This paper uses data from a survey of two hundred and fifty cattle keeping households in three cattle keeping systems; intensive, semi-intensive and extensive systems to estimate the value of non-market, socio- economic benefits of cattle in Kenya. These benefits of cattle keeping are of special importance in developing countries, where financial markets function poorly and opportunities for risk management through formal insurance generally absent. However, when estimating the total contribution of livestock, these non - market functions are often ignored since they are difficult to value, yet they may contribute to a better understanding of livestock production systems. The use of contingent valuation method is employed in this study to elicit these non-market values. Econometric estimations are then used to assess the factors influencing the non - market benefits function. The results indicate that these benefits are highly valued by cattle keepers and comprise approximately 20% of the animal.s total value across the three systems. They are influenced by various production system and household related factors. Implications for policy are drawn.

Voluntary environmental agreements have been popular with government agencies in several countries. However, many questions remain about their efficiency as a regulatory tool. Recent analyses suggest that they are more effective than conventional regulatory or economic approaches when dealing with diffuse pollution and when innovation processes at the source are necessary to define effective regulation. This paper applies an activity-based framework to assess the contribution of such a voluntary agreement to the environmental performance of farms participating in a whole farm plan in the Southern part of Belgium. Using a cross-section of 52 farms, our results show that farms entering into environmental agreements are environmentally more efficient than non-participating farms in terms of the preservation and provision of landscape features. However, their environmental efficiency with regard to the reduction of non-desirable outputs, such as organic nitrogen, is mostly determined by technical efficiency and not by participation in the whole farm plan.

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.
