THE HIGH COST OF EATING: CAUSES OF INTERNATIONAL DIFFERENCES IN CONSUMER FOOD PRICES

Prices of food vary greatly among the developed countries, and some countries' food prices have been consistently far above the OECD average. The main explanation for food price difference is the extent of protection of agricultural products at the farm level. A second important influence is the level of VAT on food. A third is deviations of aggregate country price levels from the levels that would be predicted from their per capita incomes, presumably because of omitted characteristics of the countries' economies, such as, possibly, inefficient or monopolistic service sectors. In addition, there are occasional episodes of high or low price levels due to temporary factors affecting exchange rates.
The degree of protection of agricultural products is treated both as an exogenous factor and as an endogenous one. In the latter case, it is explained by climatic conditions and, presumably, the political influence of the agricultural sector or a general desire to retain an agricultural sector despite poor growing conditions.     

Product price differences across countries: determinants and effects

A substantial part of international differences in prices of individual products, both goods and services, can be explained by differences in per capita income, wage compression, or low wage dispersion among low-wage workers, and exchange rate fluctuations. Higher per capita income is associated with higher prices and higher wage dispersion with lower prices. The effects of higher income and wage dispersion are moderated for the more tradable products. The effects of wage dispersion, on the other hand, are magnified for the more labor-intensive products, particularly low-skill services. The differences in prices across countries are reflected in differences in the composition of consumption. Countries in which prices of labor-intensive services are very high, such as the Nordic countries, consume much less of them. For some services, the shares of GDP consumed in high-price countries are less than 20% of the shares in low-price countries. Since these are services of very low tradability, the low consumption levels of these services imply low employment in them.
