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.

The purpose of this paper is to discuss implications of the global crisis for economic and financial research and policy.

The paper reviews many recent studies on the crisis and offers the author's views on some of the most important lessons to be drawn from the crisis

The review counters views that the crisis reflected a basic failure of economics, but agrees that it undercuts some particular theories and approaches to economics. More attention needs to be given to imperfections in the operation of both markets and governments, drawing on insights from behavioral and neuro economics and finance and political economy analysis and recognizing the importance of limited information and uncertainty about correct models. The creation of perverse incentive structures explain a large part of the financial excesses that led to the crisis. Financial considerations need to be integrated much more closely with macroeconomic analysis and financial risk analysis needs to pay more attention to economic considerations. Useful insights can be drawn from many different theories and approaches and we should not expect any one theory to have all the answers. The excesses observed in the advanced economies do not imply that there are not enormous benefits to be gained from further financial liberalization in emerging market economies, but they do show that great care must be taken in establishing strong supervision of such liberalizations and highlight many of the dangers to look out for.

The paper offers a guide to the literature for those interested in learning more about the causes and effects of the crisis and policy responses and offers a number of suggestions for fruitful research topics and policy strategies.

Discusses the heritage of John Maynard Keynes in terms of application and results of his new economic philosophy over the last four decades. Compares the Keynesian school of thought with other classical and contemporary economists in relation to foundations of monetary and economic analysis, the economics of stable equilibrium, and the economics of disequilibrium. Comments on Keynes’ concept of economic stability, his view on the instability of money and monetary reform, his concept of monetary policy and of the pure theory of money, and his misjudgement of the mixed nature of the modern gold standard. Examines the provisions of the US Federal Reserve Act (1913), focusing on the Federal reserve systems’ nature and functioning, cited by Keynes as a prototype of a modern gold standard. Concludes with an examination of the international aspect of the modern gold standard.

The purpose of this paper is to describe the main ways in which large amounts of information have been integrated to provide new measures of food consumption and agricultural production, and new methods for gathering and analyzing internet-based data.

This study reviews some of the recent developments and applications of big data, which is becoming increasingly popular in agricultural economics research. In particular, this study focuses on applications of new types of data such as text and graphics in consumers' online reviews emerging from e-commerce transactions and Normalized Difference Vegetation Index (NDVI) data as well as other producer data that are gaining popularity in precision agriculture. This study then reviews data gathering techniques such as web scraping and data analytics tools such as textual analysis and machine learning.

This study provides a comprehensive review of applications of big data in agricultural economics and discusses some potential future uses of big data.

This study documents some new types of data that are being utilized in agricultural economics, sources and methods to gather and store such data, existing applications of these new types of data and techniques to analyze these new data.

John Kwoka’s Mergers, Merger Control, and Remedies is a meta-analysis of “retrospective” academic studies of consummated mergers and other horizontal arrangements. Based on this meta-analysis, Kwoka strongly criticizes federal enforcement policies, claiming that the agencies permit far too many anticompetitive mergers to go unchallenged, and are far too willing to accept remedies that fail to prevent a significant loss of competition. Kwoka claims further that this excessive leniency is the culmination of a trend reflecting deliberate policy choices made over the last several decades.

In a forthcoming critique, Vita and Osinski challenge Kwoka’s analysis and his conclusions, identifying serious flaws in the size, construction, and composition of his sample, and in the statistical analysis of the data drawn from that sample. In a published response to Vita and Osinski, Professor Kwoka offers a number of objections and counter-arguments. In this rejoinder, I respond to Professor Kwoka.

The rediscovery and analytical reconstitution are present tendencies in much of social science, especially economics and sociology. The emergence and expansion of the so‐called new institutional economics exemplify these tendencies as do attempts at revival and rehabilitation of the old institutional economics. Analogous tendencies have been manifested in sociology by the further development of economic sociology, especially by various reformulations of its classical premise of institutional structuration and embeddedness of economic behavior. Nevertheless, much of mainstream economics tends to neglect or play down certain salient divergences between the latter's neoclassical or orthodox institutionalism, and heterodox or critical institutionalism advanced by the old institutional economics as well as by economic sociology. Identifies and elaborates such divergences between these seemingly homologous varieties of institutionalism. Since institutionalist varieties and tendencies in both economics and sociology are considered, represents a contribution to an interdisciplinary treatment of social institutions, a treatment originally proposed by the old institutional economics of Veblen et al., the German historical school as well as by Weberian‐Durkheimian classical economic sociology.

