What follows is an application of the guidelines within the article, "the science of scientific writing".
I happened to have a random article handy. It describes Ricardo, software which integrates R and Hadoop. Apologies to the authors.
Many of today's enterprises collect data at the most detailed level possible, thereby creating data repositories ranging from terabytes to petabytes in size. The knowledge buried in these enormous datasets is invaluable for understanding and boosting business performance. The ability to apply sophisticated statistical analysis methods to this data can provide a significant competitive edge in the marketplace. For example, internet companies such as Amazon or Netflix provide personalized recommendations of products to their customers, incorporating information about individual preferences. These recommendations increase customer satisfaction and thus play an important role in building, maintaining, and expanding a loyal customer base. Similarly, applications like internet search and ranking, fraud detection, risk assessment, microtargeting, and ad placement gain significantly from fine-grained analytics at the level of individual entities. This paper is about the development of industrial-strength systems that support advanced statistical analysis over huge amounts of data.
Here's my rehash.

The distance between subject and verb should be short
Certain parts of sentences and paragraphs have stress points; these stress points should be at the end, not at the front. Introducing new information at the front is anti-climactic and distracting. Like telling a joke, the punchline is at the end...
The part of the sentence linking back to the previous one should be at the start of the sentence. Say, there is a sentence with parts A and B, and another sentence with parts C and A. Then the structure of the combined sentences should be: A:B, A:C or B:A, A:C, and not A:B, C:A. I think the second pattern is preferred to the first. Reminds me of lego pieces.
Why are mathematical types susceptible to incomprehensible writing? I'll hazard a guess that the thought process goes along something like this. There are a series of causal statements: If A then B, If B then C, if C then D. Then writing down these relationships we can infer that if A then D. It breaks convention of logical thought to reverse the causal statement (and of course it's not necessarilty true): then B if A, then C if B, then D if C.
We citizens of modern complex societies are an anomaly of history.
Complex societies tend to be 'nearly decomposable systems' (Simon 1965: 70); they are partly built up of social units that are potentially stable and independent.
As societies develop, ineuqality descreases and heteregeneity increases (McGuire 1983: 110-11).
Insufficient response to circumstances
Fundamental limitations of social, politcal, and economic systems prevent an propriate response to circumstances, and this makes collapse inevitable (Betty Meggers 1954 on environmental limitations to civilization, and Elman Service 1960, 1975 on the law of evolutionary potential).
The more specialized and adapted a form in a given evolutionary stage, the smaller its potential for passing to the next stage.
Roy Rappoport (1997) and Kent Flannery (1972) - complex societities are closely interlinked; self-sufficiency and autonomy of local systems are reduced as specialization increases. In less complex settings, a society is cushioned against disruptions by less specialization. Civilisation may be maladaptive.
Phillips (1979) - reminiscent of Gibbon's view on the Roman Empire. As the state becomes more efficient there is less flexibility in its resource allocation, reducing the ability to handle crises.
Shephard Clough - resources are diverted to art and knowledge instead of from investment in capital.
Understanding Collapse: The Marginal Productivity of Sociopolitical Change
It is provided in the essence of things that from any fruition of success, no matter what, shall come forth something to make a greater struggle necessary. Walt Whitman
Looks like the corollory to failure breeds success to me.
societies are problem-solving organizations
sociopolitical systems require energy for maintenance
costs increase with complexity
investment in sociopolical complexity as a problem-solving response often reaches a point of declining marginal returns
The chapter contains graphs of declining marginal productivity in agriculture, research and development, and the health system.
With increasing time spent in education and greater specialization, the learning that occurs yields decreased general benefits for greater costs.
D. Price (1963:102-3) - educating more scientists causes those of average ability to increase in number faster than those who are most productive.
Sociopolitical control and specialization
Control and specialization are the very essence of a complex society. The reasons why investment in complexity yields a declining marginal return are:
(a) increasing size of bureacracies;
(b) increasing specialization of bureacracies;
(c) the cumulative nature of organizational solutions;
(d) increasing taxation;
(e) increasing costs of legitimizing activities; and
(f) increasing costs of internal control and external defense.
