The present paper thoroughly explores second-best efficient allocations in an adverse selection insurance economy. We start from a natural extension of the classical model, assuming less than perfect risk perceptions. We propose first and second welfare theorems, by means of which we describe efficiencyenhancing policies. Notions of weak and strong adverse selection are promising for interpreti...

OBJECTIVE To evaluate the use of the ML Flow test as an additional, serological, tool for the classification of new leprosy patients. DESIGN In Brazil, Nepal and Nigeria, 2632 leprosy patients were classified by three METHODS : (1) as multibacillary (MB) or paucibacillary (PB) according to the number of skin lesions (WHO classification), (2) by slit skin smear examination, and (3) by serolo...

In this paper, we empirically investigate the relationship between oil price changes and output in a group of oil exporting countries. The dynamics of business cycles in Libya, Saudi Arabia, Nigeria, Kuwait, Venezuela and Qatar are modeled by alternative regime switching models. We show that the extension of uni-variate Markov Switching model in order to include oil revenue improves dating busi...

abstract the purpose of this paper is to test the hypothesis first proposed by romer (1993); suggesting that inflation is lower in more open economies. according to this hypothesis, central banks have a lower incentive to engineer surprise inflations in more-open economies because the phillips curve is steeper. furthermore, comparing with other empirical studies, this paper has used the new kof...

Several studies abound that concentrated on oil production and the environment, exploration socio-economic conditions, contributions of crude consumption to growth Nigerian state, etc. But there are no recent investigating production- GDP nexus. Hence, main goal this study is explore contribution national from an oil-dependent economy Annual time series data its rate represented side nexus whil...

An identity links the rate of economic growth, the speed of poverty reduction and changes in the distribution of income during some time period in a given country. A few authors used that identity to understand the causes for observed changes in poverty and to identify the exact role of economic growth in poverty reduction. Yet, many empirical cross-country studies of the relationship between g...

This paper explains why the overall stance of monetary policy is effected by both interest rates and the exchange rate, and hence why a Monetary Conditions Indicator can provide useful information about the stance of policy. Three output gap equations estimated in this paper reveal that the real interest rate and the real exchange rate both affect excess demand but that the real interest rate i...

i n the past decades, the effect of different tax amendments on various economic issues has been studied. the majority of these studies have avoided considering shadow economy as part of the calculation and analysis, and an issue, which has received little attention, is the relationship between green tax reforms and shadow economy, as for informal labor, which is well-connected to unemployment ...
