Summary: To address fluctuating hog prices and maintain market stability, the Chinese government has implemented various control policies. The study found that while the policy design is reasonable, there are issues such as a singular policy subject, neglect of long-term structural adjustments, inadequate support, and lack of consideration for social equity.

Summary: To achieve the goal of zero hunger in sustainable development, it is crucial to enhance the resilience of food systems to various risk shocks. This study analyzed the impact of China's lockdown policy and food security emergency policy during the COVID-19 pandemic on food prices, highlighting the role of policy intervention in strengthening the food system's resilience. The implementation of transport policy and joint supply emergency policy in the main producing and consuming areas played a significant and positive role in stabilizing food prices.

Summary: The study evaluated scientific publications related to food security, price volatility, and price transmission, finding a rising trend in research associated with food security. The analysis results suggest that the shift in scientific research trends associated with food security analysis is linked with health and food nutrition status.

Summary: There is existing literature on how food companies, including unhealthy food commodity industries, influence policy through both direct and indirect approaches. This includes lobbying, funding research, funding community groups, and supporting food charities. The connections between food companies and food charities have raised concerns about the potential compromise of public health policy and the influence on wider food policies.

Summary: The fluctuation of vegetable prices in recent years highlights the importance of identifying contributing factors and developing effective policies. This paper uses a structural model to decompose price variance and conducts a numerical simulation to generalize the results, focusing on the Korean vegetable market. The study finds that variability of domestic production is the primary factor influencing price fluctuations, while demand, import, and export have limited impact except for dried red pepper and onion.

Summary: The study found that the combination of subsidies for healthy products and taxes on unhealthy products in nudging and price salience condition was most effective, particularly in increasing purchases of dairy and grains. Additionally, within-food group substitution patterns towards healthier products were observed in grains and dairy categories.

Summary: Greenhouse gas emissions related to UK food consumption have significantly decreased over the past 20 years, primarily driven by reductions in household food budgets and evolving food preferences. While relative price dynamics and demographic trends have a smaller impact, policy interventions targeting consumer preferences could be an effective tool in further reducing food-related emissions.

Summary: This article provides evidence that food aid increases the adoption of climate adaptive agricultural practices in smallholder households in Ethiopia and Malawi. However, for less risky and less resource-intensive practices, there is a substitution effect triggered by food aid.

Summary: The issue of welfare is a significant concern in Ethiopia due to fragile agricultural productivity, exchange rate devaluation, and high food prices. Improving agricultural land productivity positively affects welfare, while labor productivity in agriculture has a negative impact. Additionally, exchange rate depreciation and food price increases threaten welfare by eroding purchasing power and exacerbating supply-demand divergence in the economy.

Summary: Food price volatility poses a major threat to welfare, economic prosperity, and political stability. In addition to the monetary authority, food price stabilization policies using fiscal instruments are also important for controlling inflation. This study develops a Bayesian DSGE model tailored to India and incorporates both monetary and fiscal policies, specifically focusing on food demand and supply subsidies. The findings show that the absence of food subsidies would lead to a 21% increase in CPI and interest rate volatility following a global food price shock. Ignoring this effect would result in an overestimation of the effectiveness of inflation targeting by the central bank. The subsidy policy has significant heterogeneous distributional welfare effects, with farmers benefiting from all subsidies and the inclusion of urban households in the demand subsidy program being necessary to offset the welfare cost of supply subsidies.

Summary: We conducted a survey on caterers with and without past hygiene violations to investigate their staffing, food safety practices, and correlations with microbial counts in food and the processing environment. The study found that past infringements did not have a negative impact on the current execution of food safety measures or the microbial quality of food. Instead of imposing stricter regulations on errant operators, alternative efforts to enhance food safety and their policy implications are discussed.

Summary: The research found that the implementation of the cotton target price subsidy policy stimulated cotton production, but there were issues such as increased production and decreased yield per unit area. Additionally, the policy mainly expands cotton planting scale by reducing the planting area of competitive crops.

Summary: Current supermarket price promotions can encourage unhealthy diets, leading governments to endorse restrictions on price promotions for unhealthy food and beverages. However, little is known about the industry response to such policies. This study aimed to understand how potential government policies targeting food and beverage price promotions in supermarkets are perceived by food industry stakeholders in Australia. The study found that industry opposition to price promotion policy could be driven by fear of losing competitive advantage, potential financial loss, skepticism of health impacts, and increased cost to consumers. Forces that could drive policy implementation for public health benefits included mandatory regulation, compliance monitoring, support for promoting healthy products, consumer education, and retailer support. These forces and their interactions should be considered when changing the healthiness of supermarket price promotions for food and beverages.

Summary: Exploring the hedging ability of precious metals through a novel perspective is crucial for better investment. This investigation applies the wavelet technique to study the complicated correlation between global economic policy uncertainty (GEPU) and the prices of precious metals. The empirical outcomes suggest that precious metals could hedge against global economic policy uncertainty, supported by the inter-temporal capital asset pricing model (ICAPM). In the context of increasing instability of global economic policies, these conclusions offer significant lessons to both investors and governments.

Summary: This paper examines the trends in agricultural raw materials prices compared to food prices in Poland before and after its accession to the European Union. The study finds that joining the EU improved the situation for farmers in the agricultural markets, with a reversal of downward price trends in agricultural raw materials and their stabilization. The level of price transmission varies depending on the product group.
