The Law and Economics of Hedge Funds: Financial Innovation and Investor Protection Houman B. Shadab t Abstract: A persistent theme underlying contemporary debates about financial regulation is how to protect investors from the growing complexity of financial markets, new risks, and other changes brought about by financial innovation. Increasingly relevant to this debate are the leading innovators of complex investment strategies known as hedge funds. A hedge fund is a private investment company that is not subject to the full range of restrictions on investment activities and disclosure obligations imposed by federal securities laws, that compensates management in part with a fee based on annual profits, and typically engages in the active trading offinancial instruments. Hedge funds engage in financial innovation by pursuing novel investment strategies that lower market risk (beta) and may increase returns attributable to manager skill (alpha). Despite the funds' unique costs and risk properties, their historical performance suggests that the ultimate result of hedge fund innovation is to help investors reduce economic losses during market downturns. -

In this introductory paper, we make the linkage between the use of big data and Econophysics, a research field which uses a large amount of data and deals with complex systems. Different approaches such as power laws and complex networks are discussed, as possible frameworks to analyze complex phenomena that could be studied using Econophysics and resorting to big data. Keywords: big data; complexity; networks; stock markets; power laws 1. Introduction Big data has become a very popular expression in recent years, related to the advance of technology which allows, on the one hand, the recovery of a great amount of data, and on the other hand, the analysis of that data, benefiting from the increasing computational capacity of devices. -
An Introduction to Financial Econometrics
An introduction to financial econometrics Jianqing Fan Department of Operation Research and Financial Engineering Princeton University Princeton, NJ 08544 November 14, 2004 What is the financial econometrics? This simple question does not have a simple answer. The boundary of such an interdisciplinary area is always moot and any attempt to give a formal definition is unlikely to be successful. Broadly speaking, financial econometrics is to study quantitative problems arising from finance. It uses sta- tistical techniques and economic theory to address a variety of problems from finance. These include building financial models, estimation and inferences of financial models, volatility estimation, risk management, testing financial economics theory, capital asset pricing, derivative pricing, portfolio allocation, risk-adjusted returns, simulating financial systems, hedging strategies, among others. Technological invention and trade globalization have brought us into a new era of financial markets. Over the last three decades, enormous number of new financial products have been created to meet customers’ demands. For example, to reduce the impact of the fluctuations of currency exchange rates on a firm’s finance, which makes its profit more predictable and competitive, a multinational corporation may decide to buy the options on the future of foreign exchanges; to reduce the risk of price fluctuations of a commodity (e.g. lumbers, corns, soybeans), a farmer may enter into the future contracts of the commodity; to reduce the risk of weather exposures, amuse parks (too hot or too cold reduces the number of visitors) and energy companies may decide to purchase the financial derivatives based on the temperature. An important milestone is that in the year 1973, the world’s first options exchange opened in Chicago. -

CHALLENGES IN MACRO-FINANCE MODELING DON H. KIM∗ Abstract. This paper discusses various challenges in the specification and implemen- tation of “macro-finance” models in which macroeconomic variables and term structure variables are modeled together in a no-arbitrage framework. I classify macro-finance models into pure latent-factor models (“internal basis models”) and models which have observed macroeconomic variables as state variables (“external basis models”), and examine the underlying assumptions behind these models. Particular attention is paid to the issue of unspanned short-run fluctuations in macro variables and their poten- tially adverse effect on the specification of external basis models. I also discuss the challenge of addressing features like structural breaks and time-varying inflation uncer- tainty. Empirical difficulties in the estimation and evaluation of macro-finance models are also discussed in detail. 1. introduction In recent years there has been much interest in developing “macro-finance models”, in which yields on nominal bonds are jointly modeled with one or more macroeconomic variables within a no-arbitrage framework. -
Reconstructing the Great Recession
Reconstructing the Great Recession Michele Boldrin, Carlos Garriga, Adrian Peralta-Alva, and Juan M. Sánchez This article uses dynamic equilibrium input-output models to evaluate the contribution of the con- struction sector to the Great Recession and the expansion preceding it. Through production inter- linkages and demand complementarities, shifts in housing demand can propagate to other economic sectors and generate a large and sustained aggregate cycle. According to our model, the housing boom (2002-07) fueled more than 60 percent and 25 percent of employment and GDP growth, respectively. The decline in the construction sector (2007-10) generates a drop in total employment and output about half of that observed in the data. In sharp contrast, ignoring interlinkages or demand comple- mentarities eliminates the contribution of the construction sector. (JEL E22, E32, O41) Federal Reserve Bank of St. Louis Review, Third Quarter 2020, 102(3), pp. 271-311. https://doi.org/10.20955/r.102.271-311 1 INTRODUCTION With the onset of the Great Recession, U.S. employment and gross domestic product (GDP) fell dramatically and then took a long time to return to their historical trends. There is still no consensus about what exactly made the recession so deep and the subsequent recovery so slow. In this article we evaluate the role played by the construction sector in driving the boom and bust of the U.S. economy during 2001-13. The construction sector represents around 5 percent of total employment, and its share of GDP is about 4.5 percent. Mechanically, the macroeconomic impact of a shock to the con- struction sector should be limited by these figures; we claim it is not. -
Course Information Sheet for Entry in 2018-19 Msc in Law and Finance
24/10/2017 MSc in Law and Finance | University of Oxford Course Information Sheet for entry in 2018-19 MSc in Law and Finance About the course The MSc in Law and Finance is taught jointly by the Law Faculty and the Saïd Business School. It will provide you with an advanced interdisciplinary understanding of economic and nancial concepts and their application to legal topics. The MSc combines a highly analytic academic core with tailor-made practical applications derived from collaboration with professional and regulatory organisations. There are two core nance courses, Finance and First Principles of Financial Economics, a core interdisciplinary course, Law and Economics of Corporate Transactions, and one or more elective courses in law. There are also pre-sessional courses in maths and nancial reporting. In addition to these core MLF courses, students selecting the Law Stream will take two law electives from a tailored list of about 10 law courses that are available to students on the Bachelor of Civil Law (BCL). The list of law electives comprises courses that are business law-oriented and thus are intended to complement both each other and the MLF course as a whole. In taking these electives, you will be joined by students taking the Law Faculty's other taught graduate courses, the BCL and the Magister Juris (MJur). MLF students can also select the Finance Stream. If you select this option, you will take only one law elective. In lieu of the second law elective, you will take a mandatory nance course, Corporate Valuation, in the second term and one nance elective in the third term. -

