Blog: Marginal Revolution | My trip to Karachi — "There is no subway, and a typical street scene blends cars, auto-rickshaws, motorbikes and the occasional donkey pulling a cart. It’s fun for the visitor, but I wouldn’t call transportation easy. And yet to see only those negatives is to miss the point. Markets speak more loudly than anecdotes, and the population of Karachi continues to rise — a mark of the city’s success. This market test is more important than the aesthetic test, and Karachi unambiguously passes it."

Blog: Marginal Revolution | Dining out in Karachi — "As in India, the hotel restaurants are excellent, and you can sample everything you might want without leaving a single restaurant, if you find the dust and heat too daunting (I do not, but you might, please do believe me on that one). The crowning glories in Karachi are the biryanis and the lassi. A randomly chosen lassi here seems to match the very best Indian lassis in quality. The karahi dishes come alive like nowhere else. Qorma sauces too. Vegetables are hard to come by, especially greens — the restaurant version of Karachi cuisine is quite meat-heavy, and the overall selection of dishes is not so different from what you find in the Pakistani restaurants in Springfield, Virginia. That said, the greens and herbs that accompany the meat dishes are fresh and vibrant."

Blog: Marginal Revolution | How strong is the evidence that the EITC boosts labor supply? — "Overall and contrary to consensus, the case for sizable extensive margin effects of the EITC is fragile. I highlight the presence of informational frictions, widely documented in the literature, as a natural explanation for the absence of extensive margin responses."

Blog: Marginal Revolution | Why do rates of entrepreneurship vary? — "Rather, the evidence shows that the strongest predictors of cross-national variation in entrepreneurial activity were normative, with social norms being the most strongly associated with entrepreneurialism and rates of organizational founding."

Blog: Marginal Revolution | The ho-hum of environmental politics — "We show that a majority of the public supports policies to protect the environment. But the environment is rarely the most important issue for voters, and thus the environment usually does not have a large impact in elections. Moreover, there are increasingly large divisions between Democrats and Republicans, which incentivizes politicians from both parties to embrace extreme positions..."

Blog: Marginal Revolution | Oversight of cost overruns does not always help — "We identify our results using a federal bylaw: if the project’s budget is above a cutoff, procurement officers actively oversee the contractor’s operations; otherwise, most operational checks are waived. We find that oversight increases delays by 6.1%–13.8% and overruns by 1.4%–1.6%. We also show that oversight is most obstructive when the contractor has no experience in public projects, is paid with a fixed-fee contract with performance-based incentives, or performs a labor-intensive task..."

Blog: Marginal Revolution | How to reform the economics Ph.D — "I have a modest proposal. Eliminate the economics Ph.D, period. Offer everyone three years of graduate economics education, and no more (with a clock reset allowed for pregnancy). Did Smith, Keynes, or Hayek have an economics Ph.D? This way, no one will assume you know what you are talking about, and the underlying message is that economics learning is lifelong."

Blog: Marginal Revolution | The Intuitive Monty Hall Problem — "There are three boxers. Two of the boxers are evenly matched (no draws!); the other boxer will beat either them, always. You blindly guess that Boxer A is the best and let the other two fight. Boxer B beats Boxer C. Do you want to stick with Boxer A in a match-up with Boxer B, or do you want to switch?"

Blog: Marginal Revolution | Pollution, Climate Change and India’s Choice Between Policy and Pretense — "As Spears shows, pollution is killing Indians, especially babies, and those it doesn’t kill it harms as seen in statistics on stunting and respiratory disease. Spears isn’t naive, however, he knows that manufacturing is also bringing tremendous benefits. The issue, however, is that a lot of pollution in India comes from relatively low value activities like burning crops. Moreover, solar power in India is cost competitive with coal today, even before taking into account health benefits. Thus, the harms of pollution are tragic because they are unnecessary..."

Opinion: Bloomberg Quint | Israelis Just Saved Their Democracy — "What a Gantz administration would show American Jews is that the occupation wasn’t Netanyahu’s doing — it is the product of a world in which Israel tragically has no good alternatives. Gantz the general may not be as reticent about hitting back at Gaza as has been Netanyahu; he may actually decide to batter Hamas, the radical faction that governs that benighted sliver of Arab territory, because he understands the status quo is untenable."

Mark Zuckerberg, Jeff Bezos, and the Koch brothers all have images or iconic photos that can be put into a social media post, amplifying any attack on their respective companies. It is harder to vilify Exxon, in part because hardly anyone can name its CEO (Darren Woods, since 2017), who in any case did not create the current version of the company..."

Blog: Marginal Revolution | The college football surveillance culture that is Alabama — "Saban, the Alabama football coach, has long been peeved that the student section at Bryant-Denny Stadium empties early. So this season, the university is rewarding students who attend games — and stay until the fourth quarter — with an alluring prize: improved access to tickets to the SEC championship game and to the College Football Playoff semifinals and championship game, which Alabama is trying to reach for the fifth consecutive season. But to do this, Alabama is taking an extraordinary, Orwellian step: using location-tracking technology from students’ phones to see who skips out and who stays."

Read that again. I didn’t say China had 40% of the world’s tallest (which would be a major achievement), I said a poor, small province in the interior with only 2.5% of China’s population has 40 of the world’s 100 tallest bridges." h/t Tyler Cowen.

Blog: Marginal Revolution | Consumers seem to like search engine advertising — "We analyze a large-scale field experiment conducted on a US search engine in which 3.3 million users were randomized into seeing more, or less advertising. Our data rejects that users are, overall, averse to search advertising targeted to them. At the margin, users prefer the search engine with higher level of advertising."

Blog: Conversations with Tyler @ Medium | Samantha Power on Learning How to Make a Difference — "I was very fortunate — but again, it’s not a common circumstance — to be both a diplomat representing the United States and a member of the president’s cabinet. I was able to spend enough time with President Obama to have a sense not only of what my explicit instructions were, but where the gray areas were at the margins and how far to push." and "[S]ome students will come up to me and say, 'I want to be America’s ambassador to the UN. How do I go about doing it?' And I’ll say, 'Well, not that way, probably.' Because if you focus on the title rather than what you want to do in the world, you’re probably not going to get very far. But some people are drawn to power, to the position or whatever."

Blog: The Grumpy Economist | Intellectual property and the trade deficit — "'The IP Commission estimates that between $200 billion and$500 billion a year of intellectual property is stolen from the U.S.'... Well, suppose China were to pay up, and pay the $200 to$500 billion a year in royalty payments. Where would it get the money from? Hmm. It would have to sell us an additional $200 to$500 billion worth of exports, that's how. The trade deficit would have to increase."

Blog: Marginal Revolution | Active Learning Works But Students Don’t Like It — "A carefully done study that held students and teachers constant shows that students learn more in active learning classes but they dislike this style of class and think they learn less. It’s no big surprise–active learning is hard and makes the students feel stupid. It’s much easier to sit back and be entertained by a great lecturer who makes everything seem simple."

Still, I get very nervous when I am in a 'collectivo' on a mountain road and the driver appears to be no more than 15 years old and is fond of loud music and beer."

Blog: Marginal Revolution | Is this the very best book ever written? — "No, I don’t mean Proust, Cervantes, or the Bible. I mean Dave Marsh’s The Heart of Rock and Soul: The 1001 Greatest Singles Ever Made. To be sure, it is not the greatest book qua book, or even in the top tier (though it is very good and Marsh is very smart and knowledgeable). It is possible it has become the greatest book of all time because of YouTube. Scroll through the pithy, one-page or sometimes even one-paragraph reviews of the various songs, and play them on YouTube while you are reading."
