Dont have all too much to say about Freakonomics, I enjoyed it but wasn't as interested as I was while reading Sachs, Easterly et al. While it does encourage me to apply economic analysis to questions in my everyday life, I was already aware that economics can explain many interesting phenomena. If anything, it has once again emphasized my need to take econometrics and stats.
Hello once again.
Primarily, I’d like to try to make the point that I don’t think Easterly and Sachs are contradicting each other too thoroughly. Maybe I’m just interpreting them both as I see fit because I liked them both, but I think their positions on aid and debt could be compatible. Concerning foreign debt: Easterly includes an entire chapter on the failures of debt forgiveness. Nevertheless, he ends his chapter with an explanation of how debt forgiveness can work. “A debt relief program could make sense if it meets two conditions: 1) it is granted where there has been a proven change from an irresponsible government to a government with good policies; 2) it is a once-for-all measure that will never be repeated.” Although the scale of debt relief may differ under the two economists, Sachs’ successful uses of debt forgiveness seem at least to fulfill condition 1. His arguments for forgiving
Concerning Foreign Aid: I was never under the impression that Easterly was against foreign aid. It just seems that he claimed that past aid was misdirected, and as a result ineffectual. Sachs mentions many forms of aid through technology sharing which Easterly would love. His sections on India’s IT boom, Asia’s Green Revolution and Bangladesh leapfrogging to cell-phones are all examples of developing the technology base and creating the environment for matches which Easterly advocates as needed to escape poverty traps.
OK, first let's dispense with the pleasantries. Loved the book, wanted more, etc. With regard to the ideas found in the book, I would say that if there was a "unifying theme" it was that economic tools can be used in interesting and insightful ways, however, this book removed the economic analyses to such a large degree that one couldn't really check the underpinnings for mistakes. That is not to say that I assume that there are any, but what about another respectable economist who comes to precisely opposite conclusions, having claimed to have controlled for roughly similar variables? It seems like this book could have fruitfully given a way to distinguish between good economics and bad economics. It seems as though there are so many "well-respected" economists out there, and yet it's almost impossible for most to tell whether or not they overstep their "good economist" capacity on a regular level (Paul Krugman, perhaps?). In any event, I think the strategies are well-described in the book, but they seem anecdotal more than formulaic; as the authors note, "It should be said that regression analysis is more art than science" (163). If that's the way we should look at it, what aesthetic philosophy can we use to separate good regression analysis from the bad? Though the thought is all the more horrifying if politicians are involved, it seems as though a regression could claim to "prove" anything if its purveyor is previously "well-regarded" by other economists who have come to opposite conclusions.
Personally, I thoroughly enjoyed Sachs' book; it was a good read, it was optimistic, it cited historical examples, it listed directly applicable goals and frameworks that could be applied in the case of all countries, and, perhaps most importantly, it did not resort to over-simplification. Though this tendency to simplify may be the economist's main gripe with politicians, it still seems apparent in economic books which too narrowly examine the relationships of certain variables and their impact on the economy. Sachs points out that the model is far too multi-faceted to simplify as such (which is in line with common sense); indeed, a clinician's outlook on development economics is necessary to correctly diagnose a sick patient and prescribe the proper treatment.
Looks like Tim Harford (a Financial Times columnist, author of The Undercover Economist) just read Easterly too, but forgot to cite his sources. Of course, he gives much more focus to the political angle, one which highly coincides with my own tastes.
Similarly to Chris, I had a complete change in opinion of Easterly once I started reading section III. Although I thought it was interesting to put statistics to the many development policy failures I was slightly familiar with, I felt that part II gave short shrift to these “panaceas.”
The best example of this tension between parts II and III that I found was his discussion of Solow. Since I’ve had several classes which turned to the Solow growth model as a saving grace for the developed world I was shocked to have Easterly reject that in part II. The complaint that less developed nations have barely grown at all rather than converge towards the more developed nations seems to be quite damning evidence against the classical Solow model. Furthermore, Easterly attacks the idea that nations must merely overcome a transition period of increased investment to achieve the optimal level of current and future consumption. While his claims seem to be valid, I felt he abandoned the idea of investment too quickly. This, however, turned out to be planned once I began reading chapter 8. To the best of my understanding, proposals he makes for increasing returns would completely change the shape of the Solow model. (This is something I’d really like to discuss tomorrow) As a result, the divergence which empirical evidence suggests can be more readily explained. Now one enters a world where a corporation would receive greater returns from investment in labor or capital in the more developed world. However, the shapes which I was left with for the model still demand investment. Although there is less of a transition period, per se, foreign aid and world bank investment would actually seem to help developing nations even more in this modified model than in the classical Solow model. Increasing marginal returns would imply that new investment in education or infratstructure would actually make future investments even more lucrative, possibly moving a nation from a vicious to a virtuous cycle.
