An n-Sector Migration Simulation
It's based on a Two-Sector Migration Model inspired by Harris and Todaro and applied Agent Based Simulation aligned to Axtell’s Emergence of Firms to build "An n-Sector Migration Simulation".
Here is the abstract:
"Workers, considering costs of migration, tend to migrate to sectors where they expect higher wages. In revers, ﬁrms trying to increase proﬁts, migrate to sectors with lower wages. The result of their combined movement determins wages in each sector. This Agent Based Simulation applies an inductive behavior models with various strategies for wage expectations, and yields patterns of migration in an n-sector scenario."
Here are some results:
Nomads work and love
The report describes how today's ubiquitous mobile technology allows us to work, live and love like nomads (wanderer), without staying long in the same place.
Our documents, spreadsheets, contacts, calenders,... are always available online in the cloud. So unlike previous nomads, we don't have to carry much weight. An iPhone like device may do. Where ever we are we can sit down, do some work, play around with ideas or catch-up with customers, coworkers, or friends and family.
Who wants to be at the office from 9 to 5? If I'm working, does it matter if I sweat in a cubicle or enjoy fresh air in the park? Of course it does! And reading this report just gave me additional encouragement to stay out of that cubicle.
For some an office may be great to get focused, while others prefer a beach. If you find yourself bored or in need for inspiration, get moving. (Right now, I'm in a coffee shop, but that beach looks inviting). In the end, where we are becomes secondary. What counts is that we get things done and spend time with those we love.
Or, as Sigmund Freud put it, Menschen müssen arbeiten und lieben um Erfüllung zu finden (humans must work and love in order to find fulfillment). Mmm, I love it when The Economist runs quotes like that.
I'm pleased with my time (4:30:40). If I keep running, maybe I can beat 4 hours next year.
OK, I will fall asleep now and pray that I can still walk tomorrow.
Intuitively we understood the working of the free market. We improved the lot of our players and the coffee owner, simply by pursuing our own self-interest. It was a win-win-win situation.
Unfortunately after only a year we had to stop our business. Our parents insisted that school was more important. (Through this, we learned how regulations can limit the market.)
After high school, I decided to study information systems but never left economics. I took all available economics courses and read every book I could get my hands on. Now, after being close to finishing my master in information systems, I want to proceed with a master in economics.
In my future career I hope to pursue both, my interests in economics and computer science.
Additionally Lutzi recommends noodles, potatoes, fish, eggs, chocolate and bananas. Which sounds like my current diet anyway.
My Goals for 2007
Here is my take for 2007:
- Finish Master of Science (MSc).
- Find new customers for software projects.
- Run a marathon in less than 5hours. First chance, April 29th in Vienna.
- Improve derbaum.com so actual people care to read.
- Enjoy doing so!
- 20 runs
Incentives for running
Last week I bought additional motivation. It's called Nike+iPod and snaps on your iPod and in your running shoe (doesn't have to be a Nike). It measures your time, speed and distance. And it gives sexy voice feedback on the run. After running when you connect your iPod with your PC (doesn't have to be a Mac), you get stats which of course you have to beat next time.
With Nike+iPod I set myself three goals for the next four weeks:
- 20 runs
- with an average speed of less then 5min30sec/km
- and 100km in total
Magnum P.I. Night (3)

Magnum P.I. Night (2)
Magnum P.I. Night (1)
For those who don't remember. Magnum is a private investigator (P.I.) in Hawaii. His lifestyle represents every man’s dream. He comes and goes as he pleases, works only when he wants to, has the almost unlimited use of a Ferrari 308 GTS as well as many other luxuries, keeps a mini-fridge with a seemingly endless supply of beer, comes into contact with countless beautiful women (who are often his clients or victims in the cases he solves).
While waiting for the Magnum Night, enjoy the title music:
Magnum, P.I. was first aired in 1980.
Lift that Laundry Machine
This week Johannes, Stefan, Konrad and Patrick took off to visit Luzi in Hamburg.
A fun and thanks to sparnight quite cheap trip. But the city was a mess (see below). Trash everywhere. Garbage collectors are striking to protect there 38.5 hour work week against a 40 hour work week.
At first sight unrelated, Stefan found some great underwear at Wal-Mart. Why is that exiting? Well Wal-Mart itself is exiting. I just started collecting facts for a paper about Wal-Mart's data warehouse and I'm blown away. This single company drives world wide productivity in ways never seen before. Simply by demanding everyday low prices.
Sadly this pressure scars workers all over Europe into striks aging the open economy.
Addition: After eight years in Germany, WalMart announced in July 2006 that they will aboundant their business in Germany.
Schneespaß in Oberösterreich
Sure thing we had to get on a plane to stop by and celebrate.

