Abstract
Relative to the randomized controlled trial (RCT), the basic regression discontinuity (RD) design suffers from lower statistical power and lesser ability to generalize causal estimates away from the treatment eligibility cutoff. This chapter seeks to mitigate these limitations by adding an untreated outcome comparison function that is measured along all or most of the assignment variable. When added to the usual treated and untreated outcomes observed in the basic RD, a comparative RD (CRD) design results. One version of CRD adds a pretest measure of the study outcome (CRD-Pre); another adds posttest outcomes from a nonequivalent comparison group (CRD-CG). We describe how these designs can be used to identify unbiased causal effects away from the cutoff under the assumption that a common, stable functional form describes how untreated outcomes vary with the assignment variable, both in the basic RD and in the added outcomes data (pretests or a comparison group’s posttest). We then create the two CRD designs using data from the National Head Start Impact Study, a large-scale RCT. For both designs, we find that all untreated outcome functions are parallel, which lends support to CRD’s identifying assumptions. Our results also indicate that CRD-Pre and CRD-CG both yield impact estimates at the cutoff that have a similarly small bias as, but are more precise than, the basic RD’s impact estimates. In addition, both CRD designs produce estimates of impacts away from the cutoff that have relatively little bias compared to estimates of the same parameter from the RCT design. This common finding appears to be driven by two different mechanisms. In this instance of CRD-CG, potential untreated outcomes were likely independent of the assignment variable from the start. This was not the case with CRD-Pre. However, fitting a model using the observed pretests and untreated posttests to account for the initial dependence generated an accurate prediction of the missing counterfactual. The result was an unbiased causal estimate away from the cutoff, conditional on this successful prediction of the untreated outcomes of the treated.

Abstract
Purpose
The purpose of this paper is to contribute to the existing disclosure literature by examining the determinants of corporate risk disclosure (CRD) in the internet reporting for a sample of Egyptian listed companies on the Egyptian Stock Exchange (EGX).
Design/methodology/approach
This study depends on a sample of 76 Egyptian companies included in the EGX 100 in the period 2012-2014. The study applies a content analysis and uses a sentence-based method to measure CRD in the internet reporting. Ordinary least-squares regression analysis is used to examine the impact of firm and board characteristics on CRD in the internet reporting.
Findings
The empirical analysis shows that large Egyptian companies tend to disclose more risk information in their internet reporting. Moreover, the results indicate that there is a significant positive association between sector type and CRD in the internet reporting. The results show non-significant association between CRD and other firm characteristics (cross listing and level of risk). Finally, there are no significant associations between CRD and board characteristics variables (board size, board composition and CEO duality).
Research limitations/implications
The study’s findings have practical implications. It aids in informing policy makers considering implementing new economic reform programs about the properties of Egyptian companies that disclose risk information in their internet reporting. It provides insights on CRD in Egyptian companies for standards setters and professional authorities to improve risk reporting practices to help stakeholders in making good decisions.
Originality/value
This study is one of the first studies to examine the determinants of CRD in the internet reporting for a sample of Egyptian companies.

Abstract
Purpose
The purpose of this paper is to present the development of cumulative rainfall deficit (CRD) indices for corn in Shandong Province, China, based on high-resolution weather (county, 1980-2011) and yield data (township, 1989-2010) for five counties in Tai’an prefecture.
Design/methodology/approach
A survey with farming households is undertaken to obtain local corn prices and production costs to compute the sum insured. CRD indices are developed for five corn-growth phases. Rainfall is spatially interpolated to derive indices for areas that are outside a 25 km radius from weather stations. To lower basis risk, triggers and exits of the payout functions are statistically determined rather than relying on water requirement levels.
Findings
The results show that rainfall deficits in the main corn-growth phases explain yield reductions to a satisfying degree, except for the emergence phase. Correlation coefficients between payouts of the CRD indices and yield reductions reach 0.86-0.96 and underline the performance of the indices with low basis risk. The exception is SA-Xintai (correlation 0.71) where a total rainfall deficit index performs better (0.87). Risk premium rates range from 5.6 percent (Daiyue) to 12.2 percent (SA-Xintai) and adequately reflect the drought risk.
Originality/value
This paper suggests that rainfall deficit indices can be used in the future to complement existing indemnity-based insurance products that do not cover drought for corn in Shandong or for CRD indices to operate as a new insurance product.