Several examples can be found where Easterly’s models from section III could be applied to encourage further use of his “failed panaceas.” Couldn’t loans and investment aid be focused on creating complementary technologies such as roads and computer systems? Why does Easterly abandon Mankiw’s analysis of secondary education as a determinant of growth when his own model would imply that exactly that kind of education could encourage the increasing returns of matching and leaking? Upon close analysis, I found that Easterly’s “failed panaceas,” might be medicines applied incorrectly or to allergic patients. If corruption and poor policies can be addressed, I see no reason why capital investment, education, debt forgiveness and adjustment loans couldn’t be used to move developing nations into virtuous cycles.
Ok, I'd like to discuss the Solow Growth Model, since I don't know it as well as some of the more econ-proficient, so please correct me if I have my facts wrong. Thanks.
How lamentable that I had not found this before reading Hayek's Road to Serfdom! It was still a good read though.
Of all of the diverse topics that Krugman touches on, I found that his discussion of free trade and protectionism was the most interesting. Throughout the chapter there were interesting tid-bits that I hadn’t really thought about in past musings on free trade.
1)
2) Even more interesting to me were Krugman’s claims that protectionism might not be as bad as this ideology would have us believe. With the amount of time and energy spent proselytizing the benefits of free-trade, I was astounded to discover that US import restrictions only impose costs on world efficiency equal to one quarter of one percent of US GDP. Arguments that claim that protectionism could be an inherently good thing such as strategic trade policy theory seem to further weaken the hysteria surrounding the need for free trade. Although I still don’t believe free trade’s positives should be ignored, I thought it was interesting to be exposed to some argument suggesting that there might be creative views to look at the positives and negatives associated with opening markets.
Throughout this chapter, I constantly thought about what trade protection really is. Through some of my work on international agriculture I have started to naturally equate US and EU ag subsidies with third world tariffs and quotas. What is the fundamental difference between subsidizing producers on their exports to artificially lower export prices and taxing imports to artificially raise import prices? It seems that this argument could be further expanded to include almost any type of government expenditure. Doesn’t health care, education, non-corrupt property protection and law enforcement all reduce the cost of production for individuals and corporations? Do these policies not offer an unfair, government sponsored, advantage to some nations over others? It seems that the best way to argue for these programs in an economic light would be to use variations of Krugman’s ideas of strategic trade policy. I need to further explore this but maybe comments to this post and discussion tomorrow will help me flesh it out.
The first thing about The Age of Diminished Expectations that struck me is the irony in Krugman's discussion of the diminished expectations of a society so caught up in the American Dream, and the pursuit thereof, that many of its members fall victim to the "irrational exuberance" Krugman would later refer to in The Great Unraveling. The key delineation is that the diminished expectations Krugman discusses in this volume are popular expectations about the management and overall performance of an economy; Krugman paints a gloomy picture about the ability of fiscal/monetary policy to productively improve economic conditions, especially with relation to social issues. The reader might be led to believe that only free markets, independent of arbitrary government intervention, can resolve the issue, but that such a solution requires a business cycle that the socially-minded among us would not accept. As such, Krugman illustrates, American expectations have been tempered to expect and consent to government mismanagement, so long as it steers the economy clear of disaster. If such an assessment of the American mentality is true, what implications does this attitude have for American economic philosophy, especially considering a large part of America's historical success has been thanks to the encouragement of the American Dream.
Since I feel pretty similiarly to Sam and wanted to touch on the environmental stuff from the book, I thought I'd build off what he's said.
First off, general impressions about the book: I think Blinder would be useful to thrust into the arms of those who are less knowledgeable about economic topics. His writing style is very accessible and one doesn’t get the feeling that he is making presumptuous self-righteous editorializing. This may explain why Sam wanted to have the chapter to hand to loopy environmentalists. I also found the discussion on monetarism, rational expectations and supply side economics , while possibly overly dismissive, a good history lesson. Nevertheless, I have to agree with Sam that this may have been a little too simplistic for us at this point. More rigorous economics or more radical departures from thought we’ve been reading might be interesting to dive into at this point. Oh well.
