Bernardo and Ledoit (2000) develop a very appealing framework to compute pricing bounds based on the so-called gain-loss ratio. Their method has many advantages and very interesting properties and so far one important drawback: the complexity of the numerical computation of the pricing bounds....

We use the neoclassical growth framework to model international capital flows in an economy with exogenous demographic change. We compare model implications and actual current account data and find that the model explains a small but significant fraction of capital flows between OECD countries,...

In this paper we discuss the significant computational simplification that occurs when option pricing is approached through the change of numeraire technique. The original impetus was a recently published paper (Hoang, Powell, Shi 1999) on endowment options; in the present paper we extend these...

Walter Korpi argues in a previous issue of Challenge (March/April 2000) that Swedish economists' claim that Sweden's growth performance has been inferior to that of other industrialized countries is at odds with the facts. Since Sweden has not grown slowly relative to other countries, there is...

This paper investigates the relative labor productivity level for total manufacturing in Germany, Sweden and the US for the period 1980-2001. The paper also presents estimates of labor productivity levels for 18 different manufacturing industries for the period 1993-2000. The results show that...
