COLLECTION AND ANALYSIS OF CROSS-SECTIONAL HOUSEHOLD SURVEY DATA ON RURAL MORBIDITY AND MORTALITY: LESSONS LEARNED FROM INITIAL SURVEYS

In southern Africa, HIV/AIDS is considered to be a critical factor conditioning rural economic development , exacerbating already difficult problems with climatic variability and poverty. In their efforts to use household surveys to obtain information on rural adult mortality and morbidity and their effects on rural household livelihoods, Michigan State University researchers and their local collaborators in the Ministries of Agriculture of Rwanda (MINAGRI) and Mozambique (MADER), have learned various lessons. Using household surveys to estimate the impact on the households requires careful attention to detail as well as skilled use of econometric tools. The difficult modeling issues involved in such estimation is not be discussed in this paper. Rather, we focus on the basic data collection required and the formulation of effective survey questions. Based on the survey instruments used in these two countries, suggestions are made to improve the ability of researchers to estimate mortality rates, evaluate changes in demographic composition of the households, and elicit information from households regarding incidence of illness and death, their effects on household livelihoods, and the households' response strategies. This paper provides recommendations for future survey instruments to improve the knowledge base so critical for the design of interventions.Labor and Human Capital,

Real Wage Trends, 1979 to 2017

[Excerpt] The focus of this report is on wage rates and changes at selected wage percentiles, with some attention given to the potential influence of educational attainment and the occupational distribution of worker groups on wage patterns. Other factors are likely to contribute to wage trends over the 1979 to 2017 period as well, including changes in the supply and demand for workers, labor market institutions, workplace organization and practices, and macroeconomic trends. This report provides an overview of how these broad forces are thought to interact with wage determination, but it does not attempt to measure their contribution to wage patterns over the last four decades. For example, changes over time in the supply and demand for workers with different skill sets (e.g., as driven by technological change and new international trade patterns) is likely to affect wage growth. A declining real minimum wage and decreasing unionization rates may lead to slower wage growth for workers more reliant on these institutions to provide wage protection, whereas changes in pay setting practices in certain high pay occupations, the emergence of superstar earners (e.g., in sports and entertainment), and skill biased technological changes may have improved wage growth for some workers at the top of the wage distribution. Macroeconomic factors, business cycles, and other national economic trends affect the overall demand for workers, with consequences for aggregate wage growth, and may affect employers’ production decisions (e.g., production technology and where to produce) with implications for the distribution of wage income. These factors are briefly discussed at the end of the report

A Simple Approach to Constructing Quasi-Sudoku-based Sliced Space-Filling Designs

Sliced Sudoku-based space-filling designs and, more generally, quasi-sliced orthogonal array-based space-filling designs are useful experimental designs in several contexts, including computer experiments with categorical in addition to quantitative inputs and cross-validation. Here, we provide a straightforward construction of doubly orthogonal quasi-Sudoku Latin squares which can be used to generate sliced space-filling designs which achieve uniformity in one and two-dimensional projections for both the full design and each slice. A construction of quasi-sliced orthogonal arrays based on these constructed doubly orthogonal quasi-Sudoku Latin squares is also provided and can, in turn, be used to generate sliced space-filling designs which achieve uniformity in one and two-dimensional projections for the full design and and uniformity in two-dimensional projections for each slice. These constructions are very practical to implement and yield a spectrum of design sizes and numbers of factors not currently broadly available.Comment: 15 pages, 9 figure

Measuring the Impact of Public and Private Assets on Household Crop Income in Rural Mozambique, 2002-2005

This brief summarizes detailed analysis of the determinants of household crop income in rural Mozambique from 2002 to 2005. Increased crop income is associated with increases in household land area, use of animal traction, crop diversification into tobacco or cotton, access to market price information, and access to extension agents (for tobacco/cotton growers). Decreases in crop income are associated with drought. Results demonstrate that there are both public and private investments that can enhance farmers’ ability to increase crop income and avoid losses. Priority investments include: development and dissemination of drought-resistant varieties for maize and cassava, conservation farming, animal traction, market information, access to high-value crops and small-scale irrigation.agriculture, africa, mozambique, food security, assets, household, rural, Agricultural and Food Policy, Community/Rural/Urban Development, Consumer/Household Economics, Food Security and Poverty, International Development, q12,

