This article is about estimation and inference methods for high dimensional sparse (HDS) regression models in econometrics. High dimensional sparse models arise in situations where many regressors (or series terms) are available and the regression function is wellapproximated by a parsimonious, yet unknown set of regressors. The latter condition makes it possible to estimate the entire regressi...

The objective of this article is to investigate why farmers in Kosovo leave land fallow when the total land of their farms is small and households, almost fully dependent on farming for their livelihoods, are large. In order to elicit some of the barriers to land utilization, the article uses a comprehensive survey carried out during the agricultural year 2005/2006 to explore agricultural house...

Section II presents the empirical results of this study. While the underlying econometric model follows the standard ‘new growth’ literature procedure of regression analysis in a cross-section of countries, it goes beyond the existing studies in drawing on a data set including proxies for technical progress and educational attainment as well as devoting special attention to different levels of ...

This paper presents an econometric model that combines macroeconomic time series data with historical series relating to political instability in Israel during the Intifada period, in order to provide a conservative estimate of the extent to which variations in economic performance over time have a political explanation. Political instability is found to have a substantial effect on the cyclica...

The primary purpose of this paper is to construct and estimate an econometric model for the Jonsei-to-Purchase price ratio (JPR), and to draw implications for the development in the Korean housing market. In particular, we are interested in: a) identifying regimes across which the ratio shows markedly different dynamic behavior; and b) drawing implications from the model for the recent increase...

The few existing empirical studies of U.S.-Japan trade agreements have relied primarily on descriptive statistics or univariate time series methods. We conduct a more powerful test by evaluating agreements in the context of well-specified econometric models. Consistent with trade theory, import demand is modeled as a cointegrating relationship with income and relative price variables, where a t...

This paper allows for the effect of taxation in the econometric model for the analysis of exploration and production policies of "price taking suppliers" recently proposed in Pesaran( 1990). The tax system in the UKCS is neither neutral nor stable, therefore the separation of the "deep" parameters in the model from the tax parameters is an issue of crucial importance. The inclusion of taxation ...

where wt+n = [xt+1, x ′ t+2, . . . , x ′ t+n] ′ for a positive integers n. The conditional expectation is taken with respect to the distribution of the vector ηt+n =[εt+1, ε ′ t+2, . . . , ε ′ t+n] ′, given wt+n is generated by the recursion (A.1). β ∈ B is a vector of parameters. In our application, f is the vector of nominal discount bond prices, g is the vector of corresponding pricing kerne...

JEL codes: L51, L96 I examine the effects of FCC regulation on the innovation and introduction of advanced telecommunications services in the U.S. An interim of lighter regulation provides an “experiment” to test the regulatory regime’s impact on innovation. The econometric model comprises an arrival process (for service innovation) followed by a duration process (for regulatory delay). The num...
