    Notes: Our previous results have demonstrated that Phanerochaete flavido-alba decoloration, dephenolization and detoxification of olive oil mill wastewater (OMW) were associated with changes in the ligninolytic major exoenzymes accumulated in the cultures. This paper describes the effect of the two main OMW components (monomeric aromatic compounds and a major brownish polymeric pigment), on extracellular P. flavido-alba ligninolytic enzymes. Laccase was the sole ligninolytic enzyme detected in cultures containing monomeric aromatic compounds. Laccase and an acidic manganese-dependent peroxidase (MnPA, pI〈2.8) were accumulated in cultures with OMW or polymeric pigment. Also, modified manganese-dependent peroxidases were observed mainly in OMW-supplemented cultures. Laccase was more stable to the effect of OMW toxic components and was accumulated in monomeric aromatic-supplemented cultures, suggesting a more important role than manganese-dependent peroxidases in OMW detoxification. Alternatively, MnPA accumulated in cultures containing the polymeric pigment seems to be more essential than laccase for degradation of this recalcitrant macromolecule by P. flavido-alba.

    Long-Term or Short-Term Managerial Incentive Contracts (1996)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of economics & management strategy 5 (1996), S. 0

    Notes: This paper deals with the strategic role of the temporal dimension of contracts in a duopoly market. Is it better for a firm to sign long-term incentive contracts with managers or short-term contracts? For the linear case, with strategic substitutes (complements) in the product market, the incentive variables are also strategic substitutes (complements). It is shown that a long-term contract makes a firm a leader in incentives, while a short-term contract makes it a follower. We find that, under Bertrand competition, in equilibrium one firm signs a long-term contract and the other firm short-term incentive contracts; however, under Cournot competition, the dominant strategy is to sign long-term incentive contracts.

    Corporate merger, organizational form, and control of labor (2000)

    Notes: Abstract. This paper shows that, when two firms merge, the increase in the bargaining strength of the multiproduct firm arising from the merger when negotiating uniform wages with the workers is one of the reasons that account for corporate mergers. Moreover, there is a strategic variable that can be used to decrease union rents in the case of merging, namely, the organization of production decisions.
