This paper compares three valuation models – discounted dividends, discounted cash flow, and residual earnings – using financial and accounting data from Brazilian companies, during the period of 1995 to 2004. These approaches should be theoretically equivalent when the respective companies'...

We adapt a genetic-based learning classifier system to a forecast evaluation exercise by making its key parameters endogenous and taking into account the need of convergence of the learning algorithm, an issue usually neglected in the literature. Doing so, we find it hard for the algorithm to...

The number of downloads of economics articles through the repository RePEc showed a sharp drop on the eve of the Great Recession in the economy. This unambiguously occurred with the Blue Ribbon journals, but can possibly be extended to other important journals. If we can perhaps talk of a great...

Overconfidence can lead to excessive business entry. Here we replicate the pioneer experiment finding this nexus (Camerer and Lovallo 1999) and extend it in two major directions: (1) to consider managers as well as student subjects and (2) to explicitly take into account selected characteristics...

The relative efficiency of financial markets can be evaluated using algorithmic complexity theory. Using this approach we detect decreases in efficiency rates of the major stocks listed on the Sao Paulo Stock Exchange in the aftermath of the 2008 financial crisis.

We revisit the issue of comovements of emerging and developed stockmarkets, and provide a simultaneous treatment of data for the eighties and nineties. We show that while emerging markets experience greater instability in the long term than their developed counterparts, there is room for...

Price changes of the Chinese yuan/US dollar rate are found to display a Sierpinski triangle in an Iterative Function System clumpiness test. This fractal structure commonly emerges in “the chaos game”, where randomness coexists with deterministic rules. We show that a threshold model with...

We detected bubbles in 22 emerging stockmarkets using both standard and threshold cointegration. Eighteen stockmarkets experienced explosive bubbles (and some of them periodically collapsing bubbles as well). The remaining four markets experienced periodically collapsing bubbles only.

We find evidence of weak informational efficiency in the Brazilian daily foreign exchange market using Hurst exponents (Hurst 1951, 1955, Feder 1988), which offer an alternative (from statistical physics) to traditional econometric gauges. We show that a trend toward efficiency has been reverted...

The strong Brazilian currency between 1994 and 1998 led Brazilians to an unprecedented increase in their travels abroad. Even after the 1999 currency crisis, travel patterns did not recover to their pre-exchange rate devaluation levels. The occasional exchange rate valuation has left...
