Prediction Markets
Prediction markets (also known as betting markets, information markets, decision markets, idea futures or event derivatives) are open markets where specific outcomes can be predicted using financial incentives. Essentially, they are exchange-traded markets created for the purpose of trading the outcome of events. The market prices can indicate what the crowd thinks the probability of the event is. A prediction market contract trades between 0 and 100%. The most common form of a prediction market is a binary option market, which will expire at the price of 0 or 100%. Prediction markets can be thought of as belonging to the more general concept of crowdsourcing which is specially designed to aggregate information on particular topics of interest. The main purposes of prediction markets are eliciting aggregating beliefs over an unknown future outcome. Traders with different beliefs trade on contracts whose payoffs are related to the unknown future outcome and the market prices of the ...

PredictIt
PredictIt is a New Zealand-based online prediction market that offers exchanges on political and financial events. PredictIt is owned and operated by Victoria University of Wellington with support from Aristotle, Inc. The company's office is located in Washington, D.C. The market was initially launched on 3 November 2014. History PredictIt was first launched on 3 November 2014. By March 2016, the website had approximately 29,000 active traders. The nonprofit educational project of the Victoria University of Wellington, New Zealand, "had to work around federal laws that prohibit online gambling and govern commodity futures trading." During the 2016 United States elections, PredictIt, along with other prediction market websites, received attention from various media outlets. Trading format PredictIt uses a continuous double auction to sell shares for each event in its markets, meaning that for every person who predicts that an event will take place, there must be another person w ...

Scoring Rule
In decision theory, a scoring rule provides a summary measure for the evaluation of probabilistic predictions or forecasts. It is applicable to tasks in which predictions assign probabilities to events, i.e. one issues a probability distribution F as prediction. This includes probabilistic classification of a set of mutually exclusive outcomes or classes. On the other side, a scoring function provides a summary measure for the evaluation of point predictions, i.e. one predicts a property or functional T(F), like the expectation or the median. Scoring rules and scoring functions can be thought of as "cost function" or " loss function". They are evaluated as empirical mean of a given sample, simply called score. Scores of different predictions or models can then be compared to conclude which model is best. If a cost is levied in proportion to a proper scoring rule, the minimal expected cost corresponds to reporting the true set of probabilities. Proper scoring rules are used i ...

Predictive Analytics
Predictive analytics encompasses a variety of statistical techniques from data mining, predictive modeling, and machine learning that analyze current and historical facts to make predictions about future or otherwise unknown events. In business, predictive models exploit patterns found in historical and transactional data to identify risks and opportunities. Models capture relationships among many factors to allow assessment of risk or potential associated with a particular set of conditions, guiding decision-making for candidate transactions. The defining functional effect of these technical approaches is that predictive analytics provides a predictive score (probability) for each individual (customer, employee, healthcare patient, product SKU, vehicle, component, machine, or other organizational unit) in order to determine, inform, or influence organizational processes that pertain across large numbers of individuals, such as in marketing, credit risk assessment, fraud detecti ...

Futarchy
Futarchy is a form of government proposed by economist Robin Hanson, in which elected officials define measures of national wellbeing, and prediction markets are used to determine which policies will have the most positive effect. It was named by ''The New York Times'' as a buzzword of 2008. The idea of futarchy was later introduced in the context of blockchains and The DAO (organization), the DAO bringing it closer to an actual implementation. Criticisms Economist Tyler Cowen said I would bet against the future of futarchy, or its likelihood of succeeding were it in place. Robin says "vote on values, bet on beliefs", but I don't think values and beliefs can be so easily separated. References External links * Forms of government {{constitutional-law-stub ...

Bankruptcy Of FTX
The bankruptcy of FTX is the ongoing liquidation of Bahamas-based cryptocurrency exchange FTX, beginning in November 2022. The collapse of FTX, caused by a liquidity crisis of the company's token, FTT, served as the impetus for its bankruptcy. Prior to its collapse, FTX was the third-largest cryptocurrency exchange by volume and had over one million users. On 2 November 2022, ''CoinDesk'' published an article stating that Alameda Research, a trading firm affiliated with FTX and owned by FTX chief executive Sam Bankman-Fried, held a significant amount of FTX's exchange token, FTT. Following the allegations, Binance—a competing cryptocurrency exchange and a prior investor in FTX—announced it would sell its FTT, leading the market price of the token to crash. The move also triggered a spike in withdrawals from FTX, causing the exchange to freeze withdrawals and creating a liquidity crisis. On 8 November, Binance signed an offer to acquire FTX, but then withdrew the offer. On 11 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Effective Altruism
Effective altruism is a philosophical and social movement that advocates "using evidence and reason to figure out how to benefit others as much as possible, and taking action on that basis". People who pursue the goals of effective altruism, called , often choose careers based on the amount of good that the career achieves while donating to charities based on maximising impact. The movement developed during the 2000s, and the name was coined in 2011. Prominent philosophers influential to the movement include Peter Singer, Toby Ord, and William MacAskill. Several books and many articles about the movement have since been published, and the Effective Altruism Global conference has been held since 2013. As of 2022, several billion dollars have been committed to effective altruist causes. Popular cause priorities within effective altruism include global health and development, social inequality, animal welfare, and risks to the survival of humanity over the long-term future. Eff ...

Privately Held Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or Over-the-counter (finance), over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their public company, publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''. In 2005, using a substantially smaller pool size (22.7%) for comparison, the 339 companies on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santa Cruz, California
Santa Cruz (Spanish for "Holy Cross") is the county seat and largest city of Santa Cruz County, in Northern California. As of the 2020 census, the city population was 62,956. Situated on the northern edge of Monterey Bay, Santa Cruz is a popular tourist destination, owing to its beaches, surf culture, and historic landmarks. Santa Cruz was founded by the Spanish in 1791, when Fermín de Lasuén established Mission Santa Cruz. Soon after, a settlement grew up near the mission called Branciforte, which came to be known across Alta California for its lawlessness. With the Mexican secularization of the Californian missions in 1833, the former mission was divided and granted as rancho grants. Following the American Conquest of California, Santa Cruz eventually incorporated as a city in 1866. The creation of the Santa Cruz Beach Boardwalk in 1907 solidified the city's status as a seaside resort community, while the establishment of the University of California, Santa Cruz in 1 ...
