Factors Influencing Price of Agricultural Products and Stability Countermeasures

Factors leading to rise of prices of agricultural products mainly include tension of supply-demand relationship,promotion of production cost and circulation cost,and speculation of Refugee Capital(Hot Money).Factors leading to low price and difficult sales of agricultural products mainly include asymmetry of supply-demand information,lack of risk management tools for prices of agricultural products and decentralized and small-scaled operation of farmers.On the basis of these factors,this paper presents following countermeasures and suggestions for stabilizing prices of agricultural products:firstly,building long-effect mechanism for production and sales of agricultural products;secondly,expand the production and increase supply of agricultural products;thirdly,control the rising range of production cost for agricultural products;fourthly,enhance organization level of farmers;fifthly,promote innovation and development of risk management tools for prices of agricultural products.

Empirical Study on the Impact of Rural Labor Force Flow on the Price of Agricultural Products——A Method Based on VEC Model

Based on the research introduction of domestic and foreign scholars,dynamic equilibrium between the rural labor force flow and the price of agricultural product is analyzed by VEC model,according to the data of the rural labor force flow and the price of agricultural products in the years 1990-2007.Chows breakpoint test is used to measure the stage characteristics of the impact of rural labor force flow on the price of agricultural product.Result shows that there is a long-term and stationary relationship between the flow quantity of rural labor force and the price of agricultural product.Rural labor force flow,as an exogenous force,affects the agricultural production,and further influences the price fluctuation of agricultural products.Impact of rural labor force flow on the price of agricultural product is from weak to strong,then grows gradually weaker,and reaches its peak value at the year 1998.With the development of rural society and economy and the market process,rural labor force flow endogenously affects the price of agricultural product,which has periodic characteristics.In order to achieve a dual stabilization of the rural labor force flow and the price of agricultural products,the following countermeasures are put forward:vigorously developing vocational education,increasing the support for agricultural production,and making active employment measures.

Feasibility Analysis of Agricultural Product Price Index Insurance Based on Pilot Cases

Agricultural product price index insurance is a kind of index insurance. It avoids defects of traditional agricultural insurance,such as moral hazards,adverse selection,and high management cost. On the basis of studying agricultural product price index insurance of all areas of China,this paper analyzed characteristics of agricultural product price index insurance from object selection,product object,premium design,and policy support,and discussed feasibility of extending agricultural product price index insurance in an all-round way.

Impact and Policy Implications of Swine Epidemic on Price Fluctuation of Livestock Products in China

The drastic price fluctuation of livestock products caused by frequent swine epidemics has seriously affected the stable and healthy development of the livestock product market.It is important to develop strategies for the stability and development of livestock product market by understanding the impact of swine epidemic on the price of livestock products.Therefore,we systematically analyzed the impact of the swine epidemic on the price of livestock products in China based on monthly data from February 2009 to July 2020 using the factor augmented vector autoregression(FAVAR)model.The results showed that:(i)During the swine epidemic,the price of pork first showed a negative response and then a positive response,while the price of other livestock products showed positive response overall.(ii)The price of pork was the most affected by the swine epidemic,followed by price of chicken.Price fluctuation of beef and mutton was similar,and the price response of eggs and fresh milk was relatively smaller.Based on these results,we put forward policy suggestions for stabilizing the price of livestock products in China during swine epidemic from the aspects of improving the defense system and guiding consumption scientifically.

Inflation, Deflation and Normal Price Adjustment

This paper thinks that the price of a commodity depends on both the value of the commodity and that of the currency. The change in either value will cause the change of the price of the commodity. Only the price rising caused by the decreasing of the currency value can be called inflation, and the price rising led by the increasing of the value of the merchandise can not be called inflation. Therefore, it is not proper, as defined by the modem economics, to think that any price increasing should be in general called inflation.

