We develop an ordinary least squares estimator of the long memory parameter from a fractionally integrated process that is an alternative to the Geweke Porter-Hudak estimator. Using the wavelet transform from a fractionally integrated process, we establish a log-linear relationship between the...

Econometric techniques to estimate output supply systems, factor demand systems and consumer demand systems have often required estimating a nonlinear system of equations that have an additive error structure when written in reduced form. To calculate the ML estimate's covariance matrix of this...

This paper introduces several new Bayesian nonparametric models suitable for capturing the unknown conditional distribution of realized covariance (RCOV) matrices. Existing dynamic Wishart models are extended to countably infinite mixture models of Wishart and inverse-Wishart distributions. In...

This paper proposes a flexible way of modeling dynamic heterogeneous covariance breakdowns in multivariate GARCH (MGARCH) models. During periods of normal market activity, volatility dynamics are governed by an MGARCH specification. A covariance breakdown is any significant temporary deviation...

The time-series dynamics of short-term interest rates are important as they are a key input into pricing models of the term structure of interest rates. In this paper we extend popular discrete time short-rate models to include Markov switching of infinite dimension. This is a Bayesian...

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...
