This study extends research in the sports gaming literature by examining the efficiency of betting markets related to preseason professional sporting events. Using NFL (1995–2014) and NBA (2005–2014) data from preseason games, we examine the pricing efficiency of point spreads in these markets and consider evidence of systematic mispricing. Findings suggest point spreads are too large in these situations, providing a profitable betting opportunity for those willing to systematically wager on underdogs. Similar findings are not seen within the context of NFL or NBA regular seasons. These findings are more pronounced as preseason point spreads become larger. Further stratification by week of the NFL preseason demonstrates that underdogs discontinue their superior performance for the one week (Week 3) in which clubs tend to expel a higher level of effort.  相似文献

We demonstrate that there is a considerable variation in bookmaker margins across matches, time and bookmakers. Our results imply that using match, tournament and players’ characteristics explains the variations in margins hence, they can be helpful in managing intermediation cost in a market of state-contingent assets: fixed-odds betting markets. We also provide evidence that bookmakers protect themselves by increasing odds on the favourite player, thus attracting more bettors to the favourite player, while deterring bettors from betting on the underdog by reducing the odds. By that process, bookmakers are possibly sacrificing a portion of their margin.  相似文献

We test for the existence of Favourite-Longshot Bias (FLB) in tennis betting exchanges. Despite these being order-driven markets, with no direct participation from bookmakers, we have found very similar results to those obtained by Lahvi?ka (2014) for bookmakers’ betting markets: the bias is stronger in matches between lower-ranked players, in later round matches and in high profile tournaments. This suggests that bookmakers’ adjustments to respond to informed betting are not the main driver of FLB. The varying magnitude of the bias across different types of event in the main market also weakens arguments linking FLB to gamblers’ risk preferences, and suggests the need to consider the microstructure features of the market together with the cognitive biases highlighted in the behavioural finance literature.  相似文献

This paper verifies the existence of the favourite‐longshot bias in a variety of sports betting markets where odds are set by bookmakers, but the precise pattern of the bias is not identical. Evidence is found to support a central prediction of the Shin (1993) model, which asserts that bookmakers are impelled to create a bias in their odds because of the presence of insider traders: that margins increase with the number of competitors.  相似文献

This paper critically examines appropriateness of the nonstandard profit function (NSPF) as a tool for measuring profit efficiency. We show that there are some fundamental problems with the NSPF approach, the way it is currently specified and estimated. This is true irrespective of whether technical inefficiency is included or not. Instead of estimating profit efficiency directly from the NSPF, we suggest alternative specifications and recommend using the cost function approach and deriving profit efficiency therefrom. Data from US banks are used to estimate the cost function and the NSPF. Results from alternative specifications are then compared and analyzed.

Despite its prominence in the economic literature, our knowledge regarding the role of game outcome uncertainty (GOU) in spectator decision‐making is fairly limited. Even worse, studies testing the uncertainty of outcome hypothesis (UOH) by exploring TV demand for European football have further intensified the original ambiguity. In this paper, we revisit the role of GOU in spectator decision‐making by testing the UOH with regard to two different sporting products: (1) domestic league and (2) knockout tournament games. Analyzing TV demand for almost 1,500 German football games, we find support for the UOH in league, though not in knockout tournament games.  相似文献

This paper investigates the development from 1991 to 1994 of the Warsaw Stock Exchange, which opened on April 16th, 1991. An overview is presented focusing first on the deepening of the equity market, with a still limited but increasing number of listed companies, and then on the high trading activity and price dynamics with their impressive outburst in 1993. Three important dimensions are thereafter analyzed: the relevance of organizational and regulatory choices, the degree of market inefficiency and the origin of the discrepancy between IPO prices and first quoted market prices. Concluding remarks concentrate on the market's ability to fulfil its fundamental tasks.  相似文献

