Creative destruction, illustrated

Swiss watch exports suffer largest decline in 6 years following Apple Watch launch
Despite earlier bluster and claims that traditional mechanical watch buyers wouldn't be drawn to smart watches, some Swiss watch companies now seem to be doing an about-face and are embracing the idea of smart technology on the wrist. TAG Heuer released a "smart" version of its famous Careera watch earlier this month, which runs on Google's Android Wear platform and retails for $1,500.

How is Development Econ taught in developing countries?

Interesting research from the WB:

Next time I'll incorporate data crunching in the exam; quote:
[D]eveloping country classes largely rely on written exams, essays, and presentations, and very rarely require students to use statistical software or answer...

Cointegration and drunkards

A rather creative stylized description of cointegration:
Suppose you see two drunks (i.e., two random walks) wandering around. The drunks don't know each other (they're independent), so there's no meaningful relationship between their paths. 
But suppose instead you have a drunk walking with her dog. This time there isa connection. What's the nature of this connection? Notice that although each path individually is still an unpredictable random walk, given the location of one of the drunk or dog, we have a pretty good idea of where the other is; that is, the distance between the two is fairly predictable. (For example, if the dog wanders too far away from his owner, she'll tend to move in his direction to avoid losing him, so the two stay close together despite a tendency to wander around on their own.) We describe this relationship by saying that the drunk and her dog form a cointegrating pair.

Optimal bibliography

Where Becker went wrong

Excerpt from Tabarrok on MR:
Inspired by Becker, a large, credible, empirical literature–including my own work on police (and prisons)–has demonstrated that this is no myth, the police deter. Score one for rational choice theory. It’s a far cry, however, from police deter to twenty years in prison deters twice as much as ten years in prison. The rational choice theory was pushed beyond its limits and in so doing not only was punishment pushed too far we also lost sight of alternative policies that could reduce crime without the social disruption and injustice caused by mass incarceration.

Restaurants vs. groceries

In the US, food consumed from restos & bars have overtaken food consumed from grocery stores (in terms of value in USD). I think a similar trend is happening in the Philippines with the proliferation of new restos and food concepts around the Metro.

Population pyramid of the Philippines: 2015 vs. 2040

By 2040, we'll feel the bulge in the middle, and those aged 15-24 will be the most populous (no longer those aged under 5). Source of data: PSA Census projections (medium assumption).

Historical Philippine unemployment data

The Philippine LFS or Labor Force Survey actually goes way back 1956. However, changes in definitions, sampling methodologies, etc. over the years have resulted in at least 6 distinct series of unemployment data that cannot be compared with one another one-for-one (see graph below).


So how do we assess the Philippines' unemployment situation? According to NEDA staff, indeed the best possible statement to make is that 2014's unemployment rate of 6.8% is the lowest since 2005, the earliest year against which today's unemployment data can be compared. (Still, one must be mindful that 2014 data exclude Reg. VIII due to Yolanda.)

Economists on the hot seat

Data "scraping" and Argentinian prices


From the Conversable Economist:
Researchers can create their own data sets by "scraping" the web: that is, by writing programs that will download data from various websites at regular intervals. One of the best-known of these projects is the Billion Prices Project run by Alberto Cavallo and Roberto Rigobon at MIT. Their program downloads detailed data on prices and product characteristics from websites all over the world every day on hundreds of thousands of products. For a sense of the findings that can emerge from this kind of study, here's one graph showing the US price level as measured by the Billion Prices Project and the official Consumer Price Index. They are fairly close. Next look at the price level from the Billion Prices Project and the official measure of inflation in Argentina. It's strong publicly available evidence that the government in Argentina is gaming its inflation statistics.

2015 Clark Medalist: Roland Fryer Jr.

From the AEA website:
Roland Fryer is an influential applied microeconomist whose work spans labor economics, the economics of education, and social problems and social interactions.  His innovative and creative research contributions have deepened our understanding of the sources, magnitude, and persistence of U.S. racial inequality. He has made substantial progress in evaluating the policies that work and do not work to improve the educational outcomes and economic opportunities of children from disadvantaged backgrounds.  His theoretical and empirical work on the “acting white” hypothesis of peer effects provides new insights into the difficulties of increasing the educational investments of minorities and the socially excluded.  Fryer is the leading economist working on the economics of race and education, and he has produced the most important work in recent years on combating the racial divide, one of America’s most profound and long-lasting social problems.
He has mastered tools from many disciplines to tackle difficult research topics.  Fryer has developed and implemented compelling randomized field experiments in large U.S. urban school districts to evaluate education interventions.  He founded EdLabs (the Education Innovation Laboratory at Harvard University) in 2008 to facilitate such efforts and continues as its director.  He has incorporated insights from psychology to formulate a new model of discrimination based on categorization, and he has used detailed historical archival research to understand the origins and spread of the Ku Klux Klan.

Is a masteral degree still worth it?

Link. Quote:
In conclusion, modern graduate schools attract talented workers, but often not the best. The opportunity and monetary cost associated make these schools obsolete for the most talented individuals. In 2015, top firms should focus on undergrads when recruiting.It

Infographic of the day: Hispanic America

Perhaps the most striking bit is that by 2050 less than half of the US population will be white. So the average American by then will only be half-white!

Latest from Reinhart & Rogoff

From their 2014 paper entitled, "Recovery from financial crises: evidence from 100 episodes" (pdf):
Now entering the sixth or seventh year (depending on the country) of crisis, output remains well below its pre-crisis peak in ten of the twelve crisis countries. The gap with potential output is even greater. Delays in accepting that desperate times call for desperate measures keeps raising the odds that, as documented here, this crisis may in the end surpass in severity the depression of the 1930s in a large number of countries.

