The present article discusses the trade-offs between markets, organizations and networks in terms of the cognitive means and the values underlying them. It is claimed that the regulative ability of the market is inextricably bound up with the numerical codification of economic activity supported...

An agent-based artificial financial market (AFM) is used to study market efficiency and learning in the context of the Neo-Austrian economic paradigm. Efficiency is defined in terms of the “excess” profits associated with different trading strategies, where excess is defined relative to a...

Economic theory typically assumes the existence of few unobserved unpredictable stochastic disturbances, called structural shocks, driving the whole economy. Would the economy be representable as a very high dimensional stochastic vector process, those shocks would be the reduced rank innovation...

A number of non-parametric estimators have been proposed to calculate average medical care costs in the presence of censoring. This paper assesses their performance both in terms of bias and efficiency under extreme conditions using a medical dataset which exhibits heavy censoring. The...

Hospitals can be reimbursed for their costs in many ways. Several authors have investigated the effects of these reimbursement rules on physician incentives and, therefore, on the quantity of services provided to patients. A form of (linear) cost-sharing tends to emerge as the socially efficient...

We present evidence on the effect of social connections between workers and managers on productivity in the workplace. To evaluate whether the existence of social connections is beneficial to the firm's overall performance, we explore how the effects of social connections vary with the strength...

A simulation model was constructed to assess the relative costs and cost-effectiveness of different screening and vaccination strategies for dealing with hospital incidents of varicella exposure, compared with current policies, using data from published sources and a hospital survey. The mean...

We revisit Western Europe's record with labor-productivity convergence, and tentatively extrapolate its implications for the future path of Eastern Europe. The poorer Western European countries caught up with the richer ones through both higher rates of physical capital accumulation and greater...

Dynastic management is the inter-generational transmission of control over assets that is typical of family-owned firms. It is pervasive around the World, but especially in developing countries. We argue that dynastic management is a potential source of inefficiency: if the heir to the family...

Shifts in the extent of competition, which affect markup ratios, are possible sources of aggregate business fluctuations. Markups are countercyclical, and booms are times at which the economy operates more efficiently. We begin with a real model in which markup ratios correspond to the prices of...