Tainter presents 3 case studies of complexity and marginal returns: the Roman Empire, Mayans and the Chacoan society of northwestern New Mexico (6 periods spanning 400 AD to 1200 AD).
Adams, R. E. W. estimated the population of Maya decreased from 3,000,000 to 450,000 over a 75 year period. Collapse was swift. In 790 AD, 19 centers erected monuments compared to 3 centers in 830 AD.
These are my notes on Chapter 18 of Woolridge (2002).
With randomized treatment, the average treatment effect E[y1 - y0] is the same as the treatment on the treated E[y1 - y0|w =1]. Intuition: because treatment is random, the sample of treated people reflect the population.
The Mean Independence assumption (E[y|w] = E[y]):
E[y0|w] = E[y0]
E[y1|w] = E[y1]
The means of y are independent of w. These hold when treatment is independent of who benefits; it's random. This is slightly confusing because y0 is also the counterfactual that doesn't exist for those that are treated.
If y1 - y0 is not mean independent of w, ATT and ATE generally differ.
From the weaker assumption of just E[y0|w] = E[y0] , a difference in means will estimate the Average Treatment on the Treated. i.e. E[y0|w=1] = E[y0|w=0].
Those that aren't treated would have had the same outcome w0 as those there were treated. Dubious as y0 is likely to influence w.
Ignorability of Treatment (Propensity Score Matching)
When w and (y0, y1) are allowed to correlated we need an assumption in order to identify treatment effects.
Assumption 1: w and (y0, y1) are independent, conditional on x.
Assumption 2, conditional mean independence, also known as selection on observables:
E[y0|w, x] = E[y0|x] and E[y1|w, x] = E[y1|x]
Even though w and (y0, y1) may be correlated, they are uncorrelated once we partial out x.
Under the second assumption, conditional mean independence, ATE and ATT conditional on x (ATE(x) and ATT(x)) are identical.
I've been banging my head up against understanding monads in Haskell for a while, but I'm now delighted to have finally cracked the puzzle. There are a myriad of tutorials and I find it highly unusual that the guides do not all point to You Could Have Invented Monads as to go-to tutorial. Where Dan Piponi (sigfpe) succeeds when others have failed is through demonstrating Monads by example before formalising the definition. The other key to its success is that exercises are provided along with the examples to make the concepts concrete.
There are however some gaps, which are not problematic for the reader, until you actually sit down to do the exercises. This blog post is intended as commentary should you get stuck working through that tutorial. I have included some documentation on monads which should help you avoid the red herrings that are thrown into introductory tutorials.
I will start by repeating the errors of those who have gone before me (explaining Monads by providing a formal definition) by introducing generalized notation. The key to learning monads is interpreting type signatures.
f and g are functions that map from some type to the same type, like Int to Int.
f, g :: a -> a
f', g' are analogues to f and g with the addition the the result is chucked into a container. The examples of containers in the tutorial are tuples (Integer, String), lists [a], and states (StdGen, a StdGen).
f', g' :: a -> m b
Next up is bind. bind f' combines two containers (m a and m b). So bind by itself combines two functions of type (a -> m b), f' and g'. This is where the type signatures are useful. The inputs are actually (a -> m b) and (m a), not (a -> m b) and (a -> m b). What gives? Well, bind combines f' and g' a. Either g' requires an argument, therefore giving a container with a value as the output, or we just add a container with a value as the input. The type signature shows the output of bind is also a container with a value in it.
bind f' :: m a -> m b
=> bind :: (a -> m b) -> m a -> m b
note: bind has been defined right associative in the tutorial so if's f (g x) or h (f (g x)), or bind h' . bind f' g' x.
unit is the identity analogue where f . id = id and id . f = id.
unit :: a - > m a
lift niftily converts a regular function with type (a -> a) to a monad (a -> m b).
lift f :: a -> m b
=> lift :: (a -> a) -> a -> m b
Having defined a bind function that connects a (a -> m b) function to a container/monad (m b), wouldn't another useful function be one that connects two (a -> m b) functions?
Enter the compose function (Thompson).
>@> :: (a -> m b) -> (b -> m c) -> (a -> m c)
The monad compose function is introduced during formal definitions of monads as it is easier to show associativity with this function, rather than bind. Associativity is one of the requirements to qualify as a monad.
