Through this research, Lewis and his colleagues examined some of the conditions that have led to the disparity between rich and poor countries. His findings about why some countries experience robust growth while others remain stagnant are surprising and insightful. He recently sat for an interview with TCS editor Nick Schulz.
NICK SCHULZ: Mr. Lewis, thanks for joining us.
Describe how you and the McKinsey Global Institute came to do the work that went into this book.
WILLIAM LEWIS: Well, it is unusual that a private sector firm like McKinsey would do this kind of work and so that story itself is interesting. The other aspect that is also relevant here is that none of us anticipated when we started the McKinsey Global Institute that 15 years later we would be looking at a book like this and that I would be talking to you about a subject like this.
The basic idea back in 1990 was that there were several big trends going on in the world, which were not very well understood. Globalization -- people were beginning to use the word globalization -- and it was not very well understood and nobody knew where it might lead. Secondly, there were other changes, maybe more in
SCHULZ: What sort of specific work did you set out to do?
LEWIS: Well, it was a step by step process. I spent six months traveling around the world talking to my partners and to well-informed people of one kind or another, either academics or business people or journalists, about what we should do and didn't get a very clear picture from that. However, serendipitously, I happened to see one Saturday morning before I dashed off to play tennis those statistics in the Economist that are buried at the back that happen to show the latest results of GDP per capita using purchasing power parity exchange rates. What that shows (and this is back in 1990) was that the
What I realized when I saw those numbers was that if they were right, then the conventional wisdom was wrong. That would be a very, very important thing to get straight for all sorts of reasons. The idea quickly emerged in these discussions that if this is true, given that employment is about the same in many countries, it's got to be a productivity difference; and if the US has a productivity lead, it's got to be in services because everybody knew that US manufacturing had gone to the dogs. That was the conventional wisdom at that time.
SCHULZ: The title of the book came to be the Power of Productivity. Now how did productivity come to loom so large in what you studied?
LEWIS: Well simply because productivity is the best single measure of what leads to differences in economic performance. Even though GDP per capita is the all-encompassing measure, GDP per capita is determined primarily, almost entirely, by productivity. People basically work in order to have a place to sleep and something to eat and so on and so forth. The huge differences around the world are the efficiencies with which they work -- their productivity. So it is the power of productivity that determines what the global economic landscape looks like and because there are such differences, we have quite a number of severe issues that face us today.
SCHULZ: You say in your book that in order to really understand a country's economic performance, you need to conduct analysis at the level of individual industries and sectors. Why is that?
LEWIS:
The paradox was that in the 90s stories on the front pages of the New York Times, the Wall Street Journal, and the Economist were all about how the Japanese manufacturing industries through trade were driving US manufacturing industries into the ground and virtually wiping them out. And of course that did happen in consumer electronics -- the
What we found is that
And yet, the traded part of an economy is always a tiny fraction of the total GDP. A rule of thumb is that it's roughly at most 15 percent of the GDP.
So what that says is that the standard of living is determined because the productivity of the country is determined by what happens outside these traded goods. Productivity of a country in total -- the average productivity -- is the average productivity of every single worker. So in that sense, every worker is equally important. If you have low productivity in the non traded parts of manufacturing and in the huge domestic service industry -- such as retailing and housing construction and so on -- you are going to have low average productivity even though you may have a handful of industries like automotive and machine tools and steel where you have the highest productivity in the world.
SCHULZ: So even though these may not be the sexiest industries and the ones that journalists especially like to focus on, they can be critically important. Now what did you find in the case of
LEWIS: Well of course what it showed was that, yes in those industries,
We got these results back in 1992 with our point of view about
SCHULZ: And people talk about a housing bubble in the
LEWIS: Oh yes now they have forgotten what a real bubble is like.
The way this now plays into the debate today is to say that all these sectors are in the same economy. And all the so-called
SCHULZ: How can there be such a disparity between the
LEWIS: When you come to understand retailing, [you realize] that the industry of retailing has gone through its own evolution. 50 years ago or so, retailing was much more similar in the rich countries to each other than it is today in that it was primarily dominated by general stores of relatively small scale and mom and pop small shop operations. And what has happened over the last 60 years is that innovations have occurred in retailing and new formats of much higher productivity then these former formats have developed. The most obvious being the so called big box epitomized by Wal-Mart, which has productivity something like five times the productivity of a normal general store of the 1950's. And so the story in retailing is how many of these high productivity formats are part of the mix of stores in retailing and how much of retailing is still like it was in 1950. In other words, the evolution in retailing has progressed at far different rates in these countries around the world.
