This study aims to examine the deterrent effect of the Market Abuse Directive (MAD) introduced in the European Union in 2003. The purpose is to evaluate whether the Directive has resulted in significant changes in pre-bid stock price run-ups observed in mergers and acquisitions within the Portuguese, Spanish and Greek stock markets.

The study analyzes a sample of 199 mergers and acquisitions in the aforementioned stock markets. The magnitude of pre-bid stock price run-ups is investigated as an indicator of illegal insider trading. The effects of the MAD, toehold positions of bidders and industry similarity between firms involved in the deals are assessed using statistical analysis.

The study’s findings indicate that the MAD has been ineffective in deterring investors from trading on non-public information. Pre-announcement price run-ups remain significant, suggesting ongoing illegal insider trading practices. Additionally, the research reveals that pre-bid stock price run-ups tend to be lower when bidders have established a larger toehold position in the target and when the firms involved in the deal belong to the same industry.

This study contributes to the existing literature by providing empirical evidence on the ineffectiveness of the MAD in deterring illegal insider trading. The findings highlight the limitations of increasing penalties without an effective monitoring system in place. Furthermore, the study identifies additional factors, such as toehold positions and industry similarity, that influence the magnitude of pre-announcement price run-ups in mergers and acquisitions.

This paper aims to examine the relation between SEC regulations centered on board of director independence and financial reporting quality and investigates the different routes to board independence.

The sample includes 1,248 firm observations whose board composition is compared between 2001 and 2008. Each firm is categorized based on how they increase board independence. The authors test the hypotheses using ordinary least squares regression models.

Results show that firms choose between multiple routes when complying with the independence requirements, and how firms operationalize the SEC requirement impacts financial reporting quality. Specifically, firms that achieve increased board independence through increased board size are associated with higher financial reporting quality. However, there is no association between higher financial reporting quality and a subsequent increase in audit fees. Suggesting the reporting quality results from the board monitoring function and not from an increase in auditor effort.

No evidence exists on how a firm’s chosen route to increased board independence relates to financial reporting quality.

Despite its potential as an emerging market for Islamic financial services, Uzbekistan has lagged in legislative support. This study aims to evaluate the feasibility of introducing an Islamic capital market (ICM) in Uzbekistan, preceding a broader industry establishment.

The authors begin by assessing Islamic finance literacy and the potential demand for ICMs in Uzbekistan. The authors then scrutinize Uzbekistan’s capital market legislation and its readiness. This analysis uses primary data, including surveys and interviews, and secondary data from literature and financial legislation.

This study highlights a significant demand for ICMs, despite low Islamic finance awareness in Uzbekistan. Presently, Uzbekistan’s capital market development is lacking, with regulations not yet suitable for ICMs. As a result, legal and operational enhancements are needed.

The authors provide essential policy recommendations for authorities and practitioners to facilitate the effective launch of ICMs and enhance Uzbekistan’s capital market stature.

To the best of the authors’ knowledge, this is the first study offering an in-depth analysis of the potential and feasibility of ICMs in Uzbekistan.

Existing studies suggest that negative impacts emanating from corporate fraud revelations may diffuse to other firms through lower trust and lower market participation. Extending this literature stream, the authors examine whether corporate fraud revelations are associated with higher costs of raising capital through initial public offerings (IPOs) for industry peers.

The authors employ several analysis techniques including univariate analysis, multivariate regressions, propensity score matching methodology, and probit estimation. The sample consists of 3,015 US IPO firms for the 1996–2021 period.

By adopting US private securities class action lawsuits as a proxy for the presence of corporate fraud, the authors find that fraud revelations are associated with higher IPO underpricing, higher post-IPO stock return volatility and increased likelihood of withdrawal from the offering for industry peers. The findings are robust to alternative industry definitions and litigation proxies and to the inclusion of a battery of controls, including industry, state and year fixed effects.

This study presents private firms with an additional industry litigation factor to consider when assessing the marginal costs of going public.

Although several microeconomic and macroeconomic factors driving banks' credit quality have been well-studied in the literature, one aspect which appears to have received limited attention is bankruptcy reforms. To address this issue, the author exploits data on Middle East and North Africa (MENA) country banks during the period 2010–2020 and examines the impact of bankruptcy laws on their credit quality.

In view of the staggered nature of the implementation of legal reforms across countries, the author utilize a difference-in-differences specification to tease out the causal impact.

The findings reveal that bankruptcy reforms lead to a significant improvement in banks' credit quality. The impact is manifest mainly for conventional banks and driven by an increase in recovery intensity. The author also presents evidence which shows that such reforms exert positive real effects, although this impact differs across country characteristics.

The study is among the early ones for the MENA region to assess the interlinkage between bankruptcy reforms and banks' credit quality.

The inadequacy of regulations, the uncertainty of the quality of houses produced and the needs of users all highlight the need for a house analysis in Turkey. The goal of this study is to understand housing quality in Turkey based on the gap between expectations and existing housing stock, to identify the main housing expectations and the problematic issues in the current housing situation.

The authors designed a survey using the quality indicators of several well-known housing quality assessment tools to reveal residents' housing preferences and current housing situation in Turkey. The authors analyzed the survey results to identify the gap between housing preferences and existing conditions to reveal the housing quality of Turkish housing.

Overall results show that residents in Turkey, regardless of their demographics, want and need better houses. It was determined that physical conditions, safety, aesthetics and accessibility are the issues for which the expectations of the participants are high and the lack of which is most felt.

This paper reveals the residents' perspective on housing and their housing quality. It emphasizes the need for more research on housing quality, the need for updated regulation and necessity of a housing quality assessment tool in Turkey.

This paper aims to propose a train timetable rescheduling (TTR) approach from the perspective of multi-train tracking optimization based on the mutual spatiotemporal information in the high-speed railway signaling system.

Firstly, a single-train trajectory optimization (STTO) model is constructed based on train dynamics and operating conditions. The train kinematics parameters, including acceleration, speed and time at each position, are calculated to predict the arrival times in the train timetable. A STTO algorithm is developed to optimize a single-train time-efficient driving strategy. Then, a TTR approach based on multi-train tracking optimization (TTR-MTTO) is proposed with mutual information. The constraints of temporary speed restriction (TSR) and end of authority are decoupled to calculate the tracking trajectory of the backward tracking train. The multi-train trajectories at each position are optimized to generate a time-efficient train timetable.

The numerical experiment is performed on the Beijing-Tianjin high-speed railway line and CR400AF. The STTO algorithm predicts the train’s planned arrival time to calculate the total train delay (TTD). As for the TSR scenario, the proposed TTR-MTTO can reduce TTD by 60.60% compared with the traditional TTR approach with dispatchers’ experience. Moreover, TTR-MTTO can optimize a time-efficient train timetable to help dispatchers reschedule trains more reasonably.

With the cooperative relationship and mutual information between train rescheduling and control, the proposed TTR-MTTO approach can automatically generate a time-efficient train timetable to reduce the total train delay and the work intensity of dispatchers.
