Monopolistic Competition: Beyond the Constant Elasticity of Substitution

We propose a model of monopolistic competition with additive preferences and variable marginal costs. Using the concept of “relative love for variety,” we provide a full characterization of the free‐entry equilibrium. When the relative love for variety increases with individual consumption, the market generates pro‐competitive effects. When it decreases, the market mimics anti‐competitive behavior. The constant elasticity of substitution is the only case in which all competitive effects are washed out. We also show that our results hold true when the economy involves several sectors, firms are heterogeneous, and preferences are given by the quadratic utility and the translog.     

Addressing Unmet Needs in Incarcerated Women With Co-occurring Disorders

ABSTRACT

This article will present findings related to critical needs in a group of 281 incarcerated women with co-occurring disorders. The women completed interviews while incarcerated and again at various time points after community reentry. Findings revealed that the number of basic needs increased over time, and a low level of social support was related to negative outcomes. Recommendations for this population include holistic evaluation assessments and integrated treatment plans that encourage staff to comprehensively assess clients at intake and link them to support services during and after incarceration. Implications of this female empowerment model will be discussed.
