Stylised features of consumer price setting behaviour in Portugal: 1992–2001

This paper identifies the empirical stylized features of consumer price setting behavior in Portugal using two micro-datasets underlying the consumer price index. The main conclusions are: one in every four prices change each month; there is a considerable degree of heterogeneity in price setting practices; prices of goods change more often than prices of services; price reductions are common, as they account to around 40% of total price changes; price changes are, in general, sizeable; finally, the price setting patterns seem to depend on the level of inflation as well as on the type of outlet.

The role of Spanish local development and employment officers in human resource management

The aim of this study is to contrast the existence of a significant relation between good human resource practices and business results. The empirical analysis is applied to strategies implemented by Local Development and Employment Officers (LDEOs) with regard to the management of social integration and job placement programs within the context of Local Development in Spain for both the universalist and contingent perspectives of Human Resource Management. The novelty of this study lies in the impact local development programs are having on social integration and job placement, and, in particular, the effects of project management.     

The impact of education,experience and inner circle advisors on SME performance: insights from a study of public development centers

In this study, we investigate the effects of entrepreneurial human capital on SME performance using data on 2,713 SMEs within the European Union. Performance was measured in two ways: profitability as ROA and productivity as revenue per employee. Results indicate that both profitability and productivity are positively related to industry-specific knowledge possessed by the CEO-owner prior to starting up the firm and the general business knowledge acquired once the firm is up and running. Experience as a result of having previously worked in a firm in the same industry before starting a business was related to productivity, but there is no relation with profitability. There is a link between performance and inclusion of other CEO-owners in the founder’s inner circle of advisors. This relationship is positive when the advisor’s venture has experienced failure and negative when the advisor’s venture has been successful. We discuss the significance of these findings for research and practice.     

The use of Fx derivatives and the cost of capital: Evidence of Brazilian companies

Large corporations have been using derivative instruments as a tool to protect their indirect exposure, as FX risks. A sample with 47 non-financial Bovespa Listed Brazilian companies from 2004 and 2010 was used to test the hypothesis that use of derivatives as a risk management policy tool reduces companies' cost of capital. In contrast to other countries, results rejected this hypothesis, showing that in Brazil there is a positive relationship between using these tools and cost of capital. However, a more in-depth analysis based on the TACC model for a Brazilian company, this hypothesis was not rejected after the 2008 crisis.     

Financial market models with Lévy processes and time-varying volatility

Asset management and pricing models require the proper modeling of the return distribution of financial assets. While the return distribution used in the traditional theories of asset pricing and portfolio selection is the normal distribution, numerous studies that have investigated the empirical behavior of asset returns in financial markets throughout the world reject the hypothesis that asset return distributions are normally distribution. Alternative models for describing return distributions have been proposed since the 1960s, with the strongest empirical and theoretical support being provided for the family of stable distributions (with the normal distribution being a special case of this distribution). Since the turn of the century, specific forms of the stable distribution have been proposed and tested that better fit the observed behavior of historical return distributions. More specifically, subclasses of the tempered stable distribution have been proposed. In this paper, we propose one such subclass of the tempered stable distribution which we refer to as the “KR distribution”. We empirically test this distribution as well as two other recently proposed subclasses of the tempered stable distribution: the Carr–Geman–Madan–Yor (CGMY) distribution and the modified tempered stable (MTS) distribution. The advantage of the KR distribution over the other two distributions is that it has more flexible tail parameters. For these three subclasses of the tempered stable distribution, which are infinitely divisible and have exponential moments for some neighborhood of zero, we generate the exponential Lévy market models induced from them. We then construct a new GARCH model with the infinitely divisible distributed innovation and three subclasses of that GARCH model that incorporates three observed properties of asset returns: volatility clustering, fat tails, and skewness. We formulate the algorithm to find the risk-neutral return processes for those GARCH models using the “change of measure” for the tempered stable distributions. To compare the performance of those exponential Lévy models and the GARCH models, we report the results of the parameters estimated for the S&P 500 index and investigate the out-of-sample forecasting performance for those GARCH models for the S&P 500 option prices.     

