A 20-plane wire chamber spectrometer utilizing capacitors as memory elements and suitable for operation in a magnetic field is described. The (parallel) wire planes are separated by N 1 cm. The active areas of the chambers range in size from 120 X I20 cm2 t0 200 x 240 cm2, The wire separation is 1 mm. Each readout wire is connected to a separate capacitor resulting in a 30 K-bit memory for the ...

Over-Education in Multilingual Economies: Evidence from Catalonia Catalonia’s economy is characterized by linguistic diversity and provides a unique opportunity to measure the incidence of language proficiency on over-education, particularly, whether individuals with deficient language skills tend to acquire more formal skills or, on the contrary, become discouraged to attend school. Descriptiv...

In every developed country, the economic transition from pre-industrial stagnation to modern growth was accompanied by a demographic transition from high to low fertility. Even though the overall pattern is repeated, there are large cross-country variations in the timing and speed of the demographic transition. What accounts for falling fertility during the transition to growth? To answer this ...

The Short-Term Effectiveness of a Remedial Mathematics Course: Evidence from a UK University Whilst in the US there is a growing debate about the effectiveness of remedial university courses, this issue is less questioned in the UK. Using a regression discontinuity approach and data from a large School of a post-1992 UK university, we estimate the effect of remediation on student outcomes. We f...

SBTC is a powerful mechanism in explaining the increasing gap between educated and uneducated wages. However, SBTC cannot mimic the US within-group wage inequality. This paper provides an explanation for the observed intra-college group inequality by showing that the top decile earners’ significant wage growth is underpinned by the link between ex ante ability, math-heavy college majors and hig...

Everybody Needs Good Neighbours? Evidence from Students’ Outcomes in England We estimate the effect of neighbours’ characteristics and prior achievements on teenage students’ educational and behavioural outcomes using census data on several cohorts of secondary school students in England. Our research design is based on changes in neighbourhood composition caused explicitly by residential migra...

An important piece of the major fiscal and structural reforms undertaken in Argentina in the early 1990’s was the decentralization of education services from the federal government to the provincial governments. The theoretical literature does not find absolute superiority of centralization or decentralization in the provision of public services. We evaluate empirically the effect of the decent...

Data from the National Longitudinal Survey of Youth (NLSY) are analyzed to examine whether adolescents living in low-income urban areas have less accurate information about labor market institutions than teens in more affluent communities, and whether information influences educational attainment. All adolescents seem to implicitly underestimate the educational requirements of their occupationa...

The purpose of this paper is to quantify the efficiency with which Australian universities utilise their teaching resources. The study estimates the cost efficiency of 36 universities over the period 1995-2002 using stochastic frontier analysis. The present study differs from previous cost and efficiency studies of Australian universities in two respects. First, it employs stochastic frontier a...
