Multivariate Stochastic Volatility Models: Bayesian Estimation And Model Comparison, Jun Yu, Renate Meyer

Research Collection School Of Economics

In this paper we show that fully likelihood-based estimation and comparison of multivariate stochastic volatility (SV) models can be easily performed via a freely available Bayesian software called WinBUGS. Moreover, we introduce to the literature several new specifications which are natural extensions to certain existing models, one of which allows for time varying correlation coefficients. Ideas are illustrated by fitting, to a bivariate time series data of weekly exchange rates, nine multivariate SV models, including the specifications with Granger causality in volatility, time varying correlations, heavy-tailed error distributions, additive factor structure, and multiplicative factor structure. Empirical results suggest that the …

Asymmetric Response Of Volatility: Evidence From Stochastic Volatility Models And Realized Volatility, Jun Yu

Research Collection School Of Economics

This paper examines the asymmetric response of equity volatility to return shocks. We generalize the news impact function (NIF), originally introduced by Engle and Ng (1993) to study asymmetric volatility under the ARCH-type models, to be applicable to both stochastic volatility (SV) and ARCH-type models. Based on the generalized concept, we provide a unified framework to examine asymmetric properties of volatility. A new asymmetric volatility model, which nests both ARCH and SV models and at the same time allows for a more flexible NIF, is proposed. Empirical results based on daily index return data support the classical asymmetric SV model …

La Ley De Concursos Mercantiles En México: Algunas Reflexiones A Cuatro Años De Su Entrada En Vigor [The New Bankruptcy Law In Mexico: Some Reflections Since Enacted 4 Years Ago], Armando R. Lopez-Velasco, Leonardo E. Torre Cepeda

School of Economics and Finance Faculty Publications

• La función de una ley de quiebras consiste en maximizar el valor de empresas que llegan a caer en situaciones de insolvencia. Su buen funcionamiento es esencial para la operación eficiente del mercado de crédito y, por ende, para el crecimiento y desarrollo sostenido de la economía.

• Una ley de quiebras debe ser modificada cuando se presentan, simultáneamente: (i) una restricción crediticia que impide que empresas potencialmente rentables reciban los fondos necesarios para financiar sus inversiones, (ii) retrasos en el cierre de empresas que deben ser liquidadas y (iii) costos elevados por retrasar la reorganización o liquidación de …

Strict Liability For Gatekeepers: A Reply To Professor Coffee, Frank Partnoy

University of San Diego Law and Economics Research Paper Series

This article responds to a proposal by Professor John C. Coffee, Jr. for a modified form of strict liability for gatekeepers. Professor Coffee’s proposal would convert gatekeepers into insurers, but cap their insurance obligations based on a multiple of the highest annual revenues the gatekeepers recently had received from their wrongdoing clients. My proposal, advanced in 2001, would allow gatekeepers to contract for a percentage of issuer damages, after settlement or judgment, subject to a legislatively-imposed floor. This article compares the proposals and concludes that a contractual system based on a percentage of the issuer’s liability would be preferable to …

Encumbered Shares, Shaun Martin, Frank Partnoy

University of San Diego Law and Economics Research Paper Series

The fundamental assumptions in the law and economics literature about shareholder voting and the one-share/one-vote rule are flawed. The classic view is that share ownership is necessary and sufficient to create voting rights and that such rights should be directly proportional to share ownership. We demonstrate that this assumption is unfounded, both for shares that are “economically encumbered” (held by shareholders who are not pure residual claimants; e.g., a shareholder who owns one share and is also short one or more shares) as well as shares that are “legally encumbered” (held or associated with more than one shareholder; e.g., shares …

Theory And Practice Of Competition Advocacy At The Ftc, James C. Cooper, Paul A. Pautler, Todd J. Zywicki

