Human resources audit

Human resource management (HRM) has experienced a strong evolution. In order to provide useful information to managers, it is necessary to evaluate the results generated by the design and implementation of personnel policies. This is the goal of the HR audit that includes two different analyses and valuations: the HR policies and their level of fit with the strategy of the firm, and the characteristics of human capital. Several criteria have been used to assess different HR policies. Nevertheless, the measurement of the value that human capital brings to the firm is a very complex topic. Consequently, different models are being presented that aim to properly solve this challenge. This paper will analyze the HR function from two perspectives: the evaluation of the implemented policies and the quality of human capital in relation to real competencies, and the capability to learn and develop new skills.     

American GARCH employee stock option valuation

We implement a flexible simulation-based approach for the fair value of employee stock option (ESO) that accounts for the vesting period, departure risk and voluntary suboptimal early exercise. We introduce GARCH effects on the underlying asset and we analyze the price bias with respect to the constant volatility case. We also perform a sensitivity analysis with respect to changes in several ESO characteristics. We compare this valuation with FAS 123 method revealing a FAS overvaluation. Finally, we value a real ESO plan providing the confidence intervals for the estimated ESO prices.     

Trading with Asymmetric Volatility Spillovers

Abstract:  We study the profitability of trading strategies based on volatility spillovers between large and small firms. By using the Volatility Impulse-Response Function of Lin (1997) and its extensions, we detect that any volatility shock coming from small companies is important to large companies, but the reverse is only true for negative shocks coming from large firms. To exploit these asymmetric patterns in volatility, different trading rules are designed based on the inverse relationship existing between expected return and volatility. We find that most strategies generate excess after-transaction cost profits, especially after very bad news and very good news coming from large or small firm markets. These results are of special interest because of their implications for risk and portfolio management.     

How wide is the gap? An investigation of gender wage differences using quantile regression

In this paper we re-examine the link between subjective perceptions and objective measures of wage discrimination by estimating the mean and several quantiles in the conditional wage distribution of men and women in order to decompose the gender wage gap into the part attributed to different characteristics and the part attributable to differential returns to these characteristics at points other than the conditional expectation. In the process we take into account the endogeneity of educational choice and the participation decision of women. The results suggest that the absolute wage gap and the component of the latter that can be attributed to different returns to characteristics increase over the wage scale.     

Expropriation risk and housing prices: Evidence from an emerging market

This paper examines the microeconomic determinants of residential real estate prices in Caracas, Venezuela, using a private database containing 17,526 transactions from 2008 to 2009. The particular institutional characteristics of many countries in Latin America, and Venezuela in particular, where land invasions and expropriations (with only partial compensation) have been common threats to property owners, provide us with an opportunity to test the effects of these risks on housing prices using a unique database. The effect of these risks on property prices is negative and significant. To our knowledge, this is the first attempt to quantify these impacts in the Hedonic pricing literature applied to real estate. Size, the number of parking spaces, the age of the property, the incidence of crime, and the average income in the neighborhood are significant determinants of prices. Finally, this paper analyzes the microeconomic determinants of housing prices at the municipal level.     

Citizen involvement in promoting sustainable mobility

This article proposes a methodology for promoting public involvement in the planning process for the promotion of sustainable mobility. The concept of the focus group (FG) is widened and a method based on holding larger groups defined as mega focus groups (MFG) is proposed. These MFG allow all sections of society to be represented in the participation process, thereby involving the population at a strategic level in subjects of general interest to society and later, holding smaller FGs on more specific subject matters (tactical level).The advantage of the larger MFG over the smaller FG is that they can obtain more information (between 40 and 60 people take part) from easily run meetings (similar to the FG). The MFG also provide a territorial representation of peoples’ opinions and serve as a mechanism for selecting the participants in the smaller focus groups. The information extracted from both the MFG and FG about people’s perceptions of sustainable mobility provides the background to the design of pilot surveys on urban mobility. For a better understanding of the development of this method and its possible applications in any town or city the article includes its practical application in the medium sized city of Santander (Northern Spain).     

Understanding the drivers of organizational innovations

Organizational innovations involve the implementation of significant changes in business practices, the workplace organization, and external relations. The article reports an analysis of organizational innovations' objectives and adoption in 240 Spanish healthcare businesses. Statistical tests find a dynamic behavior in healthcare organizations with 40.8% having developed an organizational innovation in the period from 2007 to 2009. The main objectives pursued are related to improved knowledge sharing and innovation skills. Results also reveal a close relationship between organizational and product/process innovations. Specifically, healthcare companies developing new organizational methods to improve innovation skills and knowledge sharing are more successful in adopting product and process innovations.     

Consumer receptiveness to international retail expansion: a cross-cultural study of perceptions of social and economic influence of foreign retailers

Guided by the work of Samiee (1993 Samiee, S.1993. “Retailing and Channel Considerations in Developing Countries: A Review and Research Propositions.” Journal of Business Research27 (2): 103–129. doi:10.1016/0148-2963(93)90018-K.[Crossref], [Web of Science ®] , [Google Scholar]. Journal of Business Research, 27 (2): 103–129), Sakarya, Eckman, and Hyllegard (2007 Sakarya, S., M.Eckman, and K.Hyllegard. 2007. “Market Selection for International Expansion.” International Marketing Review24 (2): 208–238. doi:10.1108/02651330710741820.[Crossref], [Web of Science ®] , [Google Scholar]. International Marketing Review, 24 (2): 208–238), and Alexander et al. (2010 Alexander, N., A. M.Doherty, J. M.Carpenter, and M.Moore. 2010. “Consumer Receptiveness to International Retail Market Entry.” International Journal of Retail & Distribution Management38 (3): 160–172. doi:10.1108/09590551011027104.[Crossref] , [Google Scholar]. International Journal of Retail & Distribution Management, 38 (3): 160–172), a cross-cultural analysis was undertaken to examine consumer receptiveness to domestic market entry by foreign apparel specialty retailers. More specifically, this study explored differences in consumers' perceptions of the influence of foreign apparel specialty retailers on social, cultural, and economic development across three countries: Spain, Turkey, and the USA. Consumer receptiveness was measured as beliefs about the social and economic influence of foreign retailers and perceptions of retailers' brand characteristics and offerings. An intercept survey of 1233 apparel shoppers was conducted in major metropolitan shopping areas in all three countries. MANOVA revealed that Spanish consumers were least concerned about urban growth associated with foreign retailers and least likely to perceive positive employment/business opportunities and socio-cultural well-being from the presence of foreign retailers. Turkish consumers held the strongest perceptions regarding the influence of foreign retailers on urban growth. Paired sample t-tests revealed that Turkish consumers, when compared with Spanish consumers, evaluated U.S. retailers' offerings more positively and were more receptive to the entry of U.S. retailers into their domestic markets. Results of regression analyses indicated that Spanish and Turkish consumers' beliefs about retail brand characteristics and the socio-cultural and economic influence of foreign retailers positively predicted consumers' receptiveness, whereas age negatively influenced receptiveness. Differences in perceptions among Spanish, Turkish, and U.S. consumers may be attributed to the varying levels of economic development among the three countries as well as to the countries' differing policies concerning foreign retailers. Findings provide a basis for the development of a measure of consumer receptiveness to international retail expansion.
