TL;DR: Laffont and Martimort as mentioned in this paper focus on the principal-agent model, the "simple" situation where a principal, or company, delegates a task to a single agent through a contract, the essence of management and contract theory.
Abstract: Economics has much to do with incentives--not least, incentives to work hard, to produce quality products, to study, to invest, and to save. Although Adam Smith amply confirmed this more than two hundred years ago in his analysis of sharecropping contracts, only in recent decades has a theory begun to emerge to place the topic at the heart of economic thinking. In this book, Jean-Jacques Laffont and David Martimort present the most thorough yet accessible introduction to incentives theory to date. Central to this theory is a simple question as pivotal to modern-day management as it is to economics research: What makes people act in a particular way in an economic or business situation? In seeking an answer, the authors provide the methodological tools to design institutions that can ensure good incentives for economic agents. This book focuses on the principal-agent model, the "simple" situation where a principal, or company, delegates a task to a single agent through a contract--the essence of management and contract theory. How does the owner or manager of a firm align the objectives of its various members to maximize profits? Following a brief historical overview showing how the problem of incentives has come to the fore in the past two centuries, the authors devote the bulk of their work to exploring principal-agent models and various extensions thereof in light of three types of information problems: adverse selection, moral hazard, and non-verifiability. Offering an unprecedented look at a subject vital to industrial organization, labor economics, and behavioral economics, this book is set to become the definitive resource for students, researchers, and others who might find themselves pondering what contracts, and the incentives they embody, are really all about.

TL;DR: In this paper, the authors provide a comprehensive treatment of the microeconomic theory of banking and finance, with a focus on four important topics: the theory of two-sided markets and its implications for the payment card industry; "non-price competition" and its effect on the competition-stability tradeoff and the entry of new banks; the transmission of monetary policy and the effect of the credit market of capital requirements for banks; and the theoretical foundations of banking regulation, which have not yet led to a significant parallel development of economic modeling.
Abstract: Over the last thirty years, a new paradigm in banking theory has overturned economists' traditional vision of the banking sector. The asymmetric information model, extremely powerful in many areas of economic theory, has proven useful in banking theory both for explaining the role of banks in the economy and for pointing out structural weaknesses in the banking sector that may justify government intervention. In the past, banking courses in most doctoral programs in economics, business, or finance focused either on management or monetary issues and their macroeconomic consequences; a microeconomic theory of banking did not exist because the Arrow-Debreu general equilibrium model of complete contingent markets (the standard reference at the time) was unable to explain the role of banks in the economy. This text provides students with a guide to the microeconomic theory of banking that has emerged since then, examining the main issues and offering the necessary tools for understanding how they have been modeled. This second edition covers the recent dramatic developments in academic research on the microeconomics of banking, with a focus on four important topics: the theory of two-sided markets and its implications for the payment card industry; "non-price competition" and its effect on the competition-stability tradeoff and the entry of new banks; the transmission of monetary policy and the effect on the functioning of the credit market of capital requirements for banks; and the theoretical foundations of banking regulation, which have been clarified, although recent developments in risk modeling have not yet led to a significant parallel development of economic modeling. Praise for the first edition:"The book is a major contribution to the literature on the theory of bankingand intermediation. It brings together and synthesizes a broad range ofmaterial in an accessible way. I recommend it to all serious scholars andstudents of the subject. The authors are to be congratulated on a superbachievement." -- Franklin Allen, Nippon Life Professor of Finance and Economics, WhartonSchool, University of Pennsylvania "This book provides the first comprehensive treatment of the microeconomicsof banking. It gives an impressive synthesis of an enormous body ofresearch developed over the last twenty years. It is clearly written and apleasure to read. What I found particularly useful is the great effort thatXavier Freixas and Jean-Charles Rochet have taken to systematicallyintegrate the theory of financial intermediation into classicalmicroeconomics and finance theory. This book is likely to become essentialreading for all graduate students in economics, business, and finance." -- Patrick Bolton, Barbara and David Zalaznick Professor of Business, Columbia University Graduate School of Business "The authors have provided an extremely thorough and up-to-date survey ofmicroeconomic theories of financial intermediation. This work manages to beboth rigorous and pleasant to read. Such a book was long overdue and shouldbe required reading for anybody interested in the economics of banking andfinance." -- Mathias Dewatripont, Professor of Economics, ECARES, Universit

