Host Cell Interaction

The cause of bluecomb disease in turkeys is unknown. Filtration of infective intestinal contents suggests a viral origin. To date, it has not been possible to isolate the etiologic agent in various cell cultures. The purpose of this work was to characterize as many virus-like entities as were recognizable in intestines of both healthy and bluecomb-infected turkeys. By a comparison of the viral populations it was hoped that some insight might be gained into the cause of this disease. Studies of turkey hemorraghic enteritis by Gross and Moore (Avian Dis. 11: 296-307, 1967) have suggested that a bacteriophage-host cell interaction may bear some causal relationship to that disease.

Starting A Business

This study investigates the impact of Ease of Doing Business on Inward FDI over the period from 2011 to 2015 across the globe. This study measures ease of doing business using starting a business, getting credit, registering property, paying taxes and enforcing contracts. The research used a sample of 177 countries from 190 countries listed in World Bank. Least square regression model via E-views software used to examine causal relationship. The study found that ease of doing business indicators ‘Enforcing Contracts’ was found to have a positive significant impact on Inward FDI. Nevertheless, ‘Getting Credit’ and ‘Registering Property’ were found to have a negative significant impact on Inward FDI. However, ‘Starting a Business’ and ‘Paying Taxes’ have no significant impact on Inward FDI in the studied timeframe of this research. The findings of the study suggested the ease of doing business enables inward FDI through better contract enforcements, getting credit and registering property. The findings of the research will assist international managers and companies to know the importance of ease of doing business when investing in foreign countries through FDI.

Econometric Technique

We study the tax-spend nexus for Russian regional budgets. Causal relationship running from taxing to spending is found, thus supporting the concept “tax and spend” suggested by M. Friedman. Next, elasticity of expenditure by revenue is estimated for a panel of 80 regional budgets basing on data for 2000—2017. Estimates are in the range of 0.72 to 0.78 (depending on the econometric technique), which exceeds elasticity for the federal budget more than twice. This evidences that fiscal policy at the sub-federal (as distinct from the federal) level has clear pro-cyclical nature. Besides, the largest sensitivity of expenditure to revenue shocks is found for the item “national economy”, implying marked adverse implications for economic growth. We suggest to mitigate this effect by modifying fiscal rules for sub-federal budgets. They are currently aimed primarily at enhancing fiscal discipline, with less emphasis on countercyclical policy, insulating economy from fiscal shocks.
