bill negotiators

Leave a reply

I just learned of two companies that will negotiate with your cable company on your behalf, in exchange for a share of the savings. Shrinkabill.com and BillFixers.com.

There should be a lot of business opportunities out there like this because we have so many subscriptions and bills now and they are so complex and screwed up. Beyond utilities, you have screwed up medical bills obviously. Shopping around for homeowners and car insurance periodically can really pay off. Then there are simple repairs and maintenance that can lower energy and water bills. Property tax assessments can sometimes be challenged successfully. Mortgage and other lending terms can be negotiated, and if companies are not willing to negotiate they can be refinanced or consolidated. And yet most of us are too busy to spend time doing all this. It wouldn’t make sense to take time off work to do it, and we don’t want to give up our limited family and leisure time. But if there are businesses out there who will do it for you and it puts a little money in both your pockets that wasn’t there before, it’s a win-win.

 

financial technology

Leave a reply

Here is an article about new “financial technology” by the author of a book called Money Changes Everything: How Finance Made Civilization Possible.

For example, even as we debate the relevance and usefulness of traditional financial institutions such as banks, another revolution is underway in the world of money. A mere decade after we thought we had mastered the intricacies of asset securitization, shadow banking and credit default swaps, an entirely new financial phenomenon has emerged. It is called FinTech – short for financial technology. FinTech involves the plumbing and wiring of the financial system. It is changing how we borrow, how we save, how we raise money for companies even how we assess our future; its possibilities, risks and relationships.

Some of these innovations you may already know: PayPal, Bitcoin, Financial Engines, Kickstarter, Prosper.com and Venmo. They are apps, payment systems, crowdfunding vehicles and peer to peer lending sites. Their use has spread rapidly along with other technological improvements in how we get things done. However these companies are the tip of a very large iceberg.

Many of the innovations in finance are buried in the complex, business to business infrastructure of the economy. These include new ways of detecting fraud, recording transactions, routing orders, valuing assets and even discovering hidden patterns in big data; massaging the fast, continuous flow of news, trades, tweets, satellite images, and Facebook posts. Financial companies – from the big players like Goldman Sachs and Blackrock down to your local bank and financial advisor believe FinTech will fundamentally alter their businesses — and they are rushing to get out ahead of competitors. This is because FinTech innovation tends to disrupt the existing structure. It disintermediates customers and providers of financial services, replacing them with peer-to-peer lending, instant money transfers, loans without loan officers, and investment without investment banks. These innovations are transformative, empowering and create a new infrastructure for exploring even greater opportunities but they threaten the status quo in ways that the securitization wave of the 2000’s never approached. Securitization mostly involved the same big players that ruled the markets in prior decades. FinTech brings a different cast of characters who are defining new communities of investors, new sources of knowledge and unfortunately new kinds of scams and risks. The top FinTech companies today include a lot of new names. How many of us have been following the likes of Credit Karma, Market Axcess, Square, Stripe and SoFi?

I’m all for cutting out the middlemen trying to rip us off. And I’m still looking for the perfect app for splitting a restaurant bill among a large party.

new technology for mapping street trees

1 Reply

Philadelphia Parks and Rec has used a Google Street View-like technology to map street trees.

CycloMedia’s tool is “like Google Maps on steroids,” said Parks and Rec’s lead GIS Specialist Nora Dougherty, who spearheaded the project. It is a way of capturing all kinds of high-definition imagery that is geolocated, which means it can be used for a variety of projects. The tool is easy enough for non-experts to use, according to Mark Wheeler, Chief Geographic Information Officer for the Office of Innovation and Technology, plus the custom-captured imagery can be fully integrated with the city’s existing GIS software. CycloMedia’s tool captures an unprecedented level of detail in the images it records: You’re able to see features like address numbers and even deterioration of rooflines. Plus, every image is date and time stamped, so the user can verify that the images are consistent. This tool is also highly accurate for measuring distances and heights.

After all the streets in Philadelphia were captured using the technology, GIS technicians Tom McKeon and Stuart Olshevski virtually traveled down every street and dropped pins marking the location of each tree. The result is an inventory of nearly 112,000 street trees with geolocation data, which means street trees are now represented in a new layer of geographic information that can be mapped and analyzed. (Forest trees make up the other thousands of trees in Philadelphia, but it’s nearly impossible to accurately inventory them.) Information about the health and species of street trees is also being recorded…

The street tree inventory will be available on August 5 on Open Data Philly, and in an interactive map will be on the city’s website. Citizens can use that information to create their own maps and take action to monitor the trees in their neighborhood.

skyscraper game

Leave a reply

This looks pretty cool – an iPhone game for kids that lets them look inside a skyscraper.

