Risk aversion,public disclosure,and partially informed outsiders

In this paper, we examine the impact of public disclosure and partially informed outsiders on a risk-averse insider’s trading behavior, market efficiency, and market depth. In our model, under disclosure requirements, except for the final auction, market depth is the same at every auction. When informed outsiders are risk-neutral, in contrast to the case of a risk-averse insider with no informed outsiders, the insider is more concerned about the uncertainty about future price risk. When the number of informed outsiders increases, market liquidity improves, and the insider increases the variance of her random component to conceal her trading strategy. However, since the insider is relatively more risk-averse, she pays less attention to doing this on her own. Besides, the order flow provided by informed outsiders and randomly added by the insider injects additional liquidity into the market. When informed outsiders are risk-averse, compared to risk-neutral informed outsiders, an insider is most concerned about trading risks brought by informed outsiders at the beginning of trading. Furthermore, whether the trader is an insider or informed outsider, the more risk-averse trader has lower expected profits. Moreover, outsiders’ greater risk aversion leads to a smaller market depth.     

Insider-controlled Firms in Russia

Privatisation Vouchers in Russia were heavily invested in the holders' own firms. Using data from a recent survey, we show that insider control in firms privatised in 1992-4 through the voucher process (as distinct from the earlier leased buy-out method) is insecure and dependent on managers' support. For employees, investment in insider control appears to have been motivated by employment income insurance rather than expected excess returns on the equity. Managers are predominantly the same individuals as before privatisation and display considerable hostility to outside investors, probably because they fear dismissal should outsiders gain control. Despite insider control, firms are shedding labour quite rapidly through voluntary resignations. Employment dynamics appear to be unrelated to insider equity ownership. This revised version was published online in July 2006 with corrections to the Cover Date.     

Board Composition and Organizational Performance: Two Studies of Insider/outsider Effects

This paper presents two studies that examine the commonly held belief that corporate boards are more likely to have positive effects on organizational performance when composed of outside directors. The first study – a meta-analysis of 63 correlations – indicates that, on average, the greater presence of outsiders is associated with higher performance, but so too is the greater presence of insiders. Instead of providing evidence of a positive outsider effect, these results suggest the existence of a curvilinear homogeneity effect in which performance is enhanced by the greater relative presence of either inside or outside directors. The second study – a hierarchical polynomial regression analysis of data from 259 large US companies – confirms the existence of a curvilinear relationship between insider/outsider composition and performance measured as return on assets.     

Option introduction and insider trading in the NASDAQ/NMS equity market

This paper investigates and supports the hypothesis that insiders have an incentive to shift their informed trading activities when options initially are listed for a firm. Firm size is found to be related to the level of insider trading activity. There is a significant decrease in insider equity-market volume for the smallest third of firms, a significant increase in insider-equity market volume for the middle third of firms, and a significant decrease in insider equity-market volume for the largest third of firms. This supports the hypothesis of a difference in the degree of impact on equity volume upon option introduction based upon firm size. This research provides additional evidence of informed trading activities when option introduction, insider trading, and firm size are considered simultaneously.     

业绩预告下的股份减持与内幕交易——会计稳健性是遏制还是助力？

选取2010—2018年沪深A股上市公司为样本,考察业绩预告发布前后大股东是否存在以及如何利用自身信息优势进行股份减持交易,会计稳健性是否以及如何对该内幕交易产生影响。研究结果表明:与强制性业绩预告相比,自愿性业绩预告披露前后发生大股东减持的概率更高,并且会计稳健性会显著抑制自愿性业绩预告披露前后的大股东减持行为。进一步将业绩预告消息区分为好消息和坏消息之后研究发现:坏消息的利空程度越高,大股东在业绩预告之前进行股份减持的规模越大;或者好消息的利好程度越高,大股东在业绩预告之后减持的规模也越大;稳健的财务信息能够抑制公司在隐匿坏消息方面进行的内幕交易,但会加剧公司在隐匿好消息方面进行的内幕交易。     

Conceptualising the dynamics of employee information and consultation: evidence from the Republic of Ireland

The debate concerning the emerging regulatory environment for employee voice continues apace, in particular the requirements to inform and consult employees as a result of the European Employee Information and Consultation Directive. This article examines the processes used to inform and consult employees across 15 case studies in the Republic of Ireland. It evaluates different voice arrangements using a conceptual framework that seeks to capture the dynamics of different employee voice schemes across union and non‐union companies. The findings suggest that participation is more robust when the channels for information and consultation accommodate both conflictual and cooperative processes. It is shown that robust forms of participation are more likely through processes that facilitate independent representation. The evidence also shows that some employers may devise their own counterbalancing forms of (pseudo) consultation, in an attempt to minimise the impact of regulatory rights for employee voice.     

