Question: Hayek's principal investigations in economics concerned capital, money, and the business cycle. Mises had earlier applied the concept of marginal utility to the value of money in his Theory of Money and Credit (1912), in which he also proposed an explanation for "industrial fluctuations" based on the ideas of the old British Currency School and of Swedish economist Knut Wicksell. Hayek used this body of work as a starting point for his own interpretation of the business cycle, elaborating what later became known as the "Austrian Theory of the Business Cycle". Hayek spelled out the Austrian approach in more detail in his book, published in 1929, an English translation of which appeared in 1933 as Monetary Theory and the Trade Cycle. There he argued for a monetary approach to the origins of the cycle. In his Prices and Production (1931), Hayek argued that the business cycle resulted from the central bank's inflationary credit expansion and its transmission over time, leading to a capital misallocation caused by the artificially low interest rates. Hayek claimed that "the past instability of the market economy is the consequence of the exclusion of the most important regulator of the market mechanism, money, from itself being regulated by the market process".
Is there an answer to this question: According to Hayek, what was the cause of the banks' wrongful allocation of funds?

Answer: artificially low interest rates

Problem: Carnival:

The term Carnival is traditionally used in areas with a large Catholic presence. However, the Philippines, a predominantly Roman Catholic country, does not celebrate Carnival anymore since the dissolution of the Manila Carnival after 1939, the last carnival in the country. In historically Lutheran countries, the celebration is known as Fastelavn, and in areas with a high concentration of Anglicans and Methodists, pre-Lenten celebrations, along with penitential observances, occur on Shrove Tuesday. In Eastern Orthodox nations, Maslenitsa is celebrated during the last week before Great Lent. In German-speaking Europe and the Netherlands, the Carnival season traditionally opens on 11/11 (often at 11:11 a.m.). This dates back to celebrations before the Advent season or with harvest celebrations of St. Martin's Day.

What country no longer celebrates Carnival?