History of supply & demand

Here. Excerpt:
Economists usually see Alfred Marshall as the originator of standard demand and supply diagrams and their use in economic analysis including welfare applications and consumer surplus. However, it turns out that Marshall’s diagram was not the first use of demand and supply curves. Cournot originates a scissors type diagram to illustrate tax incidence in 1838 that has a demand and a supply curve with price on the horizontal axis and quantity on the vertical axis. Indeed, at least five economists used similar tools before Marshall published it – Antoine Cournot (1838), Karl Rau (1841), Jules Dupuit (1844), Hans Von Mangoldt (1863) and Fleeming Jenkin (1870). According to Humphrey (1992), these individuals were largely unaware of the others work.

Excerpts from UPSE's 50th Anniversary Gala Night

Quote from the ever eloquent and poetic Dean Fab:
On teaching. That the UPSE faculty maintains a romance with creative thinking should be a given; it should however maintain on the side a romance with the tuition of its harvests. In UPSE, we did not and in future shall never tolerate the neglect of our tutees on the pretext of more important involvements. There are none such. Our tuition is the precious pipeline for the propagation of our DNA and to a better future. 
In the past I have as a mark of endearment referred to UPSE as “Camelot”. The roots of this imagery goes back to the 80’s when UPSE stood as a forlorn and even maligned contrarian in the University campus: it stood for the market economics when the most swore by the Socialist command economy. We were labeled the imperialist running dogs, stooges of the hated World Bank and IMF and even jukebox economists. Nonetheless, as Pepe repeatedly observed, “we were outnumbered, but were never outgunned.” If we were on trial, we pleaded guilty only to “rigor of logic and clarity of thinking.” UPSE like Camelot was a beacon of light then; UPSE will be a Camelot thence.

Study on class attendance?


Actually, I can do this too with my Econ 191 class! More here from Harvard.

Competition vs. cooperation

A thoughtful piece by the Conversable Economist, Timothy Taylor:
Cooperation refers to a situation in which the participants seek out win-win outcomes from working together. Thus, the opposite of cooperation would be a situation in which such win-win outcomes are difficult or discouraged. For example, this could reflect a situation of lawlessness or a set of social norms in which people expect that cooperative agreements are likely to be broken—and, thus, the incentive to cooperate is low. 
If both competition and cooperation are understood as voluntary choices (and, after all, "involuntary cooperation" is an oxymoron), then a fully planned economy would be the opposite of both competition and cooperation. When government dictates prices and quantities, a planned economy eliminates the incentives of market participants—whether suppliers, producers, or consumers—either to compete or to cooperate.

Those of us who self-identify as economists should not wear the terminology of "competition" as a badge of shame, while wistfully contemplating a presumed ideal of cooperation. For the study of economics, as in the real-world economy, the concepts and practices of competition and cooperation are inevitably interlocking.

History of the Gerry Sicat Award

Dr. Sicat writes at the Philippine Star about the history of the award named after him at the UP School of Economics:
The GPS awards. Allow me a moment of immodesty and to talk about something that I am very proud of. It might be, in the scope of things, very small. But the end product has turned up very positive for the students and the School. 
I refer to the so-called “G.P.Sicat awards” for the most outstanding undergraduate papers at the School. In 1972, I was no longer in the faculty because I was actively engaged in national economic affairs. I suggested to both Drs. Amado Castro and Jose Encarnacion, Jr. that I contribute a small award to give a prize to the most outstanding paper by a graduating senior. To make it possible, I started a small fund. Through the years, the small fund grew, and, especially after 1983, royalties from my Economics text filled it further. It was able, even, by the 1990s, to sponsor at least an annual graduate scholarship too. 
From 1973 to 2014, a total of 206 student were recipients of the GPS awards among the best graduating papers. Had the original plan of a yearly prize for only one paper each been followed, there would have been only 41 prizes. 
Dean Philip Medalla apprised me, when I was working in Washington D.C. at the World Bank, that the quality of student papers had gone up, that the best students were spending their time writing on a variety of relevant development topics in economics, and that on commencement day when the award was also announced, the GPS award became among the most coveted by the top-rung graduating students.
It's quite a privilege to have been part of this institution! Here's to the golden year of UPSE!

Graph of the day: US crude oil production

An unprecedented increase in the past 5 years! Looks like the new age of cheap oil is here to stay.

Plotting activity of the day: SWS hunger data

From (largely) quarterly SWS data on total hunger incidence (% of households who experienced having nothing to eat at least once in the past 3 months)...


...I got this trend line with a polynomial fit (order=6) superimposed. I tried reverse engineering an existing line graph online using PlotDigitizer when I had no data to work on, but it turned out to be largely inaccurate unless the data points were identifiable.

The permanence of negative growth shocks

This recent post on Econbrowser is worth reposting in full.

Suppose that output Y grows at 1% quarterly in log terms.

Then a 2 percentage-point drop in one quarter will permanently decrease the trend even if growth reverts back to the pre-shock level in the succeeding quarter.

The only way to revert back to the pre-shock trend is to balance the 2-ppt drop by a subsequent 2-ppt increase in a subsequent period. 

This simple illustration resonates with the economic crises experienced during the Marcos era, which undoubtedly had permanent negative effects that we are only recently counteracting with stellar growth. Our future leaders should take heed of these potential permanent effects.
