Climate Change is one of the biggest challenges the human race is being encountered in this centaury. The continuous rise in average temperature, extreme weather occurrence, occurrence of drought and floods, intensity and frequency of storms, change in precipitation, and so many other identified...

This paper aims to highlight the trade imbalance between United States and China based on the analysis of core factors contributing the imbalance. These factors are comprise of trade inequality, exchange rate issue, difference in basic economic structure of both the countries, and methodology of...

This study explores the validation of Environmental Kuznets Curve (EKC) hypothesis for Pakistan using time series yearly data 1980-2011. We have taken deforestation as the dependant variable for environmental degradation and four independent variables i.e. income, energy consumption, trade...

In this paper, we consider the problem of estimating a semiparametric partially linear varying coefficient model. We derive the semiparametric efficiency bound for the asymptotic variance of the finite-dimensional parameter estimator. We also propose an efficient estimator for estimating the...

This paper investigates the asymptotic theory for a factor GARCH (generalized autoregressive conditional heteroskedasticity) model. Sufficient conditions for asymptotic stability and existence of moments are established. These conditions allow for volatility spillover and integrated GARCH. We...

One of the most widely-used multivariate conditional volatility models is the dynamic conditional correlation (or DCC) specification. However, the underlying stochastic process to derive DCC has not yet been established, which has made problematic the derivation of asymptotic properties of the...

While theory of autoregressive conditional heteroskedasticity (ARCH) models is well understood for strictly stationary processes, some recent interest has focused on the nonstationary case. In the classical model including a positive intercept parameter, the volatility process diverges to...

The Tobit model (censored regression model) is an important basic model appearing in many applications in economics. In this paper we consider a duration Tobit model in which a duration variable which counts the number of times the data is being censored is included as a covariate. We show that...