The first set of introductory notes to the graduate study of the history of economic thought, and the reasons for their use, was published in Volume 22-B (2004). Subsequently, while distributing the first set in my graduate courses, I initiated a largely new, second set of introductory topics, using a new outline for presentation in each course of lectures on further introductory ontological, epistemological and hermeneutic topics that went beyond the materials in the first set. For several years, I lectured using in part an outline of my 1991 essay (cited below). That outline is reproduced here as Set II.1. The notes published below as Sets II.2 and II.3 are composites, as to content and sequence of topics, of subsequent successions of lectures. Whereas the set of notes published in Volume 22-B was distributed to students with only casual accompanying remarks, these served for me as the basis of lectures and were not distributed. No set of notes published here indicates the comments I made, from course to course, when distributing the first set of notes on the first day of class. One difference between II.1 and II.2–3 is the increasing attention to historiographic topics vis-à-vis discourse-analysis topics with the passage of time. The common elements are, first, the social construction of reality, in two senses: the literal creation of society and the interpretations given that creation; second, the distinctions between truth and belief system, and between truth and validity; third, the continuing relevance therefore of epistemology and ontology alongside the rhetoric of economics; fourth, the relations of epistemology and language to policy; and fifth, the importance of limits. During this period of time conflict had erupted between advocates of the rhetorical and epistemological approaches to the history of economic thought. I was teaching that both approaches to the meaningfulness of ideas were important.

Shows the importance of heeding Clem Tisdell’s call to devote attention to values and to consider further the limitations of unbounded rationality models in economic research. Outlines the implications of a criticism of choice theory for environmental decision‐making. The critics of positivist philosophy of science show that it is impossible to carry out any analysis without making value judgements. The economist cannot escape this neither in theoretical analyses nor in applied studies. In relation to Clem Tisdell’s call to consider values without pontificating on them, it is important to make two points. First, the analysts should state as clearly as possible the values that guide their specific analyses. Second, they could provide the decision makers with a range of options that depend on different stakeholders’ ethical positions. Describes elements of the participatory decision‐making process. It is noted that this approach to evaluation may enhance the rationality of the choices; better represent the values of the various stakeholders; and allow an improved interaction between individuals and institutions.

The Austrian School of Economics, pioneered in the late nineteenth century by Menger and developed in the twentieth century by Mises and Hayek, is poised to make significant contributions to the methodology, analytics, and social philosophy of economics and political economy in the twenty-first century. But it can only do so if its practitioners accept responsibility to pursue the approach to its logical conclusions with confidence and absence of fear, and with an attitude of open inquiry, acceptance of their own fallibility, and a desire to track truth and offer social understanding. The reason the Austrian school is so well positioned to do this is because (1) it embraces its role as a human science, (2) it does not shy away from public engagement, (3) it takes a humble stance, (4) it seeks to be practical, and (5) there remains so much evolutionary potential to the ideas at the methodological, analytical, and social philosophical level that would challenge the conventional wisdom in economics, political science, sociology, history, law, business, and philosophy. The author explores these five tenants of Austrian economics as a response to the comments on his lead chapter “What Is Still Wrong with the Austrian School of Economics?”

The purpose of this paper is to synthesize the review of the existing literature attached to the grey economic system theory and applications and aims to offer a comprehensive picture of the contribution brought by the researchers to this particular field. Also, the paper underlines the main research areas within the grey economic theory and applications and serves as an informative summary kit for future research works and research directions.

For appreciating the scientific progress made since the grey systems theory has been initiated to the present, with an accent on the literature dedicated to the economic field, a bibliometrics analysis has been conducted. The Perish or Publish software was used for extracting the needed data from Google Scholar for the entire period since the appearance of grey systems to now-a-days. In addition, an ISI Web of Science (WoS) search has been performed for extracting the grey economic papers. As the main focus is on the economic subject area of the grey systems, only the papers related to this field have been selected.

The total number of grey economic paper from both Google Scholar and ISI WoS database, the number of authors, some citation metrics, H-index, authors’ provenience country, papers’ language, etc., have been presented and analysed. Also, a list with the most cited papers in the grey economic relational analysis, grey economic prediction models and grey economic incidence is putted forward.

Through the bibliometric analysis on grey economic papers written over time, a qualitative analysis was performed on this field in order to underline the main research direction, to analyse what has been done in this field and to determine which can be the next research directions that can emerge from here.

The paper succeeds in enlarging the view regarding the usage of grey systems theory in the economic field, offering a suitable analysis on the considered areas. Even though bibliometrics analysis have been conducted on the grey systems theory field, a grey economic bibliometric analysis has not been done yet, to the authors’ knowledge. Therefore, a synthesized of the existing literature attached to the grey economic system theory and applications is presented in order to offer a more comprehensive picture of the contribution brought by the researchers to this particular field.
