This paper describes an alternative approach for testing for the existence of trend among time series. The test method has been constructed using wavelet analysis which has the ability of decomposing a time series into low frequencies (trend) and high-frequency (noise) components. Under the...

type="main" <title type="main">ABSTRACT</title> <p>In this paper we propose ridge regression estimators for probit models since the commonly applied maximum likelihood (ML) method is sensitive to multicollinearity. An extensive Monte Carlo study is conducted where the performance of the ML method and the probit ridge...</p>

In ridge regression the estimation of the ridge parameter is an important issue. This paper generalizes some methods for estimating the ridge parameter for probit ridge regression (PRR) model based on the work of Kibria et al. (2011). The performance of these new estimators are judged by...

In this paper I apply the Bread and Peace model of voting in US presidential elections to analyze the sources of George W. Bush’s narrow re-election victory in 2004. The aggregate election outcome is readily explained by the model’s objectively measured political-economic fundamentals – no...

How do government-supplied institutional benefits and the taxation and regulation of producers affect the propensity of private�firms to enter the unofficial economy and evade taxation? We propose a model in which the incentive of firms to operate underground depends on tax rates relative to...

The "Partisan Theory" of macroeconomic policy is based on the idea that political parties typically weight nominal and real economic performance differently, with left-party governments being more inclined than right-party ones to pursue expansive policies designed to yield lower unemployment...

The number of House seats won by the president's party at midterm elections is well explained by three pre-determined or exogenous variables: (1) the number of House seats won by the in-party at the previous on-year election, (2) the vote margin of the in-party's candidate at the previous...
