The dire economic situation in Mexico, with its high rate of unemployment, makes it necessary for many women to find some form of economic activity to provide income for their families. Although such conditions could encourage the creation of new firms, the results of the Global Entrepreneurship Monitor 2006 Report show a gap between the number of women involved in nascent and young entrepreneurship initiatives and the number who owns established firms. This gap may indicate that the firms created need to improve their competitiveness and their ability to survive. The model proposed adopts the resource‐based view of the firm as a theoretical framework from which to study how entrepreneurial orientation, market orientation, and learning orientation, as well as the interactions between them, influence the achievement of competitive advantage and superior performance in businesses owned by women. Our investigation analyzes businesses established and managed by women in Mexico and registered with the Asociación Mexicana de Mujeres Empresarias A.C. (Mexican Association of Business Women) and the Red de Empresarias del Instituto Nacional de Mujeres (Women Entrepreneurs Network of the National Women's Institute). To gather the information needed, the study used a questionnaire as a measuring instrument. The results are based on the 90 complete answers received from the questionnaires distributed. The results show that all of relationships in our model are positive except the hypothesis that learning orientation mediates in the relationship between market orientation and performance. The results suggest that entrepreneurial orientation reinforces the effect of two capabilities, market orientation and learning orientation, on firm performance. They also reaffirm that the three capabilities assessed may lead an organization to differentiate itself from its competitors by improving its performance. In addition to contributing to the literature on female entrepreneurship, the results have important implications for management. Understanding the relationships between capabilities and the performance of women‐owned businesses in Mexico can permit the identification of areas for improvement to promote the growth and survival of this type of firm.  相似文献

This research work analyzes the yields of the exchange rate parities of the American dollar, Canadian dollar, Euro, and Yen; estimates the basic statistics and the α-stables; carries out the Kolmogorov–Smirnov, Anderson–Darling, and Lilliefors goodness of fit tests; estimates the self-similar exponents and carries out the t and F tests, ruling out that the series of parities are multifractal. It also estimates the confidence intervals of the exchange rate parities and concludes that the estimated α-stable distributions are more efficient than the Gaussian distribution to quantify the risks of the market, and that the series are self-similar. Through the ? index, we can infer the risk of the events, indicating that the parities are anti-persistent and thus have short-term memory, mean reversion, and a negative correlation with the high risk in the short and medium term. The estimation and validation of the α-stable distributions and the self-similar exponent are important in the evaluation and creation of innovative investment instruments through financial engineering, risk administration, and the evaluation of derived products.  相似文献

The goal of this paper is to analyze the impact of annual earnings announcements on the market through the order flow data in addition to the usual transaction data. In this respect, examining order flow data can potentially reveal valuable information that is not available from transaction data. In fact, the data allow us to test hypotheses about asymmetric information and investor behavior and to test if the behavior varies with investor sophistication. In addition, the paper tries to identify the determinants of the impact on a firm's value using assumptions about investor behavior.  相似文献

La revolución de las TIC ha generado un alto riesgo de deslocalización de las tareas más comercializables en el sector de los servicios. Se revisan aquí estudios que proponen indicadores de comerciabilidad de los servicios, exploran las implicaciones de su deslocalización y desarrollan modelos teóricos al respecto. Tanto el nivel de calificación requerido como la comerciabilidad podrían ser determinantes clave de los efectos sobre los salarios y el empleo. Sin embargo, la falta de definiciones consensuadas de comerciabilidad y de datos fiables sobre el comercio de servicios, junto con la dificultad de evaluar la competencia de las importaciones a niveles desagregados, obstaculizan el avance de los estudios empíricos y descubren áreas para futuras investigaciones.  相似文献

Factor models have been applied extensively for forecasting when high‐dimensional datasets are available. In this case, the number of variables can be very large. For instance, usual dynamic factor models in central banks handle over 100 variables. However, there is a growing body of literature indicating that more variables do not necessarily lead to estimated factors with lower uncertainty or better forecasting results. This paper investigates the usefulness of partial least squares techniques that take into account the variable to be forecast when reducing the dimension of the problem from a large number of variables to a smaller number of factors. We propose different approaches of dynamic sparse partial least squares as a means of improving forecast efficiency by simultaneously taking into account the variable forecast while forming an informative subset of predictors, instead of using all the available ones to extract the factors. We use the well‐known Stock and Watson database to check the forecasting performance of our approach. The proposed dynamic sparse models show good performance in improving efficiency compared to widely used factor methods in macroeconomic forecasting. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

We empirically analyze the impact of product market competition on the responsiveness of inflation to macroeconomic imbalances. If competition is high the response of inflation to lagged inflation, unemployment and import prices is reduced, while inflation is more responsive to changes in productivity growth in countries in which competition is above the OECD average. Given the (‘good luck’) macroeconomic trajectories of the 1990s–2000s, the structural reforms that made goods markets more competitive improved the ability of OECD economies to smooth (dis)inflationary shocks, while changes in the monetary policy framework had a modest role in taming inflation during the Great Moderation.  相似文献

Multidisciplinary innovation is the main engine of growth for an increasing number of economies. Innovation requires the participation of and interaction between all economic agents. It also requires public spending on education, research and infrastructures. Our main goal is to emphasize the government's role in a growing innovation economy. Developing a non‐scale, idea‐based, one‐sector growth model with complementarities and productive public expenditure, we analyse theoretically the growth effects of an increase in productive public expenditure, which we find positive in the short, medium and long run.  相似文献
