Patterns of world wheat trade, 1945–2010: The long hangover from the second food regime

Food regime analysis is concerned with interpreting possibilities and conflicts inherent to the 21st‐century food system in historical terms. This paper summarizes the theoretical discussion of the food regime method, and of the identification of different “food regime periods” throughout modern history. While it is widely accepted that the so‐called “second food regime” has already ended, there is much discussion on whether or not it is possible to talk about a more recent third food regime. This paper traces the evolution of the “wheat complex” over the “second food regime” (1947–1973) and over the next 45 years, and offers an explanation for the evolution of world wheat trade distribution, based on food regime analysis. Certain authors have claimed that the collapse of the WTO Doha round of negotiations may be understood as a “hangover” from the second food regime. Similarly, this paper argues that the increasing wheat dependence of poor and insecure countries over the past 40 years may be considered as a path dependence outcome of a process initiated during the second food regime.     

The effect of new technologies on psychological consequences and risk perceptions of sales agents

The development of new technologies has had important effects on offline distribution channels and, specially, on the psychological effect and risk perceptions that the existence of the online channel may have on the sales agents. Sales agents are fearful that Internet-based competitors will cannibalize their roles in the organization, and might make them outdated and feel insecure about their jobs. This paper estimates the impact of sales agents’ perceptions of service cannibalization on role ambiguity, risk job uncertainty, employee commitment, and employee productivity, considering development of Internet channel, and multi-channel distribution. Data were collected from 497 sales agents who worked at travel agencies located in Spain. Once the model was specified and identified, its parameters were estimated, and authors used various statistics and indices to evaluate overall adaptation of the model. A structural equation modeling was used to examine the posited relationships. This research reinforces the importance of capturing sales agents’s perceptions, especially concerning job insecurity and other outcomes. Specifically, results suggest sales agents’ perceptions of service cannibalization have an effect on role ambiguity and risk and job uncertainty. This study considers the importance of analyzing perceptions of sales agents by travel agency managers to reduce negative consequences on employees, particularly important in view of multi-channel marketing, when a new marketing channel coexists with a traditional sales force.     

Groundwater and ecosystems damages: Questioning the Gisser-Sánchez effect

Gisser and Sánchez (1980a) state the conditions under which welfare gains from policy intervention are negligible in aquifer management, when compared with non-regulation or “free market” outcomes. This is the so-called Gisser-Sánchez effect (GSE), which has been supported by the ensuing literature during recent decades. The GSE requires a number of assumptions, among which is the disregard for aquatic ecosystems linked and dependent on aquifer systems. The depletion of aquifer systems in arid and semiarid regions worldwide is causing acute water scarcity and quality degradation, and leading to extensive ecosystem damages. This study shows that by including environmental damages into the analytical model, results can change substantially. The analysis highlights both theoretically and empirically the importance of policies in groundwater management, as well as the potential role for stakeholders' cooperation. The empirical application deals with two large aquifers in Spain, the Western La Mancha aquifer which is grossly mismanaged, and the Eastern La Mancha aquifer, which is moving towards sustainable management. Western and Eastern La Mancha aquifers illustrate that policies and institutions are essential to avoid the current global aquifer mismanagement.     

Adjustment of Input–Output Tables from Two Initial Matrices

The compilation of the information required to construct survey-based input–output (I–O) tables consumes resources and time to statistical agencies. Consequently, a number of non-survey techniques have been developed in the last decades to estimate I–O tables. These techniques usually depart from observable information on the row and column margins, and then the cells of the matrix are adjusted using as a priori information a matrix from a past period (updating) or an I–O table from the same time period (regionalization). This paper proposes the use of a composite cross-entropy approach that allows for introducing both types of a priori information. The suggested methodology is suitable to be applied only to matrices with semi-positive interior cells and margins. Numerical simulations and an empirical application are carried out, where an I–O table for the Euro Area is estimated with this method and the result is compared with the traditional projection techniques.     

Economic integration and regional convergence: effects of NAFTA on local convergence in Mexico, 1980–2008

Continental integration processes can alter traditional development axes. Paelinck and Polèse´s work in 1999 explains that in the case of Mexico there is a tension between the U.S. border and the rest of the country: Mexico´s integration in the NAFTA should have reduced the U.S. border attraction, extending the growth to territories located between this border and Mexico City. To test this hypothesis, we propose a spatial conditional β-convergence model that uses as regressors both the distances to the U.S. border and to Mexico City, together with other control variables. This model is applied to the period from 1980 to 2008 using GVA at the municipality level. Working with municipal-level data allows to observe convergence patterns across space and identify the effects of location. The time-span studied distinguishes between before and after NAFTA. Estimates based on Mundlak´s approach were obtained for time-invariant regressors. Results show that during the pre-NAFTA period there was a general process of convergence, but it is mainly explained by the faster growth of municipalities located near to the U.S. border. However, post-NAFTA, convergence in municipalities disappeared and the effect of distance to the U.S. border reversed its sign, as predicted in Paelinck and Polèse´s model.     

The effect of futures trading on the distribution of spot index returns: Implications for CVaR in the Spanish market

There is extensive empirical research on the potential destabilizing effects of futures trading activity on spot market volatility. Rather than just focusing on spot volatility, the authors deal with the contemporaneous relationship between futures trading volume and the overall probability distribution of spot market returns. Empirical evidence using intraday data from the Spanish stock index futures market over the period 2000–2002 is provided. Their findings reveal that the density function of spot return conditional to spot volume depends on unexpected futures trading volume.     

Temptation, self-control, and competitive nonlinear pricing

Standard pricing theories consider consumers without temptation. With temptation and costly self-control, consumers dislike choice sets with tempting alternatives. We study firms' strategy against such consumers, using Gul–Pesendorfer preferences and a game where firms compete by offering menus.     

Corporate social responsibility and employee commitment

Effective corporate social responsibility policies are a requirement for today's companies. Policies have not only to be formulated, they also have to be delivered by corporate employees. This paper uses existing research findings to identify two types of factors that may impact on employee motivation and commitment to CSR 'buy-in'. The first of these is contextual: employee attitudes and behaviours will be affected by organizational culture and climate, by whether CSR policies are couched in terms of compliance or in terms of values, and by whether such policies are integrated into business processes or simply an 'add-on' that serves as window-dressing. The second set of factors is perceptual. Motivation and commitment will be affected by the extent to which they can align personal identity and image with that of the organization, by their perceptions of justice and fairness both in general and in terms of how CSR performance is rewarded, and by their impressions concerning the attitude of top management to CSR issues and performance.     

Decomposing income inequality in a backward pre‐industrial economy: Old Castile (Spain) in the middle of the eighteenth century

Research on economic inequality in early modern Europe is complicated by the lack of appropriate data for reconstructing income or wealth distributions. This article presents a study of income inequality in mid‐eighteenth‐century Old Castile (Spain) using the Ensenada Cadastre, a census conducted between 1749 and 1759. The article describes the information provided by this census and then discusses its advantages and disadvantages for reconstructing income profiles and calculating income inequality. This is followed by analysis of a dataset derived from the Cadastre that consists of more than 4,000 observations from Palencia (a province in northern Spain) and contains information on sources of household income, each household head's main occupation, residence location, and other household characteristics. Demographic data from this census is used to weight observations in the sample and thereby minimize selection bias. Findings show that inequality in eighteenth‐century Spain was probably substantial despite its relative backwardness; that the relationship between inequality and per capita income was not clear‐cut and was probably influenced by measurement of the higher incomes; and that although income inequality was largely driven by uneven land distribution, labour income also contributed to overall inequality—especially in urban centres.
