Robert Carr Bosanquet investigated trade in the Stone Age by excavations in 1901.

Historically, openness to free trade substantially increased in some areas from 1815 until the outbreak of World War I in 1914.

Trade openness increased again during the 1920s but collapsed (in particular in Europe and North America) during the Great Depression of the 1930s.

Trade openness increased substantially again from the 1950s onward (albeit with a slowdown during the oil crisis of the 1970s).

Economists and economic historians contend that current levels of trade openness are the highest they have ever been.

The modern concept of GDP was first developed by Simon Kuznets for a 1934 U.S.

After the Bretton Woods Conference in 1944, GDP became the main tool for measuring a country's economy.

The switch from GNP to GDP in the United States occurred in 1991.

GDP has been criticized for leaving out key externalities, such as resource extraction, environmental impact and unpaid domestic work.

Cryptocurrency uses a distributed ledger, or blockchain, to secure transactions.

Blockchain technology maintains a transparent and tamper-proof record of all transactions.

Cryptocurrencies like Bitcoin and Ethereum rely on complex algorithms to validate and confirm transactions.

Miners, individuals with specialized computers, validate transactions and are rewarded with newly minted cryptocurrency.

The value of cryptocurrencies is determined by supply and demand in the market, unlike traditional fiat currencies.

== History == In 1983, American cryptographer David Chaum conceived of a type of cryptographic electronic money called ecash.

Behavioral economics is primarily concerned with the bounds of rationality of economic agents.

Behavioral economics is still growing as a field, being used increasingly in research and in teaching.

The resurgence of psychology within economics, which facilitated the expansion of behavioral economics, has been linked to the cognitive revolution.

In The Theory of Moral Sentiments, Adam Smith wrote on concepts later popularized by modern Behavioral Economic theory, such as loss aversion.

A rejection and elimination of psychology from economics in the early 1900s brought on a period defined by a reliance on empiricism.

To boost the ability of economics to predict accurately, economists started looking to tangible phenomena rather than theories based on human psychology.

The opposite of inflation is deflation, a decrease in the general price level of goods and services.

The common measure of inflation is the inflation rate, the annualized percentage change in a general price index.

Moderate inflation affects economies in both positive and negative ways.

Today, most economists favour a low and steady rate of inflation.

Conceptually, inflation refers to the general trend of prices, not changes in any specific price.

These changes are not related to inflation; they reflect a shift in tastes.
