Bounds on counterfactual distributions under semi-monotonicity constraints
Boes, Stefan - 2009
This paper explores semi-monotonicity constraints in the distribution of potential outcomes, first, conditional on an instrument, and second, in terms of the response function. The imposed assumptions are strictly weaker than traditional instrumental variables assumptions and can be gainfully...

Asymmetry reversals and the business cycle
Distante, Roberta; Petrella, Ivan; Santoro, Emiliano - 2013
The cross-sectional dynamics of the U.S. business cycle is examined through the lens of quantile regression models. Conditioning the quantiles of firm-level growth to different measures of technological change highlights a deep connection between counter-cyclical skewness and the transmission of...

Neoclassical convergence versus technological catch-up : a contribution for reaching a consensus
Desdoigts, Alain - 2002
New macro empirical evidence is provided to assess the relative importance of object and idea gaps in explaining the world income distribution dynamics over a benchmark period 1960-1985. Results are then extended through 1995. Formal statistical hypothesis tests allow us to discriminate between...
