  1. \(\mathrm{E}_{\mathrm{j}}\) = Contribution to cake production of player j
  2. \(\mathrm{D}_{\mathrm{j}}\) = Need for cake of player j
  3. Def (Deficiency) = Allocated share of cake \(\left( {\mathrm{N}_{\mathrm{j}} } \right)\)—Need \(\left( {\mathrm{D}_{\mathrm{j}} } \right)\)
  4. *Capitalist: Players receive cake units linearly proportional to their contributions \(\left( {\mathrm{E}_{\mathrm{j}} } \right)\)
  5. **Socialist: Players receive cake units linearly proportional to their needs (\(\mathrm{D}_{\mathrm{j}}\)).
