The experience of technological collaborations by MERCOSUR companies

This paper examines some of the experiences in information and knowledge sharing involving MERCOSUR firm. It finds that while technological collaborations by MERCOSUR firms are relatively few, located in low-tech sectors and taking place in an environment of little innovation, they are motivated by the need to ‘fuse’ their own knowledge with that of partner or to improve available information. Modes of governance vary accordingly, with equity or contractual forms being used for new developments and informal agreements for improvements. Govmments and business associations can be important facilitators of technological collaborations. The analysis of technological collaborations suggested that the better prepared a corporation entered an agreement the more successful it was likely to be. It also pointed out that where interactions were intense, well intended and transparent, included personnel exchanges, were properly assessed and involved receptive participants, learning progressed smoothly and partners were satisfied. Benefits of the collaborations included new patentable and non-patentable products new factories, as well as building trust between partners. Premature termination of some collaborations was the result of financia1 limitations unrelated to the success of the collaboration.     

Cross-cultural analysis of the global mindset and the internationalization behavior of small firms

This research analyzes the influence of a global mindset on the internationalization behavior of Norwegian and Portuguese small firms. It specifically sets out to assess the role of global orientation of the entrepreneur and firm perspectives on the global market. Based on a sample of 354 small firms, we used structural equation modeling to conduct our analysis. The results show the differing importance of a range of factors in explaining global mindset in different contexts. The global mindset of Norwegian entrepreneurs conditions their behavior and international experience, while for Portuguese entrepreneurs it affects the cognitive domain and their technical expertise. Global mindset and global orientation have more relevant effects on the internationalization behavior of Norwegian firms than that of Portuguese firms.     

Geometric Asian options: valuation and calibration with stochastic volatility

The scaling properties of two alternative fractal models recently proposed to characterize the dynamics of stock market prices are compared. The former is the Multifractal Model of Asset Return (MMAR) introduced in 1997 by Mandelbrot, Calvet and Fisher in three companion papers. The latter is the multifractional Brownian motion (mBm), defined in 1995 by Péltier and Lévy Véhel as an extension of the very well-known fractional Brownian motion (fBm).

We argue that, when fitted on financial time series, the partition function as well as the scaling function of the mBm, i.e. of a generally non-multifractal process, behave as those of a genuine multifractal process. The analysis, which concerns the daily closing prices of eight major stock indexes, suggests to evaluate prudently the recent findings about the multifractal behaviour in finance and economics.     

Franchisee-based brand equity and performance

This study focuses on the perceptions of franchisees and analyzes the influence of brand equity on franchisee performance. The factors that constitute brand equity are also assessed. Factor analysis was used to generate valid and reliable scales based on a sample of 205 Portuguese franchisee firms, and structural equation modeling methodology was then employed in the analysis. The results show franchisee-based brand equity (FBBE) to be a multivariate factor with strong influence on performance. This study contributes significantly to the literature by showing the perspective of franchisees toward franchising. It also has implications on the adequacy of corporate strategy in achieving performance.     

Portfolio management with tail dependence

Many publications, that treated with Portfolio Management, were devastating for all asset allocation models in the context of portfolios. The elimination of extreme events (asymmetric or tail dependence) during the portfolio construction process can reduce the skills of asset managers to reduce risk through diversification. The copula theory allows us to calculate an alternative to measure the dependence of extreme events in assets through the index lower tail dependence. We check that the strategies with tail dependence overcame Talmud rule, the Markowitz model and the model of Tu and Zhou by simulating 1,000 portfolios with 3, 5, 10 and 20 randomly selected assets from DJIA for the period 03/1990 until 12/2016. We conclude that models of tail dependence and Markowitz had more performance ex-ante than Talmud and the Tu and Zhou model for portfolios with 3, 5, 10 and 20 assets. Tail dependence models overcome Markowitz, in terms of cumulative return, in over 60% of months considered in the analysis. The results indicate that the Talmud rule should be discarded in a context of constructing portfolios with individual stocks ahead strategies with tail dependence.     

From customer motivation to corporate performance. The role of strategic factors and distribution channels of financial service firms

This research analyzes the relationship between strategic factors and distribution channels and the performance of financial service firms, based on the theory of distribution channels and the resource-based view. Using structural equation modeling, the study examines a sample of 252 insurance firms operating in the Iberian Peninsula. The empirical analysis provides conclusive evidence that strategic factors have an influence on the firm’s distribution channels and performance. It also confirms that internal and external determinant factors as well as customer motivation have an influence on strategic factors.     

Socioeconomic modeling: Selecting an appropriate strategy

The simulation strategies of econometrics, system dynamics, and cross-impact analysis have been alternately offered to policymakers over the years. The fact that proponents have tended to glorify their own model's merits and devalue the others has led to confusion and difficulties in making an objective, well-guided selection among them. This paper attempts to cut through the jungle of arguments and counterarguments and to reduce them to their essential elements. The paper then demonstrates that each model presents a unique version of a problem and that these versions are not necessarily competitive. Finally, a guide to modeling selection for policymakers is developed.     

Bank involvement with SMEs: Beyond relationship lending

The “conventional wisdom” in academic and policy circles argues that, while large and foreign banks are generally not interested in serving SMEs, small and niche banks have an advantage because they can overcome SME opaqueness through relationship lending. This paper shows that there is a gap between this view and what banks actually do. Banks perceive SMEs as a core and strategic business and seem well-positioned to expand their links with SMEs. The intensification of bank involvement with SMEs in various emerging markets is neither led by small or niche banks nor highly dependent on relationship lending. Moreover, it has not been derailed by the 2007–2009 crisis. Rather, all types of banks are catering to SMEs and large, multiple-service banks have a comparative advantage in offering a wide range of products and services on a large scale, through the use of new technologies, business models, and risk management systems.     

Effects of the Adoption of IFRS on the Credit Market: Evidence from Brazil

Based on a sample of approximately 6500 credit ratings and 137,000 loan contracts, this paper analyzes the effects of mandatory IFRS adoption on the Brazilian credit market. We find that the IFRS adoption effects were limited to firms displaying improved accounting information quality at the time of transition, lending support to the notion that economic benefits do not necessarily flow from the publication of financial reports in IFRS but, rather, depend on how earnestly firms adopt the recommended disclosure practices.
