Abstract
The topic of this research is the impact of the macroeconomic factors on food spending residents of St. Petersburg. The problem of the study is the ambiguity of the food sanctions impact on the consumer spending on food. The aim of the work are the trend analyze in the level of food spending in St. Petersburg since the first quarter of 2007 to the third quarter 2015, and the identifying of factors influencing these food waste. St. Petersburg was chosen because it is a city with a large population, which is located in the European part of Russia, it means that its inhabitants often bought European food products before the embargo. During the research the following tasks were performed: the description of the embargo’s chronology from 2014 to 2016; the definition of the basic mechanisms of behavior of contractors doing business in the food sector; Econometric analysis of the food spending dependency on the embargo, the GDP change, the cost of Brent crude oil and the Consumer Price Index. The following results were obtained: the availability of food embargo and the oil prices rising increase food waste. The GDP growth, in contrast, reduces the spending level. Influence of the Consumer Price Index reflects on food spending in different ways, depending on the product category. In addition, the forecast of expenditure on food in the III quarter of 2016 was created by the main research model. Thus, the study clearly showed that the embargo significantly increases consumer spending on food, despite the fact that its purpose is the import substitution. Actually, consumers finance import substitution in the agricultural sector.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
