e_{n}/3 ≤ dist(x, V_{n}) ≤ 3e_{n}

for any n ≥ n_{o}. By using the above theorem, we prove both Shapiro’s and Tyuremskikh’s theorems for Fréchet spaces. Considering rapidly decreasing sequences, other versions of the BLT theorem in Fréchet spaces will be discussed. We also give a theorem improving Konyagin’s result for Banach spaces.

Covering topical areas of interest such as tradable permit markets, common property and public goods, regulation and compliance and valuation and preferences, the critical advantage of this volume is that each section concludes with discussion points written by economists who do not use experimental methods.
