The total surplus-value, as well as the total profit, which is only the surplus value itself, computed differently, can neither grow nor decrease through this operation [the equalization of profit rates], ever; what is modified thereby is not it, but only its distribution among the different capitals. However, this examination belongs only with that of the many capitals, it does not yet belong ...

A typical strategy for dealing with commodity surpluses is to store them for future sale; though electricity cannot yet be stored on a large scale, this storage strategy will become a natural choice for dealing with electricity surpluses. However, because electricity prices can be negative, there exists another potential strategy: To buy electricity surpluses at negative prices and dispose of t...

About the theory and empirical analysis of " the persistence of profit " and its applicability to Colombia Abstract. This paper looks into the application of the theory of " the persistence of profits " and how it can be used to model manufacturing industries in Colombia. By explaining where the theory of " persistence of profits " comes from, what it is, and what its determinants are brief des...

This paper develops a structural evolutionary microeconomic model where the forces of chance and selection are at work and matches this model to data. As a concrete example we explore the process of industry concentration by modeling bottom-up starting with profit maximizing firms and introducing stochastic elements at various levels of the market. An estimation procedure is developed to connec...

Entrepreneurial activity is presumed to generate important spillovers, potentially justifying tax subsidies. How does the tax law affect individual incentives? How much of an impact has it had in practice? We first show theoretically that taxes can affect the incentives to be an entrepreneur due simply to differences in tax rates on business vs. wage and salary income, due to differences in the...

With increasing fishing pressures having brought several stocks to the brink of collapse, there is a need for developing efficient harvesting methods that account for factors beyond merely yield or profit. We consider the dynamics and management of a stage-structured fish stock. Our work is based on a consumer-resource model which De Roos et al. (in Theor. Popul. Biol. 73, 47-62, 2008) have der...

OBJECTIVES Since the Cabinet's decision concerning the Basic Policies 2005, the Japanese government has implemented specific measures to suppress increases in national medical care expenditure. However, we believe that the economic significance of medical care should be quantified in terms of its economic impact on national medical care expenditure. No one has examined the economic impact of al...

In a rapidly growing industry, potential entrants strategically choose which local markets to enter. Facing the threat of additional entrants, a potential entrant may lower its expectation of future profits and delay entry into a local market, or it may accelerate entry due to preemptive motives. Using the evolution of local market structures of broadband Internet service providers from 1999 to...

Profit Sharing and Workplace Productivity: Does Teamwork Play a Role? The conditions under which profit sharing affects workplace productivity have never been fully understood. Using panel data, this paper examines whether there is any link between adoption of an employee profit sharing plan and subsequent productivity growth in Canadian establishments, and whether this relationship is affected...

Empirical evidence indicates that there can be persistent profit differentials between firms in an industry. We show that demand uncertainty and costly information acquisition by firms on market demand leads to significant profit differentials for intermediate levels of demand variability.  2000 Elsevier Science S.A.
