Some economic effects of the California agricultural labor relations act

The California Agricultural Labor Relations Act (CALRA) evolved in the 1970s because the National Labor Relations Act (NLRA) excluded agricultural workers. CALRA effectively placed the United Farm Workers Union in a stronger bargaining position vis-a-vis farmers than the NLRA had done for industrial unions vis-a-vis nonfarm business firms. Society has suffered a net economic loss from CALRA and the events preceding its enactment. Since passage of the act, at least three effects have been verified: Relative to conditions that would otherwise have been expected to exist, consumers are facing higher prices; agricultural workers are earning lower wages; and landowners have suffered losses in land values.     

A decision support system for banks

Just recently, information systems with rather unique characteristics have begun to emerge. These systems usually referred to as Decision Support Systems, feature decision models, a data base and the decision maker as subsystems and are specifically oriented to supporting decision making. This article examines Decision Support Systems and their application to banks.     

A quadratic lower bound for colourful simplicial depth

We show that any point in the convex hull of each of (d+1) sets of (d+1) points in ℝ ^d is contained in at least ⌊(d+2)²/4⌋ simplices with one vertex from each set.
