New Evidence from Brazil on Trade Liberalization and Productivity Growth*

This article presents evidence on the positive effect of international trade on productivity growth using industrial level data preceding and following Brazil's trade liberalization in 1988–90. Our data reveal large and widespread productivity improvement across industries after barriers to trade were drastically reduced. Econometric results confirm the association between trade liberalization and productivity growth and show that the impact was indeed substantial: The observed tariff reduction in the period brought a 6% estimated increase in total factor productivity growth rate and a similar impact on labor productivity.     

Do directors perform for pay?

Many corporations reward their outside directors with a modest fee for each board meeting they attend. Using a large panel data set on director attendance behavior in publicly-listed firms for the period 1996–2003, we provide robust evidence that directors are less likely to have attendance problems at board meetings when board meeting fees are higher. This is surprising since meeting fees, on average roughly $1,000, represent an arguably small fraction of the total wealth of a representative director in our sample. Thus, corporate directors appear to perform for even very small financial rewards.     

Does international cross-listing improve the information environment

We investigate whether cross-listing in the U.S. affects the information environment for non-U.S. stocks. Our findings suggest cross-listing has an asymmetric impact on stock price informativeness around the world, as measured by firm-specific stock return variation. Cross-listing improves price informativeness for developed market firms. For firms in emerging markets, however, cross-listing decreases price informativeness. The added analyst coverage associated with cross-listing likely explains the findings in emerging markets, rather than changes in liquidity, ownership, or accounting quality. Our results indicate that the added analyst coverage fosters the production of marketwide information, rather than firm-specific information.     

Propensity to firm creation: empirical research using structural equations

The identification of the entrepreneurs’ characteristics and the knowledge of the entrepreneurial profile of university students have been assuming a growing importance in the development of educational programs directed towards the entrepreneurship and start-up processes. This study aims to identify the factors that most contribute for the intention to start up a business. The research also tries to identify the profile of a potential entrepreneur student concerning several characteristics: personal attributes, family, demographic variables and motivations. Research findings include the idea that entrepreneurship education is the most relevant factor in what concerns the propensity to business creation. On the other side, personal characteristics have an important role in shaping motivation to start-up a business and perceived hurdles have a negative impact in the intention to start-up. The results may be relevant when developing an adequate educational program directed to the entrepreneurship education and start-up processes.     

Portfolio efficiency analysis with SFA: the case of PSI-20 companies

This study aimed to assess the technical efficiency (TE) of individual companies and their respective sectors that are traded on the Portuguese stock market. We accomplished this by combining the internal input variables (e.g., ‘market value and return’) with exogenous variables (e.g., ‘interest income’, ‘depreciation’, ‘cost of goods’, ‘employees’ and ‘net sales’) into a Stochastic Frontier Analysis (SFA) model. The TE of the PSI-20 (Portuguese Stock Index) was estimated using factors that affect efficiency variability. The main advantage of using the SFA approach is its potential to discriminate between measurement error and systematic inefficiencies in the estimation process. The results demonstrated that TE is higher for enterprises in the industrial, construction and distribution sectors, whereas the commercial banking sector has the lowest TE scores. The ‘employees’ and ‘depreciation’ are the variables which most contribute to stock market inefficiency.     

Entrepreneur location decisions across industries

In this paper we analyse whether entrepreneur location decisions differ across industries and identify the factors determining the choice of location between rural and urban environments. Firm location is based on a new taxonomy developed over the influential three dimensions of Hayter’s (1997) approach. The paper uses data from sample of one thousand Portuguese firms. We present a stylized theoretical model to determine how these new five dimensions influence firm’s location and test the model through a logistic regression. Our results show that that the location decisions depend on the sector of activity, type of area (urban vs. rural) and the characteristics of the entrepreneur. We find that companies engaged in knowledge intensive business services prefer to locate in urban areas. From an institutional point of view, firms prefer to locate in rural areas.     

The Recognition of Goodwill and Other Intangible Assets in Business Combinations – The Portuguese Case

In this study, we investigate the magnitude of goodwill recognised in business combinations during the years 2005 to 2009 by the Portuguese companies listed on Euronext Lisbon, and characterise the amount of the other intangible assets recognised separately from goodwill. We also analyse the level of compliance of those companies with the main disclosure requirements of International Financial Reporting Standard (IFRS) 3 – Business Combinations. Our study, which involves the analysis of 197 business combinations, reveals that the amounts of goodwill continue to be highly material, while conversely, the value of identifiable intangible assets in those acquisitions is very low. The results suggest that Portuguese companies do not undertake sufficient efforts to individually identify and disclose intangibles acquired in business combinations. This fact is reinforced by the reduced level of compliance with the disclosures required by IFRS 3, particularly the factors that contribute to the recognition of goodwill. Our findings provide feedback to standard setters in an effort to improve practice in the application of IFRS 3. Moreover, they reinforce their recent concerns regarding the post‐implementation review of business combinations, as well as the ongoing project of the IASB, whose objective is to improve disclosures in existing standards.     

Beyond Single-Factor Affine Term Structure Models

This article proposes a new approach to testing for the hypothesisof a single priced risk factor driving the term structure ofinterest rates. The method does not rely on any parametric specificationof the state variable dynamics or the market price of risk.It simply exploits the constraint imposed by the no-arbitragecondition on instantaneous expected bond returns. In order toachieve our goal, we develop a Kolmogorov-Smirnov test and applyit to data on Treasury bills and bonds for both the United Statesand Spain. We find that the single risk factor hypothesis cannotbe rejected for either dataset.     

Women in the boardroom and their impact on governance and performance

We show that female directors have a significant impact on board inputs and firm outcomes. In a sample of US firms, we find that female directors have better attendance records than male directors, male directors have fewer attendance problems the more gender-diverse the board is, and women are more likely to join monitoring committees. These results suggest that gender-diverse boards allocate more effort to monitoring. Accordingly, we find that chief executive officer turnover is more sensitive to stock performance and directors receive more equity-based compensation in firms with more gender-diverse boards. However, the average effect of gender diversity on firm performance is negative. This negative effect is driven by companies with fewer takeover defenses. Our results suggest that mandating gender quotas for directors can reduce firm value for well-governed firms.