It's getting cold in Austria and everybody is happy to see the wintertime. Sure thing we had to celebrated the start of this great time.

Der König der Welt
Grillfest zu Pfingsten
- As shown at derbaum.com, I brought back some fun movie clips: Wiesenski, Caribbean and The Secret Ingredient.
- During this summer (June 20th till Aug 17th) I'm going back to Stanford to study Physics.
- That's why I give up my apartment in Marokkanergasse. It was good place, but now I have to move on.
- Currently I'm working on an LP on scheduling, which I may inlcude in future version of Caltella. In short, this should find an optimal schedule for one or more person, regarding a certain task, with the goal to maximise spare time.
- Looking at the above task, the field of Operation Research seems very interesting to me. A field where I can combine my interst in math, economics and computer science.
Silvester in Flachau
Yet another Ballnight
The Secret Ingredient
It all started with a pre party on the 29th of December and we partied until the new year.
Thanks to everybody for joining!
A new year, a new Macworld (Monday)!
Since the winter semester is almost over, there are many exams this month.
Café in Palo Alto
People try to help me and point me to there favorite Cafés in town and so, every time I give it another try to find a Café which fulfills my few basic needs.
It's Palo Alto, for gods sack, a small town yes, but one of the richest one in the world. There must be some place serving descent coffee. Yes, I like Starbucks coffee, but the coffee is not served. So what are my basic needs?
- a cup of coffee (expresso, preferable with hot milk in a cup)
- newspaper (not just tabloids)
- service (yes, indeed)
So why is that? Is it because of missing demand, do Americans prefer the freedom to get there coffee them self, waiting in line? Perhaps to chat up other people in line???
This bothers me, so I keep on talking with American's about that. Asking why? I try to explain, why Austrian Cafés have better service, but nobody seems to get my point.
One explanation, starts with the waiter in mind. The idea of serving coffee, or serving in general, is labeled as a poor job. Which nobody likes to do. Unlike in Austria where we call the waiter Herr Ober, which is considered the highest position in the shop. So being the Ober is something people can be proud about. You can tell, just by watching the Ober. His movement has to follow a certain style and arrogance. He knows, it's something not everybody could do. He has a tradition to keep up. Vienna is known for there Café's and it is his responsibility to keep the high standard up, for another century.
So as long as I'm here I have to live with this barbarian baristas, who drink there coffee in paper cups, while walking the street.

But I didn't find any satisfying coffee house in P.A. during the year I stayed at Stanford. Neither did my classmate from China. (we made joint effort in the search sometimes.) And my standards on coffee house are apparently not as high as yours. Good luck.

