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.

Do financial derivatives enhance or impede innovation? We aim to answer this question by examining the relationship between equity options markets and standard measures of firm innovation. Our baseline results show that firms with more options trading activity generate more patents and patent citations per dollar of R&D invested. We then investigate how more active options markets affect firms' innovation strategy. Our results suggest that firms with greater trading activity pursue a more creative, diverse and risky innovation strategy. We discuss potential underlying mechanisms and show that options appear to mitigate managerial career concerns that would induce managers to take actions that boost short-term performance measures. Finally, using several econometric specifications that try to account for the potential endogeneity of options trading, we argue that the positive effect of options trading on firm innovation is causal.

This book of essays champions tort scholarship that puts judges at centre stage: what they do, how they understand their role, the heterogeneous reasons they give for their decisions, and their constitutional responsibility to identify and articulate the 'living' and 'evolving' common law. This is 'reflexive tort scholarship'. Reflexive tort scholars seek dialogue with Bench and Bar. Their approach is very different from the currently fashionable academic search for 'grand theories' that descriptively assert that tort law is fundamentally 'all about one thing', a unifying idea that alone explains and justifies the whole of tort law. This book illustrates the advantages and pay-offs of the reflexive style of scholarship by showing how it illuminates key features of tort law. The first essay contrasts the reflexive approach with the Grand Theory approach, while the second essay identifies a principle of tort law (the 'cooperative principle'), that is latent in the cases and that vindicates the value of collaborative human arrangements. Identifying this principle calls into question, in disputes between commercial parties, the reasoning used to support one of the most entrenched lines of authority in tort law - that based on the famous case of Hedley Byrne v Heller. The final essay deploys the reflexive method to argue that the iconic 'but-for' test of factual causation is inadequate and narrower than the concept actually utilized in the cases. Application of the method also prompts a reassessment of the 'scope of duty' concept and of the appropriate characterisation of the much-discussed decision in SAAMCO. These essays, based on the 2018 Clarendon Law Lectures given at Oxford University, clearly demonstrate the value of scholarship that 'takes the judges seriously'.

Institutional investors such as mutual funds and hedge funds play an important role in today's financial markets. This thesis consists of three essays which empirically study the behavior of active fund managers. In particular, the first essay investigates whether managers behave rationally or if some of them unconsciously make wrong investment decisions due to behavioral biases. The second essay examines whether some managers intentionally act to solely advance their own interests by strategically valuing the security positions in their portfolio. The third essay analyzes what the managers' education reveals about their investment behavior.

In the third edition of this international best seller, Lawrence Cunningham brings you the latest wisdom from Warren Buffett’s annual letters to Berkshire Hathaway shareholders. New material addresses: the financial crisis and its continuing implications for investors, managers and society; the housing bubble at the bottom of that crisis; the debt and derivatives excesses that fueled the crisis and how to deal with them; controlling risk and protecting reputation in corporate governance; Berkshire’s acquisition and operation of Burlington Northern Santa Fe; the role of oversight in heavily regulated industries; investment possibilities today; and weaknesses of popular option valuation models. Some other material has been rearranged to deepen the themes and lessons that the collection has always produced: Buffett’s “owner-related business principles” are in the prologue as a separate subject and valuation and accounting topics are spread over four instead of two sections and reordered to sharpen their payoff.

As in previous editions of The Essays of Warren Buffett, this one retains the architecture and philosophy of the original edition but adds selections from Warren Buffett's most recent annual shareholder letters. All the letters are woven together into a fabric that reads as a complete and coherent narrative of a sound business and investment philosophy. As an aid to all readers, and to enable readers of the previous editions to see what is new in this one, a disposition table at the end of the book shows the various places in this collection where selections from each year's letter appear. Footnotes throughout indicate the year of the annual report from which essays are taken. To avoid interrupting the narrative flow, omissions of text within excerpts are not indicated by ellipses or other punctuation. This new edition is called for not because anything has changed about the fundamentals of Buffett's sound business and investment philosophy but because articulation of that philosophy is always delivered in the context of contemporary events and business conditions so periodic updating is warranted to maintain its currency
