SPORTS,EXERCISE, AND LENGTH OF STAY IN HOSPITALS: IS THERE A DIFFERENTIAL EFFECT FOR THE CHRONICALLY ILL PEOPLE?

This paper examines the effects of sports and exercise on hospital stays for males and females by various chronic conditions using a panel dataset from Canada. The results suggest that moderately active and active individuals have shorter hospital stays than inactive individuals. On average, individuals with moderate to higher amount of physical activity stay 36% to 39% less than inactive individuals. Physical activity has consistent impact on hospital stays for the entire population as well as subgroup of people with or without chronic conditions. However, its effect is substantially larger for people with chronic conditions, especially for those who have diabetes, cancer, high blood pressure, heart disease, and stroke. The paper also suggests that additional exercise once moderate level of exercise is achieved does not generate substantially large benefits in the form of shorter hospital stays. Hence, it provides additional evidence to support the recent physical activity guidelines for adults that highlight health benefits of moderate amount of regular physical activity. (JEL I1)     

Linking of Manufacturing Strategy,Market Requirements and Manufacturing Attributes In Technology Choice: An Expert System Approach

This paper suggests a framework for acquisition of new manufacturing technology that links the manufacturing strategy, market requirements and manufacturing attributes using an expert system approach. This paper takes a closer took at traditional notion of manufacturing-marketing coordination and attempts to find its links with manufacturing capabilities provided by recent evolving new manufacturing technology. For this purpose we deal with different steps involved in the strategic evaluation process beginning with the choice of a suitable competitive strategy by a firm. Then the chosen competitive strategy is linked with the market requirements, system attributes and appropriate manufacturing technology choices. The proposed model is integrated by an expert system approach that includes strategic factors of both a tangible and an intangible nature and is implemented by using the VP-Expert shell.     

Nuevos indicadores de los derechos laborales. Método y tendencias en 2000–2015

Se describe un nuevo método para elaborar indicadores de los derechos de libertad sindical y de negociación colectiva mediante la codificación de infracciones en nueve fuentes documentales, seis de ellas de la OIT, e instrumentos legislativos nacionales. Los indicadores calculados, correspondientes a 185 Estados Miembros de la OIT para cinco años entre 2000 y 2015, se publicaron en 2015 por iniciativa del Center for Global Workers' Rights y la Global Labour University. En octubre de 2018 la Conferencia Internacional de Estadísticos del Trabajo recomendó adoptar esta metodología para el indicador 8.8.2 de los Objetivos de Desarrollo Sostenible relativo a los derechos laborales.     

Differences across Cohorts in Finnish Intergenerational Income Mobility

Trends in intergenerational economic mobility in Finland are analyzed using panel data from 1950 through 1999 on more than 250,000 sons and daughters born between 1930 and 1970. A significant decline is estimated in the intergenerational transmission elasticity from the 1930 birth cohort until the baby boom cohorts of the early 1950s. After that we observed no increase in the extent of mobility for 1950s and 1960s birth cohorts, but rather the reverse. The result holds both for sons and daughters. A decomposition of the intergenerational transmission elasticities across cohorts shows that most of the early decline in transmission reflected a drop in the influence of parental income on the children's earnings that operated through investments in the child's schooling. This early pattern is postulated to reflect the phases of secondary educational expansion at the time. Throughout, a rise is estimated in the intergenerational transmission elasticity with age at which sons and daughters are observed. This has also been noted in prior U.S. studies and, at least in this Finnish context, this seems to result almost entirely from rising estimated returns to education with age.     

RELATIONSHIPS AMONG STRATEGIC COMMODITIES AND WITH FINANCIAL VARIABLES: A NEW LOOK

We examine the comovements among the prices of four strategic commodities that have long, adequate daily series: oil, gold, silver, and copper as a group. We also explore their causal relationships with two commodity-relevant macrofinancial variables: interest and exchange rates as an expanded group to shed some light on the prediction behaviors of those individual commodity prices relative to the selected financial variables. In the expanded group, the selected interest rate can provide a transmission link between commodity prices and the dollar exchange rate. The results and their policy implications are discussed at length . ( JEL C51, E27, Q43)
