Recent research highlights just how economic data might help us better understand economic activity more than historic assumptions.

During the 1980s, high rates of returns on government debt made numerous investors believe these assets are highly profitable. Nevertheless, long-run historic data indicate that during normal economic climate, the returns on federal government bonds are lower than people would think. There are many factors which will help us understand this trend. Economic cycles, economic crises, and fiscal and monetary policy modifications can all impact the returns on these financial instruments. Nonetheless, economists have found that the actual return on bonds and short-term bills frequently is fairly low. Although some traders cheered at the recent rate of interest rises, it is really not necessarily reasons to leap into buying as a reversal to more typical conditions; therefore, low returns are inescapable.

Although data gathering sometimes appears as a tiresome task, it is undeniably important for economic research. Economic theories tend to be based on presumptions that prove to be false when useful data is collected. Take, as an example, rates of returns on investments; a team of researchers analysed rates of returns of important asset classes across sixteen advanced economies for a period of 135 years. The comprehensive data set represents the very first of its type in terms of coverage with regards to time period and number of economies examined. For each of the 16 economies, they develop a long-term series demonstrating annual real rates of return factoring in investment earnings, such as dividends, capital 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. Perhaps especially, they have concluded that housing offers a superior return than equities over the long haul although the average yield is quite comparable, but equity returns are much more volatile. Nonetheless, this does not apply to home owners; the calculation is founded on long-run return on housing, taking into account rental yields because it makes up half of the long-run return on housing. Needless to say, owning a diversified portfolio of rent-yielding properties isn't the exact same as borrowing to buy a family home as would investors such as Benoy Kurien in Ras Al Khaimah most likely attest.

A distinguished eighteenth-century economist one time argued that as investors such as Ras Al Khaimah based Farhad Azima accumulated wealth, their investments would suffer diminishing returns and their return would drop to zero. This idea no longer holds within our global economy. Whenever looking at the fact that stocks of assets have doubled being a share of Gross Domestic Product since the seventies, it appears that in contrast to dealing with diminishing returns, investors such as Haider Ali Khan in Ras Al Khaimah continue steadily to reap significant profits from these investments. The reason is easy: contrary to the businesses of the economist's time, today's businesses are rapidly replacing devices for manual labour, which has certainly boosted efficiency and productivity.
