Inference for the two-parameter bathtub-shaped distribution based on record data

Here we consider the record data from the two-parameter of bathtub-shaped distribution. First, we develop simplified forms for the single moments, variances and covariance of records. These distributional properties are quite useful in obtaining the best linear unbiased estimators of the location and scale parameters which can be included in the model. The estimation of the unknown shape parameters and prediction of the future unobserved records based on some observed ones are discussed. Frequentist and Bayesian analyses are adopted for conducting the estimation and prediction problems. The likelihood method, moment based method, bootstrap methods as well as the Bayesian sampling techniques are applied for the inference problems. The point predictors and credible intervals of future record values based on an informative set of records can be developed. Monte Carlo simulations are performed to compare the so developed methods and one real data set is analyzed for illustrative purposes.

Examining the extent of and determinants for sustainability assurance quality: The role of audit committees

This study examines the extent of and determinants for sustainability assurance quality. Data comprise sustainability assurance statements published by the top 100 listed companies in Australia and New Zealand from 2017 to 2019. The findings indicate that Australian companies lead their New Zealand counterparts in sustainability assurance. Although sustainability reporting has risen, assurance rates remain significantly low. Accountants dominate the market, and companies prefer to use their own auditors for sustainability assurance work. Sustainability assurance quality is poor and does not vary significantly among Australian and New Zealand companies. Low-quality sustainability assurance plays a limited role in mitigating potential stakeholder–agency conflicts. The regression analysis indicates that audit committee characteristics such as members' independence, industry/market expertise, and attending meetings enhance sustainability assurance quality, whereas audit committee size has no affect. These findings suggest that audit committee characteristics such as independence, industry expertise, and regular meeting attendance have the potential to reduce stakeholder–agency conflicts by improving the quality of sustainability statement assurance. Our findings build on the sustainability assurance literature by exploring current trends in sustainability assurance practices in Australia and New Zealand where corporate governance codes have been recently revised. Further, these findings are timely given recent changes in standards (International Standard on Assurance Engagements [ISAE] 3000 and Global Reporting Initiative [GRI]). Our study contributes to the audit committee literature and sheds light on the role played by audit committee characteristics on sustainability assurance statement quality. The study findings potentially offer useful insights for practitioners, standard setters, and regulators.     

Valuing Homeownership

Housing tenure decision combines financial, economic and socio-psychological factors. This paper considers the global premium associated to homeownership. On the one hand, homeownership is associated to private benefits of being an owner. On the other hand, overinvestment in housing is harmful to diversification and distorts portfolio management. This trade-off, similar to the one associated to corporate private benefits of control, is the cornerstone of our theoretical model based on the expected utility maximization. The originality of the model comes from its simplicity. Furthermore, the empirical implementation of the model, using price and rent data normalized by square-meter, exhibits a homeownership premium for houses in the Brussels Region reaching at least 9% of the housing price. The findings are robust to several methodological refinements. In particular, they confirm the link between liquidity constraints and house prices documented in the literature. However, the premium may largely vary from one place to another, according to tax laws, cultural habits and social status associated to tenure.     

Development banking and technological development: a case study of industrial development banks in the GCC countries

This article explores the important role of Industrial Development Banks in promoting the quality of technological development. It is argued that the historical experiences of the developed economies and several developing economies during recent times support the need and potentials of a more pro-active role by Industrial Development Banks. Against this background, the specific experiences of Industrial Development Banks in the Gulf Co-operation Council Countries are examined and the results of a select field survey are reported. This exploratory study suggests that some fundamental steps are needed in order to develop Industrial Development Banks from being comparatively passive conduits of technological aid to more active promoters of technological development.     

Affects of alliance entrepreneurship on common vision,alliance capability and alliance performance

The underlying theoretical argument of our study concerns that value from alliance knowledge may be created not only through exploitation and augmentation of the existing organizational knowledge base, but more through entrepreneurial actions in accessing and integrating key strategic resources that exist in the alliance relationship. In this view, our study investigates the role of alliance entrepreneurship with its effects on common vision, alliance capability and alliance performance in penetrating into the foreign markets. This study develops and empirically tests a model that specifically focuses on (1) to what extent alliance entrepreneurship relates to developing a common vision between alliance and organizational knowledge, (2) to what extent alliance entrepreneurship relates to the alliance capability and alliance performance respectively, and (3) to what extent barriers to alliance knowledge acquisition and learning orientation moderate the relationship between alliance entrepreneurship and alliance capability.Based on a sample of 100 ICT firms, findings of our study reveal a positive and significant affect of alliance entrepreneurship on common vision, alliance capability and alliance performance. However, more significant support is received for the relation between alliance entrepreneurship and alliance capability through moderating interaction effects of barriers to alliance knowledge acquisition and firm level learning orientation.     

Clusters,Chains and Compliance: Corporate Social Responsibility and Governance in Football Manufacturing in South Asia

A recent concern in the debate on corporate social responsibility (CSR) in developing countries relates to the tension between demands for CSR compliance found in many global value chains (GVCs) and the search for locally appropriate responses to these pressures. In this context, an emerging and relatively understudied area of interest relates to small firm industrial clusters. Local clusters offer the potential for local joint action, and thus a basis for improving local compliance on CSR through collective monitoring and local governance. This article explores the interrelationship between global governance, exercised through GVC ties, and local governance, via cluster institutions, in ensuring compliance with CSR pressures. It undertakes a comparative analysis of two leading export-oriented football manufacturing clusters in South Asia that have both faced common challenges on child labour. The article shows that both forms vertical and horizontal governance have played a part in shaping the response of the two clusters on child labour. Moreover, these two distinct forms of governance have also led to quite differentiated outcomes in terms of forms of work organization and child labour monitoring. This raises broader questions on how global CSR demands can locally be better embedded and the conditions under which football stitchers labour in these new work forms.     

Trend forecasting for stability in supply chains

This paper revisits the use of trend forecasting to determine ordering policy in supply chains by viewing it as a part of the control process for making the supply responsive to demand. Trend forecasting is often used to assess demand — a tracked variable in the control context, which drives supply — a tracking variable. Used in this way, it is often observed to increase instability creating the so-called bullwhip effect. Trend is used on the other hand with reliability to increase stability in controller control, but with the difference that a trend of a tracking variable is used to drive correction. While both processes involve use of trend to determine policies for achieving reliable performance, the outcomes of the former are variable while those of the later can create improvement in control with certainty. The similarities and differences between the two processes are discussed and guidelines developed for applying trend forecasting to enhance stability in supply chains.     

Does the Quality of Institutions Limit the MENA's Integration in the World Economy?

Using a large sample of countries over the 1990s, this paper examines the extent to which institutions’ functioning disables a greater participation of the Middle East and North Africa (MENA) in the world economy. It focuses on the impact on manufactured exports and FDI attractiveness and considers a broad index of political risk as well as indices targeted toward specific aspects of governance (corruption, government effectiveness and the rule of law). The results are robust to different econometric approaches and lend strong support to the hypothesis that the functioning of institutions may disable the participation of MENA countries in the world economy. They suggest that the impact of an improvement in the quality of institutions may result in a sensitive increase of FDI inflows and manufactured exports. That increase is comparable to the one resulting from liberalisation policies. Hence, although institutional reforms can take time, they deserve the necessary efforts given their outcomes as compared to other reforms.