This paper studies cyclic patterns in the Slovene economy with spectral analysis. It examines if the transition in Slovenia was marked by a statistically significant movement of aggregate economic activity, which corresponds to the definition of business cycle proposed by Mitchell and Burns (1946). It finds that in the period 1992–2000 a statistically significant cyclic component is present. The cyclic component oscillates with the frequency of 33.3 months. The results obtained in this paper suggest, that in the observed period two full-length cycles can be identified.  相似文献

在现实经济活动中特别是在资本市场投资中,人们对将来的情况很难准确地预测到,他们所知道的最多只不过是在未来各种各样的收益状况下所可能产生的结果.也就是说,未来经济活动特别是资本市场投资活动具有不确定性.由于不确定性的预期的作用和影响,在不确定性条件下的资本市场投资预期收益模型与在确定性条件下的收益模型存在着一定的偏差.只有减少人们对经济不确定性的预期,才能使资本市场投资需求旺盛.  相似文献

The effect of market uncertainty on a country’s currency, while widely recognized, is either omitted from mainstream models or addressed using low-frequency series, which are typically subject to aggregation bias and substantial lags. In this article, we propose a new mixed-data sampling (MIDAS) modelling framework that enables us to incorporate the asymmetric daily effects of market uncertainty in a conventional monthly error correction model. We achieve this by proxying market uncertainty via the value of a ‘safe haven’ asset (gold) that investors reallocate towards in the face of heightened market risk. We apply the model to the Iranian black-market exchange rate, using a mix of the daily price of gold (28 June 2010–19 August 2018) and monthly data (July 2010-July 2018) on relative prices. Our results indicate that purchasing power parity (PPP) holds despite the recent unprecedented depreciations in the Iranian currency arising from several rounds of international sanctions. We also find that increased uncertainty can lead to instantaneous and substantial depreciations, whereas stabilization back towards the PPP path is much more sluggish.  相似文献

This study measures financial uncertainty for two classes of alternative financial assets (Dow Jones Islamic and Dow Jones Sustainability Indexes) and the conventional US stock market (Dow Jones Industrial Index) for the period of 1999–2017, using an asymmetric exponential GARCH model. Using an ARDL model, we propose an intertemporal dynamic analysis of uncertainty for Islamic and socially responsible stock markets. Our findings show that, first, conventional and ethical investments present high comparable levels of uncertainty for which the dynamics is time-varying. Second, uncertainty in the conventional US stock market has a significant and positive effect on the uncertainty in alternative stock markets. Thus, uncertainty characterizes conventional and ethical stock markets both in the short and long terms. In particular, while the short-term uncertainty of ethical markets might be associated with their characteristics, the long-term aspect of uncertainty for ethical funds is rather associated with the effect of the conventional stock market environment. Although these findings show mean-reversion and uncertainty spillovers from the alternative stock markets to the conventional US one, they suggest lack of safety and certainty for investments in ethic markets, which remain fragile and closely dependent on the conventional market.  相似文献

Summary. This paper reexamines the condition (1 + n), which Zilcha (1991) presents as a necessary and sufficient condition for dynamic inefficiency of stationary allocations in overlapping generation models with stochastic production. We show that this condition is necessary but not sufficient for a stationary allocation to be dynamically inefficient by Zilchas definition. We also show that there is a narrow but widely studied class of specifications in which the Zilcha test is both necessary and sufficient for dynamic inefficiency of stationary competitive equilibrium allocations. Outside this class, however, counterexamples can be constructed relatively easily.Received: 30 September 2002, Revised: 13 August 2004, JEL Classification Numbers: D51, D90, E13, E22.