So in the
So then you get to the next level. OK, why haven't entrepreneurs and managers of capital and others that have invested in retailing and created businesses of operations and firms and actual formats in retailing [managed to do it] at the same rate? Why has it been different? And there you get into a huge area of micro rules and regulations and incentives on managers so that basically they end up doing different things.
In the
SCHULZ: What kind of obstacles?
LEWIS: In terms of the big operations, they have great difficulty in
So you get the case where I just read in the paper just the other day that Carrefour which is probably the most successful international retailer -- it has high productivity and it has been at the international game much longer than Wal-Mart and it is successful in most places around the world -- has actually just given up on Japan after trying for two decades to build stores and to create what they've been able to create most other places in the world.
At the same time, there are huge incentives for the mom and pops not to close down, to continue to limp along. They come from many directions. First of all, the mom and pops just simply get subsidized loans. And they have no trouble paying off those loans because they are sitting on some of the most valuable real estate in the world, especially during the bubble time. So basically when they die, their estate would have no trouble paying off the loans so they don't have a cash flow problem which they would have if they weren't subsidized in terms of loans. And then there is a strong incentive for them not to sell in the tax code in Japan in that capital gains taxes are very high in Japan and estate taxes are very low so there is a huge incentive for these mom and pops to hang on to their land and basically pass it on to the next generation. So those things are the main factors that have just lead retailing to stagnate in
SCHULZ: Now I want to shift gears a little bit and just look at one or two things that you discovered that do not account for diminished productivity from one country relative to another. For example, one finding that might surprise some people is that the education level of the labor force isn't nearly as important for overall economic performance for a nation as commonly thought. You say in the book that importance has been "taken way too far."
LEWIS: Right.
SCHULZ: In other words that education is not the way out of the poverty trap. Now how do you reach that conclusion?
LEWIS: By sifting through evidence primarily from two directions. Interestingly enough, we got the first hint of this when we were studying the
So when we first came out with this conclusion, it just really staggered Bob Reich and others. Bob Reich was US Secretary of Labor and a great advocate at that time of the German apprenticeship system and felt like we just needed to train American labor better. And we showed that something like 40 percent of the unemployed in
But more importantly, you can take the
I am a Democrat, by the way, and I voted for
The great bulk of the evidence about education came from competent multinational corporations of any nationality. Showing they could go virtually anywhere in the world and take the local workforce and train it to come close to home country productivity.
And then, sort of the clinching evidence was we then looked at some other industries. We compared the construction industry in the
SCHULZ: Wow.
LEWIS: Just because people are not educated does not mean that they are incapable, which is a mistake educated people in the West often make -- and not just the West but probably in
SCHULZ: That earlier comment about your politics leads into one of the next questions I want to ask. This might come as a surprise to some folks who work in development economics, but many people don't realize the destructive power that large government bureaucracies can have on economic development.
Now when I read your book, I did not detect any sort of anti-government ideology at work. And your comments about whom you voted for speak to that. So what are your experiences that led you to this conclusion about the role that the large government and government bureaucracies can have on productivity and economic efficiency?
LEWIS: That's an interesting story. I will try to make it short. We got the first hint of this in
The problem that we found was that basically the most productive multinationals in some industries were not going into these countries in the way that we expect them to; or they were not expanding in these countries nearly as fast as we thought they had the opportunity to do. And so we tried to get at why is that, because their productivity was clearly multiples of the domestic producers they would be competing against. And we did interviews with these people because thorough McKinsey we know these firms in a different way and so we could talk to them.
And I report about the interview with Carrefour in
We found that their competitors were doing a number of things that Carrefour could not or would not do in their business practices. Imports were flooding into
That led to the question, okay, but this problem of competing with so-called informal firms, as these kinds of firms were known, has to have been true for rich countries at some stage of their development also. When they were poor, how did they ever get over this problem?
And so you think about it and say, well, I wonder if they got over this problem because it didn't matter. That the taxes were so low because the governments were so small that it didn't matter if there was this differential playing field. If they had productivity four times as high, they basically could make money even though they paid taxes and their competitors didn't because the taxes themselves were so low.