Microfoundations?
MICROFOUNDATIONS? J.E King* Department of Economics and Finance La Trobe University Victoria 3086 Australia [email protected] September 2008 *Discussions with Peter Kriesler first set me thinking about this question; I am also grateful to Sheila Dow, Mike Howard, Tee-Hee Jo, Fred Lee, Ian MacDonald, Kurt Rothschild, Michael Schneider and Tony Thirlwall for comments on an earlier draft of this paper. None of them is implicated in errors of fact or judgement. 1 Abstract It is widely believed by both mainstream and heterodox economists that macroeconomic theory must be based on microfoundations (MIFs). I argue that this belief is unfounded and potentially dangerous. I first trace the origins of MIFs, which began in the late 1960s as a project and only later hardened into a dogma. Since the case for MIFs is derived from methodological individualism, which itself an offshoot of the doctrine of reductionism, I then consider some of the relevant literature from the philosophy of science on the case for and against reducing one body of knowledge to another, and briefly discuss the controversies over MIFs that have taken place in sociology, political science and history. Next I assess a number of arguments for the need to provide macrofoundations for microeconomics. While rejecting this metaphor, I suggest that social and philosophical foundations (SPIFs) are needed, for both microeconomics and macroeconomics. I conclude by rebutting the objection that ‘it’s only a word’, suggesting instead that foundational metaphors in economics are positively misleading and are therefore best avoided. Convergence with the mainstream on this issue has gone too far, and should be reversed. -
Paul Krugman Gets His ‘Nobel’
“A maximization-and-equilibrium kind of guy”: Paul Krugman gets his ‘Nobel’ Paper for the 11th Conference of the Association for Heterodox Economics, on the theme “Heterodox Economics and Sustainable Development, 20 years on”, Kingston University, London, 9-12 July 2009 Hugh Goodacre Senior Lecturer, University of Westminster Affiliate Lecturer, Birkbeck College, University of London Teaching Fellow, University College London Abstract. Paul Krugman’s ‘new economic geography’ currently enjoys a high profile due to his recent Nobel award for contributions to the economics of geography and trade; it also conveniently focuses a number of wider issues regarding the relations of economics with its neighboring social science disciplines. Krugman describes himself as “ basically a maximization-and- equilibrium kind of guy…, quite fanatical about defending the relevance of standard economic models in many situations.” In contrast, the incumbent sub-discipline of economic geography has long played host to a zealous critique of such ‘standard’, that is, neoclassical models, and has fiercely defended its pluralistic traditions of research against the ‘monism’, or ‘economics imperialism’, of invasive initiatives such as Krugman’s. This paper surveys the lively polemical literature between these two very different kinds of guys on how to address the question of the global pattern of distribution of economic wealth and activity. It is argued that neither side in the interdisciplinary polemic has focussed sufficiently sharply on the political economy and intellectual and historical legacy of the colonial era. In conclusion, it is suggested that only by rectifying this shortcoming can the current inter- disciplinary standoff be shifted away from narrowly theoretical and methodological issues onto terrain where a more telling blow to economics imperialism can be made than the geographical critique has hitherto managed to deliver. -
