The purpose of this paper is to argue that corruption is inherently unmeasurable. Measures of corruption produced by different sources are highly unsatisfactory. Useful measures may be possible for specific purposes in limited contexts. Reasons why highly unsatisfactory measures are in use have to do with politics and power, rather than utility of these measures.

The paper shows that different dimensions of corruption cannot be reduced to a single number without serious loss of information. For example the number and size of bribes cannot be reduced to a single index. The difference between perceptions of corruption and the reality also makes most popular indices useless.

The paper shows that commonly used measures of corruption are useless for their ostensible purposes. Evidence is presented that they are calculated and used for political purposes. In particular, they provide convenient excuses for the widespread failure of the structural adjustment programs of IMF and World Bank.

The paper's findings cast doubt on the vast amount of research which takes the corruption measures as objective and factual, and attempts to find causal factors for corruption, as well as effects of corruption on growth and other variables.

If I do not count the introductory essay by the editors, the book Economics and Language (Henderson, et al., 1993), can be divided into three substantive parts. The first is titled rhetoric and critical theory, the second, controversy and hedging in economics, and the third, language and the history of economic thought. Again not counting the introduction, the volume consists of a total of ten essays: four in the first part and three each in the remaining two. In Part I, the reader is introduced to a realist philosophy of economic rhetoric, to Ricoeur and the significance of the hermeneutic project for economics, to Bakhtin's dialogism in the formation of the canon, and to the relevance of Derrida and of deconstructive methods for rational choice theory. Part II is concerned with the “stylistics” of two sets of material: with the “debate” between Milton Friedman and his critics; and with 11 articles chosen from a recent issue of the Economic Journal. Finally, the three essays in Part III are devoted to Adam Smith, to Edgeworth and to the response of six elementary textbooks to a “puzzle” of economic theory.

The purpose of the study is to explore contributions made in Islamic economics methodology, particularly in the use of mathematical models used to build Islamic economic theories.

The methodology adopted is a survey by means of literature review.

Overuse of mathematical models in economics has it apparent weakness in simplifying complex realities and use of impracticable assumptions. But, that notwithstanding, they have a role to play in the development of Islamic economics. Empirical analysis in Islamic economics has weaknesses, including the very fact that moral phenomenon in Islamic economics is difficult to quantify, but its contribution, just like mathematics, is needed to develop the field. Islamic economics adopt mathematical models that do not cause obstacles in achieving the aim of Islamic economics, which is Falah. Where it is harmful, it is discarded. Islamic economics has yet to have a universally accepted research methodology; instead, numerous methodologies are used today. The poor use of mathematics in Islamic economics by new researchers, among other factors, may be due to young researchers’ poor background in mathematics.

The paper is unique in looking at the topic of Islamic economic methodology from the angle of application of mathematical models.

This paper aims to investigate the subject matter of Islamic economics that will be the object of a study as a discipline by classifying and unifying different approaches proposed by Islamic economists.

The paper is a conceptual paper using discursive analysis analysing the perspective and approaches proposed by Islamic economists in defining economic problems from an Islamic perspective. The perspective and approaches proposed are classified and analysed for their implications in constructing the subject matter of discipline.

Islamic economics, as a new body of knowledge, needs to clarify the economic problems that will be its subject matter. The paper brings an insight into the subject matter of Islamic economics as conceived by scholars in two approaches, namely, economic problems “as they are” and economic problems “as they should be”. The paper also proposes a unified perspective in defining the subject matter of Islamic economics for further development of the discipline.

This paper only provides philosophical guidance for researchers in mapping the problems and the goals of the policy being studied, although it does not offer any practical use for policymaking as each policy is faced with different and specific cases. This paper may be used to assist future researchers in shaping other unexplored fields in Islamic economics as a body of knowledge.

Islamic economics as a discipline will be strengthened if it has a clear subject matter that will be the object of study. However, the conception of economic problems proposed by Islamic economists is based on life-reality, i.e. of what human beings face in their life (practical-type economic problems as they are) and based on life guidance from the Qur’an on how human beings should live as well as life-objectives, i.e. of what goals he should strive for (ideal-type economic problems as they ought to be) brings implication that there are differences in determining the object of study of Islamic economics.

