While it is commonly accepted that risk preferences differ across individuals, studies that estimate them typically allow for limited heterogeneity. We develop a methodology that allows for richer representation of heterogeneity both within and across utility types characterized by different behavioral features. This enables us to improve individual- and population-level estimates, and to assess the relative importance of loss aversion and probability weighting, and their prevalence in the population. Applying our model to individual sports-betting choices, we find that utility curvature alone does not explain observed choices and, while two-thirds of individuals exhibit loss aversion, all exhibit probability weighting.
虽然人们普遍认为个体的风险偏好不同,但估计它们的研究通常允许有限的异质性。我们开发了一种方法,可以更丰富地表示由不同行为特征表征的效用类型内部和之间的异质性。这使我们能够改进个人和群体水平的估计,并评估损失厌恶和概率加权的相对重要性,以及它们在人群中的流行程度。将我们的模型应用于个人体育博彩选择,我们发现效用曲率本身并不能解释观察到的选择,而且,虽然三分之二的个人表现出损失厌恶,但所有人都表现出概率加权。

The economics of movies (revisited): A decade of literature in review 电影经济学(重访):十年文学回顾
Pub Date : 2021-09-15 DOI: 10.2139/ssrn.3924209
J. McKenzie
Twenty years ago, there were all but a handful of scholarly studies published about the economics of the motion picture industry. Over the first decade of the new millennium, this changed dramatically and many studies began to appear in economics journals and those of cognate disciplines. The following, and most recent, decade has seen this trend continue and the literature on the `economics of movies' has well and truly matured. While economics and marketing disciplines still generate the most output, newer data-orientated disciplines have increasingly turned their attention towards the industry and its abundance of rich and relatively-accessible data. This survey endeavours to concisely but comprehensively review recent literature related to this eternally fascinating industry.
20年前,关于电影行业经济学的学术研究几乎寥寥无几。在新千年的第一个十年里,这种情况发生了巨大变化,许多研究开始出现在经济学期刊和相关学科的期刊上。在接下来的十年里,也就是最近的十年里,这一趋势一直在继续,关于“电影经济学”的文献也真正成熟了。虽然经济学和市场营销学科仍然产生最多的产出,但新的数据导向学科越来越多地将注意力转向该行业及其丰富且相对可访问的数据。本调查力求简洁而全面地回顾与这个永恒迷人的行业有关的最新文献。

Does Industry Classification Matter in IT Business Value Research? 行业分类在IT业务价值研究中重要吗?
Pub Date : 2021-09-08 DOI: 10.2139/ssrn.3919658
Duane B. Kennedy, Byron Y. Song, Theophanis C. Stratopoulos
Studies which examine the effect of IT on firm performance make the implicit assumption that the choice of industry classification (e.g., SIC instead of NAICS) and the level of aggregation (e.g., 2-digit SIC instead of 4-digit SIC) is unlikely to affect the results. Given that practically none of the studies in our literature review has tested the robustness of their results to an alternative industry classification method, we do not know whether this choice matters (i.e., we don’t know whether the evidence generated from this stream of research is robust). To answer this question, we replicated three studies (Bharadwaj 2000; Chae et al. 2014; Santhanam and Hartono 2003) and found that results are likely to differ if we change the classification method and/or the level of aggregation within a given industry classification method. We encourage IT researchers to replicate prior studies to assess the sensitivity of their results to such choices as well as encouraging future studies to consider implementing robustness checks. The need to consider such robustness checks spans all fields (e.g., accounting, strategic management, and marketing) that use statistical analysis which requires control for role of industry.
检验信息技术对企业绩效影响的研究隐含了一个假设,即行业分类的选择(例如,使用SIC而不是NAICS)和聚合水平(例如,使用2位数的SIC而不是4位数的SIC)不太可能影响结果。鉴于我们的文献综述中几乎没有一项研究对另一种行业分类方法的结果进行了稳健性测试,我们不知道这种选择是否重要(即,我们不知道从这一研究流中产生的证据是否可靠)。为了回答这个问题,我们重复了三项研究(Bharadwaj 2000;Chae et al. 2014;Santhanam and Hartono 2003),并发现如果我们改变分类方法和/或给定行业分类方法内的聚合水平,结果可能会有所不同。我们鼓励IT研究人员重复先前的研究,以评估其结果对这些选择的敏感性,并鼓励未来的研究考虑实施稳健性检查。考虑这种稳健性检查的需要跨越所有使用统计分析的领域(例如,会计,战略管理和市场营销),这需要对行业角色进行控制。

