Book Description
This dissertation is composed of three chapters. All three deal with topics in development economics. The first chapter examines the effects on village institutions of introducing formal financial institution options into the village. The second addresses the effects of government policy on educational investment and crime. The third tests the explanatory power of various explanations of the gender gap in math test scores. The first chapter examines the effects of a transition from a ``traditional'' economy based on an uncertain source of income, with risk fully insured away by one's neighbors in a social network through costly network ties, to a ``modern'' economy in which some agents have access to partial insurance at a lower cost. A theoretical model is used to show that village social networks can break down as some members of the village no longer need the insurance the social network provides, producing a reduction in welfare (if the costs of reducing moral hazard are not too high) for at least some individuals and possibly the village as a whole. This loss of welfare can occur even when networks provide other benefits to those belonging to them and is likely to be heterogeneous, depending on the opportunities and networks available to individuals. This paper tests these predictions using Indonesian data to examine the effect of a change in the banking institutions available to a community on the strength of social networks (measured by community participation) and welfare (measured by household expenditure and by child health). The analysis finds that changing financial institution availability in general does not influence community participation or welfare, but that financial institutions that primarily serve certain groups do relatively reduce the welfare of households not in those groups, which is consistent with the hypotheses generated by the model. Crime is an important feature of economic life in many countries, especially in the developing world. Crime distorts many economic decisions because it acts like an unpredictable tax on earnings. In particular, the threat of crime may influence people's willingness to invest in schooling or physical capital. The second chapter explores the questions "What influence do crime rates and levels of investment have on one another?" and "How do government policies affect the relationship between investment and crime?" by creating a simple structural model of crime and educational investment and attempting to fit this model to Mexican data. A method of simulated moments procedure is used to estimate parameters of the model and the estimated parameters are then used to carry out policy simulations. The simulations show that increasing spending on police or increasing the severity of punishment reduces crime but has little effect on educational investment. Increased educational subsidies increase educational investment but reduce crime only slightly. Thus, one type of policy is insufficient to accomplish the goals of both reducing crime and increasing education. The third chapter is joint work with Prashant Bharadwaj, Giacomo De Giorgi, and Christopher Neilson. Boys tend to have better performances than girls in mathematical testing; in particular, there are significantly more boys than girls among high achievers and the score distribution appears to have a longer right tail for boys. We confirm such results on several low- and middle-income countries. In particular we find that the gender gap is already present by age 10 and substantially increases by age 14 and 15. We propose and try to test a series of explanations for such a gap: (i) parental investment, (ii) ability, (iii) school resources, (iv) individual investment and effort (not tested directly), (v) competitive environment, and (vi) cultural norms. We conclude that none of our proposed explanations can account for a substantial portion of the gap.

Book Description
This first volume in a three-volume exposition of Shubik's vision of "mathematical institutional economics" explores a one-period approach to economic exchange with money, debt, and bankruptcy. This is the first volume in a three-volume exposition of Martin Shubik's vision of "mathematical institutional economics"--a term he coined in 1959 to describe the theoretical underpinnings needed for the construction of an economic dynamics. The goal is to develop a process-oriented theory of money and financial institutions that reconciles micro- and macroeconomics, using as a prime tool the theory of games in strategic and extensive form. The approach involves a search for minimal financial institutions that appear as a logical, technological, and institutional necessity, as part of the "rules of the game." Money and financial institutions are assumed to be the basic elements of the network that transmits the sociopolitical imperatives to the economy. Volume 1 deals with a one-period approach to economic exchange with money, debt, and bankruptcy. Volume 2 explores the new economic features that arise when we consider multi-period finite and infinite horizon economies. Volume 3 will consider the specific role of financial institutions and government, and formulate the economic financial control problem linking micro- and macroeconomics.

Book Description
In his later work, Freud proposed that the human psyche could be divided into three parts: Id, ego and super-ego. Freud discussed this model in the 1920 essay Beyond the Pleasure Principle, and fully elaborated upon it in The Ego and the Id (1923), in which he developed it as an alternative to his previous topographic schema (i.e., conscious, unconscious and preconscious). The id is the completely unconscious, impulsive, childlike portion of the psyche that operates on the "pleasure principle" and is the source of basic impulses and drives; it seeks immediate pleasure and gratification. Freud acknowledged that his use of the term Id (das Es, "the It") derives from the writings of Georg Groddeck. The super-ego is the moral component of the psyche, which takes into account no special circumstances in which the morally right thing may not be right for a given situation. The rational ego attempts to exact a balance between the impractical hedonism of the id and the equally impractical moralism of the super-ego; it is the part of the psyche that is usually reflected most directly in a person's actions. When overburdened or threatened by its tasks, it may employ defense mechanisms including denial repression, undoing, rationalization, repression, and displacement. This concept is usually represented by the "Iceberg Model". This model represents the roles the Id, Ego, and Super Ego play in relation to conscious and unconscious thought. Freud compared the relationship between the ego and the id to that between a charioteer and his horses: the horses provide the energy and drive, while the charioteer provides direction.

