Targeting and distribution in complex emergencies: Participatory management of humanitarian food assistance

The extensive literature on community participation in the targeting and management of humanitarian food assistance suggests that participatory approaches work best in slow-onset emergencies with no conflict or displacement. Yet the policies of many agencies—and compliance with Sphere minimum standards—require that the recipient community participate in decisions about the assistance they receive including targeting, regardless of the causes of the emergency. This paper analyzes current practice in the targeting and management of humanitarian food assistance in complex emergencies, the constraints to recipient communities’ participation, and the possibilities for participatory approaches to improve targeting.     

Comparing different explanations of the volatility trend

We analyze the puzzling behavior of the volatility of individual stock returns over the past few decades. The literature has provided many different explanations to the trend in volatility and this paper tests the viability of the different explanations. Virtually all current theoretical arguments that are provided for the trend in the average level of volatility over time lend themselves to explanations about the difference in volatility levels between firms in the cross-section. We therefore focus separately on the cross-sectional and time-series explanatory power of the different proxies. We fail to find a proxy that is able to explain both dimensions well. In particular, we find that Cao et al. [Cao, C., Simin, T.T., Zhao, J., 2008. Can growth options explain the trend in idiosyncratic risk? Review of Financial Studies 21, 2599-2633] market-to-book ratio tracks average volatility levels well, but has no cross-sectional explanatory power. On the other hand, the low-price proxy suggested by Brandt et al. [Brandt, M.W., Brav, A., Graham, J.R., Kumar, A., 2010. The idiosyncratic volatility puzzle: time trend or speculative episodes. Review of Financial Studies 23, 863-899] has much cross-sectional explanatory power, but has virtually no time-series explanatory power. We also find that the different proxies do not explain the trend in volatility in the period prior to 1995 (R-squared of virtually zero), but explain rather well the trend in volatility at the turn of the Millennium (1995-2005).     

Results of a cross-national structured cognitive interviewing protocol to test measures of disability

This paper describes the Washington Group project to test a short battery of disability questions developed for national censuses. The study used an unusually structured cognitive test protocol and was administered to a total of 1,290 respondents selected from convenience samples in fifteen countries in Central and South America, Asia and Africa. The test protocol consisted of the six core disability questions followed by questions designed to illustrate: (1) whether core questions were administered with relative ease; (2) how core questions were interpreted by respondents; (3) the factors considered by respondents when forming answers to core questions; and (4) the degree of consistency between responses to core questions and a set of more detailed functioning questions. Additionally, demographic and general health sections allowed for an examination of comparability, specifically, whether test questions performed consistently across all respondents, or if nationality, education, gender or socio-economic status impacted the ways in which respondents interpreted or considered each core question.     

Roadmapping for technology push and partnership: A contribution for open innovation environments

There are several tools in the literature that support innovation in organizations. Some of the most cited are the so-called technology roadmapping methods, also known as TRM. However, these methods are designed primarily for organizations that adopt the market pull strategy of technology-product integration. Organizations that adopt the technology push integration strategy are neglected in the literature. Furthermore, with the advent of open innovation, it is possible to note the need to consider the adoption of partnerships in the innovation process. Thus, this study proposes a method of technology roadmapping, identified as method for technology push (MTP), applicable to organizations that adopt the technology push integration strategy, such as SMEs and independent research centers in an open-innovation environment. The method was developed through action-research and was assessed from two analytical standpoints: externally, via a specific literature review on its theoretical contributions, and internally, through the analysis of potential users' perceptions on the feasibility of applying MTP. The results indicate both the unique character of the method and its perceived implementation feasibility. Future research is suggested in order to validate the method in different types of organizations     

Deforestation dynamics and policy changes in Bolivia's post-neoliberal era

This work compares the effects of neoliberal and post-neoliberal land-use policies on forest cover along the Corredor Bioceánico of southeastern Bolivia to determine if rates of agriculturally driven forest clearance have changed since the Morales’ administration came to office in 2005. Satellite image analysis, supported by semi-structured interviews with farmers and representatives of key institutions, shows that deforestation for commercial agriculture in Santa Cruz continues and has increased in certain “hotspots”. Previous research has shown that the environmental effects of neoliberalism on forest cover are varied, but more broadly, reduced state intervention has meant less environmental regulation and greater deforestation, while strong government is better able to curtail deforestation. Although neoliberal policies triggered an unprecedented level of forest clearing in Bolivia, rates have generally continued to increase and can be indirectly linked to the administration's new agrarian reform and pro-environmental regulations. This trend is counterintuitive and stems from unanticipated responses such as deforestation through fire to prove productive use under the reform's socio-economic function requirements. Given increased regulation and enforcement of forest clearing and burning under Morales, in contrast to the neoliberal era, our analyses suggest that rates will continue to increase under the current political climate, which has further polarized the opposition in Santa Cruz.     

The Economic Impact of Marena’s Investments on Sustainable Agricultural Systems in Honduras

This study examines the economic impact of sustainable agricultural production systems in Central America. In particular, we investigate the impact of investments promoted by the MARENA Programme in Honduras on the total value of agricultural production (TVAP) of its beneficiaries. Propensity Score Matching techniques along with the Difference‐in‐Differences framework are used to mitigate biases stemming from differences in observed as well as unobserved (time‐invariant) characteristics between beneficiaries and a control group. The econometric estimates suggest that MARENA has had a positive and significant effect on the TVAP of beneficiaries. In addition, the analysis shows that, under alternative scenarios, MARENA yielded higher than expected internal rates of return. The results of this study shed light on the response of small‐scale hillside farmers to economic incentives and lend support to the role of natural resource management projects in Central America as a tool to increase household income while also promoting the conservation of natural resources.     

Institutionalist Labor Market Theory and the Veblenian Dichotomy

This paper contributes to an institutional theory of crime. More specifically, it focuses on the problem of the mafia and the infiltration of legitimate businesses. In legal markets, the mafia resorts to artificial scarcity as a functioning principle. Although scarcity and its consequences for market economies are key aspects of mainstream economics, they have been insufficiently analyzed because the emphasis is only on "natural" scarcity. The mafia phenomenon reveals that scarcity can also be institutionally created. This type of scarcity encourages the process of market collectivization and empowers those generating it. The mafia's legal activities establish a system of "waiting lines" and monitored access to goods. Instead of being merely coercive and openly violent, the mafia builds a new lasting order, producing its own rules, and even breeding social legitimacy.     

Analysis of non-stationary dynamics in the financial system

Novel data-driven analyses, appropriate for detecting economic instability in non-stationary time series, are developed using functional principal component analysis (fPCA) and Synchrosqueezing. fPCA is applied in a new way, aggregating multiple financial time series to identify periods of macroeconomic instability. Synchrosqueezing, a technique which generates a time-series’ time-dependent spectral decomposition, is modified to develop a new quantitative measure of local dynamical changes and structural breaks. The merit of this integrated technique is demonstrated by analyzing financial data from 1986 to 2012 that includes equity indices, securities and commodities, and foreign exchange. Both procedures successfully detect key historic periods of instability. Moreover, the results reveal distinctions between periods of long-term gradual change in addition to structural breaks. These tools offer new insights into the analysis of financial instability.
