Full textAbstract:
When adjusting product prices, marketers wish information concerning consumers' price perceptions. The present study aimed to develop an optimal pricing framework for food products by applying Weber's Law and Stevens' Power Law in psychophysics. The first phase attempted to measure the differential thresholds when magnitudes of prices were raised and lowered. The second phase was conducted to establish the psychophysical function representing perceived changes. Analysis showed consumers' differential thresholds were positively correlated with the initial price, consistent with Weber's Law. Further, participants' perceived change differed for increased and decreased prices. Products were perceived as cheaper only when medium-and low-priced products dropped dramatically in price. However, small reductions for the high-priced products were perceived as cheaper. Regardless of price changes, participants perceived products were more expensive when prices dropped by a small amount.

AbstractObjectivePeople on a limited budget want to know the ‘good price’ of foods. Here we report the methodology used to produce an educational tool designed to help recognize foods with good nutritional quality and price, and assess the validity and relevancy of the tool.DesignA ‘Good Price Booklet’ presenting a list of foods with good nutritional quality and price was constructed. The validity of the in-booklet prices was assessed by comparing them with prices actually paid by households from the Opticourses project. The relevancy of the booklet tool was assessed by semi-structured interviews with Opticourses participants.SettingSocio-economically disadvantaged neighbourhoods of Marseille, France.SubjectsNinety-one participants collected household food-purchase receipts over a 1-month period.ResultsBased on the French food database, foods with higher-than-median nutritional quality were identified. After grouping similar foods, 100 foods were selected and their corresponding in-booklet prices were derived based on the distribution of average national prices by food group. Household food purchases data revealed that of the 2386 purchases of foods listed in the booklet, 67·1 % were bought at prices lower than the in-booklet prices. Nineteen semi-structured interviews showed that participants understood the tool and most continued using it more than a month after the intervention.ConclusionsA method was developed to ease the identification of foods with good nutritional quality and price. The Good Price Booklet is an effective tool to help guide people shopping on a low budget.

Full textAbstract:
The Russian–Ukrainian conflict has led to the disruption of global supply chains, thus posing a threat to food security. The study aimed to assess the short-term impact of the conflict on food supply and global retail food prices resulting from the disruption of agri-food exports from Ukraine after the war outbreak. To assess the impact of the conflict on retail prices worldwide, the actual food price level during the conflict period was compared with the counterfactual values obtained from the forecasting models. The research points to a significant decline in Ukraine’s commodity exports at the beginning of the conflict leading to a supply gap for cereals in particular, affecting global access to staple foods. As a result, global food commodity prices rose sharply, however, the upsurge was short-lived, and as early as July 2022 price indices returned to their pre-war levels. On the other hand, in most regions worldwide the gradual and persistent increase in retail food prices was observed after the war outbreak. The study also found strong regional differentiation in the response of retail food prices to the conflict due to various specific factors that exacerbated or mitigated the impact of the war.

Abstract The price information system for Staple Food Prices is very helpful to the public by providing information on raw food prices for the Bandar Lampung markets. This information system allows the public to determine the price of food raw materials according to grouping: by product, by market and prices at a specific time. Investigation of information systems using data matrices and objects as alternative databases using JSON (JavaScript Object Notation), one of which applies information technology in the use of information systems with matrices and objects as others alternative databases. The results obtained are the monitoring of prices for the basic needs of the population to support the information system on the prices of basic foods. In general terms, how to monitor the price of community staples in support of the basic food price information system to capture the prices of basic community needs in each market. It is possible to use a database system with JSON in addition to an existing database, for example a relational database.

Objective: To examine the effects of increasing minimum wage on supermarket food prices in Seattle over 2 years of policy implementation, overall and differentially across food quality metrics. Methods: Prices for the UW Center for Public Health Nutrition (CPHN) market basket of 106 foods were obtained for 6 large supermarket chain stores in Seattle (“intervention”) and for the same chain stores in King County (“control”) at four time points: 1-month pre- (March 2015), 1-month post- (May 2015), 1-year post- (May 2016), and 2-years post-policy implementation (May 2017). Prices for all food items were standardized and converted to price per 100 kcal. Food quality metrics were used to explore potential differential price increases by (a) food groups, as defined by US Department of Agriculture; (b) NOVA food processing categories, and (c) nutrient density quartiles, based on the Nutrient Rich Foods Index 9.3. Separate difference-in-differences linear regression models with robust standard errors, examined price differences per 100 kcal overall, clustered by store chain, and stratified by each food quality metric. Results: There were no overall market basket price changes attributable to Seattle’s minimum wage policy. Moreover, no minimum wage effect was detected by USDA food group, food processing, or nutrient density categories. Conclusions: Local area supermarket food prices were not impacted by Seattle’s minimum wage policy 2 years into policy implementation and after the first increase to $15/h overall or by sub-classification. Low-income workers may be able to afford higher quality diets if wages increase yet supermarket prices stay the same.