A Simple Method to Estimate Discrete-type Random Coefficients Logit Models 估计离散型随机系数Logit模型的一种简单方法
Pub Date : 2021-09-01 DOI: 10.2139/ssrn.3729184
Naoshi Doi
This paper proposes a new method for estimating random coefficients logit models using aggregate data. The method is applicable for models with discrete-type heterogeneity in consumer tastes when additional data on the total sales for each consumer type are available. The type-level data do not have to be divided by product. The method analytically obtains the value of the econometric error term and thus does not require numerical calculations, such as the contraction mapping established by Berry, Levinsohn, and Pakes (1995). Consequently, the method no longer suffers from problems due to numerical errors in the contraction mapping, including lack of convergence and incorrect parameter estimates. Moreover, the computation time is drastically reduced.
本文提出了一种利用聚合数据估计随机系数logit模型的新方法。当每种消费者类型的总销售额的附加数据可用时,该方法适用于具有离散型消费者口味异质性的模型。类型级数据不必除以乘积。该方法可以解析地获得计量误差项的值,因此不需要数值计算,例如Berry, Levinsohn, and Pakes(1995)建立的收缩映射。因此,该方法不再遭受由于收缩映射中的数值误差造成的问题,包括缺乏收敛性和不正确的参数估计。而且,大大减少了计算时间。

Intermittent versus Dispatchable Power Sources: An Integrated Competitive Assessment 间歇性与可调度电源:综合竞争评估
Pub Date : 2021-07-30 DOI: 10.2139/ssrn.3897672
Gunther Glenk, S. Reichelstein
The cost and revenue earnings potential of alternative power generation sources has shifted considerably in recent years. Here we introduce the concept of Levelized Profit Margins (LPM) to capture the changing unit economics of both intermittent and dispatchable generation technologies. We apply this framework in the context of the California and Texas wholesale power markets. Our LPM estimates indicate that solar photovoltaic and wind power have both substantially improved their competitive position over the years 2012–2019, primarily due to falling life-cycle costs of production. In California, these gains far outweigh an emerging “cannibalization” trend that results from substantial additions of solar power having made energy less valuable in the middle of the day. We also find the competitiveness of natural gas power plants to have either improved or held steady. For this generation technology, declining capacity utilization rates have effectively been counterbalanced by a “dispatchability price premium” that reflects the growing market share of intermittent renewables.
近年来,替代发电资源的成本和收益潜力发生了很大变化。在这里,我们引入了平准化利润率(LPM)的概念,以捕捉间歇发电和可调度发电技术不断变化的单位经济。我们将此框架应用于加利福尼亚州和德克萨斯州的批发电力市场。我们的LPM估计表明,在2012-2019年期间,太阳能光伏发电和风能发电的竞争地位都大幅提高,主要原因是生产生命周期成本下降。在加州,这些收益远远超过了正在出现的“同类相食”趋势,这种趋势是由于大量增加的太阳能发电使能源在中午变得不那么值钱。我们还发现天然气发电厂的竞争力有所提高或保持稳定。对于这种发电技术,“可调度价格溢价”有效地抵消了不断下降的产能利用率,这反映了间歇性可再生能源不断增长的市场份额。

