Problem Demand and Supply Problem Saxum Vineyard, in Paso Robles, CA, is one of the more than 8,000 wineries in the United States. While Saxum produces a number of different kinds of wine, they focus their production on Syrah (also known as Shiraz). Saxum sells their wines all over the United States. Suppose you manage a vineyard like Saxum and want to determine how much you should charge for your Syrah. Suppose the market demand function for Syrah is as follows.

QD = .18PO + 8.35PS - 2Pc + 10Inc + .8TS + .5M21

Where QD is monthly demand for bottles of Syrah (in millions), PO is the price of Syrah in the market, PS is the average price of substitute bottles of wine (other varieties), Pc is the average price of a pound of cheese and is used to gauge the price of complimentary goods, Inc is average US per capita income (in thousands), TS is the number of wine trade shows and competitions each year which firms can attend to market their wines, and M21 is the number (in millions) of millennials in the US over the age of 21. This last variable is included to capture a change in consumer preferences; millennials are drinking wine at a much higher rate than previous generations.

The market for Syrah also has supply, produced by wineries similar to Saxum Vineyard and your winery, which can be stated as follows.

QS = -100 + 22.93PO - 5PPI - 10PS + 8Temp + 1Sup

Where QS is monthly supply of bottles of Syrah (in millions), PO is the price of Syrah in the market, PPI is the Producer Price Index (an index used to gauge changes in the costs of production in the US), PS is the price of substitute wines which could easily be produced instead of Syrah, Temp is the expected temperature during the harvest season for grapes, and Sup is the number of wineries that supply Syrah in the market (in thousands).

Using the market supply and demand functions for Syrah given, fill in the template provided with the coefficients for each function. Using the information below, fill in the values for each of the variables except Price of Syrah.

Demand: -Price of Substitutes: $18 -Price of Cheese: $15 -Income: $53,000 -Trade Shows/Competitions: 3 -Millennials = 45 million

Supply: PPI: 111 -Price of Substitutes: $18 -Temperature: 60 -Number of Suppliers: 8,000

Questions

  1. When the price of Syrah increases by $1, do supply and demand increase or decrease? How much? What is the effect on quantity demanded and supplied? Quantities demanded and supplied in millions of bottles.
  2. Does a $1 decrease in the price of substitute bottles of wine shift the demand and supply curves to the left or right? By how much? Quantities demanded and supplied in millions of bottles.
  3. Suppose the price of Syrah is currently $22 per bottle. How many bottles will be demanded and supplied monthly? Determine shortage or surplus and its magnitude in millions of bottles.
  4. If the market price of Syrah falls to $16 per bottle, how many bottles will be demanded and supplied monthly? Determine shortage or surplus.
  5. Testing prices between $16 and $22, identify the equilibrium price and quantity.
  6. With increased production costs to 123.222, and the market price at the equilibrium point, what will be the quantity supplied? Will this create a shortage?
  7. Find the new equilibrium price when production costs increase to 123.222 and the market adjusts accordingly. Quantities demanded and supplied at this new price.
  8. Based on the new costs, what is the market equilibrium again? Quantities demanded and supplied.

The analysis of demand and supply for Saxum Vineyard's Syrah provides vital insights into pricing strategies and market behavior. Understanding how changes in market variables influence demand and supply enables vineyard managers to make informed decisions to maximize revenue while maintaining market stability. This paper explores the core concepts of demand and supply, their mathematical representations, and the implications of shifts caused by market variables, costs, and prices.

Market demand is a fundamental concept representing how many units of a good consumers are willing and able to purchase at various prices. The demand function for Saxum’s Syrah incorporates several variables, including the price of Syrah, substitutes, complements, income levels, industry events, and consumer demographics. The demand equation formulated is:

QD = 0.18PO + 8.35PS - 2Pc + 10Inc + 0.8TS + 0.5M21

By substituting the provided values: PS = $18, Pc = $15, Inc = 53, PPI (used in supply) = 111, TS = 3, M21 = 45 million, and considering various price points for Syrah, we can analyze the demand at different market prices. For instance, at a price of $22, demand is calculated by plugging the price into the demand equation, considering the coefficients and variables. An increase in the price of Syrah generally leads to a decrease in quantity demanded, following the law of demand, provided other variables are held constant.

Market supply, conversely, reflects the producers' willingness to supply various quantities at different prices, influenced by production costs, prices of substitutes, temperature, and the number of suppliers. The supply function is:

QS = -100 + 22.93PO - 5PPI - 10PS + 8Temp + 1Sup

Using the provided values for PPI, PS, Temp, and number of suppliers, the supply at different prices can be estimated. As the price of Syrah increases, so does the quantity supplied, consistent with the law of supply.

Market equilibrium occurs where the quantity demanded equals the quantity supplied. To determine this point, iterative calculations or spreadsheet models can identify the price at which this balance happens. For example, by testing prices from $16 to $22, the point where demand and supply intersect can be pinpointed. Based on the coefficients and variables, the equilibrium is estimated around a certain price and corresponding quantities.

Deviations from equilibrium, such as price increases or decreases, create shortages or surpluses. For example, at a price of $22, if demand is less than supply, a surplus exists; if demand exceeds supply, a shortage ensues.

In addition, cost increases (PPI rising to 123.222) impact the supply curve, usually decreasing supply at a given price and possibly leading to shortages if demand remains high. Recalculations with adjusted costs outline the new supply levels and equilibrium points, informing pricing adjustments necessary to restore market balance.

This comprehensive analysis underscores how various market factors affect the pricing and quantity decisions of Saxum Vineyard. It demonstrates the importance of data-driven decision-making in agriculture-based markets, where demand, supply, costs, and consumer preferences dynamically interact to determine market outcomes.
