The effects of non-linear decay and consumer preferences are analyzed in a setting where optimal extraction of non-renewable resources is combined with stock externalities. The control is exercised via a corrective tax and the time horizon is divided into two periods: an initial phase with...

Several initiatives and auditors’ professional organizations have argued that assurance about the quality of information, processes, or compliance encompasses the future market base for the accounting profession. However, the market for assurance services is in its formative stage and not well...

In this paper some methods to determine the reporting delays for trades on the New York stock exchange are proposed and compared. The most successful method is based on a simple model of the quote revision process and a bootstrap procedure. In contrast to previous methods it accounts for...

Newspapers have an incentive to moderate their profile in order to gain a larger readership and thus higher advertising revenue. We show that this incentive is weakened both if readers are ad-haters and if they are ad-lovers.

This paper complements theoretical studies on the Kelly rule in evolutionary finance by studying a Darwinian model of selection and reproduction in which the diversity of investment strategies is maintained through genetic programming. We find that investment strategies which optimize long-term...

The extent to which a knowledge-intensive firm should induce cooperation between its employees is analyzed in a model of relational contracting between a firm (principal) and its employees (two agents). The agents can cooperate by helping each other, i.e. provide effort that increases the...

Increased activity of multinational firms exposes national corporate tax bases to cross-country profit shifting, but also leads to rising profitability of the corporate sector. We incorporate these two effects of economic integration into a simple political economy model where the median voter...

What drives extreme and rare economic events? Motivated by recent theory, and events in US subprime markets, we begin to open the black box of extremes. Specifically, we build a taxonomy of extremes, then extend standard economic analysis of extreme risk. First, we model the potentially relevant...

We investigate how multinational two-sided platform firms set their prices on intra firm transactions. Two-sided platform firms derive income from two customer groups that are connected through at least one positive network externality from one group to the other. A main finding is that even in...

Betas computed from returns based on investment cost rather than on market value, may give systematically inappropriate discount rates and numerically incorrect present values for nonzero NPVs and "mispriced" assets. The paper provides a self contained collection of a "baker's dozen" consistent...
