Information Processing on the Swiss Stock Market
We conduct an event study to investigate the processing of information and the existence of insider trading on the Swiss stock market. Although Swiss laws are less restrictive than those of other countries, we find the empirical evidence for systematic insider trading before the publication of information to be fairly weak. Even for information producing large positive or negative...

Valuing Employee Stock Options: Does the Model Matter?
In this numerical analysis of models for valuing employee stock options, the focus is on the impact of a model on the resulting option prices and the sensitivity of pricing differences between models with respect to changes in the parameters. For most models, the price reduction relative to standard options is uniquely determined by the expected life of the option. In fact, with the...

Die Bedeutung der Körperschaftssteuer: Theoretische Überlegungen, die internationale Entwicklung und die Schweiz
Taking into account that international tax competition is going stronger, first arguments in favour of abolishing corporate income taxation or even any capital income taxation are presented. Second, the arguments in favour of capital income taxation and especially of corporate income taxation are discussed. There, we also consider those arguments which explain differences in the...

Stress That Doesn't Pay: The Commuting Paradox
People spend more and more time commuting and often find it a burden.nAccording to economics, the burden of commuting is chosen when compensated eithernon the labor or on the housing market so that individuals' utility is equalized. However, inna direct test of this strong notion of equilibrium, we find that people with longerncommuting time report systematically lower...

A Learning Theory for the Harsanyi's Doctrine in Repeated Games
This paper investigates simultaneous learning about both nature and others' actions in repeated games, and identifies a set of sufficient conditions assuring that equilibrium actions converge to a Nash equilibrium.nPlayers have each an utility function over infinite histories continuous for the product topology. Nature' drawing after any history can depend on any past...

When Are Market Crashes Driven by Speculation?
A natural conjecture is that speculative trade disappears when individual beliefs become correct through learning. Sandroni in [22] gives a counterexample in an economy with sunspots. We generalizenSandroni's result by showing that the conjecture holds for economies with complete markets only. We consider a standard finite-horizon General Equilibrium model with complete markets...

Existence and Global Attractivity of Stable Solutions in Neural Networks
The present paper shows that a sufficient condition for the existence of a stable solution to an autoregressive neural network model is the continuity and boundedness of the activation function of the hidden units in the multi layer perceptron (MLP). In addition, uniqueness of a stable solution is ensured by global lipschitzness and some conditions on the parameters of the system. In...

Why the Olympics have three prizes and not just one
There are at least two reasons why multiple prizes can be optimal in symmetric imperfectly discriminating contests. First, the introduction of multiple prizes reduces the standard deviation of contestants' effort in asymmetric equilibria, when the majority of contestants actively participate in competition. Second, the introduction of multiple prizes may increase the aggregate (...

Are stock markets really like beauty contests? Empirical evidence of higher order belief's impact on asset prices
The goal of this paper is to assess, for the first time, the empirical impact of "Keynes’ beauty contest", or "higher order beliefs", on asset price volatility. The paper shows that heterogeneous expectations induce higher order beliefs and that heterogeneous expectation asset pricing models theoretically generate more volatility than rational expectation models....

Start-up Investment With Scarce Venture Capital Support
Venture capitalists, representing informed capital, screen, monitor and advise start-up entrepreneurs. The paper reports three new results on venture capital (VC) finance and the evolution of the VC industry. First, there is an optimal VC portfolio size with a trade-off between the number of companies and the value of managerial advice. Second, advice tends to be diluted when the...

Progressive Taxation, Moral Hazard, and Entrepreneurship
This paper considers the general equilibrium and welfare effects of a linear progressive income tax with entrepreneurship and moral hazard. A competitive intermediation sector diversifies risk associated with entrepreneurial activity, but full risk consolidation is prevented by moral hazard. Since effort is not observable, risk bearing of entrepreneurs is required for incentive...

Taxation and Venture Capital Backed Entrepreneurship
In recent years, venture capital has increasingly become a factor in the financing of new firms. We examine how the value of mature firms determines the incentives of entrepreneurs to start up new firms and of venture capitalists to finance and advise them. We examine how capital gains taxes as well as subsidies to start-up costs of new firms affect venture capital backed...

Yes, Managers Should be Paid Like Bureaucrats
"Corporate scandals, reflected in excessive management compensation and fraudulent accounts, cause great damage. Agency theory’s insistence to link the compensation of mangers and directors as closely as possible to firm performance is a major reason for these scandals.nThey cannot be overcome by improving variable pay for performance as selfish extrinsicnmotivation is...

Mergers under Asymmetric Information Is there a Lemons Problem?
We analyze a Bayesian merger game under two-sided asymmetric information about firm types. We show that the standard prediction of the lemons market model–if any, only low-type firms are traded–is likely to be misleading: Merger returns, i.e. the difference between pre- and post-merger profits, are not necessarily higher for low-type firms. This has two implications. First, under...

What if the Fed Had Been an Inflation Nutter?
A structural rational expectations model of U.S. monetary policy is used to make a counterfactual experiment of a strongly inflation averse Federal Reserve Bank. Results for U.S. interest rates, output, and inflation over 1965-1999 are discussed.
