A partial occlusion of one or more of the coronary arteries due to atherosclerosis leads to an insufficient supply of blood to the myocardium and as a result to the reduction of its functioning (myocardial ischemia). A total occlusion blocks the blood supply completely, which generally leads to starvation of myocardial tissue (myocardial infarction). Magnetic resonance imaging (MRI) has proven ...

We estimate implied cost of equity capital (re) for a sample of firms from 1984 to 1998 using the Ohlson and Juettner (2000) model that does not make restrictive assumptions about clean surplus and payout policies. We find that re is strongly positively associated with conventional risk factors such as earnings variability, systematic and unsystematic return volatility, and leverage, and is neg...

In this paper I attempt to replicate for Sweden the Corrado, Hulten and Sichel (2006) and Marrano and Haskel (2006) working papers on spending on intangible assets in the US and the UK. Based on their measurement methods the total spending on intangibles in Sweden in 2004 was 277 billion SEK or 10.6 percent of total GDP. Based on total spending it can be estimated that total investment in intan...

We consider a simple general equilibrium model with imperfect competition. Firms are price taker in the input market and compete à la Cournot in some or all of the product markets (their technology displays constant returns to scale). We show that an increase in the number of firms does not always improve welfare. We also provide a characterization in terms of mark-up rates of the sectors for w...

All resources need to be managed to realize opportunities. Isolating the benefits of Information Technology and relating them to the associated costs has proved elusive and threatened emerging opportunities. A change of approach has been advocated to overcome these problems which focuses on the Total Cost of Ownership. Over the past several years, the Total Cost of Ownership has been both haile...

Examining two different changes in retail format, we show that consumers alter their purchase behavior when the retail context changes. In both settings, the change in purchasing behavior is consistent with the effect being driven by an interpersonal interaction between the consumer and the retail clerk. We therefore model the change in format as a “social friction” in which consumers may not p...

Cost-Sharing and Use of Health Services in Italy: Evidence from a Fuzzy Regression Discontinuity Design* We use a Regression Discontinuity Design (RDD) to evaluate the impact of cost-sharing on the use of health services. In the Italian health system, individuals reaching age 65 and earning low incomes are given total exemption from cost-sharing for health services consumption. Since the probab...