And so we did compare what the size of all governments in the
But then you say: well, the rich countries today have high taxes and big government. So why doesn't that matter? Well the reason it doesn't matter today is that everybody is formal. Informality fades out because as you go, the only way you get high productivity operations throughout the whole economy is to have it dominated by big firms of scale where there is substantial division of labor and high productivity and so on and so forth. And so that means that all firms pay these taxes so that the playing field is again equal because everybody pays the same fraction of taxes.
The no man's land that the poor countries have gotten into now is that they've gone to big governments before they can afford it and before informality has been phased out or driven out by high productivity operations, so they have both big government and informality. And that's a recipe for disaster for the reasons I have explained in terms of the competitive dynamics at the micro level. As a result you would predict, well, maybe informality is increasing. And sure enough when you look at it in
SCHULZ: What can a developing country like
LEWIS: It is a problem because once you are there, as everybody knows from just simple kindergarten politics, it's very difficult to cut government services for people.
And we look for examples. All our instincts are to look and see who has done this before, rather than to theoretically try to think about how might this be done, how has this been done before? There are four relevant countries --
SCHULZ: Right.
LEWIS: But
SCHULZ: And the other problem is that we now have instances where the government itself is actively encouraging the informal sectors in some areas. Is that true?
LEWIS: That's certainly true and it gets all wrapped up in other kinds of efforts that are well-motivated but really not going to lead these countries out of their poverty trap, such as micro finance and property rights for squatters and this that and the other. All those things are worth doing but they are not going to solve the problem -- as long as the bigger conditions exist and are preventing the formation of the formal sector at a rapid rate where you can benefit from economies of scale and division of labor and training along particular functional skill lines and so on and so forth. That's the way countries get rich.
SCHULZ: We hear a lot about competition and trade distortions, subsidies and tariffs and that sort of thing. And certainly they exist in the
LEWIS: Well, the distortions to competition in the great width of the economy are more severe in poor countries. As you go to progressively poorer countries, there is that sort of picture that shows up without any question. So yes,
SCHULZ: And when you are talking about these more productive sectors and firms, a lot of time you are talking about large western multinational companies. You mentioned Carrefour. But a lot of these companies are perceived sometimes in the media, sometimes by NGOs and the like, as threats to developing countries. And indeed in
LEWIS: Well for the foreign direct investments, it's a win-win game - it's a win for the poor countries because they get capital to expand capacity and produce more goods and services. Because it's investment in the country, it employs local labor. And local labor is always 2/3 of the cost structure of any operation, so 2/3 of the value created by the new firms automatically and immediately goes to local labor through the salaries that are paid to local labor. And their productivity is so high they pay well relative to what you can make as an informal worker in those countries. That's how wages go up as a result of productivity improvement and that's how countries get richer. That's the growth dynamic; that's how growth actually occurs, it's for people to take more productive jobs that lead to higher wages that which then lead to more demand for things that people with higher wages want and that's how you grow - that's the growth dynamic. So that's the winner.
The reason it works is because the consumers in these countries end up getting a better combination of price and service and quality and convenience than they are able to get otherwise and they go to shop at these places. So the consumer is better off because the consumer gets a better deal.
Now that is not true in every case and obviously there have been some multi-nationals who have not done well and not succeeded. But for the last couple of decades the story of the results of foreign direct investment is a win-win story for everybody.
Populism is against this in many of these poorer countries. And one of the reasons that it is successful is because the secret enemies to globalization -- in particular to this foreign direct investment -- are the local domestic producers. And now multi-nationals have shown that they can go and invest substantial amounts of money with the benefits to the economy, the local economy that I have described, across the globe without any questions. And they can operate there at productivity significantly higher than the local producers and under price them and either drive them out of business or force them to improve in the way that the multi-nationals operate. And so, the domestic producers are against this because they don't want this in competition. I mean no producer -- no producer -- ever asked for more competition. So these domestic producers are really the secret enemies of globalization and they are having a lot of influence against it.
SCHULZ: Why are consumer interests so weak, and not just in developing countries but also in developed nations? You touch on this in your book when you talk about domestic producers and their political clout. But what if anything can be done to strengthen the relative status of the consumer to the governing elites and the producers in any country?
