What, another paper on the new economy? When financial markets are raking through the debris of $8 trillion in lost equity value, and “.com” is a reviled four-symbol word, a paper on the impact of the new economy on productivity would seem as welcome as an analysis of the role of whales in the lighting revolution. In fact, the new economy (or, more precisely, information technologies) continues...

distribution income show how national income divide between economic sectors and social groups. it effect on social justice and many factors effect on it, such as productivity of labor force and employment rate. in this paper, factors affecting distribution income, especially productivity of labor force have been analyzed by panel data model for 32 countries during 1998-2005. the results show e...

In brane inflationary scenarios, the cosmological perturbations are supposed to originate from the vacuum fluctuations of the inflaton field corresponding to the position of the brane. We show that a significant, and possibly dominant, contribution to the curvature perturbation is generated at the end of inflation through the vacuum fluctuations of fields, other than the inflaton, which are lig...

The introduction of a ‡at tax is supposed to have several advantages. Administration and compliance costs are reduced, as well as incentives for tax evasion. Furthermore, positive employment and growth e¤ects are expected. Despite these advantages, a ‡at rate tax is not very popular in most Western European countries. The most important objection against a ‡at tax states that a ‡at rate tax wou...

Joint modelling of fiscal and monetary policies should elucidate on their interaction. We estimate a large parsimonious structural vector equilibrium correction model (PSVECM) to analyse the dynamics of eight variables from the US economy. Shocks to fiscal and monetary variables reveal interesting observations, with the results broadly in agreement with economic theory. A shock to only governme...

This project examines fiscal reforms in Brazil since the 1990s, particularly in taxation, budgeting, and fiscal federalism. While recentralizing fiscal authority and massively expanding the extractive capacity of the state, policymakers chose not to revamp an inefficient tax system that has nonetheless proven capable of generating high levels of revenue. In budgeting, the economic crises of the...

The obesity epidemic is also an economic tragedy. This analysis evaluates the economic effects and the potential to improve the well-being of both individual and societal wealth. Econometric techniques should carefully assess the degree to which obesity affects declines in business output, employment, income, and tax revenues at the regional and national levels. Microeconomics assesses lost pro...

This paper investigates the economic impact of the government's proposed new UK R&D tax credit. We measure the benefit of the credit by the effect on value added in the short and long_run. This is simulated from existing econometric estimates of the tax_price elasticity of R&D and the effect of R&D on productivity. For the latter we allow R&D to have an effect on technology transfer (catching u...

In this paper we survey the historical record for over two centuries on connection between expansionary fiscal policy and inflation. As a backdrop, briefly lay out several theoretical approaches to effects of deficits inflation: earlier Keynesian monetarist approaches; modern incorporating expectations forward looking behavior: unpleasant arithmetic theory price level.We find that relationship ...

We propose a monetary model which features endogenous market incompleteness. Our framework combines the tractable features of competitive search with matching frictions of Menzio et al. (2013) with a costly participation model in a centralized market with complete insurance. Equilibrium market incompleteness arises because of: (i) an externality trading off matching opportunities with consumpti...