This study considers a vertical structure model in which an upstream state-owned enterprise (SOE) and a downstream domestic firm compete with a vertically integrated foreign firm (VIFF). We consider the cost-inefficiency of the SOE and examine the entry decisions of a VIFF under downstream subsidization. We find that without upstream privatization, the VIFF's entry decision might not be socially desirable unless it enters both markets and the cost inefficiency is intermediate. Additionally, a policy to reduce the cost inefficiency might cause a drastic welfare increase or loss when the VIFF changes its entry decision. We then examine upstream privatization and show that a substantial improvement in cost efficiency can increase welfare with privatization. When the SOE maximizes welfare, however, lesser (greater) cost efficiency improvement is necessary to increase welfare with privatization if the ex-ante cost inefficiency is high (low).  相似文献

The analysis of stadium attendance demand has a long tradition in the economic literature. However, despite its evident merits, this previous research has been critiqued at several levels, in particular for relying on a suboptimal demand proxy, i.e. published attendance data. In this short note, we address these shortcomings by exploring a highly unique data set containing official information on spectators’ decisions of whether or not to physically attend 704 German football Bundesliga games played between August 2014 and January 2017.  相似文献

Existing models in the parimutuel betting literature typically explain betting data by either assuming a single, representative bettor with certain risk preferences or by assuming that a number of risk neutral bettors compete strategically within a game theoretic framework. We construct a theoretical framework of parimutuel markets in which we model both strategic interaction and individual bettor risk preferences, distinguishing between sophisticated insiders and recreational outsiders. We solve this model analytically for the optimal insider betting amount in a static symmetric Nash equilibrium. A new data set of 126 million individual horse race bets in New Zealand from 2006 to 2014 allows us to calibrate the model. We find that insiders (those betting $100 or more) outperform outsiders by 7.5% in terms of realized returns. The best fit of the model to the data is obtained when insiders are assumed to be risk neutral and to have an information advantage of 0.08 in probability terms. This finding provides empirical support for the common assumption of risk neutrality in strategic interaction models of parimutuel betting.  相似文献

Past research has demonstrated that bettors believe positive momentum carries over from contest to contest. This article examines whether there is any empirical support for this belief by testing for the presence of across-contest momentum effects in college football. We characterize momentum in multiple fashions and after controlling for between-team heterogeneity find no evidence that systematic relationships exist between the degree of momentum a team enters a contest with and the outcome of that contest. From a wagering market perspective, this indicates that there is no statistically significant advantage to betting on teams perceived to possess positive momentum. Our results also suggest that the combination of the opening betting line set by odds makers and the subsequent market movement of that line does not systematically overreact to teams on streaks.  相似文献

This paper analyzes the effects of regulatory uncertainty regarding labor costs on investment in a liberalized market. We distinguish between the external investment margin (market entry) and the internal investment margin (technology), and establish that regulatory uncertainty affects these margins differently, encouraging market entry, but discouraging technological investment. As a consequence, the impact of regulatory uncertainty on competition in liberalized markets is a combination of these two countervailing forces.  相似文献

Based on a unique composite dataset measuring heterogeneous sports participation, labour market outcomes and local facilities provision, this article examines for the first time the association between different types of sports participation and employment and earnings in England. Clear associations between labour market outcomes and sports participation are established through matching estimation while controlling for some important confounding factors. The results, which are supplemented and supported by a formal sensitivity analysis, suggest a link between different types of sports participation to initial access to employment and then higher income opportunities with ageing. However, these vary between the genders and across sports. Specifically, the results suggest that team sports contribute most to employability, but that this varies by age across genders and that outdoor activities contribute most towards higher incomes.  相似文献

Rottenberg’s uncertainty of outcome hypothesis is about preferences that can vary across fans and sports. We provide the first evidence of the empirical power of the hypothesis in the Korean Professional Baseball League (KPBL). In a panel data set, team-level aggregation over years shows that fans of this league attend in ways consistent with the hypothesis at the level of game uncertainty and consecutive season uncertainty, but only the first is statistically significant. KPBL fans appear to just be looking for a good game. This is consistent with the nearly complete concentration of post-season participation among a very few teams outside of the major population centre in Seoul and a lack of local team identification among KPBL fans. Our work adds to the diversity of league structures in the competitive balance literature since talent levels in KPBL are the result of parent company advertising choices rather than geographic identification. There are research questions and a policy implication.  相似文献