About the environmental section: I thought Blinder did an excellent job of characterizing environmentalism and how to best solve environmental issues. I’m happy to say that most respected environmentalists that I know of have moved towards his solutions. For me as a philosopher, the dismissal of rights does become slightly problematic. If one doesn’t look at inherent rights and value, arguments for making decisions outside the market for the benefit of non-human entities becomes difficult. Dealing with questions of pollution as questions of “more or less” rather than “yes or no” does create problems with my sympathies with deep ecology as a philosopher. Nevertheless, when I don my cap as an economist, I recognize that I am evaluated transactions between humans and would gladly work to increase the efficiency of this system.
It is here that I think Blinder and the economists of his time made large contributions. His discussion of sulfur dioxide regulation was incredibly interesting because it was the terrible inefficiencies of sulfur regulation which led to the huge successes of sulfur pollution control as a large scale test of cap and trade policy. In fact, that success seems to have convinced most environmentalists that I have studied under that there is a great deal to be said for market based pollution control. Even in working for Greenpeace in
There are some problems with market solutions, however, that I think Blinder misses and policy makers should be aware of. Most significantly I was troubled by the lack of discussion of environmental justice. As Blinder knows, markets may create the most efficient systems but they in no means guarantee proper distribution. Cap and trade systems have been feared by environmental advocates, especially those working as social advocates in low income areas, due to the fear of pollution bubbles. If air rights are less valued in a low income area than in
Another point I would like to make is specific to environmentalist support/dissent on market systems of the Bush administration. Many people attack environmentalists for their opposition to these “efficient” solutions. However, if one looks carefully, the biggest complaints are usually that any shifts the current administration makes towards market regulation also includes increases in the absolute amount of pollution allowed under regulatory schemes. Total permits may allow more tons of a toxic than current regulation allows of the industry. I think many environmentalists would jump at the chance to create a true polluter pays system where every permit is sold and there are no “free” permits or tax exemptions. As blinder notes, however, this would not be acceptable to the industry.
It was an interesting juxtaposition to read Blinder immediately after Barro, partially because Blinder wrote Hard Heads, Soft Hearts a few years before Barro wrote Getting It Right, but more because of the fact that both (like most academics, I would imagine) thinly veil their political tendencies behind a façade of “objective economics” or universally appealing principles. Blinder inserts his political leaning (Democratic) in his presumptively desirable principles of equity and efficiency; by claiming that the poor are “inherently needier than the rich,” Blinder skips past his assumptions of what constitutes need and how resources ought to be distributed in the first place. Sustenance, clothing and shelter may be three things most would find necessary, but beyond that, need is extremely difficult to define if you’re not a politician standing for election. As such, our hard heads have problems rationally determining how to implement what our soft hearts desire. Sadly, further inherent inconsistencies exist in such a “simple” principle; such sentiments also bear a strong resemblance to the Marxian maxim, “from each according to his ability, to each according to his need.” Blinder, not a fan of rational expectations anyway, tends to discount some of the worst psychological effects of macroeconomic policy. For example, Charles Murray’s thesis in Losing Ground (that the Welfare state caused further regression into poverty by incentivizing single mothers to stay unmarried and out of work) might apply to several policies of income redistribution. Of course, Blinder has no visible problems with Welfare, Medicare, and Social Security (the holy trinity of the Welfare state), even though he later decries programs that take the hypothetical $10 from 25 million people and give 100,000 people $1,000 each. This is not to say that the Welfare state bears similar proportions, but the action is essentially the same: one group of people subsidizes another group of people by government mandate. Blinder’s purpose in using such an example is to show that government solutions often pander to special interests; however, it also demonstrates how government solutions unnecessarily pander to the people as well. Take the 2001 Bush tax cuts, for example: everyone currently paying taxes in America stood to gain from the bill at the expense of future generations of Americans who would have to foot the bill (if we lived in a semi-Ricardian world, anyway). Such policies provide reasonable counterexamples to Blinder’s explanation that parochial politics is all to blame; even presidents have constituencies: living, taxpaying Americans. However, the process of such pandering does have immense negative economic repercussions as Blinder points out.