TL;DR: In this paper, the authors compare two forms of crowdfunding: entrepreneurs solicit individuals either to pre-order the product or to advance a fixed amount of money in exchange for a share of future profits (or equity).
Abstract: With crowdfunding, an entrepreneur raises external financing from a large audience (the "crowd"), in which each individual provides a very small amount, instead of soliciting a small group of sophisticated investors. This article compares two forms of crowdfunding: entrepreneurs solicit individuals either to pre-order the product or to advance a fixed amount of money in exchange for a share of future profits (or equity). In either case, we assume that "crowdfunders" enjoy "community benefits" that increase their utility. Using a unified model, we show that the entrepreneur prefers pre-ordering if the initial capital requirement is relatively small compared with market size and prefers profit sharing otherwise. Our conclusions have implications for managerial decisions in the early development stage of firms, when the entrepreneur needs to build a community of individuals with whom he or she must interact. We also offer extensions on the impact of quality uncertainty and information asymmetry.

TL;DR: In this article, the authors focus on the former constraint and consider the case of a single principal (the monopolist) and show that, under a separability assumption, strong conclusions can be drawn about the nature of optimal incentive schemes.
Abstract: Recent theoretical research on principal-agent relationships has emphasized incentive problems that arise when the parties involved are constrained by either asymmetric information or their inability to monitor each other's actions. Here we concentrate on the former constraint and consider the case of a single principal (the monopolist). The main contribution is to show that, under a separability assumption, strong conclusions can be drawn about the nature of optimal incentive schemes. Although the primary focus is on optimal quantity discounts in a monopolized market, the results also shed light on related topics, such as optimal income taxation and commodity bundling.

TL;DR: In this article, a theory of hedonic prices is formulated as a problem in the economics of spatial equilibrium in which the entire set of implicit prices guides both consumer and producer locational decisions in characteristics space.
Abstract: A class of differentiated products is completely described by a vector of objectively measured characteristics. Observed product prices and the specific amounts of characteristics associated with each good define a set of implicit or "hedonic" prices. A theory of hedonic prices is formulated as a problem in the economics of spatial equilibrium in which the entire set of implicit prices guides both consumer and producer locational decisions in characteristics space. Buyer and seller choices, as well as the meaning and nature of market equilibrium, are analyzed. Empirical implications for hedonic price regressions and index number construction are pointed out.

INTRODUCTION One would suppose that in any economic system where equality is valued, progressive income taxation would be an important instrument of policy. Even in a highly socialist economy, where all who work are employed by the State, the shadow price of highly skilled labour should surely be considerably greater than the disposable income actually available to the labourer. In Western Europe and America, tax rates on both high and low incomes are widely and lengthily discussed3: but there is virtually no relevant economic theory to appeal to, despite the importance of the tax. Redistributive progressive taxation is usually related to a man's income (or, rather, his estimated income). One might obtain information about a man's income-earning potential from his apparent I.Q., the number of his degrees, his address, age or colour: but the natural, and one would suppose the most reliable, indicator of his income-earning potential is his income. As a result of using men's economic performance as evidence of their economic potentialities, complete equality of social marginal utilities of income ceases to be desirable, for the tax system that would bring about that result would completely discourage unpleasant work. The questions therefore arise what principles should govern an optimum income tax; what such a tax schedule would look like; and what degree of inequality would remain once it was established. The problem seems to be a rather difficult one even in the simplest cases. In this paper, I make the following simplifying assumptions: (1) Intertemporal problems are ignored. It is usual to levy income tax upon each year's income, with only limited possibilities of transferring one year's income to another for tax purposes. In an optimum system, one would no doubt wish …

TL;DR: In this article, the authors show that a tax imposed on the seller of a monopolized article may lead to an actual lowering of the price to the buyer, and that the result of a tax is to cheapen the untaxed as well as the taxed commodities.
Abstract: That a tax imposed on the seller of a monopolized article may lead to an actual lowering of the price to the buyer has been shown by F. Y. Edgeworth.2 His example was of a railway supplying two classes of passenger service at different prices and, unhindered by governmental interference, setting its rates so as to make its own profit a maximum. When the company is compelled to pay a tax on each first-class ticket, it finds it profitable, in Edgeworth’s example, to reduce rates on both classes of accommodations. Regarding this paradoxical conclusion, Professor Seligman writes:3 The mathematics which can show that the result of a tax is to cheapen the untaxed as well as the taxed commodities will surely be a grateful boon to the perplexed and weary secretaries of the treasury and ministers of finance throughout the world!
