Framing effects are everywhere. An estate tax looks very different
to a death tax. Gun safety seems to be one thing and gun control
another. Yet, the consensus from decision theorists, finance
professionals, psychologists, and economists is that
frame-dependence is completely irrational. This book challenges
that view. Some of the toughest decisions we face are just clashes
between different frames. It is perfectly rational to value the
same thing differently in two different frames, even when the
decision-maker knows that these are really two sides of the same
coin. Frame It Again sheds new light on the structure of moral
predicaments, the nature of self-control, and the rationality of
co-operation. Framing is a powerful tool for redirecting public
discussions about some of the most polarizing contemporary issues,
such as gun control, abortion, and climate change. Learn effective
problem-solving and decision-making to get the better of difficult
dilemmas.
This book, based on the author's Clarendon Lectures in Finance,
examines the empirical behavior of corporate default risk. A new
and unified statistical methodology for default prediction, based
on stochastic intensity modeling, is explained and implemented with
data on U.S. public corporations since 1980. Special attention is
given to the measurement of correlation of default risk across
firms. The underlying work was developed in a series of
collaborations over roughly the past decade with Sanjiv Das,
Andreas Eckner, Guillaume Horel, Nikunj Kapadia, Leandro Saita, and
Ke Wang. Where possible, the content based on methodology has been
separated from the substantive empirical findings, in order to
provide access to the latter for those less focused on the
mathematical foundations.
A key finding is that corporate defaults are more clustered in time
than would be suggested by their exposure to observable common or
correlated risk factors. The methodology allows for hidden sources
of default correlation, which are particularly important to include
when estimating the likelihood that a portfolio of corporate loans
will suffer large default losses. The data also reveal that a
substantial amount of power for predicting the default of a
corporation can be obtained from the firm's "distance to default,"
a volatility-adjusted measure of leverage that is the basis of the
theoretical models of corporate debt pricing of Black, Scholes, and
Merton. The findings are particularly relevant in the aftermath of
the financial crisis, which revealed a lack of attention to the
proper modelling of correlation of default risk across firms.
The concept of rationality is a common thread through the human and
social sciences -- from political science to philosophy, from
economics to sociology, and from management science to decision
analysis. But what counts as rational action and rational behavior?
Jose Luis Bermudez explores decision theory as a theory of
rationality. Decision theory is the mathematical theory of choice
and for many social scientists it makes the concept of rationality
mathematically tractable and scientifically legitimate.
Yet rationality is a concept with several dimensions and the theory
of rationality has different roles to play. It plays an
action-guiding role (prescribing what counts as a rational solution
of a given decision problem). It plays a normative role (giving us
the tools to pass judgment not just on how a decision problem was
solved, but also on how it was set up in the first place). And it
plays a predictive/explanatory role (telling us how rational agents
will behave, or why they did what they did).
This controversial but accessible book shows that decision theory
cannot play all of these roles simultaneously. And yet, it argues,
no theory of rationality can play one role without playing the
other two. The conclusion is that there is no hope of taking
decision theory as a theory of rationality.
Introduces a powerful new approach to financial risk modeling with
proven strategies for its real-world applications The 2008 credit
crisis did much to debunk the much touted powers of Value at Risk
(VaR) as a risk metric. Unlike most authors on VaR who focus on
what it can do, in this book the author looks at what it cannot. In
clear, accessible prose, finance practitioners, Max Wong, describes
the VaR measure and what it was meant to do, then explores its
various failures in the real world of crisis risk management. More
importantly, he lays out a revolutionary new method of measuring
risks, Bubble Value at Risk, that is countercyclical and offers a
well-tested buffer against market crashes. * Describes Bubble VaR,
a more macro-prudential risk measure proven to avoid the
limitations of VaR and by providing a more accurate risk exposure
estimation over market cycles * Makes a strong case that analysts
and risk managers need to unlearn our existing "science" of risk
measurement and discover more robust approaches to calculating risk
capital * Illustrates every key concept or formula with an
abundance of practical, numerical examples, most of them provided
in interactive Excel spreadsheets * Features numerous real-world
applications, throughout, based on the author s firsthand
experience as a veteran financial risk analyst
Employees are increasingly asked to make sophisticated decisions
about their pension and healthcare plans. Yet recent research shows
that the decisions 'real' people make are often not those of the
careful and well-informed economic agent conventionally portrayed
in economic research. Rather, decision-makers tend to operate with
flawed information and make some of the most critical financial
decisions of their lives lacking a full understanding of the
options before them and the implications of their decisions.
Pension Design and Structure explores the assumptions behind
commonly-held theories of retirement decision-making, in order to
draw out the consequences of frontier research in behavioral
finance and economics for those interested in better design and
structure of retirement pensions. Using large datasets newly
provided by financial service firms and real-world experiments,
this volume tests the hypotheses of this research. This is the
first book to explore the implications of behavioral finance
research for pensions and retirement studies. The authors blend
cutting-edge research from several fields including Finance,
Economics, Management, Sociology, and Psychology. The book will be
of interest to pension plan participants and sponsors, financial
service groups responsible for pensions, and retirement system
regulators.
Die hier durchgefuhrte Querschnittsstudie evaluiert erstmalig, ob
Schulen sich erfolgreich eigenstandig - wie bildungspolitisch
gefordert -, in sogenannte "problemloesende" Organisationseinheiten
transformieren koennen, um ihren Unterricht im Rahmen der
Schulentwicklung kontinuierlich weiterzuentwickeln. Die Ergebnisse
dieser Studie stellen hierbei vor allem die Nachhaltigkeit von
Schulentwicklung in Frage, da weder die Lehrpersonen noch
Schulleitungsmitglieder an den evaluierten Berufsfachschulen der
Meinung waren, dass Schulentwicklung den Unterricht und die
beruflichen Fahigkeiten der Einzellehrperson uberhaupt beeinflusst.
Begrundet liegt dieses Ergebnis u.a. in der von den Schulen
vorgenommenen Implementierungsstrategie. So wird das
Lehrerkollegium allgemein zu wenig in Entscheidungsprozesse
involviert und beispielsweise nur unzureichend uber den
Zielerreichungsgrad und Massnahmen abgeschlossener
Schulentwicklungsprojekte informiert.
