Because of a long time frame, irreversible and specific investments, incomplete contracts andpolitical constraints, it is generally difficult for governments to commit themselves in a credibleway to a fixed petroleum tax regime. Many controversial renegotiations and tightenings of suchsystems...

Topical issues in petroleum tax design are in this chapter discussed by means of a tax model for anet income tax system (Norway) and a representative PSA regime. We analyse the entire lifecycle of a typical petroleum project, i.e., the exploration decision is included. Many petroleumtax systems...

Shortages of rigs and personnel have encouraged creativity in designing incentive contracts in thedrilling sector. In particular for oil service contracts, since those companies have the most directcontrol of drilling efficiency. A large variety of contract types are in use, including within...

The oil companies are concerned to replace the petroleum reserves they producein order to maintain their future level of activity. Booked reserves alsorepresent an important input when analysts value these companies. Many producercountries want to control their own resources, a goal which can...

Ambiguity, also called Knightian or model uncertainty, is a key feature in financial modeling. A recent paper by Maccheroni et al. (2004) characterizes investorpreferences under aversion against both risk and ambiguity. Their result shows that these preferences can be numerically represented in...

Robust utility functionals arise as numerical representations of investor preferences, when the investor is uncertain about the underlying probabilistic model and averse against both risk and model uncertainty. In this paper, we study the duality theory for the problem of maximizing the robust...

This paper makes three contributions to our understanding of the price discovery process in currencymarkets. First, it provides evidence that this process cannot be the familiar one based on adverse selectionand customer spreads, since such spreads are inversely related to a trade’s likely...

Using panel data on large Polish firms this paper examines the relationship between corporatecontrol structures, sales growth and the determinants of employment change during the period 1996-2002. We find that privatised and de novo firms are the main drivers of employment growth andthat, in the...

Considering Cournot competition, this note shows that, if the firms differ inlabor productivities, the equilibrium wage rates under a centralized labor union are notindependent of the number of firms and product differentiation if the labor unioncharges a uniform wage rate. However, if the...

Based on the APARCH model and two outlier detection methods, we computereliable time series of volatility asymmetry for 49 countries with relatively few ob-servations. Results show a steady increase in the asymmetry over the years for mostcountries. We nd that economic development and market...