Filtration enlargement-based time series forecast in view of insider trading

This survey reviews filtration enlargement models in view of insider trading. Although filtration enlargement aptly models insiders' informational advantage, the theoretical results have not attracted the attention of the empiricists, owing mainly to the lack of a bridge transforming the results to testable hypotheses, and/or the absence of econometrics method linking the hypotheses and the data. This survey provides a feasible avenue to estimate insider information and to detect trading from a relatively sophisticated theoretical model, where the dynamics of publicly available data (e.g., stock price) implies insider information before the information is completely digested. We complete the survey with an empirical illustration based on simulated data.     

Achieving a new equilibrium? The stability of cooperative employer–union relationships

The current popularity of ‘partnership’ in workplace industrial relations raises the question of the durability of such arrangements. This article investigates the stability of cooperative employer–union relationships by means of case studies. It analyses perceptions of the experience of negotiation and consultation. Continuing net benefits are reported both by managers and by union representatives in workplaces where cooperative relationships are robust. The benefits come primarily from the informal consultative processes and levels of trust that are engendered. Nonetheless, parties to the relationship, however robust they were, faced substantial challenges to their efforts to diffuse and sustain cooperative working. It is concluded that cooperative relationships are likely to be stable where employers wish to maintain an independent employee voice, especially where workplace union density remains relatively high.     

Growth opportunities,corporate governance and the market value of multinational joint ventures

This paper examines whether differences in investment opportunities and corporate ownership structure can explain the disparate findings of other researchers with regard to the market's price reaction to the announcement of international joint ventures. We study a sample of 320 joint ventures announced during the period 1987–92. The sample joint ventures involve at least one US partner and one or more international partners from emerging economies (former communist countries in Eastern Europe and China), as well as industrialized G7 countries. We find that international joint ventures are on average wealth creating when the foreign partner comes from an emerging economy but are wealth neutral when the partner is from an industrialized country. This finding supports the investment opportunity set hypothesis. However, we do not find support for the shareholder-management alignment hypothesis in that higher insider holdings or a greater level of outsiders on the board for the US partner will lead to joint venture investments that are more highly valued by investors, other things remaining the same. © 1998 John Wiley & Sons, Ltd.     

The Impact of Horizontal Mergers on Rivals: Gains to Being Left Outside a Merger

It is commonly perceived that firms do not want to be outsiders to a merger between competitor firms. We instead argue that it is beneficial to be a non-merging rival firm to a large horizontal merger. Using a sample of mergers with expert identification of relevant rivals and the event-study methodology, we find rivals generally experience positive abnormal returns at the merger announcement date. We also find that the stock reaction of rivals to merger events is not sensitive to merger waves; hence, 'future acquisition probability' does not drive the positive abnormal returns of rivals. Further, we find the positive (or non-negative) abnormal returns of rivals to be robust when considering heterogeneity in merger and rival characteristics.     

Insider Trading: Does Being a Neighbor of the Securities and Exchange Commission Matter?

Using a perception‐based crime deterrence approach, we present evidence that corporate insiders located closer to the Securities and Exchange Commission regional offices trade less frequently on their own company's stocks, while they earn higher abnormal returns from such insider transactions. These results are robust to several additional tests. Our further analysis indicates that such differences in trading profitability are mitigated during the periods of a high level of legal jeopardy such as the periods around earnings announcements and mergers and acquisitions. These findings are consistent with the view that Securities and Exchange Commission oversight has an impact on insiders' trading behavior by influencing their perceptions of sanctions risk.

Accounting for the trend in trade union recognition in Ireland

Considerable controversy surrounds the issue of union recognition in Irish industrial relations. Academic commentators have sought to identify and explain the trend in recognition since the 1980s. Their arguments are examined and tested. No secular rise in non‐recognition is evident, and ‘individualisation’ and ‘union substitution’ are shown to add little to explaining the trend. No evidence is found that the trend reflects Irish employers pursuing union suppression and US‐employers pursuing union substitution. The significant development is a sharp rise in non‐recognition among new US employers. Their anti‐union animus does not, however, appear to be coupled with any distinctive or generalised union avoidance strategy.     

The joint decision to manage earnings through discretionary accruals and asset sales around insider trading: Taiwan evidence

This study assesses the joint decision of multiple earnings–management tools around insider trading. The Taiwanese evidence indicates significantly higher magnitudes of both discretionary accruals and asset sales before insider selling. In addition, to investigate the endogenous relationship between discretionary accruals and asset sales, this study develops a set of simultaneous equations and includes the inverse Mill’s ratio as a regressor to account for firms that choose not to use asset sales. The results indicate a marginal complementary correlation between discretionary accruals and asset sales before insider selling. Further tests find this complementary correlation becomes stronger when accompanying abnormal insider selling. The findings support the view that insiders consider both tools jointly and adjust them as complements to meet their directional earnings management objective.     