Cramming: The Effects of School Accountability on College-Bound Students

This paper is the first to explore the effects of school accountability systems on high-achieving students' long-term performance. Using exceptional data from a large highly-selective state university, we relate school accountability pressure in high school to a student's university-level grades and study habits. We exploit a change in the state's accountability system in 1999 that led to some schools becoming newlythreatened by accountability pressure and others becoming newly-unthreatened to identify the effects of accountability pressure. We find that an accountability system based on a low-level test of basic skills apparently led to generally reduced performance by high-achieving students, while an accountability system based on a more challenging criterion-referenced exam apparently led to improved performance in college on mathematics and other technical subjects. Both types of systems are associated with increased "cramming" by students in college. The results indicate that the nature of an accountability system can influence its effectiveness.

What Does the Gig Economy Mean for Workers?

[Excerpt] Technological advancement and the proliferation of the smartphone have reshaped the commercial landscape, providing consumers new ways to access the retail marketplace. On-demand companies are one such innovation, and underpinning on-demand commerce is the gig economy, the collection of markets that match service providers to consumers of on-demand services on a gig (or job) basis. Flagship on-demand companies such as Uber (driver services) and Handy (home cleaners and household services) have garnered significant media attention both for their market success and recent legal challenges, particularly concerning the classification of gig workers. Broader questions about the pros and cons of the gig economy have emerged as on-demand markets grow and the gig economy expands into new sectors. By some accounts, workers’ willingness to participate in the gig economy provides evidence that gig work is a beneficial arrangement. Indeed, gig jobs may yield benefits relative to traditional employment in terms of the ease of finding employment and greater flexibility to choose jobs and hours. The gig economy may facilitate bridge employment (e.g., temporary employment between career jobs or between full-time work and retirement) or provide opportunities to generate income when circumstances do not accommodate traditional full-time, full-year employment. At the same time, however, the potential lack of labor protections for gig workers and the precarious nature of gig work have been met with some concern. The nationwide reach of gig work and its potential to impact large groups of workers, and their livelihoods, have attracted the attention of some Members of Congress. These Members have raised questions about the size and composition of the gig workforce, the proper classification of gig workers (i.e., as employees or independent contractors), the potential for gig work to create work opportunities for unemployed or underemployed workers, and implications of gig work for worker protections and access to traditional employment-based benefits. In support of these policy considerations, this report provides an overview of the gig economy and identifies legal and policy questions relevant to its workforce

Hydrostratigraphy and allostratigraphy of the Cenozoic alluvium in the northwestern part of Las Vegas Valley, Clark County, Nevada

This investigation was conducted to determine the location, nature, and boundaries of the most permeable unit within the alluvial aquifer material in Las Vegas Valley. It was prompted by declines in specific capacity of about 90% at the Las Vegas Valley Water District\u27s West Central Well Field. It was hypothesized that the decline in specific capacity resulted from dewatering of the most permeable interval of the alluvium. Lithologic descriptions from wells and aquifer test information were analyzed for geologic and hydrogeologic variability. New information, in the form of detailed unpublished lithologic and hydrologic information, was available from twenty water wells drilled between 1989 and 1994; The geology was defined using allostratigraphic units; Aquifer test and lithologic information was used to define the boundaries of units of differing permeability within the subsurface. These units of differing permeability are the six (6) hydrostratigraphic units introduced in this investigation. The most permeable hydrostratigraphic unit is a distinct 20 to 90 m thick horizon, lying generally above 230 m below land surface. When the production wells were first installed at the West Central Well Field in the 1960\u27s, most of the permeable unit was saturated. In 1993 the potentiometric surface was at or below the bottom of this hydrostratigraphic unit. (Abstract shortened by UMI.)
