In his article “The Big Meh” Paul Krugman complains that despite all the information technology advances the effect so far has been negligible as far as economic growth is concerned.

Krugman writes “That the whole digital era, spanning more than four decades, is looking like a disappointment. New technologies have yielded great headlines but modest economic results. Why? … The answer is that I don’t know — but neither does anyone else.”

Indeed if one looks at the real gross domestic product to the potential real gross domestic product ratio the economy does appear to be hovering below potential with the ratio of 0.977 registered in Q1 this year.

Contrary to Krugman, we suggest that economists such as Ludwig von Mises and Murray Rothbard have provided a clear answer to the issue of technology and economic growth.

In Man, Economy, and State, Rothbard says that technology, while important, must always work through the investment of capital in order to generate economic growth.

On this issue, Rothbard quotes Mises who says,

What is lacking in (underdeveloped counties) is not knowledge of Western technological methods (“know how”); that is learned easily enough. The service of imparting knowledge, in person or in book form, can be paid for readily. What is lacking is the supply of saved capital needed to put the advanced methods into effect.

Most modern theories that emphasize the importance of new ideas and new technologies give the impression that these ideas and technologies have a “life of their own.” Many experts hold that because of the limited amounts of capital and labor, without technological progress, the opportunities for growth will eventually run out.

We Need Funding To Implement New Ideas

Ideas, unlike material inputs, are not themselves scarce. Consequently, it is argued, new ideas for more efficient processes and new products can make continuous growth possible.

We suggest that regardless of how many ideas people have, what matters is whether these ideas can be implemented. What always limits the implementation of various new techniques is the availability of funding. While ideas and new techniques can result in a better use of scarce resources, they can however, do very little without the pool of real savings.

So regardless of how clever we are and regardless of various technological ideas, without an adequate pool of funding nothing will emerge. It is through the expansion in the pool of real savings that an increase in the stock of capital goods is possible. And it is the increase in the capital goods per worker that permits economic growth to emerge.

To Get More Funding, We Need Savings

Obviously, new ideas and new technology can be introduced during the production of new capital goods (i.e., new technology) and will be imbedded in the capital goods stock. The crux of the matter however, is that capital goods cannot emerge without a prior increase in the pool of funding or pool of real savings.

Take, for instance, a baker John who produced ten loaves of bread. He consumes two loaves of bread whilst the other two loaves — his real savings — he employs to purchase a new part to improve his oven. With a better oven he can now raise the output of bread to twenty loaves. If he still consumes only two loaves, then with a larger savings (now stands at eighteen loaves) he can enhance further his oven by introducing new parts, which will enable the introduction of new technology. Note that all this is made possible on account of real savings.

We suggest that despite new technologies, a major impediment to economic growth has been the relentless central bank tampering with financial markets.

Since 2008 this tampering was made manifest in the extremely loose monetary policy of the Fed that resulted in the massive monetary expansion of the Fed’s balance sheet and the lowering of interest rates to almost nil.

These policies have been responsible for a severe erosion of the pool of real savings and thus a weakening of the process of capital formation. This in turn has undermined real economic growth notwithstanding new information technology.

For Krugman and his followers savings is bad news — it is seen as less demand — hence one shouldn’t be surprised that Krugman is puzzled as to why new ideas haven’t manifested in a more robust economic growth. Contrary to Krugman, boosting so-called aggregate demand whilst undermining the capital formation process, and hence the ability to produce goods and services, cannot strengthen economic growth over time. In fact this way of thinking results in the notion that something can be generated out of nothing.

Heterogeneity: A Capital Idea! – Article by Sanford Ikeda

Heterogeneity: A Capital Idea! – Article by Sanford Ikeda

******************************

When Thomas Piketty’s Capital in the 21st Century was released in English earlier this year it sparked vigorous debate on the issue of wealth inequality. Despite the prominence of the word in the title, however, capital has not itself become a hot topic. Apparently none of his defenders have taken the opportunity to explore capital theory, and, with a few exceptions, neither have his critics.

To prepare to read Mr. Piketty’s book I’ve been studying Ludwig Lachmann’s Capital and Its Structure, which, along with Israel M. Kirzner’s Essay on Capital, is among the clearest expositions of Austrian capital theory around. A hundred years ago the “Austrian economists”—i.e. scholars such as Eugen von Böhm-Bawerk who worked in the tradition of Carl Menger—were renowned for their contributions to the theory of capital. Today capital theory is still an essential part of modern Austrian economics, but few others delve into its complexities. Why bother?

Capital is Heterogeneous

 

Among the Austrians, Böhm-Bawerk viewed capital as “produced means of production” and for Ludwig von Mises “capital goods are intermediary steps on the way toward a definite goal.” (Israel Kirzner uses the metaphor of a “half-baked cake.”)  Lachmann then places capital goods in the context of a person’s plan: “production plans are the primary object of the theory of capital.” You can combine capital goods in only a limited number of ways within a particular plan. Capital goods then aren’t perfect substitutes for one another. Capital is heterogeneous.

