If this was a deliberate manipulation effort it failed, however, as the price of the contract rebounded rapidly to its previous level. As more press attention is paid to prediction markets, it is likely that more groups will be motivated to manipulate them. However, in practice, such attempts at manipulation have always proven to be very short lived. In their paper entitled "Information Aggregation and Manipulation in an Experimental Market" ,  Hanson, Oprea and Porter George Mason U , show how attempts at market manipulation can in fact end up increasing the accuracy of the market because they provide that much more profit incentive to bet against the manipulator.
Using real-money prediction market contracts as a form of insurance can also affect the price of the contract. For example, if the election of a leader is perceived as negatively impacting the economy, traders may buy shares of that leader being elected, as a hedge.
These prediction market inaccuracies were especially prevalent during Brexit and the US Presidential Elections. Even until the moment votes were counted, prediction markets leaned heavily on the side of staying in the EU and failed to predict the outcomes of the vote. According to Michael Traugott , a former president of the American Association for Public Opinion Research , the reason for the failure of the prediction markets is due to the influence of manipulation and bias shadowed by mass opinion and public opinion.
Similarly, during the US Presidential Elections, prediction markets failed to predict the outcome, throwing the world into mass shock. Like the Brexit case, information traders were caught in an infinite loop of self-reinforcement once initial odds were measured, leading traders to "use the current prediction odds as an anchor" and seemingly discounting incoming prediction odds completely.
Because online gambling is outlawed in the United States through federal laws and many state laws as well, most prediction markets that target US users operate with "play money" rather than "real money": they are free to play no purchase necessary and usually offer prizes to the best traders as incentives to participate.
Notable exceptions are the Iowa Electronic Markets , which is operated by the University of Iowa under the cover of a no-action letter from the Commodity Futures Trading Commission , and PredictIt , which is operated by Victoria University of Wellington under cover of a similar no-action letter. Some kinds of prediction markets may create controversial incentives. For example, a market predicting the death of a world leader might be quite useful for those whose activities are strongly related to this leader's policies, but it also might turn into an assassination market.
Some prediction websites, sometimes classified as prediction markets, do not involve betting real money but rather add to or subtract from a predictor's reputation points based on the accuracy of a prediction. This incentive system may be better-suited than traditional prediction markets for niche or long-timeline questions. A study found that real-money prediction markets were significantly more accurate than play-money prediction markets for non-sports events.
A combinatorial prediction market is a type of prediction market where participants can make bets on combinations of outcomes. One difficulty of combinatorial prediction markets is that the number of possible combinatorial trades scales exponentially with the number of normal trades. These exponentially large data structures can be too large for a computer to keep track of, so there have been efforts to develop algorithms and rules to make the data more tractable.

Accordingly, to estimate the Mexican financial variables response to the electoral preferences, a VECM model that incorporates the existence of a long-term relationship cointegration is in order, as represented in equations  and  below. In the case of the Canadian financial variables, for which no cointegration relationship was detected, a VAR approach is used, as represented in equations  and . The lag order selection criteria for both models was obtained and is reported below.
However, we implement a one lag basic model in this case too since the values of the criteria are very close, as shown in Table 5. Table 6 shows the output of the estimation of the two VECM models on the Mexican financial variables equations  and . But, except for that, both have the same sign and are statistically significant, i. A positive spread in the expectations of the Democratic candidate winning the election has a positive sign for the IPC equation the stock market rallies , and has a negative sign for the MXNUSD equation the peso exchange rate appreciates relative to the dollar.
Both are significant and their signs match our expectations. Table 7 reports a similar analysis for the Canadian financial variables. This time no cointegrating term was found, hence the equations are modeled as un-restricted VARs. A battery of autocorrelation, heteroscedasticity, normality and ARCH effects are run on the residuals of the previous models to confirm their correct specification, and to make sure that the inference extracted from both VAR and VECM models is correct and reliable.
Jarque-Bera tests show that the residuals are not statistically normal in three of the four cases, mainly due to a high kurtosis the test is not rejected for skewness , as reported in Table 9. This is a stylized fact in financial series. A shock on the exchange rate on itself remains present after ten days and tends to diminish very slowly.
In contrast, the information on the campaign trail was incorporated in a rapid and unbiased way on the Mexican currency and stock market. In practical terms, this regularity was helpful for portfolio managers when establishing their investment strategies.
This active approach led in many cases to traders outperforming the market. Conversely, portfolio managers could take a passive approach when tracking the Canadian index. Second, this study contributes to the debate on whether polls follow bets or vice versa. This finding fully agrees with the reaction time advantages that Duquette et al.
NAFTA was created with the purpose of having a free-trade zone to promote complementarities and impulse economic growth among its three members, Canada, Mexico and the U. Economists, think-tanks, academicians and government authorities should coordinate and develop plans and strategies to achieve that end. Lastly, this study analyzes a quite novel topic, since there are not so many studies about the US presidential election. Empirical results reflected on the ups and downs of the campaign, plus its dramatic outcome, opened a new avenue for future research.

Abstract: This article investigates how the results of the electoral polls and the registration of electronic bets on the outcome of the Presidential election of the United States explain the stock market performance and the currency exchange rates for Canada and Mexico, the other two member countries of NAFTA.
Introduction After the Second World War, the United States achieved the status of the number one economy in the world. Traditional Theories on the Determination of Currency Exchange Rates and Stock Prices of Publicly Traded Firms The number of published studies that attempt to explain how does the determination of currency exchange rates takes place is vast.

A contributing factor for the large size of betting markets is that, before the mids, there were no scientific polls that could aggregate information the way those markets did. Since and untilthe Gallup poll correctly predicted the winner of the USA Presidential elections. As of yesterday, the market had been saying that the election of an Italian pontiff was the single most-likely outcome, with an implied probability of forty-seven per cent. What can be said about scientific polls is that their statistical foundations are still in a process of gradual but consistent improvement and, while no polling service including FiveThirtyEight can claim a flawless record, they are all increasingly scientific and robust, and can produce reasonably good forecasts. Since then, the number of people using the site has plummeted.|
