There are many domains of interests that can utilize ontolologies to use them as the knowledge repository. Economy is one of the widely interesting topics that anyone can relate to. This research simplifies ontologies concepts using economy domain to guide people in the field of economics to understand how ontology works as well as to guide the computer software developers to understand the basic concept of economy. The economy ontology is illustrated in ontology chart and hierarchical chart.

Prior to the amendment these revenues were not distributed to firms. In this article, we formally test the hypothesis that the Byrd Amendment effectively provides double protection to U.S. firms to the extent that it further restricts U.S. imports, as argued by the E.U. and eleven other U.S. trading partners. Using a rich panel of 362 U.S. manufacturing industries for the period 1998 to 2003, we find that whether or not the Byrd Amendment restricted U.S. imports depends crucially on the level of competitiveness in the import-competing industry. Specifically, we find that the Byrd Amendment served to restrict imports only in industries where competition is relatively weak, while the amendment is associated with an increase in imports in more competitive industries.
Gender Differences in Native Preferences towards Undocumented and Legal Immigration: Evidence from San Diego
The literature has noted that native views about legal as opposed to undocumented immigration in ... more The literature has noted that native views about legal as opposed to undocumented immigration in the U.S. differ. Furthermore, native views about immigration are known to vary by gender. Yet, most surveys do not inquire native men and women about their views with regards to the two distinct immigrant groups, thus impeding an analysis of differences in preferences towards legal and undocumented immigrants from the same sample of natives. Using a recent San Diego County survey, we examine differences in native male and female opinions with regards to legal and undocumented immigration and their determinants. Native preferences towards immigration appear to significantly differ by gender as well as according to immigrants' legal status. In addition, public finance and welfare concerns are among the key factors driving native male and female preferences towards legal and undocumented immigration. However, native women's attitudes are also impacted by concerns regarding the soc...

A model is developed to illustrate the trade-off between imitating foreign technologies and encouraging domestic innovation in a developing country's choice of IPRs. It is shown that innovations in a developing country increase in its IPRs, and a country's IPRs can depend on its level of development non-monotonically, first decreasing and then increasing. Empirical analysis, with a panel of data for 64 developing countries, confirms both the positive impact of IPRs on innovations in developing countries and the presence of a U-shaped relationship between IPRs and economic development.

Impact of Universal Health Care Coverage on patient demand for health care services in Thailand

In this paper, we studied the impact of the UC in Thailand on the demand for health care services using hospital level data. We found that the UC program was successful in increasing outpatient demand for health care, particularly the demand from the elderly and the poor. However, outpatient demand for health care dramatically increased during the first year of the program and faded away quickly in subsequent years. In contrast to outpatient demand, the number of inpatient visits and the number of days for which the inpatients were admitted at hospitals declined after the UC program was launched. In this paper, we offer our explanation of these phenomena, highlight problems associated with the UC program, and provide policy recommendations to improve the program.
Revisiting McCallum's Border Puzzle

Although trade economists are not surprised at the existence of a border effect, they do find the significant size of the estimated effect in the empirical literature perplexing. In
How Do Tougher Immigration Measures Affect Unauthorized Immigrants?
Demography, 2013

In a recent and unique survey of Mexican unauthorized immigrants interviewed upon their voluntary return or deportation to Mexico, almost a third reported experiencing difficulties in obtaining social or government services, finding legal assistance, or obtaining health care services. Additionally, half of these unauthorized immigrants reported fearing deportation. When we assess how the enactment of punitive measures against unauthorized immigrants, such as E-Verify mandates, has affected their migration experience, we find no evidence of a statistically significant association between these measures and the difficulties reported by unauthorized immigrants in accessing a variety of services. However, the enactment of these mandates infuses deportation fear, reduces interstate mobility among voluntary returnees during their last migration spell, and helps curb deportees' intent to return to the United States in the near future.

Native preferences toward immigration appear to significantly differ by gender as well as according to immigrants' legal status. In addition, public finance and welfare concerns are among the key factors driving native male and female preferences toward legal and undocumented immigration. However, native women's attitudes are also impacted by concerns regarding the social integration and economic assimilation of undocumented immigrants possibly related to the alleged prejudice factor. (JEL J61, F22) others, discuss how native views with regard to legal immigrants are sharply divided. Differences in native opinions regarding undocumented immigrants are discussed in .
New unit root tests of the Nelson-Plosser data

Due to the greater power of these two tests, unit roots are rejected for three to five of the series.
