Why Managers Use Cost Allocations: A Research Note

Using an experimental design, this paper investigates empirically the conditions under which managers use cost allocations for decision-making purposes. The paper focuses on decision-risk in the context of short-term decision-making when most capacity costs are unavoidable. Decision-risk is determined in this paper by a combination of two factors: uncertainty and irreversibility. Cost allocations can serve as a reference point for a decision maker to deal with decision-risk. Three hypotheses are formulated: (1) the combination of both uncertainty and decision irreversibility induces the use of cost allocations. However, (2) certainty or (3) decision reversibility alone are not expected to induce the use of cost allocations. The hypotheses were tested in an experiment, in which senior managers participated. The experimental results supported the hypotheses.     

Jacques Le Bourva's theory of endogenous credit-money ∗

About 30 years ago, Jacques Le Bourva published two little-known articles that clearly set out the present post-Keynesian theory of endogenous money developed by Kaldor and Moore. The main features of these two articles are presented, in particular Le Bourva's belief that reverse causation, rather than the instability of the velocity function, is the key objection to the quantity theory of money and the mainstream theory of inflation. Other features include a graphical and an algebraic pedagogical representation of the theory of endogenous money, the use of the Banking school's efflux/reflux mechanism, the dismissal of the money multiplier, and the impossibility of an excess supply of money. Le Bourva's theory of inflation also resembles that adopted by many post-Keynesians, in which price increases due to excessive wage demands and attempts by firms to raise their profit margins to finance investment.     

Optimal financial investments for non-concave utility functions

We prove a formula for the computation of optimal financial investments in an expected utility framework with arbitrary (not necessarily concave) utility functions. This extends classical results on optimal financial investments for strictly concave utility functions and is of importance particularly for applications of prospect theory where the utility function has a convex-concave shape.     

Informal economy, wage goods and accumulation under structural adjustment theoretical reflections based on the Tanzanian experience

Economic development in sub-Saharan Africa under structuraladjustment witnessed the upsurge of informal sector development—thedevelopment of unregulated labour-intensive activities, in partexport-oriented. This paper argues that two factors played animportant role in shaping the dynamics of informal sector development:(1) the process of the relative cheapening of wage goods asa result of their importation, partly financed through foreignaid, thereby lowering unit-labour costs in labour-intensiveproduction, and (2) the processes at work of subsidising realwages by other forms of economic security as a result of multiple,diversified and spatially extended livelihood strategies. Whilethese factors undoubtedly brought a new vitality to economicdevelopment, this paper questions the long-run sustainabilityof this new trend for two reasons. One is its dependence onforeign aid to finance imports. The other is that it does notappear to propel endogenous increases in productivity by achievinggreater synergy in intersectoral linkages between agricultureand industry.
