Corporate Taxes and Firms’ Performance: Evidence from an Emerging Economy

Corporate taxes play an important role in a firm’s decision-making as they are part of the cost of capital. Thus, understanding the effect of taxes on the performance of firms in the context of frequent tax reforms, as is the case of Colombia, is of great relevance. We used the meta-frontier stochastic techniques, which allow us to estimate in two steps the technical efficiency of firms within each economic sector and between economic sectors in relation to the set of firms in the country. Then, using quantile regression analysis, we estimate both the effect of corporate taxation on firm performance as well as the effect of efficiency on firms’ tax payments. Results indicate that firms in some economic sectors could be benefiting from better production conditions, and that the most efficient firms within each sector paid more taxes as a share of assets. However, when compared to the meta-frontier, firms with higher efficiency paid less taxes, suggesting differences in the firms’ tax burden across economic sectors

Health status and labor force participation : evidence for urban low and middle income individuals in Colombia

This paper analyzes the relationship between individual health status and labor force participation using the first wave of the Colombian Longitudinal Survey. The empirical modeling strategy accounts for the presence of potential endogeneity between these two variables. The results show that there is a positive relationship between health and labor force participation in both directions, indicating that better health is likely to lead to a higher probability of participation in the labor market, but also that individuals who participate in the labor market are more likely to report better health. Interesting differences are uncovered when comparing the results by gender and/or age groups. For instance, for younger females, health status and higher education positively affect the probability of labor participation, whereas having children under the age of 5 and being married reduce their probability of participation. Our findings also highlight the importance of public policy to guarantee good health conditions of the population which could also have a positive impact on labor productivity and consequently on long-run economic growth.info:eu-repo/semantics/publishedVersio

Constraints on the χ_(c1) versus χ_(c2) polarizations in proton-proton collisions at √s = 8 TeV

The polarizations of promptly produced χ_(c1) and χ_(c2) mesons are studied using data collected by the CMS experiment at the LHC, in proton-proton collisions at √s=8  TeV. The χ_c states are reconstructed via their radiative decays χ_c → J/ψγ, with the photons being measured through conversions to e⁺e⁻, which allows the two states to be well resolved. The polarizations are measured in the helicity frame, through the analysis of the χ_(c2) to χ_(c1) yield ratio as a function of the polar or azimuthal angle of the positive muon emitted in the J/ψ → μ⁺μ⁻ decay, in three bins of J/ψ transverse momentum. While no differences are seen between the two states in terms of azimuthal decay angle distributions, they are observed to have significantly different polar anisotropies. The measurement favors a scenario where at least one of the two states is strongly polarized along the helicity quantization axis, in agreement with nonrelativistic quantum chromodynamics predictions. This is the first measurement of significantly polarized quarkonia produced at high transverse momentum