In a few light swipes and taps, users “create” a made-up skyscraper by adding floors and choosing the color of the facade. On the app’s sidebar, select a tiny I-beam button to play a game where adding boulders, elephants, and sailboats sinks your building deep and lopsided into its foundation. An elevator icon takes you to an interactive view of interior life—families in their kitchens, watching television, tiptoe-ing through bedrooms. The details are incredibly ornate, especially in another mode, accessed by clicking on a little water drop, where you clog toilets and set fires on different floors. Watch how the building (which gets an anthropomorphic touch) reacts. They say if walls could talk…

Problems just keep backing up.

With virtually no text, the app invites you to play by intuiting through touch and iconography. Youngsters, presumably raised on the logic of iPhones, are the audience targeted by the app’s developer, Tinybop. “Skyscrapers” is the seventh in Tinybop’s “Explorer’s Library,” series, which “introduces kids to STEAM topics they learn about in school,” according to a spokesperson.

I looked at the Explorer’s Library and they have a number of cool simulation apps for kids, like plants, the human body, and weather. I think I might start with one of those rather than a skyscraper. I am always on the lookout for a really good ecosystem simulation for kids.

This app turns your to-do list into a game. It’s a cool idea – basically you are setting goals and tracking your progress toward them, not exactly a new idea. But it could be a fun idea that gets you over the hump of a goal that has been eluding you, or the gimmick that gets a team of smart but bored individuals (and smart individuals have a tendency to be bored) to come together and complete an important but less than intellectually stimulating work task.

inequality and mobility

Leave a reply

The Federal Reserve Bank of Cleveland has an interesting study of income mobility in the U.S. It appears to be true that the poorest families tend to stay poor (between 2003 and 2013, 64% of families in the poorest 20% stayed in the poorest 20%), while the richest tend to stay rich (72% of families in the richest 20% stayed in the richest 20%). Looking at the table if you are in one of the middle quintiles, (between the 20th and 80th percentiles, your chances of moving up or down to the adjacent quintile look to be about even. This measure of mobility increased somewhat in the 80s and 90s, but appears to be on the decline since then. Mobility is harder to measure across generations, but it does appear to be much higher than within a single generation, which you would expect. Mobility in the U.S. is lower than in other developed countries, both the northern European socialist ones where you might expect it, but also the Anglo-American peers like Canada, Australia, and New Zealand, although the UK, France, Italy are in the same ballpark as the U.S. If you’re interested in this, stop reading my wordy description and go look at the data!

where the money goes

Leave a reply

I am somewhat familiar with how the U.S. federal government spends its money, but it is still instructive to see it broken down occasionally. Once social security, medicare, and interest are taken care of, the discretionary spending that is left is less than a third of the total. Of that, more than half is military. Veterans’ benefits make up another sizable chunk, nuclear weapons are partially funded under the energy budget, and it is not clear (to me at least) where intelligence and homeland security funding fall, so the real total for military and security is even larger than it appears.

index of redevelopment potential

Leave a reply

This is an index of redevelopment potential for individual properties in Philadelphia and other cities. The application to real estate is obvious, but I can also see a number of applications to public policy. For example, changes to codes and ordinances can improve the overall health, safety, and environmental impact of a city. But these get implemented slowly and incrementally, especially in older cities with fixed boundaries, where most development is redevelopment. If you had a reasonable prediction of where and when redevelopment is likely to occur, you would know which areas to sit back and be patient, and which areas of the city to intervene more directly if you want to see change on any reasonable time frame.

It’s a little bit of a shame the person is not sharing their methodology. I’ve had a number of urban planners and economists tell me over the years this is very hard to do, and seen a few try and give up. So this is either brilliant, or it is little more than a guess. If it’s brilliant it could be very valuable indeed, so I guess I can see the financial incentive not to publish the details. But there is no way to know the difference without knowing how it is done. The author could at least publish a white paper showing some back testing of the algorithm against historic data.
