Financial hedging with derivatives and its impact on the Colombian market value for listed companies

The financial theory (Modigliani & Miller, 1958) presents risk management as a matter without importance in companies, given that the shareholders themselves managed their hedges, diversifying their portfolios. However, subsequent studies dispute said premise and present evidence that business financial hedging improves performance and increases the value of the same (Ahmed, Azevedo, & Guney, 2014; Allayannis & Weston, 2001; Kapitsinas, 2008). The efficient market risk management is supported in the financial derivatives, and demands strategic and efficient administrators in hedges that add value, especially in the face of clashes and macroeconomic and financial imbalances. The empirical evidence analyzes the behavior of the Q-Tobin as an indicator of the effect of the hedge strategies for the exchange rate associated to the market value. The aim of this work is to find evidence in Colombia on the effect of the use of derivatives in the market value of the company. Its added value lies in the analysis that is done by economic sectors, identified by ISIC codes and grouped into five (5) macro sectors (Agriculture and livestock, Commercial, Industrial or Manufacture, Services, and Construction). The methodology used includes the estimation of several regression models in data panels, using a Pooled regression model with fixed and random effect estimators through the maximum likelihood estimator. In general, a statistical and financially significant premium for hedges was found for companies exposed to exchange rate risks that use derivatives of a 6.3% average on the market value. Additionally, mixed results were found in relation to the variables analyzed in the model.     

User cooperation effects on firm's innovation outputs

We analyzed the effects of R&D cooperation with users and the intensity/continuity of such cooperation on firms' innovation output—whether radical or incremental. We also examined the moderating effect of firm size on these relationships. Results show that cooperation with users favours the development of both radical and incremental product innovations. In addition, we found that the higher the intensity/continuity of the relationship with users, the more likely radical innovations are to develop when compared with incremental innovations. We note that the positive effect of cooperation on the development of innovation is especially significant for small firms. Copyright © 2015 ASAC. Published by John Wiley & Sons, Ltd.

Using a functional approach to test trending volatility in the price of Mexican and international agricultural products

In this article, we extend the traditional GARCH(1,1) model by including a functional trend term in the conditional volatility of a time series. We derive the main properties of the model and apply it to all agricultural commodities in the Mexican CPI basket, as well as to the international prices of maize, wheat, swine, poultry, and beef products for three different time periods that implied changes in price regulations and behavior: before the North American Free Trade Agreement (NAFTA; 1987–1993), post‐NAFTA (1994–2005), and commodity supercycle (2006–2014). The proposed model seems to adequately fit the volatility process and, according to heteroscedasticity tests, also outperforms the ARCH(1) and GARCH(1,1) models, some of the most popular approaches used in the literature to analyze price volatility. Our results show that, consistent with anecdotal evidence, price volatility trends increased from the period 1987–1993 to 1994–2005. From 1994–2005 to 2006–2014, trends decreased but the persistence of volatility increased for most products, especially for international commodities. In addition, we identify some agricultural products such as avocado, beans, and chicken that, due to their increasing price volatility trends in the 2006–2014 period, may present a risk for food inflation in the short run.     

Why So Small? Explaining the Size of Firms in Latin America

On average, Latin American firms are small with respect to world patterns, both in terms of the quantity of assets they control and the amount of employment they generate. We examine data on firm size from developed and developing countries around the world to assess the influence of demand, supply and institutional factors on the size of the largest firms in each country. We find that, besides the size of the economy and the level of income per capita, the key determinants of the size of firms are trade openness, stock market capitalisation and physical infrastructure. Our simulations suggest that if the gaps with respect to the best Latin American performer were closed in each of these three areas, firm size in the countries of the region would – on average – reach world patterns.     

Institutional density and public policies in two cases of geographical indications from Mexico and Spain

This study analyses the role of private and/or public institutions on achieving success in projects aiming to obtain certification labels for local food products. This analysis is performed through comparative framework provided by 2 specific study cases; 1 from Mexico, based on the production of a type of traditional spicy pork sausage, or chorizo, and another from Spain, on the production of Iberian ham. A mixed methodology has been used to perform an in‐depth analysis of socio‐political contexts by distinguishing the divergent institutional frameworks of both cases. The study will contribute to connecting the results of these initiatives to the institutional density in which both proposals are originated and are implemented. From there, the text explores the reasons for success, stagnation, and/or failure of these actions. These empirical data constitute an important contribution to the analysis of geographical indications and diverse sociological universes supporting the differentiation of agrifood quality certification.     

James Andreoni and the quest for others in our utility functions

Over the past 30 years, James Andreoni has produced a body of work like few others in public economics. Motivated by a personal need to understand the determinants of prosocial behavior, and by offering a rare blend of insights from formal theory, controlled experiments, and field data, Andreoni has succeeded in elucidating the broader relevance of prosocial motives and their far‐reaching economic implications. This article offers an overview of his work on prosociality, highlighting some of his seminal contributions and placing them in a historical context. We argue that James Andreoni has had a unique role in the quest to ensure that others have a place in our utility functions.     

Social capital,internationalization and absorptive capacity: The electronics and ICT cluster of the Basque Country

This article analyses the case of a successful young high technology cluster in an old industrialized European region, the electronics and information and communications technology cluster in the Basque Country (Spain). Based on the findings of this case study, we propose that social capital and internationalization play an important role in increasing the absorptive capacity of clusters (thus, the capacity of a cluster to absorb, diffuse and creatively exploit extra-cluster knowledge), and hence, in sustaining their growth and dynamism. Absorptive capacity depends on the capacity of firms to establish intra- and extra-cluster knowledge linkages. We put forward in this article the fact that social capital fosters intra-cluster knowledge linkages, and cluster's internationalization the extra-cluster knowledge ones. Therefore, social capital and internationalization are key elements to increase the absorptive capacity of a cluster and its growth. Given the accumulative, path- and place-dependent nature of social capital and knowledge creation and accumulation, we employed a largely qualitative and historical analysis, combining statistical and qualitative cluster data and interviews with key actors.
