Political uncertainty and the 2012 US presidential election: A cointegration study of prediction markets,polls and a stand-out expert

Political uncertainty is increasingly seen as important to financial markets. Particularly US presidential election uncertainty is linked to uncertainty regarding future US macroeconomic policy. But what is the best vehicle to measure political uncertainty? We examine both the cointegration and causal relationships between the Iowa and Intrade presidential futures markets (IOWA, INTRADE), along with the results of election polls (POLLS); as well as published election predictions of Nate Silver (SILVER), who was arguably the most followed political forecaster during the 2012 presidential election season. We document strong evidence that SILVER and the two prediction markets were all highly cointegrated; while POLLS was not. Consistent with the assertion made by others that INTRADE prices were manipulated in 2012 for non-pecuniary reasons, we also evidence that IOWA and SILVER both Granger-caused INTRADE. Our findings are also consistent with previous findings that election markets outperform polls as prediction vehicles. Overall, while confirming that INTRADE, IOWA and SILVER are cointegrated, we note that the three series consistently differed in the degree of optimism in an Obama victor. These results pose important questions for researchers interested in estimating political uncertainty, and assessing the efficacy of prediction markets and their international integration.     

Aggregate earnings and market expectations in United States presidential election prediction markets

This study uses election futures market data to provide the first empirical evidence that aggregate earnings conveys timely “election-relevant” information effecting betting market participants' expectations about the likely outcomes of United States presidential election campaigns. I document that aggregate earnings news is associated with multiple facets of U.S. economic health affecting voter utility. I then use high-frequency data from the Iowa Electronic Political Prediction Market (IEM) to document that aggregate earnings news, including cash flow news, is significantly related to changes in the expected outcomes of U.S. presidential elections and incremental of other measures of economic health.     

Price Rigidity in Turkey: Evidence from Micro Data

In this study we investigate the duration of consumer price spells and price change patterns for Turkey by employing a comprehensive micro price data covering around 6,000 items over four years. In detail, we analyze how long typical price spell lasts and we investigate the size, frequency, distribution and synchronization of price changes. Compared to advanced economies, a higher frequency of price changes is estimated. Findings suggest substantial heterogeneity among sub-groups in terms of frequency and synchronization indicators. The mixed evidence of both state and time-dependent pricing is also relevant for Turkey, an emerging market economy.     

Price Limit Performance: Evidence from the Tokyo Stock Exchange

Price limit advocates claim that price limits decrease stock price volatility, counter overreaction, and do not interfere with trading activity. Conversely, price limit critics claim that price limits cause higher volatility levels on subsequent days (volatility spillover hypothesis), prevent prices from efficiently reaching their equilibrium level (delayed price discovery hypothesis), and interfere with trading due to limitations imposed by price limits (trading interference hypothesis). Empirical research does not provide conclusive support for either positions. We examine the Tokyo Stock Exchange price limit system to test these hypotheses. Our evidence supports all three hypotheses suggesting that price limits may be ineffective.     

Price Discovery without Trading: Evidence from the Nasdaq Preopening

This paper studies Nasdaq market makers' activities during the one and one-half hour preopening period. Price discovery during the preopening is conducted via price signaling as opposed to the auction used to open the NYSE or the continuous market used during trading. In the absence of trades, Nasdaq dealers use crossed and locked inside quotes to signal to other market makers which direction the price should move. Furthermore, we find evidence of price leadership among market makers that bears little resemblance to their IPO\SEO lead underwriter participation.     

Price discrimination in input markets

We analyze the short‐ and long‐run implications of third‐degree price discrimination in input markets. In contrast to the extant literature, which typically assumes that the supplier is an unconstrained monopolist, in our model input prices are constrained by the threat of demand‐side substitution. In our model, the more efficient buyer receives a discount. A ban on price discrimination thus benefits smaller but hurts more efficient, larger firms. It also stifles incentives to invest and innovate. With linear demand, a ban on price discrimination benefits consumers in the short run but reduces consumer surplus in the long run, which is once again the opposite of what is found without the threat of demand‐side substitution.

