World trade has grown rapidly. Several factors are highlighted by literature as a driving force behind the growth of world trade. Reduction in barriers to trade is one of them. A comprehensive empirical investigation is carried to ascertain the trade reducing and increasing effect of barriers to...

The paper introduces for the most frequently used three-dimensional fixed effects panel data models the appropriate Within estimators. It analyzes the behaviour of these estimators in the case of no-self-flow data, unbalanced data and dynamic autoregressive models.

The paper introduces for the most frequently used three-dimensional panel data sets several random effects model specifications. It derives appropriate estimation methods for the balanced and unbalanced cases. An application is also presented where the bilateral trade of 20 EU countries is...

In theoretical literature on productivity, the disturbance terms of the stochastic frontier model are assumed to be independent random variables. In this paper, we consider a stochastic production frontier model with residuals that are both spatially and time-wise correlated. We introduce...

This paper addresses the issue of threshold effects between public debt and economic growth in the Caribbean. The main finding is that there exists a threshold debt to gross domestic product (GDP) ratio of 55–56 percent. Moreover, the debt dynamics begin changing well before this threshold is...

This paper investigates 53 public HEIs in Turkey between 2005 and 2010 including 5 full academic terms to estimate both their cost frontier and inefficiencies. The initial findings of six different models imply that Turkish universities perform quite well concerning their overall efficiency...

Literature on the relationship between aid and inequality is scarce and contradictory. Most studies are based on dynamic panel data using internal instruments to deal with endogeneity. In addition to these techniques, this article introduces the persistency of inequality and a double-censored...

In the course of a comprehensive labor market reform started in 2002 and finished through the implementation of the most radical measure Hartz IV in 2005, I exploit its impact on matching processes in Germany. I use disaggregated data for 178 local employment agencies to examine the effects of...

This paper studies the sequential sampling scheme as a solution to the problem of aliasing, where the sampling interval is restricted to a minimum allowable value. Sequential sampling is analyzed and it is proved that when the sampling ratio is an integral number, the associated spectral...

A gravity-based model is developed to explain bilateral trade flows in primary and processed agri-food commodities. It innovates by explicitly accounting for the vertical production linkages between primary and processed agri-food products, tariffs, and subsidies and by estimating the...
