In this paper we consider a compound Poisson risk model where the insurer earns credit interest at a constant rate if the surplus is positive and pays out debit interest at another constant rate if the surplus is negative. Absolute ruin occurs at the moment when the surplus first drops below a critical value (a negative constant). We study the asymptotic properties of the absolute ruin probabil...

The agricultural sector is of particular importance in the city of Bijar. Thus, the economic value perunit of water applid to the side effects of excessive groundwater resources in this area has a utmostimportance. Payment for estimation of water on a suitable production function was estimated revenueproducers. Therefore in this study to estimate the economic value of water resources in agricul...

This paper justifies and specifies testable hypotheses about the relationship between the individual wage and the average level of subsistence productivity in the Jamaican labour market, as well as the degree of competitiveness. First, a framework is derived as a mathematical-economic model that links the marginal product of labour to the scale of unemployment or subsistence employment through ...

This paper describes the questions on the consequences of the assumptions about resource sustainability and economic growth and whether sustainability and economic growth foreclose each other. Specifically, it examines four questions by: (1) Identifying the main factors in earth resource consumption in the past 40 years; (2) Finding relationships among person’s nutrition demands, food Ecologica...

We present a model of N-player contracting with transaction costs and endogenous property rights. Ex ante agreed surplus sharing can be altered ex post, after irreversible investments in production (characterised by the generalised Cobb-Douglas production function). The actual surplus sharing is determined ex post, after each player has chosen a costly action to alter the surplus sharing in his...

The literature on treatment effects focuses on gross benefits from program participation. We extend this literature by developing conditions under which it is possible to identify parameters measuring the cost and net surplus from program participation. Using the generalized Roy model, we nonparametrically identify the cost, benefit, and net surplus of selection into treatment without requiring...