Information Consequences of Accounting Conservatism

Abstract

We study the information consequences of conservatism in accounting. Prior research shows that information asymmetries in capital markets lead to firm-level increases in conservatism. In this paper, we further argue that increases in conservatism improve the firm information environment and lead to subsequent decreases in information asymmetries between firm insiders and outsiders. We predict and test if this decrease in information asymmetries manifests itself through: (a) a decrease in the bid–ask spread and in stock-returns volatility, and (b) an improved information environment for financial analysts, leading to more precise and less dispersed forecasts, and to more analysts following the firm. Using a large US sample for the period 1977–2007 and several proxies for conservatism we find robust evidence consistent with our expectations. Our results are in line with conservatism being useful not only for debt-holders, but also for equity-holders.     

Trade union membership and dismissals

In Germany, there is no trade union membership wage premium and a membership fee of 1% of the gross wage. Therefore, prima facie, there are strong incentives to free-ride on the benefits of trade unionism. We establish empirical evidence for a private gain from trade union membership which has hitherto not been documented: in Western Germany, union members are less likely to lose their jobs than non-members. In particular, using data from the German Socio-Economic Panel we are able to show that roughly 50% of the observed raw differential in individual dismissal rates can be explained by the estimated average partial effect of union membership.     

The effects of tax and regulatory changes on commercial bank dividend policy

The literature concerning the Tax Reform Act of 1986 (TRA) is extensive, but generally does not consider dividend policy changes related to TRA’s passage. One exception is Casey et al., but that work omits banking. An examination of banks is especially apt given TRA’s changes in tax rates and municipal bond categorization. Results show bank dividend policy to be different from other industries, as banks show no relation to past growth rates, beta, or an insider ownership as Rozeff’s model holds. The results support the idea that the lower the taxes, the higher the payout which is contrary to the dividend irrelevancy argument. However, the results are not robust in tests using data from a later period meant to more closely examine changing capitalization requirements’ impact on dividend policy.     

Insider econometrics: A roadmap with stops along the way

For the past twenty five years, economists have been building theories of the optimal management of firms. For example, economic models suggest that under some conditions, piece rate pay raises performance, and under other conditions, promotions tournaments raise performance. Some of these theories have been tested, others have not. Economists are now using new empirical research tools, that we label “insider econometrics,” to test the impact of management practices on productivity: to model how much productivity changes; to model why management practices raise productivity; and to examine which firms benefit and why from alternative management practices. The methodology we describe is “insider” because it uses inside knowledge and data from within firms. It is “econometrics” because the methodology is often the application of treatment effects methods to modeling changing management practices within firms. However, the methods and challenges of insider econometrics are unique, and we identify several key features that are important in undertaking empirical studies of workers' productivity. Now that more firms are keeping data on employees, it is time to improve our analysis of the empirical study of the productivity of workers within firms.     

Do Managers Trade on Public or Private Information? Evidence from Fundamental Valuations

Using accounting-based (residual income) valuations, this study examines the extent to which abnormal returns after insider share trades are explained by private information versus mispricing of public information. For a sample of insider trades in the Netherlands (1999–2008), I find that managers' share purchase decisions are associated with positive future abnormal returns as well as equity undervaluation. Even though undervaluation results in predictable price increases, positive abnormal returns following purchases persist after controlling for fundamental valuations. Thus, this study provides evidence on the sources of managers' personal trading gains and suggests that positive abnormal returns after insider share purchases reflect both private information and managers' responses to market mispricing of public information.     

Union algebra: Unionization,productivity and labor intensity restrictions

Two models are developed to investigate unionism effects. The first assumes Cobb-Douglas technology, derives an explicit cost function allowing for noncost minimization and separates productivity and labor intensity effects. The second assumes a more flexible translog shadow cost function and isolates a neutral productivity effect and factor-specific composite effects. The models are estimated using Allen's construction data. Both models indicate a positive union productivity effect in office construction and a negative union productivity effect in school construction. The Cobb-Douglas model indicates a binding labor-to-materials restriction in both office and school construction, but this evidence disappears with the nonminimum cost function.     

Insider ownership and dividend signals: Additional evidence from the banking industry

This study investigates the relationship between the concentration of insider ownership and the share-price response to dividend-policy changes implemented by bank holding companies (BHCs). Using a cross-industry sample, previous research (Born 1988) found that there are differences in the magnitude of the share-price response to dividend initiations which may be explained by the concentration of insider ownership of the sampled firms. We hypothesize that the concentration of insider ownership does not play a role in differences in share price for BHCs due to the presence of regulatory monitors. The results of this study support our hypothesis.