Two days ago Andy and Patrick climbed the Traunstein!
Well I spend a week in Romania.
We, Cornelius, Daniel and I, started our trip on Thu (4th April) very late and came back yesterday (10th April).
We didn't plan to stay that long. But unexpected things turned up, so we became prisoners of Romania. But let me start from the beginning. After a night of driving we arrived the first city in Romania, Arad just in time for breakfast. We looked around a bit before we drove on to Timisoara where the unexpected happend. While we drank a coffee in a bar somebody stole Daniels passport. Ops, we can't drive out of Romania without a passport. So we had to go to Bucharest and find the Austrian Embassy. On the way to Bucharest we stopped in Sibiu and Brasov where we spend the weekend. It took until Tue (9th April) to get a new passport. Anyway, now we are back and yes we had a good time!
Die Lipizzaner der Gastronomie
Besonders treffend analysiert fand ich folgenden Teil: "Der "gute Gast" zeichnet sich dadurch aus, da§ er niemals und unter keinerlei Umständen gegen die vorgegebene Etikette aufbegehrt oder dem Ober gar "Ezzes" geben will. Er bleibt, ganz im Gegenteil, stets bemüht, sein Wohlwollen mittels guter Manieren und diskret verabreichter Trinkgelder zu erhaschen. Kurzum, der "gute Gast" beweise immer seine lang geübte Anpassungsfähigkeit, die ihrerseits den milden Stolz des Obers ausmache, heist es im Vorwort zum Buch "Kaffeehäuser in Wien" von Thomas Martinek. Der "schlechte Gast" hingegen bleibt nach diesem Urteil ein Phänomen der Kaffeehausgeschichte, an dem schon die grö§ten Geister gescheitert sind. Betreten nach seinem verschollenen Bohnengetränk Ausschau haltend, das nicht und nicht kommen will, während ringsum alles genusvoll an den Tassen nippt, wird das Unglück des "schlechten Gasts" vollkommen, reklamiert er vielleicht nach zwanzig Minuten vergeblichen Wartens völlig deplaziert seine Bestellung - peinliches Schweigen. Nicht nur der Befragte, auch sämtliche seiner "guten Gäste" werden ihre Blicke sogleich angewidert abwenden - der Ober, um seine Dominanz anschaulich unter Beweis zu stellen, jene, um sich ihrer wohlerworbenen Privilegien zu erfreuen, heist es dort weiter."

Nachtrag vom Februar 2006: Dieses "Schema" hat inzwischen einen wohl bekannten Namen: Blog.
Am Samstag, den 23.1.99 rief Tanja bei Patrick an und erzählte vom Alxometer 2.
Alle waren sofort dabei, Patrick verständigte gleich Andi, Olivia und Stivi.
Die 3 sollten sofort dorthin kommen, denn jeder wusste wie die erste Version vom
Alxometer verlaufen war. Voller Euforie machten wir uns auf den Weg, doch Patrick
musste sich noch in Schale werfen: das PRIVAT-PARTY-OUTFIT war gefragt.
Dort angekommen, stellten wir bald fest, dass das Alxometer in Wirklichkeit das Alxinger Gschnas war, und dass der Altersschnitt im Vergleich zum Alxometer etwa um 50 Jahre hoeher war.
Patrick schloss schnell Freundschaft mit den etwas reiferen Leuten, auch Peter passte sich an die etwas gediegeneren Umgangsformen an.
Eine coole Band spielte gross auf! Der Liedsänger koennte sicherlich den Songkontest gewinnen, aber egal.
Bald erfreuten uns Andy, Olivia und Stivi mit ihrer Anwesenheit, der Abend schien doch noch einigermaﬂen interessant zu werden.
Durch die Offenheit und Direktheit von Stefan Trimmel freundeten wir uns mit einem offenbar türkischen Herrn an, der uns gleich fragte, ob wir ein Problem hätten, Stivi verneinte.
Patrick wusste zwar schon, dass Andy den Bock der Woche geschossen hatte, doch er wollte es nochmals versuchen. Um K... vom letzten Alxometer zu ueberbieten, musste er sich jedoch gewaltig anstrengen, doch ihm gelang auch dies: der Freund der Schwester der Zwillinge, massierte ihn und gab ihm dann auch noch einen Kuss, okay ein Bussi, aber direkt auf den Mund! Patrick schien leicht verwirrt, aber dass kann täuschen, oder?
Als alle die nette ältere Dame, die Patrick ihre Handtasche zeigte, verabschieden wollten, blieb Nico am Tisch. Promt machte ihn eine FZJ an. Margot war ihr äh werter Name, ihre Telefonnummer ist 01-48-11-783. Nico verzog sich gleich mit ihr und wollte sein Mittagessen mit ihr teilen, jedoch verhinderte der Sicherheitsabstand alles. Leider gibts hierzu kein Foto.
Am Heimweg wollten wir uns noch gebührend von den "Veranstaltern", "Sicherheitsleuten", und netten reiferen Herrschaften verabschieden und machten Fussballstadion-Stimmung. Seltsamer Weise waren nicht alle begeistert.
Alxometer 2, we will never forget you, but please don' t get copied anymore!
