Investigating differences among research projects and implications for managers

As research and innovation have become central to the economy, the challenge of managing these activities has taken on greater importance. Studies have focused on the impact of organizational variables on research activities, such as work environment, human resource factors, and managerial practices. But little attention has been paid to the effect of differences among types of research projects. While the notion that differences exist among research projects is acknowledged, particularly in the research & development portfolio literature, there have been relatively few studies into the dimensions by which research projects, and needs of project team members, differ. Further, there is little recognition that these differences translate into the need for different research project management practices. The objective of this paper is to investigate differences among research projects along three dimensions, amount of funding, complexity of project teams, and research orientation. These dimensions are selected because of their central theoretical importance in the organizational literature, as well as posing a number of different challenges for research management. This study looked at 18 research projects at a national laboratory and analyzed the responses of project members to a comprehensive research environment survey conducted in 2001. The results of the analysis indicate that there are significant differences between types of projects along three dimensions and suggest ways that research performance can be improved through management intervention.     

HETEROGENEOUS EFFECTS OF THE ACA MEDICAID EXPANSION ON HOSPITAL FINANCIAL OUTCOMES

This study examines the effect of the Affordable Care Act's Medicaid expansion on hospital financial outcomes. A key innovation relative to prior studies is that we explicitly account for heterogeneity across states in the timing and extent of the expansion as well as across hospital types. We find that Medicaid expansion led to a decrease in uncompensated care expenditures and an increase in average operating margins. The effects were larger in states where the Medicaid expansion led to a greater increase in program eligibility. Operating margins improved most for public hospitals and facilities located in rural areas. (JEL I11, I13, I18)     

Forecasting Foreign Exchange Markets Using Google Trends: Prediction Performance of Competing Models

Abstract

Foreign exchange markets affect a variety of humans and businesses worldwide and there is a wide array of literature aimed at providing more accurate forecasts of their movement. In an attempt to quantify human expectations, Google query search terms related to foreign exchange markets are used to help explain and predict foreign exchange rates between the United States’ dollar and ten other currencies during the time period of January 2004 and August 2018. We find evidence that, while Google Trends can be helpful in prediction, it is necessary to implement some sort of shrinkage or sparsity scheme on the coefficients.     

Share trading activity and the rise of the rentier in the UK before 1920*

Abstract

Using a hand-collected dataset, we examine share trading activity over the period 1882–1920 for the North British and Mercantile Insurance Company, one of the largest UK companies of the time. Our main finding is that the steady flow of rentiers into the shareholding constituency of this company stymied share trading activity. Another important finding is that share trading still occurred during the closure of the stock exchange in 1914, but on a much-reduced scale. We also find that there was a substantial boom in share trading and in insurance stock prices after World War I.     

Immigrant Struggles in New Orleans Post-Katrina

Race relations in New Orleans have often been narrowed to Black and white, especially pre-Katrina. According to the 2000 census, the city was about 67% African American, 27% white, 2% Asian, and 3% “Hispanic.” In a city with a deep history of racial tensions between Black and white, other people of color—and especially recent immigrants—often went unmentioned in discussions of city demographics. The city’s world famous culture—whether in the traditions of Mardi Gras Indians and secondline parades, or in music like jazz and bounce—is also famously rooted in specifically African cultures. Even in media coverage of the city post-Katrina, the story of immigrant experiences has remained mostly invisible. When these stories have been told, they have often fit into the old stereotypes of “model minorities” (as in the case of the Vietnamese recovery) or of low-wage workers stealing jobs (as in the case of news reports on the city’s new Latino population). However, the stories of these other New Orleanians offer an important lens through which to view the overall struggle over the city’s recovery. And the work of grassroots activists from these communities, who strived to not only work for justice for their friends and neighbors, but also to build broad multi-racial alliances, provides an inspiring example for people in other cities who are waging similar fights.     

Immigration and Unemployment: New evidence from Australia and New Zealand

This study uses a new Granger no-causality testing procedure developed by Toda &Yamamoto (1995) to contribute to the debate on immigration and unemployment in Australia and New Zealand. It investigates a possible causal linkage between these variables in a six-variable vector autoregression (VAR) model. The research finds no Granger causality between immigration and unemployment. Instead, it finds evidence of Granger causality running from industrial structural changes, measured by the Stoikov and HDB indices, to unemployment, and from several other economic variables to unemployment.     

The summer people and the natives some effects of tourism in a Vermont vacation village

A village in northern New England was the setting of fieldwork focused on the interaction between the year-round residents of the community (the natives) and their tourist season guests (the summer people). The annual round of activities is geared to the the presence and absence of the summer people; the most highly valued periods of time are the winter season when only natives are residents of the village. As the marketing of the pastoral image of their village to the summer people progresses, the natives face a dilemma. If they are sucscessful in their marketing endeavors, they will prosper financially but, at the same time, they hasten the corruption of their public ideology—the image they hold of their village. The natives are attempting to salvage their future by exploiting the summer people through a “phony-folk culture” and thereby preserving selected aspects of their traditional culture for themselves. The natives' traditional way of life becomes more and more difficult to maintain as it is distorted and consumed by the summer people.     

Technological innovation in tyre manufacture

This paper discusses key factors in starting up local production of radials ahead of most other manufacturers, and how this affected comparative profitability. This led to the build-up of a viable capability for adapting basic overseas innovations to suit local conditions. It will be shown how this capability, in combination with independence in decision-making, compensated the Australian manufacturer relative to resources available to those manufacturers with overseas affiliations.