Next, let's define a function that connects two containers.
It is a monadic sequencing operator which throws away the unpacked value of type a before executing the action of type m b (Yet Another Monad Tutorial - part 3).
>> :: (m a) -> (m b) -> (m b)
Allows for containers to be combined and throws away the inputs.
The three exercises
There are only three exercises for each Monad in the tutorial.
1) define bind. It has the type signature define earlier.
1b) define an operator * such that unit * f' = f' * unit = f'
f' :: a -> m b
also, the operator * is an infix equivalent of the function bind.
2) define unit. 2b) define lift as lift f = unit . f
3) show that lift f * lift g = lift (f . g)
note: equivalent to f'' * g'' where f'' = lift f and g'' = lift g
And that's it. Answers to follow in subsequent posts.
For the record, I tried Real World Haskell, Learn You a Haskell, and Write Yourself a Scheme. I also watched Brian Beckman's Don't Fear the Monad, which made sense at the time, but had forgotten soon after watching. In relation to other useful references, I found this to be a good companion piece that provides an intuitive explanation. Mike Vanier's series (I read 1, 2 and 3) is also useful too, but probably only after grasping most of it.
Why are Monads confusing? Because it is a very abstract concept that is best explained in a non-abstract way. Aside from that, notation and partial function application, mainly. I also think that it should be called containers for side effects, or something like that.
Trendspotting. Published in 1957, Whyte's is still an accurate summation of a large part of the present.
Whyte's Organization Man appears to be strong influence on the views of Venkatesh, of the Ribbon Farm blog. He discusses the book in 3 parts: part 1, part 2, and 3.
These are my notes and quotes from the book.
Because they are the largest single group, the corporation-bound seniors are the most visible manifestation of their generation's values... Whatever their many differences, in one great respect they are all of a piece: more than any generation in memory, theirs will be a generation of bureaucrats.
The last thing students can be accused of now is dangerous discussion; they are not interested in the kind of big questions that stimulate heresy and whatever the subject - the corporation, govenrment, religion - sutdents grow restive if the talk tarries on the philosophical.
Perhaps contemporaryism would be a better word than conservatism to describe their posture. The present, more than the past, is thier model; while they share the characteristics American faith in the future also, they see it as more of the same... The big questions are all settled; we know the direction, and while many minor details remain to be cleared up, we can be pretty sure of enjoying a wonderful upward rise.
Commentary on the younger generation of students has now become reality.
More than before, there is tremendous interest in techniques. Having no quarrel with society, they prefer to table the subject of ends and concentrate instead on means. Not what or why but how interests them...once they have equated the common wealth with organization... they will let the organization worry about goals. "These men do not question the system", an economics professor says of them, approvingly. "They want to get in there and lubricate and make them run better. They will be the technicians of the society, not innovators."
The attitude of men majoring in social science is particularly revealing on this score. Not so very long ago, the younger social scientist was apt to see his descipline as a vehicle for protest about society as well as the study of it. The seniors that set the fashion for him were frequently angry men...[References Robert and Helen Lynd's Middletown as an example of big studies in the twenties and thirties]
Reflecting the growing reconciliation with middle-class values that has affected all types of intellectuals, they are turning more and more to an interest in methodology, particularly the techniques of measurement. Older social scientists who have doen studies on broad social problems find that the younger men are comparatively unintested in the prolbems themselves. When discussion period comes, the questions the younger men ask are on the technical points; not the what, or why, but the how.
The urge to be a technician, a collaborate, shows most markedly in the kind of jobs seniors prefer. They want to work for somebody else.
In Chapter 17, the Bureaucratization of the Scientist, Whyte notes the shift towards group work as indicated by the number of coauthors per published journal article. This manifestation is rampant in medicine, and the public health disciplines, though it is not necessary for public health. It can be argued that the amount of funding required necessitates that teams work on certain projects.
Chapter 21, The Transients. Suburbia illuminates the rootlessness of the organization man.
The man who leaves home is not the exception in American society but the key to it... And for all college men, incidentally, the higher the grades, the more likely they are to move.