Blinder attributes problems in most policies to poor or unintelligent policy design, products of a political system presently incapable of sufficiently sophisticated economic policy. In this sense, Blinder is right; since Aristotle, observers have noted the failures of democracy in achieving a just or stable system of redistributive justice. As Blinder goes on to show, these failures can be traced to the Constitution itself, which establishes a geographically-defined representative democracy. Blinder then poses the idea of random representation as a supposedly more equitable hypothetical, but admits that this destroys the concept of actual representation and would lead to near uniformity in politicians. While Blinder puts stock in the idea of linkage as a potential solution, this solution relies on individual politicians to establish the links themselves, rather than mechanisms, as all good economists would prefer. Some institutional changes that might make the legislature less dominated by “ignorance, ideology, and interest groups” include the use of more bipartisan committees, such as BRAC (Base Realignment And Closure), which Congress found to be the only way to vote to stop outdated military bases from hemorrhaging funds. Another possibility would be to increase some of the secrecy of Congress, making it more independent of interest group lobbyists. By closing markup sessions of bills, congressmen would be able to edit legislation without having special interests watching their investments, ensuring their influence on policy formulation.
Blinder’s discussion of the possibilities of the hard head, soft heart combination are absurdly simplistic, given that he’s suggesting using a hard head to parse out the efficacy or desirability one’s soft-hearted emotions. For one thing, he essentially claims that the Democrats have gotten the “ends” right, while the Republicans have a good grasp on the “means” (even though this is promptly mitigated by his examples of political stupidity). Perhaps Blinder is simply wrong about a lot of his unexplained assertions. Perhaps justice in income redistribution is irreconcilable with democracies or, more contentiously, justice in general. Perhaps Blinder’s metaphor of the rich man absentmindedly losing a $100 bill and not noticing does not correspond to the reality of taxation (where, as Barro shows, people vehemently resist attempts by the government to extract resources for social programs and spending). Perhaps reality does match Blinder’s specific exception to the legitimacy of his example: perhaps the government does act as a pickpocket. Perhaps the problem is with equity itself. Blinder says, “Conservatives must come to accept the principle of equity and realize that intelligently designed policies that promote equality need not interfere unduly with efficiency,” as though efficiency were the only grounds to reject such a principle. Perhaps conservatives simply believe that the people who generate money have a right to dispense with it as they please, or that a rich person may use their money to achieve a greater social or personal good than the government could. There’s also the possibility that some prefer the value of freedom to the value of equality. In short, nothing is as non-controversial as Blinder attempts to describe it, provided your head is hard enough.
To begin with, I have to say I was troubled with Barro’s solutions to many problems. After expounding for paragraphs to explain an issue he quickly states the “answer” with very little factual foundation. Quotes like, “Much smaller benefits from individual currencies would be enough to outweigh the saving in transaction costs from moving to a single currency,” and “In both situations the benefits from central planning are exaggerated and the rewards from competition are underestimated” are examples of broad statements which I felt weren’t sufficiently supported.
Anyways, on to things which were adequately discussed to create a conversation. One area which I thought held interesting but unexplored applications was his analysis of sports wages. Barro claims that athlete’s competitive wages are set far above the correct wages according to a social standpoint. This is due to the unique situation of sports where relative performance is more important than absolute performance. Barro quickly notes that, “The competitive interaction of sports teams differs from that among producers of ordinary goods,” because such competition doesn’t cause economic distortions. I think Barro’s claim that there is a unique situation surrounding sports is untenable or poorly described at best. Stock holders invest in corporations depending on the relative performance of its executives among other things. If GM headhunters convinced a Ford executive to switch teams, similar distortions would be seen as in the sports world. As a result, one could argue that such executive salaries might be much higher than the socially optimal level. Barro seems to leave the door open to attack of his normally libertarian values for the inclusion of salary caps on earning in a wide variety of fields.
Another interesting area touched on by Barro was provided by his comments on diversity. One of his explanations for supporting national division was that there is a “desire to have a reasonably homogeneous population within (a country’s) borders.” This claim is later restated in defense of decentralized government when he states, “The apparent chaos from this diversity should instead be viewed as a reasonably good match between public policies and the desires of residents.” In an aside he does mention examples to the contrary such as the
