This paper examines the relationship between product innovation and the success of price collusion using novel laboratory experiments. Average market prices in low innovation (LO) experiments are significantly higher than those in high innovation, but otherwise identical experiments. This price difference is attributed to LO experimental subjects' greater common market experience. The data illustrate how collusion can be perceived as the “only way to make it” in LO markets where product innovation is not a viable strategy for increasing profits. They suggest that product homogeneity can be a proximate cause, and product innovation an ultimate cause, of collusion. (JEL L41, L10, C92)  相似文献

We analyse betting behaviour patterns of the visitors of the specialized betting website dedicated to the popular eSports game Counter-Strike: Global Offensive. The reverse favourite-longshot bias is found, which is rather unusual for parimutuel betting markets, where favourite-longshot bias is more common. We define simple betting strategies based on the bets on underdogs and show that these strategies make a sufficiently large positive profit both on the in-sample and out-of-sample datasets, which is a sign of market inefficiency. In matches with popular underdogs, the sentiment bias decreases the market inefficiency caused by the reverse favourite-longshot bias. At the same time, the role of the geographical location of teams in the reverse favourite-longshot bias is only marginal.  相似文献

Do home foreclosures and short sales equally affect neighbors? On average, no‐default homes sell anytime up to 6 months after sales of foreclosed neighbors suffer a cumulative spillover effect of about 10%. Including the market trend, the total effect increases to 40%. Controlling for foreclosure effects, short sales do not produce additional spillover effects. We apply a modified hedonic model to estimate spillover effects on neighbors, using January 2008 to June 2009 home transactions from one of the most impacted housing markets. Our findings apply to severely “thin” markets and may not be true for stable markets. We show that accurate estimates of spillover effects require correcting for the market trend, two types of time and spatial price interdependence, and the endogenous neighborhood price.

We study experimentally the selection into first‐price sealed‐bid auctions for a risky or an ambiguous prospect. Most subjects chose to submit a bid for the risky prospect, leading to thinner markets for the ambiguous prospect. Transaction prices for both prospects were equal although subjects expected the ambiguous markets to be smaller. Evidence of a positive correlation between risk and ambiguity aversion suggests that the ambiguous markets were populated by relatively risk tolerant bidders. A control experiment with selection in a simple choice task shows that subjects correctly anticipate the effects of selection on market size and risk attitudes. (JEL C91, D44, D81)  相似文献

We apply a model of satisficing to oligopoly markets with price competition. Sellers have profit aspirations reflecting their conjectures about their competitors' behavior and search for a price guaranteeing these aspirations. Because it seems implausible that people have detailed priors on the others' actions, we postulate that sellers entertain multiple conjectures to which no probabilities can be assigned. This allows us to propose a theory of “prior‐free” optimality and to examine experimentally whether people comply with it. We find that decision makers have difficulties in making prior‐free optimal choices. Most are content to just satisfice, although ways to aspire to more ambitious profits were obviously available.

This paper investigates the influence of economic news on consumer sentiment, and examines whether “news shocks”—changes in coverage that would not be expected from incoming data on economic fundamentals—have aggregate effects. Using monthly U.S. data and a structural vector autoregression, I find that (1) sentiment is affected by news shocks; (2) after filtering out effects of news shocks, shocks to sentiment still have positive effects on consumer spending; and (3) news shocks influence both spending and unemployment in significant, though transitory ways. These results are consistent with other evidence of a role of nonfundamental factors in aggregate fluctuations. (JEL E21, E32, D12)  相似文献

This paper investigates the impact of the London bombings on attitudes toward ethnic minorities, examining outcomes in housing and labor markets across London boroughs. We use a difference‐in‐differences approach, specifying “treated” boroughs as those with the highest concentration of Asian residents. Our results indicate that house prices in treated boroughs fell by approximately 2% in the 2 years after the bombings relative to other boroughs, with sales declining by almost 6%. Furthermore, we present evidence of a rise in the unemployment rate in treated compared to control boroughs, as well as a rise in racial segregation. (JEL J15, J71, R21)  相似文献

The below comments were originally posted, in shortened form, on the Facebook Broken No More page. We asked the author to revise for ADAW, and he did. He refers to the article “Widespread Use of Medically Assisted Treatment (MAT) Has Not Resulted in Less Overdoses” (and we resisted the almost overwhelming temptation to change “less” to “fewer”). For the article, go to https://www.thefreedommodel.org/suboxone‐has‐not‐reduced‐deaths‐in‐the‐us/ .  相似文献