George Mason University School of Law Working Papers Series

This article was prepared as part of a recent symposium celebrating the Ninetieth Anniversary of the founding of the Federal Trade Commission. In addition, fall 2004 marks the Thirtieth Anniversary of a pivotal moment in the establishment of the modern advocacy program at the FTC, Chairman Lewis Engman’s speech on the economic burden that inefficient transportation regulation policies were imposing on the American economy. Although the FTC has been involved in advocacy activities since its founding, Engman’s speech symbolized a new aggressiveness on the part of the FTC in using its expertise to work with other governmental actors at all …

Does The Tax Law Discriminate Against The Majority Of American Children: The Downside Of Our Progressive Rate Structure And Unbalanced Incentives For Higher Education?, Lester B. Snyder

University of San Diego Law and Economics Research Paper Series

Our graduate income tax structure provides an incentive to shift income to lower-bracket family members. However, some parents have much more latitude to shift income to their children than do others. Income derived from services and private business-by far the majority of American income-is less favored than income derived from publicly traded securities. The rationale given for this discrimination is that parents in services or private business, as opposed to those in securities, do not actually part with control of their property. This article explores these tax broader (yet subtle) tax benefits and their impact on the majority of children …

Rents, Dissipation, And Lost Treasures With N Parties, Giuseppe Dari-Mattiacci, Eric Langlais, Francesco Parisi

George Mason University School of Law Working Papers Series

The rent-seeking literature is unanimous on the fact that, in a rent-seeking context, the rent dissipation increases with the number of potential participants. In this paper we analyze the participants' choice to enter the game and their levels of efforts. We show that the usual claim - that the total dissipation approaches the entire value of the rent - applies only when participants are relatively weak. In the presence of strong competitors, the total dissipation actually decreases, since participation in the game is less frequent. We also consider the impact of competitors' exit option, distinguishing between redistributive rent-seeking and productive …

Economic Systems Of Oecd Nations: Impact And Evolution, Frederic L. Pryor

Economics Faculty Works

This essay argues that economic systems should be defined in terms of clusters of complementary institutions. To show how such an approach can be carried out, I use a cluster analysis technique and data on forty different economic institutions in OECD nations to isolate four quite different economic systems. After specifying the most important institutional clusters in each system, I then examine what impact these economic systems have on various indicators of economic performance. Finally, I show how such an approach allows particular evolutionary patterns of the systems to be analyzed.

Obesity And Advertising Policy, Todd J. Zywicki, Debra Holt, Maureen Ohlhausen

George Mason University School of Law Working Papers Series

It is clear that Americans are getting fatter, both adults and children. This development has led some to call for a ban on food advertising directed at children. There are numerous practical and constitutional difficulties with such a policy. This article poses a more fundamental question - even if feasible, would restricting food advertising do anything to reduce obesity or even slow its trends? The article also considers whether the social costs of banning advertising could outweigh the social benefits of such an action.

This article provides a review of the literature on the fundamental causes of the American obesity …

Shelter Strategies For The Urban Poor: Idiosyncratic And Successful, But Hardly Mysterious, Jerry Kalarickal, Robert M. Buckley

Economics - All Scholarship

In 1986 the World Bank prepared a strategy for low-income housing in developing countries. This work grew out of the Bank's efforts to support the urban poor through an extensive housing assistance program that was launched by Bank President McNamara's speech on urban poverty. By that time, the Bank had provided more than $4 billion of such assistance, and had undertaken an extensive research effort to design support for that lending. Much has changed since that time, not only in the way the Bank provides shelter assistance, more than doubling its support since that review, but also in the changing …

The Effects Of Malpractice Tort Reform On Defensive Medicine, Katherine D. Hennesy, Heather M. O'Neill

Business and Economics Faculty Publications

Positive defensive medicine occurs when physicians order additional tests or procedures primarily to avoid malpractice liability. This paper shows the degree of defensive medicine occurring across states is related to the malpractice environment in the states. As the environment changes due to malpractice tort reform, defensive medicine practices also change. This paper shows the existence of positive defensive medicine and how it adds to total health care expenditures for head trauma victims in 23 states in 2000. Moreover, given different malpractice environments across states, we witness variations in defensive medicine practices leading to differences in health care expenditures.

