In this study we examine in covariance stationary time series the consequences of constructing confidence intervals for the population mean using the classical methodology based on the hypothesis of independence. As criteria we use the actual probability the confidence interval of the classical...

Twelve econometric studies investigating the impact of agoa presented in this paper have reported 174 different estimates. In testing for publication bias and whether there is a genuine empirical impact of agoa we resort to a meta-analysis. The meta-analysis provides us with a formal means of...

The present work corroborates the existence of two anomalies that question the hypothesis of efficient markets in the Chilean stock market, these are the “effect weekend” or “effect monday” and the “effect month end”. Using the daily values of closing of stock-exchange index IPSA,...

(Re)insurance companies need to model their liabilities' portfolio to compute the risk-adjusted capital (RAC) needed to support their business. The RAC depends on both the distribution and the dependence functions that are applied among the risks in a portfolio. We investigate the impact of...

Despite the governments took rescue and/or stimulus packages, signs of recovery occurring in 2009 and 2010, the global growth sustainability seems uncertain. Romania was hit hard by the crisis, suffering a severe contraction of the economy, estimated at 7.1 percent in 2009. The worsening of the...

Ever since the pioneering work of Cox, Ross and Rubinstein, tree models have been popular among asset pricing methods. On the other hand, statistical estimation of parameters of tree models has not been studied as much. In this paper, we use K Means Clustering method to estimate the parameters...

The contribution of this paper to the literature is three-fold: (1) it empirically uncovers the directionality and persistence of systemic risk surrounding "the great recession"; (2) it quantifies the reaction of the macro-economy to financial (banking) system shocks; and (3) it unearths...

Based on a deterministic hypothesis, this paper aims to verify the regularity of the stock market cycles and, if this regularity is found, the ability to predict major stock market crises. Harmonic analysis, or Fourier series, is applied in order to, decomposing into sinusoids curves, find the...

In this study, using Monte Carlo simulations, we evaluate three alternative methods for constructing confidence intervals for the population mean in the case of a stationary first order autoregressive process, AR(1), with parameter ф. Differentiating the three methodologies with respect to the...

On many occasions we need to construct an index that represents a number of variables. Cost of living index, general price index, human development index, index of level of development, etc are some of the examples that are constructed by a weighted (linear) aggregation of a host of variables....
