Changing household characteristics and the away-from-home food market: a censored equation system approach

The American consumer is obtaining more-and-more of his or her food at a restaurant, and that worries some people concerned with the Nation’s dietary health. To date, much of this concern seems to be directed at the fast food segment of the restaurant industry. This paper asks whether targeting one segment of the industry, such as fast food restaurants, is justified, or whether a more balanced view of eating away from home is required. To answer this question, we look to the future and ask whether Americans can be expected to purchase increasingly more fast food or more-and-more of the foods typically associated with full-service dining. One view is that sales at full-service restaurants will now grow relatively faster than sales of fast food. The argument supporting this position rests on rising incomes, the aging of the population, smaller household sizes, and other changes taking place in the population. Using a new full-information maximum likelihood procedure for estimating a system of censored expenditure equations, we find evidence to support this argument.

Is rationing socialist?: Cuba's food distribution system

Cuba, an economically underdeveloped country, has achieved a goal that even most developed countries find elusive: it has eliminated hunger. A 1982 report prepared for the Joint Economic Committee of the US Congress acknowledged that Cuba has ‘eliminated almost all malnutrition, particularly among small children.’¹ This article looks at how Cuba has managed to feed its people. It also questions whether the system created 25 years ago to ensure just distribution, ie rationing, today stands as an obstacle to the further development of Cuba's food system.     

Identify Customer Involvement During Organic Food Purchase Through FCB Grid

The study measures the level of customer involvement related to Organic Food (OF) purchase through FCB Grid. A conceptual model was developed to identify the location of OF in FCB Grid by testing the sequencing of Knowledge, Attitude and Purchase Behavior effects. Two scales were adopted from a study by Ghosh et al. (2016 Ghosh, S., Datta, B., &; Barai, P. (2016). Modeling and promoting organic food purchase. Journal of Food Products Marketing, 22, 623–642. doi:10.1080/10454446.2016.1141138[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) to measure Knowledge and Attitude pertaining to organic food. Similar such scale with minor moderation was formed for Purchase behavior. 868 responses were analyzed through Structural Equation Model, which indicates that OF falls on the first quadrant of FCB grid and is a high involvement product. This implies Knowledge drives Attitude and Attitude drives Purchase Behavior and demands informative strategy where economic considerations prevail prior to purchase. Organic food production is a sustainable process and positively impacts the livelihood of marginal farmers and will improve the quality of the soil and health of the consumers.     

The quantity and variety of households’ meat purchases: A censored demand system approach

This study investigates the demand for 10 disaggregated meat products by U.S. households. A censored demand system which imposes budget constraints in both observed and latent shares is estimated along with a detailed explanation of the estimation procedure. Additional details about the methodology not provided in previous studies should help researchers to empirically apply the model. An innovation of the study is to introduce the censored demand system model for studying the variety of a household's food purchases. Most households buy between seven and eight different products and hardly change the variety of their purchases with changes in meat expenditure.     

Big social data and customer decision making in vegetarian restaurants: A combined machine learning method

Customers increasingly use various social media to share their opinion about restaurants service quality. Big data collected from social media provides a data platform to improve the service quality of restaurants through customers' online reviews, where online reviews are a trustworthy and reliable source that helps consumers to evaluate food quality. Developing methods for effective evaluation of customer-generated reviews of restaurant services is important. This study develops a new method through effective learning techniques for customer segmentation and their preferences prediction in vegetarian friendly restaurants. The method is developed through text mining (Latent Dirichlet Allocation), cluster analysis (Self Organizing Map) and predictive learning technique (Classification and Regression Trees) to reveal the customer’ satisfaction levels from the service quality in vegetarian friendly restaurants. Based on the obtained results of our experiments on the data vegetarian friendly restaurants in Bangkok, the models constructed by Classification and Regression Trees were able to give an accurate prediction of customers' preferences on the basis of restaurants' quality factors. The results showed that customers’ online reviews analysis can be an effective way for customers segmentation to predict their preferences and help the restaurant managers to set priority instructions for service quality improvements.     

Examining sustainability performance in the supply chain: The case of the Greek dairy sector

This paper evaluates the sustainability performance of the Greek dairy chain and the performance of its individual members by using key indicators in relation to efficiency, flexibility, responsiveness and product quality. We assessed the importance of these indicators based on the relevant perceptions of key members of this chain. A structured questionnaire was developed where nineteen sustainability-related issues were examined. Two hundred and fifty three members of the Greek dairy supply chain responded including breeders, manufacturers, wholesalers, retailers and catering companies. Our findings illustrate the immediate need for improvement in many key sustainability performance indicators. They also show the critical role of large dairy manufacturers who are the “sustainability performance champions” in this chain and are the driving force for the implementation of many sustainability initiatives.     

Inter‐ and intra‐seasonal crop acreage response to international food prices and implications of volatility

Understanding how producers make decisions to allot acreage among crops and how decisions about land use are affected by changes in prices and their volatility is fundamental for predicting the supply of staple crops and, hence, assessing the global food supply situation. This study makes estimations of monthly (i.e., seasonal) versus annual global acreage response models for the world's principal staple food crops: wheat, corn, soybeans, and rice. Primary emphasis is given to the magnitude and speed of the allocation process. Estimation of intra‐annual acreage elasticity is crucial for expected food supply and for input demand, especially in the light of the recent short‐term volatility in food prices. The econometric results indicate that global crop acreage responds to crop prices and price risks, input costs as well as a time trend. Depending on respective crop, short‐run elasticities are about 0.05 to 0.40; price volatility tends to reduce acreage for some of the crops; comparison of the annual and the monthly acreage response elasticities suggests that acreage adjusts seasonally around the globe to new information and expectations. Given the seasonality of agriculture, time is of an essence for acreage response. The analysis indicates that acreage allocation is more sensitive to prices in the northern hemisphere spring than in winter and the response varies across months.     

A new market for an old food: the U.S. demand for olive oil

While U.S. consumption of olive oil has tripled over the past two decades, nearly all olive oil continues to be imported. Estimation of a demand system using monthly import data reveals that the income elasticity for virgin oils sourced from EU is above one, but demand for nonvirgin oils is income‐inelastic. The demand for olive oil as a single product is price‐inelastic. Differentiated by product characteristic and origin, olive oils are highly substitutable with each other but not with other vegetable oils. News about the health and culinary benefits of olive oil and the spread of Mediterranean diet contribute significantly to the rising demand.     

食品安全信息披露的博弈分析

食品质量安全信息披露不足,导致消费者难以分辨食品的安全性,不能对市场中的食品产生信任。本文建立消费者与生产者的信号博弈模型并找寻了动态均衡路径,分析认为:食品生产企业要获得消费者信任并实现与低质量企业完全分离,必须披露更多的质量安全信息,同时高质量企业披露安全信息对企业有利。通过比较国外为获得消费者信任而加强食品安全信息披露的情况,指出现阶段国内食品安全信息披露的不足,提出引导高质量企业进行更多信息披露、加强信息沟通交流和落实信息披露机制的建议。
