Most skills acquired through on-the-job training may be specific to an occupation and therefore transferable to some but not all firms. However, economists have typically focused on skills that are either specific to a given firm or skills that are completely general. This paper explores the relationship between the size of the local market for an occupation-specific skill and job-training outc...

In this paper we consider the possible dependence of the market price of risk on time and interest rates. This fact gives as a result that the risk-neutral drift, which is one of the coefficients of the pricing equation, also depends on time and interest rates. Then, we estimate the risk-neutral drift directly from the slope of the yield curve. This approach is very accurate as we show with a n...

This paper proves that the Black-Scholes model is not vulnerable to its assumption on the underlying process, because the same fundamental PDE can be derived by the possibility of continuously rebalancing a delta-gamma-neutral position, without assuming anything about the underlying process. Since the variance function of the PDE should be interpreted as the market price of convexity, it is not...

This article investigates use of the Principle of Maximum Entropy for approximation of the risk-neutral probability density on the price of a financial asset as inferred from market prices on associated options. The usual strict convexity assumption on the market-price to strike-price function is relaxed, provided one is willing to accept a partially supported risk-neutral density. This provide...

A thin market is a market with few buying or selling offers. The concept of market thinness, while general, is typically used in the context of financial markets. When the number of buying or selling offers is small, investors' trading positions are large relative to market size. Trading then requires price concessions and thus exerts an impact on prices. A thin market is characterized by low t...

This paper studies the inventive performance and profitability of small and medium sized firms (SMEs) that are “technology specialists” compared to the inventive performance and profitability of SMEs that are instead vertically-integrated. In this paper perspective, “technology specialists” are firms that specialize upstream in generating inventions and trade those inventions in disembodied for...

The transition from conventional power sources to renewable energy sources is taking place in a number of European countries. Electric energy storage has been proposed as an environmentally friendly solution to make this transition possible. This thesis analyzes the profitability of investing in a battery bank in Germany and the UK, using a real options model. The model determines the option va...

The paper investigates issues of scale equivalence and generalisability across different populations. This area of research is important because it allows for valid comparisons to be made when studies investigate the same constructs across qualitatively distinct populations. The study investigates the generalisability of the Narver and Slater (1990) and the Kholi, Jaworski and Kumar (1993) mode...
