A Generalized Bachelier Formula for Pricing Basket and Spread Options

In this paper we propose a closed-form pricing formula for European basket and spread options. Our approach is based on approximating the risk-neutral probability density function of the terminal value of the basket using a Gauss-Hermite series expansion around the Gaussian density. The new method is quite general as it can be applied for a basket with a large number of assets and…

A review of empirical resarch on the design and impact of regulation in the banking sector

We review existing empirical research on the design and impact of regulation in the banking sector. The impact of each individual piece of regulation may inexorably depend on the set of regulations already in place, the characteristics of the banks involved (from their size or ownership structure to operational idiosyncrasies in terms of capitalization levels or risk taking behavior…

The perennial challenge to counter Too-Big-to-Fail in banking: Empirical evidence from the new international regulation dealing with Global Systemically Important Banks

This paper provides evidence on how the new international regulation on Global Systemically Important Banks (G-SIBs) impacts the market value of large banks. We analyze the stock price reactions for the 300 largest banks from 52 countries across 12 relevant regulatory announcement and designation events. We observe that the new regulation negatively affects the value of the newly…

Bank loan announcements and borrower stock returns before and during the recent financial crisis

The impact of U.S. bank loan announcements on the stock prices of the corporate borrowers
has been decreasing during the two last decades with estimated two-day cumulative abnormal returns slipping from almost 200 basis points in the beginning of the 1980s to close to zero by the turn of the Century. We estimate excess returns before and after the onset of the most recent…

A Random Forests Based Performance Ratio for Regulatory Asset Portfolio Management and Optimization

The following paper proposes a portfolio performance measure to optimize, mostly bond asset portfolios usually held for regulatory purposes from a risk focused perspective. The measure is based on variations of the proximity measure introduced by the Random Forests framework, leading to a proximity based performance ratio. The proximities are modeled using a recursive conditional…

Scalable high-dimensional dynamic stochastic economic modeling

We present a highly parallelizable and flexible computational method to solve high-dimensional stochastic dynamic economic models. Solving such models often requires the use of iterative methods, like time iteration or dynamic programming. By exploiting the generic iterative structure of this broad class of economic problems, we propose a parallelization scheme that favors hybrid…

Liquidity Management in Banking: What is the Role of Leverage?

This paper examines potential impacts of banks' leverage on their incentives to manage their liquidity. We analyze a model where banks control their liquidity risk by managing their liquid asset positions. In the basic framework, a model with a single bank, where the possibility of selling long-term assets when in need of liquidity is not taken into account, we find that the…

The motives for financial complexity: An empirical investigation

This paper investigates the motives for financial complexity by focusing on a large market of investment products exclusively targeted to households. We develop a robust measure of complexity by performing a text analysis of the term sheets of 55,000 retail structured products issued in 17 European countries since 2002. We first find that the complexity of structured products has…

More than money: exploring the role of investment advisors for sustainable investing

Purpose – Investment advisors play a significant role in financial markets, yet the determinants of their behavior have not been explored in detail. The purpose of this paper is to explore the determinants of how actively advisors communicate about sustainable investing with their clients, and differences in the preferences of advisors compared to investors. Design/methodology/…

Collateral smile

We analyze the impact of funding costs and margin requirements on index options traded on the CBOE. Assuming differential borrowing and lending rates, we derive no-arbitrage bounds for European options. We show that funding costs and the CBOE’s margin requirements lead to a price increase, which translates into skew and smile patterns for implied volatility curves even under constant…

Detecting abnormal trading activities in option markets

We develop an econometric method to detect "abnormal trades" in option markets, i.e., trades which are not driven by liquidity motives. Abnormal trades are characterized by unusually large increments in open interest, trading volume, and option returns, and are not used for option hedging purposes. We use a multiple hypothesis testing technique to control for false…

Social interaction at work

Stock market investment decisions of individuals are positively correlated with that of co-workers. Sorting of unobservably similar individuals to the same workplaces is unlikely to explain our results, as evidenced by the investment behavior of individuals that move between plants. Purchases made under stronger co-worker purchase activity are not associated with higher returns.…

A Theory of the Stakeholder Corporation

There is a widely held view within the general public that large corporations should act in the interests of a broader group of agents than just their shareholders (the stake- holder view). This paper presents a framework where this idea can be justified. The point of departure is the observation that a large firm typically faces endogenous risks that may have a significant…

What is 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…
