Summary: | Dairy production often occurs in distorted, highly protected environments, which
affect both the price and quality of the end product. Current Canadian regulations serve to
protect the local dairy industry with production quotas and high import tariffs. By raising the
price of milk, these regulations may induce Canadian cheese manufacturers to find ways to
substitute away from Canadian milk inputs to lower costs and maximize profit. Given that
some alternative ingredients can be imported without tariffs, it is natural to examine the link
between protective policies for Canadian milk and the quality of processed milk products
such as cheese.
Along with the regulations, other changes have occurred in the Canadian cheese
processing industry. The structure of the Canadian dairy processing industry has undergone a
significant rationalization process in the last decade. The shift into fewer and larger plants has
been necessary to achieve the efficiency level and economies of scale to remain competitive.
Over the past decade, technological change has induced processors to substitute alternative
inputs for the traditional ingredients, which in turn has affected the quality of final products
such as cheese.
There has been a great deal of research on the price and efficiency effects of Canada's
supply management system for dairy production, but little (or no) work has been done on the
effects of supply management on the quality of processed milk products at the consumer level.
I develop a theoretical and empirical model to examine the effect of Canadian regulations,
technological change and industry consolidation on cheese quality. The analysis helps explain current quality trends in the Canadian cheese and dairy industry, as well as the social cost of
Canadian supply management in milk products.
This thesis uses theoretical and empirical analysis to examine the effects of supply
management on quality in the dairy industry, thereby filling a gap in the literature.
Specifically, for the theoretical model I examine the effect of supply management on cheese
quality, quantity produced and number of firms in the industry using some comparative statics
analysis. For the empirical model, I use the derived demand equation for casein as a function
of the reduced form demand for the outputs (cheddar, specialty cheese, yogurt and ice cream),
the marginal costs (milk price, wage and metal) and the number of plants to determine the
effect of high levels of protection on product quality.
Most of the empirical results match the theoretical ones. In both models, evidence
suggests that supply management negatively affects cheese quality. In the theoretical model,
supply management, by increasing marginal costs, increases the quantity of extended cheese
produced. In the empirical model, the quantity of casein imports increases in response to an
increase in the price of milk. The results of the empirical model suggest that approximately
9.8% of specialty cheese is produced using casein. Furthermore, I estimate the amount of milk
displaced by casein if milk price increases one dollar, 722.65 hi of milk per month; and the
implied spillover effect on Canadian dairy farmers, which, on average, decreases their rents
by 33,033 dollars per month.
