Interdependencies in the energy–bioenergy–food price systems: A cointegration analysis

The present paper studies the interdependencies between the energy, bioenergy and food prices. We develop a vertically integrated multi-input, multi-output market model with two channels of price transmission: a direct biofuel channel and an indirect input channel. We test the theoretical hypothesis by applying time-series analytical mechanisms to nine major traded agricultural commodity prices, including corn, wheat, rice, sugar, soybeans, cotton, banana, sorghum and tea, along with one weighted average world crude oil price. The data consists of 783 weekly observations extending from January 1994 to December 2008. The empirical findings confirm the theoretical hypothesis that the prices for crude oil and agricultural commodities are interdependent including also commodities not directly used in bioenergy production: an increase in oil price by 1 $/barrel increases the agricultural commodity prices between 0.10 $/tonne and 1.80 $/tonne. Contrary to the theoretical predictions, the indirect input channel of price transmission is found to be small and statistically insignificant.     

Different Manifestations of the Concept of Empowerment: The Politics of Urban Renewal in the United States and the United Kingdom

Over the course of the 1990s the concept of empowerment became firmly established within the vocabulary of urban politics in several different national contexts. This article analyzes the spread of this concept by looking at the politics of urban renewal in the United States and the United Kingdom. It shows that even if (and possibly because) the definition of empowerment remained vague, the turn to empowerment came out of and contributed to a shift in the nature of urban politics and to a reconfiguration of governmental methods, the role of the state and, consequently, to changes in civil society, all of which were associated with a rise to prominence of a neoliberal perspective.     

French Retirement Reforms and Intragenerational Equity in Retirement Duration

As most developed countries, France has gone over the last 20 years through a process of pension system reforms, mainly aiming at increasing the average retirement age, through increasing the required number of contribution years or through postponing legal (minimal and/or normal) ages. Public debates over which lever should be preferred have been paramount in France, with concerns focusing on redistribution issues between high wage high life-expectancy and low-wage low life-expectancy workers. In this paper, we empirically address this issue by simulating the differentiated impacts of the past French reforms on average retirement ages across wage quartiles. Our simulations show that increasing the required duration criterion—as was done by the 1993 and 2003 reforms–have redistributive impact as regards retirement age, while increasing the normal age—as was done by the 2010 reform—has a counter-distributive impact. The redistributive impact on average of the required duration criterion however only holds thanks to the fact that disabled workers—most of them in the lowest wage quartile—are exempted from it. Last, increasing minimal age has ambiguous impacts according to gender: redistributive among women but counter-distributive among men.     

A competing risks analysis of firms’ exit

Firms may exit the market in several ways and each form of exit is likely to be caused by different factors (Schary in RAND J Econ 22:339–353, 1991). This paper explores the determinants of different exit routes. Using a sample of Spanish manufacturing firms for 1990–2000, we estimate a competing risks proportional hazards model to identify the factors leading firms to exit the market through (the mutually precluding events of) liquidation/bankruptcy and acquisition/merger. Our results show the existence of a sharp difference between the determinants of these two exit routes in terms of firm and industry characteristics.     

Internal auditors’ roles: From watchdogs to helpers and protectors of the top manager

The purpose of this paper is to understand the governance roles of internal auditors in public sector organizations. An analysis of 42 in-depth semi-structured interviews conducted with experienced internal auditors working in public administration in Quebec indicates that internal auditors perform two key roles: a protector role, further subdivided into two roles, protective shield and keeper of secrets, and a helper role, also subdivided into two roles, support of organizational performance and guide. The analysis also shows that internal auditors have developed a nuanced conception of independence defined as ‘grey independence’ in order to perform their roles. Internal auditors consider that their primary role is to serve the top manager and the organization and that they must prioritize the top manager at the expense of audit committee members. Therefore, this paper contributes to the literature on internal auditor independence. Overall, the findings suggest that internal auditing is not the governance watchdog expected by the regulatory bodies since this is not the role performed by internal auditors.     

Evaluación de la conversión a café orgánico usando la metodología de opciones reales

Since the deregulation of the coffee market in 1989, price crises are proof of the uncertainty and risk around coffee growers’ income, particularly for small producers who, in the case of Mexico, have taken action such as the conversion of their traditional crops into the organic production system which, besides the ecological priority, allows them to get a higher income than from conventional coffee. In this document we model as real investment options (RIO) the possibility of conversion from one system into the other one also including the feasibility of abandoning this strategic decision.     

Regional growth and unemployment in the medium run: asymmetric cointegrated Okun’s Law for UK regions

This article tests for the presence of a medium-run asymmetric Okun’s Law relationship between regional output and regional unemployment rate in UK regions. The test is performed with a panel data version of the hidden cointegration technique suggested by Granger and Yoon. A novelty of the article is to combine the method of hidden cointegration with a panel data method of removing cross-sectional dependence. The medium-run Okun relationship for regions in the UK appears to confirm results found elsewhere in the literature on countries as a whole, although the coefficients tend to be smaller.     

Exploitation- and exploration-based innovations: The role of knowledge in inter-firm relationships with distributors

Learning capacity is a critical factor for a firm’s innovation and competitiveness. This study explores the issue of how knowledge in inter-firm relationships with distributors influences manufacturers’ exploitation- and exploration-based innovations and performance. The empirical model examines the effect of three different types of knowledge-related issues in inter-firm relationships: (i) the acquisition of substantial knowledge (about products, technology, or markets) from distributors; (ii) the learning about collaborating with each distributor as the relationship evolves; and (iii) the general firm’s knowledge about managing distributors. A model of learning—innovation—performance is developed and tested in a sample of 201 firms in the food and beverages sector. The results reveal that: (i) knowledge about managing distributors promotes continuous learning from them; (ii) learning to collaborate is critical, as it favours knowledge acquisition and both types of innovations (exploitation- and exploration-based); (iii) learning from distributors weakens firms’ tendency to stress one type of innovation strategy over another; and (iv) knowledge in inter-firm relationships with distributors affects performance in a completely mediated way, that is, through innovation. Theoretical and managerial implications of these findings are discussed in the conclusion of the paper.
