PARADIGM DEPLETION,KNOWLEDGE PRODUCTION AND RESEARCH EFFORT: CONSIDERING THOMAS KUHN'S IDEAS

This paper deals in a Stackelberg differential game with Kuhn (1962) ideas of paradigm depletion and resiliency. Paradigm is considered as potential knowledge, as a stock of ideas that can be harvested to produce science. The results are: (i) paradigm depletion can be optimal, (ii) the optimal editor's shadow price of potential knowledge must be non‐positive, if it is positive, the editor is a keeper of the orthodoxy rather than a scientist, (iii) editor's and/or researcher's impatience is bad for science, and (iv) in equilibrium editor's behavior does not matter for research effort, while only editor's behavior matter for the paradigm.     

An innovation activity model for Very Small Entities in the software sector: an empirical study

Innovation management is a subdiscipline of management that studies the rules that govern the generation, diffusion, adoption of innovation, and relationships between innovation inputs and outputs. A great number of innovative products and services depend on software. In the software industry, many small entities act as subcontractors that develop components that are later integrated into larger industrial systems. However, these small entities do not have the resources needed to support long-term R&D activities and they also lack innovation management models which makes the planning and execution of innovation management difficult. These same small enterprises face similar challenges in the software development process. However, the ISO/IEC 29110 standard provides small enterprises with a clear path in implementing a systematic software development process. The planning and execution of innovation management activities may also benefit from a similar approach. This article describes an innovation activity model suited to the characteristics of small entities whose main stream of revenue is software development. Using the existing literature, standards, and the practical experience of companies with a successful history of developing innovative software-based products, this study identifies the activities and practices that lead to the development of innovative products. Interfaces between innovation management activities, software development processes, and work products are also identified.     

Global mindset and the internationalization of small firms: The importance of the characteristics of entrepreneurs

Despite being a relatively new concept, the importance of the global mindset is already well-documented. So far research has primarily focused on multinational companies and therefore the operationalization of the concept is still a work in progress. Recognizing the importance of entrepreneurs in small companies, yet mindful of the gaps that exist, this paper addresses the factors that constitute the global mindset and their influence on the internationalization of small Portuguese companies. Using information-processing theory through a quantitative, survey-based study and Structural Equation Modeling (SEM), the results show the importance of the characteristics of both entrepreneurs and firms in explaining the global mindset, and confirm the impact they have on internationalization behavior. The entrepreneur??s level of education, their satisfaction with company performance in the domestic market and the potential for growth in the domestic market all affect the global mindset model. The conclusions are useful for entrepreneurs and national authorities aiming to successfully implement internationalization practices, given the role of the global mindset in exploring global business opportunities and in the global success of companies. Replication of the research in different contexts is essential for the wider generalization of the results.     

Does the exchange rate pass-through into prices change when inflation targeting is adopted? The Peruvian case study between 1994 and 2007

This paper analyzes whether the exchange rate pass-through into prices changed when the inflation targeting scheme was adopted in Peru. First, a simple dynamic stochastic general equilibrium model is simulated, which shows that adopting this scheme induces an increase in exchange rate volatility. Furthermore, applying the theory of the currency denomination of international trade, it is demonstrated that increased exchange rate volatility reduces the share of firms that set their prices in foreign currency. Given that the pass-though has a direct relationship with this share, it is shown that adopting inflation targeting generates a pass-through contraction. Second, we empirically test whether the Peruvian Central Bank’s decision to adopt inflation targeting in January 2002 actually had an effect on the pass-through estimating a time-varying vector autoregressive model which allows for an asymmetrical estimation of the pass-through. It provides parameters for both the pre and post inflation targeting regimes based on the assumption that the transition from one regime to the other is smooth. An analysis of the generalized impulse response functions reveals that the decision to adopt inflation targeting significantly decreased the exchange rate pass-throughs into import, producer, and consumer prices. The results are consistent with economic theory and are robust to the specification of parameters of the model.     

MULTIDIMENSIONAL SOCIAL EVALUATION: AN APPLICATION TO THE MEASUREMENT OF HUMAN DEVELOPMENT

This paper deals with the axiomatic derivation of social evaluation indices in a multidimensional context. The resulting evaluation formula is the geometric mean of the egalitarian equivalent values of the different characteristics under consideration. We provide an application to the measurement of human development and compare the results obtained with those corresponding to the standard (additive) index.     

Tests of technical trading strategies in the emerging equity markets of Latin America and Asia

This study examines the potential profit of ten Variable Length Moving Average (VMA) technical trading rules in ten emerging equity markets in Latin America and Asia from January 1982 through April 1995. The average difference in buy − sell returns after trading costs for each rule and country are compared to a buy and hold strategy. Taiwan, Thailand and Mexico emerge as markets where technical trading strategies may be profitable. We find no strong evidence of profitability for the other markets. However, we find that 82 out of the 100 country–trading rule combinations tested in ten emerging markets, disregarding their statistical significance, correctly predict the direction of changes in the return series. These findings may provide investors with important asset allocation information.     

Dynamic learning in behavioral games: A hidden Markov mixture of experts approach

Over the course of a repeated game, players often exhibit learning in selecting their best response. Research in economics and marketing has identified two key types of learning rules: belief and reinforcement. It has been shown that players use either one of these learning rules or a combination of them, as in the Experience-Weighted Attraction (EWA) model. Accounting for such learning may help in understanding and predicting the outcomes of games. In this research, we demonstrate that players not only employ learning rules to determine what actions to choose based on past choices and outcomes, but also change their learning rules over the course of the game. We investigate the degree of state dependence in learning and uncover the latent learning rules and learning paths used by the players. We build a non-homogeneous hidden Markov mixture of experts model which captures shifts between different learning rules over the course of a repeated game. The transition between the learning rule states can be affected by the players?? experiences in the previous round of the game. We empirically validate our model using data from six games that have been previously used in the literature. We demonstrate that one can obtain a richer understanding of how different learning rules impact the observed strategy choices of players by accounting for the latent dynamics in the learning rules. In addition, we show that such an approach can improve our ability to predict observed choices in games.     

Financialization and Portuguese real investment: A supportive or disruptive relationship?

The article makes an empirical analysis of the relationship between financialization and real investment by Portuguese nonfinancial corporations from 1979 to 2013. In theory, while financialization leads to a rise in financial investments by nonfinancial corporations and thus deviates funds from real investment, it also intensifies the pressure for financial payments and therefore restricts the funds available for real investment. We estimate an aggregate investment function including control variables (profitability, debt, cost of capital and output growth) and two measures of financialization (financial receipts and financial payments). The study concludes that there is a long-term investment equation, and finds evidence that the process of financialization has hampered real investment largely as a result of financial payments. The article also finds that profitability and debt are both detrimental to real investment.     

Do central banks affect Tobin's q?

Previous work has documented inflation effects on Tobin's q in the long run. This paper examines whether the FED's different policies and chairmen tenure have an impact on Tobin's q, after a modified stylized AD-AS model shows that central banks affect q. We do find changing responses of q depending on the pre-Volcker and post-Volcker periods.