Book Description
This clear-thinking collection brings together 25 of Daly s essays, speeches, reviews and testimonials from the past decade. . . as a whole they provide a useful masterclass on the principles of ecological economics. Daly s vision, as well as his frustration with mainstream economists refusal to engage with his arguments, comes through loud and clear. New Scientist It s hard to imagine ecological economics without the numerous and profound contributions of Herman Daly. These papers reveal the consistency of his analysis and clarity of exposition that have made him one of the most influential economists of his generation. Because of Herman Daly we have a much better understanding of how economies relate to the environment, why so much is wrong with this relationship and what must be done to fix it. Peter Victor, York University, Canada This thrilling compilation outlines the origins of the young discipline of ecological economics by the intellectual leader of the movement, Herman Daly. He recounts how, as a member of the recently demoted environment department at the World Bank, he integrated ecology with economics during his six years in the bowels of the beast. Herman lucidly and compellingly combines common sense with profound understanding of both economics and ecology to arrive at sustainable solutions to the global problematique. Herman s rigorous yet compassionate solutions to climate change, peak oil, globalization vs. internationalization, poverty reduction, and the unsung concept of scale leading to uneconomic growth, are precisely what we need to prevent the current liquidation of our beautiful world. This book will galvanize you into the action we need so much. Robert Goodland, Environmental adviser, World Bank Group, 1978 2001 In this book, written in crystal clear style, Herman Daly reiterates the main points of his analysis and vision, he praises some teachers (John Ruskin, Frederick Soddy, Nicholas Georgescu-Roegen, Kenneth Boulding), he fearlessly attacks some adversaries in the World Bank and MIT, and he offers some advice to the government of his own country, to the Russian Duma, and especially to OPEC that, if followed, would change the world very much for the better. Finally, on a different line of thought, he interrogates conservation biologists on their reasons for wanting to keep biodiversity since, as biologists, they claim that evolution has no particular purpose. Why not let the Sixth Great Extinction run its course? In other words, science cannot provide an ethics of conservation, which Herman Daly finds in religion more than in democratization deliberations. Joan Martinez-Alier, Universitat Autonòma de Barcelona, Spain Ecological Economics and Sustainable Development comprises a carefully chosen selection of some 25 articles, speeches, congressional testimonies, reviews, and critiques from the last ten years of Herman Daly s ever-illuminating work. This book seeks to identify the blind spots and errors in standard growth economics, alongside the corrections that ecological economics offers to better guide us toward a sustainable economy one with deeper biophysical and ethical roots. Under the general heading of sustainability and ecological economics, many specific topics are here brought into relation with each other. These include: limits to growth; full-world versus empty-world economics; uneconomic growth; definitions of sustainability; peak oil; steady-state economics; allocation versus distribution versus scale issues; non-enclosure of rival goods and enclosure of non-rival goods; production functions and the laws of thermodynamics; OPEC and Kyoto; involuntary resettlement and development; resource versus value-added taxation; globalization versus internationalization; immigration; climate change; and the philosophical presuppositions of policy, including the policies suggested in connection with the topics above. This fascinating work will appeal to scholars and academics of ecol

Book Description
This collection of Michael Grossman’s most important papers adds essential background and depth to his work on economic determinants of public health. Each of the book’s four sections includes an introduction that contextualizes the issues and addresses the larger stakes of his work. An afterword discusses the significance of Grossman’s approach for subsequent research on health economics, as well as the work others have done to advance and extend his innovative perspective. Determinants of Health explains how the economic choices people make influence health and health behaviors. It begins with a section on the theoretical underpinnings and empirical results of Grossman’s groundbreaking health economics model, first introduced in the 1970s, followed by essays on the relationship between health and schooling; determinants of infant health, with a special emphasis on public policies and programs; and the economics of unhealthy behaviors. Grossman treats health as a form of human capital. He shows that public policies and programs that determine the price and availability of key inputs have critical effects on outcomes ranging from birth weight and infant mortality to cigarette smoking, alcohol abuse, illegal drug use, and obesity. Grossman’s approach has led to a major stream of literature in the field, sparking contributions by the world’s leading health economists, including Joseph Newhouse, Jonathan Gruber, Amy Finkelstein, Michael Greenstone, and David Cutler. His clarity on the role that economics play in people’s good and bad health choices is immensely valuable to the debate over how we legislate and spend on health.
