Drawing on the views of three selected Czech philosophers – Rádl, Fischer and Rieger – on questions of physics and their possible philosophical reflection, the author conjectures how these thinkers, consistent with their original views, might respond to currently discussed contemporary questions. Specifically, at the time of the conference, it was the then current problem of neutrinos and of their speed, which apparently had been measured at more than the speed of light. At issue are primarily methodological postures, views concerning the proper range of philosophy on the basis of which we can, given appropriate speculation, derive a highly probable stance which the selected philosophers represented and, more generally, their probable approach to contemporary issues.
In financial markets, speculation is justified by its contribution to liquidity, hedging, and, if rationally done, adjusting price to value. Derivatives are essential for turning speculation into an element that contributes to an efficient market. Property assets have the distinctive feature of being both residential and productive assets and investment assets. This paper studies how speculation may contribute positively to the real estate market and does so by looking at it from the triple perspective of property, primitive financial assets, and derivatives. To answer this, the authors try to identify which assets are needed to achieve this end and how they can help to guide speculation towards efficiency. On this basis, we examine the development of derivatives on real estate indexes and the perspectives of their future evolution, including their impact on the real market.
