Self-Regulation and Ego Control examines the physiological effects of depletion, the effects of psychological variables in self-control depletion effects, the role of motivational and goal states on self-control depletion effects, and a number of cognitive perspectives on self-control exertion. This insightful book begins with an introduction of self-control theories, ego depletion phenomena, and experimental examples of research in self-control, and concludes by delineating more inclusive and comprehensive models of self-regulation that can account for the full spectrum of findings from current research. In recent years, researchers have had difficulty identifying the underlying resources responsible for depletion effects. Moreover, further research has identified several psychological and motivational factors that can ameliorate depletion effects. These findings have led many to question assumptions of the dominant strength model and suggest that capacity limitations alone cannot account for the observed effects of depletion. Self-Regulation and Ego Control facilitates discourse across researchers from different ideological camps and advances more integrated views of self-regulation based on this research. Covers the neuropsychological evidence for depletion effects, highlighting the roles of reward, valuation, and control in self-regulation Reviews the roles of willpower, expectancies of mental energy change, and individual differences in the modulation of self-control exertion Highlights the effects of various states such as positive mood, power, implementation intentions, mindfulness, and social rejection as moderators of depletion Provides clarification of the distinctions between self-control in the context of goal-directed behavior versus related terms like self-regulation, executive control, and inhibition Details the overlap between mental and physical depletion, and the potential interplay and substitutability of resources Challenges the view that depletion reflects capacity limitations and includes newer models that take a more motivational account of resource allocation Facilitates discourse across researchers from different ideological camps within the field. Informs and enriches future research and advances more integrated views of self-regulation

This paper develops a model which explains how the creation of a futures clearinghouse allows traders to reduce default and economize on margin. We contrast the collateral necessary between bilateral partners with that required when multilateral netting occurs. Optimal margin levels are determined by the need to balance the deadweight costs of default against the opportunity costs of holding additional margin. Once created, it may (but need not) be optimal for the clearinghouse to monitor the financial condition of its members. If undertaken, monitoring will reduce the amount of margin required but need not have any effect on the probability of default. Once created, it becomes optimal for the clearinghouse membership to expel defaulting members. This reduces the probability of default. Our empirical tests suggest that the opportunity cost of margin plays an important role in margin determination. The relationship between volatility and margins indicates that participants face an upward sloping opportunity cost of margin. This appears to more than offset the effects that monitoring and expulsion would be expected to have on margin setting.

This lucidly written study is unique in that there is no book extant by an economic historian that discusses Talmudic economics in the light of modern economics. Its major focus is on the intricate debates, statements and principles that were forged by the Talmudic Rabbis. This ancient storehouse of learning includes a wealth of economic knowledge of modern sophistication. The book taps these "economic treasures" by way of analytic inquiry. The authors, both economic historians and economists, through their study of the original dialectics in the Talmud, were able to discern a wide range of macro- and micro-economic ideas of major significance. These concepts when viewed from either a contemporary or a modern perspective, display an extraordinary degree of insight and sophistication. Indeed, sections of the Talmud and the reflections of subsequent commentators on those passages, embody a wealth of economic thought that was later to become significant in the reasoning of political economists, or of their professional academic successors.

Whether we're buying a pair of jeans, ordering a cup of coffee, selecting a long-distance carrier, applying to college, choosing a doctor, or setting up a 401(k), everyday decisions—both big and small—have become increasingly complex due to the overwhelming abundance of choice with which we are presented. As Americans, we assume that more choice means better options and greater satisfaction. But beware of excessive choice: choice overload can make you question the decisions you make before you even make them, it can set you up for unrealistically high expectations, and it can make you blame yourself for any and all failures. In the long run, this can lead to decision-making paralysis, anxiety, and perpetual stress. And, in a culture that tells us that there is no excuse for falling short of perfection when your options are limitless, too much choice can lead to clinical depression. In The Paradox of Choice, Barry Schwartz explains at what point choice—the hallmark of individual freedom and self-determination that we so cherish—becomes detrimental to our psychological and emotional well-being. In accessible, engaging, and anecdotal prose, Schwartz shows how the dramatic explosion in choice—from the mundane to the profound challenges of balancing career, family, and individual needs—has paradoxically become a problem instead of a solution. Schwartz also shows how our obsession with choice encourages us to seek that which makes us feel worse. By synthesizing current research in the social sciences, Schwartz makes the counter intuitive case that eliminating choices can greatly reduce the stress, anxiety, and busyness of our lives. He offers eleven practical steps on how to limit choices to a manageable number, have the discipline to focus on those that are important and ignore the rest, and ultimately derive greater satisfaction from the choices you have to make.
