Yin and Yang are two ancient concepts in Taoism (a Chinese philosophical tradition) that are more widely known for the symbol that represents them than for what they actually mean.
If the name doesn't ring a bell, maybe this image will:
Although the symbol depicts them together (and there is a reason for this, as we will see later), Yin and Yang are, in essence, two distinct concepts. The first is related to the earth, darkness, and passivity; it is associated with femininity. The second is linked to the sky, light, and activity; it is associated with masculinity.
Yin and Yang, however, have a greater philosophical and conceptual impact in terms of what they represent as a whole, rather than in isolation. Taoism, in fact, explains that these two “forces” do not exist individually, but coexist in harmony. They are two aspects of a whole.
This synergy leads us to perhaps the most important meaning they symbolize: balance.
Like almost every aspect of daily life, Yin and Yang represent the dialogue and balance between: cold and heat, summer and winter, good and evil, and countless other mundane examples.
As one might expect, this age-old concept also applies to taxes (which, incidentally, are also an age-old institution).
“Yin and Yang in Taxation”
The next question, asked with a touch of skepticism, is: What is the relationship between Yin and Yang and taxes?
Although at first glance they may not seem to be related, Yin and Yang are concepts that also apply to the world of taxes.
If we stop to think about the term “tax” and its traditional connotation, taxes are nothing more than “impositions” of conditions that make transactions more burdensome (or, colloquially, more expensive), in pursuit of a common revenue stream. Thus, the value-added tax makes consumption more expensive; the income tax makes earning profits more expensive; the property tax makes the right to own property more expensive. In short, taxes make the economic dynamics of markets more expensive.
That said, we know that taxes are essential resources that enable the government—in theory—to have the tools it needs to fulfill its constitutional purposes: health care, education, justice, etc.
Given this situation, the central question here is: What is the balance between the tax rate and the government’s need to collect revenue to fulfill its objectives?
Welcome to “The Yin and Yang of Taxation”: The Laffer Curve.
Arthur Laffer is an American economist who served as an advisor to President Ronald Reagan's administration from 1981 to 1989.
Among other valuable ideas, Laffer is recognized worldwide for having proposed the notion that there is a tax rate capable of maximizing tax revenue. An optimal tax equilibrium. The tension between the tax rate and the revenue target. This concept was later termed “the Laffer curve.”.
The key point here is that raising the tax rate—perhaps counterintuitively—does not always lead to higher tax revenue (or greater tax efficiency). On the contrary, it may be that, beyond a certain level, tax revenue declines, and the increase becomes counterproductive to the intended goal.
The explanation behind Laffer’s conclusions centers on the following assertion: a lower tax rate encourages the economic activity in question (consumption, business investment, or asset acquisition). This leads to an increase in the pool of taxable (or revenue-generating) transactions. An incentive for formal economic activity.
The practical application of the Laffer curve varies depending on the economic characteristics of each country. For example, the equilibrium rate in an economy like Brazil’s will not be the same as in an economy like Uruguay’s. Nevertheless, the concept is a valuable tool when implementing public policies aimed at promoting growth.
In the case of Paraguay—a landlocked, developing country eager for progress—experience has shown that tax rates that are competitive with the rest of the region have led to an increase in foreign direct investment, economic growth, and tax revenue.
We still need to discuss the efficiency of public spending.
In the meantime, the way forward is to keep in mind the ancient principle of Yin and Yang and to continue striving for fiscal balance.