PurposeEmpirical studies have documented the linkage between exchange rate movement and food prices. However, the purpose of this study is to investigate the degree and direction of returns and volatility spillover transmission between exchange rate and domestic food prices in Nigeria.Design/methodology/approachThe study uses weekly data from January 2010 to January 2019. Also, the study adopts the improved Diebold and Yilmaz (2012) approach to evaluate the return and volatility spillover between food price and naira to dollar exchange rate. The study also account for 2016 exchange rate crash in the interconnectedness between food prices and naira to dollar exchange rate.FindingsThe paper finds evidence of directional interdependence among the considered food prices and exchange rate based on the obtained spillover indexes. In addition, exchange rate returns and volatility transmission to food prices is more than it receives, particularly after the exchange rate crash.Research limitations/implicationsThe high consumption of staple foods requires policies on price stabilisation such as massive investment in local production and reduction in import dependence, in order to cushion the effects of exchange rate depreciation on domestic prices of food.Originality/valueThis study is the first empirical study to investigate the interconnectedness between exchange rate and domestic food prices for a food import–dependent developing country using the Diebold and Yilmaz approach.

Full textAbstract:
During the last decade (2000–2010), we have witnessed an unprecedented rise in food prices, especially from the world and European market viewpoint. The article aims to analyze the development of prices in the food market in the Czech Republic and to identify the influence of global and European prices development on domestic food price development and price development of selected food products. The article focuses primarily on the sensitivity of Czech food price development and especially on sensitivity of the selected commodity aggregations price development on the global and European market price growth. Furthermore, it is analyzed the impact of changes in value added tax rate from 10% to 14% on food prices in general and then on the prices of selected food products in retails network. The results of the analysis are following. The Czech food market reacts sensitively to changes in food prices on the global market as well as on the EU market but the EU price development is determining for the CR. In terms of price response to change in the VAT rate, it appears that the growth rate is not absorbed on the production side but it is largely transferred to consumer prices. The selected food sample also showed high responsiveness in the development of prices to changes in the EU market prices but there are certain variations given by specifics of the Czech market.

Full textAbstract:
This article investigates the extent to which national brand and private label (store brand) prices behave differently as food price inflation changes. Empirical tests using a range of indices support the hypotheses that rising commodity and fuel prices lead to relatively larger surges in private label prices. When food prices are rising or high, the average price difference between national brands and private labels shrinks. The findings have implications for understanding the welfare effects of private labels. Moreover, they suggest that food price inflation is stronger for low-income households as food prices rise.

AbstractObjectiveTo examine the impacts of Seattle’s minimum wage ordinance on food prices by food processing category.DesignSupermarket food prices were collected for 106 items using a University of Washington Center for Public Health Nutrition market basket at affected and unaffected supermarket chain stores at three times: March 2015 (1-month pre-policy enactment), May 2015 (1-month post-policy enactment) and May 2016 (1-year post-policy enactment). Food items were categorized into four food processing groups, from minimally to ultra-processed. Data were analysed across time using a multilevel, linear difference-in-differences model at the store and price level stratified by level of food processing.SettingSix large supermarket chain stores located in Seattle (‘intervention’) affected by the policy and six same-chain but unaffected stores in King County (‘control’), Washington, USA.SubjectsOne hundred and six food and beverage items.ResultsThe largest change in average price by food item was +$US 0·53 for ‘processed foods’ in King County between 1-month post-policy and 1-year post-policy enactment (P < 0·01). The smallest change was $US 0·00 for ‘unprocessed or minimally processed foods’ in Seattle between 1-month post-policy and 1-year post-policy enactment (P = 0·94). No significant changes in averaged chain prices were observed across food processing level strata in Seattle v. King County stores at 1-month or 1-year post-policy enactment.ConclusionsSupermarket food prices do not appear to be differentially impacted by Seattle’s minimum wage ordinance by level of the food’s processing. These results suggest that the early implementation of a city-level minimum wage policy does not alter supermarket food prices by level of food processing.

Abstract This paper analyzes the relationship between food and oil prices in Nigeria before and during the COVID-19 pandemic, using monthly data from January 2018 to December 2021. The ARDL and NARDL models are applied to estimate the symmetry and asymmetric relationship that exists in food price behavior. The NARDL confirms the presence of asymmetries, and the bound test affirms the co-integration and long-run relationship among the variables. In the long run, there is a significant positive relation between oil price increases and food prices, but the long-run impact of oil price reductions on food prices is not significant. In the short run, only increases in oil prices exert a significant influence on food prices, while decreases in oil prices do not. Furthermore, the COVID-19 period exerts a positive and significant impact on food prices, while COVID-19 cases do not influence food prices in Nigeria.
