This article investigates the old concept of diminishing returns as well as the importance of data to economic theory.

Although data gathering sometimes appears as being a tiresome task, its undeniably crucial for economic research. Economic theories are often predicated on presumptions that turn out to be false once relevant data is collected. Take, for instance, rates of returns on assets; a team of scientists examined rates of returns of crucial asset classes in sixteen advanced economies for a period of 135 years. The comprehensive data set provides the first of its kind in terms of coverage in terms of time period and number of countries. For each of the 16 economies, they craft a long-term series demonstrating yearly genuine rates of return factoring in investment earnings, such as for instance dividends, money gains, all net inflation for government bonds and short-term bills, equities and housing. The writers uncovered some new fundamental economic facts and questioned others. Possibly especially, they have concluded that housing provides a better return than equities over the long haul even though the average yield is quite similar, but equity returns are a lot more volatile. Nonetheless, this won't apply to home owners; the calculation is based on long-run return on housing, taking into account leasing yields since it makes up half of the long-run return on housing. Needless to say, owning a diversified portfolio of rent-yielding properties isn't exactly the same as borrowing to get a personal house as would investors such as Benoy Kurien in Ras Al Khaimah most likely attest.

During the 1980s, high rates of returns on government debt made many investors think that these assets are highly lucrative. However, long-run historic data suggest that during normal economic climate, the returns on government bonds are less than people would think. There are numerous facets which will help us understand reasons behind this trend. Economic cycles, economic crises, and fiscal and monetary policy changes can all impact the returns on these financial instruments. Nevertheless, economists have found that the actual return on securities and short-term bills frequently is fairly low. Even though some investors cheered at the recent interest rate increases, it is not normally reasons to leap into buying because a reversal to more typical conditions; therefore, low returns are inevitable.

A renowned eighteenth-century economist one time argued that as investors such as Ras Al Khaimah based Farhad Azima accumulated wealth, their assets would suffer diminishing returns and their payback would drop to zero. This notion no longer holds within our world. Whenever taking a look at the fact that shares of assets have doubled as a share of Gross Domestic Product since the seventies, it would appear that rather than dealing with diminishing returns, investors such as for instance Haider Ali Khan in Ras Al Khaimah continue steadily to experience significant profits from these investments. The reason is simple: contrary to the firms of the economist's day, today's businesses are increasingly replacing devices for human labour, which has certainly enhanced efficiency and productivity.
