This paper develops an original measure of learning in higher education, based on grades in subsequent courses. Using this measure of learning, this paper shows that student evaluations are positively related to current grades but unrelated to learning once current grades are controlled. It offers evidence that the weak relationship between learning and(More)
This paper considers a nonlinear pricing framework with both horizontally and vertically differentiated products. By endogenizing the set of consumers served in the market, we are able to study how increased competition affects nonlinear pricing, in particular the market coverage and quality distortions. We characterize the symmetric equilibrium menu of(More)
We show that an input-output matrix is a directed weighted network. We develop and apply a measure of betweenness centrality based on random walks. This notion of centrality has an analogy as a current flow in an electrical circuit. We apply this measure to recent data from the major industrial economies. Wholesale and Retail Trade is the most central(More)
We analyze input-output matrices for a wide set of countries as weighted directed networks. These graphs contain only 47 nodes, but they are almost fully connected and many have nodes with strong self-loops. We apply two measures: random walk centrality and one based on count-betweenness. Our findings are intuitive. For example, in Luxembourg the most(More)
This paper analyses a model of overlapping generations in which agents who do not participate in the labor market are unable to borrow. Thus an increase in a fully funded pension raises aggregate savings even with a fixed participation rate since private savings are not crowded out one-for-one. When labor force participation is determined endogenously, a(More)

Abstract An average adjustment cost which is convex with respect to the rate of gross investment successfully calibrates a neoclassical growth model to match real world observables(More)
Apolipoprotein B (apoB) is the main protein component of very low density lipoprotein (VLDL) and is necessary for the assembly and secretion of these triglyceride (TG)-rich particles. Following release from the liver, VLDL is converted to low density lipoprotein (LDL) in the plasma and increased production of VLDL can therefore play a detrimental role in(More)
Extending Ireland's (1994) model, this paper analyzes an international economy where cash or credit can be used for payment. Foreign trade credit is more costly than its domestic analog. A depreciation of the real exchange rate is associated with an external surplus and a reduced share of imports purchased with credit. Economic growth slows when foreign(More)
