Considering households in inter-industry models is an important issue for building a realistic macroeconomic model. This is why we examine three attempts to close the Leontief input-output model, the classical approach (Type I and Type II multipliers), ten Raa model, and Klein model. Then we...

Using France as our main example, we show there is a much scope for improving the SCImago ranking. We detect problems of nomenclature, double affiliation, aggregation and of bias toward large public-funded research organizations. The examples we cite suggest that only detailed knowledge of the...

When evaluating the impact of pollution, measurements from remote stations are often weighted by the inverse of distance raised to some nonnegative power (IDW). This is derived from Shepard's method of spatial interpolation (1968). The paper discusses the arbitrary character of the exponent of...

Pressure to change the academic reviewing system is growing. We discuss two groups of proposals for introducing market mechanisms. First, Prüfer and Zetland (2009), based on Havrilesky (1975), create an auction system: manuscripts are submitted and auctioned to editors in "academic dollars",...
