Secular Stagnation or Stagnation Policy? Steindl after Summers [PDF]
SSRN Electronic Journal, 2015 The debate on secular stagnation suffers from vagueness and several shortcomings, which affect its economic policy implications. In this work we provide an alternative view on the advanced economies’ tendencies to stagnation, based on Josef Steindl’s contributions.

The effect planting hole size and manure on vegetative growth of golden teak (Tectona grandis L.)
Journal of Degraded and Mining Lands Management, 2018 Cultivation of the golden teak (Tectona grandis L.) requires the planting hole size and appropriate use of manure. The size of planting hole provides plant growth, so that the plant can grow with optimum and appropriate use of manure to provide nutrients
