Economic Potential of Using High Tunnel Hoop Houses to Produce Fruits and Vegetables
Full text linkAbstract Hoop house plasticulture has been promoted as a production technology that allows fruit and vegetable crops to be grown in the cool season months in early spring and late fall. At this time little information regarding the economics of hoop house plasticulture is available. Two fruit and vegetable production systems were developed for growing conditions in south-central Oklahoma. The first system has a spinach crop followed by field tomato, and the second system has annually produced strawberry followed by yellow and zucchini squash. Crop production data were collected in a three-year randomized and replicated experiment. The objectives were (1) to determine the expected cost of production for each crop and systems, (2) to determine the breakeven price for each crop in each system, and (3) to determine how robust breakeven prices are to a number of yield, expense and marketing scenarios. The expected total cost of production were 1,652 per house for spinach and tomato crops, respectively, and 359 and 3.32 and 6.16, 1.40 per pound for strawberry and yellow and zucchini squash, respectively. Breakeven prices for spinach and strawberry crops were most sensitive to assumptions about quantity of marketable yield sold and/or quantity of yield consumed by grower household.breakeven prices, economics, fruits and vegetables, hoop houses, plasticulture, Agribusiness, Farm Management, Labor and Human Capital, Marketing, Production Economics,

Measuring Vulnerability to Poverty Using Long-Term Panel Data

We use long-term panel data from Germany and apply di fferent regression models, based on household covariates and previous-year equivalence income, to classify a household as vulnerable or not. Predictive performance is assessed using the Receiver Operating Characteristics (ROC), which takes account of false positive as well as true positive rates. Estimates based on cross-sectional data are much less accurate than those based on panel data, but for Germany, the accuracy of vulnerability predictions is limited even when panel data are used. In part this low accuracy is due to low poverty incidence and high mobility in and out of poverty
The legislative agenda setting power in a changing parliamentary democracy : the Italian puzzle
No full textAccording most of the Italian and International scholars, during the so-called First Republic the short living Italian cabinets have not been enjoyed strong procedural prerogatives in the legislative process (Predieri 1964, 1975 Döring 1995). Yet, Italian politics has gone through a political and institutional upset for the last thirteen years, and also the legislative arena has been affected by changes. In this period, the Italian governments seem to have acquired a stronger role in the legislative agenda setting; parliamentary committees have lost their traditional centrality, the usual consensual style of the decision making has been often changed in a harsher one; and the legislative output has been decreased (Capano & Giuliani 2001, 2003, Zucchini 2001, Vassallo 2001, Fabbrini, 2000, De Micheli & Verzichelli 2003, Ieraci, G. 2003).
Despite this intriguing dynamics, none have tried to evaluate systematically the changes in the agenda setting power distribution, neither to connect them with other changes in the broader political environment. This paper tries to fill the existent gap.
The primary intent is to summarize the information about all current methods the government uses to control parliamentary agendas (Doering 1995, Tsebelis 2002), looking for the main changes that have taken place in the last decade. On this subject the evidence seems mixed: there are not relevant changes in the Parliamentary standing orders about the Government’s role, and no change has been carried out about the Executive’s Constitutional prerogatives. Yet, important changes have permanently taken place without the approval of new formal rules, through a the revitalisation of old constitutional prerogatives (the delegated decree authority) (Zucchini 2003), through the effects of a third player intervention (the Constitutional court), through apparently marginal innovations in the legislative process.
The secondary goal of this paper is putting forward a plausible and testable hypothesis about the source of this legislative agenda setting evolution (and its features). I argue that, at the moment, the law making is affected by two contrasting factors. On one side, the party system has turned from the pivotal to the “alternational” type (Strom 2003, Verzichelli, L. e M.Cotta 2000); therefore, Government has achieved more legislative agenda setting power vis à vis the Parliament, mainly as reaction to the increased responsiveness of Government formation and Government behaviour to electoral results. The overall effect is more delegation of legislative power from the principal-parliament to the agent–executive and from the party backbenchers to the party leadership. On the other side, the persistent high number of veto players (and the large size of the Veto players’s Pareto set) restrains the Government to play a more incisive role (Tsebelis 2002), it helps to maintain the status quo in many policy areas, it moves further the struggle for the legislative agenda setting from the Executive-legislative relationship towards the intra-Cabinet interaction. The present parliamentary debate about the reform of Italian constitution would reflect at least partially this situation