The full impact of trade costs in segmenting product markets cannot be captured by considering aggregate prices or in the absence of information on the direction of trade. We address this problem by utilizing product‐specific prices, cross‐sectional productivity indices, and bilateral trade flows, allowing us to identify the probable source of any one product. We show that trade costs in the form of transportation and distribution costs are important in determining international price differences and segmenting international markets. Physical distance relative to the origin has a precisely estimated positive impact on international deviations from the Law‐of‐One‐Price that is larger than estimates that do not account for the origin of each product. Based on our benchmark estimates, the price elasticity of distance was around 10% in 1990. (JEL F4)  相似文献

Sports betting advertising has arguably permeated contemporary sport consumption in many countries. Advertisements build narratives that represent situations and characters that normalize betting behaviour and raise public concerns regarding their detrimental effect on vulnerable groups. Adopting a grounded theory approach, the present study examined a British sample of sports betting advertisements (N = 102) from 2014 to 2016. The analysis revealed that individual themes aligned in a single core narrative, constructing a dual persuasive strategy of sports betting advertising: (i) to reduce the perceived risk involved in betting (with themes such as betting with friends, free money offers, humour, or the use of celebrities) while (ii) enhancing the perceived control of bettors (including themes of masculinity and sport knowledge). In addition, new technological features of sports betting platforms (e.g. live in-play betting) were used by advertisers to build narratives in which the ability to predict a sports outcome was overlapped by the ability of bettors to use such platforms, equalizing the ease of betting with the ease of winning. Based on the data analysed, it was concluded that the construction of a magnified idea of control in sports betting advertising is a cause for concern that requires close regulatory scrutiny.  相似文献

This study examines the “culture wars” using the lens of attitudes toward soccer. Despite soccer's increasing popularity in the United States, anti‐soccer rhetoric is fairly common. In his widely read book, How Soccer Explains the World (2004), Foer contends that the “culture wars,” including divisions over soccer, are better explained by reactions to globalization than social class or political ideology. Using data from a survey of Nebraskans, we find that attitudes about cultural globalization are the best predictor of soccer sentiment. Contrary to popular claims about the “culture wars,” most respondents were moderate in their attitudes toward both soccer and globalization.  相似文献

We report an experiment that assesses the effects of alterations in production conditions and product durability on market power in Bertrand‐Edgeworth duopolies. Static equilibrium analysis predicts that advance (rather than “to demand”) production raises prices, but does not affect profits. The further addition of a simple inventory option causes prices to fall and seller earnings to increase. Contrary to these predictions, we observe similar prices in baseline and advance production treatments, but lower profits given advance production. An inventory option reduces both prices and earnings. Results are driven by the treatments' effects on sellers' capacities to tacitly collude. (JEL C9, D4, L4)  相似文献

How do criminals respond to changes in the benefit from committing a successful crime? This question is relevant for understanding the effectiveness of crime‐fighting policies that reduce demand for illegal goods, disrupt black markets, and otherwise eliminate cheaper avenues to illicit gain. However, the literature has not sufficiently addressed this question, partly because finding a reliable measure of crime lucre is difficult. Using proprietary data on cargo theft, I match historical prices of various goods with their thefts and estimate the price elasticity of theft to be 1.225 over a cumulative 7‐month horizon.

An emerging trend in fisheries management allows different groups of harvesters pursuing the same stock, even under the same management plan, to manage their effort using different rules, so long as each group remains within its “catch share” portion of mortality. Thus harvesters in a single fishery, with a single total allowable catch, concurrently must respond strategically to the behavior not only of those being managed as they are but also of those facing incentives of different management. In a novel quasi‐continuous time experimental environment with a contemporaneous price externality, we explore the effort timing behavior of harvesters managed under common pool (CP) management with that of subjects managed with individual quotas (IQ). Consistent with Nash equilibrium, CP‐managed subjects race‐to‐fish, exerting high levels of effort to secure landings but selling at correspondingly low prices. IQ‐managed subjects in the same fishery hold effort back until the CP fishery closes, and use their quota over the balance of the season at a lower weekly landings level, receiving higher prices. After experiencing both management systems, subjects choose to be in a group with IQ by a 3:1 margin. (JEL Q22, Q28, C73)  相似文献

Social media is now used as a forecasting tool by a variety of firms and agencies. But how useful are such data in forecasting outcomes? Can social media add any information to that produced by a prediction/betting market? We source 13.8 million posts from Twitter, and combine them with contemporaneous Betfair betting prices, to forecast the outcomes of English Premier League soccer matches as they unfold. Using a microblogging dictionary to analyze the content of Tweets, we find that the aggregate tone of Tweets contains significant information not in betting prices, particularly in the immediate aftermath of goals and red cards.