Land Values As A Source Of Local Government Finance, Tom Dunne

Books/Book Chapters

Funding local government has been a permanent feature of debates about public policy in Ireland and Many feel that the balance of power between local and central government is weighted too much in

This paper suggests that the concept of economic rent, on which the justification for property taxes rests and its relevance to the property market in a modern, economically successful and urbanised Ireland, needs to be vented, discussed and debated.

The proposition is that if a greater understanding was created about the economic characteristics of landed property both value capture and local property taxes would achieve greater public …

Educational Investments In A Dual Economy, Andrew G. Mude, Christopher B. Barrett, John G. Mcpeak, Cheryl R. Doss

Economics - All Scholarship

This paper presents a simple two-period, dual economy model in which migration options may affect the informal financing of educational investments. When credit contracts are universally available and perfectly enforceable, spatially varied returns to human capital have no effect on educational investment patterns. But when financial markets are incomplete and informal mechanisms subject to imperfect contract enforcement must fill the breach, spatial inequality in infrastructure or other attributes that affect the returns to education create spatial differentiation in educational lending and consequently, in educational attainment. Although migration options can increase the returns to education, they can also choke off the …

On The Evolution Of Comparative Advantage In Matching Models, Eric O'N. Fisher, Vikas Kakkar

Economics

This paper examines whether comparative advantage is the long-run outcome of an evolutionary process in the open economy. It formalizes the notion that natural selection eliminates inefficient firms and thus leads to stable and perhaps efficient patterns of world trade. Instead of assuming the existence of a Walrasian auctioneer, we study two simple matching processes that coordinate trade between firms. Our central result is that specialization according to comparative advantage, with the larger country possibly incompletely specialized, is the unique evolutionarily stable state of the world economy.

The Effects Of Labor Strikes On Consumer Demand: A Re-Examination Of Major League Baseball, Victor Matheson

Economics Department Working Papers

Previous research has concluded that the 1981 and 1994/95 Major League Baseball (MLB) strikes have caused short-term losses in attendance but have not resulted in any long-term effects on attendance. While total attendance at MLB games following the 1994/95 strike has recovered to its pre-strike levels, this has been done only through the construction of new stadiums at an unprecedented pace which cannot continue into the future. After accounting for stadium effects, average MLB baseball attendance has dropped significantly since the 1994/95 strike.

The Past, Present And Future Of Community Reinvestment Act (Cra): A Historical Perspective, Akm Rezaul Hossain

Economics Working Papers

This paper takes a historical approach to understand the evolution of one of the most controversial banking regulations in recent history, the Community Reinvestment Act (CRA) of 1978 and its effects on access to credit and banking services to community borrowers. The paper lays out the historical milieu of credit markets in the late seventies and describes the early justification of this legislation. The paper explores the implementation of the act through regulations on lending institutions and the effects of the regulations on depository lenders and community borrowers. Detailed description of the reactions to CRA regulations by different parties involved …

The Folk Theorem In Dynastic Repeated Games, Luca Anderlini, Dino Gerardi, Roger Lagunoff

Cowles Foundation Discussion Papers

A canonical interpretation of an infinitely repeated game is that of a “dynastic” repeated game: a stage game repeatedly played by successive generations of finitely-lived players with dynastic preferences. These two models are in fact equivalent when the past history of play is observable to all players. In our model all players live one period and do not observe the history of play that takes place before their birth, but instead receive a private message from their immediate predecessors. Under very mild conditions, when players are sufficiently patient, all feasible payoff vectors (including those below the minmax) can be sustained …

Distribution And Politics: A Brief History And Prospect, John E. Roemer

Cowles Foundation Discussion Papers

A brief, historical review of the study of the interdependency between politics and economic distribution is offered. While the impact of economic interests on politics has been acknowledged for thousands of years, and the impact of politics on distribution for hundreds, it is only in the last thirty years that formal models of the interdependency between economic distribution and politics have been formulated. A general model of political-economic equilibrium is proposed, in which political competition and economic distribution jointly determine each other. Several examples are given. The author proposes that political economy, conceived of as studying this process of joint …

