A Note on Time Discretion and the Welfare Cost of Lump-Sum Taxation  [PDF]
Cristian F. Sepulveda
Theoretical Economics Letters (TEL) , 2018, DOI: 10.4236/tel.2018.82013
Abstract: The lump-sum tax is broadly regarded by standard optimal tax theory as the only non-distortionary tax instrument; any other tax instrument distorts relative prices and thus creates a deadweight loss. This paper discusses an unintended effect of lump-sum taxation that can be considered a distortion of the time endowment. Whenever this tax exceeds the amount of non-labor income, it reduces the taxpayer’s ability to freely allocate her time endowment. As long as the taxpayer assigns a positive value to time discretion, the lump-sum tax creates a welfare cost that has not been identified in the relevant literature. The welfare cost of the lump-sum tax could plausibly be greater than the traditional measure of deadweight loss of an equal yield labor income tax, which does not affect time discretion. Since the lump-sum tax does not unambiguously lead to a greater welfare level, we can conclude that it is not a proper efficiency standard at low levels of non-labor income. The same argument can be used to call for caution in the use of taxes based on the value of assets that are not the source of income flows, like owner-occupied property taxes and some types of wealth taxes. At low levels of non-labor income, these tax instruments will also have a negative effect on time discretion.

Abstract: the laser use has had a constant evolution and development; the bioestimulantion effects have been verified in numerous studies that the irradiation laser of fall promotes produces on having interacted with cells and tissues this study tries to determine the morphologic differences in the oral mucous injured, after the application of low-level laser, across changes in the vascular density of the subpapilar plexus of the mucous oral. fifteen sprague dawley mice were used, which formed three groups, in the total number of animals the oral mucous was injured, in the average zone of the labial low frenum. group i was taken as a control; in group ii a low-level laser was applied on the mucous immediately the oral injury, then, at 48 after 24 hours in a dose of 6 joule/cm2 for application; group iii a low-level laser in a single dose of 18 joule/cm2 was applied immediately the oral injury. the unit of sample and analysis they were the histological cuts obtained of the section of the oral mucous injured. the results show a major vascular density in the group the ii with regard to the group i and the iii, with a density i mediate of 4,07 vassels/25mm2, while the group i of 2,47 vassels/25mm2 and group ii of 1,87 vassels/25mm2. no find differences between groups i and iii. these results indicate that the application of low-level laser in low dose originate an increase in the vascular density in the oral mucous injured

Abstract: La utilización del láser ha tenido una constante evolución y desarrollo. Se ha comprobado en numerosos estudios los efectos bioestimulantes que la irradiación láser de baja potencia produce al interactuar con los tejidos y células. Este estudio pretende determinar la existencia de diferencias morfológicas en la mucosa oral lesionada, posterior a la irradiación con láser de baja potencia, a través de cambios en la densidad vascular del plexo subpapilar de la mucosa oral. Se utilizaron 15 ratas Sprague Dawley, las cuales se dividieron en tres grupos. A la totalidad de los animales se les lesionó la mucosa oral, en la zona media del frenillo labial inferior. El grupo I se tomó como control; al grupo II se le aplicó láser de baja potencia sobre la mucosa oral inmediatamente realizada la lesión, luego, a las 24 y 48 horas, en una dosis de 6 Joule/cm2 por aplicación; al grupo III se le aplicó láser de baja potencia en una dosis única de 18 Joule/cm2 inmediatamente efectuada la lesión. La unidad de muestra y análisis fueron los cortes histológicos obtenidos de la sección de la mucosa oral lesionada. Los resultados muestran una mayor densidad vascular en el grupo II con respecto a los grupos I y III, con una densidad promedio de 4,07 vasos sanguíneos/25mm2, mientras el grupo I de 2,47 vasos sanguíneos/25mm2 y el grupo III de 1,87 vasos sanguíneos/25mm2. No se observó diferencia entre las densidades obtenidas para los grupos I y III. Estos resultados indican que la aplicación de láser de baja potencia en dosis baja produce un aumento en la densidad vascular en la mucosa oral lesionada The laser use has had a constant evolution and development; the bioestimulantion effects have been verified in numerous studies that the irradiation laser of fall promotes produces on having interacted with cells and tissues This study tries to determine the morphologic differences in the oral mucous injured, after the application of low-level laser, across changes in the vascular density of the subpapilar plexus of the mucous oral. Fifteen Sprague Dawley mice were used, which formed three groups, in the total number of animals the oral mucous was injured, in the average zone of the labial low frenum. Group I was taken as a control; in group II a low-level laser was applied on the mucous immediately the oral injury, then, at 48 after 24 hours in a dose of 6 Joule/cm2 for application; Group III a low-level laser in a single dose of 18 Joule/cm2 was applied immediately the oral injury.

Abstract: Toronto Alexithymia Scale (TAS-20) adolescent research became increasingly popular. We found no data examining two different ethnical adolescent groups sharing comparable environment. Furthermore, there are no indications that TAS-20 has ever been used in Chile. We conducted a transcultural comparison investigating the influence of ethnicity, gender and age on a low socioeconomic teenage population. Additionally, Confirmatory Factor Analysis (CFA) was performed. In this cohort study (n = 225), 95 indigenous students were compared to the Hispanic control group of 130 participants. We found proper replicability and internal reliability of TAS-20 and the three-factor solution for our sample. We measured high alexithymia rates and significant differences between the ethnicities and genders but there was no influence of age. Although factor 3 (EOT) was inconsistent to some degree, TAS-20 resulted to be an appropriate measure for Chilean adolescents. Indigenous ethnicity, gender, low socioeconomic status, and power distance in a rural environment contribute to high alexithymia.

Abstract: background: earlier reports have shown that performing operations in fed, opposed to overnight-fasted patients, has several benefits. preoperative patients receiving carbohydrates were found to be less hungry and less anxious than those receiving placebo or those fasting overnight. preoperative oral carbohydrate loading on the day of operation may diminish the organic response to trauma. aim: to investigate the effects of preoperative carbohydrate-rich drinks regarding gastrointestinal symptoms after cholecystectomy. methods: randomized prospective trial. a total of 54 female patients (average age = 42[19-69] years-old) scheduled for elective cholecystectomy were randomized to receive either a beverage containing 12.5% carbohydrate, 6 (400 ml) and 2 hours (200 ml) before surgery (group carbohydrate n=28) or fasting for 6-8 hours (control group n=26). parameters investigated included the occurrence of vomit, nausea, abdominal distention, passage of flatus and feces, and the length of postoperative hospital stay. results: abdominal distension (42.3 vs 17.8%; p = 0,04), episodes of vomiting (53.8% vs 21.4%; p = 0,01), the presence of two or more associated gastrointestinal symptoms (73.1% vs 39.3%; p = 0,01), and the length of postoperative hospital stay (2 [1-3] vs 1 [1-3] days; p = 0,04) was significantly smaller in the carbohydrate control group. conclusion: preoperative oral carbohydrate administration reduces both postoperative gastrointestinal discomfort and postoperative hospital stay after cholecystectomy.
