Markets and institutional fields: foundational concepts and a research agenda

We borrow the notion of field from institutional theory to think through how markets and their ‘outsides’–or at least one particular manifestation of an ‘outside’–stand in a dynamic and interactive relationship. We distinguish the field and the market in terms of issues versus exchange and identity versus position. We argue that the lack of clarity as to how fields and markets differ, relate, overlap, and are bounded, jeopardizes our ability to address important societal debates concerning the roles of markets within and across other areas of social life. It also hinders a consolidation of insights across different approaches to studying markets, even though researchers from different disciplines often address similar concerns. Key questions for which both conceptual and analytical clarity are essential include how markets and their ‘outsides’ (here: fields) intersect; whether and how diverse sets of actors interact, work, and migrate between fields and markets; and what dynamics may be observable between field and market. We provide four illustrative examples of field/market relationships and a theoretical, methodological, and empirical research agenda for future research into markets and their ‘outsides’.

Vortex lines in a cubic magnetic nanodot: structure and dynamics

Langevin simulations of cubic magnetic nanodots were performed using the Landau-Lifshitz equation with exchange and dipolar interactions. Vortices tend to organize as lines: we establish the structure and dynamics thereof for a large range of the dipolar versus exchange ratio d. These lines tend to be bent and twisted. For large values of the dipolar interaction, a complex network of vortex lines arises. Dynamics evidences low frequency collective gyrotropic motions of vortex lines which maintain their distance during motion.

Derivatives

Derivatives provide a means for shifting risk from one party to a counterparty that is more willing or better able to assume that risk. The counterparty's motivation for assuming that risk might be to manage its own risk or to enhance yield (make money). Derivatives transactions may be based on the value of foreign currency, U.S. Treasury bonds, stock indexes, or interest rates. There are four types of derivatives contracts: forwards, futures, swaps, and options. This chapter discusses the following: counterparty credit risk, over-the-counter versus exchange-traded derivatives, shifting risk, types of derivatives, reduction of counterparty risk, suitability as hedging instruments, distinction between forwards and futures, foreign exchange forwards and futures, options, characteristics of swaps, and credit derivatives.