Abstract
The NHS Centre for Reviews and Dissemination (CRD) was established to help provide clear summaries of research‐based knowledge on the effectiveness and cost‐effectiveness of health care interventions. This paper summarises the ways in which CRD helps produce and disseminate this research intelligence to the NHS and its customers. Systematic reviews on topics prioritised by the NHS are conducted or commissioned. Some are disseminated as Effective Health Care bulletins to a wide range of people in the NHS. Two databases are available on line which provide structured critical abstracts of reviews of research and economic evaluations have been developed. Some of the most important reviews are also disseminated as Effectiveness Matters. CRD also provides research input into a number of projects such as cancer guidance for purchasers, and consumer and professional informed choice leaflets in maternity care, cataracts and glue ear.

Abstract
Purpose
Introducing radical changes to the methodologies for the determination of capital requirements, the final stage of the Basel III standards, which is referred to as “Basel IV” by the industry, will be a significant challenge for the global banking sector. This article reviews the main components of the new framework, analyses its ongoing implementation in the European Union and discusses its potential impact on banks, putting forward policy recommendations.
Design/methodology/approach
This article uses primary sources such as the publications by the Basel Committee for Banking Supervision and the European Commission. It also reviews the secondary sources, including both academic articles and analyses by various stakeholders. However, this article does not undertake any empirical analysis.
Findings
This article discusses that Basel IV will introduce strategic, operational and regulatory challenges for banks in scope. It also identifies a number of areas which are subject to further debate in the European Union such as the enhanced due diligence requirements under the new credit risk framework; governance, reporting and control rules under the operational risk framework; exemptions for certain derivative transactions under the credit valuation adjustment framework and the level of application of the capital floors within banking groups. This article concludes that the global implementation of the reforms by all jurisdictions and transposition into national banking laws concurrently with the European Union in line with the Basel Committee's implementation timeline is important from a financial stability standpoint.
Originality/value
The article presents an up-to-date and comprehensive review of the practical implications of Basel IV standards. It analyses the implementation of the standards in the case of the European Union, reviews the potential policy implications and presents recommendations for risk management practitioners.

Abstract
Purpose
The purpose of this paper is to investigate a new and practical decision support model of the coordinated replenishment and delivery (CRD) problem with multi-warehouse (M-CRD) to improve the performance of a supply chain. Two algorithms, tabu search-RAND (TS-RAND) and adaptive hybrid different evolution (AHDE) algorithm, are developed and compared as to the performance of each in solving the M-CRD problem.
Design/methodology/approach
The proposed M-CRD is more complex and practical than classical CRDs, which are non-deterministic polynomial-time hard problems. According to the structure of the M-CRD, a hybrid algorithm, TS-RAND, and AHDE are designed to solve the M-CRD.
Findings
Results of M-CRDs with different scales show that TS-RAND and AHDE are good candidates for handling small-scale M-CRD. TS-RAND can also find satisfactory solutions for large-scale M-CRDs. The total cost (TC) of M-CRD is apparently lower than that of a CRD with a single warehouse. Moreover, the TC is lower for the M-CRD with a larger number of optional warehouses.
Practical implications
The proposed M-CRD is helpful for managers to select the suitable warehouse and to decide the delivery scheduling with a coordinated replenishment policy under complex operations management situations. TS-RAND can be easily used by practitioners because of its robustness, easy implementation, and quick convergence.
Originality/value
Compared with the traditional CRDs with one warehouse, a better policy with lower TC can be obtained by the new M-CRD. Moreover, the proposed TS-RAND is a good candidate for solving the M-CRD.

Abstract
Purpose
The purpose of this paper is to examine corporate risk disclosure (CRD) practices and determinants in the annual reports of Egyptian listed companies during the 2011 political crisis (uprising) in Egypt.
Design/methodology/approach
Content analysis of the annual reports of a sample of non-financial listed companies representing different industry sectors was conducted to investigate attributes and factors underlying their risk disclosures.
Findings
The findings demonstrate that companies disclosed more monetary, future and good risk information. The results show a positive and significant relationship between company size and the level of CRD, a positive but insignificant relationship between the extent of CRD and some company-specific characteristics: industry type, profitability and cross-listing, and a negative and insignificant relationship between corporate reserves and the level of CRD.
Research limitations/implications
A larger sample size would be needed for greater generalization of the findings. This study extends the literature on CRD by examining CRD practices at a time of current and ongoing crisis. However, more research is needed to examine variations in CRD practices before and after the 2011 political crisis.
Practical implications
The results could be used by information users, companies and the capital market authority to inform policy-making and tighten regulations to improve CRD. Recommendations are made for improving the quality and informativeness of risk information.
Originality/value
It is important to investigate CRD practices, considering the dearth of research, particularly in emerging capital markets and during crises, when companies are exposed to more, especially uncontrollable, risks. This study fills a void in literature by examining CRD practices during the 2011 political crisis in Egypt.

