Economic research shows that candidates have a higher chance of getting (re-)elected when they have the luck that the world economy does well even though this is beyond their control and unrelated to their competence. Psychological research demonstrates that candidates increase their chances if...

The question of information cascades in finance appears in the literature. We use the dynamics of Kolmogorov's 1962 (K62) turbulence model, an example of multiaffine scaling, to illustrate how evidence for diffusion from large to small length scales, or correspondingly an information cascade...

Privatizing Russia offers an inside look at one of the most remarkable reforms in recent history. Having started on the back burner of Russian politics in the fall of 1991, mass privatization was completed on July 1, 1994, with two thirds of the Russian industry privately owned, a rapidly rising...

This paper reports several entirely new results on financial market dynamics and option pricing. We observe that empirical distributions of returns are much better approximated by an exponential distribution than by a Gaussian. This exponential distribution of asset prices can be used to develop...

Extending previous work on non-equilibrium option pricing theory (Eur. Phys. J. 14 (2000) 383–394), a mean field approach is developed to understand the curvature of (implied by Black–Scholes (BS)) volatility surfaces (curves) as a function of moneyness (strike price divided by price). The...

This rigorous and comprehensive textbook develops a basic small open economy model and shows how it can be extended to answer many important macroeconomic questions that arise in emerging markets and developing economies, particularly those regarding monetary, fiscal, and exchange rate issues....

Interest in thermodynamic analogies in economics is older than the idea of von Neumann to look for market entropy in liquidity, advice that was not taken in any thermodynamic analogy presented so far in the literature. In this paper, we go further and use a standard strategy from trading theory...

In their path-finding 1973 paper, Black and Scholes presented two separate derivations of their famous option pricing partial differential equation. The second derivation was from the standpoint that was Black's original motivation, namely, the capital asset pricing model (CAPM). We show here,...
