This paper introduces the concept of a steepest ascent tariff reform for a small open economy. By construction, it is locally optimal in that it yields the highest gain in utility of any feasible tariff reform vector of the same length. Accordingly, it provides a convenient benchmark for the...

We show that the standard concertina result for tariff reforms – i.e. lowering the highest tariff increases welfare – no longer holds in general if we allow for international capital mobility. The result can break down if the good whose tariff is lowered is not capital intensive. If the...

Reducing tariffs and increasing consumption taxes is a standard IMF advice to countries that want to open up their economy without hurting government finances. Indeed, theoretical analysis of such a tariff-tax reform shows an unambiguous increase in welfare and government revenues. The present...

Economic activities are highly clustered. Why is geographic concentration becoming a predominant feature of modern economies? On the basis of the empirical models developed by the 'new' theories of international trade, our answer is that increasing returns are the driving force of economic...

This study explores the relationship between demographic factors and saving rates using a panel dataset covering 110 countries between 1963 and 2012. In line with predictions from theory, this paper finds that lower dependency rates and greater longevity increase domestic saving rates. However,...

This paper deals with some variables that are not generally included as economic or market variables in order to show how these affect the question of population growth, which is after all the core of resource allocation. It shows that population growth may also depend on better medical...
