We consider a regulated monopolist that faces a continuum of markets (e.g., [0, 1]) although a finite number k of prices must be charged. As a function of the integer k, we provide the optimal profit policy defined as the optimal market segmentation and the discriminatory prices. The social welfare is maximized for three prices, but the result is far below the benchmark, the welfare under the R...

PRocH is a proof reconstruction tool that imports in HOL Light proofs produced by ATPs on the recently developed translation of HOL Light and Flyspeck problems to ATP formats. PRocH combines several reconstruction methods in parallel, but the core improvement over previous methods is obtained by re-playing in the HOL logic the detailed inference steps recorded in the ATP (TPTP) proofs, using se...

Input-output models are useful tools for regional science owing to their ability to capture many of the distinguishing features of a regional economy. Since input-output tables are hard to find at the regional level, many researchers adopt nonsurvey techniques to derive regional input-output tables (RIOTs). Numerous methods have been suggested and this has spawned a stream of literature compari...

Today we see a healthy diversity of projects aiming to harness Java for scientific (or “Grande”) computing. A number of these approaches were reviewed in a recent article in this series. In this article we will focus instead on one particular project of this kind, ongoing at our labs in Indiana University. The HPJava project aims to support scientific and parallel computing in a modern object-o...

1668 The smaller the volume (or share) of imports from the trading partner, the larger the impact of a preferential trade agreement on home country welfare—because the smaller the imports, the smaller the loss in tariff revenue. And the home country is better off as a small member of a large bloc than as a large member of a small bloc. Summary findings There has been a resurgence of preferentia...

Economic theories show that the direction and magnitude of the fluctuations of economic variables depend on the type and magnitude of the shocks they are faced with. Various reasons are noted for fluctuations in demands for imports, including productivity shocks. Accordingly, this research was aimed at identifying the effects of Total Factor Productivity (TFP) shocks of the agricultural sector ...

The share of Chinese manufacturing imports in U.S. consumption has increased eight-fold between 1993 and 2011, from 1 to over 8 percent. While the literature has documented the pro-competitive price effect of the rising Chinese import competition on U.S. industries, I provide new empirical evidence for a quantitatively larger, indirect effect: for the average manufacturing industry, the increas...

The poorest nations of the world suffer from extreme disease burdens, which golargely untreated because weak incomes and the prevailing system of intellectualproperty rights fail to provide sufficient incentives to develop new treatments anddistribute them at low cost. Recent price reductions for HIV/AIDS drugs are encouragingbut offer only a limited solution. We discuss the...