LEWIS: I tried to figure this out because the literature on this is actually very weak and there is not much of it. I did have a Yale law school graduate do some research here and I looked into the literature [to see] what had led to the pro-consumer rights laws and regulations in the US that are so different from almost any other country and certainly any poor country. And the startling thing that emerged from this at first was how long ago these laws were actually put in place in the
As I say in the book, the Sherman Act of 1890 probably had more good pro-consumer competition policy and direction than most countries in the world have today. And of course it took a long time for the Sherman Act to work its way through the
But certainly by the late 20s and early 30s when all the reforms occurred in US, we were seeing the benefits of this and the example I often give of this is that it was in the early 1930s that insider trading became illegal in the
So the question becomes why was the
So you suddenly had a few million farmers beginning to view themselves as consumers. And that thinking didn't have much manifestation because we were primarily an agrarian society for the next 100 years. But certainly by the time the industrial revolution got started, the thinking in this country was so oriented towards consumption and consumers, relative to everybody else -- certainly nothing like it is today -- but relative to everybody else. That these laws naturally came into place when there began to be a need for them as a result of the industrial revolution and the issues that it raised over monopolies and special interests and influence on government and special privileges and this that and the other. And so basically the
However, the other side of the coin, and the thrust, the modern thrust, that conflicted with this so strongly in the first half of the 20th century and even mid century, was the thrust of, I will call it, planning - the Soviet Union illustrating that to the greatest degree, with a fully centrally planned economy. It is interesting how many economists and how many intellectuals and how many other people really thought that was the way to create the superior economy because smart people could just figure out what should be done.
And I think I have in the book this great quote from Gunnar Myrdal right after he won the Nobel Prize. It must have been back in the 1950s. It said "what the poor countries or the developing countries need is super planning." And that kind of thinking just permeated the poor world, and also the developing institutions. There were vestiges of that thinking left in the middle 1970s when I was at the World Bank and it still echoes around in Delhi when we were there working on India. Nehru was a great admirer of the Soviet Central Planning System. He and the leaders in India thought, and in some respects probably still think, at least some of them are smart enough to figure out how all this should happen.
And of course the way you make a plan happen is by having a plan for production, not for consumption. There is no way you can plan or affect the individual choices that the people make as individuals when they buy things, but you certainly can affect strongly what they have to buy through production planning. And so this whole idea of the producer orientation was aided and abetted in modern times by the planning idea.
It's easy to see where it came from in feudal times -- that basically the people who owned the capital and the landowners could control what happens. They were the only ones who had the ability to do anything. So this whole battle between individual rights, political philosophies based on individual rights, and what immediately comes from those political philosophies -- namely ideas of consumer rights -- have permeated to a relatively small degree around the world.
And yet, as you can tell from my argument, that's the only way I can see for this lock of special interests and privileges that is holding back so many of these poor countries and some of the rich countries. The only way that can be overcome is through this consumer rights notion because democracy is necessary but not sufficient. It is necessary because it's the only way you can affect change of this kind, but it is not sufficient because, democracies have this theoretical weaknesses that lot of people have always recognized, that a majority or an effective majority can gang up on the minority and for short-term or medium-term gains can actually extract privileges or special benefits compared to what the other gets. And in
So the thing that happens, the way to break that if you put any stock in the
SCHULZ: What are you working on now? What are areas that you think where further study or inquiry are required to round out that picture of the path to development and wealth?
LEWIS: Well let me just say first that I don't think additional countries in the sample are necessary. I don't think they will add anything to the fundamental pattern that showed up.
What I am mulling over in the back of my mind is of course where the book left off. Namely, how do you break through the special interests that are holding back development in the poor countries? And if it is rooted, as I argue, in political philosophy, how do you get the spread of this old idea in the West (and in particular in the
And you know, I am not tying it to anything today yet. But you know, the notion that for the
SCHULZ: And just in terms of what you are working on right now, what sort of research are you doing?
LEWIS: I am not doing any new research. The Global Institute, since I retired, has gone to working on things that are more directly associated with our clients and their problems of today. They are not really doing any more country studies. This was a one time event that McKinsey probably will never do again nor will probably any private sector institution do again. And that's the reason every time I speak at the World Bank I say you guys have got to pick this up. You are the right institution; you have the resources; you have the access and you have the charter so you really need to do this.
SCHULZ: I hope Paul Wolfowitz will be giving you a call.
LEWIS: I got Jessica Einhorn, the Dean of SAIS, who succeeded Paul as the Dean of SAIS, to send him a copy of my book, so I hope he does pay attention to it.
SCHULZ: Excellent. Well I think he is the kind of person who might be receptive to these ideas. And I do think they are absolutely critical. I want to thank you for talking to us today.
LEWIS: Thank you.
