OBJECTIVES We aimed to estimate the annual socioeconomic burden of coronary heart disease (CHD) in Korea in 2005, using the National Health Insurance (NHI) claims data. METHODS A prevalence-based, top-down, cost-of-treatment method was used to assess the direct and indirect costs of CHD (International Classification of Diseases, 10th revision codes of I20-I25), angina pectoris (I20), and myoc...

We use the recent introduction of tuition fees at public universities in seven of the sixteen German states to identify the effects of tuition fees on university enrollment of first-year students at German public universities. Our study differs from previous research in two important ways. Firstly, we take into account the location of universities and include a spatial variable, which measures ...

WbdD is a bifunctional kinase/methyltransferase that is responsible for regulation of lipopolysaccharide O antigen polysaccharide chain length in Escherichia coli serotype O9a. Solving the crystal structure of this protein proved to be a challenge because the available crystals belonging to space group I23 only diffracted to low resolution (>95% of the crystals diffracted to resolution lower th...

One goal of state merit-based financial aid programs is to increase the stock of college-educated labor in the state by retaining college-educated persons in the state after college. However, there has been surprisingly little research on whether state merit aid programs are effective at this goal. This paper investigates the effect of state merit aid programs on the post-college location of 24...

We study the mental health of graduate students at eight top-ranked economics PhD programs in United States using clinically validated surveys. find that 24.8 percent experience moderate or severe symptoms depression anxiety—more than two times population average. Though our response rate was 45.1 and sample selection concerns exist, conservative lower bounds nonetheless suggest higher prevalen...

The increasing use of aptitude tests as part of the admissions processes at elite English universities potentially has significant implications for fair access to these institutions. I attempt to isolate the impact of the introduction of one such test on the proportion of successful applicants by school type (as a proxy for socioeconomic status) and by gender using a difference in differences a...

I present a revealed preference ranking of school quality. This is helpful to pin down between two or more schools the one that attracts high ability students at the lowest additional cost of quality. Available school rankings don’t capture the heterogenous effects that an increase in school quality has on the choices of students with different characteristics. To do so, I obtain the ranking by...

Who Performs Better under Time Pressure? Results from a Field Experiment We investigate whether and how time pressure affects performance. We conducted a field experiment in which students from an Italian University are proposed to choose between two exam schemes: a standard scheme without time pressure and an alternative scheme consisting of two written intermediate tests, one of which to be t...

In 2010, ischemic heart disease was the leading cause of disability-adjusted life-years (DALYs) worldwide. More specially, the prevalence of acute myocardial infarctions (AMI) is increasing in the aged population as mortality decreases; South Korea is no exception. This study aims to examine the economic burden of AMI in the Korean population between 2007 and 2012. AMI-related costs were assess...

Declining college matriculation rates, the unrelenting rise in net tuition costs and the questionable quality of some accredited degree programs has led to heightened public scrutiny of the higher education sector. There is current political pressure on institutions to increase access in a manner that does not require a large and growing student debt burden. Selective and top ranked schools wit...
