Local volatility of volatility for the VIX market

Following a trend of sustained and accelerated growth, the VIX futures and options market has become a closely followed, active and liquid market. The standard stochastic volatility models—which focus on the modeling of instantaneous variance—are unable to fit the entire term structure of VIX futures as well as the entire VIX options surface. In contrast, we propose to model directly...

Bank bailout menus

We study bailouts of banks that suffer from debt overhang problems and have private information about the quality of their assets-in-place and new investment opportunities. Menus of bailout plans are used as a screening device. Constrained optimality involves overcapitalization and nonlinear pricing, with worse types choosing larger bailouts. When investment opportunities follow the...

Investment competence and advice seeking

This paper evaluates individuals’ ability to avoid investment mistakes and analyzes how investment competence is related to the propensity to seek or rely on professional advice. To address these issues, we use novel survey data collected from a representative sample of Swiss households. We find that investment competence is characterized by significant age and gender gaps, and that...

The impact of monetary policy on stock market bubbles and trading behavior: evidence from the lab

We investigate the effect of monetary policy on stock market bubbles and trading behavior in experimental asset markets. We introduce the possibility of investing in interest bearing bonds to the widely used laboratory asset market design of Smith et al. (1988). Treatment groups face a variable interest rate policy which depends on asset prices, while control groups are subjected to...

Die Umwandlung des Kapitalismus und seine Finanzdurchdringung

Die Dynamik, Unübersichtlichkeit und Unabgeschlossenheit einer Krise, wie wir sie derzeit in der Wirtschaft, besonders der Finanzwirtschaft, erleben, führen einzelwissenschaftliche Theorien und Studien an eine innere Komplexitätsgrenze. Der Band versammelt die Ergebnisse der zweijährigen Zusammenarbeit von Ökonomen, Literaturwissenschaftlern, Theologen, Finanzwissenschaftlern und...

Using adaptive sparse grids to solve high-dimensional dynamic models

We present a flexible and scalable method to compute global solutions of high-dimensional non-smooth dynamic models. Within a time-iteration setup, we interpolate policy functions using an adaptive sparse grid algorithm with piecewise multi-linear (hierarchical) basis functions. As the dimensionality increases, sparse grids grow considerably slower than standard tensor product grids...

Time-varying mixture GARCH models and asymmetric volatility

The class of mixed normal conditional heteroskedastic (MixN-GARCH) models, which couples a mixed normal distributional structure with GARCH-type dynamics, has been shown to offer a plausible decomposition of the contributions to volatility, as well as excellent out-of-sample forecasting performance, for financial asset returns. In this paper, we generalize the MixN-GARCH model by...

What's Beneath the Surface? Option Pricing with Multifrequency Latent States

We introduce a tractable class of non-ane price processes with multifrequency stochastic volatil- ity and jumps. The specications require few xed parameters and deliver fast option pricing. One key ingredient is a tight link between jumps and volatility regimes, as asset pricing theory suggests. Empirically, the model matches implied volatility surfaces and their dynamics with- out...

Is there Swissness in investment competence?

Based on a large international survey we analyze how German- French- and Italian-speaking Swiss differ in their investment decision behavior and competence as compared to their closest neighbors abroad speaking the same language. Although language may be closer to the individual self than the country of residence, we find that there are greater similarities in the decision...

"Know the Competitor, Know Thyself?" First Evidence from Banks in Emerging Europe

How best to measure banking competition? The empirical banking literature typically resorts to well-known concentration measures such as the Herfindahl–Hirschman index, or performance indicators like the Lerner or Boone indexes. While these have their merits, none of them explicitly takes into account that banks may actively compete with some banks but not with others. This chapter...

Corporate leverage and firm-bank relationships: A secular perspective

The depth of the recent financial crisis is often attributed to excessively high leverage of corporations and banks. This column analyses corporate leverage in the long-run, and in particular the shift from bilateral to multilateral firm-bank relationships in the UK. This shift is related to the firms’ use of debt finance, and subsequently to their increased leverage

A critique of shareholder value maximization

The majority of academic economists share the view that a corporation should serve the exclusive interests of its shareholders (shareholder value maximization). This view is fi rmly grounded on the extension, by Arrow (1953) and Debreu (1959) of the two welfare theorems to production economies with uncertainty and complete markets. This paper considers a variant of the Arrow-Debreu...

Taming systemically important financial institutions

We model a Systemically Important Financial Institution (SIFI) that is too big (or too interconnected) to fail. Without credible regulation and strong supervision, the shareholders of this institution might deliberately let its managers take excessive risk. We propose a solution to this problem, showing how insurance against systemic shocks can be provided without generating moral...