Could almost be a description of the present.
But perhaps the most important reason the transients can't go home is that they won't find it there if they do. It is not just the physical changes... As the young transients have left town, their opoosite nubers from other towns have come in, and in many American communities there has been wholesale displacement from positions of power of the names that once "meant" something.
Once people liked to think, at least, they were in control of their destinees, but few of the younger organization people cherish such notions. Most see themselves as objects more acted upon than acting - and their future, therefore, determined as much by the system as themselves.
To a large extent, to my way of thinking, the trends observed by Whyte are still evolving through Western society. The most convincing explanation for underlying trend is due to the replacement of religion by science (Jordan Peterson). In addition to the increase in conformity, collobaration and techniques, the culture of science pervades education and business. Even the characterisation of science is represented pop culture now. It seems to tie in with nihilism and the absence of belief, leading to conflict and war, speculated by Nietsche. There seems to be a general vacuum of morality and meaning.
If there are parallels between the booming 1920s and the 2000s, perhaps this is the lull before the storm of WWII. See Kyle Bass, researchers from the IMF, and the complex systems institute (e.g. , , ), who are predicting increasing world conflict in the foreseeable future.
Sometimes I think it'd be nice to be able to learn without paying for my mistakes. Back in 2007/2008 I bought some shares in NSX, a second tier stock exchange, which traded taxi licenses or something like that. I don't think it was profitable, liquid or had any particular growth prospects. But I was convinced that it was a decent pick because it was a monopoly and the ASX, which had recently merged with the SFE (the futures exchange), had been profitable in the lead-up to the great financial crisis.
Fast forward to 2013. At this point in time, I'm still keen on owning companies which are monopolies so I take a small position in Microsoft reasoning that it had been under-performing for a decade or so with sideways movements in the share price, and decent profitability. I jumped the gun and sold with a modest price increase, as all stocks gained in 2013. The catalyst for the larger price movement was the departure of Ballmer who had erred in lagging in mobile technology, and who appears to have been lacking the requisite vision to steer the ship away from obselescence.
The new CEO has been decisive. He announced staff cuts and agreed to ship the office software on Apple products. In short, the optionality in MSFT's share price is gone.
A bit later, I'm scouring Google Finance and looking for cheap stocks when I come across TFS Corporation. With a P/E of around 5, I'm convinced it's a value trap because it's so cheap. I watch it loosely and jump in when the price takes off.
Another digression: as a novice investor I thought that buying stocks on the decline was better as they were cheap; I was buying low, hoping to sell high. Great in theory, but extremely difficult to time as it is difficult to pick the bottom until after the fact. Hence the phrase, don't catch a falling knife. I know now, but don't remember the source, that a rising stock price is a good sign. The caveat is that it's hard to tell if it's overpriced. Go with your friend, the trend.
Back to TFC. It's the monopoly I've been looking for, my conviction monopoly. It is a forestry company which sells sandalwood products. Indian sandalwood is on the preservation list so forestry is illegal. This, combined with increasing demand, has presumably sent the commodity price upwards.
TFS is the sole commercial producer of Sandalwood trees. Management's incentives are aligned with the founder having a significant percentage of shares. The founder left a private practice law firm to grow and sell trees, which suggests that he had a vision for the company which outweighed the opportunity cost of being a decently paid lawyer.
The company has been in existence for well over a decade, and has improved the survival rate (or is it extraction rate) of its trees. This confirms the suspected IP edge the company would have over any prospective entrants, the barrier to entry.
As a perfect storm for why this information hasn't been priced into the stock is the disaster that was Timbercorp and the forestry schemes that failed in the 2000s. These schemes allowed individuals to invest in forestry, agribusiness products with a tax advantage. Timbercorp went bankrupt in 2009, partially contributed by the government changing the taxation of these schemes. TFC was tarnished with a broad brush, having also offered these products, but not having mismanaged its financial affairs. It also had a market cap of less than $200m.
TFS increased production of sandalwood from late 2013. It then signed a JV with a pharmaceutical company to provide sandalwood to create treatments. A director recently bought a sizeable ~$170k AUD (at ~$1.70) amount of shares with the family trust.
