The effects of the Works Progress Administration's anti-malaria programs in Georgia 1932–1947

From 1900 to 1950, malaria rates declined rapidly in the southeast United States. At its peak, malaria infected over 30% of the population. Malaria declined over the period for several reasons: improvements in public infrastructure; development of new insecticides; improvements in agriculture that promoted drainage; increases in incomes; and changes in migration patterns. This paper focuses on public works constructed by the Works Progress Administration (WPA) during the 1930s and subsequent interventions during the 1940s. To estimate the relationship between these malaria programs and malaria rates, I construct a panel of annual county level malaria rates in Georgia from 1932 to 1947. Between 1932 and 1940 the malaria rate in counties that received WPA malaria projects fell from 25.9 deaths per 100,000 to 5.3 deaths per 100,000. The empirical estimates suggest that WPA malaria projects led to 9.1 fewer deaths per 100,000 or roughly 44% of the observed decline in treated counties. Additional public works constructed by the MCWA during World War II, and the introduction of DDT after 1945 completely eliminated malaria in Georgia by 1947.     

A combination of differentiation and consolidation theory and risk-benefit analysis to examine decisions on mastitis prevention

Abstract

Mastitis infections cause severe pain in dairy cows and are the most costly illness to farmers. This study combined differentiation and consolidation (Diff-Con) theory with risk-benefit analysis to explore how risky decisions are perceived and justified after a decision has been taken. More specifically, using survey data from 428 Swedish dairy farmers, their decisions about adopting preventive measures to control mastitis (mastitis control options, MCO) in dairy herds were examined. The analyses included group comparisons with non-parametric rank tests and use of both ordinary least squared regression and seemingly unrelated regression analysis to examine how prior adoption of MCO affects farmers’ attitudes to the MCO. The results showed that MCOs already adopted were rated higher in perceived riskiness (if not implemented) and in expected benefit (for illness prevention) than non-adopted MCOs. Having made the decision to implement a strategy increased the likelihood of that decision being perceived as more beneficial (reducing mastitis) and risky (in terms of disease increase if not implemented), irrespective of the combination of strategies used on the farm, during the post-consolidation stage. No difference in perceived illness prevalence could explain the farmers’ rating of the MCOs. These findings suggest that there may be a path dependency in farmers’ decision-making with respect to MCO. This implies that novel MCOs may have difficulty in achieving wider implementation. These results have implications for the development of strategies to communicate best practices for use of MCOs and for new research on MCOs and farmers’ decision-making.     

Kontrollierte Inflation—ein mißglücktes Experiment?

Summary This study examines how internal economic equilibrium was achieved in Austria after World War II. In contrast to many other Western European countries, the change from a more or less centrally planned economy to a market economy was not accomplished in one step through a currency reform, but through a policy proceeding in several steps which can be regarded as the starting point of the Austrian social partnership after World War II. Through 5 price-wage agreements an attempt was made, with due regard to structural shifts, to adjust the greatly reduced level of production to the level of prices that had remained fixed since the beginning of the war. This article investigates the reasons this attempt eventually failed, and why inflation, which could not be suppressed in the end, was successfully brought under control.     

State competition in higher education: A race to the top,or a race to the bottom?

How does competition affect higher education? This paper explores this question for public and private universities. Theory indicates that competition can push higher education policy in one of two different directions. On the one hand, competition may increase spending. For states, this would occur if states treat higher education as developmental; for private universities this would occur if they view spending as a means to attract students and prestige. On the other hand, competition may decrease spending if states treat higher education spending as redistributive, and competition may decrease spending by private schools if lower spending enhances their ability to attract students with low tuition. To determine which of these perspectives is most valid, we examine higher education policy choices in the 1980s and 1990s. We find that states appear to act as if higher education funding is redistributive while private schools appear to compete more on the basis of tuition than spending. These results demonstrate the important effects competition and governance structure have on higher education.Received: August 2001, Accepted: May 2002, JEL Classification: I2, I22, H72, I3
