Abstract
Using the Iowa Electronic Markets (IEM), this article assesses the political impact of several important events during the fall of 2013: the US government shutdown, the Senate elimination of filibusters for presidential nominations (i.e., the “nuclear option”), and the implementation of the Patient Protection and Affordable Care Act (i.e., ObamaCare). Did these events have meaningful effects on congressional control prospects in the 2014 election? According to IEM price changes, Republican chances fell dramatically when the government shut down, and they did not recover on resolution. Eliminating filibusters had a negative impact on Democratic chances. Various aspects of the ObamaCare rollout and reporting, as well as new announcements that incumbents would not run for reelection, had little effect. In contrast, the budget resolution reinforced the status quo. Overall, political rhetoric does not appear to affect congressional control prospects. Instead, actions matter: deliberate partisan actions of Congress adversely affect the initiating party’s prospects, whereas bipartisan initiatives help the party that initiates the bipartisan effort.

"Prediction markets" are designed specifically to forecast events such as elections. Though election prediction markets have been being conducted for almost twenty years, to date nearly all of the evidence on efficiency compares election eve forecasts with final pre-election polls and actual outcomes. Here, we present evidence that prediction markets outperform polls for longer horizons. We gather national polls for the 1988 through 2004 U.S. Presidential elections and ask whether either the pol...

We study the rationality of learning and the biases in expectations in the Iowa Experimental Markets. Using novel tests developed in (Bossaerts, P., 1996. Martingale restrictions on equilibrium security prices under rational expectations and consistent beliefs. Caltech working paper; Bossaerts, P., 1997. The dynamics of equity prices in fallible markets. Caltech working paper), learning in the Iowa winner-take-all markets is found to be in accordance with the rules of conditional probability (Ba...

Aggregate-level data are used in this analysis to explain the outcomes of Senate elections between 1974 and 1986. Using the individual Senate contest as the unit of analysis permits estimating the relative influence of a wide variety of factors on Senate election results including political characteristics of states, characteristics of the candidates, and national political conditions. Of these factors candidate characteristics had the strongest impact on the outcomes of Senate elections. The im...

Abstract 1. Introduction 1.1. In the older forms of reinsurance, often referred to as “proportional” reinsurance, there is no real problem involved in determining the correct safety loading of premiums. It seems natural, in fact almost obvious, that reinsurance should take place on “original terms”, and that any departure from this procedure would need special justification. The only problem which may be troublesome is to determine the three components of the gross premium, i.e. net premium, saf...