Broker reports, which are publicly available and linked to from the website, indicate that production volumes are forecast to rise rapidly over the next 3-5 years. As Mr. Market tends to only believe only what he sees, I don't think it is priced in, and if anything, I think the share price will overshoot as volumes and earnings increase. I've been buying in with each successive price jump, and it looks to be taking a breather before the next increase. Time to get onboard. I can see the share price doubling or tripling from here. Beyond that I can conceivable see this niche monopoly company consolidating into a steady but less exciting cash cow. Comments welcome.
[BH: The day after I wrote the draft for this post, 14th August 2014, TFC jumped from $1.80 to $2.05 over two days. The catalyst was another set of presentation slides, which didn't really contain any news. After stewing on how amateurish this post is, with its lack of financials commentary, and whether the eclectic mix of posts is an issue, this post was published on 8 September. Other good news since then is that it appears from a corporate governance perspective that the company has been on the improve, with another director resignation (same one as mentioned above). This follows a resignation earlier in the year (Gilchrist I think, who in all likelihood was playing purely a marketing role). The (large) positions held by these individuals is a positive. ]
This is a dense book, with interesting thoughts throughout. It's not often a book has 5 stars for average review on Amazon and this book doesn't disappoint. One notable quirk is that the author is a self-described druid, not a journalist, scientist or writer. He also comments in a conversation with Chris Martenson, on his Peak Prosperity podcast, that he earnt his beard and ponytail by living on a commune for some period of time!
According to Greer, Ernst Schumacher, born in Bonn, 1911, layed the foundation for incorporating energy into economics.
Renewable resources, he proposed, form the equivalent of income in the primary economy, while nonreneweable resources are the equivelent of capital...
He argued that energy cannot be treated as one commity among many without reducing economcis to gibberish, because energy is the gateway resource that gives access to all other resources.
Greer goes on to list a few ecologically sane economists since Schumacher: Nicholas Georgescu-Roegen, Kenneth Boulding, Herman Daly and Robert Costanza. He somewhat pre-emptively points out Adam Smith did not have a degree in economics.
Economics suffers from premature mathematization - paraphrasing here, economics involves so many variables taht the only way to control them all is to impose conditions so arbirary that the results have only the most distant relation to the real world. Greer concludes the only logical way out of the trap is to concentrate on economic history. note a set of conditions in the past that consistently lead to a common result, e.g. house bubble (p17).
Have you noticed that the guys who run macroeconomics based hedge funds are all trained in the humanities and have a keen interest in history? For example, Kyle Bass predicting that there may be war on the horizon.
Social critics have commented on the ease with which neoclassical economics ignores the interface between economic wealth and power... This is a pervasive problem in most human socities, and it's worth noting that those socities that survive over the long term tend to be the ones that work out ways to keep too much wealth from piling up uselessly in the hands of those with more power than others.
.. those nations that got through the last Great Depression intact did so by imposing sensisble checks and balances on concentrated wealth.
I recall a marginal income tax rates of 98% at some point. Need to find a reference here. And isn't it at this point in time which anti-trust law is enacted? There was a large correction towards protecting the ordinary in society after the destruction wrought by the Great Depression.
When wealth is widely distributed, more of it circulates in the productive economy of wages and consumer purchases; when wealth is concentrated in the hands of a few, more of it moves into the investment economy where the well-to-do keep thie wealth and the buildup of capital in the investment economy is one of the necessary preconditions for a speculative binge (p20).
This is echoed by Nick Hanauer, the friend of Bezos, who manufactures pillows and says that he only needs one pillow despite his wealth .
There's a rich irony here, in that the market economy portrayed by textbooks.. is a form of commons, and a great many people who claim to be advocates of free market have spent years arguing that commons should be eliminated wholesale in favor of private ownership.
All common systems, as Garrett Hardin pointed out in his famous essay, have to be managed in ways that prevent individuals from exploiting the commons for their own private benefit; otherwise they fail.
Paraphrasing again, Elinor Olstrom demonstrated that it's entirely possible to manage a commons so that Hardin's Tragedy of the Commons doesn't happen (p27).
