This paper examines the stationarity of carbon dioxide (CO2) emissions per capita for a set of 36 countries covering the period 1870–2006. We employ recently developed unit root and stationarity tests that allow for the mean reverting process to be nonlinear and take into account cross...

In this paper we analyze the relationship between income and health expenditure in 31 Organization for Economic Cooperation and Development (OECD) countries. We focus on the differences between short and long term elasticities and we also check the adjustment process of health care expenditure...

To analyze policy impacts of a targeted employment program calls for a new approach of estimation. This study proposes a simple modification to a Social Accounting Matrix (SAM) in order to analyze the multiplier effects of a new sector. A different input composition, or technology, of the sector...

This paper evaluates the household food security situation in Kenya in terms of access to food. We apply a quadratic almost ideal demand system (QUAIDS) model to nationally representative household survey data from Kenya, and estimate and interpret price and expenditure elasticities as...

This paper finds that factors such as caste and religion influence food security at the regional level. Thus defining affirmative action within food security programs may be necessary as the current practice of designing food security programs around the poverty line is shown to deliver limited...

In this paper we generalize the median regression method to be applicable to system of regression equations, in particular SURE models. Giving the existence of proper system wise medians of the residuals from different equations, we apply the weighted median regression with the weights obtained...

This paper analyses a second-order polynomial spatial structure in the residues of a regression model. We propose a new specification that captures spatial dependence on two different levels, adding a new autoregressive cycle to the errors of the classical spatial error model (SEM). The...

The article analyzes the population shares of employed, unemployed and other men and women by utilizing the 2001 Greek Census data collected at the municipal level. It departs from other studies on the subject by (a) considering not one but all economic activities simultaneously, (b) trying to...

The aim of this paper is to put forward a beta convergence model using spatial interaction to evaluate the dynamics of financial ratios. We overcome some of the limitations that come from the traditional partial adjustment model by relating both models. We show that the parameters of the two...

The objective of this paper is to analyse the hospitalisation and the pharmaceutical expenditures of a population. To do so, we will use cross-sectional information for the year 2004, referring to the whole population of one of the seventeen autonomous communities that make up the Spanish public...