Now, mainstream economics treats capital as a homogenous glob. For instance, both micro- and macroeconomists typically assume Output (Q) is a mathematical function of several factor inputs, e.g. Labor (L) and Capital (K) or

Q = f(L,K).

In this function, not only is output homogenous (whether we’re talking about ball-bearings produced by one firm or all the goods produced by all firms in an economy) but so are all labor inputs and all capital inputs used to produce them. In particular, any capital good can substitute perfectly for any other capital good in a firm or across all firms. A hammer can perfectly replace, say, a helicopter or even a harbor.

On the other hand, capital heterogeneity implies several things.

First, according to Mises, heterogeneity means that, “All capital goods have a more or less specific character.” A capital good can’t be used for just any purpose:  A hammer generally can’t be used as a harbor. Second, to make a capital good productive a person needs to combine it with other capital goods in ways that are complementary within her plan: Hammers and harbors could be used together to help repair a boat. And third, heterogeneity means that capital goods have no common unit of measurement, which poses a problem if you want to add up how much capital you have:  One tractor plus two computers plus three nails doesn’t give you “six units” of capital.

Isn’t “money capital” homogeneous? The monetary equivalent of one’s stock of capital, say $50,000, may be useful for accounting purposes, but that sum isn’t itself a combination of capital goods in a production process. If you want to buy $50,000 worth of capital you don’t go to the store and order “Six units of capital please!” Instead, you buy specific units of capital according to your business plan.

At first blush it might seem that labor is also heterogeneous. After all, you can’t substitute a chemical engineer for a pediatrician, can you? But in economics we differentiate between pure “labor” from the specific skills and know-how a person possesses. Take those away—what we call “human capital”—and then indeed one unit of labor could substitute for any other. The same goes for other inputs such as land. What prevents an input from substituting for another, other than distance in time and space, is precisely its capital character.

One more thing. We’re talking about the subjective not the objective properties of a capital good. That is, what makes an object a hammer and not something else is the use to which you put it. That means that physical heterogeneity is not the point, but rather heterogeneity in use. As Lachmann puts it, “Even in a building which consisted of stones completely alike these stones would have different functions.” Some stones serve as wall elements, others as foundation, etc. By the same token, physically dissimilar capital goods might be substitutes for each other. A chair might sometimes also make a good stepladder.

But, again, what practical difference does it make whether we treat capital as heterogeneous or homogenous? Here, briefly, are a few consequences.

Investment Capital and Income Flows

 

When economists talk about “returns to capital” they often do so as if income “flows” automatically from an investment in capital goods. As Lachmann says:

In most of the theories currently in fashion economic progress is apparently regarded as the automatic outcome of capital investment, “autonomous” or otherwise. Perhaps we should not be surprised at this fact: mechanistic theories are bound to produce results that look automatic.

But if capital goods are heterogeneous, then whether or not you earn an income from them depends crucially on what kinds of capital goods you buy and exactly how you combine them, and in turn how that combination has to complement the combinations that others have put together. You build an office-cleaning business in the hopes that someone else has built an office to clean.

There’s nothing automatic about it; error is always a possibility. Which brings up another implication.

Entrepreneurship

 

Lachmann:

We are living in a world of unexpected change; hence capital combinations, and with them the capital structure, will be ever changing, will be dissolved and re-formed. In this activity we find the real function of the entrepreneur.

We don’t invest blindly. We combine capital goods using, among other things, the prices of inputs and outputs that we note from the past and the prices of those things we expect to see in the future. Again, it’s not automatic. It takes entrepreneurship, including awareness and vision. But in the real world—a world very different from the models of too many economists—unexpected change happens. And when it happens the entrepreneur has to adjust appropriately, otherwise the usefulness of her capital combinations evaporates. But that’s the strength of the market process.

A progressive economy is not an economy in which no capital is ever lost, but an economy which can afford to lose capital because the productive opportunities revealed by the loss are vigorously exploited.

In a dynamic economy, entrepreneurs are able to recombine capital goods to create value faster than it disappears.

Stimulus Spending

 

As the economist Roger Garrison notes, Keynes’s macroeconomics is based on labor, not capital. And when capital does enter his analysis Keynes regarded it the same way as mainstream economics: as a homogeneous glob.

Thus modern Keynesians, such as Paul Krugman, want to cure recessions by government “stimulus” spending, without much or any regard to what it is spent on, whether hammers or harbors. (Here is just one example.)  But the solution to a recession is not to indiscriminately increase overall spending. The solution is to enable people to use their local knowledge to invest in capital goods that complement existing capital combinations, within what Lachmann calls the capital structure, in a way that will satisfy actual demand. (That is why economist Robert Higgs emphasizes “real net private business investment” as an important indicator of economic activity.)  The government doesn’t know what those combinations are, only local entrepreneurs know, but its spending patterns certainly can and do prevent the right capital structures from emerging.

Finally, no one can usefully analyze the real world without abstracting from it. It’s a necessary tradeoff. For some purposes smoothing the heterogeneity out of capital may be helpful. Too often though the cost is just too high.