Energy, as E.F. Schumacher pointed out, is not simply one commodity among others; it is the ur-commodity, the foundation for all economic activity (p30).
a world that has nearly seven billion people on it anda dwindling supply of fossial fuels can do without the assumption that putting people out of work and replacing them with machines by fossil fuels is hte way to prosperity (p39).
Liebig's law of the minimum: production is limited by the scarcest necessary resource
Around 75 cents of every dollar circulating was provided by natural processes rather than human labour - Costanza, Robert, p54.
The difference between the supply-limited goods of the primary and secondary economy and the demand-limited goods of the tertiary economy, among other things, a difference between kinds of feedback.... in a market economy all secondary goods are subject to negative feedback. ... Negative feedback loops of a very similar kind control the production of primary goods by the Earth's natural systems...It's when we get to the tertiary economy of financial goods that things change because the feedback loops governing tertiary goods are not negative but positive (p69).
Eventually the supply of buyers runs out, because everyone who is willing to plunge into the bubble has already done so. ...prices began to sink, and once again positive feedback came into play as the adothermostat shifted from heating an overheated house to cooling an overchilled one. p71
financial investments don't suffer from rising energy costs so individuals move their investments from the productive economy of goods and services to the paper economy of finance. Ironically, this is happening just as perpetually expanding money supply driven by mass borrowing at interest has become an anachronism unsuited to the new economic reality of energy contraction. p75
The Mayans responded to their agricultural criss by accelerating building programs, p.80.
Vico attempts to document the course nations run with classical Greece and Rome.
three-century-long beinge with finite supplies of cheap abundant energy spawned a second bubble of money and finance, abstract representations of wealth, p105.
stagflation from oil shocks in 1970s. Rising prices and wages struggling to keep pace with diminished economic activity.
second law of thermodynamics: energy moves from higher to lower concentrations.
notes the distinction between quantity of energy and concentration of energy, where the latter is more important. Diffuse energy - it doesn't take concentrated energy to heat a tank full of water. It can be done efficiently by diffuse energy sources such as sunlight, p138.
the amount of work you get out of an energy source depends, not on the amount of energy contained by the source, but on the difference in energy concentration between the energy source and the environment.
Points out that Thomas Friedman's Hot, Flat and Crowded is correct in stating that we're facing global wierding, a worsening of conditions, unexpected and disruptive weather events.

The ongoing depletion of natural resources is a case of a potential tragedy of the commons. Individuals or companies have an interest in using up the finite resource, be it petrol or fish in the ocean, but by doing so will damage the collective group. The uncertainty involved in the trade-off between technological innovation and resource depletion is complex. For example, Richard Heinberg writes in 2004 about unconventional petroleum resources, suggesting that they are too costly to extract. Forward 10 years later, and we have a boom in shale oil production . Even with the development in shale oil, he still believes its impact is overstated and will be short-lived .
Unconventional petroleum resources -- so-called "heavy oil," "oil sands," and "shale oil" -- are plentiful but extremely costly to extract and process, a fact that no technical innovation is likely to change much

 Peak Prosperity Podcast with Chris Martenson
Powerdown - Richard Heinberg
Heinberg provides evidence our endless supply of non-renewable resources are disappearing fast. He outlines three ways of handling the pending crisis: competition for the remaining resources, powerdown - cooperation, conservation and sharing, and wishful thinking.
Charlton provides some good insights into the Australian macroeconomy, but probably covers too much territory to summarize succinctly.Topics include debt, central banking, housing, manufacturing. He summarizes the economy as productivity, jobs and equality. The premise of the book is that the labour government was responsible for a series of reforms in the 1980s which was the basis for the economic boom in the 90s and onwards. Charlton suggests the triumph of the Howard Government is taking credit for the results.
The other point that sticks out is Charlton's thoughts that Latham threw the election by choosing to compete with the Liberal government about budget surpluses, a furphy for the reason that international debt markets mean that surpluses are not a real (imminent) issue.
Charlton stands out for having a doctorate from Oxford and being Rudd's economic advisor at around 30 years old. Presuming that an advisor to the Prime Minister would remain in politics, it surprising to see that he went on to head the liquor division of Coles after Labour lost office.
