm work, household head gender, age, and education level. Strategies to promote rubber farmers' diverse cropping systems should focus on training, education, financial support, incentives, and infrastructure development, particularly in regions with poor natural resources.

Summary: The research indicates that improper attribute selection based solely on sensory attributes is the main reason for the low effectiveness of the grading system for agricultural products. Consumers show a stronger preference for intrinsic quality attributes like crispness and sweetness, compared to external sensory attributes like color. An optimized grading system focusing on quality attributes leads to greater welfare improvement and benefits high-income consumers.

Summary: This paper uses agglomerative hierarchical cluster analysis to group 2778 farming-defined counties into six clusters, revealing farm patterns across the contiguous 48 states of the United States. The objective is to construct a policy-relevant farm clustering to characterize agricultural homogeneity in US farms' production potential. Six relatively homogeneous clusters are identified based on farm size, farm assets, farm labor, farm output, degree of mechanization, and government programs. This allows for analysis of policy changes on specific clusters and comparison of differential effects across clusters.

Summary: The aging of the agricultural labor force is an important issue in China's economic transformation. A study found that aging significantly affects apple production in Shaanxi Province, China, with apple growers in flatlands resorting to hired labor to replace family labor, while this substitution does not occur in mountainous areas.

Summary: This study reveals that the increasing trend of aggregate fertilizer use in Chinese agriculture can be explained by the shift in crop structure, which leads to an increase in the marginal utility of fertilizer at the extensive margin, offsetting the declining marginal utility at the intensive margin.