This paper promotes the unification of two conceptions of economic problems proposed by scholars by defining Islamic economics as “a study of resource appropriation to realize human well-being (maslahah)”. This suggests that economic problems as manifested in life reality will be studied within the grand objective of life in Islam (maqasid al-Shariah), and economic problems as perceived in life goals will be studied in the context of life reality. Islamic economic theory will be formulated not only to solve the apparent problem of “what is” but also formulated in a way that refers to goals (ideals) of “what ought to be” that will provide solutions to current economic problems according to certain vision and to take steps to move in that visionary direction.

Transformational leadership, flexibility and visibility improves project responsiveness to highly unpredictable and impactful events referred as the ‘black swans’ in mega projects (Bloch et al., 2012; Raziq et al., 2018; Zailani et al., 2016). However, these concepts have never been empirically tested in a single framework to determine their significant impact on multi-dimensional project success. The purpose of this paper is to investigate the interactional effects of project flexibility and project visibility on the relationship between transformational leadership and “multi-dimensions” of project success including meeting design goals; impact on customers and benefits to project-based organization.

Empirical data derived from cross-sectional survey of 160 project managers from telecom intensive companies in Pakistan were used to test the conceptual framework developed from recent literature. Partial least squares-structural equation modeling (PLS-SEM) provided detailed analysis of the measurement and structural model. The most recent reflective–formative PLS-SEM approach for higher-order constructs has been introduced.

The results indicate that project managers’ transformational leadership (β = 0.348, p < 0.01), project flexibility (β = 0.221, p < 0.01) and project visibility (β = 0.366, p < 0.01) are positively related with the multi-dimensional project success (second-order formative) construct. Interestingly, the relationship between transformational leadership and project success is influenced by significantly negative moderations established through project flexibility (β = −0.100, p < 0.01) and project visibility (β = −0.093, p < 0.05).

This study in the telecom sector examined the interactional effects of risk mitigating strategies (i.e. project flexibility and project visibility) on the relationship between transformational leadership and multi-dimensional project success. This study creates a basis for future investigations extending to various project types and relevant to different industries especially those involving higher-order (formative) assessments of project success.

The study findings assist project leaders to meet their escalating commitments in achieving project success from a multi-dimensional standpoint. Additionally, this study underscores a renewed perspective of transformational leadership and project outcomes. Despite prevailing understanding developed through prior research, transformational leadership may become less favorable for project success in conditions of increased flexibility and visibility in projects.

Earlier studies have overlooked the multi-dimensional nature of project success (second-order formative) construct, despite several attempts to examine the interplay between transformational leadership and project success. Based on the knowledge gap and non-existence of empirical evidence, the authors introduced and empirically tested the moderating role of project flexibility and project visibility in the relationship between transformational leadership and multi-dimensional project success.

The paper aims to produce new key terminologies for the microfoundations of Islamic economics. The paper attempts to investigate the microfoundations of Islamic economics by exploring new perspective in the key concepts and key terminologies that would explain the behavior of individual and society in an Islamic ethical framework.

The paper is a conceptual paper that attempts to explore the microfoundations of Islamic economics from the primary sources of Qur’anic texts. Literature on the topics, from an Islamic and mainstream economics perspective, are reviewed critically in a comparative perspective.

The key concepts of self-interest, utility maximization and rationality are critically evaluated in an Islamic perspective and new key concepts of huquq, maslahah maximization and taqwa are proposed as alternatives. Those new key terminologies will broaden the horizon in understanding of economic realities of man and society and their relationship and well-being.

The paper is based on conceptual explorations of literature in the microfoundations of economics in the mainstream economics and Islamic economics. This is a conceptual paper, so it did not use any empirical analysis.