The essential feature of hte Australian economy has always been that we have a huge continent full of natural resources and a tiny population among which to share its bounty.
Dutch Disease arsies because high prices for our commodity exports drive up the value of Austrlian money, which then makes our manufactured goods more expensive relative to those produeced by foreigners.
The post-war commodity boom made the AUD one of the world's strongest currencies. Advantages in agriculture and mining lead to manufacturing weakenss. Charlton goes on to say that early leaders recognised the need to diversify the economy. Enter the second Prime Minister, Alfred Deakin, 'No nation ever claimed greatness which relied upon primary industries alone'.
This meant propping up manufacturing with high tariff walls to protect Australian- made goods from the competition of imported substitutes.
Charlton summarizes: farming and mining supports manufacturing businesses through tariffs and is also passed on to workers through a centralized wage-fixing system.
In 1984 Mancur Olson wrote a paper arguing for the lowering of tariffs on manufacturing in Australia. He argued that Australia was in a favourable position to obtain increases in real income from increasing manufacturing, citing an abundance of raw materials and a well educated and technically sophisticated population. He advocated freer trade to increase gains to Australia, larger than what would be expected from the theory of comparative advantage. He writes in the summary:
... the level of protection is very important among small economies as an indication of their ability to export. There is a striking pattern:
if countries have high levels of protection on manufacturing, without a single exception, they export very little of their manufactures. Australia is the second most protectionist on manufactures of the devloped countries, and Australia exports only about 7.5 per cent of its manufactured output.
Olson suggested a test of his theory of the logic of collective action by looking at the manufacturing and degree of protection in small and medium sized countries.
.. the patterns of trade in manufactured goods provide better insights into the efficiency of the institutions and policies of a country than do pattern of trade in primary products, because the dependence of manufactures on teh endowments of natural resources is not as strong as in the case of primary products.
The intuition is that these countries are the ones where protection (a collective action) will have its greatest impact. That is, the mileage of barriers, as determined by the size of the jurisdictions, should be of greater significance than the height of the barriers. He touched on evidence for distributional coalitions acting as a drag on the economy: Low growth is expected in long-stable countries like the UK due to the influence of organizations for collective action. In contrast, Japan, Germany and Italy experienced rapid growth from the destruction of these organizations after world war 2. Olsen also suggested that the USA has similar historical trends, where the Northeast and Eastern Middlewest are decline, whereas the frontier areas in the West and recently turbulent South are doing better.
The results presented show a strong correlation between tariffs (1976) and 1973 percentage of manufactures exported (value of manufactured exports / value of manufactured output). Denmark (42.5%), Sweden (37.5%), and Austria (32.5%) are offered as counterexamples with low tariffs and large percentage of manufactures exported.
In summary, Olson discounts the idea that protectionism is beneficial in the early stages of infant industries and interprets the abundance of small high exporting countries with low tariffs and the failure of medium sized protecionist coutnries to attain impressive outputs of manufaturing to indicate that protection of manufactures does not lead to increasing manufacturing output of a country in the long run.
The Decline of Manufacturing in Australia
The manufacturing industry in Australia has been in decline for a protracted period of time, and has coincided with the growth of the services industry. In recent years, automakers Toyota and Ford have announced job cuts as well as the inevitable closure and relocation of plants to other countries, such as Thailand. The high labour costs arising from Australia's centralised wage setting institutions and the historically high Australian dollar no doubt played a large role in these changes. The strength of the Australian economy has been driven by a large one in a lifetime resources boom, where China now comprises 25% of Australia's exports.
Three decades have passed since Mancur Olson advocated that Australia decrease its manufacturing tariffs in order for Australia to develop internationally competitive manufacturing and consequently increase manufacturing output. What has happened since then, is that the tariffs have been reduced , albeit to differing degrees depending on product. Amazingly, in line with Olson's prediction, the percentage of exports to sales has risen to 35% .
Despite this, manufacturing has decilned as a share of all industries due to the growth of other industries and the contraction of manufacturing itself. Reducing tariffs appears to have improved, or coincided with the improvement of, the ratio of exports to total manufacturing but manufacturing itself has become less important over time. Is there a trade-off between size of manufacturing with the percentage of manufacturing exported?
