Asymmetric timeliness tests of accounting conservatism   总被引:6,自引:1,他引:6  
Recent accounting research employs an asymmetric timeliness measure to test the hypothesis that reported accounting earnings are “conservative.” This research design regresses earnings on stock returns to examine whether “bad” news is incorporated into earnings on a more timely basis than “good” news. We identify properties of the asymmetric timeliness estimation procedure that will result in biases in the test statistics except under very restrictive conditions that are rarely met in typical empirical settings. Using data series that are devoid of asymmetric timeliness in reported earnings, we show how these biases result in evidence consistent with conservatism. We conclude that the biased test statistics inherent in the asymmetric timeliness research design preclude using this method to measure conservatism; that these biases are irresolvable as they originate in the test’s specification; and that studies employing asymmetric timeliness tests cannot be interpreted as providing evidence of conservatism.

Blockchains, a disruptive technology with potentially many applications in modern‐day supply chain (SC) transactions, have not been adequately reflected by theory. Researchers and business managers must understand where and when blockchains’ application may be expected and investigated. The present study clarifies the discussion about blockchain application areas (BAAs) in SC transactions and their relevance for businesses. This study combines the findings from three methodological approaches: an extant literature review, a Delphi study, and a survey of 151 German machinery and equipment sector business managers. The results further our understanding of blockchains’ business opportunities among SC transactions and verify and extend Iansiti and Lakhani’s (Harvard Business Review 2017; 95: 118) blockchain adoption framework. Verified customer reviews and product quality certification are identified as the most relevant blockchain usages in SC transactions. Interestingly, we anticipate the least likely adoption of blockchains to occur for document‐signing processes despite arguments within the literature that suggest otherwise. Two newly identified BAAs—logistics and delivery systems—and token‐curated registries rank among the top four most relevant. The present study’s valuation of BAAs advances theory and will likely affect business strategies by indicating where, when, and why businesses should participate in blockchain networks.  相似文献

It is recognized that the effectiveness of monetary policy in the control of inflation depends critically on the relationship between inflation and the output gap. During booms, inflation is highly sensitive to monetary influences, but during recessions this influence is considerably muted. However, econometric investigation of this phenomenon has mostly focussed on the developed economies. In this article, the shape of the Phillips curve is investigated for Indonesia. Evidence is found of significant nonlinearities in the inflation–output relationship for Indonesia and it is argued that this relationship is best modelled by the capacity-constraint (L-shape) model.  相似文献

The events surrounding the stock price peak of March 2000 are commonly interpreted as the bursting of a technology or Internet bubble, with some researchers pointing out that the pattern could also arise in fundamental models. We inform the debate by studying the long‐run performance of Internet and technology stocks from March 2000 onward. Using calendar‐time regressions, we do not find conclusive evidence of negative abnormal returns. The results are consistent with a new interpretation of the events; namely, the price drop of the early 2000s was not warranted in light of future cash flows and risk.  相似文献

Mexican President Felipe Calderón took office in December 2006. From the outset, his government deployed an aggressive security policy to fight drug trafficking organizations in what became known as the “Mexican Drug War.” The policy earned considerable criticism since a heavy number of unintended casualties resulted from the frontal assault waged against the drug cartels. In this article, we evaluate the effects of the Mexican Drug War on Mexican states’ economic growth. To do so, we study the effects of the rise in the homicide rate and changes in a state-level approximation of the military budget on economic growth. Using dynamic panel data econometrics, we find that while the growth in the number of homicides had negative and significant effects on state GDP growth, state military expenditures aimed at fighting drug trafficking had a positive and significant effect on the per capita economic growth rate.  相似文献

The last 10?years have seen tremendous expansion in biofuels production, particularly in corn ethanol in the United States, at the same time that commodity prices (e.g., corn) have experienced significant spikes. While supporters claim that biofuels are renewable and carbon-friendly, concerns have been raised about their impacts on land use and food prices. This paper analyzes how US crop prices have responded to shocks in acreage supply; these shocks can be thought of as a shock to the residual supply of corn for food. Using a structural vector auto-regression framework, we examine shocks to a crop??s own acreage and to total cropland. This allows us to estimate the effect of dedicating cropland or non-crop farmlands to biofuels feedstock production. A negative shock in own acreage leads to an increase in price for soybeans and corn. Our calculations show that increased corn ethanol production during the boom production year 2006/2007 explains approximately 27% of the experienced corn price rise.  相似文献

The future of the German pay as you go public pension system is dependent on families with children. In contrast to German tax law, there are no child allowances in the social insurance system. As a result, workers with and without children pay the same pension insurance contributions. This article analyses the introduction of a child allowance into the public pension system in Germany. We quantify the fiscal, distributional and behavioural effects of such a reform.  相似文献

This article examines the responsiveness of new housing supply to prices and costs, using the case of Ireland at quarterly frequency from the 1970s, as well as a county-level panel from the 1990s. Across four error-correction specifications, and supported by an instrumental variables approach, we find the estimated elasticity of new housing supply to prices of +0.9 in the baseline, while that of costs is larger in magnitude (−1.9). We present evidence that responsiveness to prices rose after the 1980s, then fell in the 2000s, before rising again and also that elasticities vary at the county level.  相似文献
