Much of neoclassical economics is concerned with prices—more specifically, with relative prices. Similarly, economists have studied behavior in the face of risk and uncertainty for at least a century, and risk and uncertainty are without a doubt a feature of economic life. It is thus puzzling that price risk—that is, unexpected departures from a mean price level, or price volatility—has received so little attention. In this review, we discuss the microeconomics of price risk. We begin by reviewing the theoretical literature, a great deal of which is concerned with the effects of unstable agricultural prices on the welfare of producers, consumers, and agricultural households. We then discuss the empirical literature on the effects of price risk on economic agents. We emphasize policy responses to agricultural price risk throughout, discussing price stabilization policies from both theoretical and empirical perspectives. Perhaps most importantly, we provide several suggestions for future research in the area of price risk given increasing risk on world agricultural markets due to both policy uncertainty and climate change.

Cryptocurrency literature is increasing rapidly nowadays. Particularly, the role of the cryptocurrency market as a risk management avenue has got the attention of researchers. However, it is an immature asset class and requires gaps in current literature for future research directions. This research provides a systematic review of the vast range empirical literature based on the cryptocurrency market as a risk management avenue against economic policy uncertainty (EPU). The review discovers that cryptocurrencies have mixed connectedness patterns with all national EPU therefore, the risk mitigation ability varies from country to country. The review finds that heterogeneous correlation patterns are due to the dependence of EPU on the policies and decisions usually taken by regulatory authorities of a particular country. Additionally, heterogeneous EPU requires heterogeneous solutions to deal with stock market volatility and economic policy uncertainty in different economies. Likewise, the divergent protocol and administration of currencies in the crypto market consequently vicissitudes the hedging and diversification performance against each economy. Many research lines can benefit investors, policymakers, fund managers, or portfolio managers. Therefore, the authors suggested future research avenues in terms of topics, data frequency, and methodologies.

Yoga is an ancient practice with Eastern roots that involves both physical postures (Asanas) and breathing techniques (Pranayamas). Yoga therapy for male sexual problems can effectively be treated through Yoga therapy, particularly with the help of Yoga poses and breathing exercises, Yoga has proven itself highly very effective in the treatment of a number of incurable and sometimes terminable diseases. Then again, Yoga's therapeutic effects are just a spin-off and supplementary. Yoga which has proved to be very effective in the treatment of many impossible and incurable diseases, the therapeutic effect of Yoga is only a by product and incidental. Problems related to sex can very well be handled with Yoga as most often these problems are more related to the mind than body. Either they are caused by lack of confidence or stress or fatigue or fear and very few times some physical cause is there. There is also a cognitive component focusing on meditation and concentration, which aids in achieving the goal of union between the self and the spiritual. Although numerous empirical studies have found a beneficial effect of Yoga on different aspects of physical and psychological functioning, claims of Yoga's beneficial effects on sexuality derive from a rich but no empirical literature. The goal of this article is to review the philosophy and forms of Yoga, to review the no empirical and (limited) empirical literatures linking Yoga with enhanced sexuality, and to propose some future research avenues focusing on Yoga as a treatment for sexual disorder.

The coronavirus pandemic (COVID-19) has had multilevel effects on non-COVID-19 health and health care, including deferral of routine cancer prevention and screening and delays in surgical and other procedures. Health and health care use has also been affected by pandemic-related loss of employer-based health insurance, food and housing disruptions, and heightened stress, sleep disruptions and social isolation. These disruptions are projected to contribute to excess non-COVID-19 deaths over the coming decades. At the same time municipalities, health systems and individuals are making changes in response to the pandemic, including modifications in the environmental to promote health, implementation of telehealth platforms, and shifts towards greater self-care and using remote platforms to maintain social connections. We used a multi-level biopsychosocial model to examine the available literature on the relationship between COVID-19-related changes and breast cancer prevention to identify current gaps in knowledge and identify potential opportunities for future research. We found that COVID-19 has impacted several aspects of social and economic life, through a variety of mechanisms, including unemployment, changes in health care delivery, changes in eating and activity, and changes in mental health. Some of these changes should be reduced, while others should be explored and enhanced.

It is a truism that a market economy cannot function without trust. We must be able to rely on other people to respect our property rights, and on our trading partners to keep their promises. The theory of economics is incomplete unless it can explain why economic agents often trust one another, and why that trust is often repaid. There is a long history of work in economics and philosophy which tries to explain the kinds of reasoning that people use when they engage in practices of trust: this work develops theories of trust. A related tradition in economics, sociology and political science investigates the kinds of social institution that reproduce whatever habits, dispositions or modes of reasoning are involved in acts of trust: this work develops theories of social capital. A recurring question in these literatures is whether a society which organizes its economic life through markets is capable of reproducing the trust on which those markets depend. In this paper, we look at these themes in relation to the writings of three eighteenth-century philosopher-economists: David Hume, Adam Smith, and Antonio Genovesi.

