This paper provides an opportunity for the reader to get an insight into the current modelling work atthe Research Institute for Agricultural Economics, Hungary (AKI). After giving a short summary ofthe applied econometric models in the past decade, our latest development, the farm group...

This paper aims to provide a flexible methodological framework to estimate import demandmodels, which explicitly considers the stochastic properties of data and the endogenous/exogenousnature of some variables. The French imports of virgin olive oil have been used as a case study withSpain,...

This paper aims at making the world price endogenous within the AGMEMOD modelling approach. Thisapproach constructs country-level commodity market models where supply and demand sides are equalizedon the basis of the observed domestic prices. These prices are endogenous as they depend...

A simple but new theoretical approach is used to analyse ex-ante the impact of tariff reduction. Thismethodology is based on the assumption of a constant price relation between each direct substitutableproduct. No elasticities are needed, but accurate import and domestic prices of the most...

This article tests the efficiency of the hog options market and assesses the impact of the 1996 contract redesign on efficiency. We find that the hog options market is efficient, but some options yielded excess returns during the live hogs period but not during the lean hogs period. Our findings...

The primary objective in this paper is to 'promote' the use of equilibrium displacement modelling, or comparative static analyses of general function models, as a research tool in agricultural price and policy analyses. This is by no means a new tool, but it does seem to be used much less in...

The threshold autoregressive (TAR) model by Enders and Granger (1998) and Enders and Siklos (2001) is a popular econometric model that estimates asymmetric price transmission (APT) with non-stationary time series data. However, empirical studies have not considered much the arbitrariness of...
