A standard test for weak instruments compares the first-stage F-statistic to a table of critical values obtained by Stock and Yogo (2005) using simulations. We derive a closed-form solution for the expectation from which these critical values are derived, as well as present some second-order...

The general objective of the study is to quantify the economic potential of 98 municipalities in the province of Seville in 2007 and 2012 from empirical research based on the application of the Rasch model.

At emerging financial markets, the R&D, intangible and technological basis firms (TBF) valuation, they make the traditional real option binomial approach questionable. For that, a numerical model that modified the traditional binomial model is proposed, incorporating trinomial lattice, changing...

This paper proposes an approach to measure the extent of nonlinearity of the exposure of a financial asset to a given risk factor. The proposed measure exploits the decomposition of a conditional expectation into its linear and nonlinear components. We illustrate the method with the measurement...

For nearly every major stock market there exist equity and implied volatility indices. These play important roles within finance: be it as a benchmark, a measure of general uncertainty or a way of investing or hedging. It is well known in the academic literature that correlations and higher...

Recently, several copula-based approaches have been proposed for modeling stationary multivariate time series. All of them are based on vine copulas, and they differ in the choice of the regular vine structure. In this article, we consider a copula autoregressive (COPAR) approach to model the...

In this article, we carry out a study about one of the most disruptive topics in recent times: cryptocurrencies. Whether as a revolution in payment methods, because it is a speculative asset or because of the particularities of the technology on which it is supported, cryptocurrencies are...

The present study has been conducted to examine the impact of seven of most important internal factors on stock prices for all listed banks in Dubai and Abu Dhabi stock markets. Pooled Least Square, Fixed Effects (FE), and Random Effects (RE) models have been used to carry out the analysis for...