Retail Marketing Industry Comeback Post Pandemic 大流行后零售营销行业卷土重来
Pub Date : 2021-07-23 DOI: 10.2139/ssrn.3895331
Stephanie Austin-Campbell
The retail industry has had a topsy-turvy journey in the past decade. Shoppers have developed a fondness for online shopping and two-day shipping, and this has caused a serious downfall to many retail stores already. Add to that, the global pandemic that encapsulated the entire world for a little over a year, and many retail businesses, that were already in trouble, were never able to recover from the devastation.
在过去的十年里,零售业经历了一段颠倒的旅程。消费者已经对网上购物和两天送达产生了兴趣,这已经导致许多零售商店严重倒闭。此外,全球大流行笼罩了整个世界一年多一点的时间,许多已经陷入困境的零售企业再也无法从这场灾难中恢复过来。

Buyers’ Cartels: Prevalence and Undercharges 买家卡特尔:盛行与低收费
Pub Date : 2021-06-01 DOI: 10.2139/ssrn.3883691
J. Connor
This article supplements information on 24 U.S. domestic buyers’ cartels cited in a 2010 book by Blair and Harrison by assembling and analyzing a sample of 49 episodes of buyers’ cartels that have international membership or multi-jurisdictional price effects. It appears that such cartels comprise less than 8 percent of the total, that they are clustered in primary-products and services industries, that they employ bid rigging conduct to a greater extent than sellers’ cartels, and that undercharges average close to 20 percent of the but-for price. These quantitative characteristics are supplemented by sketches of the conduct and prosecutions of a few of the better-documented cases of buyers’ cartels.
本文对布莱尔和哈里森在2010年出版的一本书中引用的24个美国国内买家卡特尔的信息进行了补充,收集并分析了49个具有国际会员资格或多司法管辖区价格效应的买家卡特尔的样本。这类卡特尔占总数的比例似乎不到8%,它们集中在初级产品和服务行业,它们采用的串通投标行为比卖方卡特尔的程度更大,并且平均低收接近实际价格的20%。除了这些数量特征外,还对一些记录较好的买方卡特尔案件的行为和起诉进行了概述。

Weathering Distress: Corporate Bankruptcy and Bank Competition 渡过困境:企业破产和银行竞争
Pub Date : 2021-05-28 DOI: 10.2139/ssrn.3002938
Jess Cornaggia, Mahsa S. Kaviani, H. Maleki
This paper examines whether competitive banking markets affect the likelihood that firms file for bankruptcy. We compile large and unique databases of U.S. public and private corporate bankruptcies and find that bank competition significantly reduces firms' filing rates. Chapter 11 and 7 filings both decrease. The results are not concentrated among any specific bankruptcy outcome and are unlikely to be driven by forum shopping. The effects are geographically widespread and driven by distressed firms' improved access to credit. The effects become stronger during economic downturns and in states that host firms with ex-ante higher probabilities of distress.
本文考察了竞争性银行市场是否会影响企业申请破产的可能性。我们编制了美国公共和私人公司破产的大型和独特的数据库,发现银行竞争显著降低了公司的申请率。第11章和第7章的申请都减少了。结果并不集中于任何具体的破产结果,也不太可能受到论坛购物的影响。这种影响在地理上是广泛存在的,并受到陷入困境的公司获得信贷渠道改善的推动。在经济低迷时期,这种影响在那些公司陷入困境的可能性更高的州会变得更强。

Efficiency in the CRO industry, 2010-2019 CRO行业效率,2010-2019
Pub Date : 2021-05-04 DOI: 10.2139/ssrn.3839735
Ricardo F Diaz, B. Sanchez-Robles
Outsourcing to Contract Research Organizations (CROs) has become a widespread practice by pharmaceutical and biotechnological firms seeking to reduce risks and costs associated to the development of new products. This paper analyzes empirically the efficiency of the CROs industry by looking at a sample of firms operating in Europe over the years 2010-2019.

