"Standard" environmental economics considers emissions trading to be the most effective and efficient policy instrument to meet the emission target. However, a popular view is that tradeable permits should be part of a policy portfolio, including other instruments, to reach this goal. Support...

XVA models for the calculation of CVA, FVA (see for example (Burgard and Kjaer 2013)), KVA(Green, Kenyon, and Dennis 2014), MVA (Green and Kenyon 2014) and TVA (Kenyon and Green 2014a) have frequently been formulated at the counterparty level. However, it is clear that some elements of the...

This paper considers the effects of imperfectly communicated information about whether a regulator initiates a bailout program for financially distressed banks. The theoretical framework allows for determining whether, and to what extent, it is optimal for a regulator to be imprecise in...

We develop a macroeconomic framework in which firms are large and have market power with respect to both products and labor. Each firm maximizes a share-weighted average of shareholder utilities, which makes the equilibrium independent of price normalization. In a one-sector economy, if returns...

This paper develops a theory of patent portfolios in which firms accumulate an enormous amount of related patents in diverse technology fields such that it becomes impractical to develop a new product that with certainty does not inadvertently infringe on other firms' patent portfolios. We...

We consider competition among n sellers when each of them sells a portfolio of distinct products to a buyer having limited slots (or shelf space). We study how bundling affects competition for slots. When the buyer has k number of slots, efficiency requires the slots to be allocated to the best...

Consumers often purchase more than one differentiated product, assembling a portfolio, which might potentially affect substitution patterns of demand and, as a consequence, oligopolistic firms' pricing strategies. To study such consumers' portfolio considerations, this paper develops and...

In many industrial sectors, firms amass large patents portfolios to reinforce their bargaining position vis a vis competitors. In a context where patents have a pure strategic nature, we discuss how the presence and the effectiveness of a patent system affect firms technological decisions....
