Money exchange is one of the most common day‐to‐day activities performed by humans in the daily market. This paper presents an approach to money tracking through a blockchain. The proposed approach consists of three main components: serial number localization, serial number recognition, and a blockchain to store all transactions and ownership transfers. The approach was tested with a total of 110 banknotes of different currency types and achieved an average accuracy of 91.17%. We conducted a user study in real‐time with 21 users, and the mean accuracy across all users was 86.42%. Each user gave us feedback on the proposed approach, and most of them welcomed the idea.  相似文献

This paper examines the impact of regulation and earnings management incentives on the evolution of tax effect accounting in Australia. Following the release of the first accounting standard on the issue the method spread roughly equally throughout the mining and industrial sectors. Amendments to the standard, which loosened the recognition criteria for tax loss carry forwards, led to a significant increase in the proportion of companies (particularly industrials) adopting income tax allocation. Subsequent amendments restricting such carry forwards were associated with a significant decline in the proportion of companies allocating tax (particularly miners). We also observe differential financial statement effects between mining and industrial companies and, within both sectors, differential financial statement effects across time. Consistent with the arguments of Leppinus (1977) and Gibson (1984) the adoption of tax effect accounting is, on average, earnings enhancing in the post-DS4 period. However, in the pre-DS4 period, adoption was just as likely to reduce income for industrial companies as it was to increase it. In contrast, adoption was almost uniformly earnings reducing for mining companies. Thus something other than an earnings management hypothesis is needed to explain the voluntary adoption decision of the early (pre-DS4) adopters. We conjecture on the alternatives.  相似文献

Using the CAViaR tool to estimate the value-at-risk (VaR) and the Granger causality risk test to quantify extreme risk spillovers, we propose an extreme risk spillover network for analysing the interconnectedness across financial institutions. We construct extreme risk spillover networks at 1% and 5% risk levels (which we denote 1% and 5% VaR networks) based on the daily returns of 84 publicly listed financial institutions from four sectors—banks, diversified financials, insurance and real estate—during the period 2006–2015. We find that extreme risk spillover networks have a time-lag effect. Both the static and dynamic networks show that on average the real estate and bank sectors are net senders of extreme risk spillovers and the insurance and diversified financials sectors are net recipients, which coheres with the evidence from the recent global financial crisis. The networks during the 2008–2009 financial crisis and the European sovereign debt crisis exhibited distinctive topological features that differed from those in tranquil periods. Our approach supplies new information on the interconnectedness across financial agents that will prove valuable not only to investors and hedge fund managers, but also to regulators and policy-makers.  相似文献

Using a large-scale Deep Learning approach applied to a high-frequency database containing billions of market quotes and transactions for US equities, we uncover nonparametric evidence for the existence of a universal and stationary relation between order flow history and the direction of price moves. The universal price formation model exhibits a remarkably stable out-of-sample accuracy across a wide range of stocks and time periods. Interestingly, these results also hold for stocks which are not part of the training sample, showing that the relations captured by the model are universal and not asset-specific.

The universal model—trained on data from all stocks—outperforms asset-specific models trained on time series of any given stock. This weighs in favor of pooling together financial data from various stocks, rather than designing asset- or sector-specific models, as is currently commonly done. Standard data normalizations based on volatility, price level or average spread, or partitioning the training data into sectors or categories such as large/small tick stocks, do not improve training results. On the other hand, inclusion of price and order flow history over many past observations improves forecast accuracy, indicating that there is path-dependence in price dynamics.  相似文献

In this article, we examine whether social media information affects the price-discovery process for cross-listed companies. Using over 29 million overnight tweets mentioning cross-listed companies, we examine the role of social media for a link between the last periods of trading in the US markets and the first periods in the UK market. Our estimates suggest that the size and content of information flows on social networks support the price-discovery process. The interactions between lagged US stock features and overnight tweets significantly affect stock returns and volatility of cross-listed stocks when the UK market opens. These effects weaken and disappear 1 to 3 hr after the opening of the UK market. We also develop a profitable trading strategy based on overnight social media, and the profits remain economically significant after considering transaction costs.  相似文献