名义价格幻觉——基于证券分析师目标价格预测的经验证据

本文利用证券分析师发布的股票目标价格预测,为名义价格幻觉提供了能够直接反映心理预期的经验证据。研究发现,证券分析师对低价股未来收益的心理预期显著高于高价股,该行为偏误在规模小、上市时间短、股票波动性大、财务透明度低和无形资产占比高等估值难度更大的股票中表现得更加明显。我们还利用股票送转,对证券分析师是否受到名义价格幻觉的影响做进一步验证,发现由送转引起的与基本面无关的名义价格下降显著提升了证券分析师对股票未来回报的心理预期。进一步研究表明,上述发现并不是因为证券分析师准确预见了低价股和高价股未来有不同的投资机会,也不是为了最大化其供职证券公司的利益而有意迎合投资者。     

Price Discovery without Trading: Evidence from Limit Orders

We analyze the contribution to price discovery of market and limit orders by high‐frequency traders (HFTs) and non‐HFTs. While market orders have a larger individual price impact, limit orders are far more numerous. This results in price discovery occurring predominantly through limit orders. HFTs submit the bulk of limit orders and these limit orders provide most of the price discovery. Submissions of limit orders and their contribution to price discovery fall with volatility due to changes in HFTs’ behavior. Consistent with adverse selection arising from faster reactions to public information, HFTs’ informational advantage is partially explained by public information.     

US presidential elections and implied volatility: The role of political uncertainty

This paper focuses on the effects of political uncertainty and the political process on implied stock market volatility during US presidential election cycles. Using monthly Iowa Electronic Markets data over five elections, we document that stock market uncertainty, as measured by the VIX volatility index, increases along with positive changes in the probability of success of the eventual winner. The association between implied volatility and the election probability of the eventual winner is positive even after controlling for changes in overall election uncertainty. These findings indicate that the presidential election process engenders market anxiety as investors form and revise their expectations regarding future macroeconomic policy.     

Valuation consequences of regulatory changes in revenue recognition: Evidence from advertising barter sales

This study compares the valuation of advertising barter sales recognized under APB Opinion No. 29, relative to transactions recorded under EITF Issue No. 99-17. EITF 99-17 was the FASB's response to the perception that Internet-related firms were overstating revenue. The results indicate an inverse relation between price-to-sales ratios and the amount of advertising barter recorded under APB 29 by e-tailing firms. In contrast, we find no evidence of a discount for similar transactions recognized under EITF 99-17. This change in value relevance is consistent with increased credibility of recorded revenue. These results have implications for revenue recognition practices and accounting regulation.     

Price Interactions in a Sequential Global Market: Evidence from the Cross-listed Stocks

In this paper, we investigate the pattern of dynamic interactions among the prices of those stocks that are cross-listed on the three major stock markets of the world, i.e. New York, London and Tokyo. Major findings are: first, regardless of the nationality of stocks, innovations in the 'home' market returns are always fed into the returns in the 'overseas' markets, with the former causing the latter in the Granger sense. However, innovations in the New York market returns of foreign stocks are fed back into their respective home markets, contributing to the price discovery there. Second, the 'succeeding' overseas market, which operates immediately after the home market, plays a dual-role: it conducts the home market innovations to the next-opening overseas market, as well as adds its own innovations. Third, the exchange rate changes substantially influence the overseas market returns, but not the home market returns. The exchange rates appear to play a role in the transmission mechanism mainly via the inter-market price parity.     

The value-relevance of R&D and advertising expenditures: Evidence from Korea

This study examines the value-relevance of R&D and advertising expenditures of Korean firms, using a regression model based on the Ohlson [Contemp. Account. Res. (1995) 661] equity-valuation framework. Results indicate that R&D expenditures are positively associated with stock price, suggesting that capitalizing R&D expenditures is appropriate. The association is stronger for the portion of R&D expenditures that is capitalized, rather than expensed, suggesting that investors agree with management that the capitalized expenditures represent greater future economic benefits. Investors also appear to interpret fully expensed R&D expenditures as positive net present-value investments, however, suggesting that these expenditure should also be capitalized. Additional results indicate that advertising expenditures are negatively associated with stock price, and the magnitude of this negative association is similar to the association between other expenses and stock price. These findings suggest that investors believe the economic benefits of advertising expenditures expire in the current period, similar to other expenses.     

