Veblen Effect

Capital formation: This refers to the net increase in the capital stock of a country, which includes physical capital (machinery, buildings) and human capital (skills, education). High savings: A high savings economy implies people are saving a significant portion of their income. Ideally, these savings are then invested to create new capital. Capital-output ratio (COR): This ratio measures the amount of additional capital needed to produce one unit of additional output (GDP). A high COR indicates that even with high savings and investment, the increase in output might be low. Hence, option D is the Correct Answer.

Statement 1 is correct. As per the data given in the Economic Survey 2019-2020, the weightage of food in the Consumer Price Index (CPI) Combined is 45.9% as compared to 24.4% in Wholesale Price Index (WPI). Statement 2 is correct. The CPI measures the average change in prices over time that consumers pay for a basket of goods and services, commonly known as inflation, whereas WPI does not measure the average change in prices. Statement 3 is incorrect. In April 2014, the RBI adopted the Consumer Price Index (CPI) as its key measure of inflation. Hence, option A is the correct answer.

Statement 1 is incorrect. Typically, the RBI uses open market operations to sell government securities to drain money from the system and control inflation. Buying government securities would inject money into the system, potentially fueling inflation further. Statement 2 is correct. Selling dollars in the market - If the rupee is rapidly depreciating, the RBI might intervene in the foreign exchange market by selling dollars from its reserves. This increased supply of dollars in the market can help stabilize the exchange rate and slow down the depreciation of the rupee. Statement 3 is correct. Lower interest rates in the US/EU make India a more attractive destination for foreign investment, leading to a large inflow of dollars. This causes the rupee to strengthen (appreciate). To prevent the rupee from appreciating too rapidly and hurting exporters, the RBI buys the excess dollars from the market.

Expansionary policies: Expansionary policies like increased government spending or lower interest rates can stimulate economic activity and consumer spending. This can lead to excess demand that outstrips supply, causing prices to rise. Fiscal stimulus: Similar to expansionary policies, fiscal stimulus through government spending injections can create an inflationary gap if it's excessive. Higher purchasing power: Higher purchasing power can contribute to demand-pull inflation. If people have more money to spend due to factors like wage increases or wealth accumulation, it can lead to increased demand for goods and services. Inflation-indexing wages: While inflation-indexing wages can contribute to a wage-price spiral in some cases, it's not necessarily a direct cause of demand-pull inflation. It can be a consequence of inflation rather than a primary driver. Rising interest rates: Rising interest rates generally act as a tool to cool down an economy and reduce inflation. They make borrowing more expensive and encourage saving, thereby reducing the money supply and aggregate demand. Therefore, the correct code is 1, 2, and 4.

Statement 1 is correct: Purchasing Power Parity (PPP) exchange rates are calculated by comparing the prices of the same basket of goods and services in different countries. Statement 2 is incorrect: India is not the sixth-largest economy in the world in terms of PPP dollars. It is currently the third largest economy in terms of PPP dollars, after China and the United States.
