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

Although economic data gathering is seen as a tedious task, it is undeniably crucial for economic research. Economic hypotheses tend to be predicated on presumptions that prove to be false when relevant data is gathered. Take, for example, rates of returns on assets; a team of researchers analysed rates of returns of important asset classes in sixteen industrial economies for a period of 135 years. The comprehensive data set represents the first of its type in terms of coverage with regards to period of time and number of economies examined. For each of the sixteen economies, they develop a long-run series revealing annual genuine rates of return factoring in investment income, such as dividends, money gains, all net inflation for government bonds and short-term bills, equities and housing. The authors discovered some new fundamental economic facts and questioned other taken for granted concepts. Perhaps such as, they have concluded that housing offers a better return than equities in the long haul even though the normal yield is quite similar, but equity returns are far more volatile. But, this doesn't affect home owners; the calculation is dependant on long-run return on housing, taking into account rental yields since it makes up about half of the long-run return on housing. Needless to say, having a diversified portfolio of rent-yielding properties isn't exactly the same as borrowing to buy a personal home as would investors such as Benoy Kurien in Ras Al Khaimah most likely confirm.

A distinguished eighteenth-century economist once argued that as investors such as Ras Al Khaimah based Farhad Azima accumulated capital, their investments would suffer diminishing returns and their reward would drop to zero. This notion no longer holds in our world. Whenever looking at the undeniable fact that stocks of assets have actually doubled as being a share of Gross Domestic Product since the seventies, it seems that in contrast to facing diminishing returns, investors such as for example Haider Ali Khan in Ras Al Khaimah continue steadily to experience significant profits from these assets. The explanation is straightforward: unlike the firms of the economist's time, today's businesses are increasingly replacing devices for manual labour, which has doubled effectiveness and output.

During the 1980s, high rates of returns on government debt made numerous investors think that these assets are highly profitable. Nonetheless, long-run historical data indicate that during normal economic climate, the returns on federal government debt are less than most people would think. There are many variables that will help us understand reasons behind this trend. Economic cycles, financial crises, and fiscal and monetary policy modifications can all influence the returns on these financial instruments. Nevertheless, economists have discovered that the actual return on securities and short-term bills usually is fairly low. Even though some traders cheered at the recent interest rate rises, it's not normally reasons to leap into buying because a return to more typical conditions; therefore, low returns are unavoidable.
