This paper presents a comprehensive economic analysis of recycling organic wastes through composting. A mathematical programming model is developed to examine the optimal level of compost production from sources of organic municipal solid waste, livestock manure and wastewater-treatment sludge....

Knowledge spillover implies that the social value of knowledge is higher than its private value and leads to insufficient private investment in human capital. This paper examines implications for economic growth and offers a remedy. An incentive mechanism that implements the socially optimal...

The dynamics of biomass growth implies that the yield of irrigated crops depends, in addition to the total amount of water applied, on irrigation scheduling during the growing period. Advanced irrigation technologies relax constraints on irrigation rates and timing, allowing to better adjust...

The income inequality implications of land reform are examined for the case of Georgia using regression-based inequality decomposition techniques. An egalitarian land redistribution is likely to equalize per-capita income among farm households, implying that continuing the land reform process in...

This article proposes a nonparametric analysis in which the change in the distribution of farm size between two periods is decomposed into several components, and the contributions of subgroups of farms to this change are analyzed. Using data on Israeli family farms, we analyze the changes in...

We use a mixture regression model to identify segmentation in the Israeli labor market, and propose a new method for assigning workers to simulated segments. We identified a lowwage segment and a high-wage segment, as well as a third segment with a large wage variability that we interpret as...

People often need to choose between alternatives with known probabilities (risk) and alternatives with unknown probabilities (ambiguity). Such decisions are characterized by attitudes towards ambiguity, which are distinct from risk attitudes. Studies of ambiguity attitudes have thus far focused...

This comment critically discusses the theoretical and empirical treatment of corner solutions in the analysis of labor decisions on farm households. As more and more labor decisions are analyzed jointly, the more ambitious becomes the theoretical justification of empirical applications. "Cutting...
