"Exploring Markets" is a paper series discussing niche markets with interesting characteristics. The paper on hand focuses on the market for diamonds. The paper discusses specific characteristics of supply and demand such as the supply chain from mining to retail, the dismantling of the diamond...

The focus of this study is rent in the diamond industry. Based on extensive datasets and a discussion of all relevant costs, we present resource rent statistics from the diamond industry in key producer countries in emerging economies such as Angola, Botswana, Democratic Republic of the Congo,...

This paper provides the first quantitative assessment of living standards in Angola during the colonial period, with a specific focus on the Companhia de Diamantes de Angola (Diamang), the largest and most profitable company in Portuguese colonial history. Employing the "barebones subsistence...

Modern slavery exists in developed and developing countries and in both labor‐intensive and high‐end sectors. While the business literature has paid attention to the role public, private, and social actors play in combating modern slavery business practices, the contribution science can make...

We conduct a comprehensive study on momentum spillovers in the Chinese stock market using various types of economic linkages. We find that the news co-mention momentum spillover is significantly stronger compared to other forms of momentum spillovers. Using spanning tests and Fama-MacBeth...

We conduct a comprehensive study on momentum spillovers in the Chinese stock market using various types of economic linkages. By developing a flexible and innovative algorithm to identify linkages among listed firms using millions of Chinese business news articles, we find that the news...

The differences on value between Smith and Menger may be other from previously alleged if status is included as a need satisfied only by truly scarce goods.Given our innate desire to distinguish ourselves and be admired, Smith tells us that scarcity is what generates value. So, our desire for...

This article analyzes the potential for further development of mutually beneficial cooperation in the context of sanctions between Russia, the world leader in diamond mining, and India, the largest producer of polished diamonds, as well as the UAE (Dubai) and the EU (Belgium) the world's largest...

Diamond is a form of carbon that has been attracting attention for hundreds of years, owing to its physical and chemical properties of hardness, thermal conductivity, chemical inertness, and transparency. Labor and the long-term impact of a diverse workforce, is one of the most important factors...

In this work we evaluate quantum Fisher information (QFI) of the Ising-XXZ diamond structure at finite temperatures, which is applied to demonstrate the quantum criticality and quantum phase transition in this model. The results show that QFI around quantum critical points decreases or increases...

Mineralization of phthalic acid, a highly refractory organic pollutant was studied by an anodic oxidation process with BDD anode in a highly acidic chromium medium. Synthetic solutions were composed of Cr(III)/Cr(VI), sulfate, sulfuric acid, and phthalic acid (initial form potassium hydrogen...

C-Si bonds are formed by boron-doped selective growth at the diamond-SiO 2 interface. Two-dimensional hole gas (2DHG) C-Si diamond metal-oxide-semiconductor field-effect transistors (MOSFETs) using C-Si bonded have low interfacial density of states and high hole mobility can be expected. C-Si...

The effects of 100 keV nickel (Ni) ion implantation on modifying the surface morphology and the electron field emission (EFE) properties of two types (ultra-nano-crystalline diamond) UNCD films (with or without the addition of nitrogen gas during their deposition process) were studied. The Ni...

In this non-technical introduction to diamond trees and forests, we focus on their application to computation in stochastic volatility models written in forward variance form, rough volatility models in particular

The focus of this study is rent in the diamond industry. Based on extensive datasets and a discussion of all relevant costs, we present resource rent statistics from the diamond industry in key producer countries in emerging economies such as Angola, Botswana, Democratic Republic of the Congo,...

The challenges that are faced during a start-up are due to lack of Culture and Awareness in start-up plan people do not have enough strategy to start-up. Some social issues faced due lack of guidance/mentorship. Indian markets are largely unorganized that create difficulties for start-up to...

Online platforms often assign sellers summary symbols based on whether their ratings pass certain thresholds. Consumers may focus on the symbols and be limited attentive to the ratings. This bias leads to discontinuously increased demand at the thresholds. I use a theoretical model to illustrate...

This paper uses the diamond model theory as the basic research perspective to explore how the upstream and downstream industrial chains of cotton in Xinjiang can escape from the constraints of reality and how their resource endowments can be transformed into competitive advantages. This paper...

Blockchain technology has become widely accepted to demonstrate the provenance of physical goods, but there are open questions about its practical implementation and overall effect on ethical sourcing. In the diamond industry, blockchain enables credibility of the certificate of origin and...

Traditional per capita measures of poverty assign the same poverty status to individuals living in the same household and overlook differences in living standards within households. There has been a long-standing need for a tool that enables poverty measurement at the individual level, while...

Purpose: Industry 4.0 offers a new network approach by using advanced Information and Communication Technologies (ICT) and for manufacturing industries in particular. This paper analyzes the understandings of heavy manufacturing industry in Turkey about the concept of Industry 4.0 as well as its...

There was nothing preordained about arbitration becoming shorthand for investor-state dispute settlement. The ICSID system was built on the assumption that disputing parties would choose conciliation to settle their disputes. Those expectations went unrealized as arbitration rose to prominence,...

Alternative index products often achieve improved performance at the cost of increased exposure to risk. In this study, we propose a portfolio tilting strategy that alleviates the risks inherent to alternative indices by projecting fundamental factors on risk factors to purge the influence of...

This study explores Porter's diamond of national competitiveness, by critically examining both the analytical virtues, the extensions, and the criticisms it has received over time. The aim is to analyse the stage in which the study of the diamond is currently in, about twenty years after the...

The energy needs of India have increased many folds in recent years due to industrialization and ever-increasing population. Wind energy offers excellent opportunities in fulfilling the energy needs of the country. Being renewable, it has enormous resource potential. Since the last decade, the...

This paper addresses two practical investment questions: Is investing in the diamond equity market a more feasible and liquid alternative to investing in diamonds? Additionally, is diamond equity affected by polished diamond prices? We assemble an original database of diamond mining stock prices...

The decoy effect (DE), first introduced by Huber et al. (1982), has been robustly documented across dozens of product categories and choice settings using lab experiments. However, in the literature, the DE has never been verified in a real marketplace. In this paper, we empirically test and...

This discussion paper examines the possibilities of relationships between two seemingly disparate industries, blockchain and the extractive sectors, by considering the potential for blockchain solutions in the mining of high-value diamonds, looking in particular at the supply chain, oversight,...

"The history of mass-market diamonds goes back to German imperialism in Southwest Africa. Corporate power and state violence combined in the genocide of the Herero and Nama peoples, whose mineral-rich land supplied budding consumer demand in the United States. Steven Press makes clear that mass...
