Price elasticity of demand measures how much, in terms of percentage change, the quantity demanded responds to a change in price. In this pedagogical note, first we intuitively introduce the very first notion of price elasticity, which is a directional measure because it describes the impact of...

During the production process one should operatively survey pre-established (standard) costs with a view of determining and analyzing deviations as costs are settled at the level of an activity considered to be normal while real activity can display deviations from this. The system of analysis...

In this paper, the author analyzes the behavior of local governments in capital taxation when the financial choices in terms of the quality of public goods are made done by a central planner. More specifically, he asks the question of whether a local government has an interest in taxing the...

The 2008-2009 global recession, which originated in developed economies, has rapidly spilled over worldwide, hitting different economies with various intensity. The Macedonian economy was not an exception - the export sector suffered heavily, expectations deteriorated and household consumption...

The standard economic choice model assumes that the decision maker chooses from <i>sets</i> of alternatives. In contrast, we analyze a choice model in which the decision maker encounters the alternatives in the form of a <i>list</i>. We present two axioms similar in nature to the classical axioms of choice...

A decision maker needs predictions about the realization of a repeated experiment in each period. An expert provides a theory that, conditional on each finite history of outcomes, supplies a probabilistic prediction about the next outcome. However, there may be false experts without any...

This paper develops a simple model in which a social hierarchy emerges endogenously when agents form a network for complementary interaction (``activity''). Specifically, we assume that agents are ex ante identical and their best response activity, as well as their value function, increases...

We consider a matching model in which individuals belonging to two populations (\textquotedblleft males\textquotedblright\ and \textquotedblleft females\textquotedblright ) can match to share their exogenous income risk. Within each population, individuals can be ranked by risk aversion in the...

This paper analyzes the effect of competition in a dynamic contest in which agents of two types (A and B) differ in their expected performances; environments where type A outperforms type B are more frequent than those where B outperforms A. In each period, the population of agents is randomly...

We characterize axiomatically a stochastic choice model, the consistent-mistakes model (CMM), that describes an error-prone decision maker's choices. In contrast to random utility models, CMMs generate closed-form choice probability. Under the axioms, we uniquely identify from the choices an...
