It is well known that the analysis of efficient specialization in Ricardian production with many countries and many commodities cannot be broken down to the simple case of two countries and two commodities. By drawing on some recent results of convex geometry and the theory of cephoids, this...

The basis for the empirical research on earnings determination is the Mincer equation. Individuals are assumed to make schooling decisions by maximizing earnings. Leisure costs of schooling and labour supply are neglected which has some empirically implausible implications. This paper shows a...

Assuming decreasing returns to education and the endogenous supply of qualified and non-qualified labour it is shown to be efficient to supplement a consumption tax with positive incentives for education. If the return from education is isoelastic and if the choice is between (i) subsidizing the...

The OECD seeks to align transfer pricing and profit taxation with value creation but fails to provide a clear definition. This paper argues that value creation requires international cooperation and that the profit tax base should therefore be allocated according to standards commonly considered...

The use of digital services is largely non-rival. This paper argues that vanishing marginal costs of supply change policy incentives. Small countries are incentivized to tax the import of digital services. In fact, various countries have already moved towards expanded source taxation of online...

The research on earnings determination is based on the Mincer-Becker assumption that individuals decide on schooling by maximizing income. This paper offers an alternative and less restrictive approach based on utility maximization. Using this approach, we analyze the efficiency of education...

The adequate pricing of intellectual property ("IP") for tax reporting is a largely unsettled issue. Transactional profit-based methods are on the rise although only rated as "methods of last resort" by the OECD. This paper focuses on regulated profit splitting and compares this transfer pricing...

The planning practice of health care capacities suffers from sectoral and regional constraints and it remains difficult to ensure an equal access for patients. Moreover, standard planning approaches lack the choice-theoretic grounding necessary for making reliable predictions of the demand and...