Purpose – The purpose of this paper is to provide a synthesis and evaluation of literature surrounding the job demands-resources (JD-R) model (Demerouti et al., 2001) in the first decade since its inception, with particular emphasis on establishing an evidence-based universal application towards different national and international work contexts. Design/methodology/approach – The study uses a systematic review approach following the stages suggested by Tranfield et al. (2003). Based on empirical data from 62 studies, the authors systematically analyse the application of the JD-R model and queries whether it is applicable outside merely domestic work contexts. Findings – The authors find convincing support for the JD-R model in different national contexts. However, the authors also found an absence of studies employing the JD-R model in cross-national settings. None of the empirical studies in the sample had explicitly considered the international context of today’s work environment or had clearly associated JD-R research with the IHRM literature. Research limitations/implications – Based on the wide acceptance of the JD-R model in domestic work contexts and the increased interest in work-related outcomes such as burnout and engagement in the IHRM literature, the study identifies a gap and suggests future research applying the JD-R model to international work and global mobility contexts. Originality/value – This study is the first to systematically assess the application of the JD-R model in domestic and international work contexts based on a systematic review of empirical literature in the first decade since the inception of the model. The study identifies a lack of internationally focussed JD-R studies and invites further empirical research and theoretical extensions.

The factors required to achieve sustainable economic growth in a country are debated for decades, and empirical research in this regard continues to grow. Given the relevance of the topic and the absence of a comprehensive, systematic literature review, we used bibliometric techniques to examine and document several aspects in the empirical literature related to growth, from 1991 to 2020. Five main results are worth highlighting: (a) the share of empirical articles on economic growth show a clear upward trend; (b) among all the groups of countries considered, the emerging economies (EEs) have received the most scientific attention; (c) the economic growth processes of the Latin American and Caribbean EEs have observed negligible scientific attention; (d) the very long-run studies comprise a residual share among the empirical literature on growth; (e) the extant empirical studies on economic growth have addressed mainly the impact of “macroeconomic conditions.” Our findings suggest there is a need to redirect the empirical growth agenda, so as to encourage more scientific attention devoted to the analysis of key determinants of economic growth in the very long run. There should also be increased scrutiny of the processes of economic growth in Latin American and Caribbean EEs

Persons with traumatic brain injuries (TBI) who have engaged in problematic or illegal sexual behavior present with complex assessment and intervention needs yet remain understudied within the empirical literature. In the current exploratory analysis, important differences in adaptive and clinical functioning, adverse childhood experiences, and criminal offense history are examined in 25 persons with previous brain injury, 118 persons with intellectual disability but no known TBI, and 103 persons with no history of brain injury or intellectual disability, all of whom have engaged in problematic sexual behavior and who were residing in secure forensic inpatient care. Group differences were examined using comparisons of means and chi-squares. Results highlight important differences in education and employment experiences, diagnostic presentation, exposure to childhood maltreatment, and justice system involvement and characteristics of their sexual offense victims. Associations with prior literature and future research directions are discussed.

The focus of this article is an employment of option contracts by economic agents when hedging a price risk in international trade of agriculture and food commodities. Despite a serious downturn in the world economy accompanied with major logistics and global value chains disruptions caused by Coronavirus disease in 2020, international agri-food trade demonstrates a sustainable growth supported by a constantly waxing demand due to continuous increase in population and improvement in living standards as well as a higher supply due to modern technological progress. It therefore implies that a comprehensive price risk management system should be introduced to avoid or minimize market participants’ exposure to potentially adverse future events. The article is devoted to the study of the key advantages of using options as an integrated element within such a system. Comparative analysis of future and option contracts is conducted to better understand their respective application depending on a risk profile of an event. The economic nature of options is presented from the perspective of a concept of price insurance that provides for an existence of a certain risk premium determined by market forces which is paid by economic agents to obtain such a price guarantee. Fundamental characteristics of an option contract as a financial derivative, its types and features, reason of usage according to the goals that economic agents, including e.g., powerful multinational enterprises (MNE), try to achieve depending on their specific market position are described. The article explains situations of economic agents, both producers and processors of agricultural commodities on the one hand (acting as hedgers) and speculators one the other hand (acting as such), being naturally long or naturally short as well as respective tactics based on options they adhere to with the aim of protecting their positions against unfavorable moves in market prices. Thus, the fact it refers to real scenarios of using options as price risk hedging tools which international traders can utilize when moving agricultural and food commodities globally, reinforces opinion that this article is of a significant practical importance.

In response to the lack of universal agreement about ‘What Works’ in probation supervision (Trotter, 2013) we undertook a Rapid Evidence Assessment of the empirical literature. Our analysis of research into the effect of probation supervision reducing reoffending included 13 studies, all of which employed robust research designs, originating in the USA, UK, Canada and Australia, published between 2006 and 2016. We describe the papers included in our review, and the meta-analyses of their findings. Overall, we found that the likelihood of reoffending was shown to be lower for offenders who had been exposed to some type of supervision. This finding should be interpreted cautiously however, given the heterogeneity of the studies. We suggest future research and methodological considerations to develop the evidence base concerning the effectiveness of probation supervision.
