The capability to present electronic media that can preserve information is highly restricted to few decades (e.g., a lifetime of DVD media does not exceed 100 years), and therefore the question of how to preserve documents for more than thousands or millions of years presents a challenging...

The traditional marshallian rule of investing when the value of the investment is greater than its installment cost is modified in the presence of irreversibility and uncertainty, giving rise to an option component. Additionally, the interaction of participants holding each one a right to invest...

What information about the financial condition of firms is conducive to efficient and stable operation of the financial system and of the economy more broadly? In this essay, we outline the contours of an ideal set of such information, identify existing gaps and propose a way forward to fill...

Implied volatility generated from observed option prices reflects market expectations of future volatility. This paper determines whether or not, implied volatilities, and hence market expectations, contain any genuinely forward looking information not already captured by historical information....

The Efficient Markets Hypothesis (EMH) has been one of the most influential ideas in the past years and highlights that assets prices incorporate all information rationally and instantaneously. The last financial crisis has led to criticism of this hypothesis. Many practical observations...

The paper proposes a critical analysis, based on consistency criteria, regarding the controversed current state of the informational efficiency theory of the capital market (Efficient Market Hypothesis). Nowadays, after several decades of research and thousands of studies, economists have not...

The traditional marshallian rule of investing when the value of the investment is greater than its installment cost is modified in the presence of irreversibility and uncertainty, giving rise to an option component. Additionally, the interaction of participants holding each one a right to invest...

We study communication in a static Cournot duopoly model under the assumption that the firms have unverifiable private information about their costs. We show that cheap talk between the firms cannot transmit any information. However, if the firms can communicate through a third party,...

Rational voters update their subjective beliefs about candidates' attributes with the arrival of information, and subsequently base their votes on these beliefs. Information accrual is, however, endogenous to voters' types and difficult to identify in observational studies. In a large scale...