This study explores the controversy between the business and academic perspectives regarding earnings before interest, taxes, depreciation, and amortization (EBITDA). Some authors argue that EBITDA is not useful as an indicator, except for comparing companies within the same sector (Assaf Neto, 2003, McClure, 2006, Stumpp, 2000). On the other hand, the business world strongly uses this type of indicator as a tool to support its decisions (Schmalensee, 1985, Moraes, 2005). This difference in opinions has aroused interest in understanding the reasons for its use and has raised questions regarding the usefulness of EBITDA for comparing companies from both the same and different sectors. By applying Hierarchical Linear Modeling (HLM), the main goal of this research is to observe EBITDA behavior across companies selling goods in Brazil, comparing them within the same sector and across different sectors over time. This research allows for the analysis of the reasons why EBITDA patterns occasionally occur. The results show significant variation in EBITDA among companies across the same sector and across companies from different sectors. On the other hand, our results have shown, nevertheless, that the variability among companies from the same sector was the highest one, raising questions on the actual usefulness of this indicator to compare companies from the same sector.  相似文献

Financial analysts interpret the performance of companies and their securities through an industry lens. Just as an industry approach is critical in financial analysis, it's also critical in helping investors evaluate sustainability performance, since sustainability issues differ from one industry to the next—in large because of differences in how companies use natural and other social resources when bringing their goods and services to market, and how they impact society and the environment in the process. The Sustainability Accounting Standards Board (SASB) was created in 2012 to deliver a full set of sustainability accounting standards that can be used to guide industry‐specific corporate sustainability disclosure to the capital markets. SASB has now issued provisional standards for 79 industries, thereby enabling companies and investors for the first time to identify patterns of sustainability risks and opportunities both across and within industries. Although high‐level issues such as climate change, product safety, and resource intensity and scarcity have material impacts across a variety of sectors, those impacts often vary greatly from one industry to the next. Thus, although the risk may be ubiquitous, it is also differentiated to the point that each industry has its own distinct sustainability profile. Understanding these unique profiles can help companies better manage the issues that are most likely to present material risks to their industries.  相似文献

Abstract:  This paper simultaneously examines, for the first time, the determinants of external audit fees of UK companies drawn from the quoted sector (Main Market, the Alternative Investment Market and Ofex), and the unquoted sector (public and private limited companies). The paper also provides new evidence on the effects of corporate failure and the persistence of the big four and mid-tier auditor premiums across the public and private corporate sectors. After controlling for firm size, audit risk and complexity, we find that quoted and unquoted public limited companies have significantly higher audit fees than their private limited counterparts. Our estimates imply that relative premiums for market/corporate form are as follows: Main Market over AIM, 6.8%; AIM over Ofex, 19.5%; Ofex over unquoted plc, 15.5%; and unquoted plc over private, 16.7%. However, despite indications in prior US research to the contrary, we find no evidence that insolvent firms that failed were charged higher audit fees in the year preceding failure. A positive relationship is also found between audit and consultancy fees – a result that persists using an instrumental variables approach to control for endogeneity.  相似文献

We study the impact of corporate networks on the takeover process. We find that better connected companies are more active bidders. When a bidder and a target have one or more directors in common, the probability that the takeover transaction will be successfully completed augments, and the duration of the negotiations is shorter. Connected targets more frequently accept offers that involve equity. Directors of the target firm (who are not interlocked) have a better chance to be invited to the board of the combined firm in connected M&As. While connections have a clear impact on the takeover strategy and process, we do not find evidence that the market acknowledges connections between bidders and targets as the announcement returns are not statistically different from those bidders and targets which are ex ante not connected.  相似文献

Public private partnerships (PPP) are an established model for most governments internationally to provide infrastructure-based services, using private finance. Typically the public authority will sign a contract with a special purpose vehicle (SPV), which, because of the holistic nature of PPP, in turn sub-contracts the finance, design, construction, maintenance and soft services to companies that are often related to its shareholders. Thus there is a considerable network of linked organisations that together procure and provide the PPP project.While there is an increasing body of research that examines these PPP projects, much of it is interview or case study based so that the evidence is drawn from a small number of interviews or cases in specific sectors. It also focuses on the public sector procurer and the private sector contractor in the network of organisations. Although it has been recognised that the perceptions of the financiers may vary from those of other key PPP players there is much less research that focuses on the financiers.In this paper we report the results of a postal questionnaire survey, administered to 109 providers of senior debt and equity, from which the response rate was just less than 40%. We supplement these findings with a small number of illustrative quotes from interviewees, where the cited quote represents a commonly held view. We used SPSS and Nvivo to analyse the data.The findings show that when assessing PPPs financiers perceive a very wide range of risks as important, and that it is important to them that many of these risks are either insured or allocated to sub-contractors. When considering participating in PPPs, financiers agree that working with familiar partners on familiar projects and in familiar sectors is important, which may raise barriers to entry and undermine competitive processes.  相似文献