Product market competition and corporate advertising expenditure: Evidence from a natural experiment

Using the implementation of “Catalogue for the Guidance of Industries for Foreign Investment” in China in 2015 as an exogenous shock, we adopt the difference-in-differences (DIDs) method to explore the relationship between product market competition and corporate advertising expenditure. The result shows that product market competition significantly promotes corporate advertising expenditure, and the result is robust after conducting a series of robustness tests. In addition, we further examine the effects of product market competition on corporate advertising expenditure in firms with different characteristics. The results show that the effect is more pronounced for non-state-owned enterprises, small-scale firms, and high-tech firms. Overall, this paper supports that product market competition plays a vital role in promoting corporate advertising expenditure.     

Performance of Electricity Price Forecasting Models: Evidence from Turkey

In this article, hourly prices of the Turkish Day Ahead Electricity Market are forecasted by using various univariate electricity price models, then the out-of-sample forecasts are compared with each other and the benchmarks. This article has two main contributions to the literature: Firstly, it provides a factorial Analysis of Variance (ANOVA) as a pre-whitening method of the price series and allows one to work with the stationary residuals series. Secondly, it is the first work, which compares the performances of all important statistical univariate forecast models in the Turkish electricity market. Results indicate the importance of the factorial ANOVA application and the SARIMA model’s success under the given conditions.     

Stock Price Distributions and News: Evidence from Index Options

We estimate the shape of the distribution of stock prices using data from options on the underlying asset, and test whether this distribution is distorted in a systematic manner each time a particular news event occurs. In particular we look at the response of the FTSE100 index to market wide announcements of key macroeconomic indicators and policy variables. We show that the whole distribution of stock prices can be distorted on an event day. The shift in distributional shape happens whether the event is characterized as an announcement occurrence or as a measured surprise. We find that larger surprises have proportionately greater impact, and that higher moments are more sensitive to events however characterised.     

Investment,leverage and political risk: Evidence from project-level FDI

Does capital structure influence firms' FDI capital expenditure decisions into countries with varying degrees of political risk? We explore this question using a novel dataset that matches 10,000 unique outward foreign direct investment (OFDI) projects with 1135 distinct U.S. firms over the period 2003–2014. We find that capital expenditures allocated to FDI projects are significantly lower for highly leveraged firms, in particular for firms with low growth opportunities. Firms also commit lower capital amounts to investments located in countries characterized by higher political risk. Furthermore, leverage and political risk interact with one another in determining the financial commitment of the FDI, with leverage exerting a significantly stronger negative effect on capital expenditures in countries where political risk is elevated. Our findings are consistent with the monitoring role of debt in curbing exposure to political risk in multinational firms' foreign operations, and corroborate the disciplinary role of leverage on firms' investment decisions.     

Government ownership and exposure to political uncertainty: Evidence from China

The government of China started its anti-corruption campaign in December 2012. Since then, more than 600 government officials have been investigated. We regard the investigations involving senior officials as signals of increased political uncertainty. Focusing on these events, we study how firms’ exposure to political uncertainty varies with government ownership. It is found that the stock performance of private firms is worse on the event days than in normal times, whereas state-owned enterprises (SOEs) suffer less from the events. Moreover, the event-day effects are not quickly reversed in the post-event periods. Among SOEs, the negative impact of the events also decreases with government ownership. The evidence indicates that government ownership mitigates firms’ exposure to political uncertainty.     

The Price of Correlation Risk: Evidence from Equity Options

We study whether exposure to marketwide correlation shocks affects expected option returns, using data on S&P100 index options, options on all components, and stock returns. We find evidence of priced correlation risk based on prices of index and individual variance risk. A trading strategy exploiting priced correlation risk generates a high alpha and is attractive for CRRA investors without frictions. Correlation risk exposure explains the cross-section of index and individual option returns well. The correlation risk premium cannot be exploited with realistic trading frictions, providing a limits-to-arbitrage interpretation of our finding of a high price of correlation risk.