Risk parity portfolio optimization under a Markov regime-switching framework

We formulate and solve a risk parity optimization problem under a Markov regime-switching framework to improve parameter estimation and to systematically mitigate the sensitivity of optimal portfolios to estimation error. A regime-switching factor model of returns is introduced to account for the abrupt changes in the behaviour of economic time series associated with financial cycles. This model incorporates market dynamics in an effort to improve parameter estimation. We proceed to use this model for risk parity optimization and also consider the construction of a robust version of the risk parity optimization by introducing uncertainty structures to the estimated market parameters. We test our model by constructing a regime-switching risk parity portfolio based on the Fama–French three-factor model. The out-of-sample computational results show that a regime-switching risk parity portfolio can consistently outperform its nominal counterpart, maintaining a similar ex post level of risk while delivering higher-than-nominal returns over a long-term investment horizon. Moreover, we present a dynamic portfolio rebalancing policy that further magnifies the benefits of a regime-switching portfolio.     

Does culture influence IPO underpricing?

This paper examines how cultural differences influence cross-sectional variation in IPO underpricing across 39 countries. We conjecture that cultural difference across geographic boundaries will influence the acceptance of and the expectations for IPO underpricing. Cross-sectional differences in culture are measured using Hofstede's six cultural dimensions. Our analysis shows that high power distance and high long term orientation are significantly associated with higher IPO underpricing. We also show that underpricing is significantly lower in countries characterized by high uncertainty avoidance. When the model is expanded to include legal origin, market based and corporate governance variables, the three cultural factors remain significant. Our findings provide further evidence that culture impacts capital market returns. Overall, our finding that culture impacts IPO underpricing, suggests important implications for policy makers and investors.     

GROWTH AND INCOME POVERTY IN LATIN AMERICA AND THE CARIBBEAN: EVIDENCE FROM HOUSEHOLD SURVEYS

This paper provides evidence on growth and income poverty in Latin America and the Caribbean (LAC). Results are obtained by processing microdata from household surveys of 18 LAC countries covering the 1990s and early 2000s. Over this period the LAC economies experienced heterogeneous patterns of growth and poverty changes. Most countries in the region had a rather meager performance in terms of poverty reduction. Episodes of positive, significant and unambiguously pro-poor income growth have been rare in Latin America.     

Herd Behavior in Latin American Stock Markets

ABSTRACT

This article investigates the presence of herd behavior in Latin American stock markets using the methodologies proposed by Christie and Huang (1995 Christie , W. G. , &; Huang , R. D. ( 1995 ). Following the pied piper: Do individual returns herd around the market? Financial Analysts Journal , 51 ( 4 ), 31 – 37 .[Taylor &; Francis Online] , [Google Scholar]) and Chang, Cheng, and Khorana (2000 Chang , E. C. , Cheng , J. W. , &; Khorana , A. ( 2000 ). An examination of herd behavior in equity markets: An international perspective . Journal of Banking and Finance , 24 ( 10 ), 1651 – 1679 .[Crossref], [Web of Science ®] , [Google Scholar]). Daily closing prices and trading volumes from January 3, 2000 to September 15, 2010 from the stock markets of Argentina, Brazil, Chile, Mexico, and the United States were analyzed. The US market was studied in order to provide a reference for comparison. The shares for which data was collected in each country were those listed in the most representative stock index for each market. It was not possible to establish evidence of herd behavior in any of the five countries studied using the Christie and Huang (1995 Christie , W. G. , &; Huang , R. D. ( 1995 ). Following the pied piper: Do individual returns herd around the market? Financial Analysts Journal , 51 ( 4 ), 31 – 37 .[Taylor &; Francis Online] , [Google Scholar]) method. However, evaluating the data for the entire period using the method proposed by Chang, Cheng, and Khorana (2000 Chang , E. C. , Cheng , J. W. , &; Khorana , A. ( 2000 ). An examination of herd behavior in equity markets: An international perspective . Journal of Banking and Finance , 24 ( 10 ), 1651 – 1679 .[Crossref], [Web of Science ®] , [Google Scholar]) we detected herd behavior in the Chilean market. These results were not affected by the addition of additional exogenous variables representing the September 11 attacks of 2001 and the subprime crisis, or when the effect of the behavior of US shares on other countries was analyzed. Asymmetric herd behavior was detected in the Chilean, United States, Argentinean, and Mexican markets.
