Labor Participation of Married Women in Colombia

A pseudo-panel was built to estimate the determinants of the labor participation decision of married women between 1984 and 2000. Past participation decisions, education level, labor income taxes, children between 1 and 2 years of age, and the presence of other people unemployed at home are the main explanatory variables of married women’s labor participation in Colombia . The interest rate variable does not offer any insight into that decision.married women, labor participation, state-dependence, fertility.

Unemployment Rate and the Real Wage Behavoir: A Neoclassical Hint for the Colombian Labor Market Adjustment

The colombian urban unemployment rate grew dramatically over the last six years. At the same time the real wage also had a sharp increase: The empirical evidence supports the hypothesis that an exogenous increase in the real wage was a cause of the unemployment growth. The long-run elasticity suggest that one percent increase of the real wage index increases unemployment rate something between 0.7 and 1.0 percent. Therefore it seems necessary that real wage comes back to its equilibrium path for the reduction of the unemployment rate to the natural level.Unemployment rate, real wage, cointegration, long-run elasticities.

The Time-Varying Long-Run Unemployment Rate: The Colombian Case

The long-run component of the Colombian unemployment rate is estimated for the last twenty years. According to the results, the main determinants of the permanent component of the unemployment rate are the real hourly wage, the non-wage labor costs and the rate of capital accumulation. Given the statistical properties of the variables, a cointegration approach was adopted.Unemployment rate, labor costs, capital accumulation, cointegration

Experimentally Attainable Optimal Pulse Shapes Obtained with the Aid of Genetic Algorithms

We propose a methodology to design optimal pulses for achieving quantum optimal control on molecular systems. Our approach constrains pulse shapes to linear combinations of a fixed number of experimentally relevant pulse functions. Quantum optimal control is obtained by maximizing a multi-target fitness function with genetic algorithms. As a first application of the methodology we generated an optimal pulse that successfully maximized the yield on a selected dissociation channel of a diatomic molecule. Our pulse is obtained as a linear combination of linearly chirped pulse functions. Data recorded along the evolution of the genetic algorithm contained important information regarding the interplay between radiative and diabatic processes. We performed a principal component analysis on these data to retrieve the most relevant processes along the optimal path. Our proposed methodology could be useful for performing quantum optimal control on more complex systems by employing a wider variety of pulse shape functions.Comment: 7 pages, 6 figure

How do you pay? The role of incentives at the point-of-sale

This paper uses discrete-choice models to quantify the role of consumer socioeconomic characteristics, payment instrument attributes, and transaction features on the probability of using cash, debit card, or credit card at the point-of-sale. We use the Bank of Canada 2009 Method of Payment Survey, a two-part survey among adult Canadians containing a detailed questionnaire and a three-day shopping diary. We find that cash is still used intensively at low value transactions due to speed, merchant acceptance, and low costs. Debit and credit cards are used more frequently for higher transaction values where safety, record keeping, the ability to delay payment and credit card rewards gain prominence. We present estimates of the elasticity of using a credit card with respect to credit card rewards. Reward elasticities are a key element in understanding the impact of retail payment pricing regulation on consumer payment instrument usage and welfare.
