The traditional explanation for the usual favourite–longshot bias in gambling is that gamblers are risk-lovers. Conditions are derived under which the bias occurs and it is shown to be consistent with a utility function that has elasticity greater than one in a certain range. With a utility function that displays risk-aversion as well as risk-loving behaviour over its domain, it is demonstrated that the expected return–win probability frontier is not monotonic as has been hitherto tacitly assumed. This provides a consistent explanation for both the usual favourite–longshot bias and also for the few examples where a reverse bias has been observed. Pooled data supports the thesis that the frontier is not completely monotonic but does indeed have a turning point.  相似文献

A Real Estate Price Index for Thin Markets   总被引:1,自引:1,他引:0  
This article examines a time-series-based method for estimating real estate price indexes for markets that have few transactions. The proposed method is more parsimonious than the conventional repeat sale or hedonic methods. Also, it is potentially more accurate and less prone to outliers. It achieves this by linking current transactions to preceding transactions, thereby increasing the set of comparable transactions on which to base the index. My experiments confirm that the time-series price index fares much better in thin markets than a benchmark hedonic index. It remains close to the true index when there are few transactions and it does not have the volatility of the benchmark index. While the time-series-based index developed in this article does better than the benchmark hedonic index, one surprise result is that the hedonic index is itself quite robust in small samples.  相似文献

This study examines the relation between prior Wall Street Journal (WSJ) announcements of possible bankruptcy filings and price reactions to subsequent bankruptcy filings for 336 firms that filed for bankruptcy between 1980 and 1993. Extant research indicates that price reactions to announcements of economic events are inversely related to the amount of surprise in the announcements. Prior WSJ anouncements of possible bankruptcy filings increase the markets a priori assessment of firms' probability of bankruptcy, thereby potentially reducing the surprise in subsequent bankruptcy filings. We hypothesize smaller price reactions to bankruptcy filings for firms where the WSJ previously published an article indicating that the firm may file for bankruptcy. Our results are consistent with this hypothesis. Specifically, we find smaller price reactions to bankruptcy filings for firms with prior WSJ announcements of possible bankruptcy filings. Our results hold after controlling for firm size, probability of bankruptcy, exchange listing, leverage, and predisclosure information.  相似文献

In this paper, I use weekly data from seven emerging nations—four in Latin America and three in Asia—to investigate the extent to which changes in Fed policy interest rates have been transmitted into domestic short‐term interest rates during the 2000s. The results suggest that there is indeed an interest rates “pass‐through” from the Fed to emerging markets. However, the extent of transmission of interest rate shocks is different—in terms of impact, steady state effect, and dynamics—in Latin America and Asia. The results also indicate that capital controls are not an effective tool for isolating emerging countries from global interest rate disturbances. Changes in the slope of the U.S. yield curve, including changes generated by a “twist” policy, affect domestic interest rates in emerging countries. I also provide a detailed case study for Chile.  相似文献

This paper aims to determine the evidence of returns autocorrelation for the main Latin American stock markets, and the influence of the day of the week effect on this phenomenon. Also, we analyze the importance of non-trading periods and their incidence on stock markets returns. We determine a high autocorrelation in most of the stock markets analyzed, both in local and global currency and the day-of-the-week effect on only some of the stock markets. Evidence of correlation between trading periods returns and those of non-trading periods is also found.  相似文献

Sums of Lévy-driven Ornstein–Uhlenbeck processes are appropriate for modelling electricity spot price data. In this paper we present a new estimation method with particular emphasis on capturing the high peaks, which is one of the stylized features of such data. After introducing our method we show it at work for the EEX Phelix Base electricity price index. We also present a small simulation study to demonstrate the performance of our estimation procedure.  相似文献

We analyze contributions of different markets, related by an approximate arbitrage relationship, to price discovery on traded inflation expectations and how it changed during the financial crisis. We use a new high-frequency data-set on inflation-indexed and nominal government bonds as well as inflation swaps to calculate information shares of break-even inflation rates in the euro area and the USA. In the euro area, for maturities up to 5 years new information comes from both the swap and the bond markets. For longer maturities, the swap market provides less and less information in the euro area. In the USA, the bond market dominates the price discovery process for all maturities. The severe financial crisis that spread out in Autumn 2008 drove a wedge between bond and swap break-even inflation rates in both currencies. Price discovery ceased to take place on the swap market. Disruptions coming from the short-end of the market even separated price formation on both segments for maturities of up to 6 years in the USA. Against the backdrop of the most severe financial crisis in decades, contributions to price formation concentrated a lot more on the presumably safest financial instrument: government bonds.  相似文献

We present an analysis of price systems in securities markets with infinitely many time periods and infinitely many uncertain states of the world. A key result is that a Markov price system (MPS) has a unique representation in terms of the returns on a known set of bonds. The result implies that securities prices are the discounted value of dividends, where discount factors are the reciprocal of the returns on a long-horizon discount bond.  相似文献
