This examination of the role and potential for replication in economics points out the paucity of both pure replication – checking on others’ published papers using their data – and scientific replication – using data representing different populations in one’s own work or in a comment. Several controversies in empirical economics are used to illustrate how and how not to behave when replicatin...

This paper introduces and discusses an heuristic model meant to clarify why and how economic instability may play a crucial role in a modern sophisticated monetary economy. In this model economic instability is specified in terms of structural instability rather than in the usual terms of dynamic instability. This different view of instability implies a different approach to the analysis of the...

An experimental study is presented on the effect of Conservation Agriculture (CA) compared to Conventional Agriculture (ConvA) upon Maize Yield based on split-plot model. Two factors have been considered: A Factor-Fertilization with two variants: A1N40P40 kg/ha and A2N90P70 kg/ha; B FactorCrop protection with 4 variants : B14 treatments, B2-3 treatments, B32 treatments and B41 treatment. In com...

A contiguous region of about 30 kbp of DNA putatively encoding reactions in daunomycin biosynthesis was isolated from Streptomyces sp. strain C5 DNA. The DNA sequence of an 8.1-kbp EcoRI fragment, which hybridized with actI polyketide synthase (PKS) and actIII polyketide reductase (PKR) gene probes, was determined, revealing seven complete open reading frames (ORFs), two in one cluster and five...

milton friedman’s seminal article, “methodology of positive economics”, is one of the most important and contentious works ever been discussed within the realm of economic methodology. in this article, on the basis of an instrumentalist approach to the nature of theorizing, friedman declares the tenets of positive economics, and in this vein, he professes his disputable doctrine about “unrealis...

The objective of the paper is threefold. First, to argue that some of Haavelmo’s (1944) methodological ideas and insights have been neglected because they are largely at odds with the pre-eminence of theory perspective that dominates empirical modeling in economics. Second, to make a case that this neglect has contributed to the unreliability of empirical evidence in economics; a key contributo...

It is established that interpretation essence and strategy financing in practice has quite different approaches. been proven formation an effective system involves relationship redistribution between sources resources. substantiated agriculture a...
