PNAS 2015 ; published ahead of print November 9, 2015, DOI: 10.1073/pnas.1517038112AbstractPrior studies have shown that traders quickly converge to the price–quantity equilibrium in markets for goods that are immediately consumed, but they produce speculative price bubbles in resalable asset markets. We present a stock-flow model of durable assets in which the existing stock of assets is subject to depreciation and producers may produce additional units of the asset. In our laboratory experiments inexperienced consumers who can resell their units disregard the consumption value of the assets and compete vigorously with producers, depressing prices and production. Consumers who have first participated in experiments without resale learn to heed their consumption values and, when they are given the option to resell, trade at equilibrium prices. Reproducibility is therefore the most natural and most effective treatment for suppression of bubbles in asset market experiments. © 2015 Phys.org Commodity market volatility more perception than reality Other examples include the so-called dot-com bubble of 1995-2000, the stock market bubble of 1922-1929, and there was even a bubble in the uranium market in 2007. Often, speculative bubbles occur in the markets for durable goods, defined as an asset that does not quickly wear out. By contrast, studies have demonstrated that price-quantity equilibrium prevails in markets for goods that are immediately consumed, like milk shakes and haircuts; this is because the buyer and the seller never trade places, and the consumption value of the good is very high.A group of economics researchers at Chapman University in California, curious about production and trade in a stock-flow market for durable assets, treated the issue as a pure abstraction in a study recently published in the Proceedings of the National Academy of Sciences. They developed a model of a reproducible durable asset with several conceptual elements: First, the asset provides use value to its owner (dividends) through use.The asset depreciates over time. And suppliers can profitably sell newly manufactured units if the price is below the market price.They tested this model in two conditions: In the baseline treatment (BL), they suppressed the asset units’ option risk by requiring units to be held until they depreciated. The second condition was the resale treatment (RS), in which consumers were allowed to freely sell their units to each other, thereby competing with the manufacturer. The researchers found that the RS condition hindered prices from converging to equilibrium and degraded market efficiency. Additional sessions under the RS condition used participants who had prior experience in the BL. These sessions with experienced participants were referred to as RSX.The researchers found that there was much less resale in RSX than RS, and that resale in the RSX increased market efficiency more frequently. Consumers in the RS condition failed to optimally specialize as buyers, competing with the manufacturers by reselling their units. Resale was much more efficient when the consumers were experienced. The reason? Experienced buyers understood the consumption value of the asset. “Our statistical analysis gives us strong confidence that consumers were more focused on the consumption value of their units in the RSX than in the RS and consequently captured more gains from exchange,” the authors write. “This affected price and production convergence, as well as efficiency…”Other results: Prices converged to the short-run equilibrium in the BL and RSX, but diverged from it in RS. Production converged to the steady state in BL and RSX, but diverged in the RS. And the efficiency was the lowest in the RS, according to a measure of global efficiency for each period. The researchers conclude, “Resale alone—although destabilizing—does not generate price bubbles. Over the past quarter century, numerous real estate bubbles have occurred around the world, with serious economic consequences. Our design with reproducible assets suggests that these markets should be stable unless other factors such as credit, cash infusions, and limitations on production disrupt market equilibrium.” Citation: How experienced buyers can mitigate economic bubbles (2015, November 19) retrieved 18 August 2019 from https://phys.org/news/2015-11-experienced-buyers-mitigate-economic.html This document is subject to copyright.

But property isn’t the only asset class that experiences economic bubbles; any asset valued at a price or a range that deviates sharply from its intrinsic value is said to be experiencing a bubble.last_img read more

Amazon has released an app that allows you to use Alexa on any Windows 10 PC.Previously, you could use Amazon’s voice assistant on Windows 10 PCs through Microsoft’s built-in voice assistant, Cortana.

Alexa on Windows 10 can read you the news, tell you a joke, play music and perform most of the other things that Alexa can do on an Echo device. (It can’t yet make calls or control Spotify or Pandora).But there’s one difference that fundamentally changes the experience. When you’re using an Echo device, you just need to say “Alexa” to trigger the voice assistant. However, this functionality is available only on “supported” PCs.MORE: The One Alexa Feature You Need to Turn OffI haven’t been able to find a list of supported devices, but the Razer Blade 15 and the Surface Book 2 (which I also tried) do not support it. (And some reviews indicate that even supported devices aren’t yet responding to the wake word). I could control Alexa only by clicking a button in the app.Call me a traditionalist, but this feels unnatural to me. The most compelling aspect of Alexa has always been that I could issue instructions hands-free, without leaving my couch or bed, or pausing my cooking.To use Alexa on a PC, however, I have to be sitting at my computer with the app open already. At that point, why click a button to ask Alexa to play music, when I can click another button to play the music myself? For many tasks, it seems like a needless middleman.It might also be difficult for Alexa veterans to get used to. I repeatedly found myself barking “Alexa, stop,” before remembering that my voice command wouldn’t work until I pressed a button.There’s one potential benefit I can think of to this setup: visuals on the screen. Unfortunately, Alexa didn’t make much use of these on my computer.When I asked for the weather, the app displayed an array of black-and-white icons (minus a blue outline along the rain clouds) to accompany the forecast. The Echo Show and Echo Spot both display much prettier visuals.MORE: How To Use Cortana on Amazon Alexa DevicesAnd PC Alexa, while playing music, displayed only a small soundbar on the bottom of the app window for pausing or changing the song, and a small picture of the album cover. The Echo Show and Echo Spot, by contrast, usually display album artwork alongside the song they play, and sometimes even the song’s lyrics.I also couldn’t get Alexa to pull up YouTube videos, the way it can on the new Echo Show. But again, I can do all these things on my computer already. So why would I need Alexa for it?I’d love to start using the PC version of Alexa when it takes full advantage of the computer screen, when it can control specific Windows 10 features, and when more computers support hands-free use. Until then, it doesn’t add much to my life.Credit: Laptop MagBest Amazon Alexa Skills – Top 50 Cool and Useful Things15 Alexa Speakers, Ranked from Best to WorstShould Alexa Be Your Child’s Friend?last_img read more