This paper looks at the performance record of M&As that took place in the European Union financial industry in the period 1998–2002. First, the paper reports evidence on shareholder returns from the merger. Merger announcements implied positive excess returns to the shareholders of the target company around the date of the announcement, with a slight positive excess-return on the 3-months period prior to announcement. Returns to shareholders of the acquiring firms were essentially zero around announcement. One year after the announcement, excess returns were not significantly different from zero for both targets and acquirers. The paper also provides evidence on changes in the operating performance for the subsample of merges involving banks. M&As usually involved targets with lower operating performance than the average in their sector. The transaction resulted in significant improvements in the target banks performance beginning on average 2 years after the transaction was completed. Return on equity of the target companies increased by an average of 7%, and these firms also experience efficiency improvements.  相似文献

While many countries have adopted International Financial Reporting Standards (IFRS) for private sector enterprises, New Zealand (NZ), Australia and the United Kingdom adopted IFRS for all sectors, including the public sector. This approach is consistent with the concept of sector‐neutral accounting standards that gained wide acceptance in NZ and Australia in the early 1990s. Although a number of studies have assessed the impact of IFRS adoption in the private sector, and the public sector has provided some evidence as to the effects of IFRS adoption on financial statements, the costs of adopting IFRS have not been examined. One measure of cost is the change in audit fees in an IFRS reporting environment. The authors examine the impact of IFRS adoption in the NZ public sector on audit fees and audit effort. They obtained data regarding audit fees and audit effort in the NZ public sector and compared the pre‐adoption year with the first year of adoption for all segments. Their results indicate a substantial increase in audit fees and audit effort in the first year of IFRS adoption for all segments, with some variation across the segments. Two sectors, local authorities and energy companies, have had significant increases in audit fees and audit effort. These findings provide some empirical evidence regarding the cost of transition to IFRS and are of interest to researchers and regulators in countries that are currently considering transitioning to IFRS or IFRS‐based International Public Sector Accounting Standards standards in reporting for the public sector.  相似文献

We provide evidence of a significant relation between diversification and performance in the hedge fund industry. Measuring diversification across four distinct dimensions, we find a significant positive relation between hedge fund performance and diversification across sectors and asset classes. We show that on a risk adjusted basis, hedge funds that diversify across sectors and asset classes outperform other funds by an average of 1.1% per year. However, diversification across styles and geographies exhibits a significant negative association with hedge fund returns. Funds that diversify across styles and geographies underperform other funds by an average of 1% per year. For fund of hedge funds, we find a significant positive relation between performance and diversification across sectors. However, diversifying across asset classes and geographies is found to exhibit a negative relation with fund performance. Finally, we find that the motive to engage in diversification is consistent with managerial incentive structure in the hedge fund industry.  相似文献

This report addresses two key questions for today's top executives: Do acquisitions create value for acquirers? And under what circumstances have acquisitions created the most value for acquiring shareholders?
The authors' analysis of over 1,500 completed deals by non-financial companies in the United States over the past 12 years shows that, at announcement, acquirers' shareholders suffer small losses, on average, in the short term around the initial deal announcement. Over longer intervals, such as one or two years following the announcement of the transaction, acquirers tend to slightly outperform industry peers.
The average or median market response hides tremendous variability in how the market has reacted to individual deals, however. This article provides evidence that the "right" M&A transaction can create substantial value for acquirers. One-quarter of the transactions lead to market-adjusted gains in excess of 5% for the acquirer and oneeighth of the transactions lead to gains in excess of 10% in the short term. However, some deals have also destroyed substantial shareholder value.
Financing structure is a key driver of the stock market reaction. Stock-financed transactions, on average, have a negative stock market reaction, while cash-financed transactions have benefited acquirers in both the short term as well as the long term.
Acquisitions of private companies or assets and units of public companies have consistently generated higher returns for acquirers than purchases of public companies.
Moreover, EPS dilution is not a major driver of how the stock market reacts to a deal. Although "accretive" deals perform slightly better than "dilutive" ones in the short and long run, the difference is small and not statistically significant. Over the long run, acquiring shareholders have benefited the most from deals within the same industry and that avoid targets with relatively optimistic earnings growth projections.  相似文献

This study investigates the use and abuse of graphs in external financial reporting. From an analysis of the annual reports of 240 large UK companies for the year ended 1989 we document the nature and extent of graph usage. The average number of graphs per annual report is 5.9, with 65% of companies graphing at least one key financial variable. Drawing on modern theories of graphical perception we identify selectivity in the use of graphs, and non-compliance with the principles of graph construction, as potential distortions in the communication process. We find that companies with ‘good’ performance are significantly more likely to use financial graphs. Material measurement distortions occur in 30% of these graphs, with the underlying numerical data being exaggerated by an average of 10.7%. We conclude that auditors' and directors' responsibilities in this area should be made more explicit.  相似文献