We compute efficiency scores of the firms in the sample by means of DEA non- parametric techniques. Basic results suggest that the sector achieves large levels of average efficiency, amounting to 0.716. Average efficiency increases over time in the time horizon considered. A second stage Tobit estimation implies that big firms exhibit higher levels of efficiency than medium size and small firms because large sizes facilitate the use of state-of-the-art technology for data collection and analysis and the accession to stable commercial alliances. Efficiency is also positively correlated with sound human resource and financial managements, and with a moderate size of the fixed assets held by the firm. These results suggest that more merges and acquisitions are expected in this sector in the near future.
外包给合同研究组织(cro)已经成为制药和生物技术公司寻求降低与新产品开发相关的风险和成本的普遍做法。本文通过研究2010-2019年在欧洲运营的公司样本,实证分析了cro行业的效率。采用DEA非参数技术计算了样本企业的效率得分。基本结果表明,该部门达到了较高的平均效率水平,达到了0.716。在考虑的时间范围内,平均效率随着时间的推移而增加。第二阶段Tobit估计表明,大公司比中型和小型公司表现出更高的效率水平,因为大公司便于使用最先进的技术进行数据收集和分析,并加入稳定的商业联盟。效率还与健全的人力资源和财务管理呈正相关,并与企业持有的固定资产规模适度相关。这些结果表明,在不久的将来,该行业将出现更多的并购。

Book-or-Drive: The Impact of Ridesharing on the Automobile Industry 预约或自驾:拼车对汽车行业的影响
Pub Date : 2021-03-22 DOI: 10.2139/ssrn.3810178

This paper empirically examines the impact of Uber, an online ridesharing platform, on automobile registrations, a sales performance indicator in the traditional, mature automobile industry in the United States. We leverage the sequential entry of Uber in different locations in a natural experiment setting and use the staggered difference-in-differences (DID) econometric model to estimate this impact. Our dataset includes yearly observations of Uber’s entry and automobile registration that span more than 600 counties from 2010 to 2017. The results suggest that Uber’s entry has an overall negative effect on automobile registrations, and this effect sustains for another year after entry. The negative effect manifests significantly for counties with larger values of GDP, population, and population density but can become insignificant for counties with smaller values. Our results are robust to matching, placebo tests, and the consideration of Uber’s endogenous entry decision, and are reinforced by the analysis of Uber’s search intensity on Google.

本文实证检验了在线拼车平台Uber对美国传统成熟汽车行业销售业绩指标——汽车注册量的影响。我们利用Uber在自然实验环境中不同位置的顺序进入,并使用交错差中差(DID)计量经济模型来估计这种影响。我们的数据集包括从2010年到2017年对600多个县的优步进入和汽车注册的年度观察。结果表明,优步的进入对汽车注册总体上有负面影响,这种影响在进入后的一年内仍会持续。对于GDP、人口和人口密度较大的县,这种负面影响显著,而对于GDP、人口和人口密度较小的县,这种负面影响可能不显著。我们的结果对匹配、安慰剂测试和考虑Uber的内生进入决策都是稳健的,并且通过对Uber在谷歌上的搜索强度的分析得到了加强。我们的发现具有重要的管理和政策意义,并有助于越来越多的关于共享经济的社会和经济影响的研究。
{"title":"Book-or-Drive: The Impact of Ridesharing on the Automobile Industry","authors":"Ayush Sengupta, Shu He, Xinxin Li","doi":"10.2139/ssrn.3810178","DOIUrl":"https://doi.org/10.2139/ssrn.3810178","url":null,"abstract":"This paper empirically examines the impact of Uber, an online ridesharing platform, on automobile registrations, a sales performance indicator in the traditional, mature automobile industry in the United States. We leverage the sequential entry of Uber in different locations in a natural experiment setting and use the staggered difference-in-differences (DID) econometric model to estimate this impact. Our dataset includes yearly observations of Uber’s entry and automobile registration that span more than 600 counties from 2010 to 2017. The results suggest that Uber’s entry has an overall negative effect on automobile registrations, and this effect sustains for another year after entry. The negative effect manifests significantly for counties with larger values of GDP, population, and population density but can become insignificant for counties with smaller values. Our results are robust to matching, placebo tests, and the consideration of Uber’s endogenous entry decision, and are reinforced by the analysis of Uber’s search intensity on Google. Our findings have important managerial and policy implications and contribute to the growing stream of research on the social and economic impacts of sharing economy.","PeriodicalId":11837,"journal":{"name":"ERN: Other IO: Empirical Studies of Firms & Markets (Topic)","volume":"107 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81576577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
