Two additional new compounds, pseudellone D (1) and (5S,6S)-dihydroxylasiodiplodin (3), along with the two known compounds lasiodipline F (2), (5S)-hydroxylasiodiplodin (4) were isolated from the marine-derived fungus Pseudallescheria ellipsoidea F42-3 associated with the soft coral Lobophytum crassum. Their structures, including absolute configurations, were elucidated on the basis of the corr...

This paper examines information sharing between governments in an optimal taxation framework. We present a taxonomy of alternative systems of international capital income taxation and characterize the choice of tax rates and information exchange. The model reproduces the conclusion of the previous literature that integration of international capital markets may lead to the under-provision of pu...

This paper analyses the evolution of the business cycle worldwide synchronization since 1960. For that, it purposes a correlation index that allows to measure the cross-country synchronization period per period rather than using time windows. This new methodlogy allows to control for outliers when synchronizion across countries increased/droped unexpectedly in single years, and so, it can check...

In this paper the optimal choice of a monetary target is investigated for a small open economy that is subject to foreign monetary policy shocks. In contrast to large parts of the literature, pegging the exchange rate is never the best policy choice for the small open economy in our model. Instead, monetary targeting and, depending on the parameter combination, producer price index targeting co...

This paper projects the future of knowledge economy (KE) in SSA and MENA countries using the four components of the World Bank’s Knowledge Economy Index (KEI): economic incentive, education, ICTs and innovation. The empirical evidence provides the speeds of integration as well as the time necessary to achieve full integration. Findings broadly indicate SSA and MENA countries with low levels in ...

This paper analyzes optimal copyright levies in a representative consumer model and derives welfare implications for harmonization of levy rates. When the policymakers place enough weight on the interests of collecting societies, harmonization could lead to a reduction in social welfare. When countries are asymmetric, the country with a larger proportion of foreign consumption and more ine¢ cie...

Using a competitive two-country two-commodity monetary model with optimizing agents in which persistent unemployment arises, this paper examines the effects of trade restrictions on consumption and employment in the two countries. When facing unemployment, a country tends to impose an import restriction so that domestic firms will increase production and raise employment. However, this policy i...

This paper is a pioneering attempt to include India with east and Southeast Asia to study the existence of the economic criteria for a common currency. The analysis in this paper shows that significant complementarities in trade exist among these countries, most of them experience similar shocks and labor mobility is already present. These results point to the fact that the cost of adopting a s...
