A basic tenet of economics: Tax things you want less of. If you want people to, say, eat less candy, tax candy.
Economists, given that they are economists, have traditionally assumed that it doesn't matter when the tax is added to the price. Whether people see the tax reflected in the price of the candy when they grab it off the shelf, or whether the tax is added at the cash register, like sales tax, shouldn't make a difference.
A new kind of telescope buried deep beneath the ice of Antarctica has, for the first time, seen a signal from distant, violent events. In doing so, it is beginning to paint a picture of a part of our cosmos that has never been observed before.
Friday's 50th anniversary of assassination of President John F. Kennedy is an important moment for Dallas: The city wants to use the occasion to demonstrate how much it has changed.
In the 1960s — after the president's murder — Dallas became known around the world as "The City of Hate." And it was a hotbed of right-wing politics, a magnet for the extremes of the conservative movement at the time.
If the world would like to see evidence that Dallas is no longer the City of Hate, it need not look further than the Dallas Symphony Orchestra.
For the Bureau of Alcohol, Tobacco, Firearms & Explosives, nothing seems to come easy.
The agency runs at a fraction of the size of its much larger law enforcement counterparts. Under pressure from gun rights groups, it operated without a Senate-confirmed leader for seven years. And its new leader, B. Todd Jones, only narrowly averted a congressional roadblock to win confirmation this summer after serving more than two years as an interim leader.
The number of homeless people in the U.S. has declined for the third straight year. New numbers from the Department of Housing and Urban Development show a large decrease in the number of homeless veterans. Though there are still large numbers of homeless, mainly concentrated in large cities, including New York City and Los Angeles.
More than 200 Marines have been training since late September in the pine forests of North Carolina. They've been hiking for miles carrying 87-pound packs and assault rifles, sleeping in the field, attacking mock enemy positions.
And for the first time, women took part in the training. Three of them made it to the end and graduated Thursday morning.
They were there at Camp Geiger to answer the question of whether women have what it takes to become combat infantry Marines.
For the third time this year, the Democrats who run the Senate are threatening to change that chamber's rules on the Republican minority's most potent weapon: the filibuster. They say the GOP's obstruction of President Obama's nominations leaves them no other choice.
Democrats say that this time, they're ready to pull the trigger on what's known as "the nuclear option." Doing so would amount to altering the rules not with the traditional two-thirds majority but a simple majority of 51.
Bitcoin, the virtual currency that exists as alphanumeric strings online, is on the verge of getting into politics.
The Federal Election Commission is expected to vote Thursday on a proposal to allow bitcoin contributions to political action committees — even as skeptics say that bitcoins could undermine the disclosure standards of federal law.
