The challenge of program evaluation: When increasing program participation decreases the relative well-being of participants

Two goals of food assistance programs are to improve well-being and to increase participation among those in need. Progress in meeting the first goal can be measured by the difference in well-being between participants and eligible non-participants. This gap in well-being though can be affected by progress made toward the second goal of increasing participation rates. In particular, if those with the lowest levels of well-being disproportionately enter the program, the gap can increase. To examine whether this tension between goals exists empirically, we consider the case of the Food Stamp Program and its effect on food insecurity in the United States, using data from the Survey of Income and Program Participation (SIPP). In particular, we use variation in State policies (the change in administrative error rates and the combined value of Temporary Assistance for Needy Families (TANF) and food stamp benefits) to analyze whether increasing participation rates leads to increases in the difference in food insecurity rates. Controlling for other factors, we find evidence of the tension between these two program goals insofar as States with policies which encourage participation have higher differences in the food insecurity rates of participants and non-participants.     

When is Effort Contagious in New Venture Management Teams? Understanding the Contingencies of Social Motivation Theory

Consistent with social motivation theory, prior research on managerial motivation suggests that effort is contagious across management team members. In this study, we draw on belongingness theory to develop a model on important boundary conditions to social motivation theory in the management team context. The model predicts that new venture managers react to their teammates’ higher effort levels by investing higher effort levels themselves primarily when they are confronted with a threat – namely, low venture performance and high environmental hostility – but that effort is less contagious when managers face little threat. We test our model with a sample of 103 new venture managers nested in 51 management teams in a longitudinal setting capturing managerial effort over 26 weeks. While we do not find a direct relationship between teammates’ effort and a new venture manager’s subsequent effort, we find support for the crucial role of threat in triggering the contagion of managerial effort. We discuss the contributions of our study for research on management teams, performance feedback, and entrepreneurial effort in new ventures.     

Regional Economic Impacts of Fusarium Head Blight in Wheat and Barley

Fusarium Head Blight is a fungus affecting wheat and barley in the upper Midwest region of the United States. The purpose of this study is to estimate the direct and secondary regional economic impacts of Fusarium Head Blight infestations from 1998 to 2000. Cumulative direct production and price impacts from Fusarium Head Blight in hard red spring, soft red winter, durum wheat, and barley are estimated at $871 million over the period, with secondary economic losses of $1.8 billion. The total impacts of $2.7 billion were concentrated in North Dakota and Minnesota, which accounted for 55% of total losses over the period.     

Sequential American Exchange Property Options

Property development activities often occur in stages, which are appropriately modeled as sequential American exchange property options, where there are interim expenditures required in order to keep the property development options “alive”. Normally American exchange options require a numerical solution, but herein there is a new closed-form approximate solution, which is computationally efficient and accurate. This method combines repeats of Margrabe European exchange and Geske compound option solutions with tight upper boundaries of either American perpetuities or European exchange options with a high volatility. Illustrations are provided of the sensitivity of the real sequential options and optimal timing to changes in several parameters, which provide a framework for property policy (tax, subsidy and regulatory) guidelines and for property development strategy evaluation. There are several plausible applications of these real option models in commercial and residential property development, within commercial property leases, with regard to switching tenants, and agricultural alternatives.     

A Hotelling–Faustmann Explanation of the Structure of Christmas Tree Prices

We examine the relationship between a tree price and a tree age (height) using a Hotelling–Faustmann type model of optimal plantation management, which accounts for the possibility of replanting and biological growth. The model predictions are tested using the data on Christmas tree prices in North Carolina collected in December 1997. The estimates show that, in general, the rates of change in prices between adjacent age cohorts reflect a competitive equilibrium in the capital market thus supporting the Hotelling–Faustmann paradigm.     