DISRUPTION MANAGEMENT FOR SUPPLY CHAIN COORDINATION WITH EXPONENTIAL DEMAND FUNCTION

The coordination problem of a supply chain comprising one supplier and one retailer under market demand disruption is studied in this article. A novel exponential demand function is adopted, and the penalty cost is introduced explicitly to capture the deviation production cost caused by the market demand disruption. The optimal strategies are obtained for different disruption scale under the centralized mode. For the decentralized mode, it is proved that the supply chain can be fully coordinated by adjusting the price discount policy appropriately when disruption occurs. Furthermore, the authors point out that similar results can be established for more general demand functions that represent different market circumstances if certain assumptions are satisfied.

Analysis on the Effect of Asymmetric Information on Product Supply Chain and Pricing

Along with the vigorous development of the markel economy, the transactions in the market are also increasingly frequent. In all kinds of market transactions, there are more or less inIbrmation asynunetry phenomena. Asynmaetric information makes supply chain unable to give a real reaction to the relationship between market supply and demand, and the personnel in the channels of supply chain are unable to make the optimal pricing, so that the overall profits are affected. Therefore, asymmetric information should be controlled within the normal range, for the purpose of ensuring the normal operation and healthy development of the market transactions.

Production quality and pricing strategy for substitutable products under comparison effects

Comparison effects have been studied extensively in many fields.In particular,existing operations management articles have discussed the impact of comparison effects on enterprises'production and pricing decisions.Research has also shown that consumers'purchasing decisions are primarily determined by three factors:product quality,selling price,and comparison effects.The current study introduces the concepts of social and temporal comparison effects to examine how comparison effects influence a monopolist's production quality and pricing strategy for substitutable products.Results reveal the following:(1)Setting different prices for even two types of substitutable products with negligible quality differences can divide customers into three groups under the influence of social comparison effects in a single-stage model.(2)The monopolist should avoid using a price discrimination strategy in which products with a short market life cycle have the same quality but different prices.(3)When the market life cycle of products is sufficiently long in the single-product market and the market with two substitutable products,the monopolist's optimal choice in the second stage is to keep production quality constant and increase the selling price.Consequently,the number of buyers does not decrease because of temporal comparison effects.Therefore,the firm increases its revenue.(4)For the market with two substitutable products with quality differences,one approximate optimal strategy for the enterprise in the second stage is to keep the selling price constant with the assumption that product quality cannot be adjusted after the first period.At this point,the consumption situation in the market is the same as that in the first stage.Therefore,when no external constraints exist,the monopolist firm can obtain more benefits in the second stage than in the first stage by exploiting the temporal comparison effects of consumers in the second stage.(5)When consumer identity information can be confirmed in the market,social comparison effects,similar to temporal comparison effects,could help the enterprise increase its price and profit while maintaining product quality.These social and temporal comparison effects constrain consumers.Thus,the number of people who continueto buyproducts does not decrease.

Corrosion is a damage or a change of state of materials caused by interactions between materials and environmental factors, which, together with fracture and wear, have become the three major reasons for the failure of structural materials. Normally, corrosion takes place or originates on or from the surface of materials. Therefore, surface technology （such as coating） is one of the important measures to mitigate and control the process of corrosion.

CAPACITY COMMITMENT AND PRICING FOR SUBSTITUTABLE PRODUCTS UNDER COMPETITION

Capacity acquisition and pricing decisions are a company＇s long-term strategic decisions. However, demand uncertainty and substitutability of multiple products cause the difficulty to solve capacity and pricing decision problems. In this paper, we address a multiple product pricing and multiple resource capacity acquisition problem with demand.uncertainties and competition. The company needs to determine capacity commitment for each resource and product prices before demands are realized so that the total profit is maximized. If the demand exceeds the committed capacity, extra amounts can be purchased from the spot market. Variable unit production costs, capacity acquisition and maintenance costs are considered. We first analyze a single company basic problem and find the optimal solutions on prices and capacity. Based on the single company model, we address the two-product, two-firm capacity commitment and pricing problem considering across product and across company price competition factors. The existence and uniqueness of equilibrium on price and capacity commitment are proved, and then we extended the results to the multiple product, multiple company case.
