Worker displacement in Russia and Ukraine: a comparative analysis using micro data
No full textUsing unique data from a supplement to the RLMS on displaced workers in Russia and from the Ukrainian Longitudinal Monitoring Survey (ULMS) we analyze and provide the first solid evidence on displacement in Russia and Ukraine in a period of growth. Our estimates establish that quits dominate separations but that displacement rates are clearly not negligible amounting to between 2.5 and 3 percent of employment in Russia and between 2 and 5 percent in Ukraine. We also show that displacements are not random. Results that are valid across both countries demonstrate that unskilled and less educated workers are more affected as are workers in the agricultural sector. In countries like Russia and Ukraine where unemployment benefits are not generous or non-existent for the average worker long spells of non-employment can impose large monetary costs on workers. Presenting cumulative return rates for job movers we point to these costs by highlighting the fact that there is a very sizable privileged group of displaced workers who finds a new job within a very short time while the majority has difficulty in finding new employment. This latter group is associated with low educational attainment and low skills. It is this group (larger in Ukraine than in Russia), which is not so rapidly absorbed by the labor market, that should be the target of social policy intervention by the Russian and Ukrainian governments

Hodges-Lehmann Optimality for Testing Moment
No full textThis paper studies the Hodges and Lehmann (1956) optimality of tests in a general setup. The tests are compared by the exponential rates of growth to one of the power functions evaluated at a fixed alternative while keeping the asymptotic sizes bounded by some constant. We present two sets of sufficient conditions for a test to be Hodges-Lehmann optimal. These new conditions extend the scope of the Hodges-Lehmann optimality analysis to setups that cannot be covered by other conditions in the literature. The general result is illustrated by our applications of interest: testing for moment conditions and overidentifying restrictions. In particular, we show that (i) the empirical likelihood test does not necessarily satisfy existing conditions for optimality but does satisfy our new conditions; and (ii) the generalized method of moments (GMM) test and the generalized empirical likelihood (GEL) tests are Hodges-Lehmann optimal under mild primitive conditions. These results support the belief that the Hodges-Lehmann optimality is a weak asymptotic requirement.Asymptotic optimality, Large deviations, Moment condition, Generalized method of moments, Generalized empirical likelihood

Data From: Ammonia volatilization from composting with oxidized biochar
No full textPlease cite as: Rachel Hestrin, Akio Enders, and Johannes Lehmann. (2020) Data From: Ammonia volatilization from composting with oxidized biochar. Cornell University eCommons Repository. https://doi.org/10.7298/p9wj-nk83Data in support of the following research: Animal manure, agricultural residues, and other sources of biomass can be diverted from the waste stream and composted into valuable fertilizer. However, composting often results in substantial N loss through NH3 gas volatilization. We investigated biochar’s capacity to improve NH3–N retention during composting of poultry manure and straw. After 7 weeks, total NH3–N loss from composting with unoxidized biochar was twofold and sixfold higher than N loss from composting with oxidized biochar and without biochar (307, 142, and 51 mg N g-1 N in the initial compost feedstocks, respectively). When cumulative NH3–N loss was calculated relative to CO2–C loss to account for differences in microbial activity, NH3–N:CO2–C loss from compost with oxidized biochar was 55% lower than from compost with unoxidized biochar (82% lower based on mass balance). Oxidized biochar particles removed from compost after 7 weeks retained 16.0 mg N g-1 biochar, compared to only 6.1 mg N g-1 retained by unoxidized biochar, suggesting that N retention by biochar particles provides a mechanism for reduced NH3–N loss. These data show that oxidized biochar enhanced microbial activity, doubled composting rate, and reduced NH3–N loss, and that biochar’s physiochemical characteristics modulate its performance in compost. In particular, the presence of oxidized surface functional groups—which can be increased artificially or through environmental weathering—appear to play an important role in key compost processes. This has implications for other natural and managed systems where pyrogenic organic matter may mediate biological activity and nutrient cycles
