Stepwise model selection criteria were tested against the restrictive forms to determine the appropriate model and to confirm the law of one price for the US soybeans. Analysis shows less than one international price transmission and exchange rate elasticities in the long run indicate an...

This paper examines regional differences in obesity rates, Body Mass Index (BMI) and dietary quality, using data from the 1999-2002 National Health and Nutrition Examination Survey (NHANES), Mobile Examination Center (MEC). For women, BMI and obesity prevalence may be higher in the Deep South...

Tobacco production in China is influenced by a government-set procurement price for tobacco leaf, and an excise tax on tobacco leaf revenue. This study examines the increase in the procurement price needed to keep tax revenue constant in the face of a 50% reduction in the tax rate. This...

In den letzten Jahren hat sich die Bioenergieproduktion rasant entwickelt, so dass man mittlerweil von einem "Bioenergieboom" sprechen kann (WBGU 2008:1). Maßgeblich unterstützt wurde dieser Trend hierzulande durch die starke politische Förderung von Bioenergie sowohl von Seiten der...

The threshold vector error correction model is a popular tool for the analysis of spatial price transmission and market integration. In the literature, the profile likelihood estimator is the preferred choice for estimating this model. Yet, in certain settings this estimator performs poorly. In...

Estimation of threshold parameters in (generalized) threshold regression models is typically performed by maximizing the corresponding profile likelihood function. Also, certain Bayesian techniques based on non-informative priors are developed and widely used. This article draws attention to...

Agricultural commercialization has become the centerpiece of the sector development strategy in Uganda in recent years. Nevertheless the low market participation of most smallholders in the country remains a fact. We employ semi-parametric regression techniques to analyze the current state of...

Maize is a major staple food in Sub-Saharan Africa. Monthly maize prices in Tanzania are analyzed since the country is an important maize producer and exporter in East Africa. We analyze price transmission between the five most important urban regions of Tanzania between 2000 and 2008 which...

This study aims to improve our understanding of the extent and speed of the transmission of international cereal prices to local markets in developing countries. We analyse two samples of price transmission (PT) estimates, one extracted from a comprehensive literature sample of 31 published...

Economists use partial and general equilibrium trade simulation models toestimate the impact of changes in domestic policies and international trade rules.During the WTO Doha Development Agenda (DDA) negotiations economists haveproduced many different estimates of the gains that would result...
