The role of biota as a natural resource for the restoration of degraded chernozems of the Republic of Moldova is under discussion till nowadays. The status of biota of old-arable chernozems in conditions of the green manure applications has been evaluated statistically. Two experimental sites...

Statistical parameters, criteria and scales of the soil biota stability to the natural and anthropogenic impact in the Republic of Moldova has been developed. The modifications of the biological properties of soils as a result of their long-term arable use and the impacts of erosion processes...

The role of invertebrates and their contribution in functioning of soils is considered. The edaphic fauna of zonal untouched soils in natural ecosystems located in the different zones of the Republic of Moldova has been investigated. Soils of the natural ecosystems are the habitat and the source...

Several recent papers argue that contracts provide reference points that affect ex post behavior. We test this hypothesis in a canonical buyer-seller relationship with renegotiation. Our paper provides causal experimental evidence that an initial contract has a highly significant and...

We present an international trade model with multiproduct firms. Firms are heterogeneously endowed with two types of capabilities that jointly determine the trade-off within firms between managing a large portfolio of products and producing at low marginal cost. The model can explain many of the...
