Nitrogen (N) export from soils to streams and groundwater under the intensifying cropping schemes of the Pampas is modest compared to intensively cultivated basins of Europe and North America; however, a slow N enrichment of water resources has been suggested. We (1) analyzed the fate of fertilizer N and (2) evaluated the contribution of fertilizer and soil organic matter (SOM) to N leaching un...

Subsidized health care benefits would be guaranteed for early retirees ages fifty-five to sixty-four under President Bill Clinton's health care reform proposal. This is an important policy issue because persons in this age group are the least likely age cohort of the nonelderly population to be working. They are also the most likely to face high and uncertain health care costs. Previous researc...

In this paper, I analyze the setting of ticket prices when teams receive subsidization from the public. I model teams as entertainment providers, where entertainment is generated by selling wins and amenities. I argue that subsidization of teams generally comes from subsidizing the amenities in and surrounding the teams’ stadiums. Subsidization of the amenities lowers the marginal cost of provi...

It is well known that in linear programming, the optimal values of the dual variables can be interpreted as shadow prices (marginal values) of the right-hand-side coefficients. However, this is true only under nondegeneracy assumptions. Since real problems are often degenerate, the output from conventional LP software regarding such marginal information can be misleading. This paper surveys and...

Non-point source (NPS) pollution has been increasingly serious in China since the 1990s. The increases of agricultural NPS pollution in China is evaluated for the period 2000-2008 by surveying the literature on water and soil pollution from fertilizers and pesticides, and assessing the surplus nitrogen balance within provinces. The main causes for NPS pollution were excessive inputs of nitrogen...

AlgaeSim, a dynamic multiple-systems (C, N, P) mass balance model, was developed to explore the potential for algae biomass production from wastewater by coupling two photobioreactors into the main treatment train at a municipal wastewater resource recovery facility (WRRF) in Tampa, Florida. The scoping model examined the synergy between algae cultivation and wastewater treatment through algal ...

The competition among business actors often leads to unfair competition, whether in the form of prices or non-prices. practice anti-dumping is an important issue conducting international trade achieve fair trade. Anti-dumping import duties are regulated Article 19 (1) Customs Law No.10 1995 that imposed on imported goods at most equal difference between normal value and export price with a maxi...

Following the damaging real effects of asset price fluctuations over the recent financial crisis, the debate on the appropriate role of such prices in a monetary policy context has gained renewed attention. This paper argues that a direct monetary policy response to asset prices is not desirable under common instrumental rate rules. To illustrate this point, we build an adaptive learning model,...

The Patient Protection and Affordable Care Act includes several provisions that promise to stem the rapidly rising tide of uninsured young adults, one of the largest uninsured segments of the population. These include the ability to enroll in a parent's health plan up to age 26, beginning in September 2010; significant expansion in eligibility for Medicaid, beginning in 2014; and the creation o...

This paper investigates Euler equations involving security prices and household-level consumption data. It provides a useful complement to many existing studies of consumptionbased asset pricing models that use a representative-agent framework, because the Euler equations under investigation hold even if markets are incomplete. It also provides a useful complement to simulation-based studies of...