Competitive Experimentation With Private Information, Giuseppe Moscarini, Francesco Squintani

Cowles Foundation Discussion Papers

We study a winner-take-all R&D race where firms are privately informed about the uncertain arrival rate of the invention. Due to the interdependent-value nature of the problem, the equilibrium displays a strong herding effect that distinguishes our framework from war-of-attrition models. Nonetheless, equilibrium expenditure in R&D is sub-optimal when the planner is sufficiently impatient. Pessimistic firms prematurely exit the race, so that the expected discounted amount of R&D activity is inefficiently low. This result stands in contrast to the overinvestment in research that is typical of winner-take-all R&D races without private information. We conclude that secrecy in R&D inefficiently slows …

On The Nonparametric Identification Of Nonlinear Simultaneous Equations Models: Comment On B. Brown (1983) And Roehrig (1988), C. Lanier Benkard, Steven T. Berry

Cowles Foundation Discussion Papers

This note revisits the identification theorems of B. Brown (1983) and Roehrig (1988). We describe an error in the proofs of the main identification theorems in these papers, and provide an important counterexample to the theorems on the identification of the reduced form. Specifically, contrary to the theorems, the reduced form of a nonseparable simultaneous equations model is not identified even under the assumptions of those papers. We conclude the note with a conjecture that it may be possible to use classical exclusion restrictions to recover some of the key implications of the theorems.

Toward An Economic Theory Of Dysfunctional Identity, Hanming Fang, Glenn C. Loury

Cowles Foundation Discussion Papers

We advance a novel choice-theoretic model of “identity” based on the notions of categories and narratives. Identity is conceived as a matter of “reflexive perception” — how people understand themselves. Choosing an identity is equivalent to making a generalization about one’s past that highlights the most salient aspects of experience. When many individuals make a common choice in this regard, they embrace a collective identity which is dysfunctional if it is Pareto dominated by an alternative self-classificatory schema. Using a simple multi-stage risk sharing game, we explore conditions under which dysfunctional collective identities might be expected to emerge.

Rationality Of Belief. Or: Why Bayesianism Is Neither Necessary Nor Sufficient For Rationality, Itzhak Gilboa, Andrew Postlewaite, David Schmeidler

Cowles Foundation Discussion Papers

Economic theory reduces the concept of rationality to internal consistency. The practice of economics, however, distinguishes between rational and irrational beliefs. There is therefore an interest in a theory of rational beliefs, and of the process by which beliefs are generated and justified. We argue that the Bayesian approach is unsatisfactory for this purpose, for several reasons. First, the Bayesian approach begins with a prior, and models only a very limited form of learning, namely, Bayesian updating. Thus, it is inherently incapable of describing the formation of prior beliefs. Second, there are many situations in which there is not sufficient …

Axiomatization Of An Exponential Similarity Function, Antoine Billot, Itzhak Gilboa, David Schmeidler

Cowles Foundation Discussion Papers

An agent is asked to assess a real-valued variable y based on certain characteristics x = ( x 1 ,…, x m ), and on a database consisting of n observations of ( x 1 ,…, x m ,y). A possible approach to combine past observations of x and y with the current values of x to generate an assessment of y is similarity-weighted averaging. It suggests that the predicted value of y , y s n +1, be the weighted average of all previously observed values y i , where the weight of y i is the similarity between …

Modeling Party Competition In General Elections, John E. Roemer

Cowles Foundation Discussion Papers

We survey critically the brief history of modeling party competition in general elections, beginning with the Hotelling-Downs model with a unidimensional policy space, and the Wittman model with endogenous parties, to the multi-dimensional citizen-candidate and PUNE models. Some applications of the newer models are discussed.
