Labor adjustment costs and complex eigenvalues

Aggregate variables display both persistence and damped oscillations in response to temporary external shocks. The standard real business cycles (RBC) model cannot explain these patterns, because its stable eigenvalues are positive and real. We demonstrate that this model with labor adjustment costs can yield complex eigenvalues. However, numerical experiments suggest that the model cannot display distinguishable damped oscillations of aggregate variables.     

Putting one-to-one marketing to work: Personalization, customization, and choice

The tailoring of a firm’s marketing mix to the individual customer is the essence of one-to-one marketing. In this paper, we distinguish between two forms of one-to-one marketing: personalization and customization. Personalization occurs when the firm decides what marketing mix is suitable for the individual. It is usually based on previously collected customer data. Customization occurs when the customer proactively specifies one or more elements of his or her marketing mix. We summarize key challenges and knowledge gaps in understanding both firm and customer choices in one-to-one markets. We conclude with a summary of research opportunities.     

Africa is on time

We present evidence that the recent African growth renaissance has reached Africa’s poor. Using survey data on African income distributions and national accounts GDP, we estimate income distributions, poverty rates, and inequality indices for African countries for the period 1990–2011. We show that: (1) African poverty is falling rapidly; (2) the African countries for which good inequality data exists are set to reach the Millennium Development Goal (MDG) poverty target on time. The entire continent except for the Democratic Republic of Congo (DRC) will reach the MDG in 2014, one year in advance, and adding the DRC will delay the MDG until 2018; (3) the growth spurt that began in 1995, if anything, decreased African income inequality instead of increasing it; (4) African poverty reduction is remarkably general: it cannot be explained by a large country, or even by a single set of countries possessing some beneficial geographical or historical characteristic. All classes of countries, including those with disadvantageous geography and history, experience reductions in poverty. In particular, poverty fell for both landlocked as well as coastal countries; for mineral-rich as well as mineral-poor countries; for countries with favorable or with unfavorable agriculture; for countries regardless of colonial origin; and for countries with below- or above-median slave exports per capita during the African slave trade.     

Do droughts have long-term effects on water consumption? Evidence from the urban area of Barcelona

This article examines the long-term effects of droughts on water consumption using data of municipalities of the urban area of Barcelona. Two important characteristics of the sample of municipalities are the relatively low water consumption in the pre-drought period and the fact that indoor uses are clearly predominant. Controlling for prices, income and various socio-demographic factors, we find a reduction in water consumption not only during the drought episode but also in subsequent periods. These permanent reductions in water use may be explained by household behavioural changes, technological changes or structural water policy changes.     

An analytical framework for retailer price and advertising decisions for products with temperature-sensitive demand

The demand for weather-sensitive products, such as beverages, ice creams, or chocolate varies with changes in temperature. Yet, retailers lack a framework to adapt the marketing mix elements, such as price and advertising, in line with such changes. We provide a theoretical framework to fill this gap by developing an analytical model to derive the optimal marketing mix when product demand depends on temperature. The model prescribes how price and advertising for different demand characteristics should be set following a temperature change. Integrating the temperature element in the marketing mix offers an original profit-enhancing strategy.     

Transnational Management Influence over Changing Employment Practice: A Case from the Food Industry

The means by which multinational companies (MNCs) develop and diffuse transnational industrial relations practices are the focus of this article. It elaborates different channels through which international management exercises influence over local practice in operations across different countries. Drawing on survey findings, it identifies the kinds of MNC in which the exercise of such transnational influence is most prevalent. The processes involved are investigated through an in-depth study of a European food MNC. This highlights the importance of ‘unobtrusive’ channels of transnational influence operating within a structure which promotes both cooperation and competition between local units.     

Drivers,adoption, and evaluation of sustainability practices in Italian wine SMEs

Based on a survey with 64 small and medium‐sized enterprises (SMEs) in two Italian wine regions, this study aims to (a) identify key drivers and barriers of the adoption of sustainability and (b) compare the adoption and evaluation (use, financial/labor investments, and satisfaction) of sustainability practices in four management domains (marketing, chain, operational, and innovation). Results show that internal drivers were considered to be more important than external drivers. Economic sustainability‐oriented drivers scored significantly lower than drivers related to other dimensions, such as environmental sustainability and heritage. Key barriers refer to labor and investments costs, as well as concerns about greenwashing. Although there are substantial differences in adoption and evaluation of sustainability practices within and between management domains, this study confirms their widespread adoption in wineries. Among users, satisfaction levels outweigh the perceived investments. Except for innovation management practices, financial investments are considered to be lower than labor investments. Positive correlations between use‐satisfaction (within each management domain) and between investments or satisfaction levels (between management domains) further lend support for producers' adoption of multiple practices. At sustainability dimension level, heritage is negatively correlated with the evaluation indicators, indicating that it may act as a potential barrier to some sustainability practices. Segmentation analysis identified a low (30%) and high sustainability clusters (70%), which differ significantly in terms of sustainability perceptions and drivers, adoption, and evaluation of practices, as well as company characteristics. Future research needs to validate the findings on SMEs, compare our measures with more objective evaluation indicators, future adoption rates, and multidimensional sustainability practices.     

Institutional environment and Business Groups' resilience in Brazil

This article combines the institutional theory and political economy approaches to test hypotheses about how transitions in institutional environments affect the performance of Business Groups. Its primary hypothesis is that the different types of political connections established by Business Groups have moderating effects on this relationship. A sample of 1709 observations, from 317 distinct groups operating in Brazil between 2001 and 2009, was used in unobserved effects panel data models, which included the moderating effects of political connections. Our findings suggest that the institutional environment significantly affects Business Groups' performance and that this effect is moderated by political connections, when assessed in terms of the local or federal government as a minor shareholder of the Business Group. The moderating effects of political connections assessed through campaign donations were not conclusive.     

Innovation and Knowledge Transfer in Clustered Interorganizational Networks in Brazil

This article analyzes whether firm innovation is influenced by the transfer of knowledge among cluster firms. To test the hypotheses, we directly estimated the measurement and the structural model parameters where cooperation, workforce mobility, and institutions were defined as manifest indicators of the latent exogenous variable knowledge transfer, modeled as a second-order construct. Firm innovation was defined as a single item endogenous latent variable. We found knowledge transfer to be related to the way firms are managed vis-à-vis (a) the role of institutions as discussion arenas; (b) the adaptability of the workforce; and (c) the indirect cooperation among firms.     

Designing a European unemployment insurance scheme

With disparities in national unemployment rates reaching record levels, the debate on fi scal stabilisers in Europe has gained new momentum. Can a European unemployment insurance scheme help to absorb asymmetric shocks and bring about the desired level of macroeconomic stabilisation? What should such an unemployment benefi t system look like? The contributions to this Forum explore the benefi ts expected from a European unemployment insurance scheme and discuss the diffi culties in establishing such a policy.