The findings of this paper will give insights of the microfoundations of Islamic economics as a discipline. Those unique key terminologies derived from the textual source of Islam (nusus) and intellectual tradition (turath) are important in the attempt to develop a solid body of knowledge.

The paper proposes new key concepts and terminologies to be the microfoundations of Islamic economics as a discipline. It is a new approach in understanding behavior of individual and society in Islamic perspective which are different from the other approach, which modifies the conventional terminologies by adding “Islamic” prefix, such as “Islamic” utility or “Islamic” rationality.

This study aims to investigate the relationship between corporate governance characteristics and the financial performance of both Islamic and conventional banks in the context of an emerging market, i.e. Malaysia.

This study includes 300 bank-year observations from Islamic and conventional banks over the period 2010–2021. The dynamic panel model (generalized method of moments [GMM]) was considered the primary estimation model that solves simultaneity, endogeneity and omitted variable problems as most governance variables are endogenous by nature. Hence, static models are considered biased after conducting the DWH test of endogeneity, and considering dynamic panel GMM is valid proven by Sargan and Hensen and first-order (ARI) and second-order (ARII) tests.

Based on the regression results, the authors discovered that board size, female participation in the board and director remuneration have a significant positive impact on bank performance, whereas board meetings have a significant negative impact. Furthermore, the board governance structure of commercial banks is found to be more passive than that of Islamic banks.

The study’s findings added a new dimension to governance research, which could be a valuable source of knowledge for policymakers, investors and regulators looking to improve existing governance mechanisms for better performance of conventional and Islamic banks.

The goal of this study is to add to the existing literature by focusing on the impact of female board participation and other board governance mechanisms in both conventional and Islamic banks on bank performance.

The Federal Government of Pakistan has been interrogated by the tribal communities of the country regarding socio-economic inclusiveness. The Islamic Republic of Pakistan has a large number of ethnic groups, and most of them are economically vulnerable and societally excluded due to partial governmental policy and societal construction. Most of the tribal groups are concentrated in Baluchistan, North-Western Frontier province and the Federally Administered Tribal Areas (FATA). Due to the lopsided developmental policy and existence of the feudal system, the wealth and lands are concentrated in a handful number of rural elites. The tribal communities are not only socio-economically backward but also trapped by terrorism. Due to financial crisis and large-scale unemployment, tribal youths have been involved with various radical forces and criminal activities. The secessionist movement of the Baloch people has a long history of deprivation. This chapter intends to investigate the socio-economic challenges of the tribal people of Pakistan and the reluctant outlook of the federal government. It will also delineate how the tribal youths are being attached to terrorist groups due to unemployment and how this is more dangerous to the security of Pakistan. This chapter is based on the content analysis method. The basic argument of this chapter is that socio-economic inclusiveness is required in a multi-ethnic country to ensure social harmony, national integration and national security.

This study aims to examine whether information asymmetry (IA) mediates the relationship between women directors and the cost of equity (COE). Specifically, this study posits that women directors tend to lower the COE through the channel of IA.

This study uses the US-listed firms’ data from 2002 to 2014, comprising 11,189 firm-year observations. This study measures the COE by aggregating the four unique market-based COE models and apply pooled ordinary least square to estimate our results.

This study documents that women directors are linked to IA, and that IA is linked to the COE. Furthermore, in the mediation test, IA fully mediates the relationship between women directors and the COE. This study's results also validate the critical mass hypothesis, as the IA shows full mediation between the critical mass of women directors and COE. This study also discusses the limitations and major implications of the results along with possible future directions.

This study also supports the positive role of females in improvising the economic performance of the firms and supporting the sustainable development goals-5 (gender equality).

The originality of this study lies in its theoretical as well as empirical contributions. First, this study follows the line of inquiry of the mediation analysis, thereby contributing by examining whether the relationship between women directors and financial value, i.e. COE, is indirect. Second, in addition to ex post measures of the COE, this study used four ex ante unique market-based models to measure the COE. Most of the prior studies just rely on book-based measures or use a single market-based mode. Third, the findings contribute insights into how women directors add value and benefits firms.
