| This paper examines the changes in nutritional behavior of Russian adults over the ten-year transition period, between 1994 and 2004. We present evidence on the impact of individual as well as regional characteristics on changes in fat, protein, alcohol and cigarette consumption, and on diversity of diet. The results from a dynamic empirical model suggest that among microeconomic determinants, initial levels of consumption, gender, holding a university degree, and having access to a garden plot have a significant impact on the changes in consumption behavior in Russia. Regarding the macroeconomic variables, economic growth has a significant impact on changes in fat and protein consumption and on alcohol use, while unemployment changes significantly... |

| Russian dairy enterprises underwent dramatic changes during 1990-2001. Not much is known about the position of these enterprises under the new conditions. This study examined a sample group of dairy enterprises in the Moscow region to try to identify similarities and divergences in historical background, performance, managerial and structural characteristics. A unique farm-level data set from 1990-2001 was used. Assessment of historical characteristics revealed that the currently most successful enterprises were those which in pre-reform years had already shown better economic performance. These farms also had, for the period studied, smaller percentages of reduced resources, no severe debt problems, and better overall management. |

| This study develops a micro econometric model of specialised dairy farms in Moscow Region using panel data over the period 1995-1998. The model is used to analyse the role of input and output subsidies in the on-farm decision making. Theoretical conditions for short term profit maximization and the fixed effect specification are not rejected by the data. Estimates of the parameters related to input and output subsidies are found to be highly significant. The effect of output subsidies on milk output supply is larger then the price effect. Output subsidies are allocated efficiently in the period 1996-1998 and inefficiently in 1995; input subsidies are allocated efficiently in 1995 and inefficiently in 1996-1998. |

| This paper outlines DEBET (Decision Based Economic Theory), a method for determining revealed preferences of governments. DEBET is applied to US wheat policy decisions in the 1980s. This method has a number of advantages over alternative approaches to the analysis of revealed preferences of government. It makes use of information contained in policy alternatives contemplated but not agreed upon, and it is suitable for modeling the discrete - continuous choice problem of policy makers in a multi-instrument context. |

| Decision based economic theory stresses the central position of the objective function in the behavior of economic agents. Insufficient knowledge of objective functions hampers the development of economic theory. In this article, a methodology for deriving objective functions from conscious decisions has been developed. Three categories of decisions are concerned: positive, negative, and mutually exclusive decisions. Assuming minimal inconsistency, the objective function can be derived by means of linear or nonlinear programming and using a revealed preference approach. The method has been applied to derive the linear objective function of EC dairy policy. However, applications of this methodology for consumers and producers are similar. A number of... |

| There is some confusion in the literature on the consumption behaviour of farmers. We try to clear up some of the issues surrounding this confusion by elaborating and testing a model. Euler equations have been derived from a constant relative risk aversion utility function for total consumption expenditure, household expenditure and other expenditure, which includes durable goods. According to a test of Euler equations, farm households are not simply optimising lifetime utility. Rather, these households follow simple consumption rules, strongly influenced by habit formation. In line with most of the literature, we find that farm households are not borrowing constrained in their consumption expenditures. |

| Investment models typically explain only a small share of the total investment variation within or between firms. A reason for this may be that those models do not explicitly differentiate between the decision to invest and the decision about the level of investment. In this paper, a two-steps theoretical framework and estimation procedure are developed to take into account the different nature of both decisions. ‘Nearly zero’ investments are considered to be small replacement or maintenance investments and treated as ‘zero’ investments. The applied two-step Heckman model shows that the decision to invest is significantly related to available capital (-), wealth (+), debts (-), output prices (+), land price growth (+), capital price growth (-), energy... |

| The entry and exit decisions, considered as investment decisions, are investigated in the paper. Taking into account the heterogeneity of entry and exit, the analysis is based on two types of entry-exit: real (related to the establishment or closing of a firm), or entry-exit in a new sector (indicating the diversification or changing specialisation). The theoretical model is based on Marshallian trigger points with Real Option trigger points as an alternative. The estimation exploited the negative binomial model to investigate the role of trigger points (thresholds) on the observed number of entry or exit firms in Dutch glasshouse horticulture over 25 years. Firms should overcome different thresholds depending on types of entry and exit. Marshallian... |
