Network Layout:
We distinguish three layouts, which are defined by the number of buildings B ∈ {1, 2, 6} and the number of floors per building F ∈ {1, 3, 6}. Each floor has a certain number of rooms (locations) R ∈ {6, 7, . . . , 10} drawn from a discrete uniform distribution. One of the buildings contains the therapy centers, which has a capacity between 2 and 6. The capacity at the ward rooms is always unlimited since patients cannot be scheduled to other patients’ ward room. The travel time between two buildings is drawn at random from the set {10, 15, 20} minutes. The travel time between neighboring floors is assumed to be 5 minutes, and the travel time between two rooms on the same floor is either 5 or 10 minutes.
Demand Scenarios:
We distinguish six demand scenarios having 20, 40, 60, 80, 100 and 120 treatments. A 10% probability exists that the patient is an outpatient, i.e. he/she can only be treated in a therapy center and the start time for the treatment is fixed. Ten percent of the patients are bedridden, i.e. the patient must not be moved and can only be treated in his/her room at the ward. However, these latter patients have a rather wide start time window of 90 minutes. The remaining patients are regular inpatients, of which 50% have location flexibility, i.e. the patient can be treated at the ward and in the therapy centers; however, a preference for one location exists, generally the ward room. The start time window length of these patients varies between 30 and 45 minutes. Thirty percent of the patients receive multiple treatments (2 or 3) in one day. Every treatment job has a duration of 10 to 45 minutes and requires a certain skill level. We assume hierarchical skills ranging from 1 (lowest) to 3 (highest). The probabilities that a job requires a certain skill are 60%, 30% and 10% for skills 1, 2 and 3, respectively.
Vehicles:
We use a heterogeneous fleet, since therapists differ in their skills as well as their shift patterns. The skills are the same as for the jobs; however, the probabilities of having skill 1, 2 and 3 are 10%, 60% and 30%. A therapist has a regular (long) shift with 80% probability. Otherwise, the therapist has a short shift with 50% probability of being a morning or evening shift. We assume that therapists start and end their shifts in the break room (depot), which is 5 minutes away from the therapy centers
Welfare Implications of the Design of a Currency Union in Case of Member Countries of Different Sizes and Output Persistence
No full textIn the study, the relevance of several optimum-currency-area (OCA) criteria is formally worked out in a welfare approach. The optimum monetary-policy rules of the supranational central bank are derived within the Barro-Gordon framework, and consideration is given to how the welfare of the member countries of a currency union is affected by symmetric and asymmetric national output shocks. The welfare implications are deduced both analytically and with the use of simulations. In a twocountry framework, the countries are allowed to differ in size, and different degrees of labour mobility are addressed. Also the issue of output persistence is taken up. The central-bank council may consist of a central-bank board and of a group of national central-bank presidents, where the national presidents are assumed to focus on their home economies. It is shown that relatively small member countries favour a situation where the group of national central bank presidents is in a strong position while large countries prefer decisions to be taken by the central-bank board. The preferences are the less strong the higher the degree of labour mobility. With output persistence, labour migration also moderates the disadvantages of the decisions taken by a central-bank board for a relatively small country. Furthermore, for output persistence in conjuncture with labour migration, monetary policy by a small country within the group of national presidents may negatively affect its future welfare. Besides, differences in the national monetary transmission processes as well as divergent national inflation and output preferences affect welfare. --monetary union,voting power,shocks,output persistence,monetary transmission process,central bank council,labour mobility
Money Illusion Under Test
No full textMuch progress has been made in recent years in developing and applying a direct measure of utility using survey questions on satisfaction with income and with life in general. In this paper we apply this new type of measurement to the study of money illusion. Using data from the German Socio-Economic Panel for the years 1993 to 2003, we cannot reject the hypothesis of no money illusion.North-South, cost-of-living, subjective well-being, fixed effects