There is a disconnect in most companies between strategy formulation and strategy execution. On average, 95% of a company's employees are unaware of, or do not understand, its strategy. If employees are unaware of the strategy, they surely cannot help the organization implement it effectively. It doesn't have to be like this. For the past 15 years, the authors have studied companies that achieved performance breakthroughs by adopting the Balanced Scorecard and its associated tools to help them better communicate strategy to their employees and to guide and monitor the execution of that strategy. Some companies, of course, have achieved better, longer-lasting improvements than others. The organizations that have managed to sustain their strategic focus have typically established a new corporate-level unit to oversee all activities related to strategy: an office of strategy management (OS M). The OSM, in effect, acts as the CEO's chief of staff. It coordinates an array of tasks: communicating corporate strategy; ensuring that enterprise-level plans are translated into the plans of the various units and departments; executing strategic initiatives to deliver on the grand design; aligning employees' plans for competency development with strategic objectives; and testing and adapting the strategy to stay abreast of the competition. The OSM does not do all the work, but it facilitates the processes so that strategy is executed in an integrated fashion across the enterprise. Although the companies that Kaplan and Norton studied use the Balanced Scorecard as the framework for their strategy management systems, the authors say the lessons of the OSM are applicable even to companies that do not use it.  相似文献

At the end of 2018, the Sustainability Accounting Standards Board (SASB) released its corporate reporting standards for material environment, social, and governance (ESG) issues. These SASB standards are analogous to FASB's but deal with ESG activities that help the companies create value over the long term and have been endorsed by large asset management firms such as BlackRock. The authors analyze the quality of ESG reporting by the 91 companies that adopted SASB's framework. While the number of such companies is still small, their results are encouraging, an indication of better things to come. Using three measures of effectiveness, Disclosure Topic Compliance Index (DTCI), Financial Relevance Compliance Index (FRCI), and Financial Intensity Compliance Index (FICI), the authors found that most companies are doing a good to very good job of reporting and companies tend to focus on measures with the highest financial relevance. Scores on these three measures were similar across industry sectors except for a few cases where the DTCI score is low. They presented cases of three SASB standard companies: 1) Sunrun, a residential solar panel company that uses some hazardous materials, 2) Suncor, an integrated oil and gas company, and 3) Target, a retail company in a highly competitive industry needing to keep costs low while also managing an extensive supply chain responsibly. These 91 companies have demonstrated that reporting according to SASB standards can be done well. This success should encourage other companies to follow and the authors offer a seven‐step process to adopt SASB standards.  相似文献

We ask what determines the profitability of candlestick trading strategies. Is it the definition of trend and/or the holding strategy that one uses in candlestick charting analysis? To answer this, we systematically consider three definitions of trend and four holding strategies. Applying candlestick trading strategies to the DJIA component data, we find that regardless of which definition of trend is used, eight three-day reversal patterns with a Caginalp–Laurent holding strategy are profitable when we set the transaction cost at 0.5% and after we account for data-snooping bias, while the patterns with a Marshall–Young–Rose holding strategy are not profitable. For sensitivity analysis, we also find that our results are not qualitatively changed on a lower transaction cost of 0.1%, or when we conduct the subsample analyses based on three equal periods and three distinct market conditions. When considering a more volatile market, evidence in favor of candlestick trading strategies is strengthened.  相似文献

Using published data from the top 166 ASX companies and 1244 corporate board members, this paper presents an industry‐level analysis of board structures and member profiles, and assesses them in terms of the ASX (2014, 2003) principles and recommendations. The analysis reveals that the average board size was seven, non‐executive director (NED) representation on boards was 70%, women held 14% of seats on corporate boards, 17% of NEDs were women and 2% of firms had chairperson/CEO duality positions. The Financial, Industrial and Energy sectors consisted of a majority of executive directors from business and the accounting field and NEDs from the engineering field with work experience of 20 to 30 years. A greater degree of diversity in the field of study and previous experience in the same and different sectors was found in relation to board members in the majority of industrial sectors. The analysis reveals that board characteristics such as board size, having a clear majority of NEDs on boards, decreasing trends in chairperson/CEO duality position, board member diversity in terms of qualifications and previous experience in the same and different sectors were largely consistent with the ASX principles and corporate governance practices.  相似文献
