Fed Pause Promises Financial Disaster The indication is that inflationary expectations have become entrenched and strongly footed in world markets. As a result, the risk of global stagflation has become significant. A drawn-out inflationary process always precedes stagflation, anathema to the so-called Phillips Curve.

Pakistan: Is it Cost-Push Inflation? With CPI already spiking 11.8 percent for the first ten months of the fiscal year, the average CPI inflation for the same period last year stood at 22.35 percent. Some economists insist the current bout of inflationary pressures is spawned by increasing prices of fuel, food, raw materials, transportation, construction materials, elimination of energy subsidies, etc as indicated by the spike in the wholesale price index (WPI), which rose 21.99 per cent in April from a year earlier. Pakistan is experiencing ______ inflation
cost push inflation
Tight Money Won't Slay Food, Energy Inflation It's important to differentiate between a general increase in priceslong dash—a situation in which aggregate demand exceeds their aggregate supplylong dash—and a relative price shock. For example, a specific shock to energy prices can become generalized if producers are able to pass on the higher costs. So far, global competition has made that difficult for companies, while higher input costs have largely been neutralized by rising labor productivity. Since 2003, core inflation has averaged less than 2 percent a year in the 30 major economies. History also suggests the Fed's gamble that slowing growth will shackle core inflation is a winning wager. The risk is that if U.S. consumers don't believe price increases will slow, growing inflation expectations may become self-fulfilling. The news clip refers to ______ inflation when it discusses rising production costs. "Rising labor productivity" can neutralize the effect on the inflation rate of "higher input costs" because ______
cost-push; it increases short-run aggregate supply and long-run aggregate supply with no slowdown in aggregate demand growth side note: "Slowing growth" can reduce inflationary pressure if aggregate demand growth slows.
Stagflation occurs when _______
costs increase
An unexpected increase in aggregate demand ______ rate, which is shown by ______ the short-run Phillips curve.
decreases unemployment and increases the inflation; a movement up along
Official: China May Face Heavy Inflation Pressure China is expected to face great inflationary pressure in the future due to higher costs and an abundant global money supply, a senior Chinese official said in an article published Tuesday. He said inflation in China is also the result of excessive global liquidity from loose monetary policies adopted by developed nations, China's lending expansion, and a pile-up of outstanding foreign exchange funds. China's consumer price index (CPI), a main gauge of inflation, rose 4.9 percent year on year in February, the same level as in January. The CPI data for March is scheduled to be released this week and is estimated to show a rise above 5 percent. Read the news clip, then answer the following question. China is experiencing a ______ inflation caused by ______.
demand-pull; loose monetary policy, which increases aggregate demand

Iran Postpones Cutting Gasoline Subsidies Inflation is about 10 percent and the unemployment rate is about 14 percent. Earlier this month Iran's main audit body slammed the government's plan to scrap gasoline subsidies, warning that implementing such a reform might result in unrest. The government also intends to scrap subsidies on natural gas, which most Iranians use for cooking and heating, as well as electricity, but the new prices are still not known. However, in recent weeks some households have received electricity bills with nearly sevenfold price increases. The graph shows Iran's short-run Phillips curve and long-run Phillips curve when the natural unemployment rate is 10 percent and the expected inflation rate is 12 percent a year. Draw a point to show the current unemployment rate and inflation rate according to the news clip. Suppose Iran removes the subsidies and consumers don't know what the higher prices will be.

Getting a Raise: Why It's Not Happening Didn't get a raise this year? Blame inflation. American wages didn't budge last month, according to Labor Department data released Wednesday. And with inflation remaining at near zero, experts say it could be quite a while before many workers see their next raise. While stagnant prices are a boon for consumers on supermarket checkout lines, they can be hard on workers' bottom lines. Wages typically track inflation, soaring higher when prices take off. In fact, some say wages tend to feed inflation. That was the case in the 1970s, when wage growth picked up after prices soared. But pricing pressures are weaker today, with the consumer price index, a measure of inflation, unchanged in July from the previous month. Starting from a long-run equilibrium, _______. "Wages typically track inflation, soaring higher when prices take off." In this situation, the economy is experiencing _______ inflation. An economy experiences _______ inflation when "wages tend to feed inflation."

Stagflation Is Back. Here's How to Beat It Three decades ago, in a bleak stretch of the 1970s, an economic phenomenon emerged... stagflation. ... leading many to argue that the world had reached its limits of growth and prosperity. ... Fortunately, there is a better way forward than we took after 1974. We need to adopt coherent national and global technology policies to address critical needs in energy, food, water, and climate change. ... There is certainly no shortage of promising ideas, ... Solar power ... high-mileage automobiles (like plug-in hybrids with advanced batteries), green buildings, carbon capture, cellulose-based ethanol, safe nuclear power, and countless other technologies on the horizon can reconcile a world of growing energy demands with increasingly scarce fossil fuels and rising threats of human-made climate change. As for food supplies, new drought-resistant crop varieties have the potential to bolster global food security in the face of an already changing climate. New irrigation technologies can help impoverished farmers move from one subsistence crop to several high-value crops year round. ...
