We find favorable evidence for the textbook equilibrium exchange rate model of Stockman (1987) using Blanchard and Quah’s (1989) decomposition. Real shocks are shown to account for more than 90 percent of movements in the real exchange rate between Brazil and the US, and for more than half of...

This paper provides estimates of the elasticities of demand for the Brazilian basic plan of local fixed telephony using a cointegration model. We find a long-run price elasticity of –0.24, and an income elasticity of 0.18. These figures are line with other countries’ estimates.

The yuan-dollar returns prior to the 2005 revaluation show a Sierpinski triangle in an iterated function system clumpiness test. Yet the fractal vanishes after the revaluation. The Sierpinski commonly emerges in the chaos game, where randomness coexists with deterministic rules [2, 3]. Here it...

Investors seem to hold on to their losing stocks to a greater extent than they hold on to their winning stocks. This well-document behavioral regularity is termed disposition effect (Shefrin and Statman 1985). We set an experiment to replicate results from a previous study of the disposition...

Because sports are stylized combat, sports may follow power laws similar to those found for wars, individual clashes, and acts of terrorism. We show this fact for football (soccer) by adjusting power laws that show a close relationship between rank and points won by the clubs participating in...

Regional income dispersion is a sensitive issue in China in terms of judging the impact of economic reform. This study looks closely at the issue as to what are the determinants of income variation among households in general, and which are the key determinants of income dispersion among...

In a simple form, the basic relationship that can be used while exponential neat, is given by the expression: (for t ≥ 2) Where: St = the adjusted values of the dynamic series; yt = the levels of the empiric series; St-1 = the adjusted value of the term t – 1; w = a constant of adjustment...

This paper studies repeated games where the time of repetitions of the stage game is not known or controlled by the players. Many economic situations of interest where players repeatedly interact share this feature, players do not know exactly when is the next time they will be called to play...

This paper summarizes the theory of knowledge from the book of the same title by the same author. The paper begins by asking, and answering, what knowledge is. In searching for precise definitions it rids itself of the ambiguous term of infinity. The seven main laws of knowledge are laid out and...

We analyze an economy populated by a sequence of generations who decide over their consumption levels and the levels of investment in human capital of their immediate descendants. The objective of the paper is to identify the impact of strategic interactions between consecutive generations on...
