Legal and economic aspects of best execution in the context of the Markets in Financial Instruments Directive (MiFID)

This paper explores the implications for investment firms and clients that arise out of an interpretation of the Market in Financial Instruments Directive (MiFID) best execution requirements from a law and economics perspective. While best execution is often framed as a matter of investor protection, research on market microstructure suggests that there is, in fact, an efficiency…

Computational aspects of prospect theory with asset pricing applications

We develop an algorithm to compute asset allocations for Kahneman and Tversky’s (Econometrica, 47(2), 263–291, 1979) prospect theory. An application to benchmark data as in Fama and French (Journal of Financial Economics, 47(2), 427–465, 1992) shows that the equity premium puzzle is resolved for parameter values similar to those found in the laboratory experiments of Kahneman and…

Strategic asset allocation and market timing: a reinforcement learning approach

We apply the recurrent reinforcement learning method of Moody, Wu, Liao, and Saffell (1998) in the context of the strategic asset allocation computed for sample data from US, UK, Germany, and Japan. It is found that the optimal asset allocation deviates substantially from the fixed-mix rule. The investor actively times the market and he is able to outperform it consistently over the…

Bias-adjusted estimation in the ARX(1) model

A new point estimator for the AR(1) coefficient in the linear regression model with arbitrary exogenous regressors and stationary AR(1) disturbances is developed. Its construction parallels that of the median--unbiased estimator, but uses the mode as a measure of central tendency. The mean--adjusted estimator is also considered, and saddlepoint approximations are used to lower the…

Saddlepoint approximations for the doubly noncentral t distribution

Closed-form approximations for the density and cumulative distribution function of the doubly noncentral t distribution are developed based on saddlepoint methods. They exhibit remarkable accuracy throughout the entire support of the distribution and are vastly superior to existing approximations. An application in finance is considered which capitalizes on the enormous increase in…

Trend derivatives: pricing, hedging, and application to executive stock options

Both institutional and private investors often have only limited flexibility in timing their investment decision. They look for investments that will ideally be independent of the timing decision. In this article, a new class of derivative products whose payoff is linked to the trend of the underlying instrument is introduced. By linking the trend to the payoff, the timing of the…

Corporate financial reporting and disclosure. A behavioral finance perspective

Managers' information disclosure to firm's outsiders plays an essential role for mitigating information asymmetry and agency problems. The main objective of this thesis is to analyze the managers' reporting incentives in a broader context, while considering the preferences of behavioural investors and the active role of financial analysts as target setters in…

Why have exchange-traded catastrophe instruments failed to displace reinsurance?

In spite of the fact that they can draw on a larger, more liquid and more diversiedpool of capital than the equity of reinsurance companies, nancial markets have failedto displace reinsurance as the primary risk-sharing vehicle for natural catastropherisk. We show that this failure can be explained by dierences in information gatheringincentives between nancial markets and…

An Analysis of Shareholder Agreements

Shareholder agreements govern the relations among shareholders in privately held firms, such as joint ventures and venture capital-backed companies. We provide an economic explanation for key clauses in such agreements 14namely, put and call options, tag-along and drag-along rights, demand and piggy-back rights, and catch-up clauses. In a dynamic moral hazard setting, we show that…

The Role of Knowhow Acquisition in the Formation and Duration of Joint Ventures

We analyze the role of knowhow acquisition in the formation and duration of joint ventures. Two parties become partners in a joint venture to benefit from each other’s knowhow. Joint operations provide each party with the opportunity to acquire part of its partner’s knowhow. A party’s increased knowhow provides the impetus for the dissolution of the joint venture. We characterize the…

Why government bonds are sold by auction and corporate bonds by posted-price selling

When information is costly, a seller may wish to prevent prospective buyers from acquiring information, for the cost of information acquisition ultimately is borne by the seller. A seller can achieve the desired prevention through posted-priceselling, by offering prospective buyers a discount. No such prevention is possible in the case of an auction. We establish the result that the…

The great capitol hill baby sitting co-op: Anecdote or evidence for the optimum quantity of money?

This paper studies a centralized market with idiosyncratic uncertainty and money as a medium of exchange from a theoretical as well as an experimental perspective. In our model, prices are fixed and markets are cleared by rationing. We prove the existence of stationary monetary equilibria and of an optimum quantity of money. The rational solution of our model, which is based on the…

The earnings game with behavioral investors

This paper studies how the investors' attitude towards earnings surprises a®ects the managers' incentives to manipulate earnings in an intertemporal context, where the consensus forecast of the analysts is not exogenously given but determined by the strategic interaction between the analysts and the managers. Our analysis shows that given the asymmetric investors'…

Why does implied risk aversion smile?

Implied risk aversion estimates reported in the literature are strongly U-shaped. This article explores different potential explanations for these “smile” patterns: (i) preference aggregation, both with and without stochastic volatility and jumps in returns, (ii) misestimation of investors’ beliefs caused by stochastic volatility, jumps, or a Peso problem, and (iii) heterogeneous…

Approximate generalizations and computational experiments

In this paper I demonstrate how one can generalize finitely many examples to statements about (infinite) classes of economic models. If there exist upper bounds on the number of connected components of one-dimensional linear subsets of the set of parameters for which a conjecture is true, one can conclude that it is correct for all parameter values in the class considered, except for…
