This paper contains an analysis of stylised natural gas and electricity supply sectors. Power plants operate either on natural gas or on a competing fuel – e.g. oil. The competing fuel is assumed to be traded at world market price whereas natural gas is sold by a national monopoly. The paper...

Standard economics rests on behavioral assumptions that are formally expressed as axioms. With the help of additional assumptions like perfect competition and equilibrium a price vector is established that displays a host of desired properties. This approach is tightly stuck in a cul-de-sac....

In the chapter below, the author presents inequalities in sector of new information and communication technologies.

From the set of the first three structural axioms follows the - economic - triangle theorem. It asserts that the product of the three key ratios, which characterize the firm, the market outcome, and the income distribution, is always equal to unity. The theorem contains only unit-free variables,...

I start from Nicola Giocoli’s acute rational reconstruction of current US antitrust debate which shows that there really is no shortage of plausible explanations to the Chicago persistent appeal puzzle. Each explanation, taken in isolation, is, at best, only partial. In my view, the persistent...

We introduce the speculation elicitation task (SET) to measure speculative tendencies of individuals. The resulting SET-score allows us to investigate the role of individual speculative behavior on experimental asset market bubbles. The experimental results show that overpricing in asset markets...

If producers have more information than consumers about goods’ attributes, then they may use non-price (rather than price) adjustment mechanisms and, consequently, the market may reach a new equilibrium even if prices remain sticky. We study a situation where producers adjust the quantity (per...