Collectivist values for learning in organizational relationships in China: the role of trust and vertical coordination

Partners must engage in integrative interaction in order to combine diverse expertise and experiences into effective learning. Results from 103 pairs of customer and supplier organizations in China indicate that trust and vertical coordination are useful ways to characterize this integrative interaction and together they promote learning. Structural equation analysis suggests that collectivist but not individualist values are important foundations for integrative interaction between partners that result in learning. These findings were interpreted as reaffirming the value of effective relationships for coordination between partners and suggesting that collectivist values can be a source of effective organizational relationships.     

The new public management and the UK Police Service

This article explores the impact of the introduction of the New Public Management (NPM) within the UK Police Service since the mid-1990s. A specific focus upon individual performance management (one of the central features of NPM) is examined from the perspective of the police sergeant who has primary responsibility for managing performance and ultimately the delivery of policing services within one of the UK's ‘essential’ public services. After a discussion of the literature on individual performance management within the context of the NPM, the article identifies four major research questions relating to: the job role demands of performance management; access to valid and reliable performance management information; the capacity to provide follow-up development and support; and the wider integration of performance management with organization strategy and service objectives. After reporting on interview data collected from role sets in which the sergeant is a focal member, the article concludes with a discussion of the constraints upon effective performance management within the NPM.     

The Surprising Duality of Jugaad: Low Firm Growth and High Inclusive Growth

Western theories on creativity emphasize the importance of access to resources and the generation of innovations as a source of sustainable competitive advantage for firms. However, perhaps the emphasis on slack resources and the firm as the level of analysis may be less appropriate for understanding the benefits of individual creative problem solving in resource-poor environments of the east; focusing solely on the firm is not sufficiently inclusive and may underestimate the benefits of creative problem solving under resource scarcity. Through an inductive interpretive case study of 12 problem solvers in the highly resource-poor environment of rural India, we identified the antecedents, dimensions and duality of outcomes for an Indian cultural source of creative problem solving called jugaad. Jugaad relies on assertive defiance, trial-and-error experiential learning and the recombination of available resources to improvise a frugal quick-fix solution. Our inductive framework provides new insights into the dual outcomes of creative problem solving from an eastern perspective; jugaad is unlikely to be a source of competitive advantage for firm growth but represents a source of enhanced wellbeing for inclusive growth.     

To the Rescue!? Brokering a Rapid,Scaled and Customized Compassionate Response to Suffering after Disaster

Suffering comes in many forms that significantly impact organizations’ operations and performance. As a result, recent research on compassion organizing seeks to explain how efforts to notice, feel, and respond to suffering create organizational (and societal) benefits. Widespread suffering can be generated by natural disasters, which in turn can trigger compassionate organizational responses. In this paper, we build on social capital theory to theorize about how compassionate ventures leverage network relationships to identify and mobilize resources. We also explore how differences in these approaches influence the magnitude, speed, and customization of the response, all of which are theorized indicators of the effectiveness of compassion organizing in alleviating suffering. We use structural equation modelling to test our model and find that compassionate ventures with stronger ties to the local community are more likely to bundle (i.e., stretch) resources, which facilitates a speedy, customized, and large magnitude response. In contrast, those with stronger ties outside the local community are more likely to pursue (i.e., chase) new resources, which results in a large magnitude response, but one that is not associated with speed or customization. We discuss the implications of our findings and make recommendations for future research.     

Conditions for invariance of the multivariate versions of grubbs’ test and bartlett’s test under a general dependency structure

Summary This paper generalizes a result by Stadje (1984) by deriving conditions for which a general dependency structure for multivariate observations, given in Pavur (1987), yields a positive definite covariance structure. This general dependency structure allows the sample covariance matrix to be distributed as a constant times a Wishart random matrix. It is then demonstrated that the maximum squared-radii test and a test for equal population covariance matrices have null distributions which remain unchanged when the new general dependency structure, rather than the usual independence structure, for the vector observations, is assumed. Moreover, under a general dependency structure for which the population covariance matrices are unequal, it is shown that the distribution of the test statistic for testing equal covariance matrices is identical to the distribution of the same test statistic when the population covariance matrices are equal and the observations are independent.
