We consider the problem of option hedging in a market with proportional transaction costs. Since super-replication is … very costly in such markets, we replace perfect hedging with an expected loss constraint. Asymptotic analysis for small … transactions is used to obtain a tractable model. A general expansion theory is developed using the dynamic programming approach …

also more exotic features such as combinations of single and double barriers. Price properties and hedging issues are …

We compare the performance of various hedging strategies for index collateralized debt obligation (CDO) tranches across … a variety of models and hedging methods during the recent credit crisis. Our empirical analysis shows evidence for …-dimensional bottom-up models perform better than simpler top-down models. When it comes to hedging, top-down and regression-based hedging …

The paper investigates the patterns of persistence of innovation and of the properties of firms' knowledge base (KB …

The "hierarchical and linear model of innovation" (HLMI) is often used to describe how innovations are produced. HLMI … conceiving innovation systems as associations of building blocks and using contemporary engineering diagram-based languages to … display them. Nevertheless, this improvement does not challenge the dynamic features of innovation systems …

we remain largely unaware of it. If R&D seems to be an enabler of innovation, it is not sufficient by itself. Thus, the … use the linear model of innovation as the basis for policies to promote innovation? Is it not possible to go against the …
