Applied cointegration analysis in the mirror of macroeconomic theory

Cointegration analyses of macroeconomic time series are often not based on fully specified theoretical models. We use a theoretical model to scrutinize common procedures in applied cointegration analysis. Monte Carlo experiments show that (1) some tests of the cointegration vectors do not work well on series generated by an equilibrium business cycle model; (2) cointegration restrictions add little to forecasting; (3) structural VAR models based on weak long-run restrictions seem to work well. The main disadvantages of cointegration analysis without strong links to economic theory are that it makes it hard to estimate and interpret the cointegration vectors.     

Customer satisfaction with service recovery

This commentary is about the article, “Satisfaction with Service Recovery: Perceived Justice and Emotional Responses” (Rio-Lanza, Vázquez-Casielles, and Diaz-Martin, this issue). Never before have so many services been bought, sold, and consumed as they are today. Competition today is fierce. More and more services include a technology component that may limit customer/employee contacts and make services more complex. Retaining customers, therefore, becomes a very relevant issue that makes Rio-Lanza et al.'s research important. Researchers in service management have studied service recovery considerably. This article describes some of the general trends in research about customer satisfaction in connection to service recovery as well as Rio-Lanza et al.'s contribution.     

On the Optimal Exploitation of Terrestrial Animal Species

The paper analyses the social optimal management of terrestrial animal species where land-use costs, non-consumptive benefits of the wild species and nuisance costs, in addition to harvesting profit, are taken into account. When there is harvesting, it is demonstrated that increased profitability of the alternative land-use activities will result in less animals and habitat land in the long-term. It is also shown that the price effect of the harvesting works different compared to the traditional Clark-model of marine resources. Because most terrestrial species represent no harvesting profit and are not harvested, the non-harvesting case is also analysed. Also now will improved profitability in the competing activities of keeping animals be a threat to the wild species as it triggers land-use conversion. Moreover, in absence of harvesting profit, there are no potential counteracting forces due to the existence of harvesting profit.     

Workforce Composition and Innovation: How Diversity in Employees’ Ethnic and Educational Backgrounds Facilitates Firm‐Level Innovativeness

This article studies how workforce composition is related to a firm's success in introducing radical innovations. Previous studies have argued that teams composed of individuals with diverse backgrounds are able to perform more information processing and make deeper use of the information, which is important to accomplish complex tasks. We suggest that this argument can be extended to the level of the aggregate workforce of high‐technology firms. In particular, we argue that ethnic and higher education diversity within the workforce is associated with superior performance in radical innovation. Using a sample of 3,888 Swedish firms, this article demonstrates that having greater workforce diversity in terms of both ethnic background and educational disciplinary background is positively correlated to the share of a firm's turnover generated by radical innovation. Having more external collaborations does, however, seem to reduce the importance of educational background diversity. The impact of ethnic diversity is not affected by external collaboration. These findings hold after using alternative measures of dependent and independent variables, alternative sample sizes, and alternative estimation techniques. The research findings presented in this article would seem to have immediate and important practical implications. They would suggest that companies may pursue recruitment policies inspired by greater ethnic and disciplinary diversity as a way to boost the innovativeness of the organization. From a managerial perspective, it may be concluded that workforce disciplinary diversity could be potentially replaced by more external links, while ethnic diversity could not.     

A Behavior‐Based Approach to the Estimation of Poverty in India

Estimates of poverty in India are crucial inputs for the understanding of world poverty, yet there is much disagreement about the numbers and the legitimacy of methods used to derive them. In this paper, we propose and justify an alternative approach to identify the poor, which uses the proportion of income spent on food. Our estimates have weaker data requirements than official methods, and they compare favorably with several validation tests. Most notably, households around our state poverty lines obtain their calories from similar sources, whereas this is not true of official poverty lines. We also find that rates of self‐reported hunger are higher in states that we classify as poor.     

Opening the Farm Gate to Women? The Gender Gap in U.S. Agriculture

Abstract:

This article provides an empirical analysis of the gender gap for farming in the United States. Using the 2012 U.S. Census of Agriculture we show that farms operated by women earn forty percent less farm income than farms operated by men after controlling for farm and operator characteristics. These findings indicate that farming is one of the most unequal professions in the United States today. Further, we investigate whether three forms of sustainable agriculture improve incomes for women farmers. We find that only farms engaging in Community Supported Agriculture experience a marked decline in the gender income gap.     

ARE IMPACTS OF EARLY INTERVENTIONS IN THE SCANDINAVIAN WELFARE STATE CONSISTENT WITH A HECKMAN CURVE? A META‐ANALYSIS

“Early intervention” has been a mantra in recent debates about human capital investment. Strong theoretical models motivate this focus by predicting that investment in children is most cost‐effective when they are young. The “Heckman curve” summarizes this idea visually (Heckman, 2006). However, hardly any reviews scrutinize this hypothesis empirically in modern welfare states such as those in Scandinavia that already invest heavily during early childhood. Any such review is ideally based on interventions conducted as randomized controlled trials (RCTs), set in the same welfare state, and comparable across ages through cost‐standardized effects. This meta‐analysis assembles cost‐standardized effect estimates from 10 RCTs, including a total of 18 intervention arms and 30,578 participants (aged 1.5–24 years), conducted by the same research center in the Scandinavian welfare state of Denmark. These interventions show significant effects relative to their costs, despite the large baseline investment level. Interventions targeted at younger children tend to produce larger effects, consistent with the Heckman curve. However, variation in the effect size within age groups is as large as it is across age groups. This indicates that both the quality and timing of investments matter and that “early interventions” are not necessarily superior to later interventions.     

Getting a job when times are bad: recruitment practices in Sweden before,during and after the Great Recession

Research on recruitment shows that networks matter and are effective as search channels. The aim of this article is to analyse how recruitment practices varies over time, and specifically, how it has varied before, during, and after the Great Recession 2008–2009. The findings are that recruitment practices change both in the short term, in relation to labour supply, which we can call a cyclical effect, but also in accordance to a long-term, structural effects. Informal recruitment practices, such as recruitment through ‘friends and acquaintances’ and ‘employer made contact’, seem to increase during bad times. In the long run, the recruitment practices ‘direct application’, ‘friends and acquaintances’ and ‘formal private’ increase in relation to recruitment through the Swedish Public Employment Agency (SPEA). A reason for this may be that the labour market in the new knowledge economy demands a heterogenic workforce with high demands on non-cognitive skills and customisation. Here the new network recruitment practices seem to fit in.
