The Iowa Electronic Markets (IEM) are a group of real-money futures markets operated by the University of Iowa's Tippie College of Business. The IEM has been in operation since 1988 and is designed to research the efficiency of markets and the impact of various factors on market outcomes. The markets allow traders to buy and sell contracts based on the outcome of various events, including presidential elections, congressional elections, and economic indicators. The IEM has been used as a tool for predicting the outcomes of elections and other events, with its prices often being cited as a benchmark for predicting the likelihood of different outcomes.
The IEM is based on the concept of a "prediction market," which is a market where participants trade on the outcome of future events. The market prices reflect the collective beliefs of the traders about the likelihood of different outcomes. The IEM uses a real-money format, where traders deposit funds into their accounts and use these funds to buy and sell contracts. This format is designed to incentivize traders to make informed decisions, as they have a financial stake in the outcome of the market. The IEM has been shown to be a highly effective predictor of election outcomes, with its prices often being more accurate than traditional polls.

History of the Iowa Electronic Markets
The IEM was first established in 1988, with the goal of researching the efficiency of markets and the impact of various factors on market outcomes. The market was initially limited to trading on the outcome of the 1988 presidential election, but it has since expanded to include a wide range of events. The IEM has been used to predict the outcomes of numerous elections, including presidential elections, congressional elections, and gubernatorial elections. The market has also been used to predict the outcome of various economic indicators, such as the unemployment rate and the inflation rate.
Operational Mechanics of the IEM
The IEM operates as a real-money futures market, where traders can buy and sell contracts based on the outcome of future events. The market uses a margining system, where traders are required to deposit funds into their accounts in order to trade. The margining system is designed to ensure that traders have a financial stake in the outcome of the market, which incentivizes them to make informed decisions. The IEM also uses a mechanism for settling contracts, where the contracts are settled based on the actual outcome of the event. For example, if a trader buys a contract on the outcome of a presidential election, the contract will be settled based on the actual outcome of the election.
| Event | Prediction Accuracy |
|---|---|
| 2000 Presidential Election | 95.5% |
| 2004 Presidential Election | 92.1% |
| 2008 Presidential Election | 96.2% |
| 2012 Presidential Election | 94.5% |
| 2016 Presidential Election | 91.1% |
Criticisms and Limitations of the IEM
While the IEM has been shown to be a highly effective predictor of election outcomes, it is not without its criticisms and limitations. One of the main criticisms of the IEM is that it is susceptible to manipulation by traders with large amounts of capital. These traders can potentially manipulate the market prices by buying or selling large quantities of contracts, which can impact the accuracy of the market’s predictions. Additionally, the IEM is limited by the number of traders who participate in the market, which can impact the market’s ability to aggregate the collective beliefs of a large number of traders.
Addressing the Criticisms and Limitations
In order to address the criticisms and limitations of the IEM, the market’s operators have implemented a number of measures. For example, the IEM has implemented a mechanism for detecting and preventing manipulation by traders with large amounts of capital. The market also has a mechanism for incentivizing traders to provide accurate predictions, which helps to ensure that the market prices reflect the collective beliefs of a large number of traders. Additionally, the IEM has expanded its operations to include a wider range of events and has increased its marketing efforts to attract more traders to the market.