Abstract
Purpose
The purpose of this paper is to review the development of the Capital Requirements Directive (CRD) and examine the manner in which this has been implemented for investment firms in Malta. The paper also assesses the challenges that small and medium‐sized investment firms may face as a consequence of the proposed CRD IV, which seeks to safeguard the stability of the European banking sector.
Design/methodology/approach
A literature review of relevant EU and Malta legislation and policy documents has been carried out. The arguments made in the paper are the result of the author's reflections on the subject and discussions held with other policy experts on capital adequacy in Malta and the UK.
Findings
The paper considers the CRD from the perspective of small and medium‐sized investment firms and sheds light on the challenges faced by Malta with regards to the implementation of the CRD for these type of firms. It also examines the approach taken by the Malta Financial Services Authority in order to address these challenges.
Originality/value
Possible future challenges that might arise in view of CRD IV are also considered. It is a central argument of this paper that capturing investment firms, particularly small and medium‐sized firms, within the scope of regulation, the main purpose of which is to address systemic risk, may result in over‐regulation.

Abstract
Purpose
The purpose of this paper is to contribute to the existing disclosure literature by examining the determinants of narrative risk information in the interim reports for a sample of UK non‐financial companies.
Design/methodology/approach
This study uses the manual content analysis to measure the level of risk information in interim report narrative sections prepared by 72 UK companies. It also uses the ordinary least squares regression analysis to examine the impact of firm‐specific characteristics and corporate governance mechanisms on narrative risk disclosures.
Findings
The empirical analysis shows that large firms are more likely to disclose more risk information in the narrative sections of interim reports. In addition, the analysis shows that industry activity type is positively associated with levels of narrative risk disclosure in interim reports. Finally, the analysis shows statistically insignificant impact of other firm‐specific characteristics (liquidity, gearing, profitability, and cross‐listing) and corporate governance mechanisms on narrative risk disclosure.
Practical implications
The study's findings have practical implications. It informs investors about the characteristics of UK companies that disclose risk information in their interim reports. For example, the findings show that narrative risk disclosures are affected by firm size and industry type rather than firms' risk levels (e.g. financing risk measured by the gearing ratio or liquidity risk measured by lower liquidity ratios). Practical implications for managers from these findings are that, in order to keep investors satisfied, companies with high levels of financing and liquidity risks should look at investors' demands for risk disclosure. This will help investors when making their investment decisions.
Originality/value
The determinants of narrative risk disclosure in interim reports have not been explored so clearly in prior research and, therefore, this paper is the first of its kind to examine this research issue for a sample of UK companies.

Abstract
Purpose
The paper aims at identifying the role of online advertising on the purchase intention (PI) of smartphones of Bangladeshi customers. The independent variable (online advertising) has been divided into five dimensional segregations: informativeness (INFO), irritation (IRR), entertainment (ENT), incentives (INC) and credibility (CRD). For increasing the value of investigation to further extent, the authors included two mediators termed as flow experience (FE) and advertising value (ADD).
Design/methodology/approach
The study has been conducted on primary data collected through a structured questionnaire received from a valid sample of 281 smartphone users selected on a random basis. SPSS (Version 24) has been used for descriptive statistical analysis, while structural equation modeling technique (utilizing AMOS 24) has been used to test the hypothetical relationships among the variables.
Findings
After a careful and bias-free statistical analysis, the results indicate that purchase intention is positively and significantly affected by all the independent components INFO, IRR, ENT, INC and CRD. Regarding the mediating effect, FE can partially mediate the relationships between IRR and PI and ENT and PI as both the direct and indirect effects are significant. On the other hand, ADD can partially mediate the relationships between IRR and PI and INC and PI, respectively, since both the direct and indirect effects are significant.
Research limitations/implications
This empirical study is expected to be beneficial for the academicians in finding some unique dimensional aspects regarding online advertising and purchase intentions.
Practical implications
The policymakers can formulate some unique online advertising policies with a view to identifying customer psychology and increase sales volume based on the findings.
Originality/value
Smartphone market in Bangladesh is growing steadily. This empirical paper has shed some lights on the unique role of online advertising on PI of smartphones of Bangladeshi customer base. Since the market scenario in Bangladesh is somewhat unique than those of Western and Eastern countries, the authors hope that the findings will add numerical theoretical and practical values for further investigation in South Asian markets.
