Volkswagen in Russia In the mid-2000s, Volkswagen announced that it would invest directly in automobile production in Russia. The decision to invest was driven by a number of factors. Russia’s economy was growing rapidly at the time and living standards were rising, while the level of car ownership per capita was still low by European standards. This suggested that demand for cars would grow rapidly going forward. Indeed, forecasts predicted that by 2020, Russia would surpass Germany to become the largest car market in Europe. Moreover, Volkswagen’s global rivals, including most notably Toyota, General Motors, and Ford, were also investing in production facilities in Russia, so Volkswagen felt that it had to make direct investments in order to avoid being preempted by its rivals. The Russian government also createdPage 238 incentives for carmakers to invest directly in Russian production facilities, allowing them to avoid import tariffs and a punitive tax on imports of parts if they produced at least 25,000 cars in the country. In 2011, the government announced that it would keep tariffs on imported components at 0.3 percent if a foreign automaker built at least 300,000 in the country by 2020 and produced 60 percent of the value of the car locally. Spurred on by such incentives, in 2007 Volkswagen opened a plant in Kaluga, 160 miles southwest of Moscow, to build some of its VW and Skoda car brands. The plant was projected to have a peak capacity of 150,000 units a year and employ 3,000 people. Initially all vehicles at the plant were assembled from semi-knocked-down kits imported from Germany. In October 2009, however, the plant launched full-scale production, including welding and painting of vehicles. In October 2011, Volkswagen announced that, together with a local partner, GAZ Group, it would open a second plant near St. Petersburg, as it strove to reach the 300,000 units of local production by 2020. In 2013, Volkswagen made an additional investment in Kaluga when it pledged 300 million euros to build an engine plant near to its assembly operation. The engine plant opened in September 2015. All told, by this point Volkswagen had invested over $1 billion in production in Russia. General Motors and Toyota had also announced investments of over $1 billion to boost Russian production up to 300,000 units by 2020, and Fiat had indicated that it would make investments to bring its Russian production up to 300,000 as well. In total, foreign carmakers had invested over $5 billion in Russian assembly operations by 2014. Meanwhile, analysts continued to predict that the Russian car market would grow at a healthy pace and exceed that of Germany by 2020. In 2014, however, the market took a sharp turn for the worse. Russia is a major oil producer. Since the mid-2000s, much of the country’s economic growth had been powered by high oil prices. In the second half of 2014, however, global oil prices started to fall rapidly as increased production in America and weak demand in China conspired to create a global glut of oil. By early 2016, oil prices had fallen 80 percent from their peak. To make matters worse, following hard on the heals of its hostile takeover of the Crimea region from Ukraine, Russia had become embroiled in a smoldering civil war in eastern Ukraine. Western nations responded to what they perceived as Russian aggression by imposing sanctions on Russia. Hit by these twin blows, the Russian economy weakened significantly in 2014 and 2015, and the ruble declined precipitously, losing 50 percent of its value against the U.S. dollar. Suddenly the bright hopes that foreign automakers had for the Russian market seemed to be tarnished. Faced with falling demand, Volkswagen cut production at its Kaluga plant to 120,000 vehicles from a planned 150,000. With the new engine plant scheduled to come on line and no resolution to Russia’s economic crisis insight, Volkswagen’s excess capacity problem may get worse. Looking forward, Volkswagen has to decide whether to keep investing in Russia in order to hit the magic 300,000 local output figure by 2020 or to pull back from a market whose future suddenly looks highly uncertain. At this point, it looks as if Volkswagen is staying the course. In late 2015, a Volkswagen board member noted that “We need to continue to strengthen our partnership (in Russia) despite the current situation”.* Sources: Sarah Sloat, “Volkswagen to Halt Production at Russian Plant for 10 Days,” The Wall Street Journal, September 7, 2014; Clare Nuttall, “Foreign Car Firms Invest Heavily in Russia,” The Telegraph, April 28, 2011; Staff reporter, “Volkswagen Russia Shows the Way,” Automotive Supply Chain, July 2, 2013; Staff reporter, “Volkswagen Slashes Car Production at Russian Plat,” Reuters, September 7, 2014.

1.Russia is largely dependent on oil exports to drive its economy forward. Given the sharp fall in global oil prices that occurred in 2014 and 2015, what impact do you think this will have on FDI into Russia?

2.Volkswagen has signaled that it is going to stay the course in Russia, despite current political and economic headwinds. Why do you think it made this decision? What are the pros and cons of this decision? In your opinion, is it the correct decision?

1. Describe software process activities.

Much of the demand for Canadian agricultural output has come from other countries. Suppose, in 2014, the total demand for Canadian wheat was Q^D = 3244 - 283p, where price is measured in dollars per bushel and quantities in millions of bushels per year. Of those, the demand of Canadian consumers was Q^D_CND = 1244 - 83p. The supply of Canadian wheat in 2014 was Q^S = 1872 + 207p.

a) Compute the equilibrium price of Canadian wheat in 2014. What was the total revenue of Canadian wheat farmers?

Suppose the export demand for Canadian wheat expects to fall by 20% in 2015. On the other hand, the 2015's demand of Canadian consumers and the supply of Canadian wheat remain the same as the 2014's.

b) By how much do you expect the total revenue of the wheat farmers fall this year? (Hint: To find the export demand for wheat, you subtract the demand of Canadian consumers Q^D_CND from the total demand Q^D.

c) Suppose now the Canadian government wants to buy enough wheat to raise the price to the 2014 level. How much wheat would the government have to buy? How much would this cost the government?

1. Describe prototyping as used in system analysis and design.

On September 14th, 2023, the Canadian government threatened major grocers(Loblaws, Costco, Walmart, etc.) with new taxes if they failed to lower their foodprices.1Assume that the government imposes such taxes. Using a supply and demand diagram,show what effect this has on the equilibrium in the market for food. Does this help tolower food prices?If you were in charge of the government, how would you reduce food prices for Canadianconsumers?
