Our methodology accommodates average, distributional, and quantile treatment effects under different identifying assumptions including unconfoundedness, local treatment effects, and nonlinear differences-in-differences. The proposed estimators are easy to implement, have close-form representation, are fully data-driven upon estimation of nuisance parameters, and do not rely on parametric distributional assumptions, shape restrictions, or on restricting the potential treatment effect heterogeneity across different subpopulations. These treatment effects results are obtained as a consequence of more general results on two-step Kaplan-Meier estimators that are of independent interest: we provide conditions for applying (i) uniform law of large numbers, (ii) functional central limit theorems, and (iii) we prove the validity of the ordinary nonparametric bootstrap in a two-step estimation procedure where the outcome of interest may be randomly censored.","PeriodicalId":202880,"journal":{"name":"Research Methods & Methodology in Accounting eJournal","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124488194","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}

We find that investors increase their margin debt following upward price movements away from accounting fundamentals, consistent with these investors being extrapolative in aggregate. We also find evidence that margin debt appears to be linked to temporary overpricing in recent periods, as the aggregate ratio of margin debt-to- price is reliably associated with negative future returns since at least 1992. Our results are consistent with the theoretical literature which predicts extrapolative traders provide a destabilizing effect on market prices and help explain why prices diverge from accounting fundamentals.","PeriodicalId":202880,"journal":{"name":"Research Methods & Methodology in Accounting eJournal","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133564987","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}

We then provide a discussion of extant field experiments that touch on important issues in accounting and finance, and we also review areas that have ample opportunities for future field experimental explorations.

It addresses the question of why the volume and quality of international accounting research have grown rapidly in recent years. It begins by asking why we do accounting research and moves on to discuss the reasons for conducting international accounting research. These include: to better understand others (and in the process, to better understand ourselves); to provide more replication options; to exploit differences in national institutional structures when investigating the determinants and effects of institutional variables on accounting; to address some limitations of within-jurisdiction research; and to obtain a wider range of changes to exploit (the paradigm example being the advent of IFRS).

In statistics, a threshold classi.es evidence to balance two types of recognition errors weighted by their respective costs to a decision maker. In accounting recognition standards, a threshold induces firms to respond strategically and thus affects the very distribution of evidence the threshold classi.es. With this strategic effect, the optimal recognition threshold is determined by not only the decision maker’s loss function but also the transaction’s features. We compare the optimal threshold’s properties under the statistical and strategic approaches, provide their respective empirical predictions, and discuss the limitations of using a statistical approach to guide accounting standard setting.","PeriodicalId":202880,"journal":{"name":"Research Methods & Methodology in Accounting eJournal","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133856126","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}

Inefficient regulation and high transaction costs feature high in describing the embryonic stage of Georgia's stock market. This paper, by supplying first-hand empirical evidence on time-series properties of the GeSE firms’ earnings, attempts to consider and explain the limited stock market properties from earnings quality perspective. Statistical tests predicate on the primarily collected financial information of 83 Joint Stock Companies registered at the GeSE. The work covers the years from 2005 to 2013, constituting around 500 firm-year observations. The major finding suggests that reported earnings at the GeSE are poorly persistent and predictable, making it difficult for investors to assess firm value. This is a pervasive phenomenon: Investors are practically unable to estimate firm finances up to a three year horizon. It is further revealed that from the earnings components such as cash-flows from operations and total accruals, the former operates with higher persistence and predictability. Financially pernicious years (2008-2009)’ negative effect on the properties of earnings’ components, as opposed to earnings themselves, is also detected. The findings are robust to time and industry fixed effects.","PeriodicalId":202880,"journal":{"name":"Research Methods & Methodology in Accounting eJournal","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116071710","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}

Decisions regarding scale design can have a potentially profound effect on research findings. Despite this importance, an analysis of extant literature in top accounting journals reveals a wide variety of rating scale compositions. The purpose of this paper is to experimentally investigate the impact of scale characteristics on participants' responses. Two experiments are conducted that manipulate the number of scale points and the corresponding labels to study their influence on the statistical properties of the resultant data. Results suggest that scale design impacts the statistical characteristics of response data and emphasize the importance of labeling all scale points. A scale with all points labeled effectively minimizes response bias, maximizes variance, maximizes power, and minimizes error. This analysis also suggests variance may be maximized when the scale length is set at 7 points.