We provide the first solid evidence that Chinese superstitious beliefs can have significant effects on house prices in a North American market with a large immigrant population. Using real estate data on close to 117,000 house sales, we find that houses with address number ending in “4” are sold at a 2.2% discount and those ending in “8” are sold at a 2.5% premium in comparison to houses with other addresses. These price effects are found either in neighborhoods with a higher than average percentage of Chinese residents, consistent with cultural preferences, or in repeated transactions, consistent with speculative behavior.

In this paper, we assess the impact of competition, investment, and regulation on prices of mobile services in France. We estimate hedonic price regressions using data on tariff plans offered by the main mobile telecommunications operator in France between May 2011 and December 2014. In this time period, the obtained quality‐adjusted price index decreased by about 42.8% as compared to a decline in weighted average prices without quality‐adjustment of 8.7%. In a second step, we relate the quality‐adjusted prices to a set of competition, investment, and regulation variables and find that the launch of 4G networks by mobile operators was the main driver of price reductions for classic tariffs with commitment. Low‐cost tariffs without commitment which were introduced to pre‐empt the entry of low‐cost competitor declined at the time of entry. Moreover, we find that regulation, which is approximated by the level of mobile termination charges and international roaming price caps for voice and data, has a joint significant impact on quality‐adjusted prices. In percentage terms, competition is responsible for about 23.4% of total price decline and investments in 4G for 56.1%. We conclude that the reduction in quality‐adjusted prices in the last years was largely caused by competition between operators for a new 4G technology and by entry of a fourth low‐cost operator.

Using the data of 20 major Organization for Economic Co‐operation and Development countries over time, this article documents new evidence on real equity and real currency prices: higher real returns in the home equity market relative to its foreign counterparts are generally associated with real home currency depreciation at monthly frequency, but this negative correlation breaks down or even reverses during times of relatively higher aggregate economic uncertainty or volatility. This article also argues that a long‐run risks‐type model with time‐varying liquidity risk in stock markets can provide one plausible explanation for the time‐varying correlation structure.

The hot hand bias is the widely documented bias toward overestimation of positive serial correlation in sequential events. We test for the hot hand bias in a novel real‐world context, the seeding of National Collegiate Athletic Association (NCAA) basketball tournament teams. That is, we examine whether teams that perform relatively well heading into “March Madness” are seeded too high, and/or teams with poor recent performance are seeded too low. The seeds are determined by a 10‐member committee that only has implicit incentives, but these incentives are still substantial as the committee's decisions are highly scrutinized by the media, fans, and other stakeholders. We find that, contra the hot hand bias, the committee underreacts to signals of momentum heading into the NCAA tournament. Various results indicate this behavior can be attributed to both: (1) inattention to relatively detailed information indicating momentum; and (2) under‐appreciation of the predictive value of this information. Betting markets incorporate this information efficiently, but neglect some additional information that is predictive of winning NCAA tournament games but not of beating the spread. We note that the NCAA tournament has been highly popular and lucrative partly due to the “madness” (high frequency of wins by lower‐seeded teams), which the bias we document contributes to, making the persistence of bias less surprising.

We analyze how an artist's death influences the market prices of her works of art. Death has two opposing effects on art prices. By irrevocably restricting the artist's oeuvre, prices, ceteris paribus, increase when the artist dies. On the other hand, an untimely death may well frustrate the collectors' hopes of owning artwork that will, as the artist's career progresses, become generally known and appreciated. By frustrating expected future name recognition, death impacts negatively on art prices. In conjunction, these two channels of influence give rise to a hump‐shaped relationship between age at death and death‐induced price changes. Using transactions from fine art auctions, we show that the empirically identified death effects indeed conform to our theoretical predictions. We derive our results from hedonic art price regressions, making use of a dataset which exceeds the sample size of traditional studies in cultural economics by an order of magnitude.
