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...

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...

Intrinsically trustworthy agents never cheat. A society's willingness to trust and the quality of its institutions have their origins in the intrinsic trustworthiness of its citizens. Trustworthiness is the basis for maximizing output in economic exchange and in explaining differences in...

The instrumental variables strategy is commonly employed in empirical research. For correct inference using this econometric technique, the instruments must be perfectly exogenous and relevant. In fact, the standard t-ratio test statistic used in this context yields unreliable and often...

This paper introduces endogenous capital income tax rates as in Schmitt-Grohe and Uribe (1997), into the overlapping generations model with endogenous labor and consumption in both periods of life (e.g., Cazzavillan and Pintus, 2004). In contrast with the previous result that the existence of...

Israel’s policies regarding Lebanon have been dependent on public opinion, which is very volatile. The citizens of Israel did not favor the occupation of the security zone in South Lebanon because of the Four Mothers movement, and it influenced the government to withdraw military forces...

This research attempts a theoretical and quantitative analysis of authoritarian regimes enduring in the developing countries. We attempt computer visualization of the model developed by Acemoglu and Robinson in order to derive an empirical hypothesis easily. There is a reason for us to accept...
